Kev taw qhia txog khoom thiab nta
Styrene, yog ib qho organic compound, cov mis tshuaj yog C8H8, lub electron ntawm vinyl thiab benzene ring conjugate, insoluble hauv dej, soluble hauv ethanol, ether thiab lwm cov organic solvents, yog ib qho tseem ceeb monomer ntawm cov khoom siv hluavtaws, ion exchange resin thiab cov roj hmab hluavtaws.
siv
Qhov tseem ceeb tshaj plaws yog siv ua roj hmab thiab yas monomer, siv los tsim styrene butadiene roj hmab, polystyrene, polystyrene ua npuas ncauj; Nws kuj siv los copolymerize nrog lwm cov monomers los ua cov yas engineering ntawm ntau yam kev siv. Xws li nrog acrylonitrile, butadiene copolymer ABS resin, siv dav hauv ntau yam khoom siv hauv tsev thiab kev lag luam; SAN copolymerized nrog acrylonitrile yog cov resin nrog kev cuam tshuam tsis kam thiab xim ci. SBS copolymerized nrog butadiene yog ib hom roj hmab thermoplastic, siv dav ua polyvinyl chloride, polypropylene modifier.
Styrene feem ntau yog siv rau hauv kev tsim cov styrene series resin thiab styrene BUTADIene roj hmab, kuj yog ib qho ntawm cov khoom siv raw rau kev tsim cov ion pauv resin thiab tshuaj, ntxiv rau, styrene kuj tseem siv tau rau hauv kev lag luam tshuaj, zas xim, tshuaj tua kab thiab kev ua cov ntxhia thiab lwm yam lag luam.
Rau qhov ua tau zoo tshaj plaws, nws raug pom zoo kom ntxiv tom qab diluted. Qhov ntau ntawm cov dej siv nyob ntawm seb daim ntawv thov siv li cas. Tus neeg siv yuav tsum txiav txim siab qhov ntau zoo tshaj plaws los ntawm kev sim ua ntej siv.
pob khoom thiab kev thauj mus los
B. Cov khoom no siv tau, 200KG, 1000KG yas thoob.
C. Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag hauv tsev. Yuav tsum kaw cov thawv kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum tau kaw zoo thaum lub sijhawm thauj mus los kom tiv thaiv cov dej noo, alkali thiab acid muaj zog, nag thiab lwm yam tsis huv los ntawm kev sib tov.
