Preparing method for foam extinguishing agent based on acidic solution

Abstract

The invention discloses a method for preparing a foam fire extinguishing agent based on an acidic solution, which comprises the steps of putting hydrophobic solid particles into air-drying equipment for sufficient air-drying; putting the hydrophobic solid particles into a ball mill for ball milling; foaming agent, stabilizer, and hydrophobic solid particles are put into a stirrer for mixing and stirring, and the solute is put into clear water and mixed to form an aqueous solution and add the foaming agent, stabilizer, and hydrophobic solid particles in step 3 The mixture is formed into a fire extinguishing agent; the obtained fire extinguishing agent is packed in a pressure-resistant container and stored at 1.8-2.3 atmospheres. In the present invention, by adding the step of ball milling the hydrophobic solid particles, the unit diameter of the hydrophobic solid particles is significantly reduced, and can be more uniformly attached to the surface of the burning object, and the foam produced by the foaming agent can be used in a high-temperature burning environment It can quickly form an insulating film and quickly extinguish the fire.

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 method for preparing foam fire-extinguishing agents based on acidic solutions. 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 hyd...
