Shenhai Explosion-Proof
Chav Kawm IIB yog tsim rau ib puag ncig uas muaj kev sib xyaw ua ke ntawm IIB gases thiab huab cua tshwm sim.
| Gas pab pawg / kub pawg | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, tshuaj propane, acetone, acrylic acid, tshuaj benzene, styrene ua, carbon monoxide, ethyl acetate hmoov, acetic acid, tshuaj chlorobenzene, methyl acetate, tshuaj chlorine | Methanol, ethanol, ethylbenzene, propanol, propylene, butanol, butyl acetate hmoov, amyl acetate hmoov, cyclopentane | Pentane, pentanol, hexane, ethanol, heptane, octane ua, cyclohexanol, turpentine, naphtha, roj av (suav nrog roj av), roj roj, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | propylene ester, dimethyl ether | Butadiene, epoxy propane hmoov, ethylene | Dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | Hydrogen, dej gas | Acetylene | Cov pa roj carbon disulfide | Ethyl nitrate |
Cov ntaub ntawv pov thawj tawg tau muab faib ua thawj theem rau cov mining thiab theem nrab rau cov chaw tsim khoom. Nyob rau theem nrab, sub-classifications suav nrog IIA, IIB, thiab IIC, nyob rau hauv ascending kev txiav txim ntawm tawg-pov thawj muaj peev xwm: IIA < IIB < IIC. The 'T' category denotes kub pab pawg. A 'T’ Kev ntsuam xyuas qhia tau hais tias cov cuab yeej tswj tau qhov kub thiab txias hauv qab 135 ° C, nrog T6 yog qib kev nyab xeeb zoo, tawm tswv yim kom qhov kub ntawm qhov chaw tsawg li tsawg tau.
Thaum kawg, cov khoom tawg-pov thawj no yog tsim los ua ib qho intrinsically nyab xeeb khoom siv hluav taws xob, npaj rau siv nrog Class B gases qhov chaw kub tsis tshaj 135 ° C.
