He aha te Hangarau Taupoki ASA, ā, he aha te hiranga mō te Papa WPC?
Ko te ASA, Acrylonitrile Styrene Acrylate rānei, he kirihou wera ā-huarere kua noho hei rauemi taupoki matua i roto i te umanga papa rakau-kirihou o te ao. He rerekē ki ngā taupoki ABS, PVC rānei paerewa, he ātete pai rawa atu tā te ASA ki te hihi ultraviolet, te koroheketanga wera, me te pānga matū. Ina kōrero ngā kaihanga mō te "anga polymer tiaki" "paparanga taupoki" rānei i runga i te papa WPC, kei te whakaahua rātou i tētahi matū ASA e whakamahia ana i te wā o te tukanga whakakotahi. Ko te kupu "taupoki ASA" te ingoa paerewa o te ahumahi e mōhiotia ana e ngā kaipūtaiao rauemi, ngā taiwhanga whakamātautau, me ngā tohunga hokohoko puta noa i te ao.
Ko te hiranga o te hangarau taupoki ASA kei roto i tōna hanganga ngota. Ka mimiti te wāhanga acrylate i roto i te copolymer ASA, ka whakamarara hoki i te pūngao UV, me te kore e pāngia e ngā tauhohenga mekameka-wāhanga e whakangaro ana i ngā polymer iti iho. Ko te tikanga o tēnei, kāore te paparanga taupoki e pakarukaru, e kirikiri, e memeha rānei te tae ahakoa i muri i te roa o te wā e pāngia ana e te rā kaha. Mō ngā kaihoko B2B e arotake ana i ngā whakatakotoranga papa WPC, ko te mārama ko te rauemi taupoki he ASA, ehara i te anga polymer whānui, he pūtake nui mō te whakataurite i ngā hua puta noa i ngā kaiwhakarato. Ko te papa e hokohokohia ana he "capped" he "co-extruded" rānei, me te kore e tohua te rauemi taupoki, tera pea ka whakamahia he matū iti iho e kore e taea te tuku i te mahi roa rite tonu.
Hei tohutoro, ko te Papa tākai-tahi Ydwpc Ko te raina hua, tae atu ki te kōtaha YD140RH23, e whakamahi ana i tētahi anga polymer tiaki i hangaia kia tino tika, e mahi ana hei paparanga taupoki rite ki te ASA. Kua hangaia tēnei rauemi hei whakatutuki i ngā whakaritenga nui o ngā mākete kaweake puta noa i Ūropi, Amerika Te Raki, Āhia ki te Tonga-mā-rāwhiti, me te Waenganui Rawhiti, kei reira ngā paerewa ture me ngā tumanakohanga a te kaiwhakamahi mutunga mō te roa o waho.
Te Mārama ki te Whakakī 360-Tohu: He Whakamārama mō te Tiakitanga Mata Katoa
Ko te whakakāpōtanga 360-tohu e pā ana ki te tikanga hanga e karapotia katoatia ana e te paparanga taupoki ASA te matua WPC i runga i ngā mata katoa. Ko te tikanga o tēnei ko te mata o runga, te mata o raro, te taha maui, te taha matau, me ngā awaawa roa e rua o te papa kua hipokina katoatia e te rauemi taupoki tiaki. He whanaketanga nui tēnei i ngā tikanga whakakotahi-tahi o mua i whakamahia ai te rauemi taupoki ki te mata hikoi o runga anake, ka waiho te taha o raro me ngā taha kia kitea ki te urunga makuku, te whakahekenga UV, me te whakaekenga koiora.
Ko te tukanga whakaputa-tahi tonu e uru ana ki ngā whakaputa-tahi e rua e tukutahi ana. Ka hangaia e te whakaputa-tahi tuatahi te matua WPC mai i tētahi ranunga o te paraoa rakau, te polyethylene, te polypropylene rānei, me ngā tāpiringa tukatuka. Ka whakamahia ngātahitia e te whakaputa-tahi tuarua te ranunga taupoki ASA rewa huri noa i te matua i a ia e haere ana i roto i te mate. Mā te taputapu tika ka whakarite kia rite te matotoru o te taupoki, mai i te 0.3 ki te 0.7 mirimita, ki ia mata. Ko te hua he papa kotahi e honoa ana te taupoki me te matua ki te wera i te taumata ngota, ka hangaia he atanga maeneene e ātete ana ki te wehewehe i raro i te huringa wera, te ahotea miihini, me te roa o te wā e pāngia ana e te makuku.
He aha te hiranga o te whakakīkī 360-tohu katoa mō te hokohoko pakihi-pākihi? Whakaarohia he papa papa e tāutahia ana ki runga i te pūnaha turanga i runga i te kiriuhi. Ka kitea te taha raro e te wera me te makuku kua mau. I runga i te papa paerewa me te taupoki kei te mata o runga anake, ka arahi tēnei whakaaturanga o raro ki te piko, te pupuhi, me te hinganga hanganga. Ka ātete te papa kua whakakīkīhia katoatia ki ēnei pānga nā te mea ko te taupoki ASA kei te mata o raro e mahi ana hei ārai makuku. Koinei te take e tohua ai e ngā kaihoahoa me ngā miihini kaupapa matua te whakakīkī 360-tohu hei whakaritenga taketake i roto i ā rātou rarangi rauemi papa, ā, he aha ngā hua pēnei i te Papa tākai-tahi YD140RH23 mai i Ydwpc kei te piki haere te whakahuahia i roto i ngā tono kaupapa puta noa i ngā whenua maha.
He papa Ydwpc co-extrusion me te taupoki ASA 360-tohu katoa mō ngā ara hīkoi o waho me ngā mahi hotera.
Ātete UV: Te Ārai a te Apa Taupoki ASA i te Pirau Whakaahua
Ko te hihi ultraviolet te tūmomo mōrearea nui rawa atu ki te taiao mō ngā rauemi papa o waho. Ko ngā hihi UV i roto i te awhe roangaru 290 ki te 400 nanometer he nui te kaha hei wawahi i ngā hononga matū i roto i ngā polymer me te lignin, ka tīmata i te rerenga o ngā tauhohenga pirau. I roto i ngā papa WPC kāore i te taupokina, he tino ngoikore te wāhanga paraoa rakau. Ka mimiti te lignin i te hihi UV ka pāngia e te photo-oxidation, ka puta he quinones me ētahi atu matū chromophoric e puta ai te hina me te horo o te mata e kitea ana i runga i te rakau kua tawhito me ngā papa WPC iti te kounga i roto i te kotahi ki te toru ngā wā.
Ka arohia tēnei raruraru e te paparanga taupoki ASA i tōna pūtake. Kei roto i te pūmua ASA ngā monomer acrylate me ngā rōpū mahi mimiti-UV kua hangaia. Ka hopukina e ēnei rōpū ngā photon UV e haere mai ana, ka hurihia ō rātou pūngao hei pūngao wera kore kino mā te tukanga tahuritanga ā-roto kore-whakangaro. Kāore te rauemi taupoki e pirau, e memeha rānei nā te mea he mea whakaora anō te tikanga tohatoha pūngao. He rerekē tēnei i ngā paninga UV e pania ana ki te mata, i ngā tāpiringa rānei e pau ana i te wā roa, ā, ka ngaro te whai huatanga i muri i te maha mutunga o ngā huringa whakaaturanga UV.
Mō ngā kaupapa i roto i ngā taiao UV-nui pērā i te Middle East, te tonga-mā-rāwhiti o Āhia, ngā wāhi teitei rānei, ko te whakatakotoranga ātete UV te inenga mahi tino nui. Ko te Ngā whakaritenga paerewa ASTM D7032 mō te papa WPC kei roto ngā whakaritenga mō te aromatawai i te mahi UV mā roto i ngā whakamātautau huarere tere. Ko ngā papa he taupoki ASA kua whakaritea tika ka eke ki runga ake i ngā papa kāore i te taupokina mā te tawhiti nui i roto i ēnei whakamātautau. E ai ki ngā rangahau i whakaputaina e te ngā hautaka whakahoronga pūmua i runga i te ScienceDirect, ka mau tonu ngā papa WPC kua taupokina ki te ASA i te neke atu i te 90 ōrau o te kaha tae taketake i muri i te 2000 hāora o te whakaterenga xenon-arc, ko ngā papa rite kāore i taupokina he maha ngā wā ka heke iho i te 60 ōrau.
Ātete ki te memeha me te pupuri tae i roto i te roanga o te ora ratonga
Ko te memeha o te tae te whakaaturanga tino kitea o te pirau o te hihi UV, ā, koinei te mea e tino pā tika ana ki te pai o te kaiwhakamahi ki ngā papa o waho. I roto i ngā tono arumoni pēnei i ngā ara hīkoi o ngā wāhi hararei, ngā papa o ngā wharekai, me ngā papa hīkoi tūmatanui, ko te memeha koretake o te papa, te ngaro rānei o tōna āhua taketake i roto i ngā tau e rua ki te toru, he tohu nui tēnei mō te ingoa me te nama pūtea mō te kaipupuri whenua. Mō ngā kaihoko me ngā kaituku B2B, ko te tohu i ngā papa ātete-mema ehara i te mea he hiahia hangarau noa iho engari he whakatau nui a te pakihi e pā ana ki te pupuri i ngā kiritaki me ngā kereme whakamana.
Ka tutuki i ngā papa WPC kua tāpirihia ki te taupoki ASA te pupuri tae pai rawa atu mā roto i ngā tikanga tautoko e rua. Tuatahi, ko te pumau UV ā-roto o te pūmua ASA ka ārai i te paparanga taupoki tonu mai i te kōwhai, te kirikiri, te mā rānei. Tuarua, ka mahi te paparanga taupoki hei ārai ā-tinana e ārai ana i te hihi UV kia kore e tae atu ki te matua WPC tae i raro. Ko te tikanga o tēnei parenga rua, ahakoa ngā tae tino matotoru pērā i te nati pango, te tīki, me te waro, ka mau tonu tō rātou āhua tirohanga mō ngā tau neke atu i te mea ka taea e ngā hua kāore i te taupoki, i ngā hua iti rānei te taupoki.
Ko te ine huringa tae Delta E, i inehia mō ia ASTM D2244 Te Mahi Paerewa mō te Tātai i ngā Ātete Tae me ngā Rerekētanga Tae, e whakarato ana i tētahi pūtake tauanga whaitake mō te aromatawai i te ātete ki te memeha. E kī ana ngā paearu ahumahi ko te uara Delta E i raro i te 5.0 i muri i te 2000 hāora o te tere o te huarere he tohu i te mahi arumoni e whakaaetia ana. Ko ngā hua Premium ASA-capped mai i ngā kaihanga rongonui pērā i a Ydwpc ka eke ki ngā uara Delta E i raro i te 3.0 i raro i ēnei tikanga. Mō ngā kaihoahoa me ngā kaiwhakahaere kaupapa e tohu ana i te papa mō ngā tono tirohanga teitei, ko te tono raraunga Delta E mai i te kaiwhakarato he mahi pai e wehewehe ana i ngā hua tino pai mai i ērā e kī ana i ngā kereme hokohoko kāore i te tautokona.
Ātete ki te paru: Te pupuri i te ma o ngā mata o te papa i ngā tono e nui ana te haere
I roto i ngā wāhi manaaki manuhiri, ratonga kai, me ngā taiao arumoni o waho, he maha ngā wā ka pāngia ngā mata o ngā papa e ngā matū poke tae atu ki te waina whero, te kawhe, te hinu tunu kai, te hinu ārai rā, te paru manu, me te harore. He hanganga pūwero tō te papa WPC kāore i te taupokina e mimiti wawe ana i ēnei matū, ka puta he tae koretake tuturu e kore e taea te tango mā ngā tikanga horoi paerewa. I roto i te wā, ka puta he āhua papaki kino nā te poke kua kohia, ka whakararu i te uara ataahua o te tāutanga, ā, me whakakapi wawe te papa.
Ka tino whakarerekē te paparanga taupoki ASA i tēnei āhuatanga. He kirihou whakamahana mata kati, kāore e pūwero te ASA, he iti te kaha o te mata. Ka piri ngā wai ki te mata, kaua e mimiti, ā, ka taea te tango i te nuinga o ngā matū poke mā te hopi horoi ngawari me te wai. He āhuatanga taketake tēnei o te matū o te rauemi, kaua ki te maimoatanga mata e memeha haere ana i te haereere me te horoi. Ka mau tonu te ātete paru o ngā papa taupoki ASA puta noa i te roanga o te oranga o te hua, e whakarato ana i te tiaki pumau mai i te tāutanga tae noa ki ngā tekau tau o te whakamahinga.
Mō ngā tohunga hokohoko e arotake ana i te papa WPC mō ngā kaupapa arumoni, me noho ngā raraunga whakamātautau ātete paru hei wāhanga paerewa o te kete whakatakotoranga. Paerewa EN 15534 mō ngā hiato rakau-kirihoukei roto ngā whakaritenga mō te aromatawai i te ātete ki te paru me te ngāwari ki te horoi. YdHua Wpcs, tae atu ki te YD140RH23 me tePapa whakairo 3D awhe, kua whakamatautauria, kua whakamanahia hoki ki ēnei paerewa, me te whakarite kia tautokona ngā kereme mahi e te manatoko taiwhanga motuhake, kaua e ngā kereme hokohoko ā-roto.
Ngā Wero Āhuarangi o te Waenganui Rawhiti mō ngā Rauemi Papa o Waho
Ko te Waenganui Rawhiti tētahi o ngā taiao mahi tino uaua mō ngā rauemi hanga whare o waho o te Ao. Ko ngā rohe takutai moana o te UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, me Oman e pāngia ana e te pāmahana raumati roa neke atu i te 50 nekehanga Celsius, ngā uara tohu UV e neke atu ana i te 11 i runga i te tauine, te iti rawa o te ua ā-tau, ā, muri iho ka puta mai ngā ua nui, me ngā matūriki onepu pai e haria ana e ngā hau. Ko ia o ēnei āhuatanga ka whakararu motuhake i ngā rauemi papa o waho, ā, ko te pānga ngātahi ka tere ake te pirau i tua atu i ngā mea e kitea ana i ngā āhuarangi mahana o Ūropi, o Amerika Te Raki rānei.
Ka puta te whānui me te huringa whakaheke wera i te pāmahana teitei, ka taea te whakapiko, te whakapū, me te wetewete i ngā hononga i roto i ngā papa WPC kāore i te pai te hanga. Ka rerekē te tauwehenga o te whānui wera mō ngā hiato rakau-kirihou i runga i te hanganga, engari ko ngā papa kāore he taupoki-paparanga tika he tino ngoikore nā te mea ka whakanuia te kore pumau o te āhua e te urunga o te makuku mā roto i ngā mata kāore i hiritia. Ka whakaitihia tēnei e te taupoki ASA 360-tohu mā te whakarato i tētahi ārai makuku tonu e whakau ana i te rauemi matua ki ngā rerekētanga o te makuku, ahakoa i roto i ngā taiao takutai moana e tāpirihia ana e te hau tote he āhua waikura ki te wero.
He āwangawanga motuhake te kirikiri onepu o te Rawhiti o Waenganui e warewarehia ana i roto i ngā whakaritenga papa o te ao. Ko ngā matūriki quartz pai e haria ana e te hau he kirikiri pumau e memeha haere ana i ngā mata e kitea ana. Ko ngā papa WPC kāore i te taupokina me ngā papa he rauemi taupoki ngohengohe ka whakawhanake i te kakano taratara, kirikiri i roto i te wā raumati kotahi. Ko te paparanga taupoki ASA, me tōna pakeke mata me te ātete ki te kirikiri, ka roa ake te pupuri i tōna mutunga maeneene. Mō ngā kaupapa hotera me ngā kaupapa manaaki manuhiri i te rohe e whakawhirinaki tika ana te wheako manuhiri ki te kounga pā o ngā mata ara hikoi, he mea nui tēnei rerekētanga mahi. Kua mahi a Ydwpc ki ngā mākete kaweake puta noa i te Rawhiti o Waenganui mō ngā tau, ā, kua hangaia ngā hua a te kamupene kia pono te mahi i raro i ēnei āhuatanga tino kino.
Te Whakataurite i te WPC ASA-Capped Co-Extruded ki ngā Huarahi Kāore i te Capped me te Huarahi Kotahi-Taha
E toru ngā momo hua e tukuna ana e te mākete papa WPC: ngā papa reanga tuatahi kāore i te taupokina, ngā papa taha kotahi kua taupokina, me ngā papa kua tāpirihia katoatia ki te taupoki ASA. He mea nui te mārama ki ngā rerekētanga mahi i waenga i ēnei momo mō ngā kaihoko B2B e hiahia ana ki te whakataurite i te utu tīmatanga me te uara huringa ora. Ko ngā papa WPC kāore i te taupokina ngā mea iti rawa te utu mō ia mita raina, engari he poto rawa te roa o te ratonga, he iti rawa te pupuri tae, ā, he nui rawa te kawenga tiaki. He pai tonu mō ngā tāutanga rangitahi, mō ngā kaupapa iti-taapiri rānei, ina kore te roa o te ataahua e aro nui ki te āwangawanga matua.
Ko ngā papa taupoki taha kotahi te tohu i te ara waenga. Ka pania he paparanga taupoki tiaki, he maha ngā wā he PVC te pūtake, kaua ko te ASA, ki te mata hikoi o runga anake. Ka whakapai ake tēnei i te ātete ki te UV me te paru i te mata e kitea ana, engari ka waiho te raro me ngā taha kia kore e tiakina. I roto i ngā āhuarangi he pānga UV ngawari me te haumākū iti, ka taea e ngā papa taupoki taha kotahi te whakarato i te mahi e tika ana. Heoi, kāore e ranea ana mō ngā kaupapa arumoni teitei-whakaritenga, inā koa i ngā rohe he tino kino ngā āhuatanga taiao. Ka noho ngoikore tonu te mata o raro kāore i taupokina ki te mimiti makuku, ā, ka taea e te atanga taupoki-matua i ngā taha o te papa te mahi hei miki makuku e whakararu ana i te hanganga katoa.
Ko ngā papa kua whakakotahihia katoatia me te taupoki ASA 360-tohu e tohu ana i te āhua o nāianei. He utu nui tā rātou e whakaata ana i te utu rauemi tāpiri me te uaua o te hanga, engari he pai ake te mahi puta noa i ngā inenga katoa e tika ana: te pupuri tae, te ātete ki te paru, te ātete ki te makuku, te pumau o ngā āhuatanga, me te roa o te ratonga. Mō ngā tohunga hoko e tohu ana i te papa mō ngā kaupapa manaaki manuhiri, arumoni, umanga rānei me te pae hoahoa 15-tau, neke atu rānei, ko te tātari utu huringa ora e pai ake ana ki ngā hua kua kapi katoa. Ko te tātaritanga ahumahi hiato mai i CompositesWorld e whakaū ana i tēnei ia, me te kite i te tere haere o te nekehanga o te ao ki te WPC utu nui kua whakakotahihia i roto i ngā hanganga arumoni.
