GPPS plastics yog universal qib polystyrene (GPPS), polystyrene (PS) yog ua los ntawm styrene monomer (SM) polymerization, uas tuaj yeem ua ke los ntawm ntau hom kev sib txuas. Tam sim no, bulk polymerization thiab suspension polymerization yog siv hauv kev lag luam. PS yog cov thermoplastic uas tsis yog-crystalline resin, uas feem ntau yog muab faib ua dav dav -lub hom phiaj polystyrene (PPS, feem ntau hu ua benzene-permeable), cuam tshuam-resistant polystyrene ( lub duav, feem ntau hu ua benzene hloov), thiab nthuav polystyrene (EPS).
Vim tias polystyrene yog pob tshab thiab muaj kev nruj zoo heev, hluav taws xob thiab kev luam ntawv, tshwj xeeb tshaj yog kev tu cev zoo thiab tus nqi qis, nws muaj cov ntawv thov dav hauv kev ntim khoom noj. Nws tau dav siv nyob rau hauv ntau yam twj paj nruag, lub teeb ci, qhov chaw kho qhov muag, cov khoom siv ntsuas, cov iav qhov rais pob tshab, cov qauv pob tshab, cov tshuaj kua qaub cia tso tsheb hlau luam, cov kua qaub thauj tso tsheb hlau luam, cov khoom siv sib txuas lus, cov khoom siv hluav taws xob ntau, cov khoom siv hluav taws xob ntau zaus, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob. cov khoom siv rwb thaiv tsev khov, thiab lwm yam, hauv kev lag luam mechanical thiab hluav taws xob, instrumentation, kev sib txuas lus khoom lag luam thiab lwm yam. Kuj tseem siv tau rau ntau yam khoom siv niaj hnub, xws li lub kaus mom lub raj mis, ntim khoom, kho kom zoo nkauj, khawm, zuag, txhuam hniav, xab npum, thawv luam yeeb thiab cov khoom ua si.
