Galvanized thav duab tawg-pov thawj cua ntxuam rau rhiav pa taws tso pa tawm

Cov ntsiab lus ntawm cov khoom tawg-pov thawj: cov khoom siv hluav taws xob uas yuav tsis ua rau hluav taws kub hnyiab hauv ib puag ncig tawg nyob rau hauv cov xwm txheej tshwj xeeb.
Cov khoom tawg-pov thawj muaj qib tawg-pov thawj, thiab cov ntaub ntawv tawg-pov thawj thiab siv sijhawm ntawm cov khoom tuaj yeem pom los ntawm qib tawg-pov thawj.Piv txwv li, qhov tawg-pov thawj theem ntawm Exd II BT4 tau piav qhia hauv qab no.
Ex: Explosion-proof mark
d: Daim ntawv pov thawj tawg yog hom flameproof.Muaj hom kev nyab xeeb IA thiab IB;Ntxiv kev nyab xeeb hom E;Roj puv o;Xuab zeb filling pwm Q;Pouring thiab sealing hom m;Hom sib xyaw (piv txwv li, kev sib xyaw ua ke feem ntau yog siv rau lub thawv tawg-pov thawj).
II: Hais txog cov khoom siv hluav taws xob tawg-pov thawj Class II.Hom khoom siv hluav taws xob tawg no yog tsim rau lwm qhov chaw tawg tawg tsuas yog cov mines thee.(Coal mines yog Class I).Kuj tseem muaj cov chav kawm III: cov khoom siv hluav taws xob rau cov huab cua tawg tawg tsuas yog cov mines thee.Chav Kawm IIIA: flammable ya flocs;Chav Kawm IIIB: tsis yog-conductive plua plav;Class IIIC: conductive plua plav.
B: Class IIB gas.Kuj tseem muaj qib IIC thiab IIA.Chav IIC yog qib siab tshaj plaws thiab tuaj yeem siv tau rau ob qho IIA thiab IIB.Qib IIB tuaj yeem siv rau Qib IIA.Tab sis cov qib qis tsis tuaj yeem siv rau qib siab.
T4: Cov pab pawg kub yog T4, thiab qhov siab tshaj plaws saum npoo ntawm cov khoom siv tsawg dua 135 ° C.
