Uses:
Sulfuric acid,one of the most improtant raw chemical materials,is mainly used in fertilizer industry,and it is also widely used in pharmaceutical chemistry,metallurgical industry,rubber chemical fiber,oil sludge,petroleum processing,national defense industry,and etc.
Packing: Bulk
Caution:
Sulfuric acid is a kind of strong acids which is corrosive and dehydrolyzing.To avoid contacting with the skin,the operators must put on their appliances for labor protection.If happended,wash it away with a large amount of clean water or go to hospital as soon as possible.Sulfuric acid is stored,transported,and used strictly in accordance with the safety regulations of fire control and the use of dangerous goods.
Keep it away from organics oxidant and metal powder.Smoking and fire are strickly prohibited when transported with special trunk.
