Taw qhia rau Polystyrene Plastics

Polystyrene yog cov yas nrog cov qauv kab uas yog polymerized los ntawm styrene monomers. Nws lub npe lag luam raug xa mus rau "benzene yas", thiab cov lus Askiv luv luv yog PS. Lub synthesis ntawm polystyrene feem ntau siv thaiv polymerization thiab emulsion polymerization.

1. bulk polymerization

Cov pob tshab pob tshab tuaj yeem tau txais los ntawm polymerizing styrene hauv cov roj inert thiab tswj qhov kub thiab txias nyob rau hauv thaj tsam ntawm 60-90 degree thiab siv dibenzoyl peroxide ua catalyst. Cov resin muaj ntau dua purity, zoo dua pob tshab thiab gloss.

2. Txoj kev emulsion

Nyob rau hauv qhov kev txiav txim ntawm lub catalyst, qhov kub ntawm aqueous emulsion ntawm styrene monomer yog tswj ntawm 80-95 degree rau polymerization, ces cov polymer yog cais los ntawm leej niam cawv, thiab cov hmoov resin yog tau tom qab kev kho mob. Lub tshav kub tsis kam ntawm cov khoom tiav yog me ntsis siab dua li ntawm cov khoom siv polymer, tab sis cov hluav taws xob rwb thaiv tsev thiab pob tshab yog me ntsis phem dua.
