Molecular formula: Zone
Appearance and properties: white hexagonal crystals or powder, odorless; zinc oxide is a compound of gender, through its combination of basic with acidic substances.
Physical properties: Melting point 1975 ℃ Solubility insoluble in water, ethanol, soluble in acid, sodium hydroxide solution, ammonium chloride
Main use: used as a paint pigment and rubber filler. Medicine used for the system ointment, zinc paste, plaster, etc.
Zinc oxide rubber and tire industry also used as an essential additive in natural rubber, synthetic rubber and latex vulcanization active agents and reinforcing agents, and coloring agent.
In the chemical industry, zinc oxide is widely used as a catalyst, desulfurization agents, such as when the synthesis of methanol as a catalyst, when ammonia desulfurization agent; high activity of nano-ZnO surface can increase the choice of catalyst performance and catalyst efficiency, with a wide range of potential applications.
In the paint industry, zinc oxide addition to color strength and hiding power, the preservative is paint and light-emitting agent; In addition, the nano-ZnO excellent UV shielding capacity of its anti-aging, etc. in the coating has more prominent characteristics.
In the medical and health and food industries, zinc oxide has a Sida, bleeding, myogenic function of convergence, but also raw materials used in plaster, but also for the promotion of children's intellectual development with the help; nano-zinc oxide used in food hygiene demands of the industry is gradually expanded, but the product requirements more stringent, in particular the content of harmful heavy metal elements.
In the glass industry, zinc oxide used in the specialty glass products in; in the ceramics industry, zinc oxide used as a flux; in printing and dyeing industry, zinc oxide used to prevent agent; ZnO due to fine particles, active high, you can to reduce the sintering temperature of glass and ceramics, in addition to the use of glazed ceramic nano-ZnO prepared by a more smooth, but also has anti-bacterial, anti-enzymes, deodorant a
