Product Description
Caustic soda flakes, also known as solid sodium hydroxide, are white, translucent flakes that dissolve readily in water with the release of significant heat. This product is highly corrosive and must be kept away from direct contact with skin and eyes.
Industrially, caustic soda flakes serve as a vital chemical feedstock, extensively used in papermaking, synthetic detergent production, textile printing and dyeing, and water treatment. Additionally, food-grade products compliant with national standards exist, functioning as acidity regulators and processing aids within the food industry.
Package
Flake: 25kg net PP/PE, kraft paper compounded bag
Solid: 200kg, 400kg net iron drums
or as clients' request.
Application
1. Chemical Manufacturing: Serves as a base material for producing various sodium salts, detergents, and organic chemical products.
2.Petroleum Refining: Used to remove acidic impurities and sulfides from petroleum products.
3.Paper Industry: Employed as a cooking and neutralizing agent during pulp processing.
4.Textile Printing and Dyeing: Serves as a mercerizing agent for cotton fabrics and a dyeing auxiliary.
5.Water Treatment: Functions as a neutralizing agent and cleaning agent for pH adjustment and equipment cleaning.
6.Food Industry: Acts as a processing aid (acidity regulator) in specific food manufacturing processes.
7.Metallurgy and Electroplating: Employed for degreasing and cleaning metal surfaces, as well as in bauxite smelting.
