Do you really understand the main purpose of active zinc oxide? Follow Xiaobian to understand it!
1. The active zinc oxide has good rolling and dispersion, with small particle size, light and loose structure, nitrogen adsorption specific surface area, etc., when used as a vulcanization active agent, it is evenly distributed in the rubber compound and the contact area of hydrogen sulfide is large, and the opportunity of interfacial reaction is also large. In addition, the product has a catalytic effect of the active species, which results in a high conversion to zinc sulfide. Therefore, as a vulcanization accelerator and a good synthetic rubber reinforcing agent, it is 50-70% of the amount of ordinary zinc oxide.
2. Used as a UV stabilizer in the rubber industry to improve the atmospheric resistance of polyethylene.
3. The zinc resin prepared by reaction with resin acid can be used to produce quick-drying ink with good coloring effect.
The zinc oxide desulfurizer has the characteristics of large specific surface area, high sulfur penetration capacity, high mechanical strength, large accumulation gap and small bed accumulation. It is widely used in the deep desulfurization and purification process of industrial raw materials such as ammonia, methanol and hydrogen production. Under a certain temperature and pressure, the concentration of trace hydrogen sulfide and organic sulfur in the gas can be effectively reduced.
5. Chemical method production, active zinc oxide is produced by chemical method, I .e. wet method, production of direct method or indirect method of equipment is the production of active zinc oxide.
To sum up, this small series introduces the main uses of active zinc oxide. I hope you can know more about it through the above introduction.
