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 maha, 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, me te ngāwari o te tāutanga. 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 e ahu mai ana i te mata, ngā whakaū e ahu mai ana i te tine, ngā whakaū e ahu mai ana i te konupūmā me ngā whakaū e ahu mai ana i te rauropi. He āhuatanga me ngā painga motuhake tō ia momo whakaū, ā, ko te whiriwhiri i te whakaū tino tika e whakawhirinaki ana 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.
