Kumenyekanisha ibicuruzwa nibiranga

Styrene, ni ifumbire mvaruganda, formulaire ya chimique ni C8H8, electron ya vinyl na benzene impeta ya conjugate, idashobora gushonga mumazi, gushonga muri Ethanol, ether hamwe nandi mashanyarazi kama, ni monomer yingenzi ya resinike ya sintetike, ion yoguhindura resin na reberi yubukorikori.

Koresha

Ikoreshwa ryingenzi ni nka reberi yubukorikori hamwe na monomer ya plastike, ikoreshwa mu gukora reberi ya styrene butadiene, polystirene, ifuro rya polystirene;Irakoreshwa kandi muri copolymerize hamwe nabandi ba monomers kugirango bakore plastike yubuhanga ikoreshwa bitandukanye.Nka hamwe na acrylonitrile, butadiene copolymer ABS resin, ikoreshwa cyane mubikoresho bitandukanye byo murugo n'inganda;SAN ikoporora hamwe na acrylonitrile ni resin irwanya ingaruka kandi ibara ryiza.SBS ikoporora hamwe na butadiene ni ubwoko bwa reberi ya termoplastique, ikoreshwa cyane nka polyvinyl chloride, modifike ya polypropilene.
Styrene ikoreshwa cyane cyane mu gukora resin ya styrene hamwe na styrene BUTADIene reberi, nayo ni kimwe mu bikoresho fatizo byo gukora ion yo guhana imiti n’ubuvuzi, byongeye kandi, styrene ishobora no gukoreshwa mu buhanga mu bya farumasi, irangi, imiti yica udukoko ndetse n’amabuye y'agaciro. n'izindi nganda.3. Ikoreshwa:
Kubikorwa byiza, birasabwa kongeramo nyuma yo kuyungurura.Ubwinshi bwamazi akoreshwa biterwa ahanini na sisitemu yo gusaba.Umukoresha agomba kumenya umubare mwiza mugeragezwa mbere yo gukoresha.s.

gupakira no gutwara

B. Iki gicuruzwa gishobora gukoreshwa, 200KG, 1000KG ya plastike.
C. Ububiko bufunze ahantu hakonje, humye kandi hafite umwuka.Ibikoresho bigomba gufungwa neza nyuma yo gukoreshwa mbere yo kubikoresha.
D. Iki gicuruzwa kigomba gufungwa neza mugihe cyo gutwara kugirango wirinde ubushuhe, alkali na aside, imvura nindi myanda ivanze.
