Cov hom foaming agents siv nyob rau hauv lub thawv txias muaj xws li polyurethane foaming agents, polyurethane dub thiab dawb foaming agents, polyether polyol ua ke cov ntaub ntawv, thiab lwm yam. Cov foaming agents no mas siv rau thermal rwb thaiv tsev ntawm cov thawv tub yees los txhim kho kev ua tau zoo thiab efficiency ntawm ntim. Piv txwv li, polyurethane foaming tus neeg sawv cev yog cov khoom siv uas nquag siv uas tuaj yeem nthuav dav los ntawm cov tshuaj tiv thaiv los tsim cov pores zoo, yog li muab cov rwb thaiv tsev zoo. Tsis tas li ntawd, polyurethane dub thiab dawb foaming agents thiab polyether polyol ua ke cov ntaub ntawv kuj tseem ceeb cov ntaub ntawv rau thermal rwb thaiv tsev ntawm lub tub yees. Lawv tsim cov pores zoo los ntawm kev sib txawv ntawm lub cev lossis tshuaj lom neeg kom ua tiav lub hom phiaj ntawm thermal rwb thaiv tsev.
Kev xaiv thiab kev siv cov tshuaj foaming no tsis yog tsuas yog cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ntawm cov thawv txias, tab sis kuj rau kev tiv thaiv ib puag ncig thiab kev ruaj ntseg. Piv txwv li, qee tus neeg ua npuas dej tuaj yeem muaj cov tshuaj uas tsim kev puas tsuaj rau ozone txheej, yog li yuav tsum tau saib xyuas tshwj xeeb rau kev tiv thaiv ib puag ncig thaum siv cov tshuaj foaming no. Hauv kev teb rau qhov teeb meem no, Ministry of Ecology thiab Ib puag ncig tau tshaj tawm cov lus tshaj tawm txog kev txwv tsis pub siv HCFC-141b ua tus neeg ua npuas dej hauv kev tsim cov tub yees thiab lub tub yees, lub thawv tub yees, lub tshuab rhaub dej, thiab lwm yam. , txhawm rau txhawb txoj kev loj hlob thiab kev siv ntau dua ib puag ncig tus phooj ywg technologies.
Tsis tas li ntawd, nrog rau kev nce qib ntawm cov cuab yeej technology thiab kev txhim kho ntawm kev tiv thaiv ib puag ncig, ntau tus phooj ywg ib puag ncig thiab ua tau zoo foaming agents yuav raug tsim thiab siv rau yav tom ntej kom tau raws li cov kev xav tau ntawm cov khoom siv xws li cov thawv txias.
