Hīkoi mā roto i tētahi papa hanga, pāmu, papa mahi rānei, ā, ka kite koe i ngā tāpaurin PVC e mahi kaha ana—e tiaki ana i ngā utanga mai i te ua, e hipoki ana i ngā pēke tarutaru mai i te kino o te rā, e hanga ana rānei i ngā piringa rangitahi. He aha te mea e roa ai ēnei hōiho mahi? Ehara i te mea ko te kapia PVC matotoru anake, ko ngā papa papanga kaha rānei—ko te whakau PVC e ārai ana i te rauemi kia kore e pakaru i raro i ngā āhuatanga kino o waho me te whakaputanga pāmahana teitei.
He rerekē tēnei i ngā hua PVC mō te whakamahi i roto i te whare (whakaarohia te papa vinyl, ngā panera pakitara rānei), he maha ngā āhuatanga taumaha e pā ana ki ngā tāpaera: te hihi UV tonu, te piki me te heke o te pāmahana (mai i te hotoke hukapapa ki te raumati wera), me te piko, te totoro rānei i ngā wā katoa. Kōwhiria te whakaū hē, ā, ka memeha, ka pakaru, ka tihore rānei ō tāpaera i roto i ngā marama—ka nui ake te utu mō ngā hokinga mai, ka maumauria ngā rauemi, ka ngaro hoki te whakawhirinaki o ngā kaihoko. Me whakamārama tātou me pēhea te whiriwhiri i tētahi whakaū e tutuki ai ngā hiahia o te tāpaera, me pēhea hoki e whakarerekē ai i tō tukanga whakaputa.
Tuatahi: He aha te mea e rerekē ai ngā tāpaurin?
I mua i te ruku ki ngā momo whakapūmau, he mea nui kia mārama koe ki ngā mea e hiahiatia ana e tō tāpaurinihi kia ora ai. Mō ngā kaihanga, e rua ngā mea e ārahi ana i ngā kōwhiringa whakapūmau:
• Te pakari o waho:Me ātete ngā tāpare ki te pakaru o te hihi UV, te mimiti wai, me te waikura. Ki te kore e tutuki te whakau i konei, ka pakarukaru, ka memeha te tae o ngā tāpare i mua noa atu i te roanga o te oranga e tumanakohia ana (e 2–5 tau te nuinga).
• Te ātete ki te whakaputanga:Ka hangaia ngā tāpaurin mā te whakatārewatanga i te PVC kia angiangi, mā te paninga rānei ki te papanga polyester/miro—ka whakahaerehia ngā tukanga e rua i te 170–200°C. Mā te ngoikore o te whakapūmau ka kōwhai te PVC, ka puta rānei he ira i waenganui o te hanga, ā, ka meinga koe kia para i ngā puranga katoa.
Me te maumahara ki aua hiahia, me titiro tātou ki ngā mea e tukuna ana e ngā whakaū—me te take hoki.
Te Mea Pai rawa atuNgā Whakapūmau PVCmō ngā Tarpaulin (me te wā hei whakamahi)
Kāore he momo whakaū "kotahi te rahi e pai ana mō te katoa" mō ngā tāpare, engari e toru ngā kōwhiringa e pai ake ana i ētahi atu i te hanga o te ao tūturu.
1,Ngā Whakakotahitanga Konupūmā-Konutea (Ca-Zn): Te Mea Katoa mō ngā Tāpare o Waho
Mena kei te hanga tāpare whānui koe mō te ahuwhenua, mō te rokiroki rānei i waho,Ngā whakaū hiato Ca-Znkoinei te mea pai rawa atu. Anei te take i noho ai rātou hei mea nui i te wheketere:
• Kāore he mata, ko te tikanga ka taea e koe te hoko i ō tāpare ki ngā mākete o te EU me te US me te kore e manukanuka ki ngā whiu REACH, CPSC rānei. Kāore ngā kaihoko i ēnei rā e pā ki ngā tāpare i hangaia ki ngā tote mata—ahakoa he iti ake te utu.
• He pai te whakamahi i ngā tāpiringa UV. Whakaranua he 1.2–2% te whakau Ca-Zn (i runga i te taumaha o te kapia PVC) me te 0.3–0.5% ngā whakau mārama amine ārai (HALS), ā, ka rua, ka toru rānei te ātete UV o tō tāpa. Nō nā tata nei ka huri tētahi pāmu i Iowa ki tēnei ranunga, ā, i kīia e whā tau te roa o te mau o ā rātou tāpa tarutaru, kaua ki te kotahi tau.
• Ka pupuri i ngā tāpare kia ngāwari. Kāore i rite ki ngā whakaū pakari e whakamārō ana i te PVC, ka mahi tahi a Ca-Zn me ngā mea whakapūmau kirihou hei pupuri i te ngāwari o te takai—he mea nui mō ngā tāpare e hiahia ana kia pōkaihia, kia rongoatia hoki ina kore e whakamahia.
Tohutohu ngaio:Kōwhiria te Ca-Zn wai mēnā kei te hanga koe i ngā tāpare māmā (pērā i ngā mea mō te puni). Ka whakaranua pai ake ki ngā mea whakapūmau kirihou i te paura, kia rite ai te ngāwari puta noa i te tāpare katoa.
2,Ngā Ranunga Pāriuma-Konutea (Ba-Zn): Mō ngā Tāpare Taumaha me te Wera Nui
Mena ko ngā tāpare taumaha tōu arotahi—ngā taupoki taraka, ngā whare tiaki ahumahi, ngā arai papa hanga rānei—Ngā mea whakaū Ba-Znhe pai te haumi. Ka tiaho ēnei ranunga ki ngā wāhi e tino wera ana, e tino taumaha ana hoki:
• He pai ake tā rātou whakahaere i te whakaputanga pāmahana teitei i te Ca-Zn. Ina pania te PVC matotoru (1.5mm+) ki runga i te papanga, ka ārai a Ba-Zn i te pirau wera ahakoa i te 200°C, ka tapahia ngā taha kōwhai me ngā hononga ngoikore. I whakaitihia e te kaihanga tāpaera kawe i Guangzhou ngā reiti para mai i te 12% ki te 4% i muri i te huri ki te Ba-Zn.
• Ka whakanui ake i te ātete ki te haehae. Tāpirihia he 1.5–2.5% Ba-Zn ki tō hanganga, ā, ka kaha ake te hononga o te PVC ki te paparanga papanga. He mea nui tēnei mō ngā tāpare taraka ka kumea kia piri ki runga i ngā utanga.
• He hototahi ēnei ki ngā ārai mura. He maha ngā tāpare ahumahi me tutuki i ngā paerewa haumaru ahi (pēnei i te ASTM D6413). Kāore te Ba-Zn e tauhohe ki ngā tāpiringa ārai mura, nō reira ka taea e koe te eke ki ngā tohu haumaru me te kore e whakararu i te pumau.
3,Ngā Whakapūmau Whenua Onge: Mō ngā Tāpare Kaweake Kounga Nui
Mena kei te arotahi koe ki ngā mākete papai - pērā i ngā tāpare ahuwhenua o Ūropi, i ngā whare whakangāhau rānei o Amerika Te Raki - ko ngā mea whakaū whenua onge (ngā ranunga o te lanthanum, te cerium, me te zinc) te huarahi pai. He nui ake te utu i te Ca-Zn, i te Ba-Zn rānei, engari he pai ngā painga e tika ana mō te utu:
• He ātete ki te huarere. Ka ātete ngā mea whakaū whenua onge ki te hihi UV me te makariri rawa (tae atu ki te -30°C), ā, he pai mō ngā tāpare e whakamahia ana i ngā āhuarangi maunga, i te raki rānei. Ka whakamahia ēnei e tētahi waitohu taputapu o waho o Kanata mō ngā tāpare puni, ā, kāore he hokinga mai nā te pakaru e pā ana ki te makariri.
• Te tutuki i ngā paerewa taiao tino pakari. Kāore he konganuku taumaha i roto, ā, e tutuki ana i ngā ture tino pakari a te EU mō ngā hua PVC "matomato". He mea nui tēnei hei hoko mā ngā kaihoko e hiahia ana ki te utu nui ake mō ngā taonga pumau.
• Ngā penapena utu mō te wā roa. Ahakoa he nui ake te utu o mua, ka whakaitihia e ngā whakapūmau whenua onge te hiahia mō te mahi anō me te whakahokinga mai. I roto i te tau kotahi, he maha ngā kaihanga e kite ana ka penapena moni rātou ki te whakataurite ki ngā whakapūmau iti ake te utu e puta ai ngā raruraru kounga.

Me pēhea te whakapakari i te mahi a tō pūmau (Tohutohu Whakaputa Whaihua)
Ko te whiriwhiri i te pūmau tika te haurua o te pakanga—ko te whakamahi tika te haurua kē atu. Anei ngā mahi tinihanga e toru mai i ngā kaihanga tāpa tauhou:
1. Kaua e nui rawa te horopeta
He mea whakamatautauria te tāpiri i tētahi atu mea whakaū "hei haumaru noa iho," engari he moumou moni tēnei, ā, ka whakapakeke pea i ngā tāpare. Mahi tahi me tō kaiwhakarato ki te whakamātautau i te horopeta iti rawa e whai hua ana: tīmata ki te 1% mō te Ca-Zn, 1.5% mō te Ba-Zn, ka whakarerekē i runga i te pāmahana whakaputa me te matotoru o te tāpare. I whakahekehia e tētahi wheketere tāpare Mehiko ngā utu whakaū mā te 15% mā te whakaiti noa i te horopeta mai i te 2.5% ki te 1.8%—me te kore e heke te kounga.
;
2,Tāruatia ki ngā Tāpiri Tuarua
He pai ake te mahi a ngā whakaū me te tārua. Mō ngā tāpare o waho, tāpirihia he 2–3% hinu pīni soya epoxidized (ESBO) hei whakanui ake i te ngāwari me te ātete ki te makariri. Mō ngā whakamahinga UV-nui, whakaranua he iti noa te antioxidant (pēnei i te BHT) hei aukati i te kino o ngā rauropi kore utu. He iti te utu o ēnei tāpiringa, ā, ka whakanuia te whai huatanga o tō whakaū.
3,Whakamātauria tō āhuarangi
Me nui ake te tiaki UV mō tētahi tāpa e hokona ana i Florida i tērā e hokona ana i te kawanatanga o Washington. Whakahaerehia ngā whakamātautau iti: whakaaturia ngā tāpa tauira ki te mārama UV whaihanga (mā te whakamahi i te ine huarere) mō te 1,000 hāora, whakatio rānei i te pō ka tirohia mēnā he pakaru. Mā tēnei ka whakarite kia ōrite tō ranunga whakaū ki tō mākete ūnga.'ngā tikanga.
Ka tautuhia e ngā Whakaū tō Tāpa'Uara
I te mutunga o te rā, kāore ō kaihoko e aro ki te momo whakaū e whakamahia ana e koe—e aro ana rātou kia mau tonu tā rātou tāpare i te ua, i te rā, me te hukarere. Ehara i te mea he utu nui te whiriwhiri i te whakaū PVC tika; he huarahi tēnei ki te hanga ingoa mō ngā hua pono. Ahakoa kei te hanga tāpare ahuwhenua utu iti koe (kia mau ki te Ca-Zn) he uhi ahumahi kounga teitei rānei (whiriwhiria te Ba-Zn, te whenua onge rānei), ko te mea nui ko te whakataurite i te whakaū ki te kaupapa o tō tāpare.
Ki te kore tonu koe e tino mōhio ko tēhea ranunga e pai ana mō tō raina, pātai atu ki tō kaiwhakarato whakaū mō ngā puranga tauira. Whakamātauria i roto i tō tukanga whakaputa, whakaaturia ki ngā āhuatanga o te ao tūturu, ā, waiho mā ngā hua e ārahi koe.
