The chemical name of the zinc dust product is metallic zinc powder. It is a special form of zinc metal with a gray powder appearance. The crystal structure appears in regular spherical, irregular and irregular scaly shapes due to different production processes. Insoluble in water, soluble in acid and alkali, and highly reducing.
Segmentation areas:
1. Special zinc dust for zinc-rich anti-corrosion coatings: The main use of zinc dust products is as a key raw material for zinc-rich anti-corrosion coatings and is widely used in large-scale steel structures that are not suitable for hot-dip and electroplating (such as steel structure buildings, marine engineering facilities , bridges, pipelines) as well as coating of ships, containers, etc.
2. Special zinc dust for mechanical powder galvanizing: used for galvanizing and anti-corrosion of relatively small prefabricated steel components, bolts, screws, nails and other steel products.
3. Special zinc dust for co-infiltration of multi-component alloys: used in outdoor steel components, fasteners, highways, aerospace, guardrails, bridges, plumbing equipment and building hardware, automobiles, engineering machinery and marine chemicals, metallurgy, power generation, etc. to withstand high temperatures , impact resistance, corrosion resistance and other parts of the zinc infiltration anti-corrosion.
4. Special zinc dust for chemical reduction catalysis: used in the production process of chemical products, such as carnitol powder, dye intermediates, plastic additives, insurance powder, lithopone, etc., and plays the role of catalysis, reduction, and production in the production process. Hydrogen ions and other effects.
5. Special zinc dust for metallurgical impurity removal and replacement: used in the metallurgical process of zinc, gold, silver, indium, platinum and other non-ferrous metal products, and plays the role of reduction, replacement, impurity removal and purification in the metallurgical process.
6. Special zinc dust for pharmaceuticals and pesticides: used in the production of pharmaceutical and pesticide intermediates, mainly plays a catalytic role in the synthesis of organic compounds and the generation of hydrogen bonds.
7. Special zinc dust for diamond tools: It is used in the production of diamond tools. Its main function is to strengthen the alloy strength of diamond tools and use the low melting point of zinc powder to reduce the melting point of copper alloy, thereby reducing the sintering temperature of diamond tools; in the use of diamond tools In the production process, the use of zinc powder can partially replace tin powder to reduce the production cost of diamond tools; in the production process of diamond tools, the use of zinc powder can improve the sharpness of diamond tools.
8. Special flake zinc dust for Dacromet coating liquid: The main raw material used in making Dacromet coating liquid. Since flake zinc powder has stronger covering ability, floating ability, shielding ability and metallic luster than spherical zinc dust, Using the Dacromet coating liquid prepared by it, the zinc powder is arranged in a scale shape, and the parallel overlap and contact mode between the sheets is surface contact, which can effectively improve the conductivity between zinc and steel and between zinc particles. The dense coating and extended corrosion route not only reduce the zinc consumption per unit area and coating thickness, but also improve the shielding performance and corrosion resistance of the coating.
9. Special flake zinc dust for zinc-rich coatings: used in the production of zinc-rich anti-corrosion coatings. Since flake zinc powder has stronger covering ability, floating ability, shielding ability and metallic luster than spherical zinc powder, flake zinc dust is used The zinc-rich coating prepared by the product has good suspension and is not easy to precipitate. The coating surface is bright and has a strong metallic texture. It also has better adhesion between the bottom layer and the coating, low porosity and permeability, and has better corrosion resistance. Under the same anti-corrosion effect, the zinc-rich paint prepared using flake zinc powder series products uses less zinc per unit area and is more environmentally friendly than the zinc-rich paint prepared using spherical zinc powder series products.
