Hiʻona 1: ʻO ka PVC paʻa kekahi o nā mea palaki i hoʻohana nui ʻia. He mea crystalline ʻole ka mea PVC.

Hiʻona 2: Hoʻohui pinepine ʻia nā mea hoʻopaʻa, nā lubricants, nā mea hana kōkua, nā pigments, nā mea anti-impact a me nā mea hoʻohui ʻē aʻe i nā mea PVC i ka hoʻohana maoli ʻana.

Hiʻona 3: ʻAʻole hiki ke lapalapa ka mea PVC, ikaika kiʻekiʻe, kūpaʻa i ka wā a me ke kūpaʻa geometric maikaʻi loa.

Hiʻona 4: Loaʻa i ka PVC ke kūpaʻa ikaika i nā oxidants, nā mea hoʻemi a me nā waikawa ikaika. Eia nō naʻe, hiki ke palaho ʻia e nā waikawa oxidizing i hoʻohuihui ʻia e like me ka waikawa sulfuric i hoʻohuihui ʻia a me ka waikawa nitric i hoʻohuihui ʻia a ʻaʻole kūpono no ka hoʻopili ʻana me nā hydrocarbons ʻala a me nā hydrocarbons chlorinated.

Hiʻona 5: ʻO ka mahana hoʻoheheʻe o ka PVC i ka wā o ka hana ʻana he mea nui loa ia o ke kaʻina hana. Inā kūpono ʻole kēia palena, e hoʻopilikia ia i ka palaho ʻana o nā mea.

Hiʻona 6: ʻAʻole maikaʻi loa nā ʻano kahe o ka PVC, a he haiki loa kona laulā hana. ʻOi aku ka paʻakikī o ka hana ʻana i ka mea PVC kaumaha molekala kiʻekiʻe (pono pinepine kēia ʻano mea e hoʻohui i ka lubricant e hoʻomaikaʻi i nā ʻano kahe), no laila hoʻohana pinepine ʻia ka mea PVC me ke kaumaha molekala liʻiliʻi.

Hiʻona 7: Haʻahaʻa loa ka nui o ka emi ʻana o ka PVC, ma ke ʻano he 0.2 ~ 0.6%.

ʻO Polyvinyl chloride, i hoʻopōkole ʻia e like me PVC (Polyvinyl chloride) ma ka ʻōlelo Pelekania, he monomer vinyl chloride (VCM) i loko o nā peroxides, nā pūhui azo a me nā mea hoʻomaka ʻē aʻe; a i ʻole ma lalo o ka hana o ka mālamalama a me ka wela e like me ke ʻano hana polymerization radical manuahi. ʻO nā Polymers i hoʻokumu ʻia e ka polymerization. ʻO ka vinyl chloride homopolymer a me ka vinyl chloride copolymer i kapa ʻia ʻo vinyl chloride resin.

He pauka keʻokeʻo ka PVC me kahi ʻano amorphous. He liʻiliʻi ke kekelē o ka lālā ʻana, ʻo ka nui o ka mānoanoa ma kahi o 1.4, ʻo ka mahana hoʻololi aniani he 77 ~ 90 ℃, a hoʻomaka ia e pala ma kahi o 170 ℃. ʻAʻole maikaʻi ke kūpaʻa i ka mālamalama a me ka wela, ma luna o 100 ℃ a i ʻole ma hope o ka manawa lōʻihi. E pala ka lā e hana i ka hydrogen chloride, ka mea e hoʻoulu hou i ka palaho, e hoʻololi ai i ka ʻano, a e emi koke hoʻi nā waiwai kino a me nā mechanical. I nā hana kūpono, pono e hoʻohui ʻia nā mea hoʻopaʻa e hoʻomaikaʻi i ke kūpaʻa i ka wela a me ka mālamalama.

ʻO ke kaumaha molekala o ka PVC i hana ʻia e ka ʻoihana ma ka laulā ma waena o 50,000 a me 110,000, me ka polydispersity nui, a piʻi ke kaumaha molekala me ka emi ʻana o ka mahana polymerization; ʻaʻohe ona kiko heheʻe paʻa, hoʻomaka e palupalu ma 80-85 ℃, a lilo i viscoelastic ma 130 ℃, 160 ~ 180 ℃ hoʻomaka e hoʻololi i ke kūlana wai viscous; he mau waiwai mechanical maikaʻi kona, ʻo ka ikaika tensile ma kahi o 60MPa, ʻo ka ikaika hopena he 5 ~ 10kJ / m2, a he mau waiwai dielectric maikaʻi loa.

ʻO PVC ka mea hana nui loa o ka honua no nā palakiko maʻamau, a ua hoʻohana nui ʻia. Hoʻohana nui ʻia ia i nā mea kūkulu hale, nā huahana ʻoihana, nā mea pono o kēlā me kēia lā, ka ʻili papahele, nā tile papahele, ka ʻili hana, nā paipu, nā uea a me nā kaula, nā kiʻi ʻōwili, nā ʻōmole, nā mea hoʻohua, nā mea sila, nā olonā, a pēlā aku.

Hoʻohana kā mākou hale hana i ka maikaʻiʻōmolenā mea hana, e like me 718, 718H, a pēlā aku, nā mea hana hoʻoheheʻe maikaʻi, ke ola lōʻihi, a me nā huahana i hoʻohana ʻia i nā mea plastik like ʻole e hiki ke hana i nā huahana plastik kiʻekiʻe
