Class D dry powder fire extinguisher LJ-MFZD25 cart type D dry powder fire extinguisher (for sodium-magnesium fires only) This is a kind of liquid fire that can be well aligned and then extinguished. It is very good to carry it by yourself The fire field can be used very efficiently.

Class D dry powder fire extinguisher adopts German secondary decompression technology, which can effectively prevent combustible metal flying and more dangerous dust explosion during fire extinguisher spraying; unique process formula to overcome the easy clogging of Class D fire extinguishing agents of other domestic manufacturers, which needs to be reversed when extinguishing Several shortcomings, fighting for precious fire-fighting time; large-capacity storage pressure to ensure that the remaining spray volume is minimized, and the fire-extinguishing efficiency is the highest. half. Main performance indicators:

When the fire extinguisher is at 20 ± 5 ℃, its performance parameters are as follows.

◆ The calorific value of metal burning is generally 5-20 times that of ordinary burning. The flame temperature is very high during burning. Pay attention to burns when extinguishing fire.

◆ When any metal powder is extinguished by fire, the dust cannot fly up, otherwise a more dangerous powder explosion will be formed.

◆ Frequently check the internal pressure of the fire extinguisher and find that the pointer of the pressure gauge is lower than the green area and should be sent to the manufacturer for repair.
