Aluminum dihydrogen phosphate

powder aluminium dihydrogen phosphate:
Aluminium dihydrogen phosphate is a colorless, odorless, extremely viscous liquid or white powder that is readily soluble in water. Used as a binder for refractory materials, mainly used in the electrical industry, high temperature furnaces, heat treatment resistance furnaces and electrical insulation. Also used in petroleum, chemical, shipbuilding and space technology. It can also be used as an inorganic coating in combination with an organic coating. Colorless, odorless and viscous liquid or white powder, soluble in water. Curing at room temperature, strong combination of liquid and curing, high temperature resistance, vibration resistance, peeling resistance, high temperature airflow erosion. And has a good red line absorption capacity and insulation.

At present, the highest temperature resistance of organic adhesives on the market usually does not exceed 1000 °C. The current high temperature resistant inorganic adhesive uses a proprietary high temperature solution that can withstand temperatures above 3000 ° C and can be used in fire for extended periods of time without deformation.
The use of refractory spray coating, fire mud, castables and bonding agents for the foundry industry is mainly used in the production of corundum, chrome corundum nozzles for refractory industry and chrome aluminum zirconium corundum bricks for coal water slurry gasifiers. Liquid solid aluminum dihydrogen phosphate features: easy to mix, forming, especially suitable for on-site construction.
It has broken the worldwide technical problem that solid-resistant aluminum dihydrogen phosphate has a temperature resistance below 1000 °C. The high temperature resistant inorganic binder is composed of an inorganic base and a metal oxide, a hydroxide or the like. High temperature resistant rubber has excellent high temperature resistance, small shrinkage, high hardness, high wear resistance and good aging resistance. It is a kind of special adhesive with promising future. Solid aluminum dihydrogen phosphate is a gray or slightly yellow viscous liquid, soluble in water, weakly acidic, free of sodium ions, suitable for bonding at temperatures between 300 ° C and 1800 ° C, especially suitable for high temperature furnaces Masonry or repair. Such as ceramic bonding, various high-temperature furnaces, heat treatment furnace masonry and repair, kiln wheel repair spray materials, and paste aluminum silicate refractory fiber.

powder aluminium dihydrogen phosphate use
(1) Advanced materials rare earth oxides are used in the new binders. The refractory material can be caused to sinter at a temperature of 900 ° C to 1100 ° C. (1) A high-grade material rare earth oxide is used in the novel binder. It can promote the refractory material to be sintered at a temperature of 900 ° C - 1100 ° C, so that the compressive strength of the refractory material can reach higher data, enhance the wear resistance of the refractory material, and make the product resistant to the erosion of high concentration dust and reduce wear. Therefore, it is very suitable for use in circulating fluidized bed boilers.
(2) Super strong bonding of high temperature resistant materials, Zhisheng Weihua high temperature resistant inorganic binder and bonded materials such as corundum, quartz, high alumina ceramics, graphite, carbon and carbide, high temperature metal refractories have good Wettability and gluing properties. It also has good strength at high temperatures, the average compressive strength at 1300 ° C is 90 MPa (MPa), and the tensile strength is 8 MPa (MPa). The binder has a thermal expansion coefficient equivalent to that of the base refractory material, which improves the performance of the high temperature resistant material and prolongs the service life.
(3) The high temperature resistant inorganic binder adopts phosphate colloid to make the product have strong bonding ability and plasticity, and has temperature operation. It can be applied to coatings that need to be coated on metal, graphite, and various types of high temperature resistant materials to form a protective layer. For example: high temperature oxidation protection coating for metal materials, flame retardant coating, high temperature oxidation protection coating for graphite materials. It can also be used in high temperature furnace lining materials, such as integral construction materials and repair materials, masonry materials, joint materials and other amorphous refractories.
