username:root_xxhx click:2978次

Aluminum dihydrogen phosphate is also a chemical substance. Aluminum dihydrogen phosphate is mainly used in the electrical industry, high-temperature kilns, heat treatment resistance furnaces, ceramic buildings, electrical insulation, etc. It is mainly used as a binder for refractory materials in high-temperature kilns. The characteristics of aluminum dihydrogen phosphate: After mixing with refractory aggregates, hardeners, etc. at room temperature, it forms high adhesive strength at a constant temperature of 90-110 ° C for 4-24 hours. After drying at 350-500 ° C, it has high bending resistance, compression resistance, and hydration resistance, and does not soften even when immersed or boiled in water. It is also easy to mix and shape, especially suitable for on-site construction. Aluminum dihydrogen phosphate is also resistant to high temperature, vibration, peeling, and high-temperature airflow erosion. And it has good red line absorption capacity and insulation.
