Product Description
Soda ash generally refers to sodium carbonate (Na2CO3), molecular weight 105.99. The purity of the chemical is more than 99.5% (mass fraction), also known as soda ash, but the classification belongs to salt, not alkali. Also known as soda or alkali ash in international trade. It is an important organic chemical raw material, mainly used in plate glass, glass products and ceramic glaze production. It is also widely used in domestic washing, acid neutralization and food processing.
Package:
Packaging: polypropylene preparation bag 25kg ,40kg,750kg,1000kg
Storage and transportation: It should be stored in a dry and ventilated warehouse. It should be protected from rain and rain during transportation. It should be lightly loaded and unloaded during loading and unloading to prevent the damage caused by packaging damage and be stacked in acid isolation.
COA
COA is an important document to prove product accountability. It reflects whether the quality of the tested substance meets the specified standards. It is not important for ensuring product quality and improving product competitiveness.
The COA we provide are all the results of the factory's strict inspection, please rest assured for reference;
