Shenhai Explosion-Proof
Dersa IIB ji bo hawîrdorên ku têkelên teqemenî yên gazên IIB û hewayê çêdibin minasib e.
| Koma gazê / koma germahiyê | T1 | T2 | T3 | T4 | T5 | T6 |
|---|---|---|---|---|---|---|
| IIA | Formaldehyde, toluene, methyl ester, acetylen, propane, acetone, acrylic acid, benzol, stîren, Qarbon monoqsîd, etil acetate, asîta acetîk, klorobenzen, methyl acetate, klorê | Methanol, etanol, ethylbenzene, propanol, propylene, butanol, butyl acetate, amyl acetate, cyclopentane | Pentane, pentanol, hexane, etanol, heptane, oktan, cyclohexanol, terpentîn, nafta, petroleum (benzînê jî tê de), mazot, pentanol tetrachloride | Acetaldehyde, trimethylamine | Ethyl nitrite | |
| IIB | Propylene ester, dimethyl ether | Butadiene, epoxy propane, etilen | Dimethyl ether, acrolein, karbîdê hîdrojenê | |||
| IIC | Hîdrojen, gaza avê | Acetylene | Karbon disulfide | Ethyl nitrate |
Dabeşkirinên teqemenî-delîlan ji bo madenê li astên bingehîn û ji bo kargehan di astên navîn de têne dabeş kirin. Di nav asta navîn de, jêr-tebeqeyên IIA-yê hene, IIB, û IIC, di rêza hilkişînê de ji kapasîteya teqîn-proof: IIA < IIB < IIC. The 'T' category denotes germî komên. 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.
Di dawiyê de, this explosion-proof product is designed as an bi xwe ewle electrical device, intended for use with Class B gases where the surface temperature does not exceed 135°C.
