Cov khoom siv hauv tsev siv rau kev kho kom zoo nkauj hauv tsev tuaj yeem muab faib ua plaub qib: Chav A (tsis-flammable), Chav B1 (nplaim hluav taws xob), Chav B2 (ib txwm nplaim taws), thiab Chav B3 (yooj yim tawg tau yooj yim).
Ntawm lawv, Chav B3 yog cov nplaim hluav taws kub heev, tsis muaj nplaim hluav taws kub, thiab muaj hluav taws kub heev; Class B2 muaj cov nplaim hluav taws kub. Yog tias muaj cov nplaim liab qab lossis kub kub, nws yuav hlawv.the Class B1 muaj cov nplaim hluav taws kub hnyiab. Nyob rau hauv qhov kev tshwm sim ntawm ib tug liab qab nplaim taws los yog kub siab, hluav taws yuav tsis kis sai sai tom qab hlawv. combustion yuav cuam tshuam thiab nres thaum lub hauv paus ntawm ignition raug tshem tawm.
Cov hlau carved sanwich phab ntsa panels siv cov khoom siv hluav taws xob, thiab nws qhov kev ua tau zoo ntawm kev sib txuas yog siab dua, uas tuaj yeem ncav cuag B1 qib. Xa mus rau cov qauv tsim nyog ntawm GB / T8626, raws li kev sim, cov khoom siv hluav taws xob tiv thaiv hluav taws yuav tsis ua rau cov ntawv lim yuav raug hluav taws kub hnyiab. Kev xa mus rau cov qauv tsim nyog ntawm GB / T8625, raws li kev sim, qhov nruab nrab qhov seem seem ntawm pawg hlau carved vaj huam sib luag yog ntau dua 15 cm, thiab qhov nruab nrab kub ntawm cov pa roj flue yog nyob rau hauv 200 degree . Kev xa mus rau cov qauv tsim nyog ntawm GB / T8627, raws li kev sim, qhov ntsuas pa taws ntom ntom (SDR) ntawm cov hlau engraved board yog qis dua 75. Cov ntaub ntawv yog cov ntaub ntawv pov thawj zoo ntawm qib combustion ntawm cov hlau carved board. , yog li cov hlau carved sanwich phab ntsa panels kuj tseem hu ua fireproof hlau phaj. Nws daim ntawv thov tau ua lub luag haujlwm zoo heev hauv kev txhim kho qhov hluav taws kub thiab hluav taws kub ntawm phab ntsa.
Los ntawm cov lus qhia saum toj no, koj yuav paub qhov txawv ntawm qhov hluav taws kub ntawm cov khoom siv hauv tsev, thiab raws li koj xav tau, xaiv qhov hluav taws kub ntawm cov sandwich phab ntsa panels koj xav tau.
