Target Visitors: Ceramics manufacturers, PAC manufacturers, Refractory manufacturers,
1. Calcined Alumina
Using quality raw materials and processed with rotary kiln in appropriate temperature, the production has a good conversion rate and stable phase with low impurities. Commodities made by the production has advantages of high mechanical strength, stable shrinkage rate, great electrical insulation property, high wear and corrosion resistance in high temperature.
Application:
Grinding material & tools；Wear resistant filler
Raw material of alumina fine powder for porcelain and fire retardant.
High alumina porcelain & high purity structural ceramics
2.Tabular Alumina
Taking high quality aluminum hydroxide as raw material, tabular alumina has been processed with high temperature flash calcination technique with high whiteness and lower containment of Na2O, heavy metal and other impurities. It also has stable chemical properties for its α phase and BET are both controllable. Besides, it has less apparent porosity and water absorption rate but with high closed porosity ratio. With all these advantages, tabular alumina can highly improve the thermal stability, slag resistance and abrasive resistance of refractory material, thus increase its service life.
Application:
Refractory brick made of magnesium aluminum carbon and magnesia spinel
Refractory material used in iron, casting and porcelain industries
3. High Whiteness Aluminium Hydroxide for Fillers
This product has less impurities, perfect crystallization, low oil absorption, high strength, good transparency and high whiteness, and enjoys the reputation of “Chinese White”. With low processing viscosity, stable chroma and flame retardant properties, it is a high quality material of middle and high end artificial marble, artificial crafts and so on. The solid surface produced with this product as filler has jade visual sensation, good transparency, excellent pollution resistance, and can realize the special-shaped processing.
4.Fine Aluminum Hydroxide
Chalco’s super fine Aluminum Hydroxide is generated from high purity sodium aluminate solution by precipitation process, with small particle size, good crystal shape, high whiteness, high chemical purity, narrow particle size distribution, low conductivity characteristics. As an environment friendly flame retardant filler, it is widely used in low-smoke halogen-free cable, silicone rubber, lithium battery diaphragm, foam insulation materials, paper making filler, thermoplastic PVC and so on.
