Nrog kev txhim kho txuas ntxiv ntawm lub tsev txuag hluav taws xob, kev txuag hluav taws xob thiab hluav taws xob hluav taws xob ntawm lub tsev tsim, ua ib feem tseem ceeb ntawm lub tsev txuag hluav taws xob, tau dhau los ua ib qho tshiab ntawm kev txuag hluav taws xob hauv tsev tshawb fawb thiab kev siv hauv peb lub teb chaws.

Mineral wool feem ntau yog hais txog pob zeb wool, ntxhia wool, iav ntaub plaub, aluminium silicate wool thiab lawv cov khoom.Nws muaj me me bultity, qis thermal conductivity, zoo tshuaj ruaj khov, lub cua sov tsis kam, tiv taus kab mob.Txij li xyoo 1950, cov ntaub plaub ntxhia tau siv los ua cov rwb thaiv tsev.Tam sim no nws tau siv dav hauv ntau hom tsev, thiab cov khoom lag luam ua tiav tau tsim.Cov khoom lag luam muaj xws li kev xav, board, raj plhaub, thaiv, lev, hlua, board thiab lwm yam.Mineral wool yog lub ntsiab cua sov-insulating thiab suab-insulating khoom nyob rau hauv peb lub teb chaws kev lag luam thiab kev tsim kho.

Extruded polystyrene (XPS) yog ib yam tshiab ntawm thermal rwb thaiv tsev cov ntaub ntawv tsim tawm txawv teb chaws nyob rau hauv 1950s thiab 1960s.Nws muaj cov yam ntxwv ntawm cov thermal conductivity tsawg, tsis tshua muaj dej nqus thiab siab compressive zog.Nws thermal rwb thaiv tsev muaj nuj nqi, tshwj xeeb tsis kam rau vapor permeability, tsis tshua muaj siab compressive zog, thiab yooj yim ua thiab installation.Cov txheej txheem ntau lawm ntawm XPS yog kom sov thiab extrude cov melted polystyrene resin los yog nws cov copolymer thiab ib tug me me ntawm additives thiab foaming tus neeg saib xyuas nyob rau hauv ib tug tshwj xeeb extruder, stretch nws los ntawm ib tug siab roller thiab nyob rau hauv lub tshuab nqus tsev forming cheeb tsam (qee yam txheej txheem tsis xav tau ( Lub tshuab nqus tsev ua kom txias, daim ntawv thov ntawm XPS hauv kev tsim kho feem ntau suav nrog (1) thermal rwb thaiv tsev cov ntaub ntawv hauv cov phab ntsa sib xyaw; (2) tsim cov phab ntsa hauv av; (3) ru tsev sab hauv thiab sab nraud thermal rwb thaiv tsev; (4) ru tsev thermal rwb thaiv tsev; (5) Txoj kev loj, tshav dav hlau khiav, chaw nres tsheb thiab lwm qhov chaw uas yuav tsum tau tiv thaiv pavement re-slurry thiab yuav tsum tiv taus siab;(6) Kev cia txias thiab lwm yam khoom siv cia txias txias.
