alumina powder

1. Meaning
The production process of alumina powder is becoming increasingly advanced, and it can now produce alumina powder below 1 micron. Nano alumina transparent liquid XZ-LY101 is colorless and transparent in color. The 5-10 nm aluminum oxide is used in the transparent dispersion of nano aluminum oxide. The aluminum oxide is the aluminum oxide selected by the deep processing of nano aluminum oxide layer by layer. It is added to the water-based liquid of various acrylic resin, polyurethane resin, epoxy resin, melamine resin, silicone acrylic lotion and other resins. The addition amount is 5% to 10%, which can improve the hardness of the resin. The hardness can reach 6-8H, completely transparent. The nano aluminum oxide liquid can be any water-based or oily solvent, and can be used as various glass coating materials, gemstones, precision instrument materials, etc.

2. Nature
1.) Nano alumina transparent liquid XZ-LY101 is transparent and has a high content. No sedimentation or stratification.
2) Nano alumina transparent liquid XZ-LY101 can be an aqueous liquid, an oily liquid, and can be an alcohol, ether, or ketone liquid. All are transparent and have good compatibility.
3) Nano alumina transparent liquid XZ-LY101 pH=7.0, but the specific pH value can be adjusted according to customer requirements. Adjusting the pH value has no effect on the liquid.
4) Nano alumina transparent liquid XZ-LY101 has high hardness and good dimensional stability, and can be widely used for reinforcement and toughening of various plastics, rubber, ceramics, refractory materials and other products.
5) Nano alumina transparent liquid XZ-LY101 significantly improves the density, smoothness, thermal fatigue resistance, fracture toughness, creep resistance, and wear resistance of ceramic materials.
6) Nano alumina transparent liquid XZ-LY101 is an excellent far-infrared emission material, which is used as a far-infrared emission and insulation material in chemical fiber products and high-pressure sodium lamps. In addition, alumina has high electrical resistivity and good insulation performance, which can be applied to the main components of YGA laser crystals and integrated circuit substrates.
7) Improve the scratch resistance and durability of UV cured coatings, which are widely used in fields that require high wear resistance, such as plastic flooring nano alumina XZ-L690 appearing in a white fluffy powder state with a crystal form of γ – Al2O3. Particle size is 20nm; specific surface area ≥ 160m ³
