Cov keeb kwm ntawm PS phab ntsa panels taug qab rov qab mus rau kev tsim kho thaum ntxov thiab siv cov khoom siv polystyrene. Raws li cov khoom siv hluavtaws, polystyrene (PS) tau ua tiav loj - teev ntau lawm nyob rau hauv nruab nrab-20th caug xyoo. Vim nws lub teeb yuag, yooj yim ntawm kev ua, thiab tus nqi qis, nws tau pib dav siv hauv ntim thiab cov khoom siv ua ntej maj mam nthuav dav mus rau hauv kev kho vaj tsev kho kom zoo nkauj, qhov chaw uas nws tau ua cov khoom siv rau phab ntsa.
Nrog rau kev loj hlob ntawm kev lag luam tsim sab hauv, cov kev txwv ntawm cov tsoos ntoo thiab xim -tshwj xeeb yog hais txog kev tsim kho kom zoo thiab tus nqi- tau tshwm sim ntau dua. Yog li ntawd, PS phab ntsa vaj huam sib luag tau pib nrhiav kev siv tswv yim hauv kev kho vaj tse sab hauv lub sijhawm tom qab ib nrab ntawm lub xyoo pua 20th. Cov khoom lag luam thaum ntxov tsom feem ntau ntawm cov txheej txheem saum npoo av thiab cov khoom siv kho kom zoo nkauj yooj yim, aiming los daws cov teeb meem xws li cov phab ntsa tsis sib luag, tsis muaj dej tsis zoo, thiab xav tau kev txhim kho sai; concurrently, cov khoom no maj tau traction nyob rau hauv ob qho tib si coj mus muag qhov chaw thiab nyob rau hauv lub interiors.
PS phab ntsa panels tau dhau los ua kev hloov kho tas mus li ntawm cov txheej txheem tsim khoom thiab tsim kom zoo nkauj. Cov txheej txheem saum npoo tau dhau los ua ntau yam sib txawv, thiab cov qauv tsim tau hloov zuj zus los ntawm cov ntaub ntawv yooj yim mus rau qib siab micro-foamed lossis cov qauv sib xyaw. Tsis tas li ntawd, cov yam ntxwv ua haujlwm tau zoo-xws li kev sib xyaw ua ke zais cov kab txuas txuas thiab cov tshuab ua haujlwm sib txuas ua ke- tau nce mus rau hauv lawv cov qauv tsim. Niaj hnub no, PS phab ntsa vaj huam sib luag tsis yog tsuas yog cov khoom siv kho kom zoo nkauj xwb tab sis kuj muaj txiaj ntsig zoo sib npaug ntawm qhov zoo nkauj nrog kev sib koom ua ke, tsim lawv tus kheej ua ib qho kev xaiv thiab nrov hauv cov khoom siv kho kom zoo nkauj sab hauv.
