ʻO ka hiʻohiʻona 1: ʻO PVC paʻa ʻo ia kekahi o nā mea plastik i hoʻohana nui ʻia.ʻO ka mea PVC he meaʻeleʻeleʻole.
Hōʻike 2: Hoʻohui pinepine ʻia nā stabilizers, lubricants, auxiliary processing agents, pigments, anti-impact agents a me nā mea hoʻohui ʻē aʻe i nā mea PVC i ka hoʻohana maoli ʻana.
Hōʻike 3: ʻAʻole hiki ke puhi ʻia nā mea PVC, ikaika kiʻekiʻe, kū i ka wā a me ke kūpaʻa geometric maikaʻi loa.
Hōʻike 4: He kūpaʻa ikaika ka PVC i nā oxidants, nā mea hoʻemi a me nā waikawa ikaika.Eia naʻe, hiki ke hoʻopōʻino ʻia e nā ʻakika oxidizing concentrated e like me ka waikawa sulfuric concentrated a me ka waikawa nitric concentrated a ʻaʻole kūpono no ka hoʻopili ʻana me nā hydrocarbons aromatic a me nā hydrocarbons chlorinated.
Hōʻike 5: ʻO ka wela hoʻoheheʻe o PVC i ka wā o ka hana ʻana he mea koʻikoʻi kaʻina hana.Inā kūpono ʻole kēia ʻāpana, e hoʻopilikia ʻia ka decomposition waiwai.
Hiʻona 6: He ʻilihune loa nā hiʻohiʻona kahe o PVC, a he haiki loa kona ʻano kaʻina hana.ʻOi aku ka paʻakikī o ka hana ʻana i nā mea PVC molecular kiʻekiʻe (ʻo kēia ʻano mea pono e hoʻohui i ka lubricant no ka hoʻomaikaʻi ʻana i nā ʻano kahe), no laila hoʻohana mau ʻia ka mea PVC me ke kaumaha molekala liʻiliʻi.
Hōʻike 7: He haʻahaʻa haʻahaʻa ka emi ʻana o PVC, maʻamau 0.2 ~ 0.6%.
ʻO ka Polyvinyl chloride, i hoʻopau ʻia e like me PVC (Polyvinyl chloride) ma ka ʻōlelo Pelekania, he vinyl chloride monomer (VCM) i nā peroxides, nā hui azo a me nā mea hoʻomaka;a i ʻole ma lalo o ka hana o ka māmā a me ka wela e like me ke ʻano hana hoʻoheheʻe ʻana o ka radical manuahi.ʻO Vinyl chloride homopolymer a me vinyl chloride copolymer i hui pū ʻia me ka vinyl chloride resin.
ʻO PVC kahi pauka keʻokeʻo me kahi ʻano amorphous.He liʻiliʻi ke kiʻekiʻe o ka lālā, ʻo ka pili pili ma kahi o 1.4, ʻo ke aniani hoʻololi ke aniani ʻo 77 ~ 90 ℃, a hoʻomaka ia e decompose ma kahi o 170 ℃.He ʻilihune ka paʻa o ka māmā a me ka wela, ma luna o 100 ℃ a i ʻole ma hope o ka manawa lōʻihi.E pohō ana ka lā i mea e hana ai i ka hydrogen chloride, ka mea e hoʻomaʻemaʻe hou i ka decomposition, e hoʻoneʻe ai, a e emi koke nā waiwai kino a me nā mīkini.Ma nā noi kūpono, pono e hoʻohui ʻia nā stabilizers e hoʻomaikaʻi i ka paʻa i ka wela a me ka māmā.
ʻO ke kaumaha molekala o PVC i hana ʻia ma ka ʻoihana ma ke ʻano he 50,000 a 110,000, me ka polydispersity nui, a piʻi ka paona mole me ka emi ʻana o ka mahana polymerization;ʻaʻohe wahi hoʻoheheʻe paʻa, hoʻomaka e palupalu ma 80-85 ℃, a lilo i viscoelastic ma 130 ℃, 160 ~ 180 ℃ hoʻomaka e hoʻololi i ke kūlana wai viscous;Loaʻa iā ia nā waiwai mechanical maikaʻi, ʻo ka ikaika tensile ma kahi o 60MPa, ʻo ka ikaika hopena ʻo 5 ~ 10kJ/m2, a he mau waiwai dielectric maikaʻi loa.
ʻO PVC ka mea hana nui loa o ka honua i nā plastics kumu nui, a hoʻohana nui ʻia.Hoʻohana nui ʻia ia i nā mea kūkulu hale, nā huahana ʻoihana, nā mea e pono ai i kēlā me kēia lā, ka ʻili papahele, nā tile papahele, nā ʻili artificial, nā paipu, nā uea a me nā kaula, nā kiʻi ʻoniʻoni, nā ʻōmole, nā mea huʻihuʻi, nā mea sealing, fibers, etc.
Hoʻohana maikaʻi kā mākou hale hanapoʻonā mea waiwai, e like me 718, 718H, a me nā mea ʻē aʻe, nā mea hoʻoheheʻe maikaʻi, ke ola lōʻihi, a me nā huahana i hoʻohana ʻia i nā mea plastik like ʻole hiki ke hana i nā huahana plastik kiʻekiʻe.
