ibicuruzwa

Urwego rwa PVC,
PVC ya firime, PVC resin ya Flexible Vinyl Film, PVC resin ya Rigid Vinyl Film,

Filime ya PVC idafite plastike yitwa firime vinil firime, mugihe PVC ya plastike yitwa vinyl firime yoroheje.
1. Filime yoroheje ya Vinyl

Filime yoroheje ya vinyl ifite inzitizi nziza kumavuta namavuta ariko ni ogisijeni yinjira.Ifite kandi kwizirika neza, gusobanuka neza no kwihanganira gucumita.Iyi miterere ituma PVC ihindagurika ikwiriye gupakira ibiryo kugirango inyama nibindi byangirika bibe bishya (mugihe FDA yemeye).Nyamara, PVC ifite plastike ifite aho ishonga, ntishobora kwihanganira imiti, kandi ifite imbaraga zo hasi cyane kuruta vinyl.

2.Rigid Vinyl Film

Rigid vinyl, izwi kandi nka polyvinyl chloride idafite amashanyarazi (uPVC), ni firime ikomeye kandi yoroshye.Nimwe muma firime aramba kandi ahendutse kandi arwanya imiti myinshi.Mubisanzwe, uPVC irashobora gukoreshwa mubushuhe gushika kuri 60 ° C.Ifite imbaraga zingana na modulus kuruta PVC yoroheje, ariko ifite ingaruka nke zikomeye, kandi ishobora guhura nibibazo bitewe nibidukikije.

PVC ifite aho igarukira n'ibibi;plasitiki irashobora gukomera mubihe bikonje kandi ikoroshya mubihe bishyushye, biganisha kumihindagurikire yimiterere kandi irashobora guhungabanya imbaraga za kashe.PVC irekura kandi hydrogène chloride nkeya mu kirere kandi ikabyara karubone ku bikoresho bifunga iyo bishyushye.Kubera iyo mpamvu, umwuka mwiza urakenewe mugihe ufunze PVC kugabanuka-gupfunyika.

GUSABA
Filime ya PVC ikoreshwa nko kugabanya no kurambura ibicuruzwa ku nganda n’abaguzi ndetse no gupfunyika pallet, nyamara, ku gipimo gito cyane ugereranije na firime polyolefin.Ibindi bikoreshwa birimo imifuka, imirongo, gutobora amacupa, gufata kaseti ifata inyuma, ibirango, imifuka yamaraso hamwe n imifuka ya IV.Bikunze kuba PVDC itwikiriwe mugihe hagomba gukenerwa uburyo bwiza bwo gukumira inzitizi.

FDA yemewe na PVC ni amahitamo meza yo gupakira inyama zitukura nshya kuko irigice kimwe, bivuze ko ari ogisijeni ihagije kugira ngo ibicuruzwa byinyama bigume bishya kandi bigumane ibara ryumutuku.Iyo gukorera mu mucyo ari ngombwa, PVC ikoreshwa kenshi.

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.
