Khoom Taw Qhia thiab Nta
Styrene, yog cov organic sib xyaw, cov mis nyuj yog C8H8, insoluble hauv ethancle hauv cov khoom hluavtaws, ion txauv roj hmab thiab roj hmab hluavtaws.
kev siv
Cov roj hmab tseem ceeb tshaj plaws yog ua hluavtaws roj hmab thiab monomer yas, siv los tsim cov kauj ruam butadiene, polystyrene ua npuas ncauj; Nws tseem siv rau copolymerize nrog lwm cov monomers ua rau engineing plastics ntawm kev siv sib txawv. Xws li acrylonitrile, butadiene copolymer Abs cob, siv ntau yam ntawm cov khoom siv hauv tsev thiab kev lag luam; San Copolymerized nrog Acrylonitrile yog lub resin nrog cuam tshuam tsis kam thiab ci xim. SBS capolymerized nrog Butadiene yog hom ntawm thermoplastic roj hmab, siv dav ua polyvinyl chloride, polypropylene hloov kho.
Styrene feem ntau yog siv nyob rau hauv kev tsim cov khoom styrene series thiab cov tshuaj sib pauv khoom, kuj tseem siv tau rau hauv cov chaw tshuaj, zas xim, zas xim, tshuaj tua kab thiab cov ntxhia thiab lwm yam kev lag luam. 3. Kev Siv:
Rau kev ua tau zoo tshaj plaws, nws pom zoo kom ntxiv tom qab dmution. Tus nqi ntawm cov dej siv nyob ntawm cov feem ntau ntawm daim ntawv thov system. Tus neeg siv yuav tsum txiav txim siab tus nqi zoo tshaj plaws los ntawm kev sim ua ntej siv.S.
Pob Thiab Thauj
B. Cov khoom lag luam no tuaj yeem siv, 200kg, 1000kg yas roj hmab.
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
