[0001] The utility model relates to the technical field of alumina powder detection, in particular to a sampling device for detecting nano alumina powder. Background Art

[0002] Alumina powder production technology is becoming increasingly sophisticated, now enabling the production of powders smaller than 1 micron. Nano-alumina transparent liquid XZ-LY101 is colorless and transparent. This nano-alumina transparent dispersion utilizes 5-10 nanometer alumina, which is screened through multiple layers of processing. Adding 5% to 10% to aqueous liquids of various acrylic resins, polyurethane resins, epoxy resins, melamine resins, silicone-acrylic emulsions, and other resins can increase the hardness of the resin, reaching a hardness of 6-8H. This completely transparent nano-alumina liquid can be used in any solvent, whether aqueous or oily, and can be used as a coating material for various glass, gemstones, and precision instruments.

[0003] In the prior art, when testing nano-alumina powder, sampling devices are usually used for sampling. However, the existing sampling devices are unable to take out multiple quantitative samples at one time. On the other hand, the sampling devices are usually unable to be disassembled, which makes it inconvenient to clean the inside of the sampling device, easily causing sample residue and easily contaminating the sample source when used next time.

[0004] Therefore, a sampling device for detecting nano-alumina powder is proposed to solve the above problems. Utility Model Content
