Txoj cai ntawm waterproof thiab breathable membrane
Nyob rau hauv lub xeev ntawm cov dej vapor, cov dej hais tau zoo heev, thiab raws li lub hauv paus ntsiab lus ntawm capillary zog, lawv muaj peev xwm mus rau hauv lub capillary smoothly nkag mus rau sab nraud (hauv peb cov khoom, lawv tuaj yeem dhau los ntawm cov txheej txheem yas hauv nruab nrab) , thiab tom qab ntawd vapor permeability tshwm sim. Thaum cov dej vapor condenses rau hauv cov tee dej, cov khoom ua loj dua. Vim yog cov nyhuv ntawm qhov nro ntawm cov tee dej (cov dej molecules "rub thiab sib tw" nrog rau ib leeg), cov dej molecules tsis tuaj yeem sib cais los ntawm cov tee dej thiab nkag mus rau sab nraud, uas yog kom tsis txhob muaj kev nkag mus ntawm cov dej. dej tshwm sim, yog li ntawd lub vapor permeable membrane muaj kev ua haujlwm ntawm waterproofing.
Waterproof thiab breathable membrane khoom
Kev siv tshuab ntawm cov dej tsis zoo thiab ua tsis taus pa yog thawj zaug los ntawm cov teb chaws Europe thiab Asmeskas. Txawm li cas los xij, cov txheej txheem tsim khoom ntawm cov khoom siv hauv tsev muaj ntau yam, thiab cov khoom zoo los ntawm ntau lub tuam txhab sib txawv, ua tsis tau raws li tus qauv zoo ib yam. Qhov tseeb, cov dej tsis zoo thiab ua tsis taus pa feem ntau muaj peb txheej: PP spunbonded non-woven fabric, PE polymer breathable membrane, thiab PP spunbonded non-woven fabric. Cov nyhuv ntawm spunbonded non-woven npuag yog tsuas yog los txhim kho lub tensile quab yuam thiab hydrostatic siab thiab tuav lub hauv paus txheej (breathable membrane). Qhov tiag breathability feem ntau yog nyob ntawm PE polymer breathable membrane nyob rau hauv nruab nrab txheej.
Tus nqi ntawm waterproof thiab breathable membrane
Tus nqi ntawm waterproof thiab breathable membrane mas muaj raw cov ntaub ntawv, ntau lawm txheej txheem, thiab cov cuab yeej peev peev. Tam sim no, qee cov tuam txhab lag luam hauv Suav teb hais tias cov dej tsis muaj dej thiab ua tsis taus pa yog cov khoom siv pabcuam, tus nqi qis heev, tus nqi qis, thiab nws tsis siab dua cov khoom tseem ceeb xws li rwb thaiv tsev paj rwb. Qhov no tsis muaj tseeb. Qhov kev hais lus zoo li no yog kev nkag siab thiab ua rau cov neeg siv khoom yuam kev. Vim tias cov tuam txhab lag luam no tsis paub txog cov txheej txheem tsim cov dej tsis zoo thiab ua tsis taus pa ntawm txhua qhov, lawv siv cov ntaub ntawv tsis zoo-coated non-woven fabrics los yog kub-melt nplaum spraying composite non-woven npuag khoom los tsim cov khoom cuav thiab shoddy waterproof thiab breathable membranes, kev dag ntxias cov neeg siv khoom nrog fallacies, kom ua tiav ulterior motives.
