Liquid alkali has a wide range of applications and my country has become the world’s largest producer

Liquid caustic soda is a type of sodium hydroxide, which refers to pure liquid caustic soda. Its molecular formula is NaOH and its appearance is a colorless and transparent liquid. Liquid caustic soda is an important chemical raw material that can be widely used in chemical industry, textile, metallurgy, papermaking, water treatment, coatings, glass, pesticides and other fields. The market demand is relatively broad.

Specifically, in the chemical industry, liquid caustic soda is mainly used in the production of chemical products such as formic acid, oxalic acid, borax, phenol, and sodium cyanide; in the textile field, liquid caustic soda is mainly used as dye reducing agents, desizing agents, and scouring agents. , mercerizing agent and other printing and dyeing auxiliary production scenarios; in the field of pesticides, liquid alkali has strong sterilization ability and is mainly used as a disinfectant for infectious diseases such as chicken pullorum, chicken fever, swine erysipelas, cattle influenza, and foot-and-mouth disease; in the field of glass, liquid alkali is the , the key raw material of diluents and cleaning agents for ceramics; in the field of metallurgy, liquid alkali is the key raw material of metal surface treatment agents.

Liquid caustic soda is a type of basic chemical raw material that is widely used. Driven by the rapid development of its application fields, its market demand continues to increase, driving the continuous increase in production capacity. According to the “China Liquid Alkali Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center, In 2022, my country’s liquid alkali production capacity will exceed 45 million tons, ranking among the top in the world, and it has become the world’s largest producer of liquid alkali.

Domestic liquid alkali manufacturers mainly include Guangdong Dongbo Chemical, Zibo Shunzhize Chemical, Jiangmen Haozhou Chemical, Guangdong Liquid Soda Group, Guangdong Alkali Industry, Wuxi Aniko Chemical, Guizhou Chuanheng Chemical, Hebei Gaohua Chemical, and Hangjin Technology, Shandong Qilu Ronghui Alkali Industry, etc. There are a large number of liquid alkali enterprises in my country, but most of them are small and medium-sized enterprises. The number of large enterprises with large-scale mass production capabilities is relatively small, and the industry concentration is low.

At present, domestic liquid alkali production methods are diverse, mainly including four categories: soda ash causticization method, natural alkali causticization method, diaphragm electrolysis method, and ion exchange membrane method. Among them, the diaphragm electrolysis method is one of the main methods for Chinese enterprises to produce liquid alkali. It refers to using soda ash and caustic soda as raw materials, and removing impurities, clarification, precipitation, sand filtration, hydrochloric acid neutralization, preheating, electrolysis, evaporation, desalination, and concentration. Methods for producing liquid alkali in other links. After years of research and development, my country’s liquid alkali production technology has gradually matured, and the industry has a good foundation for development.

Industry analysts said that liquid caustic soda is an important basic chemical raw material and can be widely used in petrochemicals, textile printing and dyeing, In fields such as metal smelting, as the downstream market develops rapidly, its demand continues to increase, and the market demand space is relatively broad. At present, my country has become the largest producer of liquid alkali in the world, with a large number of companies and relatively mature production methods. However, the concentration of the domestic liquid alkali industry is still relatively low, and the number of enterprises with large-scale mass production capabilities is relatively small. In the future, local enterprises will need to accelerate transformation and upgrading to promote the continuous improvement of the concentration of the domestic liquid alkali industry and the continuous optimization of the industrial structure.
