Calcium hydroxide is widely used and local companies still have great room for improvement.

Calcium hydroxide is commonly known as slaked lime or slaked lime, and its chemical formula is Ca(OH)2. It is a white powdery solid that is slightly soluble in water. It is insoluble in alcohol, soluble in ammonium salts and glycerol, and can react with acids to generate the corresponding calcium. Salt is an inorganic compound. At present, there are three main methods for preparing calcium hydroxide: carbonization method, Solvay method, and caustic soda method.

According to the “Calcium Hydroxide Industry Investment Feasibility Analysis Report in 2023” released by the Industrial Research Center, the upstream of the calcium hydroxide industry chain For the supply of raw materials such as quicklime, water and other production equipment, my country’s limestone raw material supply is sufficient, providing a stable foundation for the production of sodium hydroxide; the midstream is the production and production of products; the downstream is widely used in food, chemical industry, construction, environmental protection and other fields.

From the food field, calcium hydroxide is one of the important food additives. It can be used as a thickener and regulator for yogurt, juice, candy and other foods. It can also inhibit the growth of microorganisms, regulate acidity, and increase food stability. Sexual effects. As national living standards continue to improve and the demand for leisure meals continues to grow, the market demand for food-grade calcium hydroxide will grow steadily.

From the perspective of environmental protection, calcium hydroxide can neutralize acidic wastewater and remove heavy metal ions in the water. It is an efficient sewage treatment agent. In recent years, with the continuous improvement of my country’s environmental awareness, the demand for calcium hydroxide has continued to grow. In addition, calcium hydroxide can also be used to make soil conditioners, fire retardants, fungicides, etc. In general, driven by downstream market demand, the calcium hydroxide market will continue to expand. my country’s calcium hydroxide market size will be close to 35 billion yuan in 2022, and is expected to exceed 38 billion yuan in 2023.

my country’s calcium hydroxide industry has made certain progress through continuous development, but there is still a certain gap compared with developed countries abroad. At this stage, although there are a large number of calcium hydroxide production enterprises in my country, they are mainly concentrated in the middle and low-end fields. The industrial scale is small and the degree of refinement is low. The development of the middle and high-end markets is slow and unable to meet the diversified needs of the market. There is still a large gap. Room for improvement. At present, domestic calcium hydroxide manufacturers include Zhejiang Tianshi Nanotechnology Co., Ltd., Hunan Xiangyi Calcium Industry Co., Ltd., Anhui Hualong Calcium Industry Co., Ltd., Shandong CITIC Calcium Industry Co., Ltd., Liaoning Bangjia Calcium Industry Co., Ltd., etc.

Industry analysts said that with the continuous development of the industry, the application fields of calcium hydroxide will be further expanded, and in the future, the pharmaceutical, cosmetics and other industries will have The demand for calcium hydroxide will also continue to grow. Driven by downstream market demand, calcium hydroxide has good development prospects. At present, the domestic calcium hydroxide industry is small, scattered and chaotic. As competition in the industry continues to intensify and national environmental protection supervision continues to strengthen, companies with backward production capacity and low production efficiency will gradually be eliminated by the market. Related companies need to continuously improve their production processes and Improve production technology and product quality, and enhance its core competitiveness.
