EPS yog lub teeb yuag polymer.Vim nws tus nqi qis, nws kuj yog cov khoom siv dav siv ntau tshaj plaws hauv kev ntim khoom, suav txog ze li 60%.Polystyrene resin yog tsim los ntawm kev ntxiv foaming tus neeg sawv cev los ntawm pre-foaming, curing, molding, ziab, txiav thiab lwm yam txheej txheem.Cov kab noj hniav kaw ntawm EPS txiav txim siab tias nws muaj qhov zoo thermal rwb thaiv tsev thiab thermal conductivity tsawg.Lub thermal conductivity ntawm EPS boards ntawm ntau yam specifications yog nruab nrab ntawm 0.024W / mK ~ 0.041W / mK Nws muaj kev txuag hluav taws xob zoo thiab kev txuag txias hauv kev lag luam.
Txawm li cas los xij, raws li cov khoom siv thermoplastic, EPS yuav yaj thaum cua sov thiab ua kom khov thaum txias, thiab nws cov thermal deformation kub nyob ib ncig ntawm 70 ° C, uas txhais tau hais tias EPS incubators ua tiav rau hauv npuas ntim yuav tsum tau siv qis dua 70 ° C.Yog tias qhov kub thiab txias siab dhau, 70 ° C, lub zog ntawm lub thawv yuav raug txo, thiab cov tshuaj lom neeg yuav raug tsim tawm vim yog volatilization ntawm styrene.Yog li ntawd, EPS pov tseg tsis tuaj yeem raug huab cua tsis zoo, thiab tsis tuaj yeem raug hlawv.
Tsis tas li ntawd, qhov nyuaj ntawm EPS incubators tsis zoo heev, kev ua haujlwm cushioning kuj yog dav dav, thiab nws yooj yim rau kev puas tsuaj thaum lub sijhawm thauj mus los, yog li nws feem ntau yog siv rau kev siv ib zaug, rau lub sijhawm luv luv, luv luv. saw tsheb thauj mus los, thiab kev lag luam khoom noj xws li nqaij thiab nqaij qaib.Cov tais thiab cov khoom ntim khoom noj ceev.Lub neej kev pab cuam ntawm cov khoom no feem ntau luv luv, li ntawm 50% ntawm cov khoom Styrofoam muaj lub neej kev pab tsuas yog 2 xyoo, thiab 97% ntawm cov khoom Styrofoam muaj kev pab cuam lub neej ntawm tsawg tshaj li 10 xyoo, ua rau EPS ua npuas ncauj yuav tsum tau muab pov tseg xyoo. los ntawm xyoo, Txawm li cas los,EPS ua npuas ncaujNws tsis yooj yim rau decompose thiab rov siv dua, yog li nws yog qhov ua txhaum loj ntawm cov pa phem dawb tam sim no: EPS suav rau ntau dua 60% ntawm cov khib nyiab dawb hauv dej hiav txwv!Raws li cov khoom ntim ntawm EPS, feem ntau HCFC foaming agents yog siv rau hauv cov txheej txheem foaming, thiab feem ntau cov khoom yuav muaj ntxhiab tsw.Lub peev xwm ozone depletion ntawm HCFCs yog 1,000 npaug ntawm carbon dioxide.Yog li ntawd, txij li xyoo 2010, United Nations, Tebchaws Meskas, European Union, Tuam Tshoj, Kaus Lim Qab Teb, Nyiv thiab lwm lub tebchaws muaj feem cuam tshuam (cov koom haum) thiab cheeb tsam tau dhau txoj cai txwv lossis txwv tsis pub siv cov yas siv ib zaug, suav nrog Styrofoam. , thiab tib neeg tau yuam kom tsim "Revised Roadmap".
