Hais txog cov qauv kev lag luam, kev tsim khoom thiab kev siv cov polystyrene nthuav dav (EPS) yuav tsum ua raws li cov qauv hauv lub tebchaws thiab thoob ntiaj teb los xyuas kom meej tias nws zoo thiab kev nyab xeeb. Cov qauv no suav nrog ntau yam xws li cov khoom siv raw khoom zoo, kev tswj cov txheej txheem tsim khoom, thiab kev kuaj xyuas cov khoom lag luam. Tib lub sijhawm, nrog kev paub txog ib puag ncig, kev xav tau ntau dua tau muab tso rau ntawm kev rov ua dua thiab rov siv dua EPS, tsav kev txhim kho cov thev naus laus zis thiab kev lag luam.
Nws yog tsim nyog sau cia tias thaum EPS muaj ntau qhov zoo, nws cov khoom siv thiab kev siv kuj tseem muaj qee qhov cuam tshuam rau ib puag ncig. Yog li ntawd, thaum txhawb thiab siv EPS, nws tseem yuav tsum tau ua tib zoo saib xyuas nws cov kev ua haujlwm ib puag ncig thiab txhawb nqa kev tsim ntsuab thiab kev tsim kho kom ruaj khov. Piv txwv li, qhov tsis zoo ib puag ncig ntawm EPS tuaj yeem raug txo los ntawm kev txhim kho cov txheej txheem tsim khoom, nce cov nqi rov ua dua tshiab, thiab tsim cov kev hloov pauv ib puag ncig.
