Sodium hydroxide  

 

Industrial liquid Sodium hydroxide 
Molecular formula: NaOH 
Relative Molecular mass: 40 
Performance: My company has diaphragm, ion exchange membrane two production lines of the product is strongly alkaline. 
Main Uses: is a basic chemical raw material, widely used in papermaking, textile, light industry, metallurgy, petroleum, chemical industry in particular, because of its high purity caustic soda containing sodium chloride, iron and other impurities minimal, except. for these industries, more suitable for chemical fiber, rayon and other industries. 
Packaging: Industrial liquid Sodium hydroxide shipment by tankers, tank tank before use to ensure clean. 
Transportation and Storage: The product should be stored in dry warehouse to avoid breakage, contamination, moisture and contact with the acid, to prevent collision during transport. 
Safety: Because this product is highly corrosive, must wear protective goggles and rubber gloves and other labor protection appliance operation.
