The project is aimed at the problems of high oil absorption rate, low dehydration temperature and large particles and black spots in the aluminum hydroxide products. Guilin Hengda Mining Machinery Co., Ltd has carried out research on its particle size distribution, insulation performance and thermal stability etc, and optimized the production process to form a series of products. The equipment made of micronized aluminum hydroxide has the following characteristics and innovations:
(1) Using the Raymond mill technology to remove coarse particles in the fine powder aluminum hydroxide, improving the particle size distribution of the product, and meeting the requirements of the electronic material for the fine powder aluminum hydroxide;
(2) Developed iron removal technology with independent intellectual property rights to improve the insulation performance of products;
(3) Optimize the process parameters so that the dehydration temperature of the flame retardant aluminum hydroxide (filter cake and micro powder) is increased from 195℃to 205℃～210℃;
(4) Through the research on synthesis process and deep processing technology, three varieties of H-WF-1, H-WF-2 and H-WF-3 and their modified products were formed, and the quality reached the advanced level of similar foreign products.
Experts believe that the products produced by this process have the characteristics of high purity, good thermal stability, reasonable particle size distribution, low specific surface area, low oil absorption rate and low electrical conductivity. The production process is easy to control, the cost is low, and the overall technology has reached the international advanced level. The preferred equipment for the processing of micro-powder of aluminum hydroxide, Guilin Hengda Mining Machinery Co., Ltd. is highly recommended. Our company is engaged in the production and sales of grinding equipment such as Raymond grinding mill, ultra-fine grinding mill and micro powder grinding mill etc. Welcome to buy equipment from our company.
