Method for using aluminum dihydrogen phosphate in refractory materials
Aluminium dihydrogen phosphate is a new type of inorganic synthetic material containing both solid and liquid states. The solid is a white powder. The liquid is a colorless, odorless, viscous liquid that is highly soluble in water. Aluminum dihydrogen phosphate has a very wide range of uses in real life,
It has the advantages of high temperature resistance, anti-flaking and anti-vibration, and it can absorb ultraviolet rays very well and has good insulation performance. It has been widely promoted.
(1) Aluminum dihydrogen phosphate can be used as an anticorrosive pigment. The pigment made of aluminum dihydrogen phosphate is generally white, and the anti-corrosion effect is particularly good. Generally, the white anti-corrosive materials used by us are all very toxic metal materials, and the white paint made of dihydrogen phosphate has no The harmless quality of the performance will not cause pollution to our living environment.
(2) Aluminum dihydrogen phosphate can also be used as a kind of hardener. The addition of alkali metal silicate as a hardener imparts water resistance and can be added to inorganic coatings, inorganic binders and refractory materials as a cherry material to produce various heat-resistant, water-resistant and weather-resistant materials.
(3) In addition, aluminum dihydrogen phosphate can also be used as a catalyst, which is generally used for the catalysis of dehydration reactions. For the catalysis of chemical substances, this standard has not yet been reached, and further research is needed.
With the advancement of the times, the application of aluminum dihydrogen phosphate has gradually expanded. From the original electrical industry, high temperature furnace, heat treatment resistance furnace to the following aspects, in order to better apply aluminum dihydrogen phosphate in the industry, we Let's take a look together:
1. For the manufacture of refractory materials, flame retardants, ceramics, glass, electrical appliances, molds, special coatings, etc.;
2. The high temperature furnace is made of masonry or is made of high temperature cementing material with refractory aggregate;
3. Used as furnace wall refractory coating and high temperature resistant jointing material;
4. It can also be used as an intumescent flame retardant coating for fiber, wood, paper, etc.
5. Used as a coating or bonding material with good dielectric properties in electrical production;
6. Adding aluminum dihydrogen phosphate to ceramic production can improve its high temperature compressive strength and flexural strength;
7. Add it to ordinary Portland cement or alumina cement in the construction industry to shorten the setting time and increase the strength of cement products;
8. In the power industry, its electrical insulation properties are used to produce heat-resistant insulation products.
