styrene monomer rau EPS ntau lawm
styrene monomer rau EPS ntau lawm,
Expandable polystyrene raw khoom, Styrene monomer siv hauv Expandable polystyrene, styrene siv rau EPS,
Synthetic styrene yog ib qho tseem ceeb raw khoom rau kev lag luam vim hais tias nws yog cov tshuaj 'lub tsev thaiv' los tsim ib tug ntau yam ntawm ntau yam yas thiab hluavtaws roj hmab uas muaj txiaj ntsig zoo xws li lub zog, durability, kev nplij siab, lub teeb yuag, kev nyab xeeb thiab lub zog efficiency.Qhov tseem ceeb styrene derivatives muaj xws li:
Styrene monomer feem ntau yog hloov los yog 'polymerised' rau hauv pellets uas tuaj yeem ua kom sov, fused thiab molded rau hauv cov khoom yas.
polystyrene (PE)
Kev nthuav dav polystyrene (EPS)
Acrylonitrile butadiene styrene (ABS)
styrene butadiene roj hmab (SBR)
unsaturated polyester resins
styrene butadiene latices
Yog li ntawd, yuav luag txhua tus neeg ntsib cov khoom lag luam styrene hauv qee daim ntawv txhua hnub.Cov ntaub ntawv ua nrog styrene tuaj yeem pom muaj nyob rau hauv ntau yam khoom siv xws li cov khoom noj thiab dej haus, ntim khoom, cov log tsheb, lub tsev rwb thaiv tsev, ntaub pua plag rov qab, khoos phis tawj thiab cov khoom siv fiberglass reinforced xws li nkoj hulls, surfboards thiab chav ua noj countertops.
Feem ntau ntawm cov styrene yog siv los tsim cov polystyrene rau cov khoom xws li cov khoom siv kho mob, cov khoom siv hauv tsev, khob dej qab zib, cov thawv ntim khoom noj thiab lub qhov rooj tub yees.
Expandable polystyrene
Expandable polystyrene (EPS) yog ib qho derivative siv los tsim lub teeb yuag tab sis nruj ua npuas ncauj siv hauv tsev rwb thaiv tsev, raws li cov khoom ntim tiv thaiv, xws li padding hauv tsheb kauj vab thiab maus taus kaus mom hlau thiab lub tsheb sab hauv, hauv txoj kev thiab choj kev tsim kho, thiab tsim zaj duab xis-teeb. thaj chaw.Cov khoom sib xyaw EPS kuj tseem siv tau rau hauv da dej thiab da dej enclosures, automotive lub cev panels, nkoj thiab cua turbines.
Styrene ua rau cov tuam txhab txhim kho cov khoom hauv ib txoj hauv kev uas pab: ua kom lub tsheb thiab tsheb ciav hlau sib zog thiab siv roj ntau dua;txo qhov kev cia siab ntawm cov khoom siv hluav taws xob kim xws li cov ntoo kub hnyiab, marble, granite thiab roj hmab ntuj;thiab txhim kho lub zog efficiency ntawm tsev los ntawm kev rwb thaiv tsev zoo dua.
