Sodium Sulfate Anhydrous Uses
Sodium Sulfate Anhydrous is an important raw material for light industry and chemical industry. It is widely used in chemical, light industry, textile,building materials, pharmaceuticals, fertilizers, synthetic fibers and more than 20 industries.
- In the chemical industry, it is used as a sodium sulfide, sodium silicate water glass and other chemical products.
- In the papermaking industry, it is used to make the cooking agent when manufacturing sulfate pulp.
- In the glass industry, it is used to replace sodium carbonate as a solvent.
- In the textile industry, it is used to deploy Vinon spinning coagulants.
- It can be used for non -ferrous metal metallurgy, leather, etc.
- It is mainly used as a filling material for synthetic detergents.
- It makes calcium aluminum aquamic acid generated faster, which accelerates the hydration and hardening speed of cement.
- It can be used as a buffer in a galvanized sulfate to stabilize the pH value of the plating fluid
The Difference Between Mineral Process and By-product Process
Mineral Sodium Sulfate Anhydrous, its main raw material is mirability ore, the process is by dissolving it by watering the ground, the obtained saturated solution is extracted to the ground, and then steam evaporation crystallization, to get the final products.
By-product Sodium Sulfate Anhydrous, in industrial production, there are many waste liquid containing sodium sulfate such as chemical fiber, oxalic acid, formic acid, pesticides, white carbon black and other industries, and these waste liquid all need to be dealt with. Using the method of evaporation crystallization, sodium sulfate anhydrous can be crystallized from sodium sulfate waste liquid, and then centrifuge, evaporation to get final products.
