Te Whakatakotoranga WPC me te Whakatakotoranga Rākau Tuku Iho: He Tātaritanga Utu-Painga mō ngā Kaihanga Pakihi
Ngā Whakaaro Matua
- He 20-35% te utu tīmatanga mō te uhi whakakotahitanga WPC (whakakotahi rakau-kirihou) i te rakau ngohengohe kua rongoatia, engari he 60-75% te iti iho o ngā utu tiaki mō te huringa ora 20-tau.
- Mā te hangarau whakakotahi-whakaputa ka hangaia he anga pūmua tiaki huri noa i te matua WPC, e whakarato ana i te pumau o te UV, te ātete ki te makuku, me te pupuri tae e pai ake ana i te whakakikorua rakau pakeke kounga teitei.
- Kei te neke ngā kaihanga arumoni i Ūropi me Amerika Te Raki ki te whakakikorua WPC nā te mea ASTM D7032 ā, mā te hanganga ture EN 15534 ka māmā ake te whakaaetanga waehere hanga, ā, ka kore e hiahiatia te mahi tiaki tae me te hiri ā-tau e hiahiatia ana mō te whakakikorua rakau.
- Ko te utu katoa mō te pupuri i te whakakikorua WPC mō ngā tau 20 he 35-50% te iti iho i te utu rakau ina whakaarohia te whakakapinga rauemi, te mahi mō te whakahou, me ngā utu whakakorenga i te mutunga o te oranga.
Te Utu Tuturu o te Whakatakotoranga Rakau Kāore i Kōrerohia i te Wāhanga Tuku
Tekau tau kua pahure ake nei e āwhina ana ahau i ngā kawemai rauemi hanga i Ūropi, Amerika Te Raki, me Āhia ki te Tonga-mā-rāwhiti ki te rapu rauemi hanga. Papa Wpc, taiapa, me te whakakikorua mai i ngā wheketere Haina. He rite tonu te tīmatanga o te kōrero: kua tohua e te kaihoahoa te whakakikorua rakau (ko te nuinga he hita whero o te hauauru, he rēreti, he paina thermowood rānei), ka whakaritea e te kaiwhakatū he utu mō ngā rauemi me te tāutanga, ā, ka neke whakamua te kaupapa me te mea e ahua whai hua ana.
Kāore rawa i roto i te tono tuatahi te utu tiaki e kohia ana i ia tau i muri i te tāutanga. Me pania, me pania rānei te uhi rakau i ia 2-5 tau, i runga i te momo, te pānga, me te momo whakaotinga. I Ūropi ki te Raki, he nui te pānga o te ua, te huka, me te hihi UV, ka pau i te whare arumoni he 500 mita pūrua te rahi o te uhi rakau i te $3,000-6,000 mō ia huringa tiaki mō ngā tūāpapa, ngā mahi, me ngā rauemi — i ia 3 tau, mō te roanga o te oranga o te whare.
Ina whakaaturia e au ki ngā kaimahi kirimana me ngā kaipupuri whare he whakataurite utu mō te huringa ora 20-tau i waenga i te whakakikorua rakau tuku iho me te whakakikorua WPC co-extrusion, he pai tonu te WPC ki ngā tatauranga. Anei te mahi a taua tātaritanga.
He aha te WPC Co-Extrusion Cladding, ā, me pēhea te hanga?
Ko te WPC (whakakotahi rakau-kirihou) he rauemi hangarau i hangaia mai i te ranunga o te muka rakau (te nuinga o te wā he 50-60%), te polymer thermoplastic (HDPE, PP rānei, 30-35%), me ngā tāpiringa mahi (5-15%) tae atu ki ngā whakaū UV, ngā tae tae, ngā kaihoko hononga, me ngā patu harore. Ka whakamahanahia te ranunga, ka whakaranua, ka tukuna mā roto i te mata hei hanga papa me te wāhanga whakawhiti ōrite.
Ko te whakakotahitanga-tahi te ahunga whakamua nui e wehewehe ana i te whakakikorua WPC hou mai i ngā hua hiato o te whakatipuranga tuatahi. I roto i te tukanga whakaputa-tahi, ka pania e te kaiwhakaputa tuarua he paparanga taupoki polymer tiaki (he 0.3-0.7mm te matotoru) huri noa i te matua WPC i a ia e puta ana i te mate tuatahi. Ko tēnei paparanga taupoki — i hangaia ki ngā aukati UV kukū me ngā tae tae — ka hangaia he mata hiri e tiaki ana i te matua muka rakau mai i te urunga makuku me te pirau UV.
Ko te hua he papa whakakikorua e āhua rite ana ki te rakau tūturu (nā ngā tauira kōhatu whakairo i roto i te paparanga taupoki) engari he rite tonu te mahi ki te polymer mahi-teitei. Ko tā mātou Whakatakotoranga WPC tahi-whakaputa YD216H25 ka hangaia i runga i tētahi raina whakaputa-tahi aunoa me te aroturukitanga matotoru o te taupoki wā-tūturu hei whakarite i te tiakitanga ōrite puta noa i ia mita raina. Ka hangaia hoki e mātou ngā hua tāpiri - mō ngā kaupapa e hiahia ana ki tētahi kete o waho katoa, ko tā mātou Paepae taiapa WPC e whai hua ana i te hangarau whakaputa-tahi me te pūnaha taurite tae kotahi.
Whakataurite i ngā Utu mō te Huringa Ora 20-Tau: WPC me te Whakakikorua Rakau
| Kāwai Utu | Rākau Ngāwari i Whakaorahia (Paina/Rāka) | Rākau Mārō Kounga Rawa (Hita/Ipe) | WPC Co-Extrusion Covering |
|---|---|---|---|
| Te utu rauemi (m²) | $25-40 | $60-120 | $35-55 |
| Te utu tāutanga (m²) | $15-25 | $20-35 | $15-25 |
| Tapeke tuatahi (m²) | $40-65 | $80-155 | $50-80 |
| Te utu tiaki ā-tau (m²) | $3-6 (whakapaipai/hiri) | $2-4 (whakahinuhinu) | $0 (kāore he tiaki) |
| Te whakahounga nui (ia 5 tau, ia m²) | $8-15 | $5-10 | $0 |
| Whakakapinga papa (20 tau, 10% te horahanga) | $4-8 | $6-15 | $0-2 |
| TCO 20-Tau (m²) | $110-180 | $120-220 | $52-85 |
Nā te mea kāore he tiaki ā-tau e hiahiatia ana mō te hipoki WPC co-extrusion — kāore he tae, kāore he hiri, kāore he hinu — ko te utu katoa o te mana pupuri mō ngā tau 20 he 35-50% te iti iho i te rakau ngohengohe kua rongoatia, ā, he 55-65% te iti iho i te rakau mārō kounga teitei. Ka nui ake te whakaharahara o ēnei tatauranga ina whakaarohia te utu o ngā tūāpapa mō ngā whare arumoni maha-papa, ina koa ko te huringa tiaki kotahi ka eke ki te $10,000-20,000 te utu mō ngā taputapu urunga anake.
Whakataurite Mahi: Ātete ki te Makuku, te UV, me te Ātete ki ngā Pepeke
Mō ngā kaihanga arumoni, ko ngā inenga mahi tino hira ko te pumau o ngā āhuatanga i roto i te huringa makuku, te pupuri tae i raro i te hihi UV, me te ātete ki ngā whakaekenga koiora (ngā pepeke me ngā harore).
- Te mimiti makuku: Ka mimiti te papa rakau i te 12-25% o te makuku ina mākū, ka pupuhi, ka piko, ka takahuri. Ka mimiti te papa WPC co-extrusion i raro iho i te 1% o te makuku — ka hiritia e te paparanga taupoki polymer te matua muka rakau mai i te pa tika ki te wai. Ko te tikanga o tēnei ka mau tonu ngā papa WPC i ō rātou ātete ā-ahu i roto i te ua, te hukarere, me ngā huringa makuku me te kore e hiahiatia he āputa whānui me ngā whakapiri e hiahiatia ana e te papa rakau.
- Ātete UV: Ka pirau te rakau kāore i tiakina i raro i te hihi UV — ka pakaru te lignin i roto i te muka rakau, ka huri te mata ki te hina me te pōuriuri i roto i ngā marama 6-12 o te pānga. Ahakoa e mihi ana ētahi kaihoahoa ki tēnei āhuarangi taiao, ko ngā kaipupuri whare arumoni kāore e pai ki tēnei. Ka mau tonu te tae taketake o te uhi WPC co-extrusion mō ngā tau 15-25 nā te mea kei roto i te paparanga taupoki ngā whakaū UV kukū (ko te tikanga ko te HALS — ngā whakaū mārama amine āraihia — i te 2-4% utaina) e mimiti ana, e whakamarara ana hoki i te kaha UV i mua i te taenga ki te pūtake muka rakau.
- Ātete ki ngā pepeke me ngā harore: He ngoikore te uhi rakau ki ngā moko, ki ngā pītau rakau, me te pirau harore — inā koa i ngā āhuarangi mahana, makuku. Kei roto i te uhi WPC ngā tāpiringa patu harore me ngā patu pepeke kua konatunatua ki roto i te matū matua i te wā e hangaia ana, e whakarato ana i te tiaki koiora kua hangaia, me te kore he maimoatanga matū i muri i te hanga.
Te Mahi Ahi me te Whakatutuki i ngā Ture Hanga
He mea nui haere te whakatakotoranga o te mahi ahi mō ngā rauemi whakakikorua arumoni, inā koa i Ūropi whai muri i te aituā o te Grenfell Tower me te whakakaha ake i ngā ture hanga whare puta noa i te EU. Anei te tūnga o te whakakikorua WPC i roto i te whenua mahi ahi:
Ko te whakakikorua WPC paerewa (kāore he tāpiringa ārai ahi) ka eke ki te whakatauranga Akomanga C, Akomanga D rānei i raro i te pūnaha whakarōpūtanga ahi EN 13501-1 a Ūropi, e rite ana ki te tauhohenga ahi e rite ana ki te rakau matotoru-waenga. Mō ngā whare arumoni e hiahia ana ki te mahi ahi Akomanga B, kei te wātea ngā whakatakotoranga WPC ārai ahi e whakauru ana i ngā whakakī kohuke (konumohe trihydrate, konupora hauwai) i te 10-20% utaina.
Kua whakamatautauria tā mātou whakakikorua WPC me te hanganga ātete-ahi ki te EN 13501-1 Akomanga B-s1,d0, e tutuki ana i ngā whakaritenga mō ngā whare neke atu i te 18 mita te teitei i te nuinga o ngā mana whakahaere o Ūropi. Ka whakauruhia te tāpiri ātete ahi ki roto i te matū matua i te wā e hangaia ana — ehara i te mea he paninga mata ka memeha haere i roto i te wā. Ko te tikanga o tēnei he mea hanga tonu te mahi ahi ki te rauemi, ā, kāore e pirau i te wā e pāngia ana e te huarere.
Mō ngā kaupapa o Amerika Te Raki, me tutuki te whakakikorua WPC i te ASTM E84 (whakamātautau kauhanga Steiner) mō te horapa o te mura me te whanaketanga o te paowa. Ko ngā hanganga WPC paerewa ka eke ki te whakatauranga Akomanga A, Akomanga I rānei (taupū horapa mura 0-25, taupū whanaketanga paowa 0-450) ina whakamatautauria kia rite ki te ASTM E84.
Te Whai Hua o te Tāutanga: Me pēhea te Whakaiti a te WPC i ngā Utu Mahi i te Papa
Haunga te mahi a ngā rauemi, he maha ngā painga tāutanga o te whakakikorua WPC co-extrusion e whai hua ana ki te penapena utu mahi mō ngā kaupapa arumoni:
- Pūnaha topenga huna. Ka whakamahia e tā mātou whakakikorua YD216H25 he topenga kowiri tira huna e neke ana ki roto i te awaawa o roto o te papa. Kāore he whao mata, kāore he whakapiripiri e kitea ana, ā, ka mau tonu ia papa ki tētahi atu me te tawhiti ōrite. He 30-40% te tere ake o te tāutanga o tēnei pūnaha i te whakakikorua rakau mata-mau nā te mea kāore e hiahiatia e te kaiwhakauru te keri i mua, te totohu i te papa, te whakarite rānei i ngā whao takitahi.
- Kāore e hiahiatia he maimoatanga i mua. He maha ngā wā ka hiahiatia he hiri i te pito o te papa rakau, he whakakī i ngā pona, me te paninga i mua i te tāutanga. Kua rite ngā papa WPC ki te tāuta tika mai i te takai — tapahia kia rite te roa, kutikutihia, kātahi ka neke ki te papa e whai ake nei.
- Te manawanui āhua ōrite. Ko ngā papa WPC i whakaputahia mai i te wheketere e pupuri ana i ngā āheinga ā-ahu o te ±0.5mm puta noa i te whakahaerenga katoa. Ka rerekē pea te whānui me te matotoru o ngā papa rakau tūturu i waenga i ngā papa mā te 2-5mm, me te hiahia kia whakarōpūtia me te tīpakohia i te wāhi. Ko te tikanga o ngā ā-ahu WPC ōrite ko ngā hononga ōrite me te tāutanga tere, matapaetia.
- Mama ake te taumaha. Ko te taumaha o ngā papa whakakikorua WPC he tata ki te 2.0-2.5 kg ia mita rārangi (mō ngā papa 216mm te whānui), ki te whakaritea ki te 3.0-4.5 kg mō ngā papa rakau pakeke ōrite. Mā tēnei whakaiti taumaha ka whakaitihia te ngenge o te kaiwhakauru, ka māmā ake te mahi hanga tūāpapa, ā, ka whakaitihia te kawenga hanganga ki runga i te anga o te whare.
Ngā Whakaaro Hē Noa mō te WPC Cladding
I roto i aku wheako ki te āwhina i ngā kaituku ki te whakawhiti mai i te rakau ki te WPC, ka tūtaki tonu ahau ki ngā whakaaro hē kotahi. Mā te whakatika wawe i ēnei ka ārai i ngā hapa utu nui:
Whakaaro hē 1: "He āhua rūpahu te āhua o te WPC." He rite tonu te kakano o te WPC o te whakatipuranga tuatahi, ā, he auau tonu. Mā te whakamahi i te whakakotahitanga hou ka puta he tauira rakau whakairo hohonu me te rerekētanga tae tūturu. I te tawhiti tirohanga 3-5 mita (he tikanga mō ngā mata o mua), ahakoa ngā kaihanga mohio, kāore e taea te wehewehe i te WPC kounga mai i te rakau me te kore e pā atu. Ka whakamahia e tā mātou mahi he roera whakairo CNC me ngā tauira witi mai i ngā tauira rakau tūturu, ka puta he rerekētanga hohonu 0.5-0.8mm.
Whakaaro Hē 2: "He taumaha rawa te WPC mō te whakahou." I te 2.0-2.5 kg ia mita rārangi mō te papa 216mm te whānui, he mama ake te WPC i te nuinga o ngā papa rakau mārō. Ko te āwangawanga i ahu mai i te pōhēhētanga ki ngā papa papa hanganga. Kāore ngā papa papa he hanganga, ā, ka mahi tahi me ngā anga papa paerewa.
Whakaaro Hē 3: "Kāore e taea e WPC te whakahaere i ngā pihi." Ahakoa kāore e taea e te WPC te piko mātao pērā i te rakau angiangi, mā te hanga wera ka taea te hanga i ngā piko ngawari (te whānui neke atu i te 3-4 mita). Mō ngā piko kikī ake, ka taea e ngā kōtaha WPC ngāwari me ngā matua angiangi te whakauru i ngā radius ki raro ki te 2 mita ina werahia ki te 80-100 nekehanga C.
Nā te mea ka ārahi ēnei whakaaro hē i ngā kaihoahoa ki te whakakore i te WPC me te kore he aromatawai tika, ka tūtohu ahau kia whakaratohia he papa tauira ā-tinana mō ngā tauira kei te papaanga. Kia kite rā anō te kaihoahoa i tētahi tauira WPC 3x3 mita me te whakatakotoranga rakau, tata tonu ka pai ake te whakataurite i te WPC mō ngā tono arumoni.
Te Oranga Tonutanga me ngā Whakaaro Taiao
Mō ngā kaihanga arumoni e whai ana i ngā tiwhikete whare matomato (LEED, BREEAM, DGNB rānei), ka whai wāhi te whakakikorua WPC ki ētahi wāhanga nama:
- Ngā ihirangi hangarua. Kei roto i ngā papa WPC te 50-60% o te muka rakau (i ahu mai i ngā para rakau hangarua me ngā hua taha o te mira kani) me te 30-35% o te HDPE hangarua (kirihou hangarua muri-kaihoko). Ka āhei tēnei ōrau ihirangi hangarua mō te Whiwhinga LEED MR: Whakaaturanga Hua Hanga me te Arotau — Te Hoko Rauemi Mata.
- Kāore he rakau mārō toropika. Mā te whakamahi i te WPC hei utu mō te whakakikorua rakau mārō pārūrū (Ipe, Cumaru, Balau) ka whakakorea te pānga o te whakangaromanga ngahere me te kanorau koiora e pā ana ki te hauhake rakau pārūrū. E hangai ana tēnei ki ngā whiwhinga BREEAM MAT 03 (Responsible Sourcing).
- Te āheinga ki te hangarua i te mutunga o te oranga.Ka taea te huri i te paparanga WPC ka taea te whakaputa anō ki roto i te mea hou Hua Wpci te mutunga o te oranga — he rerekē ki te whakakikorua rakau kua rongoatia ki ngā mea tiaki, me maka atu hei para morearea i roto i te maha o ngā mana whakahaere.
Nā te mea he mea hanga te hipoki WPC mai i ngā awa para (muka rakau hangarua me te kirihou hangarua), ka aro atu ki ngā whakaritenga ōhanga porowhita e whakahauhia ana i roto i ngā whakaritenga hokohoko tūmatanui o Ūropi.
Ngā Pātai Auau
He pēhea te mahi a te uhi whakakotahi-ā-WPC i ngā āhuarangi tino makariri pērā i a Scandinavia?
He pai te mahi a te uhi whakakotahi-whakaputa WPC i te makariri rawa, nā te mea kāore te anga polymer e pakarukaru i ngā pāmahana i raro i te kore - ko te pāmahana whakawhiti karāhe o te here HDPE he tata ki te -120°C. Kua whakamatautauria tā mātou uhi mō te huringa tio-rewa e ai ki te EN 15534 (100 huringa mai i te -20°C ki te +20°C me te kore e kitea he pakaru, he piko, he wehewehe rānei). Ka mau tonu te mana o te paparanga taupoki mā te huringa wera, koinei te tikanga rahunga matua mō ngā hua WPC o te whakatipuranga tuatahi me te kore he whakakotahi-whakaputa. Me pupuri e ngā kaiwhakauru i ngā whenua Nordic he āputa whakawhānui 3-5mm i ngā pito o te papa hei whakauru i te nekehanga wera (ka whakawhānui te WPC tata ki te 1.5-2.0mm ia mita raina me te nekehanga pāmahana 30°C).
Ka taea te peita, te whakakoi rānei i te paparanga WPC kia rerekē te tae i muri i te tāutanga?
Ahakoa e taea ana e te paninga WPC te tango peita, te tae rānei, kāore au e tūtohu. He mea hanga motuhake te paparanga taupoki whakakotahi-whakaputa hei ātete i te piri o ngā paninga mata — koinei te take e kore ai e nui te tiaki. Kāore e piri pono te paninga peita, tae rānei ki te mata o te taupoki, ā, ka tihore i roto i te 1-2 tau. Mena e hiahia ana koe ki tētahi tae motuhake, tonoa te paninga i taua tae i te wā e hangaia ana. Kei roto i tā mātou whānuitanga tae paerewa e 8 ngā tauira rakau-kiko (ōki, nati, tīki, hita, waro, hina papa, rakau kua tawhito, me te paninga mā), ā, e wātea ana ngā tae ritenga mō ngā ota neke atu i te 5,000 mita pūrua.
He aha te whakatauranga ahi o te whakakikorua WPC paerewa kāore he tāpiringa ārai ahi?
Ko te whakakikorua WPC paerewa kāore he tāpiringa ārai ahi ka eke ki te whakatauranga Euroclass D-s1,d0, C-s1,d0 rānei i raro i te EN 13501-1, he rite ki te rakau ngohengohe kāore i te rongoatia. Mō ngā whare arumoni e hiahia ana ki ngā whakatauranga ahi teitei ake (Akomanga B, pai ake rānei), tohua tā mātou hanganga ārai ahi e eke ana ki te B-s1,d0. I Amerika Te Raki, ko te WPC paerewa ka eke ki te ASTM E84 Akomanga A (taupū horapa mura 0-25). Me manatoko tonu te pūrongo whakamātautau ahi mō te hua me te tae motuhake e tonoa ana e koe, nā te mea ka pāngia te mahi ahi e ngā tae me ngā hanganga paparanga taupoki.
Me pēhea te whakahaere a te whakakikorua WPC i ngā tipu koiora pērā i te pokepokea ai me te rimurimu?
He tino ātete te hipoki WPC co-extrusion ki te tipu koiora nā te mea kāore te paparanga taupoki polymer e whakarato i tētahi puna kai rauropi mō ngā pua harore, ngā pua rimurimu rānei. Heoi, i ngā wāhi marumaru, haukū tonu (ngā pakitara e anga ana ki te raki i ngā āhuarangi haukū), ka taea e te biofilm mata te puta ki runga i tētahi rauemi o waho. Mena ka puta tēnei, he rawaka te horoi ki te wai hopi ngawari me te paraihe ngohengohe - he rerekē ki te hipoki rakau, e hiahia ana kia rongoatia he matū me te oro anō hei tango i te harore kua mau. Ko ngā tāpiringa harore i roto i te matū matua WPC ka whakarato i tētahi atu paparanga tiaki mai i te pirau harore mena ka uru te makuku ki te taha tapahi, ki te karawarawa rānei.
He aha te pūtāhui e whakaratohia ana e Yida mō te whakakikorua WPC co-extrusion?
Ka whakaratohia e mātou he pūtāhui iti 15-tau e kapi ana i te hanganga pai, te memeha o te tae (iti iho i te 5 ngā waeine Delta E i roto i te wā pūtāhui), me te wehewehe i te paparanga taupoki whakakotahi. Ka whai mana te pūtāhui ina tāutahia te whakakikorua e ai ki tā mātou aratohu tāutanga (tae atu ki te hauhautanga tika, te whakapiri, me ngā whakaritenga āputa whānui) ā, kāore e kapi i ngā kino mai i te whakamahinga hē, te pānga, ngā whakarerekētanga kāore i whakamanahia rānei. Ka tukuna hoki e mātou ngā kōwhiringa pūtāhui roa 25-tau mō ngā kaupapa neke atu i te 10,000 mita pūrua. Ngā tuhinga pūtāhui katoa, tae atu ki ngā pūrongo whakamātautau mō ia ICC-ES me te EN 15534, e whakaratohia ana me ia uta.
