Khoom taw qhia thiab nta
Styrene, yog cov organic compound, tshuaj formula yog C8H8, electron vinyl thiab benzene nplhaib conjugate, insoluble nyob rau hauv dej, soluble nyob rau hauv ethanol, ether thiab lwm yam organic solvents, yog ib qho tseem ceeb monomer ntawm hluavtaws cob, ion pauv resin thiab hluavtaws roj hmab.
siv
Qhov tseem ceeb tshaj plaws yog siv los ua cov roj hmab hluavtaws thiab cov yas monomer, siv los tsim cov roj hmab styrene butadiene, polystyrene, polystyrene ua npuas ncauj;Nws kuj yog siv los copolymerize nrog lwm cov monomers los ua engineering plastics ntawm kev siv sib txawv.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 khoom siv nrog kev cuam tshuam thiab xim ci.SBS copolymerized nrog butadiene yog ib hom roj hmab thermoplastic, dav siv los 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 txauv resin thiab tshuaj, ntxiv rau, styrene kuj tseem siv tau rau hauv kev siv tshuaj, tshuaj zawv plaub hau, tshuaj tua kab thiab tshuaj ntxhia. thiab lwm yam kev lag luam.3. Kev siv:
Rau kev ua tau zoo tshaj plaws, nws raug nquahu kom ntxiv tom qab dilution.Tus nqi ntawm cov dej siv feem ntau nyob ntawm daim ntawv thov system.Tus neeg siv yuav tsum txiav txim siab qhov zoo tshaj plaws los ntawm kev sim ua ntej siv.s.
pob thiab thauj
B. Cov khoom no tuaj yeem siv tau, 200KG, 1000KG yas chim.
C. Khaws ntim rau hauv qhov chaw txias, qhuav thiab qhov cua nyob hauv tsev.Cov thawv ntim khoom yuav tsum tau muab kaw kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum raug kaw kom zoo thaum lub sijhawm thauj mus los kom tsis txhob ya raws, muaj zog alkali thiab acid, nag thiab lwm yam impurities los ntawm kev sib xyaw.
