What are the characteristics of Low phosphorus plastic refractory

Low phosphorous plastic refractroy is a refractory plastic made from phosphoric acid and phosphate. It is characterized by better high temperature performance, but higher cost and shorter shelf life. Therefore, this type of binder is often used together with aluminum sulfate solution to exert their respective advantages.

Low phosphorous plastic refractroy is in the form of hard mud paste, and maintains high plasticity for a long time, contains more plastic clay components, and has more water than ramming materials. It has good plasticity before hardening; it has certain strength after hardening. It has good sinterability, certain volume stability and other high temperature properties at high temperature. It can be made into flakes and blocks. Certain binders can also be added during construction. When used, the mixture is compacted or pounded, and after baking, it can form a dense inner lining and structure.
Aluminum Low phosphorous plastic refractroy, the strength change characteristic is that it increases with the increase of heating temperature, and the high temperature strength drops sharply after reaching 1200 °C.
