Āhuatanga 1: Ko te PVC pakari tētahi o ngā rauemi kirihou e whakamahia whānuitia ana. He rauemi kore-kirikiri te rauemi PVC.

Āhuatanga 2: He maha ngā wā ka tāpirihia ngā whakaū, ngā hinu whakahinuhinu, ngā kaihoko tukatuka āwhina, ngā tae, ngā kaihoko ārai-pānga me ētahi atu tāpiringa ki ngā rauemi PVC i te whakamahinga tūturu.

Āhuatanga 3: He kore mura te rauemi PVC, he kaha teitei, he ātete ki te huarere, ā, he tino pumau te āhuahanga.

Āhuatanga 4: He kaha te ātete o te PVC ki ngā waikura, ngā matū whakaiti me ngā waikawa kaha. Heoi, ka taea te waikura e ngā waikawa waikura kukū pērā i te waikawa whanariki kukū me te waikawa hauota kukū, ā, kāore e pai mō te whakapā atu ki ngā warowaihā kakara me ngā warowaihā kua whakapūkaratia.

Āhuatanga 5: He mea tino nui te pāmahana rewa o te PVC i te wā e tukatukahia ana. Mēnā kāore tēnei āhuatanga i te tika, ka raru pea te pirau o ngā rauemi.

Āhuatanga 6: He tino ngoikore ngā āhuatanga rere o te PVC, ā, he tino whaiti te whānuitanga o tana tukanga. Ina koa ko te rauemi PVC taumaha-ngota he uaua ake te tukatuka (me tāpiri he hinu whakahinuhinu ki tēnei momo rauemi hei whakapai ake i ngā āhuatanga rere), nō reira ko te rauemi PVC he iti te taumaha-ngota te mea e whakamahia ana.

Āhuatanga 7: He tino iti te tere whakaheke o te PVC, ko te tikanga he 0.2~0.6%.

Ko te Polyvinyl chloride, e whakarāpopototia ana ko te PVC (Polyvinyl chloride) i te reo Ingarihi, he monomer vinyl chloride (VCM) i roto i ngā peroxides, ngā matū azo me ētahi atu kaiwhakaoho; i raro rānei i te mahi a te mārama me te wera e ai ki te tikanga tauhohenga polymerization radical kore utu. Ko ngā polymer i hangaia mā te polymerization ko te homopolymer vinyl chloride me te copolymer vinyl chloride.

He paura mā te PVC, he āhua kore-āhua. He iti te kaha o te peka, ko te kiato whanaunga he 1.4 pea, ko te pāmahana whakawhiti karāhe he 77~90℃, ā, ka tīmata te pirau i te 170℃ pea. He ngoikore te pumau ki te mārama me te wera, neke atu i te 100℃, i muri rānei i te wā roa. Ka pirau te hihi o te rā ka puta he hauwai pūhaumāota, ka whakakorikori anō i te pirau, ka puta te tae rerekē, ā, ka tere hoki te heke o ngā āhuatanga ā-tinana me ā-pūkaha. I roto i ngā mahi whaihua, me tāpiri he mea whakaū hei whakapai ake i te pumau ki te wera me te mārama.

Ko te taumaha ngota o te PVC i hangaia i te ahumahi kei te awhe o te 50,000 ki te 110,000, me te polydispersity nui, ā, ka piki ake te taumaha ngota i te hekenga o te pāmahana polymerization; kāore he ira rewa pumau, ka tīmata te ngawari i te 80-85 ℃, ā, ka huri hei viscoelastic i te 130 ℃, ka tīmata te huri ki te āhua wai matotoru i te 160 ~ 180 ℃; he pai ngā āhuatanga miihini, ko te kaha kume he tata ki te 60MPa, ko te kaha pānga he 5 ~ 10kJ/m2, ā, he pai ngā āhuatanga dielectric.

Ko te PVC te kaihanga kirihou whānui nui rawa atu o te ao i mua, ā, he whānui te whakamahinga. He whānui te whakamahinga i roto i ngā rauemi hanga, ngā hua ahumahi, ngā mea e hiahiatia ana i ia rā, te hiako papa, ngā taera papa, te hiako horihori, ngā paipa, ngā waea me ngā taura, ngā kiriata takai, ngā pounamu, ngā rauemi pahuka, ngā rauemi hiri, ngā muka, me ētahi atu.

He pai te whakamahinga a tā mātou wheketerepokepokea aingā rauemi, pērā i te 718, 718H, me ētahi atu, he pai ngā rauemi pokepokea ai, he roa ake te ora, ā, ka taea e ngā hua e whakamahia ana i roto i ngā rauemi kirihou rerekē te whakaputa hua kirihou kounga teitei.
