Ngā whakaū wera PVCHe mea nui tēnei hei whakarite i te mahi me te roa o ngā paipa PVC. He tāpiringa ēnei mea whakaū hei tiaki i ngā rauemi PVC mai i te pirau i puta mai i te wera, te mārama me te hāora. I roto i tēnei tuhinga, ka tūhuratia te whakamahinga o ngā mea whakaū wera PVC i roto i ngā paipa PVC me tōna hiranga ki te pupuri i te kounga o ngā paipa.
He rauemi maha ngā whakamahinga o te PVC, te polyvinyl chloride rānei, e whakamahia whānuitia ana i roto i te umanga hanga mō ngā momo mahi, tae atu ki ngā paipa, ngā hononga me ngā paipa wai. He whānuitia te whakamahinga o ngā paipa PVC i roto i te tuku wai, te rerenga wai, te whakamakuku me ngā pūnaha maimoatanga paru nā te mea he pakari, he ātete ki te waikura, he ngāwari hoki te tāuta. Heoi, ka pirau ngā rauemi PVC ina pāngia e te wera me te mārama, ka ngaro te kaha miihini me te tae ke.
Hei whakakore i tēnei wero, ka whakamahia ngā whakaū wera PVC hei tiaki i te rauemi PVC mai i te pirau wera i te wā e tukatukahia ana, e ora ana hoki ngā paipa PVC. Ko te kaupapa o ēnei whakaū he aukati i ngā tauhohenga pirau e puta ana ina pāngia te PVC e te wera me te mārama, ā, mā reira ka roa ake te ora o te paipa, ka mau tonu hoki ōna āhuatanga miihini.
He maha ngā momo whakaū wera PVC e whakamahia ana mō ngā paipa PVC, tae atu ki ngā whakaū mata, ngā whakaū tine, ngā whakaū konupūmā me ngā whakaū rauropi. He āhuatanga me ngā painga motuhake tō ia momo whakaū, ā, ko te whiriwhiri i te whakaū tino tika ka whakawhirinaki ki ngā whakaritenga motuhake o tō tono paipa PVC.
Ngā mea whakaū i ahu mai i te mata, pērā i te lead stearate me te lead trivalent sulfate, kua whakamahia whānuitia i ngā wā o mua nā te mea he tino pai te pumau o te wera me te iti o te utu. Heoi, nā ngā āwangawanga mō te taiao me te hauora, he maha ngā whenua kua mutu te whakamahi i ngā whakaū e ahu mai ana i te lead, ā, kua whakakapia ki ētahi atu whakaū.
Ngā mea whakaū i runga i te tine, pērā i te dibutyltin dilaurate me te tributyltin oxide, e mōhiotia ana mō tō rātou pumau wera me te mārama, e pai ai mō ngā tono e nui ana te pupuri tae. Ka tiakina hoki e ēnei whakaū ngā paipa PVC mai i te pirau i te wā e tukatukahia ana me te whakaaturanga o waho.
Ngā mea whakaū i runga i te konupūmā, pērā i te konupūmā stearate mengā kaiwhakaū konupūmā konutea, he momo whakakapi kore-paitini hei whakakapi i ngā whakaū e ahu mai ana i te mata, ā, e whakamahia whānuitia ana i roto i te hanga paipa PVC mō te wai inu me te takai kai. He pai te pumau o ēnei whakaū i te wera me te ātete ki te huarere, ā, he pai mō ngā mahi o waho.
Ko ngā whakaū rauropi, pērā i te hinu pīni soya kua whakapūkaratia me te methyltin mercaptide, i ahu mai i ngā pūtake taiao, ā, he rongonui nā ō rātou āhuatanga pai mō te taiao me te kore-paitini. Ka tiakina pai e ēnei whakaū ngā paipa PVC mai i te pirau wera, ā, he pai mō ngā tono me ngā ture taiao tino pakari.
I te wā e hangaia ana ngā paipa PVC, ka tāpirihia ngā mea whakau wera PVC ki te kapia PVC i te wā e whakaranua ana hei hanga i tētahi ranunga ōrite. Ka ārai pai ngā mea whakau i ngā tauhohenga pirau i puta mai i te wera me te mārama mā te hanga i ngā matatini me ngā mekameka polymer PVC. Mā tēnei ka mau tonu te kaha miihini, te pumau tae me te āhua o te paipa PVC puta noa i tōna oranga mahi.
I roto i te roanga o te wā e whakamahia ana ngā paipa PVC, ka tere ake te pirau o ngā rauemi PVC mēnā ka pāngia e ngā āhuatanga o waho pērā i te rā, te piki me te heke o te pāmahana, ngā matū, me ētahi atu. He mea nui ngā mea whakaū wera PVC hei tiaki i ngā paipa mai i ēnei āhuatanga pirau, kia mau ai te mahi me te pono mō te wā roa.
He mea nui te whakamahinga o ngā whakaū wera PVC hei pupuri i te kounga me te mahi a ngā paipa PVC. Mā ēnei whakaū ka tiakina te rauemi PVC mai i te pirau wera, ā, ka whakarite kia mau tonu te āhua miihini, te pumau tae me te āhua o te paipa. I te whanaketanga haere o te hangarau whakaū, he maha ngā kōwhiringa hei whakatutuki i ngā whakaritenga motuhake o ngā tono paipa PVC rerekē. I te mea kei te piki haere tonu te hiahia mō ngā paipa PVC kounga teitei me te pakari, kāore e taea te whakanui rawa i te hiranga o ngā whakaū wera PVC i roto i te umanga paipa PVC.
