Fireproof plywood muaj qhov ntsuas hluav taws kub. Kev ntsuas hluav taws kub yog qhov taw qhia tseem ceeb rau kev ntsuas qhov ua tau zoo ntawm kev sib txuas thiab hluav taws kub tsis kam ntawm cov khoom hauv hluav taws. Rau qhov hluav taws kub-resistant plywood, nws qhov ntsuas hluav taws kub feem ntau yog txiav txim siab raws li cov qauv sib txawv thiab cov qauv kev sim.
Nyob rau hauv Suav teb, raws li "Kev faib tawm thiab kev cim kev cai rau hlawv tus cwj pwm ntawm cov khoom siv hauv tsev" GB8624-2012, qhov ntsuas hluav taws kub ntawm cov plywood tuaj yeem yog B1 lossis B2. B1 qib hluav taws-resistant plywood yog cov khoom siv hluav taws xob uas tuaj yeem tiv taus qee lub sijhawm hauv qhov hluav taws kub tsis muaj hluav taws kub los yog kub hnyiab heev, tiv thaiv kev sib kis ntawm hluav taws. B2 qib fireproof plywood belongs rau cov ntaub ntawv uas tsis yog flammable, tab sis nws tseem muaj peev xwm hlawv nyob rau hauv tej yam kev mob. Nws qhov combustion tsis yog khaus heev, thiab nws tsis yooj yim ua rau hluav taws kub hnyiab tau sai heev hauv lub sijhawm luv luv.
Tsis tas li ntawd, raws li European grading system teev nyob rau hauv tus qauv EN135011, hluav taws-resistant plywood kuj muab faib mus rau hauv cov qib sib xws. Piv txwv li, thaum qhov ceev ntawm plywood yog ntau tshaj 500kg / m³ thiab lub thickness tsis tsawg tshaj li 15 hli, nws qhov hluav taws kub ntsuas yuav siv tau ncaj qha yam tsis muaj kev ntsuam xyuas ntxiv. Nyob rau tib lub sijhawm, tus qauv kuj tseem qhia txog qib ntawm kev tsim cov pa luam yeeb (s1-s3) thiab theem kev pheej hmoo ntawm cov tee hluav taws kub (d0-d3) txhawm rau txheeb xyuas qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob hluav taws xob.
Nws yuav tsum raug sau tseg tias qhov ntsuas hluav taws kub ntawm cov khoom siv hluav taws xob tsis yog qhov tseeb, thiab nws cuam tshuam los ntawm ntau yam xws li cov khoom siv, cov txheej txheem ntau lawm, txheej txheej, thiab kev siv ib puag ncig. Yog li ntawd, thaum xaiv cov plywood tiv taus hluav taws, ntxiv rau kev saib xyuas nws qhov kev ntsuas hluav taws, lwm yam yuav tsum tau ua kom tiav los xyuas kom meej nws txoj kev nyab xeeb thiab kev ntseeg siab hauv kev siv tswv yim.
Nyob rau hauv luv luv, hluav taws-resistant plywood muaj sib txawv hluav taws kev ntaus nqi, uas yog txiav txim los ntawm txawv cov qauv thiab kev xeem txoj kev. Thaum xaiv thiab siv cov plywood tiv taus hluav taws, qhov ntsuas hluav taws xob tsim nyog thiab cov khoom siv yuav tsum raug xaiv raws li cov xwm txheej tshwj xeeb thiab cov kev xav tau.
