Introduction Name: Magnesium sulphate anhydrous CAS No: 7487-88-9 Foemula:MgSO4 Apperance:Granular or Powder Application Magnesium sulphate anhydrous has proven to be beneficial in the production of pulp.As stabilizers it prevents browning.The product has also shown its effectiveness in the subsequent refinement procedure,so-called alkaline bleaching. Magnesium Sulphate is used to increase the selectivity of oxygen bleaching delignification,improve the quality of cellulose,and save the amount of chemicals used. Magnesium salts play a role in protecting cellulose during oxygen bleaching of pulp,because they can passivate the metal ions contained in the pulp that can act as catalysts,but in small amounts. In addition, construction chemical MgSO4 sulfuric acid magnesium salt can be used in fireproofing, textile processes, ceramics, cosmetics, and fertilizers.
