Class A foam fire extinguisher

Our company produces Class A foam fire extinguishers, which are new, high-efficiency compressed air foam fire extinguishers. Its main advantages are fast fire control speed, high water efficiency in fire scenes, significant effects in insulation, radiation protection and prevention of reignition. It can greatly reduce the loss of water at the fire scene and can be arbitrarily mixed according to a ratio concentration of 0.1 to 1%.

Our company's A (compressed air) foam fire extinguisher series products are not only suitable for all compressed air foam fire extinguishing systems, but also for ordinary high, medium, and low expansion foam fire extinguishing systems. However, in these systems, the efficiency of water loss is equivalent to that of other fire extinguishers. Therefore, our company recommends: in the absence of other special requirements, the A-class foam fire extinguisher produced by our company should be installed in compressed air foam fire extinguishing systems in order to play the above advantages and obtain both economic and efficient dual effects.

A-class (compressed air) foam fire extinguisher, with full, fine and strong adhesive foam due to the use of our own self-prepared fluorocarbon composite surfactant in the formula. The foam has good durability and stable water drainage time, and the surface tension and interface tension of the draining water are both very low. When extinguishing Class A fire (solid fire), its foam can not only adhere to the surface of the burning object to form a layer of thermal insulation and radiation protection layer, but also the stable and persistent foam will not flow randomly, reducing water losses. The viscous liquid with strong penetration ability of continuous foam drainage can penetrate into the deep dark area of ​​the solid burning material, promote the surface carbonization of the burning material, cut off the burning chain and terminate the combustion reaction. When extinguishing Class B fire (liquid fire), due to the stable and persistent foam and stable water drainage of the product, the foam quickly spreads under the action of the water film. The stable and persistent foam and stable water drainage can not only extinguish the fire quickly, but also effectively prevent the reignition of the burning material. Therefore, this product has the advantages of stable foam and good effect in preventing reignition.
