高比表氢氧化钙的发展前景

The calcium hydroxide market has broad prospects. According to statistical analysis by developed countries such as Europe, the United States, and Japan, 10% to 15% of quicklime powder production is used to make calcium hydroxide. According to publicly released data, my country's current quick lime powder production is approximately more than 300 million tons per year. Based on this calculation, the total calcium hydroxide production in my country needs to be in the range of 30 to 45 million tons. At present, the total domestic calcium hydroxide production capacity is approximately 22 million tons, of which the supporting production capacity of dry and semi-dry desulfurization equipment is approximately 12 million tons, accounting for approximately 55% of the production capacity. Therefore, calcium hydroxide still has relatively large development prospects in China, not to mention the slow development of the Chinese and international markets.

According to the development status of China's calcium hydroxide field, the future development trend of the calcium hydroxide market is:

1. Expand the business scale of the enterprise and improve the equipment level. At present, the overall scale of my country's calcium hydroxide manufacturing enterprises is relatively small, dominated by enterprises with an annual output of less than 30,000 tons. Smaller-scale companies still occupy the vast majority of the market, and there are even companies that produce general calcium hydroxide with an annual production capacity of less than 10,000 tons. Due to the current strong market demand, small-scale enterprises that cause high energy consumption, high pollution, and uneconomical scale can still make money. As Yuanjia's environmental protection efforts intensify and labor costs increase, it is estimated that in a few years, non-medium and high-end calcium hydroxide manufacturing enterprises with an annual output value of less than 50,000 tons will gradually be replaced by those with high labor efficiency and strict compliance. Replaced by companies with environmental protection regulations, large production capacity, and strong quality.

2. Adjust product structure and develop and design targeted calcium hydroxide products

At present, calcium hydroxide production is generally expanding faster, but due to serious homogeneity, it is very easy to compete at a low price when the market is saturated, leading to a dilemma of no profit. Therefore, companies that understand technical product research and development capabilities should seize the opportunity to develop various mid-to-high-end calcium hydroxide products with technological content and purpose.

1) Special calcium hydroxide for lubricating oil additives. The Chinese market capacity of this type of calcium hydroxide should be about 20,000 tons. Lubrizol in Zhuhai City alone will have a demand of more than 10,000 tons. Plus the Malaysian and Indian markets, there are countless Thousands of tons of needs. However, the quality of calcium hydroxide used in such products has been criticized and its quality is unstable, which seriously affects the quality of lubricating oil additives and product costs. At present, there is only one company in Denmark that can stably produce this type of high-quality calcium hydroxide, and its price in China is around US$700/ton. If the above calcium hydroxide products can be successfully developed, there will be broad development prospects.

2) High specific surface area calcium hydroxide. High specific surface area calcium hydroxide is a product specially used for dry and semi-dry flue gas denitration in waste incineration flue gas treatment. It is characterized by the BET method specific surface area and porosity of calcium hydroxide. Large, and long-term storage can maintain high specific surface area and high porosity, with high nitrogen and sulfur adsorption rates, thus reducing the use of calcium hydroxide and reducing the processing process under the same dechlorination and desulfurization efficiency. The amount of ash in the Since the fly ash after waste incineration contains harmful gases such as dioxins, it needs to be solidified and landfilled. The reduced use of calcium hydroxide will significantly reduce the cost of ash disposal.

3) Pharmaceutical and food-grade plastic calcium hydroxide. Due to the high threshold and relatively high market price of pharmaceutical and food-grade plastic calcium hydroxide, the products are relatively profitable. At this stage, many companies are in the process of product development or have financing plans. Because the threshold for pharmaceutical-grade products is very high, the procedures are complicated, the success rate is low, and it is not easy to get a choice. The application process for food-grade plastics is relatively simple and easy to get recognized. There are two processing techniques for this type of products: dry and wet methods. The products obtained by the wet method have good purity and high quality, but the processing cost is high and they lack the external impact of the sales market; the quality of the dry method is second, but it also meets the requirements. According to the regulations, the manufacturing focus is low, and dry manufacturing is currently the dominant method.

4) Calcium hydroxide used in plastics, plastics and biochemical industries. This type of calcium hydroxide has strong operability and strict requirements on product quality. Such as halogen-free flame retardants and desulfurization catalysts used in the plastics and electronics industries. In addition, products such as calcium stearate, calcium dihydrogen phosphate, calcium propionate and other products have very high requirements for the raw material calcium hydroxide, which is worthy of in-depth analysis, design and development by enterprises.

3. Effective industrial development planning to prevent excessive concentration of the industrial chain. The majority of end users of calcium hydroxide products are in economically developed cities. At present, Beijing, Jiangsu, Zhejiang, Shandong and the Pearl River Delta region of East China are The usage is relatively large. The production capacity of calcium hydroxide in the above provinces, except Guangdong Province, can basically meet the requirements. However, with the increase in environmental protection and the restrictions on resource extraction in the mining network, some companies have moved to Jiangxi Province, Anhui Province, Guangxi Province and other regions to invest and set up factories, but most of them are still dominated by smaller-scale infrastructure construction. With the continuous economic development of the western region, the market demand for calcium hydroxide will gradually expand, and the basic construction of calcium hydroxide production line equipment is likely to be dominated by the western region. It should be noted that end users of calcium hydroxide products are increasingly focusing on supplying them in bulk, especially environmental protection grade calcium hydroxide customers such as agent gas flue gas desulfurization, waste incineration power generation, and domestic sewage treatment, and their demand is relatively large. customer of. The density of calcium hydroxide is relatively low, so special vehicles must be used for bulk weighing. The long-distance supply cost is relatively high, and it is not suitable for long-distance transportation. Its market sales are semi-limited. Therefore, it is not suitable to centrally build calcium hydroxide production lines in the same area. Each place should invest in and build an appropriate number of calcium hydroxide production lines with a certain size according to the market.

Although currently under pressure from environmental protection regulations, large-scale regulations on the lime powder market and mining have been carried out across the country, and the calcium hydroxide industry has also been greatly affected. However, with the continuous development of market demand, there is still considerable development in the calcium hydroxide field. Chance.
