Indirect Method Zinc Oxide Production and Uses

The indirect method zinc oxide raw materials is a smelting metal zinc ingot or zinc slag. Under the high temperature of 1000°C, zinc is converted to steam in the graphite crucible. Then produce zinc oxide by blowing air oxidation, and after cooling pipe collection was zno particles. The indirect method is founded in 1844 by French scientist leclerc (LeClaire) promotion, therefore is also called the French Method. The indirect method zinc oxide production technology is simple, the cost is strongly influenced by the raw material. Zinc oxide particles of about 0.1-10 microns in diameter, the purity of between 99.5% -99.7%. According to the output calculation, indirect method is one of the main production methods.

Indirect method zinc oxide uses: it can be used for rubber, varistors, paint, phosphating solution, films, thermal materials and other industries. Zinc ingot or the heavy metal content of zinc slag directly affect the heavy metal impurity content of product. Low heavy metal content of the products, can also be used for livestock feed, medicine, health care and other industries.

Magnesium Oxide Used as Acid Acceptor of Fluorine Rubber

Acid acceptor is also called absorbent or acid-binding agent. It is a kind of material that can efficiently neutralize hydrogen fluoride precipitated in the process of fluorine rubber vulcanization. Acid acceptor can also increase the crosslink density of the fluorine rubber, and make cross-linked rubber good thermal stability, so it is also used as activator or heat stabilizer.    

Magnesium oxide and zinc oxide are generally used as acid acceptor. When used zinc oxide, often used with equal number of dibasic lead phosphite for water resistance rubber. However, magnesium oxide is used for rubber which has heat-resisting and no requirements for acid resistance. A mixture of active magnesium oxide and calcium hydroxide is used as acid acceptor in Viton E －60c. Then you can use the rubber of bisphenol AF and BTPPCl to make cross-linked rubber.

Magnesium oxide and zinc oxide have more functions in your production, including acid absorbing agent, curing agent, active agent and others. If you want to know more information about magnesium oxide, or want to solve you production problems, or want to exchange magnesium oxide and zinc oxide suppliers before, you can leave a massage for us or call our telephone number directly.  

The application fields of zinc oxide in rubber products

1.Synthetic rubber

The functions of zinc oxide : in the field of synthetic rubber, zinc oxide plays the roles of active agent, vulcanization agent and reinforcing agent, and making things colorful. What is more, it promotes the vulcanization, activation and reinforcement, prevent aging of rubber, can strengthen the vulcanization process and improve the rubber tearing resistance, abrasion resistance.

2.Natural rubber

The function of zinc oxide : in the field of natural rubber, zinc oxide has the effect on curing activator, which is same as synthetic rubber.

3.Latex

4.White latex

Zinc oxide is used as colorants and filler.

5.Chloroprene rubber

Chloroprene rubber is an beige or light brown bump with particular flame retardant and corrosion resistant. Zinc oxide can be used as curing agents and additives which increases the thermal conductivity.

6.Footwear industry
 
Zinc oxide can be used in the production of rubber shoes, boots, rubber gloves and other labor insurance products. The functions are improving the abrasion resistance and anti aging, prolonging the service life.
7.Transparent rubber and the rubber products used for food
Zinc oxide is the necessary inorganic activator for transparent rubber and the rubber products to be used for food.
8.Transparent and translucent rubber
9.Transparent or colored rubber products
10.Air sealing, gaskets and other products
 
The function of zinc oxide : Having good effect on improving the wear resistance and sealing effect.

Hebei Meishen Chemical Technology Group Co.,Ltd produces amount of zinc oxide which content is about 99.7, the quality is stable and very suitable for export.
