| titleOfInvention | Method for preparing rare earth element composite high-efficiency superfine powder fire extinguishing agent by spray drying method |
| abstract | A method for preparing rare earth element composite high-efficiency superfine powder fire extinguishing agent by a spray drying method. The method comprises the steps of refining and mixing a rare earth element compound and a powdery fire extinguishing agent base material by a spray drying and crushing method, adding fire extinguishing agent auxiliary materials, and then carrying out surface modification by using emulsified silicone oil to obtain the high-efficiency superfine powdery fire extinguishing agent; meanwhile, in order to solve the problem of hollow structure of the powder particles, the invention adopts the rare earth element compound which has smaller particle size and is insoluble in water, and can form solid composite particles of the powder extinguishing agent base material coated with the rare earth element compound in the spray drying process. The method further improves the fire extinguishing performance of the composite fire extinguishing agent by utilizing the high-efficiency fire extinguishing performance of the rare earth element, and forms solid powder particles of the powder fire extinguishing agent base material coated with the rare earth element compound by utilizing a spray drying and crushing method, so that the particle size of the raw materials can be reduced, the fire extinguishing agent raw materials are mixed more uniformly, and the problem of low bulk density of the powder material prepared by the traditional spray drying method can be solved. |
