PVC K agaciro ka 57
PVC K agaciro ka 57,
PVC resin yakoreshwaga mu gukora ikibaho,
PVC resin ifite K ifite agaciro ka 55-68 irashobora gukoreshwa mugukora ifuro rikomeye, ni ukuvuga ibicuruzwa bikomeye bya PVC bito-ifuro, bitandukanye nagaciro ka K yatanzwe mumakuru yashize hamwe nibitabo.PVC isigarana ifite K agaciro ka 69-77 yerekanwe ko ikwiriye gukora ifuro ryoroshye.Hariho uburyo bwinshi bwo kubyara resinike ya PVC, uburyo bwo guhagarika, uburyo bwa emulsion hamwe na polymerisiyasi nyinshi ya PVC resin iraboneka ibikoresho fatizo kubicuruzwa bibyibushye, mubisanzwe guhagarikwa hamwe na polymerisiyasi nyinshi za PVC birakwiye.PVC copolymers hamwe na polymers yashizwemo (granular polymers) nabyo bifite imikorere myiza kandi ntibikoreshwa gake kubera ibiciro.
Polyvinyl Chloride, yitwa PVC, ni bumwe mu bwoko bwa pulasitiki bwateye imbere mu nganda, umusaruro uriho ni uwa kabiri nyuma ya polyethylene.Polyvinyl chloride yakoreshejwe cyane mu nganda, mu buhinzi no mu buzima bwa buri munsi.Polyvinyl chloride ni polymer compound polymerized na vinyl chloride.Ni thermoplastique.Ifu yera cyangwa yoroheje yumuhondo.Birashonga muri ketone, esters, tetrahydrofurans na hydrocarbone ya chlorine.Kurwanya imiti nziza cyane.Ubushyuhe buke bwumuriro no kurwanya urumuri, birenga 100 ℃ cyangwa igihe kinini cyumucyo wizuba byatangiye kubora hydrogène chloride, gukora plastike bigomba kongeramo stabilisateur.Gukwirakwiza amashanyarazi nibyiza, ntabwo bizashya.
Icyiciro S-700ikoreshwa cyane cyane mugukora impapuro zibonerana, kandi irashobora kuzunguruka mumpapuro zikomeye kandi zidakomeye kubipaki, ibikoresho byo hasi, firime ikomeye yo gutondekanya (kubipfunyika bombo cyangwa impapuro zipakira itabi), nibindi. igice cya firime ikomeye, urupapuro, cyangwa akabari kameze kuburyo budasanzwe.Cyangwa irashobora guterwa kugirango ikore ingingo, valve, ibice byamashanyarazi, ibikoresho byimodoka nibikoresho.
