Polyvinyl chloride

ʻO ka polyvinyl chloride, PVC, he polymer i hana ʻia e ka vinyl chloride monomer (VCM) i loko o ka peroxide, nā hui azo a i ʻole ka hana polymerization o ka polymerization radical ma lalo o ka mālamalama a me ka wela.Ua kapa ʻia ʻo Ethylene chloride homopolymer a me ka vinyl chloride copolymer system.ʻO PVC ka mea i hoʻohana nui ʻia ma ka honua.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, ka papahele papahele, ka ʻili artificial, ka mea paipu, ka uea a me ke kaula, ka pahu kiʻiʻoniʻoni, nā ʻōmole, nā mea hoʻohuhū, nā mea hoʻopaʻa, fiber a me nā mea ʻē aʻe.Wahi a ka ʻokoʻa o ka noi, hiki ke hoʻokaʻawale ʻia ka PVC i: ʻano maʻamau PVC resin, polymerization kiʻekiʻe PVC resin, cross-linked PVC resin.Hoʻokumu ʻia ka resin PVC ʻano maʻamau e ka polymerization o ka monomer vinyl chloride ma lalo o ka hana a ka mea hoʻomaka;ʻO ka polymerization kiʻekiʻe PVC resin e pili ana i ka polymer o ka polymerization system;a ua haku ʻia ka resin PVC i hoʻopaʻa ʻia me kahi mea hoʻopili i loaʻa ka diene a me ka polyene i loko o ka vinyl chloride monomer polymerization system.E like me ke ʻano o ka loaʻa ʻana o ka monomer ethylene chloride, hiki ke hoʻokaʻawale ʻia i ke ʻano calcium carbide, ke ʻano ethylene a me ka lawe ʻia ʻana (EDC, VCM) monomer (EDC, VCM) monomer method (ethylene method and imported monomer method is habitually called ethylene method).Wahi a ke ʻano polymerization, hiki ke hoʻokaʻawale ʻia ka PVC i ʻehā mau ʻāpana: ke ʻano hoʻokuʻu PVC, ke ʻano emulsion PVC, ke ʻano nui PVC, ke ʻano hoʻonā PVC.ʻO Suspension PVC ka hua nui loa, e helu ana ma kahi o 80% o ka nui o ka PVC.Hoʻokaʻawale ʻia ke ʻano hoʻomaha o PVC i ʻeono mau hiʻohiʻona: XS-1, XS-2..., XS-6;XJ-1, XJ-2..., XJ-6.ʻO ke ʻano o kēlā me kēia leka i ke kumu hoʻohālike: X-suspension method;S-ʻano wehe;ʻAno J-paʻa.E like me ka maʻiʻo o ka plasticizer, PVC plastic ene plastic ua mahele pinepine i: ʻaʻohe plasticizer PVC, plasticizer maʻiʻo he 0;ʻO ka PVC paʻakikī, ka mea plasticizer ma lalo o 10%;semi-paʻakikī PVC, plasticizer maʻiʻo o 10-30%;PVC palupalu, mea plasticizer o 30-70%;polyvinyl
