1、 Overview
Molecular formula: NaOH, molecular weight: 40.00, commonly known as caustic soda and caustics.
Properties: solid products are granular, highly hygroscopic, easily soluble in water, and strongly exothermic white solids when dissolved; We can also provide different concentrations of aqueous solution products according to customer requirements. The aqueous solution is greasy, alkaline and highly corrosive. It has great corrosive force on skin, fabric and paper. It is easy to absorb carbon dioxide from the air and gradually turn into sodium carbonate. It belongs to inorganic alkaline corrosive goods, and the UN number is un1823.
IIPurpose:
It is mainly used for laboratory chemical analysis, as well as fine chemical manufacturing and other industrial production with high quality requirements.
IIIProduct quality:
The main indicators comply with the standard GB / t629-1997, as shown in the table below:
project | index |
appearance | White uniform particles |
Content (NaOH)% | ≥99.0 |
Sodium carbonate (Na2CO3)% ≤ | one |
Chloride (CL)% ≤ | zero point zero zero two |
Sulfate (SO4)% ≤ | zero point zero zero two |
Total nitrogen (n)% ≤ | zero point zero zero two |
Calcium (CA)% ≤ | zero point zero zero two |
Iron (FE)% ≤ | zero point zero zero two |
Heavy metal (PB)% ≤ | zero point zero zero three |
IVpacking/Storage:
The solid is packed in 25kg thick film polyethylene plastic coated bags; The product shall be stored in a cool, ventilated and dry place and shall not coexist with acidic substances.
