Gịnị bụ PVC resin?

Polyvinyl chloride (PVC) bụ polima e ji vinyl chloride monomer (VCM) mee ka ọ dị na peroxide, azo compound na ihe ndị ọzọ na-emepụta ya ma ọ bụ dịka usoro free radical polymerization si dị n'okpuru ọrụ nke ìhè na okpomọkụ. A na-akpọ vinyl chloride homopolymer na vinyl chloride copolymer dị ka vinyl chloride resin.

PVC bụbu plastik kachasị ukwuu n'ụwa, nke a na-ejikarị eme ihe n'ọtụtụ ebe. A na-ejikarị ya eme ihe n'ihe gbasara ụlọ, ngwaahịa ụlọ ọrụ mmepụta ihe, ihe ndị dị mkpa kwa ụbọchị, akpụkpọ anụ ala, taịlị ala, akpụkpọ anụ e ji aka rụọ, paịpụ, waya na eriri, ihe mkpuchi nkwakọ ngwaahịa, karama, ihe na-afụ ụfụfụ, ihe mkpuchi, eriri na ihe ndị ọzọ.

Dịka ngwa dị iche iche si dị, enwere ike kewaa PVC n'ime: resin PVC nke a na-eji eme ihe n'ozuzu, resin PVC nke a na-eji eme ihe n'ozuzu na resin PVC nke a na-eji eme ihe n'ozuzu. A na-emepụta resin PVC nke a na-eji eme ihe n'ozuzu site na ime ka monomer vinyl chloride dị n'okpuru ọrụ nke onye na-amalite; Resin PVC nke a na-eji eme ihe n'ozuzu na-ezo aka na resin nke a na-eji eme ihe n'ịgbakwụnye ihe na-eto eto na sistemụ polymerization nke vinyl chloride; Resin PVC nke a na-eji eme ihe n'ozuzu bụ resin nke a na-eji eme ihe n'etiti ihe na-ejikọta ọnụ nke nwere diene na polyene n'ime sistemụ polymerization nke vinyl chloride.
Dịka usoro esi enweta monomer vinyl chloride si dị, enwere ike kewaa ya n'ime usoro calcium carbide, usoro ethylene na usoro monomer ebubatara (EDC, VCM) (n'ọdịnala, a na-akpọ usoro ethylene na usoro monomer ebubatara ọnụ dị ka usoro ethylene).
