Polyvinyl chloride (PVC)plastike ni ibintu byinshi byakozwe muguhuza PVC resin ninyongeramusaruro zitandukanye. Irerekana ibikoresho byiza byubukanishi, kurwanya imiti yangirika, ibiranga kwizimya, guhangana nikirere cyiza, uburyo bwiza bwo gukwirakwiza amashanyarazi, koroshya gutunganya, hamwe nigiciro gito, bigatuma iba ibikoresho byiza byokoresha insinga ninsinga hamwe no gukata.
PVC resin ni umurongo wa termoplastique polymer wakozwe na polymerisation ya vinyl chloride monomers. Imiterere ya molekulire iranga:
(1) Nka polymer ya termoplastique, yerekana plastike nziza kandi ihinduka.
. Iyi nkunga ya polar nayo igira uruhare mumbaraga zikomeye za intermolecular nimbaraga zikomeye za mashini.
. Nyamara, ayo atome ya chlorine ahungabanya imiterere ya kristaline, biganisha ku kurwanya ubushyuhe buke ugereranije no kurwanya ubukonje bukabije, bushobora kunozwa binyuze mu nyongeramusaruro ikwiye.
2.Ubwoko bwa PVC Resin
Uburyo bwa polymerisation kuri PVC burimo: guhagarika polymerisation, polymerisiyasi ya emulsiya, polymerisiyasi nyinshi, hamwe na polymerisiyasi.
Uburyo bwo guhagarika polymerisation buriganje cyane mubikorwa bya PVC resin, kandi ubu ni ubwoko bukoreshwa mugukoresha insinga na kabili.
Ihagarikwa rya polymerisike ya PVC ishyizwe muburyo bubiri:
Ubwoko bwa resin (Ubwoko bwa XS): Kurangwa nuburyo bubi, kwinjiza plastike nyinshi, plastike yoroshye, kugenzura neza gutunganya, hamwe na geli nkeya, bigatuma ihitamo neza mugukoresha insinga na kabili.
Ubwoko bwa compact-resin (XJ-ubwoko): Ahanini bikoreshwa mubindi bicuruzwa bya plastiki.
3.Key Ibiranga PVC
. Ijwi rirwanya hejuru ya 10¹⁵ Ω · cm; kuri 25 ° C na 50Hz inshuro, dielectric ihoraho (ε) iri hagati ya 3.4 na 3.6, iratandukanye cyane nubushyuhe nimpinduka zinshyi; ibintu byo gutandukana (tanδ) biva kuri 0.006 kugeza 0.2. Imbaraga zo gusenyuka zikomeza kuba hejuru mubushyuhe bwicyumba ninshuro zingufu, bitatewe na polarite. Nyamara, kubera igihombo cyinshi cya dielectric, PVC ntabwo ikwiranye na voltage nyinshi hamwe na progaramu nyinshi zikoreshwa, mubisanzwe bikoreshwa nkibikoresho byo kubika insinga ntoya na hagati ya voltage iri munsi ya 15kV.
. Oxidation itera kwangirika cyangwa guhuza, bigatera ibara, guhindagurika, kugabanuka gukabije kwimashini, no kwangirika kwimikorere yumuriro. Kubwibyo, stabilisateur ikwiye igomba kongerwaho kugirango irusheho kurwanya gusaza.
. Hamwe nubushyuhe bwikirahure (Tg) hafi 80 ° C hamwe nubushyuhe bwo gutemba hafi 160 ° C, PVC muburyo bwikirahure mubushyuhe bwicyumba ntishobora kuba yujuje ibyangombwa bisabwa. Guhindura birakenewe kugirango ugere kuri elastique hejuru yubushyuhe bwicyumba mugihe ukomeje ubushyuhe buhagije nubukonje bukonje. Kwiyongera kwa plasitike birashobora guhindura neza ubushyuhe bwikirahure.
IbyerekeyeISI imwe (OW Cable)
Nkumuntu wambere utanga ibikoresho byinsinga ninsinga, UMWE WISI (OW Cable) utanga ibikoresho byiza bya PVC murwego rwo kubika no gukata, bikoreshwa cyane mumashanyarazi, insinga zubaka, insinga zitumanaho, hamwe nogukoresha amamodoka. Ibikoresho byacu bya PVC biragaragaza amashanyarazi meza cyane, kutagira umuriro, hamwe no guhangana n’ikirere, twubahiriza amahame mpuzamahanga nka UL, RoHS, na ISO 9001. Twiyemeje gutanga ibisubizo byizewe kandi bihendutse bya PVC bijyanye nibyo abakiriya bacu bakeneye.
