Why bta coating Cu?
Bta coating nanotechnology is a relatively stable coating technology on the surface of metal particles, so that the metal nanoparticles can not be affected by the environment, and the shell can improve the surface electrical properties and surface activity of the core particles, and effectively prevent the agglomeration of metal nanoparticles.
Bta coated copper nanoparticles are relatively stable at room temperature, and the BTA layer can better protect the coated copper nanoparticles. Bta coated copper nanoparticle protection technology has greatly expanded the application range of copper nanoparticle, which has huge potential application value in chemistry, materials, physics and many other fields.
Applications
1. Wear-resistant repair materials
Ultra-fine copper nanoparticles are very easy to combine with various metal materials such as iron and aluminum to form alloy materials. As a wear-resistant repair material, it can first fill the 0.508-25.4um roughness of modern machine tool processing metal surface and the processing deviation of about 5 microns This is what the modern machinery processing industry cannot achieve, which is required for precision wear-resistant instruments and equipment.
2. Conductive
In the electronics industry, ultra-fine copper powder is the best conductive composite material, electrode material, the terminal and internal electrodes of multilayer ceramic capacitors, and electronic packaging pastes for electronic components. Compared with ordinary copper powder, it will bring quality and performance. Great changes.
3. Catalyst
In the petrochemical industry, ultrafine copper and its alloy powders are used as catalysts with high efficiency and strong selectivity. They can be used as synthesis catalysts in the process of carbon dioxide and hydrogen synthesis of methanol, acetylene polymerization, and acrylonitrile hydration.
4. Wear-resistant materials
In the mechanical brake industry, copper powder is an excellent wear-resistant material. It can be used with various non-metallic materials to produce extremely high-quality friction parts, such as brake bands, clutch discs, etc.
5. Functional coatings and sterilization sanitary coatings.
6. Electromagnetic shielding
Solve the electromagnetic shielding and conductive problems of ABS, PPO, PS and other engineering plastics and wood. The production of electromagnetic shielding engineering materials has the advantages of low cost, easy coating, good electromagnetic shielding effect, and wide application range. It is especially suitable for engineering plastics. The electronic products of the housing are resistant to electromagnetic wave interference.
Storage
Copper nanoparticles(20nm bta coated Cu) should be sealed in vacuum bags.
Stored in cool and dry room.
Do not be exposure to air.
Keep away from high temperature, sun and stress.
