Introduction:
Caustic soda flake is a basic chemical raw material widely used in papermaking, synthetic detergent, soap, viscose, rayon, cotton fabric and other light textile industry fields, pesticide, dye, rubber and chemical industry fields, petroleum drilling, petroleum refining, tar oil refining, national defense industry, industrial machinery, timber processing, metallurgical industry, pharmaceutical industry and urban construction, etc.

Sodium hydroxide (NaOH)
Commonly known as caustic soda, white crystal at room temperature with strong corrosiveness. Easily soluble in water and its solution is strongly alkaline to make phenolphthalein red. Sodium hydroxide is a very common alkali and is one of the chemical lab essential drugs. It is easy to absorb water vapor in the air, so it must be kept under seal and use rubber stopper. Its solution can be used as washing liquid.
