Application :
1. Construction of sulfate corrosion resistance and high temperature proof.
2. Used in rush repairs, leakage stopping , resistance to sulfate attack.
3. CA50-600 refractory cement can use as binder for refractories such as refractory concrete, refractory castable, ramming mixing, gunning mixing and manmade marble bricks.
4. Used as ceramic adhesive.
5. Used for sealing coating products and refractory mortar.
6. Used in chemical industry, metallurgical industry, building materials.
Detailed Product Description:
Pure calcium aluminate cement is produced by fusing selected raw material in Special furnace. After cooling, the clinker is ground using ball mills.
The raw materials of calcium aluminate cement CA-70 are high purity calcium materials and high pure alumina. The raw materials should be mixed according to suitable ratio. The raw material should be burned to partly fuse. After cooling, α-Al2O3 powder added into clinker, then ground to cement. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.
Features
1. High refractoriness
2. Stable chemical properties, good chemical corrosion performance
3. Ideal plasticity
4. Low shrinking
5. High compression strength, good structural integrity
