Nrog rau kev txhim kho tshuaj lom neeg kev lag luam, polystyrene ua npuas dej tau hloov mus rau hauv kev lag luam muaj txiaj ntsig zoo dua rau kev tsim cov khoom siv rwb thaiv tsev los ntawm cov khoom ntim khoom thiab cov khoom siv khoom noj khoom siv. Cov khoom siv defoamed pov tseg polystyrene ua npuas dej yog ntxiv nrog qee yam ntau npaum li cas ntawm qhov kub npau npau kua hloov kho, ua npuas ncauj rau tus neeg sawv cev, catalyst thiab stabilizer. Tom qab cov cua sov, cov polystyrene hlaws yog prefoamed, thiab tom qab ntawd txhav polystyrene ua npuas yas yas nrog lub qhov hws zoo yog rhuab los ntawm cua sov. Cov phaj no tuaj yeem siv ib leeg, lossis nws tuaj yeem muab qhwv nrog nyias txhuas phaj tom qab sib sau los ua phaj txhuas-yas. Nws qhov kev txuag ua kom sov yog qhov zoo heev. Los ntawm kev siv cov kev sim tiag tiag ntawm lub ru tsev hauv tsev, tsis muaj qhov ntxau thiab qhov pom tshwm sim, thiab tus nqi ntawm qhov project yuav raug txo kom tsawg, thiab kev tsim ua haujlwm tau yooj yim. Yog li no, hauv thaj chaw cua sov qaum teb, polystyrene ua npuas rwb thaiv tsev pawg tsim los ntawm hom no muaj kev thov dav thiab kev cia siab zoo rau kev txhim kho.
