1. Liangjiang brand zinc oxide directly process, takes zinc ingots No.0 as the raw materials, Under the condition of certain oxidation, made into zinc oxide by zinc vapor burn. This process mainly produces zinc oxide 99.7% - 99.5%. Appearance is white powder, stable under normal temperature, it has good covering power and tinting strength. Insoluble in water and alcohol, soluble in acid, alkali ammonia salt solution, both sexes oxide. To absorb carbon dioxide in the air and water generated with a white zinc carbonate. Heat the time-varying huang, recover white after cooling.
2. Liangjiang brand zinc oxide indirectly process, Founded in 1844 by French scientist leclerc (LeClaire), therefore also called the French process or methods. Zinc oxide indirectly process ,production technology is simple, the cost is strongly influenced by the raw material. Zinc oxide indirectly process, the particles diameter from 0.1micros to 10 microns , purity between 99.5% and 99.7%. According to the output calculation, indirect method is one of the main production processes of zinc oxide. Zinc oxide indirectly process can be used in rubbers, varistors, paints and other industries. The heavy metal content of zinc ingot or zinc slag directly affects the heavy metal impurity content of product, low heavy metal content of products, can also be used for animals feed, medicine, health care and other industries.

3. Liangjiang brand zinc oxide, used in rubber products.
Zinc oxide is a surfactant of natural latex.Sometimes used as a reinforcing agent and colouring agent.According to the different production methods, it can be divided into zinc oxide indirectly, zinc oxide directly and zinc oxide activated.It is the most important inorganic active agent in rubber industry .to be joined into the rubbers, can not only speed up the curing, also can improve the degree of crosslinking.Activation for thiazole sulfonamide, times, guanidine, thiuram promoters.Widely used in all kinds of rubber products, especially for the products of transparent rubber and contact with food. Zinc oxide Industrial production, 50% flow to the rubber industry. Zinc oxide and stearic acid as an important reactant, one of the raw material in rubbers.A mixture of zinc oxide and stearic acid strengthened the hardenability of rubber.Zinc oxide is also an important additive of car tyres.In addition to the sulfuration, zinc oxide can greatly improve the heat transfer performance of rubber, which can help the heat dissipation of the tires, ensure to the driving safety.Zinc oxide additives as well as to prevent the erosion of rubber from mold creatures or ultraviolet rays.
No. 1 Senior black and dark rubber tyres, radial tyres.
Function: Improve the product's thermal conductivity, wear resistance, tear resistance, tensile strength and other indicators, and can save about 30% usage of zinc oxide.
No.3 Liangjiang brand zinc oxide, used in synthetic rubbers:
Function: as activator, vulcanization agent and reinforcing agent, and the shading effect. Promote rubber vulcanization, activation and reinforcement, prevent aging, can strengthen the vulcanization process, improve the rubber tearing resistance, abrasion resistance.
No.4 Liangjiang brand zinc oxide, used in natural rubbers:
Function: as vulcanization activator, the promotion of rubber vulcanization, activation and reinforcing, prevent ageing effect, can strengthen the vulcanization process, improve the rubber tearing resistance, wear resistance
Function: as activator, the promotion of rubber vulcanization, activation and reinforcing, prevent ageing effect, can strengthen the vulcanization process, improve the rubber tearing resistance, wear resistance.
