Fireproof Plywood yog dab tsi?

Nyob rau hauv European grading system teev nyob rau hauv European tus qauv EN135011, cov fireproof plywood qib yog D-S2. Thaum lub plywood ceev yog ntau tshaj 500kg / m3 thiab lub thickness tsis tsawg tshaj li 15 hli, qhov no fireproof qib yuav siv tau ncaj qha yam tsis muaj kev ntsuam xyuas ntxiv.
Cov kev cai hauv tsev ntawm ntau lub teb chaws tau teev cov kev cai rau kev tiv thaiv hluav taws sib txawv rau cov kev siv sib txawv. Feem ntau hais lus, cov xwm txheej rau plywood thiab nws cov qauv yuav tsum tau nthuav tawm hauv cov tsev yog tib yam li lwm cov ntoo plywood. s1-s3 sawv cev rau theem ntawm kev tsim cov pa luam yeeb, thiab d0-d3 sawv cev rau theem kev pheej hmoo ntawm cov tee hluav taws kub.
Qhov hluav taws kub tsis kam ntawm plywood tuaj yeem txhim kho los ntawm kev kho cov nplaim hluav taws xob lossis cov khoom siv tsis zoo. Cov nplaim hluav taws kub hnyiab yog cov ntsev ntau hauv cov tebchaw, uas feem ntau muaj hygroscopicity, txhais tau tias lawv nqus dej los ntawm huab cua ib puag ncig. Yog li ntawd, kev txheeb xyuas qhov ruaj khov ntawm qhov kev cia siab ntawm cov nplaim hluav taws yuav tsum tau ua nyob rau hauv tag nrho cov kev pab cuam lub neej.
