Problems solved by technology

[0004] The traditional phosphate combined with refractory and wear-resistant plastics has the following problems: using expensive refractory raw materials such as corundum and silicon carbide as the main material, the cost is relatively high
Phosphoric acid or phosphate is an acidic substance with strong corrosiveness, which poses a great safety hazard during production and use
[0005] The existence of the above problems limits the use of phosphate combined with refractory and wear-resistant plastics, especially in environments with low operating temperatures.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant materials, and in particular relates to composite bonded fire-resistant and wear-resistant plastics with an operating temperature of 300-1100°C. Background technique [0002] Most modern industries cannot do without high temperature, such as steel, cement, glass, thermal power generation, petrochemical industry, etc. Many high-temperature industries are accompanied by the wear of high-speed media. Such as: the flue gas of the pellet sintering machine in the iron and steel industry contains abrasive media; the dust removal device in the cement industry; the boiler for thermal power generation, especially the cyclone separator of the circulating fluidized bed boiler withstands the dual effects of high temperature and high-speed coal ash; Chemical refinery equipment cyclone separator, etc. The above devices all use refractory and wear-resistant castables or plastics. Refractory wear-resista...
