Caustic Soda CAS 1310-73-2 Liquid Naoh 30% 32% 50% Min Purity Sodium Hydroxide Lye

1. 1. Description

Lye is a kind of sodium hydroxide, that is, liquid sodium hydroxide, also known as sodium hydroxide solution, generally pure liquid caustic soda is called liquid alkali, colorless transparent liquid.

Pure lye is a colorless transparent liquid. The relative density is 1.328-1.349, the melting point is 318.4℃, and the boiling point is 1390℃. Pure liquid caustic soda is called liquid soda and is a colorless transparent liquid. Industrial products contain more impurities, mainly sodium chloride and sodium carbonate, and sometimes a small amount of iron oxide. When dissolved into a concentrated liquid base, most of the impurities will float on the liquid surface and can be separated and removed.

1. 4. Application

It is an important chemical basic raw material and has a wide range of uses. Chemical industry for the manufacture of formic acid, oxalic acid, borax, phenol, sodium cyanide and soap, synthetic fatty acids, synthetic detergent and so on. Textile printing and dyeing industry used as cotton desizing agent, boiling agent, mercerizing agent and reduction dye, Haichang blue dye solvent. Manufacturing aluminum hydroxide, aluminum oxide and metal surface treatment agent for smelting industry. The instrument is used in industry as acid neutralizer, decolorizing agent and deodorizing agent. Adhesive industry used as starch gelatinizer, neutralizer. In addition, it is widely used in enamel, medicine, cosmetics, leather, paint, pesticide, glass and other industries.

① Refined petroleum

After the petroleum products are washed with sulfuric acid, some acidic substances must be washed with sodium hydroxide solution and then washed to obtain refined products.

② Printing and Dyeing

③ textile fibers

④ Paper Making

⑤ Improving the soil with lime.

⑥ Chemicals and chemical reagents.

⑦ rubber, leather

⑧ Metallurgy, electroplating

⑨ The role of other aspects

The role of ceramic caustic soda in ceramic manufacturing has two points, first, in the firing process of ceramics, caustic soda as a diluent. Second, the surface of the fired ceramic will be scratched or very rough, and after cleaning with caustic soda solution, the ceramic surface will be smoother.

The instrument is used in the industry as an acid neutralizer, decolorizing agent and deodorizing agent.
