Qhov txawv ntawm Explosion-Proof Level CT4 thiab BT4

Explosion-Proof Classification

Hom mob	Gas Classification	Cov pa hluav taws xob	Yam tsawg kawg nkaus Ignition Spark Zog
Sub Kuv	Kuv	Methane	0.280mJ
Factories sab nraum lub Mine	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	Hydrogen	0.019mJ

Chav kawm I: Cov khoom siv hluav taws xob tsim los siv rau hauv cov mines hauv av;

Chav II: Cov khoom siv hluav taws xob tsim los siv rau hauv qhov chaw muaj roj tawg, tsis suav cov thee mines thiab underground chaw;

Chav II yog subdivided rau hauv IIA, IIB, thiab IIC. Cov cuab yeej sau npe ua IIB yog qhov tsim nyog rau ib puag ncig uas siv IIA cov cuab yeej siv; Cov cuab yeej IIC tuaj yeem siv rau hauv cov xwm txheej tsim nyog rau ob qho tib si IIA thiab IIB cov cuab yeej.

Kev sib txawv ntawm ExdIICT4 thiab ExdIIBT4

Lawv cater rau ntau pawg ntawm cov pa roj.

Ethylene yog cov roj ib txwm txuam nrog BT4.

Hydrogen thiab acetylene yog cov pa roj rau CT4.

Cov khoom ntsuas CT4 tshaj cov ntsuas BT4 hauv cov lus qhia tshwj xeeb, Raws li CT4 cov khoom siv tuaj yeem siv rau hauv ib puag ncig tsim nyog rau BT4, whereas BT4 cov khoom siv tsis siv rau hauv ib puag ncig tsim nyog rau CT4.
