Physicochemical properties
Properties: colorless, tasteless, very viscous liquid or white powder.
Relative density: 1.44 ~ 1.47
Solubility: soluble in water.
Use
It is mainly used in electrical industry, high-temperature kilns, heat treatment resistance furnaces, ceramic buildings, electrical insulation, etc. it is mainly used as the binder of refractory materials of high-temperature kilns.
solid
It is used for fire-resistant spraying coating, fireclay, castable, ramming material and phosphate brick.
Characteristics of solid aluminum dihydrogen phosphate: after mixing with refractory aggregate and hardener at room temperature, it forms high bonding strength at 90-110 ° C for 4-24 hours. After drying at 350-500 ° C, it has high flexural, compressive and hydration resistance, and does not soften even after soaking or boiling in water.
Packaging, storage and transportation
Liquid products are packed in polyethylene plastic drums; Powder products are packed in polypropylene woven bags lined with polyethylene plastic bags. It shall be stored in a ventilated and dry warehouse. It shall be rain proof and moisture-proof during transportation. Handle with care during loading and unloading to prevent impact, inversion and package damage. In case of fire, water, sand and carbon dioxide fire extinguishers can be used.
