Styrene thiab daim ntawv thov

Dab tsi yog styrene

Styrene yog ib qho tseem ceeb organic chemical raw khoom, nws cov tshuaj formula yog C8H8, flammable, txaus ntshai tshuaj, los ntawm ntshiab benzene thiab ethylene synthesis.Nws yog tsuas yog siv nyob rau hauv zus tau tej cov foaming polystyrene (EPS), polystyrene (PS), ABS thiab lwm yam hluavtaws resins thiab styrene butadiene roj hmab (SBR), SBS elastomer, downstream khoom yog dav siv nyob rau hauv lub tsev rwb thaiv tsev, tsheb tsim, khoom siv hauv tsev, kev tsim khoom ua si, textile, ntawv, khau ntim thiab lwm yam lag luam.Tsis tas li ntawd, nws kuj tseem siv tau los ua tshuaj, tshuaj tua kab, zas xim, ntxhia intermediates, muaj ntau yam kev siv.Styrene derivatives yog plaub qhov loj tshaj plaws ethylene derivatives tom qab polyethylene, ethylene oxide thiab vinyl chloride, thiab kev tsim cov styrene resins yog thib ob tsuas yog polyethylene (PE) thiab polyvinyl chloride (PVC).

1. Industrial Chain

Cov yam ntxwv ntawm cov saw hlau kev lag luam styrene tuaj yeem ua tiav raws li "cov kabmob sab saud thiab cov thee, qis cov kabmob roj hmab" - cov kabmob sab saud roj av chemical kev lag luam saw thiab cov khoom siv tshuaj lom neeg kev lag luam, cov kabmob qis dua thiab cov roj hmab hluavtaws.

2.Siv

Nyob rau hauv cov dej ntws ntawm styrene rau ethylene thiab ntshiab benzene, downstream rau styrene, EPS ua npuas ncauj polystyrene, acrylonitrile - butadiene - styrene terpolymer, SBR / SBL styrene butadiene roj hmab, styrene latex li downstream dispersant.EPS, ABS thiab PS yog qhov kev xav tau loj tshaj plaws ntawm styrene, suav txog ntau dua 70%.Ntxiv rau qhov no ntawm qhov kev xav tau qis qis, styrene kuj tseem siv rau hauv kev lag luam, tshuaj zas, tshuaj tua kab, kev ua ntxhia thiab lwm yam lag luam.

EPS foamed polystyrene yog tsim los ntawm styrene thiab foaming agent additive khoom, muaj ib tug txheeb ze ntom ntawm me me, tsis muaj thermal conductivity, tsis tshua muaj dej nqus, poob siab vibration, tshav kub rwb thaiv tsev, suab rwb thaiv tsev, noo noo-pov thawj, anti-vibration, dielectric kev ua tau zoo tos. rau qhov kom zoo dua, nws tsuas yog siv rau cov khoom siv rwb thaiv tsev, cov khoom siv hluav taws xob / cov khoom siv hauv chaw ua haujlwm pob cushioning cov ntaub ntawv thiab ib zaug haus khob / thawv, thiab lwm yam.

PS polystyrene yog siv dav hauv kev lag luam teeb, tshwj xeeb tshaj yog rau kev kho kom zoo nkauj txhua hnub, teeb pom kev zoo thiab ntim khoom.Tsis tas li ntawd, polystyrene yog cov khoom siv rwb thaiv tsev zoo heev hauv cov khoom siv hluav taws xob, yog li nws tuaj yeem siv los tsim ntau yam twj paj nruag, cov cuab yeej cuab tam thiab cov xov xwm capacitive.

ABS resin yog ua los ntawm styrene, acrylonitrile, butadiene terpolymer, muaj kev cuam tshuam zoo heev, tshuaj tiv thaiv thiab hluav taws xob, yog cov khoom siv plhaub zoo heev, feem ntau yog siv hauv cov khoom siv hauv tsev / cov khoom siv hauv tsev thiab cov khoom siv, tsheb dashboard / qhov rooj / fender.
