Kev ntsuas hluav taws

Jul 25, 2023 Tso lus

Tam sim no, muaj tsib qib tseem ceeb tiv thaiv hluav taws rau cov khoom siv hluav taws kub:

Qib A: Cov khoom siv hauv tsev uas tsis tshua muaj hluav taws kub thiab kub.

Qib A1: Tsis-combustible, tsis qhib nplaim taws.

Qib A2: Tsis-combustible, ntsuas pa luam yeeb, yuav tsum dhau cov qauv.

Qib B1: Cov khoom siv hluav taws xob hluav taws xob hauv tsev: Cov ntaub ntawv nplaim hluav taws muaj hluav taws zoo. Lawv yog ib qho nyuaj rau ignite nyob rau hauv lub xub ntiag ntawm ib tug qhib nplaim taws los yog nyob rau hauv high-temperature mob, thiab lawv tsis propagate sai. Lub combustion tam sim ntawd nres thaum lub ignition qhov chaw raug tshem tawm.

Qib B2: Cov khoom siv hluav taws xob hauv tsev: Cov khoom siv hluav taws xob muaj cov nplaim hluav taws kub. Lawv yuav ignite thiab hlawv tam sim ntawd thaum raug hluav taws kub los yog nyob rau hauv high-temperature tej yam kev mob, thiab lawv muaj peev xwm ua tau yooj yim rau kev sib kis ntawm hluav taws, xws li ntoo kab, ntoo thav duab, ntoo beam, ntoo ntaiv, thiab lwm yam.

Qib B3: Cov khoom siv hluav taws xob hauv tsev zoo heev uas tsis muaj cov nplaim hluav taws kub hnyiab, tsis tshua muaj hluav taws kub, thiab hluav taws kub hnyav.

Tsis tas li ntawd, cov qib tiv thaiv hluav taws rau cov ntaub ntawv yuav txawv raws li cov qauv sib txawv:

DIN4102: A1, A2, B1, B2, B3

EN13501-1: A1, A2, B, C, D, E, F

Cov ntaub ntawv ntxiv:

Cov khoom siv hluav taws kub-resistant yog cov uas muaj peev xwm tiv thaiv lossis tiv thaiv kev sib kis ntawm cov nplaim taws. Lawv tuaj yeem muab faib ua cov ntaub ntawv tsis-combustible thiab nplaim-retardant cov ntaub ntawv. Cov ntaub ntawv uas tsis yog-combustible tsis hlawv, thaum nplaim-retardant cov ntaub ntawv, txawm combustible, pom nplaim retardancy, ua rau nws nyuaj rau ignite los yog char. Thaum lub ignition qhov chaw raug tshem tawm, lawv combustion nres tam sim ntawd. Yog li ntawd, lawv tseem hu ua nplaim-retardant cov ntaub ntawv.

Nyob rau hauv cov ntaub ntawv ntawm cov nplaim-retardant cov ntaub ntawv, tshwj tsis yog ntawm ob peb yam uas inherently muaj nplaim-retardant zog, feem ntau, cov ntaub ntawv flammable yog kho nrog nplaim retardants, hluav taws-resistant impregnating agents, los yog hluav taws-resistant coatings kom tiav nplaim retardancy. Los ntawm qhov kev xav ntawm kev nyab xeeb hluav taws, nws raug nquahu kom siv cov khoom siv hluav taws xob tsis zoo ntawm cov khoom siv hluav taws xob hauv kev tsim hluav taws xob thiab kev tsim kho kom txo tau qhov hluav taws kub thiab txo qhov hluav taws kub. Qhov kev ua tau zoo ntawm cov khoom siv hluav taws kub yog txiav txim siab los ntawm cov kev ntsuam xyuas sib xyaw ua ke raws li kev siv sib txawv.

Inorganic binders feem ntau siv xws li iav dej, gypsum, phosphates, thiab cement.

Cov hluav taws kub-resistant ntxhia muaj xws li alumina, asbestos hmoov, calcium carbonate, perlite, thiab talcum hmoov.

Flame-retardant organic resins muaj xws li polyvinyl chloride (PVC), vinyl chloride, chlorinated roj hmab, chloroprene roj hmab emulsion, epoxy resin, phenolic resin, thiab lwm yam.

Nplaim-retardant additives encompass organic tebchaw uas muaj phosphorus, halogens, thiab nitrogen (xws li chlorinated paraffin, triethyl phosphate, decabromodiphenyl ether), thiab inorganic tebchaw xws li boron compounds (boric acid, zinc borate, aluminium borate), antimony compounds, aluminium compounds, thiab zirconium compounds.

Kev ua tau zoo ntawm cov khoom siv hauv tsev yog hais txog txhua qhov kev hloov pauv ntawm lub cev thiab tshuaj lom neeg uas tshwm sim thaum lawv hlawv lossis raug hluav taws. Qhov kev ua tau zoo no yog ntsuas los ntawm cov yam ntxwv xws li hluav taws kub nyhiab, nplaim hluav taws xob, kev tso tawm hluav taws xob, hluav taws xob tsim hluav taws xob, tsim hluav taws xob, kev poob phaus, thiab kev tsim cov tshuaj lom neeg. Raws li Suav lub teb chaws tus qauv GB8624-97, combustion kev ua tau zoo ntawm cov ntaub ntawv hauv tsev yog muab faib ua cov qib hauv qab no:

Qib A: Cov khoom siv hauv tsev uas tsis tshua muaj hluav taws kub thiab kub.

Qib B1: Cov khoom siv hluav taws xob hluav taws xob hauv tsev: Cov ntaub ntawv nplaim hluav taws muaj hluav taws zoo. Lawv nyuaj rau ignite nyob rau hauv lub xub ntiag ntawm ib tug qhib nplaim taws los yog nyob rau hauv lub kub kub, thiab lawv tsis propagate sai sai. Lub combustion tam sim ntawd nres thaum lub ignition qhov chaw raug tshem tawm.

Qib B2: Cov khoom siv hluav taws xob hauv tsev: Cov khoom siv hluav taws xob muaj cov nplaim hluav taws kub. Lawv yuav ignite thiab hlawv tam sim ntawd thaum raug hluav taws kub los yog nyob rau hauv high-temperature tej yam kev mob, thiab lawv muaj peev xwm ua tau yooj yim rau kev sib kis ntawm hluav taws, xws li ntoo kab, ntoo thav duab, ntoo beam, ntoo ntaiv, thiab lwm yam.

Qib B3: Cov khoom siv hluav taws xob ntau hauv tsev: Cov ntaub ntawv no tsis muaj cov nplaim hluav taws kub hnyiab, ua rau kub hnyiab heev, thiab ua rau muaj hluav taws kub heev.
