High Alumina Phosphate Mortar Powdery Refractory
The Description:
Phosphate high alumina fire mortar is a kind of high temperature refractory material, mainly composed of high alumina, phosphate and other auxiliary materials. It has excellent fire resistance, can be used at high temperatures for a long time, is the ideal material for a variety of high temperature industrial equipment.
The main component of phosphate high alumina fire mortar is high alumina, which is a natural mineral with aluminum content of more than 50% and has very high fire resistance. Phosphate is a kind of chemical substance that can react with high alumina to produce aluminum phosphate, which can enhance the fire resistance of high alumina and improve the service life of phosphate high alumina fire mortar.
The production process of phosphate high alumina fire mud is relatively complicated and needs to go through many processes. The high alumina stone is first broken into powder and then mixed evenly with phosphate and other auxiliary materials. Then the mixed material is mixed with water to form a mud, and then through forming, drying, sintering and other processes, the final phosphate high-aluminum fire mortar is made.
