PVC S-700
PVC S-700,
impapuro zibonerana PVC resin,
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 cya S-700 gikoreshwa cyane cyane mukubyara flake ibonerana, kandi irashobora gukanda kumutwe cyangwa igice gikomeye cyangwa igice cyo gupakira, ibikoresho byo hasi, firime ikomeye yo gutondekanya (kubipfunyika bombo cyangwa impapuro zipakira itabi), nibindi birashobora na none gusohokera kubice bikomeye cyangwa igice-gikomeye, urupapuro, cyangwa umurongo utunganijwe muburyo bwa paki.Cyangwa irashobora guterwa kugirango ikore ingingo, valve, ibice byamashanyarazi, ibikoresho byimodoka nibikoresho.
