Kev nthuav dav polystyrene ntim, tseem hu ua EPS, yog cov khoom ntim nrov siv los ntawm ntau lub lag luam thoob ntiaj teb. Lub teeb yuag thiab ntau yam khoom siv no yog tsim los ntawm kev nthuav dav polystyrene ua npuas ncauj, uas yog tsim los ntawm tshuab cua rau hauv cov hlaws kub polystyrene. Qhov tshwm sim yog cov khoom lag luam nruj, lub teeb yuag, thiab cov khoom siv ruaj khov uas zoo meej rau kev ntim khoom ntau yam, los ntawm cov khoom siv hluav taws xob mus rau cov khoom noj.

Ib qho txiaj ntsig tseem ceeb ntawm EPS ntim khoom yog nws lub peev xwm los tiv thaiv cov khoom los ntawm kev puas tsuaj thaum thauj thiab khaws cia. Ua tsaug rau nws cov khoom muaj zog-nqus tau zoo, EPS ntim tuaj yeem ua rau cov khoom muag muag thiab tiv thaiv lawv kom tsis txhob muaj kev sib tsoo lossis jostled thaum caij tsheb npav. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom uas yooj yim puas, xws li iav, khoom siv hluav taws xob, thiab cov khoom tawg yooj yim.
EPS ntim kuj zoo heev rau rwb thaiv tsev. Vim nws cov thermal conductivity tsawg, nws tuaj yeem khaws cov khoom ntawm qhov kub thiab txias thaum lub sij hawm xa khoom thiab khaws cia, uas yog ib qho tseem ceeb rau cov khoom uas yuav tsum tau tswj qhov kub thiab txias, xws li tshuaj los yog cov khoom puas tsuaj. EPS ntim kuj tseem tuaj yeem pab txo qis kev siv hluav taws xob thaum lub sijhawm thauj mus los, vim nws tsis tas yuav siv tub yees ntau npaum li lwm cov khoom ntim.
Lwm qhov zoo ntawm EPS ntim khoom yog nws qhov cuam tshuam ib puag ncig. Txawm hais tias qee tus tuaj yeem thuam nws cov txheej txheem tsim khoom, nws tuaj yeem rov ua dua thaum kawg ntawm nws lub neej muaj txiaj ntsig, uas pab txo cov khoom pov tseg thiab txuag cov peev txheej. Nws kuj tseem muaj cov pa roj carbon tsawg dua li lwm cov ntaub ntawv, xws li yas lossis ntawv, vim nws lub teeb yuag thiab siv tau zoo.
Hauv kev xaus, EPS ntim khoom yog cov khoom ntim zoo thiab muaj ntau yam nrog ntau cov txiaj ntsig. Nws muab kev tiv thaiv zoo heev rau cov khoom thaum thauj thiab khaws cia, muab rwb thaiv tsev rau cov khoom kub-rhiab, thiab muaj kev cuam tshuam ib puag ncig piv rau lwm cov ntaub ntawv. Thaum siv lub luag haujlwm, nws tuaj yeem yog cov cuab yeej tseem ceeb rau cov lag luam tab tom nrhiav los txhim kho lawv cov khoom ntim khoom thaum lub sijhawm
