Kev tsim cov styrene-acrylonitrile copolymer
tsim cov styrene-acrylonitrile copolymer,
San Plastic Raw Khoom, SAN kev loj hlob, SAN raw khoom,
Cov txheej txheem muaj xws li: (a) kev taw qhia, mus rau hauv lub reactor, [lacuna] cov tshuaj tiv thaiv sib tov uas muaj tag nrho cov dej, acrylonitrile, initiator los yog initiators, chain-transfer agent lossis agents thiab suspending agent los yog agents thiab optionally ib tug predetermined feem ntawm tag nrho. tus nqi ntawm styrene;(b) nplawm cov tshuaj tiv thaiv sib tov thiab nce qhov kub ntawm cov tshuaj tiv thaiv no mus rau 60 ° C thiab tom qab ntawd mus rau 120 ° C;(c) Thaum qhov kub ntawm cov tshuaj tiv thaiv sib tov tau mus txog 60 ° C los yog 120 ° C, qhov sib ntxiv ntawm cov nyiaj seem ntawm styrene, thiaj li ua kom cov styrene monomer / acrylonitrile monomer ratio nyob rau hauv cov tshuaj tiv thaiv sib tov thoob plaws lub sij hawm ntawm lub ntxiv;(d) nce qhov kub ntawm cov tshuaj tiv thaiv sib tov rau 140 ° C thiab kev saib xyuas ntawm qhov kub thiab txias rau lub sijhawm txaus kom coj cov copolymerization kom tiav;thiab (e) txias cov tshuaj tiv thaiv sib tov thiab rov qab los ntawm styrene/acrylonitrile copolymer.Daim ntawv thov rau kev tsim khoom ntawm SAN copolymer muaj qib ntawm acrylonitrile tsawg kawg yog 40% los ntawm qhov hnyav.
