Shenhai Ho phatloha-Bopaki
Sehlopha sa IIB se loketse libaka tseo ho tsona ho hlahang motsoako o phatlohang oa likhase tsa IIB le moea.
| Sehlopha sa khase/sehlopha sa mocheso | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylene, propane, acetone, asiti ea acrylic, benzene, styrene, carbon monoxide, ethyl acetate, asiti ea acetic, chlorobenzene, methyl acetate, chlorine | Methanol, ethanol, ethylbenzene, propanol, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, ethanol, heptane, octane, cyclohexanol, turpentine, naphtha, petroleum (ho akarelletsa le peterole), oli ea mafura, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Ester ea propylene, dimethyl ether | Butadiene, epoxy propane, ethylene | Dimethyl ether, acrolein, hydrogen carbide | |||
| IIC | Haedrojene, khase ea metsi | Acetylene | Carbon disulfide | Ethyl nitrate |
Likarolo tse thibelang ho phatloha li arotsoe ka mekhahlelo ea mantlha bakeng sa merafo le maemo a bobeli bakeng sa lifeme. Ka har'a boemo ba bobeli, likarolo tse nyane li kenyelletsa IIA, IIB, le IIC, ka tatellano e nyolohang ea bokhoni ba ho thibela ho phatloha: IIA < IIB < IIC. The 'T' category denotes mocheso lihlopha. A ‘T’ rating implies that the equipment maintains a surface temperature below 135°C, with T6 being the optimal safety level, advocating for as low a surface temperature as possible.
Qetellong, this explosion-proof product is designed as an bolokehileng ka hare ho naha electrical device, intended for use with Class B gases where the surface temperature does not exceed 135°C.
