Specifications:

 

1. Liangjiang brand zinc oxide, used in ceramics:

Zinc oxide, also called zinc white, an important raw material of chemical ceramic solutions, in ceramic industy, zinc oxide is widely used in Brick and tile glaze, Coarse pottery translucent glaze and Craft cutlery after transparent glaze thick fritted glaze. Especially the floor tile of wall of pottery and porcelain glaze and the dosage of low temperature ceramic glaze in the building.

2. zinc oxide in glaze:

Zinc oxide in the glaze has the strong help fusion effect, can reduce the expansion coefficient of glaze and improve the thermal stability of the product, at the same time can increase the luster of the glazed with white degree, improve the flexibility of the glaze. In expanding the horizons of melting, at the same time, can increase the luster of the glaze. But in the black glaze of containing chromium, unfavorable use.

 

3. Liangjiang brand zinc oxide direclt process, Used in rubbers, phosphating solutions, coatings, paints, varistors, thin films, thermal conductive materials and other industries. The heavy metal contents of zinc ingot or zinc slag directly affect the heavy metal impurity content of product, the products with low heavy metals, can also be used in animals feed, medicine, health care and other industries.

 

Item No.1  Liangjiang brand zinc oxide, request for  Phosphating solution:

 

The phosphating liquid production for the raw materials is very high.Obviously, more strict for zinc oxide. Reaction with Phosphoric acid and zinc oxide, if the low purity of zinc in zinc oxide or the purity of zinc oxide is not enough. Two situations as follows,

 

No.1  Consumes more raw materials,reaction with Phosphoric acid. It will affect the purity of the products.

 

No.2 The lead purity of zinc oxide, higher or lower, affects the transparency of the phosphating liquid. Because zinc metlas could be soluble in acids solvent during the heating process.Generally, use zinc oxide indirectly process. Besides, mainly supply  Zinc Ions,the main components of phosphating film. zinc phosphate made by reaction with Zinc oxide and phosphoric acid, could be used in metals surface, Anticorrosive, antirust, that’s zinc phosphate coating on metal surface, as antirust pigment.

Description:

 

1. Zinc oxide is mainly used in the following respects:

No.1 as the fluxing agent: Zinc oxide used as flux in the low temperature frit glaze, general usage was 5% ~ 10%, In the low temperature, raw glaze consumption about 5% in normal operations.

 

No.2 as opacifying agent: add zinc oxide in glazes containing high Al2O3, can improve the glaze opacifying sex. Because zinc oxide and Al2O3 can generate zinc spinel ZnO, Al2O3 crystal. In zinc opacified glaze, Al2O3 can enhance the whiteness of glaze and turbidity. SiO2 can improve glaze gloss.

 

No.3 as crystallization agent: in art crystallization glaze glaze, is indispensable in the zinc oxide crystallization agent, cooling, fast on the melt glaze form for larger crystal pattern, very beautiful. In the crystalline glaze, the usage of zno is as high as 20 ~ 30%.

 

No.4 as making cobalt blue glaze: zinc oxide in cobalt blue glaze flux is very important, it can make beautiful sky blue cobalt oxide formation in the glaze.

 

No.5 as a ceramic pigment: due to the strong help melt role of zinc oxide can be used as fluxing agent in the production of ceramic pigment, mineralizer and glaze carrier.

 

2. Zinc oxide useage, pay attention to the following:

No.1 Before use,need to have high temperature calcination, calcination temperature at about 1200 ℃. If not calcine, directly added to raw glaze, it will influence the glaze process performance. You do not need to calcine in join frit material.

 

No.2 zinc oxide in the glaze , if excessive amount , affects glaze gloss.

 

No.3  zinc oxide have poor effects on certain glaze, especially chromium glaze.

Shanghai liang jiang titanium white products co., LTD., research for long time to study that zinc oxide can also has effects in reducing the bibulous rate of floor tile of wall of pottery and porcelain. The professors inside course of study thinks, in the ceramic glaze formula about the fineness of 1000 mesh of zinc oxide powder, due to the small particle size, specific surface increases, the lower the water absorption. Of course the higher mesh, the higher the price of zinc oxide.
