Cov khoom lag luam EPS siv cov cua sov kom nthuav dav thiab ua npuas cov khoom siv EPS, uas yog kev hloov pauv lub cev. Hauv kev ua npuas thiab ua mould theem, EPS yuav tso cov pa nkev pov tseg me me, thiab nws cov khoom tseem ceeb yog benzene series thiab pentane foaming agent.
EPS muaj tshuaj lom neeg ruaj khov thiab tiv tshav kub. Nws qhov kub pyrolysis ntau dua li ua npuas dej, ua pwm thiab ziab. Raws li qhov xwm txheej ib txwm muaj, nws yuav tsis ua rau kev sib tawg ntawm cov khoom thiab cov tswv yim yuav tsis tsim cov benzene monomer pov tseg roj.
Nyob rau hauv qhov kev txiav txim ntawm kev quab yuam, me me ntawm cov molecules yuav tawg, decomposed, degraded, thiab lwm yam. Yog li ntawd, yuav muaj qhov tsawg me me ntawm cov benzene monomers dawb thiab cov ntsiab lus kub npau ntxiv thaum lub sijhawm ua npuas dej. Cov tshuaj tsis haum yog tsim tawm.
Hauv cov txheej txheem ua npuas thiab ua kom sov, EPS yuav dhau mus ua qhov tsim tawm kom tsim tau me me ntawm cov pa roj carbon molecular qis (feem ntau yog pentane) vim cua sov.
