Do you know which field is currently used in Zhejiang dry powder medicine?

From another perspective, you may be able to clearly understand what this dry powder medicine is mainly used for. We all know fire extinguishers. Fire fighting equipment mainly used to extinguish fires has always played an important role in our lives. Function, usually we rarely touch it directly, but when a fire occurs, it will always stick to its post, and contribute to the timely fire suppression, or to control the spread of fire.

The fire extinguishing principle of this dry powder fire extinguisher is that the fire extinguisher is filled with ammonium phosphate dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easy-flowing fine powder for fire extinguishing. It consists of inorganic salt with a fire extinguishing effect and a small amount of additives which are dried, crushed and mixed to form a fine solid powder. It is a widely used fire extinguishing agent in fire fighting, and is mainly used in fire extinguishers. Except for the special dry powder chemical fire extinguishing agent for extinguishing metal fires, the dry powder fire extinguishing agents are generally divided into two categories: BC dry powder fire extinguishing agent sodium bicarbonate and ABC dry powder ammonium phosphate. The first is to rely on the volatile decomposition products of the inorganic salts in the dry powder to chemically inhibit and negatively catalyze with the free radicals or active groups generated by the fuel during the combustion process, interrupt the combustion chain reaction and extinguish the fire; The powder falls outside the surface of the combustible material, a chemical reaction occurs, and a glass-like covering layer is formed under the action of high temperature, thereby blocking oxygen and suffocating the fire. In addition, there is a partial dilution of oxygen and cooling effect.

The principle of the use of this dry powder fire extinguisher is to sum up the use of chemical substances to isolate oxygen to achieve the effect of extinguishing fire. We all know that fire requires oxygen to burn. Once the oxygen is isolated, the fire will extinguish naturally.

By mastering this knowledge, we can effectively extinguish the fire and control the fire in time.
