The chemical composition of aluminum hydroxide is Al2O3, 2H2O or Al (OH) 3, with molecular weight of 78. It is an amphoteric compound with certain activity. It can be dissolved in acid and alkali to form aluminum salt and aluminate. When heated to 200, it begins to decompose, rapidly dehydrate and presents endothermic reaction. Due to this characteristic, it is mainly suitable for the production of inorganic aluminum salt, flame retardant and alumina products.
Application of ATH in FRP
Glass fiber reinforced plastic (FRP) is also called GFRP, that is, fiber reinforced plastic, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics that use glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics, or glass steel. FRP is a composite material that has developed rapidly in the past 50 years. 70% of the output of glass fiber is used to make FRP. According to relevant statistics, there are tens of thousands of types of FRP products developed by countries all over the world. It is widely used in construction, transportation, home furnishing, industrial equipment, electrical appliances, etc.The application of ATH in FRP is not only flame retardant, but also can be used to change rheology and dimensional stability.
