Foam extinguishing agent based on acid solution

Abstract

The invention discloses a foam fire extinguishing agent based on an acidic solution, which consists of 4.6-8.7 parts by mass of a foaming agent, 3.8-7.5 parts by mass of a stabilizer, 27-42 parts by mass of hydrophobic solid particles, and the rest is an aqueous solution mixture, the foaming agent is alum or licorice powder; the stabilizer is polyaluminum chloride, and the hydrophobic solid particles are calcium carbonate particles, sodium bicarbonate dry powder, iron oxide particles, titanium dioxide particles, modified sodium salt Dry powder, potassium salt dry powder, ammonium dihydrogen phosphate dry powder, diamine phosphate dry powder, sodium bicarbonate-like dry powder, iron oxide particles, titanium dioxide particles, modified sodium salt dry powder, potassium salt dry powder, ammonium dihydrogen phosphate dry powder, diamine phosphate dry powder A mixture of one or more of them; the solvent of the aqueous solution is water, and the solute is potassium hydrogen tartrate, 6% dilute hydrochloric acid, sodium acetate trihydrate, sodium carbonate, potassium perchlorate, salicylic acid, dipotassium hydrogen phosphate, sulfuric acid One or more mixtures of potassium. The fire extinguishing agent provided by the present invention can evenly adhere to the oily substance, and the foaming agent can rapidly combine the uncovered area freely to form a covering layer, which isolates the necessary oxygen needed for combustion, and forms combustibles and The physical isolation between oxygen has achieved the effect of fire extinguishing.

Description

technical field [0001] The invention relates to the field of fire-fighting materials, in particular to the field of fire extinguishing agents used for fire extinguishing, in particular to a foam fire extinguishing agent based on acidic solution. Background technique [0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers contain different ingredients and are specially designed for different fire alarms. Care must be taken during use to avoid adverse effects and danger. [0003] The existing fire extinguishing agents mainly include foam and dry powder, both of which have their own advantages and disadvantages. The fire extinguishing agent in the dry powder fire extinguisher is filled with dipotassium hydrogen phosphate salt fo...
