Chlorine polyvinyl chloride (CPVC) ni ibikoresho bya polymer byabonetse nyuma ya chlorine ya PVC.Imiterere yumubiri na chimique ihinduka cyane: hamwe no kwiyongera kwa chlorine, kutubahiriza urunigi rwa molekile byiyongera kandi kristu ikagabanuka;polarite yumunyururu wa molekile iriyongera, imbaraga za intermolecular ziriyongera, ubushyuhe bwo guhindura ubushyuhe bwiyongera cyane, kandi nubukanishi bwiyongera.

CPVC iruta kure cyane PVC mukurwanya ikirere, kurwanya gusaza no kwirinda flame.Kurugero, nyuma ya chlorine, igipimo ntarengwa cya ogisijeni ya PVC kizazamuka kiva kuri 45 ~ 49 kigere kuri> 70 (kirimo chlorine ya CPVC 67%), kandi umwotsi hamwe na karubone isigaye mumuriro bizagabanuka cyane.Inzira ya Chlorination yagize ingaruka kumiterere yibicuruzwa.Chlorine irimo PVC irashobora kugera kuri 73% nyuma ya chlorine.

Mubisanzwe muburyo bwo guhagarika icyiciro cyamazi, nyuma yo kuvanga resin ya PVC, hamwe na chlorine, kuyungurura, gukaraba, umusaruro wa CPVC wo kutabogama, inzira yo kumisha irarangiye, ubwiza bwibiti bya PVC byifu yibiti ni ingenzi cyane cyane bigira ingaruka kumashanyarazi, gutekesha ubushyuhe) , guhitamo PVC resin ibikoresho bibisi birekuye, uruhu ruto rushoboka, imiterere yurwego rwiza rwiza.Muri rusange ibirimo chlorine ni 63% ~ 67%.Kurwanya ikirere cyayo, kurwanya ruswa, kurwanya gusaza hamwe no gutwika flame bidatinze ni byiza cyane kuruta PVC isanzwe.Ibirungo bya chlorine byiyongera, bityo ubushyuhe bwa vica bworoshya ubushyuhe bwiyongereye cyane, 35 ℃ hejuru ya PVC, ubushyuhe bwo hejuru bw’ubushyuhe bugera kuri 130 ℃, bukwiranye n’imiyoboro irwanya ubushyuhe hamwe n’ibikoresho hamwe n’isahani (nk'imiyoboro y'amazi ashyushye, ingingo, irwanya ubushyuhe ibikoresho bya shimi n'ibigega byo kubikamo).

UPVC irakomeye PVC.Ibikoresho byahinduwe byateguwe hongerwaho umubare runaka winyongera zahinduwe hashingiwe kubifu ya PVC."U" ni Unplasticized (Unplasticized), bityo itandukaniro nyamukuru riri hagati ya UPVC na PVC na PVC yoroshye nuko nta plastiseri yongeweho, ifu ya calcium nyinshi, imbaraga za mashini zikoreshwa mubikoresho, bikwiranye no gukora valve n'imiyoboro.

CPVC ni chlorine polyvinyl chloride.Hashingiwe ku bisigazwa bya PVC, CPVC yongerera chlorine mu bikoresho bya PVC mu buryo runaka, muri rusange ikaba iri hagati ya 63 na 69%, kugira ngo irusheho guhangana n’ubushyuhe, aside, alkali, umunyu na okiside yangirika y’ibikoresho, kandi bitezimbere ubushyuhe. ubushyuhe bwo guhindura ibintu hamwe nubukanishi bwibikoresho.

CPVC yongerera chlorine ibirimo PVC ikoresheje uburyo bwa shimi, bityo igiciro cyibikoresho bya resin ya CPVC ni kinini.Mucyiciro cyakurikiyeho, ibikoresho bimwe byahinduwe bigomba gukoreshwa mugutera inshinge cyangwa kubisohora, bikavamo igiciro kinini cyibikoresho byahinduwe na CPVC.Igiciro cyo kugurisha ibice byahinduwe na CPVC mubushinwa muri rusange biri hejuru ya 20.000 / toni.

Kubera igiciro kinini cya CPVC, ntibishoboka ko ibi bikoresho byakoreshwa cyane nka UPVC.Kugeza ubu, CPVC ikoreshwa cyane cyane mu miyoboro irwanya umuriro, imiyoboro irwanya ruswa ndetse n’imiyoboro y’amazi ashyushye.
