Caustic soda has wide application fields but low industry concentration

Caustic soda is also called sodium hydroxide, caustic soda, caustic soda and caustic soda. Its chemical formula is NaOH. It appears as a white crystalline powder and is highly alkaline, highly corrosive, moderately toxic and highly water-absorbent. According to different appearance forms, caustic soda can be divided into liquid caustic soda and solid caustic soda. Liquid caustic soda, also known as liquid soda, is a colorless and transparent liquid with a concentration of usually 30.0%-32.0% or 40.0%-42.0%. Solid caustic soda, also known as solid soda, is a colorless and transparent crystal. It has the characteristics of simple production, low production cost, and It has the advantages of good heavy metal sedimentation and phosphorus removal effects.

Raw salt is one of the main raw materials for making caustic soda and occupies an important position in inorganic chemical products. my country has a vast territory and abundant salt resource reserves. It is the world’s largest raw salt producer, which provides strong support and guarantee for the development of my country’s caustic soda industry. However, in recent years, affected by supply-side reforms and environmental protection policies, my country’s raw salt production has declined. According to data from the National Bureau of Statistics, my country’s raw salt production reached 51.546 million tons in 2021, a year-on-year decrease of 3.9%. East China is the main producing area of ​​raw salt in my country, and its raw salt output accounts for nearly 30% of the country’s total output.

Caustic soda is an important chemical product with a wide range of applications, including alumina, light industry, printing and dyeing, chemical industry, viscose staple fiber, papermaking, petroleum, etc. As an important industrial raw material, alumina has a vast market space. It has mechanical properties, hardness and chemical corrosion resistance, and is widely used. A large amount of caustic soda is used in the production process of alumina, and its market demand reaches 31.5%. It is the main application field of caustic soda. . According to the “2022-2027 China Caustic Soda Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center, in recent years In the past, as downstream demand continues to grow, my country’s caustic soda output has shown a continued growth trend. According to data from the National Bureau of Statistics, my country’s caustic soda output will reach 38.913 million tons in 2021, an increase of 2.481 million tons compared with 2020 and a year-on-year increase of 5.2%.

my country’s caustic soda industry has a low degree of concentration and fierce competition among enterprises. According to statistics from the China Chlor-Alkali Industry Association, the caustic soda production capacity of my country’s caustic soda production enterprises will reach 45.634 million tons in 2021, a year-on-year increase of 1.42%. The well-known caustic soda companies in my country include Zhongtai Chemical, Liaocheng Xinyuan, Xinjiang Tianye, Haobang Chemical, Chlor-Alkali Chemical and Yaxing Chemical. Zhongtai Chemical’s main business is polyvinyl chloride resin (PVC), ion membrane caustic soda, nano-PVC, hydrochloric acid and other chlor-alkali chemical products. In 2021, Zhongtai Chemical’s caustic soda production capacity exceeded 1 million tons, ranking in the leading position in the industry.

Industry analysts said that due to the sufficient supply of raw materials, the output of caustic soda, as an important chemical raw material, continues to grow, which provides strong support for the development of downstream industries. Support and security. Caustic soda has a wide range of applications, and the rapid development of the alumina industry will drive the demand for caustic soda in my country to continue to increase. There are many caustic soda production enterprises in my country, but the number of enterprises with a production capacity exceeding 1 million tons is relatively small, and the growth rate of production capacity is slow. This is the main challenge facing the development of my country’s caustic soda industry.
