PVC Resin ni iki?

Polyvinyl chloride (PVC) ni polymeri ikozwe muri vinyl chloride monomer (VCM) muri peroxide, azo compound n'ibindi bintu byatangije cyangwa hakurikijwe uburyo bwa polymerize yigenga ikorwa n'urumuri n'ubushyuhe. Vinyl chloride homopolymer na vinyl chloride copolymer byose hamwe byitwa vinyl chloride resin.

PVC yari pulasitiki nini cyane ku isi ikoreshwa mu bikorwa rusange, ikaba yarakoreshwaga cyane. Ikoreshwa cyane mu bikoresho by'ubwubatsi, mu nganda, mu bikoresho bya buri munsi, mu ruhu rwo hasi, mu matafari yo hasi, mu ruhu rw'ubukorano, mu miyoboro, mu nsinga n'insinga, mu mafirime yo gupfunyika, mu macupa, mu bikoresho byo gufuro, mu bikoresho byo gufunga, mu nsinga n'ibindi.

Dukurikije uburyo butandukanye bwo gukoresha, PVC ishobora kugabanywamo ibice bikurikira: resini ya PVC ikoreshwa muri rusange, resini ya PVC ifite urwego rwo hejuru rwa polymerization na resini ya PVC ifite cross-linked. Resini ya PVC ifite plus-linked ikorwa na polymerization ya monomer ya vinyl chloride ikoresheje imbaraga za starter; Resini ya PVC ifite plus-linked bivuze resini ya polymerized binyuze mu kongeramo agent yo gukura mu muyoboro muri sisitemu ya vinyl chloride monomer ya polymerization; Resini ya PVC ifite crosslinked ni resini ya polymerized binyuze mu kongeramo agent irimo diene na polyene muri sisitemu ya vinyl chloride monomer ya polymerization.
Dukurikije uburyo bwo kubona monomer ya vinyl chloride, ishobora kugabanywamo uburyo bwa karuboni kalisiyumu, uburyo bwa ethylene n'uburyo bwa monomer butumijwe hanze (EDC, VCM) (ubusanzwe, uburyo bwa ethylene n'uburyo bwa monomer butumijwe hanze byitwa uburyo bwa ethylene).
