Problems solved by technology

Common fire extinguishing agents include gas, dry powder, water and foam. At present, foam fire extinguishing agents and dry powder fire extinguishing agents are often used for fires in tank farms. Dry powder fire extinguishing agents are dry, easy to flow, good moisture resistance and anti-caking properties However, the existing dry powder fire extinguishing agents have poor cooling performance and re-flammability resistance when fighting large-scale oil pool fires and flowing fires, and the fire extinguishing effect is not good. In addition, when used in three-dimensional combustion type fires, it is not easy to adhere to On the three-dimensional surface of the object, it is easy to fall off, and the fire extinguishing effect is limited

Abstract

The invention discloses a fire extinguishing agent containing modified medical stone powder, which is prepared from the following raw materials in parts by weight: 50-80 parts of modified medical stone powder, 5-10 parts of talcum powder, 10-15 parts of zinc sulfide hydrate, 3-5 parts of calcium carbonate, 5-8 parts of magnesium stearate, 3-5 parts of methyl silicone oil, 2-3 parts of hydrophobic silica white, 3-5 parts of atlapulgite, 2-3 parts of perlite, 2-3 parts of ethylene glycol, 5-8 parts of calcium lignosulphonate, 3-5 parts of bamboo charcoal fiber, 2-3 parts of industrial essence, 2-4 parts of zinc borate, 1-3 parts of chlorinated paraffin, 5-10 parts of glass bead and 8-10 parts of kieselguhr. The fire extinguishing agent has the advantages of high fire extinguishing efficiency, high moisture resistance, favorable after-combustion resistance, environment friendliness and simple production technique, and is suitable for various fire hazards.

Description

[0001] technical field [0002] The invention relates to the technical field of fire protection, in particular to a fire extinguishing agent containing modified medical stone powder. [0003] Background technique [0004] With the implementation of the national energy security strategy and the rapid development of the economy and society, in order to ensure my country's energy security and promote the sustainable development of my country's economy, the super-large oil tank will become an inevitable trend of development, and the potential large-area oil pool The risk of fire and flowing fire fire accidents is also increasing. Once the oil tank fires, the damage will be huge. The use of fire extinguishing agents plays a key role in fire fighting in tank farms. Common fire extinguishing agents are gas, dry powder, water and foam. At present, foam fire extinguishing agents and dry powder fire extinguishing agents are often used for fires in tank farms. Dry powder fire extingui...
