Khoom siv
Siv rau hauv kev tsim cov roj hmab, yas, thiab polymers.
a) Ntau lawm: expandable polystyrene (EPS);
b) Kev tsim cov polystyrene (HIPS) thiab GPPS;
c) Kev tsim cov styrenic co-polymers;
d) Kev tsim cov khoom siv tsis zoo polyester resins;
e) Kev tsim cov roj hmab styrene-butadiene;
f) Kev tsim cov styrene-butadiene latex;
g) Kev tsim cov styrene isoprene co-polymer;
h) Kev tsim cov styrene raws li polymeric dispersions;
i) Kev tsim cov polyols puv.Styrene feem ntau yog siv los ua monomer rau kev tsim cov polymers (xws li polystyrene, lossis qee yam roj hmab thiab latex)
Styrene monomer (SM), los yog vinylbenzene, ethenylbenzene los yog phenylethene yog cov mis mos molecular C6H5CH = CH2.SM yog ib qho khoom siv roj ntsha uas vaporises yooj yim, tsis muaj xim thiab muaj cov xim oily.Hauv qhov me me, qhov tsw qab ntxiag;Txawm li cas los xij, ntawm qhov loj dua, qhov tsw yuav tsis zoo.SM yog ib qho tseem ceeb hauv kev lag luam yas.
