According to relevant experiments, it is found that the nano-alumina XZ-L 690 is white and fluffy powder, which can better change the hardness of the laser film adhesive. You can first mix the nano-alumina XZ-L 690 with alcohol After that, the mixed liquid is then added to the epoxy resin AB glue, the crystal form is γ-Al 2 O 3.
The particle size is 20 nm; the particle size distribution is uniform, the purity is relatively high, and the dispersion is relatively good. 3. Good dimensional stability, strong surface acidity and relatively good surface alkalinity. It is widely used as a new green chemical material such as catalyst and catalyst carrier.
It can be applied to the reinforcement and toughening of different plastics, rubber, ceramics, refractory materials, etc., and can increase the compactness, smoothness, cold and hot fatigue, fracture toughness, creep resistance and polymer materials of ceramics. The wear resistance of the product is relatively good. Better dispersion, in solvent water; solvent ethanol, propanol, propylene glycol, isopropanol, ethylene glycol monobutyl ether, acetone, methyl ethyl ketone, benzene, xylene, without dispersing agent, stirring Better dispersion and uniformity. In epoxy resin, plastic, etc., it is better to add and use.
Technical indicators: Nano-alumina white powder. Nano-alumina crystal phase γ phase. The average particle size of nano-alumina (nm) 20 ± {{1}}. The content of nano-alumina is more than%. Melting point: 2010 ℃ -20 {{1}} 0 ℃, boiling point: 2980 ℃, relative density (water=1): 3. 97 -4.0 Scope of application: used to make dental cement, porcelain, paint filler, mordant, aluminum metal, etc. Can be added to different water-based resins, oily resins, epoxy resins, acrylic resins, polyurethane resins, plastics, rubbers, the amount of addition is 3%-{{1}}% Good increase the hardness of the material, the hardness can reach 6-8H or even higher. It can also be used in heat conduction, polishing, electroplating, catalyst, etc.
