Product description
Parameters
Product Characteristics:
Activated zinc oxide is white or slightly yellow spherical fine powder, with density of 5.47g/cm3 and melting point of 1,800℃. It is insoluble in water and soluble in acid, alkali ammonium chloride and aqua ammonia, generates basic zinc carbonate with carbon dioxide in damp air, and has main characteristic of particle size of 50-100 nanometer, larger specific surface area than indirect method zinc oxide and direct zinc oxide and higher activity and good dispersity in application. Its refractive index is similar to natural rubber, making the color of vulcanizate more clear and transparent.
Application Range:
1. It is featured by good rollability and excellent dispersity and has small particle size, light and loose structure and large nitrogen absorption specific surface area, so when used as vulcanization activator, it is uniformly distributed in sizing material and has large contact area with hydrothion and great interface reaction opportunity. In addition, the product can assist catalysis of active matters to ensure high conversion rate of zinc oxide into zinc sulfide. Therefore, it is 50-70% of common zinc oxide dosage when used as vulcanization accelerator of synthetic rubber and good reinforcing agent.
2. When used as ultraviolet stabilizer in rubber industry, it can greatly improve atmosphere resistance of polyethylene.
3. Zinc resin made by reacting with resin acid can be used for producing quick drying ink and has good effect of coloration.
4. The made zinc oxide desulfurizer is featured by large specific surface area, high penetration sulfur volume, high mechanical strength, large accumulation gap and small bed pressure drop, and widely used for deep desulfurization and purification process of ammonia, methanol, hydrogen production industrial raw material gases and oil. It can effectively reduce the concentration of trace hydrothion and organic sulfur in gas under certain temperature and pressure.
Packaging and Transport:
1. Inner plastic and outer braiding double-layer packaging
2. Standard bag weight: 25kg
3. Package according to customer demands
4. Guard against damp during transport and storage
