Note: We can supply different size products of AlOOH nanopowder according to client's requirements.
With boehmite crystal form, it is mainly used as a key ink-absorbing material for high-end digital inkjet printing media. In addition to its basic function as an ink-absorbing material, the nano-alumina powder is also easy to disperse in use. The color ink-jet printing photographic paper produced by the nano-alumina powder has the characteristics of waterproof, fast ink absorption, high gloss, and bright colors.
Application of AlOOH nanopowder:
Advantage 1: The current is too large to block the current. The lithium battery separator of the PP/PE material is a through hole. When the current is too large, the perforation phenomenon is likely to occur, thereby causing the lithium battery to burn or explode. The high purity alumina or boehmite (ALOOH) is used as the coating material. The use of adhesives coated on the surface of PP/PE material can play a role in hole adjustment, because high-purity aluminum oxide and boehmite (ALOOH) have a plate-like crystal structure. When the current is too large, the material will generate heat. The plate-like crystal structure of the high-purity alumina or boehmite (ALOOH) coating material will expand in volume and close the current conducting hole in the separator of the lithium battery so as to block the current when the temperature is lowered. When the material volume shrinks, the current conducting hole in the diaphragm will be reopened. Using the special physical and chemical properties of the material, the safety performance of the lithium battery can be greatly improved, thereby providing high energy safety for the high-power lithium battery. Safe and reliable charging and discharging provide the possibility.
Advantage 2: High-purity alumina or boehmite (ALOOH) material also has very good thermal conductivity. The battery temperature is too high. This material can conduct heat conduction well, thus solving the poor thermal conductivity of PP/PE materials. problem.
Advantage III: High-purity alumina or boehmite (ALOOH) material also has excellent flame retardancy, because high-purity alumina or boehmite (ALOOH) material itself is a very good flame retardant, even because of the temperature Excessively high, reaching the zero point of combustion, the good flame-retardant properties of the material will prevent a wide range of burning and even explosion.

Storage conditions:
AlOOH nanopowder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
