Foam extinguishing agent
Product overview
Foam extinguishing agent is usually made up of foaming agent, foam stabilizer, viscosity reducing agent, antifreeze agent, cosolvent, preservative and water. The utility model is mainly used for extinguishing non water soluble combustible liquid and general solid fire. Special foam extinguishing agent can also be used to put out the fire of flammable liquid.
Classification principle
Foam extinguishing agent can be divided into chemical foam extinguishing agent and air foam fire extinguishing agent.
According to the foam multiple, can be divided into low multiple foam, medium and high foam multiples of three types of foam.
According to the type and use of low expansion air foam extinguishing agent is divided into five types of soluble protein foam, foam, fluoro protein foam AFFF, synthetic foam, anti. Medium and high expansion foam extinguishing agent is a kind of synthetic foam.
Product classification
Chemical foam extinguishing agent (MP)
The commonly used chemical foam fire extinguishing agent, is acidic salt (aluminum sulfate) and alkaline salt (sodium bicarbonate) and a small amount of foaming agent (hydrolyzed vegetable protein or licorice powder) and a small amount of stabilizer (ferric chloride) mixture, the interaction and the formation of foam.
Chemical foam fire extinguishing agent can not be used to fight water and acid bogey chemical and electrical equipment fire. Can also be used as a foam extinguisher internal agent.
Air foam fire extinguishing agent (MPE)
Air foam is a common protein foam solution; it is a certain proportion of foam liquid, water and air after the mechanical interaction of the film bubble group. The relative density of the foam is 0.11-0.16, and the gas in the bubble is air. Foam is hydrolyzed by animal or plant proteins.
Should not be used at high temperatures, is not suitable for fighting alcohol, ketones, ethers and other organic solvents of the fire, the water is not suitable for chemical substances.
Fire resistant foam extinguishing agent (MPK)
An organic acid metal complex salt is added into the protein hydrolysate to form a protein type anti soluble foam solution, and the organic metal complex salt is contacted with water, and the water soluble organic acid metal soap is produced. When the foam is generated, the precipitated organic acid metal soap forms a continuous solid film on the foam layer. The thin film can effectively prevent the water soluble organic solvent to absorb the moisture in the foam, so that the foam can be permanently covered on the liquid level of the solvent, so as to play a role in extinguishing the fire.
Fire can be put out in general liquid hydrocarbons can effectively extinguish the fire of water-soluble organic solvents.
Fluorine protein foam extinguishing agent (MPF)
Ordinary protein foam through the oil layer, because it can not resist the oil pollution, rising to the surface of the oil after the foam itself contains enough fuel to burn, resulting in the destruction of foam. A fluorocarbon surfactant is added into the air foam to produce a protein foam. Fluorocarbon surfactant has good surface activity, high thermal stability, good wettability and mobility.
Used to fight oil fires, can also fight alcohol, ether, ester, ketone, aldehyde and other polar solvents fire. Widely used in large petrochemical enterprises, chemical fiber plant, oil depot, solvent factory, brewery, chemical products warehouse and other places.
AFFF (MPQ)
AFFF is also called "light water" foam extinguishing agent, English abbreviation: AFFF, or fluorine chemical extinguishing agents. Fluoro protein foam extinguishing agent for anti solvent multipurpose foam extinguishing agent, suitable for low expansion foam system, the foam produced in mechanical force, can form a layer of polymer film in fuel and foam at the interface, can effectively protect the foam from the polar liquid damage by the dual role of film and the air foam fire quickly extinguished.
Anti soluble AFFF fire extinguishing oil under high temperature, and is suitable for liquid jet fire. Can save alcohol, esters, ethers, aldehydes, ketones, amines and other water-soluble flammable liquid fire. Widely used in large chemical enterprises, petrochemical enterprises, chemical fiber enterprises, solvent plants and oil fields, oil depots, ships, garage and other places.
Storage requirements
1 product packaging containers for plastic bucket or wall anticorrosion treatment drum.
2 products should be stored in a cool, dry warehouse, to prevent exposure, storage environment temperature of 0 degrees C ~ 45 C.
3 should pay attention to the container clean, can not be mixed with oil or chemical products, so as not to affect the quality of products
