Chinese Water-Soluble Flammable Liquid Fire Extinguishing Agent — Industrial Formula, Raw Materials & Process Control
In short: Chinese New water-soluble flammable liquid extinguishing agent — Industrial Formula, Raw Materials & Process Control. This entry documents a formula & ratios taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 3127 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
New water-soluble flammable liquid fire extinguishing agentDue to the development of the modern chemical industry, the production of various hydrophilic alcohols and ketones has surged. In particular, the production of methanol, which is known as a pollution-free fuel, has grown faster and its use has become increasingly widespread. Subsequently, accidental fires caused by these hydrophilic flammable liquids have gradually increased, becoming a serious headache for people. General foam fire extinguishing agents and interface-active fire extinguishing agents are more effective against fires caused by non-water-soluble liquids such as gasoline and light oil, but have no satisfactory effect on fires caused by water-soluble liquid alcohols and ketones. This is because when the foam produced by this type of fire extinguishing agent interacts with the burning hydrophilic liquid, the water content of the bubble body is quickly absorbed by the hydrophilic flammable liquid, and the bubble body bursts and no foam membrane can be formed. Although people have developed a foam fire extinguishing agent based on the hydrolysis products of animal and plant proteins and have achieved certain results in application, however, due to its complicated refining procedures, high production costs, short storage time, and special odor when used, production and application are objectively limited. Recently, someone has proposed a method of adding hydrophilic polymer compounds to fluorine-based surfactants to prepare efficient fire extinguishing agents. Good results have been achieved through tests. There are four formulas:1.Fluorine surfactant (hereinafter referred to as foaming agent)6 pointsCarboxymethyl cellulose (hereinafter referred to as C, M, C)2 pointsDiethylene glycol-butyl ether3 points2.Foaming agent6 …
