Feem ntau muab cov khawb av muaj txog 20-40% thinner tshaj li woven cov khoom ua los ntawm tib lub xov thiab nrog kev tsim kho ib yam.
Ntau cov qauv hauv European yuav tsum tau rau lub ru tsev membranes cov khoom tsawg kawg ntawm cov khoom seem ntawm ob sab ntawm cov khawb. Muab cov khawb av pab kom tsim cov khoom thinner yam tsis muaj kev lees txais cov txiaj ntsig kev ua haujlwm. Nws yog ua tau kom txuag tau ntau dua 20% ntawm raw cov ntaub ntawv xws li PVC lossis PVOH.
Tsuas yog clims tso cai cov khoom lag luam ntawm ib qho zoo heev symmetrical peb txheej av membrane (1.2 hli) uas feem ntau siv nyob rau hauv Central Europe. Cov ntaub siv tsis tuaj yeem siv rau cov vaj tsev mis uas yog tus nqi dua 1.5mm.
Tus qauv ntawm cov tso rau ntawm cov tso tawm yog pom tsawg dua hauv cov khoom kawg tshaj li cov qauv ntawm cov ntaub ntawv woven. Qhov no ua rau smoother thiab ntau txawm txawm saum npoo ntawm cov khoom kawg.
Cov smoother saum npoo ntawm cov khoom kawg uas muaj tso cov txhuam kom tso cai rau weld lossis kua nplaum txheej ntawm cov khoom kawg tau yooj yim thiab ua haujlwm sib.
Cov chaw smoother yuav tiv taus cov av ntev dua thiab ua ntu zus ntau dua.
