- Ka whakanuia e ngā āhuarangi pārūrū te nekehanga wera o te WPC. Me ngā panonitanga o te pāmahana o te ao i waenganui i te 15-25°C me te haumākū nui puta noa i te tau, hiato rakau-kirihou He nui ake te whānui me te whakawhāiti o ngā papa i ngā rohe ekueta i ērā i ngā rohe mahana — he mea nui rawa te whakatakotoranga tika o ngā āputa mai i te rā tuatahi.
- I whakaputahia ngātahitia He pai ake te pumau o ngā āhuatanga o ngā papa WPC (pēnei i te YDWPC YD140RH23 me te YD140S23) ki te whakataurite ki ngā kōtaha WPC tawhito. nā te mea ka tiakina te matua e te paparanga taupoki polymer mai i te mimiti tika o te UV me te urunga o te makuku, ka whakaiti i te tauwehenga whānui rārangi tae atu ki te 30% ki te whakataurite ki ngā papa kāore i te taupokina.
- I a YDHua WpcHe mea hanga ēnei mō te pumau o ngā āhuatanga, ko ngā whakaritenga mō te āputa whānui ka whakawhirinaki ki ngā āhuatanga o te rangi o te rohe, te aronga tāutanga, me te roa o te papa. Tirohia te aratohu tāutanga a te kaihanga mō ngā taunakitanga motuhake mō te kaupapa. Ngā tohutoro ahumahi pēnei i I roto i te 15534 me ASTM D7032 whakarato i ngā anga whakamātautau paerewa mō te aromatawai i te nekehanga wera o te WPC.
- He mea nui te whakatakotoranga o te papa ki te whānui. I roto i ngā whakaurunga pārūrū, me tohu tonu ngā āputa whānui mai i te pito ki te pito i ngā hononga papa me ngā āputa taha-ki-taha i waenganui i ngā papa whakarara. Ko ngā kōtaha YDWPC whakakotahi-whakaputa 140mm te whānui e hiahia ana kia iti ake ngā mita rārangi katoa o te āputa i ngā kōtaha tawhito 150mm mō te rohe hipoki kotahi — he painga utu me te ataahua mō ngā papa arumoni nui.
- He wārangi iti mō te 15-25 tau te roa o te papa whakapūtanga-tahi YDWPC. ā, e hangaia ana i raro i te ISO 9001 te whakahaere kounga i tō mātou whare i Ningbo. Mō ngā whakatakotoranga kaupapa pārūrū, whakapā atu ki tā mātou tīma kaweake mō ngā pepa raraunga tāutanga motuhake mō te rohe.
Ko te whakawhanuitanga wera te whakaritenga e tino warewarehia ana i roto i te hoko papa WPC mō ngā kaupapa e tata ana ki te rangi me te hauāuru. Kei raro nei, ka tirotirohia e tā mātou tīma hangarau kaweake te ahupūngao o te nekehanga wera o te WPC, te pūtaiao rauemi e wehewehe ana i ngā kōtaha kua whakakotahihia mai i ngā kōtaha tawhito, me te anga whakaritenga āputa mahi e tika ana kia tonoa e ngā kaituku me ngā kaimahi kirimana mai i tētahi kaihanga WPC i mua i te hainatanga i tētahi ota hoko kaupapa toropika.
Ngā Whakaaro Matua
- He iti ake te horapa wera o te WPC i whakapūtāhia tahitia i te WPC tawhito nā tōna paparanga potae polymer.
- I ngā āhuarangi pārūrū (ngā piki me ngā heke o te pāmahana 30-40°C) me 7-8 mm ngā āputa i ngā oma 12 m, ā, me 5-6 mm i ngā rohe mahana.
- Ko te EN 15534 me te ASTM D7032 te anga whakamātautau mō ngā kereme pumau ā-ahu o te WPC.
- He pai ake te whakauru a ngā pūnaha whakapiri huna i te nekehanga wera i ngā tāutanga tīwiri mata.
- He mea nui te tawhiti o te anga-iti me te hoahoa o te rerenga wai, pērā i te āputa whānui tonu.
He aha ngā āhuatanga o te rangi pārūrū e whakarerekē ana i te tātaitanga o te āputa whānui
Te whakawhānui wera he āhuatanga rauemi, ehara i te kōwhiringa hoahoa — engari ko te taiao te mea e whakatau ana i tōna hiranga. Ia rakau whakakotahi ka neke te hua ina rerekē tōna pāmahana. tauwehenga o te whakawhānui raina Mō ngā papa WPC noa, ko te pāmahana kei waenganui i te 3.0 × 10⁻⁵ ki te 5.5 × 10⁻⁵ ia °C, i runga i te ōwehenga rakau-muka-ki-pūmua, te momo pūmua (HDPE vs. PP), me te mea kua taupokina, kua wetekina rānei te papa. Ka whānui te papa WPC 3.6m te roa i te 20°C i runga ake i tōna pāmahana tāutanga i waenga i te 2.2mm me te 4.0mm i tōna roa — he nekehanga, ki te kore e tau ki roto, ka puta he ahotea pēhi i ngā pūwāhi whakapiri, ā, ka mutu ka piko, ka piko, ka kume rānei te tīwiri.
I ngā āhuarangi mahana, ka āta haere tēnei nekehanga i roto i ngā huringa o te wā. Ka whakatakotohia e ngā kaiwhakauru he āputa i te puna, ā, ka eke te papa ki te tihi o te whānui i te raumati, kātahi ka whakawhāiti anō i te ngahuru. I roto ngā āhuarangi pārūrū, ka puta te huringa whakawhānui-whakaiti kotahi i ia rā. Tērā pea ka pāngia tētahi papa o Singapore, Bangkok, Jakarta rānei e te pikinga o te pāmahana o te mata i waenganui i te ata me te ahiahi — i ia rā, i te tau katoa. Kāore ngā papa e okioki i te taurite mō ngā haora maha, ko te tikanga ka pāngia ngā hononga whakapiri, ngā topenga, me ngā hononga pou e te huringa ngenge e kore e kitea e ngā papa o ngā rohe mahana.
Ko ngā tirohanga mara a tā mātou tīma kaweake puta noa i te Tonga-mā-rāwhiti o Āhia (e kapi ana i ngā kaupapa papa arumoni me ngā papa noho 47 i tāutahia i waenga i te tau 2020 me te 2025 i Singapore, Malaysia, Thailand, Vietnam, me Indonesia) e whakaatu ana i tētahi tauira ōrite: Kāore he amuamu mō te piko, te whanoke rānei mō ngā papa e tāutahia ana me ngā āputa motuhake mō ngā rohe pārūrū, engari ko ngā papa e tāutahia ana me ngā āputa paerewa mō te rohe mahana (e tohua ana mō te rerekētanga 10-15°C) ka puta he ahotea hononga kitea i roto i ngā marama 12-18. Kāore te aratau rahunga i te tino nui — ka tīmata hei pēhanga iti i ngā hononga o te papa, ka neke haere ki te whakarerekētanga o te topenga, ā, i te mutunga ka puta he nekehanga papa e kitea ana ka whakaoho i ngā karangatanga a te kaihoko me ngā kereme whakamana a te kaituku.
| Tawhā | Āhuarangi Mārie (hei tauira, Rānana, Pereni) | Taurangirangi (hei tauira, Singapore, Jakarta) |
|---|---|---|
| Awhe pāmahana ā-tau | -5°C ki te 35°C (whānuitanga 40°C) | 23°C ki te 38°C (15°C te whānui) |
| Te tūnga o ia rā i te awatea (te mata o te papa) | 8-12°C (huringa ā-wā) | 15-25°C (huringa o ia rā) |
| Te pāmahana mata teitei (te rā tika) | 55-65°C (te poutumarotanga o te raumati) | 60-75°C (poutūtanga o te tau) |
| Makuku whanaunga | 40-70% (rerekētanga ā-wā) | 70-90% (teitei puta noa i te tau) |
| Ngā huringa whakawhānui ia tau | ~365 (pōturi te wā) | ~365 (tere ia rā) |
| Te ahotea ngenge whai hua i runga i ngā here | Iti (hurihuri āta haere) | Teitei (tere te eke pahikara i ia rā) |
Kia mōhio: Ka inehia ngā raraunga pāmahana o te mata ki te inemahana whero-whero i runga i ngā papa WPC tae pouri i raro i te rā tika o te pārūrū i te poutumarotanga o te rā, te teitei
E whakaatu ana te ripanga i runga ake nei i tētahi āhua rerekē: ahakoa he whāiti ake te awhe pāmahana ā-tau o ngā āhuarangi pārūrū, he nui ake te ahotea ngenge ki ngā whakapiri o te papa nā te mea he kaha ake te huringa wera o ia rā, ā, kāore e mutu. I Rānana, ka whakawhanuitia te papa o te waka i te raumati, ka whakawhāititia hoki i te takurua — 12 ngā huringa nui i te tau. I Hingaiapō, ka whakawhanuitia te papa o te waka i ia ahiahi, ka whakawhāititia hoki i ia pō — 365 ngā huringa i te tau. Ko te ngenge o te pūmau i roto i te wā whakamana 10-tau he 30x teitei ake i ngā rohe werawera, koia te take he mea nui te whakatakotoranga āputa me te whiriwhiri pūmau, kaua ki te tāuta noa.
WPC Whakapūmau-tahi me te WPC Matarohia: Ko tēhea Kōtaha e Pai Ake Ana te Whakahaere i te Nekehanga Toropika?
Kāore e rite te nui o te nekehanga o ngā papa WPC katoa, ā, ko te tukanga hanga te mea matua e rerekē ai. He rerekē te whanonga o ngā papa WPC matua e rua i te mākete o te ao — te matarohia (kāore he taupoki) me te papa i whakapūtāhia (he taupoki) — i raro i te ahotea wera werawera nā te mea he rerekē te āhua o ō rātou hanganga rauemi ki te ārai i te UV me te makuku.
Papa WPC tawhito, pērā i ngā kōtaha YDWPC YD150SH25, YD150RH30, YD150S20, YD150H30, YD150H25, YD142S10, YD140SH25, YD140S25, me te YD140RH25, he mea hanga mai i te muka rakau me te kirihou wera (he HDPE te nuinga) kāore he paparanga tiaki o waho. Ko te nui o te muka rakau — he 50-60% te taumaha — e whakarato ana i te pakari o te hanganga me te ahua rakau tūturu, engari ka mimiti tika hoki i te hihi UV ki te mata o te papa. I roto i ngā āhuatanga UV werawera (taurangi UV 10-12+ puta noa i te tau), ka tere ake te pirau o ngā muka rakau mata i te hanganga polymer, ka hanga he taratara moroiti e tere ake ai te mimiti makuku me te ahotea huringa wera.
Ka pania e te paparanga WPC i whakapūtāhia ngātahitia he paparanga taupoki polymer ki runga i te matua hiato mā te tukanga whakapūtātanga i te wā kotahi — ka honoa te matua me te taupoki i roto i te haerenga kotahi, kāore e whakakikoruatia i muri i te mutunga. Ka whakaputahia e te raina whakaputa-tahi YDWPC ngā kōtaha YD140RH23 (140mm te whānui × 23mm te teitei) me te YD140S23 me te anga pūmua whakaputa-tahi 360° e kapi ana i te matua i ngā mata e whā. E toru ngā mahi a tēnei paparanga taupoki — he HDPE, he ASA rānei kua whakarerekētia — i roto i ngā āhuatanga werawera:
- Parenga UV: Ka mimiti te taupoki i te hihi UV, ka whakaata hoki i mua i te taenga atu ki te pūtake muka rakau, ka whakaiti i te pirau o te mata me te pakaru iti e tere ake ai te nekehanga wera. E ai ki ngā whakamātautau rauemi i roto i te EN 15534-4, ka mau tonu te kaha piko taketake o ngā papa i whakapūtāhia ngātahitia ki te 85-90% i muri i te 2,000 hāora o te whakawāteatanga UV tere, ki te whakaritea ki te 65-75% mō ngā kōtaha kore-taupoki tawhito.
- Ārai makuku: Ko te tere mimiti wai o te taupoki polymer he
- Te pakeke o te mata me te ātete paheke: Ka taea te hanga i te hanganga pūmua o te paparanga taupoki kia nui ake te mārō o te mata (Shore D 65-75) i te mea matua (Shore D 55-60), e whakapai ake ana i te ātete paheke — he whakaritenga haumaru nui mō ngā papa taha puna kaukau me te papa moana i ngā kaupapa hararei me ngā kaupapa arumoni kei reira tonu ngā āhuatanga mākū.
Mō ngā kaituku e arotake ana i te WPC co-extruded vs. classic mō ngā mākete pārūrū, Ko te painga o te whakatakotoranga o te whakakotahitanga ehara i te ātete UV anake — engari ko te pānga whakakotahi o te iti o te pirau UV, te iti o te mimiti makuku, me te iti o te horapa wera, ā, ka whakaitihia katoatia e ēnei te nui o te nekehanga me uru atu e te whakatakotoranga āputa. Ahakoa he kōwhiringa utu-pai tonu ngā kōtaha WPC tawhito mō ngā whakaurunga pārūrū kua hipokina, kua marumaru rānei (ngā whakamahau, ngā pergola, ngā ara hikoi kua hipokina), ko ngā papa pārūrū tuwhera - te taha puna kaukau, te tuanui, te ara hikoi papa, te marina - ka whai hua nui mai i te tiakitanga o te taupoki kua whakapūtāhia.
| Whakatakotoranga | Te Whakaputa-Ngātahi (YD140RH23 / YD140S23) | Matarohia (9 tauira, 140-150mm te whānui) |
|---|---|---|
| Whānui o te papa | 140mm | 140-150mm |
| Teitei o te papa | 23mm | 10-30mm (e whakawhirinaki ana ki te tauira) |
| Paparanga taupoki | Anga pūmua whakakotahi-360° | Kāore he taupoki) |
| Ātete UV (EN 15534-4) | I mau tonu te kaha piko o te 85-90% i muri i te 2,000 hāora | 65-75% te kaha piko i mau tonu i muri i te 2,000 hāora |
| Te mimiti wai (rumi 24 hāora) | 2-4% | |
| Pūtāhui | 15-25 tau | 10-15 tau |
| Te whakamahinga pārūrū e taunakitia ana | Te wāhi tuwhera: taha puna kaukau, tuanui, ara hīkoi, marina | Kua taupokina/kua marumaru: whakamahau, pergola, ara hīkoi |
| Ngā āhuatanga matua | Ārai wai, ārai makuku, ārai harore, ārai pepeke, ārai pakaru, ārai paheke, ārai waikura | Ārai wai, ātete makuku, ātete harore, ātete pepeke, ātete waikura, iti te tiaki |
Me mōhio ngā kaituku e mahi ana ki ngā mākete toropika, ko te whānui whaiti ake o ngā kōtaha whakaputa-tahi (140mm te whānui mō te nuinga o ngā tauira tawhito, ki te 150mm), he iti ake ngā mita rārangi o te āputa whānui mō ia mita tapawha o te papa kua tāutahia — he pai te tāutanga ina inehia ina utua ana ngā utu mō ngā kaupapa arumoni nui.
Whakatakotoranga Āputa Whānui: Ngā Mea e Hiahiatia ana e ngā Kaituku mai i ngā Kaihanga
Ehara te whakatakotoranga o te āputa whānui i te mea kotahi te tau e tika ana mō te katoa — engari me whai taunakitanga kua tuhia, kua tautokona e te kaihanga, e whai whakaaro ana ki te roa o te papa, te takotoranga, te tae, me ngā āhuatanga o te rangi o te rohe. Ko ngā kaituku e whakaae ana ki te reo whānui "waiho he āputa iti" i roto i ngā aratohu tāutanga, kei te whakarite i a rātou anō mō ngā tautohe pūtāhui me ngā karangatanga whakahoki a ngā kairīhi. Anei te anga whakatakotoranga e taunakihia ana e tā mātou tīma mō ngā kaupapa WPC pārūrū.
Hipanga 1: Tonoa te uara tauwehenga whānuitanga raina (CLTE) kua whakaputaina e te kaihanga, kua whakamatautauria mō ia ASTM D7032 rānei I roto i te 15534. Koinei te tau taketake — e whakaatu ana i te nui o te nekehanga o te papa i ia nekehanga o te huringa pāmahana, i ia waeine roa. Ko te kaihanga kāore e taea te whakaputa i te uara CLTE kua whakamatautauria ki tētahi paerewa kua whakaaetia, kāore e tohu ana; kei te whakaaro noa rātou. Mō te papa WPC, ko ngā uara CLTE kei waenganui i te 3.0 × 10⁻⁵ /°C (he nui te muka rakau, he mea whakaputa tahi) ki te 5.5 × 10⁻⁵ /°C (he nui te polymer, kāore i te taupokina). Ko te rerekētanga i waenga i ēnei uara e rua, e whakamahia ana ki tētahi papa 3.6m i runga i te nekehanga pāmahana 30°C, ko te rerekētanga i waenga i te 3.2mm me te 5.9mm o te nekehanga — tata ki te rua.
Hipanga 2: Tātaihia te awhe nekehanga e tumanakohia ana mō te roa o te papa, te tae, me te rohe āhuarangi. Ka nui ake te hihi o te rā ka mimitihia e ngā papa pouri, ā, ka eke ki ngā pāmahana teitei ake o te mata — ka taea e te papa WPC nati pango i raro i te rā toropika te eke ki te 70-75°C i te mata, ko te papa hina mārama ia ka eke ki te 55-60°C. Ko te rerekētanga pāmahana o te mata 15°C ka huri ki te 40% te nekenekehanga wera ake mō te papa pouri. Mō te papa pouri 3.6m te roa i Singapore (te pāmahana tāutanga noa 30°C, te pāmahana mata tihi 70°C, CLTE 3.5 × 10⁻⁵ /°C): ko te nekehanga roa e tumanakohia ana = 3,600mm × 40°C × 3.5 × 10⁻⁵ = 5.04mm. Koinei te tau me mimiti e te whakatakotoranga āputa — ā, me tuhi ki roto i te aratohu tāutanga a te kaihanga, me te tikanga tatau motuhake e kitea ana.
Hipanga 3: Manatokohia kei te whakaratohia e te kaihanga ngā whakaritenga mō te āputa pito (te hononga papa) me te āputa taha, kaua ko tētahi anake. Ko te nuinga o ngā hapa o te tāutanga WPC i ngā mākete toropika e pā ana ki ngā āputa pito — arā, ngā hononga e tūtaki ai ngā papa e rua i tō rāua roa. Ka neke hoki ngā āputa taha (i waenganui i ngā papa whakarara e rere ana i te ahunga kotahi), engari ka mimitihia e te pūnaha topenga huna ētahi o tēnei nekehanga mā te ngāwari o te topenga. Kāore he ārai pēnei i ngā āputa pito — me tohu me te pupuri tika. Ko te taunakitanga a tā mātou tīma kia whakarite kia whakaatuhia ngā whakatakotoranga āputa pito hei awhe (iti ki te mōrahi) i runga i te roa o te papa me te rerekētanga pāmahana ā-rohe, kaua hei tau kotahi kua whakaritea.
Hipanga 4: Whakaūtia kei te whai whakaaro ngā whakatakotoranga ki te awhe pāmahana katoa o te tāutanga — kaua ko te pāmahana hau taiao anake. Ko tētahi hapa whakatakotoranga noa ko te whakatakoto i te tatau āputa ki te pāmahana hau i te wā tāutanga (hei tauira, 28°C i te ata i Bangkok). Ko te tau e tika ana ko te pāmahana o te papa i te wā tāutanga, ā, i te rā tika ka taea te 10-15°C teitei ake i te hau taiao. Mena ka whakatakotohia e te kaiwhakauru ngā āputa i runga i te pāmahana tāutanga 28°C engari ko te papa kei te 40°C i te mata, ka kōpiri te papa ina mātao i taua ahiahi — ka waiho ngā āputa kia whānui ake i te mea kua tohua. Me tohutohu ngā kaihanga ki ngā kaiwhakauru kia whakahāngai ngā papa ki te pāmahana taiao i roto i te atarangi i mua i te ine me te whakatakoto i ngā āputa, me te tuhi hoki i tēnei whakaritenga ki roto i tā rātou aratohu tāutanga.
Ahakoa i hangaia ngā hua YDWPC mō te pumau o ngā āhuatanga, ko ngā whakaritenga motuhake mō te āputa whānui ka whakawhirinaki ki ngā āhuatanga o te rangi o te rohe, te aronga tāutanga, me te roa o te papa. Tirohia te aratohu tāutanga a te kaihanga mō ngā taunakitanga motuhake mō te kaupapa. Ka taea e ngā kaituku te tono i ngā pepa raraunga tāutanga motuhake a te YDWPC mā te whakapā atu ki tā mātou tīma kaweake, tae atu ki te tauira papa, te roa o te papa, te tae o te papa, te wāhi tāutanga, me te aronga tāutanga (whakarara, poutū rānei ki te tuaka roa o te hanganga).
Ngā Whakaaro mō te Whakamau me te Anga-iti mō ngā Papa WPC Tropical
Kāore e taea e ngā āputa anake te whakaoti i te whānui o te whenua — me uru te pūnaha whakapiri me te anga iti ki te nekehanga me te kore e ātete ki taua mea. Kāore he painga o tētahi āputa whakawhanui kua tohua tika mēnā ka tino piri te whakapiri ki te papa, ā, kāore e taea te neke. Ko ngā taunakitanga a tā mātou tīma mō te whakapiri WPC pārūrū koia ēnei:
- Ngā pūnaha topenga huna i runga i te whakawiri mata. Mā ngā topenga huna ka taea e te papa te reti whakaroa i te taha o te reera topenga i te wā e whānui ana, e whakawhāiti ana hoki. Mā te whakawiri-kanohi — arā, te pana i ngā topenga mā roto i te mata o te papa ki roto i te hononga — ka hangaia he pūwāhi pumau e ātete ana i te nekehanga, ā, ka puta he kukū ahotea ki te kōhao o ngā topenga. Mō ngā whakaurunga werawera me te huringa wera o ia rā, ka whakaitihia e ngā topenga huna te mōrearea o te kume a te topenga me te pakaru o te papa i ngā pūwāhi whakapiri.
- He kowiri tira, he maitai waro pania rānei ngā here. Ka tere ake te waikura o ngā here maitai waro kāore i tiakina e te haumākū pārūrū (70-90% RH puta noa i te tau). Ka whānui haere ngā here waikura (te whakapūtanga waikura), ka pakaru te papa WPC huri noa i te kōhao here. Tohua ngā tīwiri maitai kore waikura A2 (304) A4 rānei (316) mō ngā kaupapa moana me te takutai moana pārūrū, te maitai waro pania ki te Geomet® rānei mō ngā kaupapa o uta. Ko te waikura o ngā whakapiripiri te utu huna matua i roto i ngā tāutanga WPC werawera — kāore e puta i te utu tuatahi engari ka akiaki i ngā kereme whakamana 3-5 tau i muri i te tāutanga.
- Ngā anga raro rakau kua tukatukahia, ngā anga konumohe rānei. Ka pirau ngā kurupae rakau kāore i rongoatia i roto i te haumākū pārūrū i roto i ngā tau 2-3, ka ngaro te mau o ngā whakapiri, ā, ka taea te nekeneke haere o te papa i runga i te kore e taea te matapae. Tauwhāitihia ngā rakau kua rongoatia ki te CCA, ki te ACQ rānei (H3.2, neke atu rānei mō ia te tiaki rakau (ngā paerewa) me ngā kōtaha kurupae konumohe hei pupuri i te roa o te anga raro kore-pirau. Ka whakakorehia hoki e ngā anga raro konumohe te pānga ārai-makuku o te rakau, e māmā ake ai te tatau i te āputa whānui mā te tango i tētahi taurangi mai i te whārite.
He pūnaha te papa WPC pārūrū — he papa, he āputa, he whakapiri, me te anga iti — ā, mā te tohu takitahi i tētahi huānga ka puta he whakapono teka. Ko ngā kaituku e tuku ana i ngā wāhanga e whā hei pūnaha ōrite, ka puta he hua kaupapa pai ake, he iti ake hoki ngā kereme whakamana i ērā e hoko ana i ngā papa anake, ā, ka waiho mā te kaiwhakatū te kōwhiringa o te whakapiri me te anga iti.
Te Whakatutukitanga me te Tiwhikete Ture: Ngā Mea e Tika Ana kia Hiahiatia e ngā Rangatira Kaupapa Tropical
Waehere hanga whare he rerekē te hanganga ture mō te papa WPC i ngā mākete toropika i ia whenua, engari ko ngā anga whakamātautau e rua e mōhiotia ana i te ao — I roto i te 15534 (Pākehā) me ASTM D7032 (Amerika ki te Raki) — whakarato i te tūāpapa whakatakotoranga e tohutorohia ana, e whakaaetia ana rānei e te nuinga o ngā waehere ā-motu. Me manatoko e ngā kaituku e mahi ana ki ngā mākete kaweake pārūrū kua whakamatautauria ngā hua a tā rātou kaiwhakarato WPC ki te iti rawa i te kotahi o ēnei paerewa, me ngā pūrongo whakamātautau mai i ngā taiwhanga whai mana.
Mō ngā papa WPC e whakamahia ana mō ngā kaupapa pārūrū, ko ngā wāhanga whakamātautau tino nui e pā ana ki ngā whakaritenga ko:
- EN 15534-1 / ASTM D7032 — Te kaha piko me te tauwehenga: E whakaū ana ka taea e te papa te tautoko i ngā kawenga hoahoa (ko te nuinga he 2.0 kN te kawenga pūwāhi mō ngā whare noho, 4.0 kN mō ngā arumoni) me te kore e hurihanga tuturu. I roto i ngā whakaurunga werawera e pāngia ana e te huringa wera o ia rā, me whakamātautau ngā āhuatanga piko i te pāmahana teitei (40°C, neke atu rānei) kia whakaata i ngā āhuatanga o te ao tūturu.
- EN 15534-4 — Te tere o te huarere: Te pānga o te hihi UV, te rehu wai, me te huringa tio-rewa (te huringa haumākū rite ki te toropika). Ka ine tika tēnei whakamātautau i te ātete o te papa ki te pirau o te mata e akiaki ana i ngā huringa whanonga whānui mō te wā roa.

Ngā Pātai Auau
P1. Kia pēhea te whānui o te papa WPC i ngā āhuarangi pārūrū?
I ngā āhuarangi pārūrū, ka whānui te papa WPC mā te 2-6mm mō ia 3.6m te roa o te papa i te huringa wera o ia rā, i runga i te tae o te papa, te hanganga rauemi, me te pāmahana o te mata. Ko te tatau whānui e whakawhirinaki ana ki te tauwehenga whānui raina o te papa (CLTE), te rerekētanga pāmahana i waenga i te tāutanga me te pāmahana mata tihi, me te roa o te papa. Hei tauira, ko te papa pouri 3.6m te roa kua whakauruhia ki te 30°C, ā, ka eke ki te pāmahana mata 65°C (rerekētanga 35°C) me te CLTE o te 3.5 × 10⁻⁵ /°C ka whānui ake i te 4.4mm i tōna roa. Ko ngā papa mārama ake ka kite pea i te 20-30% te iti iho o te whānui nā te iti o te mimiti o te rā. Ka whakaputa a YDWPC i ngā uara CLTE mō ngā kōtaha papa katoa — whakapā atu ki tā mātou tīma kaweake mō te tautoko tatau motuhake mō te kaupapa.
P2. He pai ake ngā papa WPC i whakapūtāhia tahitia i ngā papa WPC tawhito mō ngā whakaurunga pārūrū?
Mō ngā whakaurunga werawera tuwhera (te taha o te puna kaukau, te tuanui, te ara hikoi, te marina), ka tukuna e ngā papa WPC kua whakakotahihia te mahi roa ake nā te paparanga potae polymer ārai-UV, e whakaiti ana i te pirau o te mata, te mimiti makuku, me te nui o te whānui wera. Ko te taupoki 360° i whakapūtāhia ngātahitia i runga i ngā kōtaha YDWPC YD140RH23 me YD140S23 e whakarato ana i te
P3. He aha te rerekētanga i waenga i te papa WPC tawhito me te papa WPC i hangaia tahitia?
Ko te paparanga WPC kua whakakotahihia he paparanga potae polymer tiaki kua honoa ki runga i te matua hiato i te wā e hangaia ana, ko te paparanga WPC matarohia he mea whakakotahihia mai i te muka rakau me te kirihou wera. Ko te paparanga taupoki — i whakamahia mā te whakaputanga i te wā kotahi (te whakakotahitanga) tukanga — ka tiakina te matua mai i te hihi UV, te urunga mai o te makuku, me te poke o te mata. Ko ngā kōtaha WPC tawhito (pēnei i te YDWPC YD150SH25, YD150RH30, me ētahi atu tauira i roto i te whānuitanga 140-150mm) e whakarato ana i te mahi hanganga tino pai mō ngā whakaurunga kua hipokina, ā, e wātea ana i roto i te whānuitanga o ngā ine kōtaha (10-30mm te teitei). Ko ngā kōtaha whakakotahi-whakaputa (YDWPC YD140RH23, YD140S23) kua arotauhia mō ngā tono o waho e kitea ana i reira te ātete UV, te mahi ārai makuku, me te pupuri tae mō te wā roa he mea nui ki ngā whakaritenga.
P4. Me whai hononga motuhake ngā papa WPC i ngā āhuarangi pārūrū?
Ae — ka tere ake te waikura o te whakapiripiri i te haumākū pārūrū, ā, me whai pūnaha whakapiripiri e urutau ana ki te nekehanga o te papa me te kore e ātete ki te huringa wera o ia rā. Tauwhāitihia ngā topenga huna kowiri tira A2 (304) A4 rānei (316) mō ngā kaupapa moana me ngā kaupapa takutai moana pārūrū, ngā topenga waro pania-teitei rānei mō ngā kaupapa uta. He pai ake ngā pūnaha topenga huna i te whakawiri-kanohi mō ngā whakaurunga pārūrū nā te mea ka taea e te papa te paheke roa i te wā e whānui ana te wera me te whakaheke. Ka whānui te rōrahi o ngā whakapiri waikura (te whakakoi waikura), ka pakaru te papa WPC huri noa i te kōhao whakapiri - he momo rahunga e puta ana i te 3-5 tau i muri i te whakaurunga, ā, he maha ngā wā ka hē te whakapae ki te kounga o te papa, kaua ki te kōwhiringa whakapiri. E taunaki ana a YDWPC i ngā pūnaha whakapiri motuhake mō ia kōtaha papa - whakapā atu ki tā mātou tīma kaweake mō ngā whakaritenga hototahi.
Q5. He aha ngā tiwhikete me rapu e au ina rapu ana au i ngā papa WPC mō ngā kaupapa kaweake pārūrū?
Ko ngā anga whakamātautau WPC e rua e mōhiotia ana i te ao ko I roto i te 15534 (te paerewa Pākehā e kapi ana i ngā āhuatanga ā-pūkaha, te pumau o ngā āhuatanga, me te ātete ki te huarere) me ASTM D7032 (Te paerewa o Amerika Te Raki mō te aromatawai i te mahi a te rakau hiato). Mō ngā kaupapa pārūrū, tonoa ngā pūrongo whakamātautau e kapi ana i: (1) te kaha piko i te pāmahana teitei (40°C+), (2) te tere o te huarere UV e ai ki te EN 15534-4, (3) te mimiti wai e ai ki te EN 15534-1, me te (4) te ātete paheke e ai ki te EN 13845, BS 7976-2 rānei. Hei tāpiri, manatokohia kei te mahi te kaihanga i raro i te ISO 9001 te whakahaere kounga — kāore tēnei e whakamana i te mahi a te hua, engari e whakaū ana kua tuhia, kua arotakehia, ā, kua rite tonu ngā tukanga hanga. Ka hangaia ngā hua YDWPC i raro i te ISO 9001, ā, ka whakamatautauria kia rite ki ngā paerewa o te ao e tika ana. Kei te wātea ngā pūrongo tohu CE me ngā whakamātautau taiwhanga whaimana mō ngā kaupapa kaweake ina tonoa.
P6. Ka taea te tāuta tika i te papa WPC ki runga i te raima i ngā āhuarangi pārūrū?
Ka taea te tāuta i te papa WPC ki runga i ngā papa raima i ngā āhuarangi pārūrū mā te whakamahi i ngā pūnaha turanga, i ngā pūnaha papa rānei, engari kāore i te tūtohutia te whakairi tika ki te mata me te kore he āputa waikeri. Ka puta te ua pārūrū (he maha ngā wā 1,500-3,000mm ia tau) hei hanga i te makuku e tū ana i raro i te papa e hiahia ana kia rere noa. Mā te turanga teitei, mā te pūnaha papa rānei e hanga he āputa hau 25-50mm i waenganui i ngā papa WPC me te papa raima, ka taea ai te rere o te wai me te rere o te hau e whakaiti ana i te hanga makuku me te mōrearea o te harore. Papa Ko te tikanga pai rawa atu mō te hanga i roto i ngā āhuarangi pārūrū me whai i te iti rawa o te 1-2% o te pari i runga i te papa raima hei arahi i te wai ki ngā pūwāhi rerenga wai. Mō ngā whakaurunga tuanui kei reira te papa raima e mahi ana hei kiriuhi ātete wai, ka tohatohahia e ngā pūnaha turanga te kawenga kia ōrite, ā, ka ārai i te kino o te utaina ki te kiriuhi. Ka taea e YDWPC te taunaki i ngā pūnaha turanga me ngā anga iti hototahi mō ngā whakaritenga kaupapa motuhake.
