Small-Scale Chinese Powder extinguishing agent Production: Workshop Formula, Ratios & Method
In short: Small-Scale Chinese Powder extinguishing agent Production: Workshop Formula, Ratios & Method. 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 1874 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Powder fire extinguisherCurrently, the commonly used fire extinguishing agents in our country are foam fire hydrants and liquid carbon tetrachloride. Although these fire extinguishing agents can prevent fires, they will contaminate the rescued items unsightly, especially books or documents that are difficult to preserve. Powder fire extinguishing agents can avoid the above shortcomings and are more convenient to store and use. The powder fire extinguishing agent used in the present invention is mostly composed of low-boiling point fluorocarbons that are easily vaporized at room temperature and an inorganic porous powder carrier.The low boiling point fluorinated hydrocarbons used in the present invention have the characteristics of flame retardancy, high gas specific gravity and low toxicity. Fluorinated hydrocarbons that can be used include:1.2 MonodifluoroethaneBoiling point 10~ …
