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

Product Purpose
It is an important chemical basic raw material with a wide range of uses. The chemical industry is used to manufacture formic acid, oxalic acid, borax, phenol, sodium cyanide and soap, synthetic fatty acids, synthetic detergents, etc. In textile printing and dyeing industry, it is used as cotton desizing agent, scouring agent, mercerizing agent, reductive dye and solvent of Haichang blue dye. Smelting industry for the manufacture of aluminum hydroxide, alumina and metal surface treatment agent. Instrument industry used as acid neutralizer, decolorizer, deodorizer. Adhesive industry used as starch gelatinizing agent, neutralizing agent. In addition, it is widely used in enamel, medicine, cosmetics, tanning, coating, pesticide, glass and other industries.
I. Refined petroleum
Petroleum products after sulfuric acid washing, but also contain some acidic substances must be washed with sodium hydroxide solution, and then washed by water, in order to obtain refined products.
Second, printing and dyeing
3. Textile fiber
Four, paper making
5. Improve the soil with lime.
Chemical and chemical reagents.
1, pharmaceutical stomach medicine: the ingredients are aluminum hydroxide, magnesium hydroxide, sodium bicarbonate and a small amount of sodium hydroxide, the main role is to neutralize gastric acid. Sodium carboxymethyl cellulose (CMC) : food, drug emulsification, bonding, film formation. As an anti-fouling redeposition agent in detergents. Alkali cellulose was prepared by reacting refined cotton with NaOH and then etherified with chloroacetic acid in one step.
2, green water treatment agent sodium ferrate (Na2FeO4) preparation 3NaClO(sodium hypochlorite)+2Fe(OH)3(iron hydroxide)+4NaOH==2Na2FeO4+3NaCl+5H2O basic aluminum chloride (PAC/BAC) denaturation of the virus protein. And water purification, wastewater treatment, strong sodium oxide to adjust ph value.
3, ion exchange resin anion exchange resin failure after the general use of 5%-8% NaOH solution regeneration
4, alkaline cleaning agent NaOH solution can be used for a variety of cleaning agents, such as car washing liquid, bottle washing agent, detergent, rust removal agent, disinfectant configuration, mainly used for wine industry bottle cleaning, ceramic metal industry surface treatment and so on
5. Sodium hypochlorite bleach
Seven, rubber, leather
1. Precipitate white carbon black
2, old rubber recovery Old rubber recovery with sodium hydroxide solution for rubber powder pretreatment, and then for subsequent processing.
3. Leather
Metallurgy and electroplating
Ix. The role of other aspects
1. The role of ceramic caustic soda in ceramic manufacturing has two points. First, caustic soda is used as diluent in the firing process of ceramics. Second, the surface of fired ceramic will have scratches or very rough, after cleaning with caustic soda solution, make the surface of ceramic more smooth.
2. Instrument industry used as acid neutralizer, decolorizer, deodorizer.
Packing Specification
1500kg*16IBC
24ton/FCL
Protective Measures
Liquid alkali is shipped by tank truck or tank
Caustic soda is highly corrosive. When it is touched by the skin, it should be rinsed with water immediately. When it splashes into the eyes, it should be rinsed with water or normal saline immediately for 15 minutes.
