Gas current pulverizer pulverized polyphosphate is an efficient and safe pulverization


  Airflow mill manufacturer introduces that gas flow mills are very common in some non-metal industries, because gas flow grinding can uniformly uniform, its particle size distribution is not only narrow, but also the surface of the particles is also very smooth. And the shape of the particles is also very uniform, and there will be no strange shape.

  Ammonium polyphosphate (APP) is an efficient, low toxic, low-cost inorganic flame retardant, due to high nitrogen, high anti-moisture resistance. Good thermal stability, small specific gravity, excellent dispersion performance, product proximity neutral, can be used alone or in combination with other flame retardants. It can be widely used for fire-resistant flame retardant for coatings, plastics, rubber, fibers, paper, wood and binders, can also be used as a large area of ​​fire extinguishing in forest, coal fields.

  Polyphosphate is usually used after being pulverized, and Airflow pulverizer is superfined to polyphosphate ammonium pulverization is the most commonly used process in the industry.

  Airflow pulverizer is an apparatus that can achieve ultrafine pulverization on the material. The pulverized particle size can reach 1-74 microns, and the gas flow pulverizer is suitable for material characteristics, and continuous production can be achieved during production. material. For ammonium polyphosphate, it is possible to be an equipped device.

  Polyphosphate is an important high-efficiency inorganic flame retardant that has developed abroad in the past 30 years. It is a non-strain polymer with molecular formula (NH4 N + 2PNO3N + 1, the structural formula is N = 5-2000 my country has been developing production since the 1980s, has been in size and low in the situation. There are not many manufacturers of ammonium polyphosphate in China, and the quality of the products produced is different. The aggregation of the APP produced is generally low (n <100), and the yield is also small. With the development of the economy, the demand for flame retardant materials increases,

  Airflow pulverizer The pulverization of polyphosphate is promoted.

  In terms of quality inspection, ALPA powder technology is particularly stricter. It is well known that a manufacturing process of a ultrafine powder is often up to hundreds. As a special equipment, the airflow pulverizer is a defects in any of the production process.Can make a big disaster. Therefore, ALPA powder technology has established seven process stop points in the production process, which is strictly controlled by different engineers, and each other is independent and mutual supervision, and it is timely discovery and solve the problem. Any detail is unqualified, it is unable to enter the proceeding process, which is the quality monitoring of AlPa powder technology to the production process.
