Ua ntej tshaj plaws, peb yuav tsum nkag siab txog lub hauv paus ntsiab lus ntawm kev cuam tshuam iav. Impact iav muaj ib qho tshwj xeeb polymer zaj duab xis sandwiched ntawm ob txheej iav. Thaum lub iav raug quab yuam, lub khob yuav tawg, tab sis cov txheej txheem polymer sab hauv yuav ua rau cov iav shards tsis ya, yog li tswj kev ncaj ncees ntawm cov iav. Impact iav yog tsuas yog siv nyob rau hauv tshwj xeeb zaus xws li anti-tub sab tub nyiag thiab tawg-pov thawj, tab sis nws kuj yuav siv tau nyob rau hauv lub suab rwb thaiv tsev thiab kub preservation ntawm iav qhov rais.
Qhov thib ob, muaj peb txoj hauv kev ntawm iav qhov rais hloov hluav taws xob: conduction, convection thiab hluav taws xob. Lub qhov rais iav feem ntau absorbs cua sov los ntawm high-kub sab nraum zoov los ntawm hluav taws xob, thiab ces hloov lub tshav kub mus rau hauv chav tsev los ntawm conduction thiab convection, uas ua rau ib tug nce nyob rau hauv lub tsev kub.
Thaum lub qhov rais cuam tshuam raug ntsia rau ntawm lub qhov rais iav, cov yeeb yaj kiab tshwj xeeb polymer ntawm cov txheej sab hauv ntawm cov iav cuam tshuam tsim cov txheej txheej insulating uas txo cov cua sov. Lub thermal rwb thaiv tsev kev ua tau zoo ntawm qhov cuam tshuam qhov rais feem ntau yog los ntawm cov khoom siv thiab cov tuab ntawm cov yeeb yaj kiab polymer sab hauv, thiab nws cov thermal rwb thaiv tsev ua haujlwm zoo ib yam li cov iav qhov rais. Tau kawg, yog tias qhov cuam tshuam qhov rais yog insulating ntau dua, nws yuav ua tau zoo dua ntawm kev txo cov cua sov.
Tsis tas li ntawd, yog tias lub qhov rais iav nws tus kheej muaj qee qhov thermal rwb thaiv tsev, qhov cuam tshuam qhov rais tuaj yeem txhim kho nws cov thermal rwb thaiv tsev. Nyob rau hauv cov ntaub ntawv no, lub thermal rwb thaiv tsev cov khoom ntawm qhov cuam tshuam qhov rais thiab glazing ua hauj lwm ua ke kom zoo txo cua sov hloov.
Txhawm rau ua kom tiav, qhov cuam tshuam qhov rais tuaj yeem txo lub peev xwm ntawm cov iav qhov rais kom xa cov cua sov mus rau ib qho twg. Txawm li cas los xij, thermal rwb thaiv tsev kev ua tau zoo ntawm qhov cuam tshuam qhov rais yog qhov tsis muaj zog, thiab qhov kub tsis tuaj yeem tsuas yog txo qis rau qee yam.
