Aluminum triphosphate dihydrate - Reference Information
| Introduction | aluminum dihydrogen tripolyphosphate, also known as aluminum tripolyphosphate, aluminum polyphosphate, aluminum dihydrogen polyphosphate, white orthorhombic crystal or solid powder, relative density of 2.31, slightly soluble in water and alcohol, non-volatile, difficult to dissolve in acid, placed in the air for a long time partial hydrolysis, soluble in alkali, in strong alkali solution degradable. |
| application field | as an inorganic Fine Chemical, aluminum dihydrogen tripolyphosphate has the advantages of non-toxicity, storage stability and good weather resistance, is a new generation of environmentally friendly anti-rust pigment, can be used with alkyd resin, phenolic resin, epoxy resin, epoxy polyester, acrylic-melamine resin, styrene-acrylic emulsion, silicone resin, polyaniline resin, polyvinyl chloride, chlorinated polyethylene, chlorinated rubber and other mixed materials are used in the coating industry to prepare anti-rust coatings, zinc-rich primers, thick paste coatings, powder coatings, organic titanium anti-corrosion coatings, rust coatings, fire-resistant coatings, heat-resistant coatings, water-based coatings, etc, color can be freely prepared, anti-rust performance is better than red Dan, zinc chrome yellow, zinc phosphate, zinc molybdate and other materials, the use of good results, by the user. In addition, the application of adsorbents, ion exchangers, refractory materials, inorganic molding materials, catalysts and so on has been widely concerned. |
| preparation | alumina and phosphorus pentoxide (orthophosphoric acid or ammonium dihydrogen phosphate) aluminum orthophosphate is formed by stirring and reacting at 100~200 ℃ in an appropriate ratio. Aluminum orthophosphate dehydration polymerization reaction in high temperature furnace, the structure of the product with the polymerization temperature, polymerization time and material environment atmosphere is different. In order to obtain high purity AlH2P3O10 · 2H2O type product, the polymerization conditions are generally controlled as follows: polymerization temperature 250~400 ℃, polymerization time 3~24h. Water vapor should be introduced into the dihydrate in the later stage of polymerization. When the pigment is produced, AlH2P3O10 · 2H2O is modified with a silicon and zinc treatment agent. The treatment agents are typically silicic acid and zinc salts. The treated product was washed with water, dried, pulverized and classified to finally obtain aluminum dihydrogen tripolyphosphate pigment. |
| Use | is a pollution-free white Rust excellent pigment. Widely used in oil pipelines, bridges, railways, ships, vehicles, chemical equipment and construction industry interior and exterior wall coatings. In the refrigerator primer and construction with latex paint and other aspects of good results. Also used as a catalyst, water glass hardener, adsorption deodorant. |
| production method | alumina method. Reaction equation: Al2O3 6H3PO4 → 2AlH2P3O10 7H2O operation method: α-alumina was mixed with phosphoric acid in a molar ratio R = 0.5-0.2. Dehydration was carried out by heating to 100-200 ° C. With micro-heat to form the first product. This product was heated in an electric oven at 300 to 350 ° C. For 3 to 24 hours in an atmosphere having a high water vapor pressure, and polymerization was carried out to produce aluminum dihydrogen tripolyphosphate. Cooling, the preparation of aluminum dihydrogen tripolyphosphate products. |
