| Description | Aluminum Hydroxide, Al (OH) 3, archaically called hydrate of alumina or alumina trihydrate (Al2O3·3H2O), which is a non-abrasive powder with a Mohs' hardness index of 2.5 - 3.5 and a specific gravity of 2.42. It can be heated to 200°C and hydrated alumina can be decomposed into 66% alumina and 34% water. |
| Function | 1. Micron aluminum hydroxide is added to the fireproof material, and the main stage of improving the fire prevention time of the coating is that in the initial stage of fire prevention, the initial heating rate can be significantly reduced after the addition. 2. The modification of micron aluminum hydroxide with stearic acid shows that the modification can significantly improve the dispersibility in the coating, and the white unprotected layer formed is denser, thereby improving the fireproof performance. 3. When the amount of micron aluminum hydroxide added is 6%, the inorganic flame retardant plays a synergistic role with the organic flame retardant system, the carbonaceous expansion is high, the thermal conductivity is low, and the fireproof time is long. 4.Compared with ordinary aluminum hydroxide, the micron-sized aluminum hydroxide has a large surface area, which can improve the compatibility with the coating, obviously improve the fireproof performance of the coating, and the filling amount is relatively low, and the filling is relatively low. |
