China’s aluminum sulfate industry is developing well, but there are still many problems in the industry

Aluminum sulfate is a white powder or block with an astringent taste. It easily absorbs moisture and agglomerates when stored in the air for a long time. It is easily soluble in water, and the aqueous solution becomes acidic and is difficult to tolerate in alcohol. The appearance of industrial aluminum sulfate is gray-white flakes, granules or blocks, with a light green color due to the low iron salt content, and the surface turns yellow due to the oxidation of low-priced iron salts. The crude product is gray-white fine-grained porous material. Aluminum sulfate is mainly used as a sizing agent for papermaking and a flocculant for drinking water, industrial water and wastewater treatment. Aluminum sulfate is an important raw material for the production of artificial gemstones and various aluminum salts. Aluminum sulfate is also used for whitening high-grade paper and deodorizing and decolorizing petroleum. It is widely used in the fields of agents, clarifiers, concrete waterproofing agents, etc. Aluminum sulfate is also required for post-film treatment of titanium dioxide and the production of catalyst carriers.

For a long time, China’s chemical industry has continued to develop. Aluminum sulfate is an important chemical raw material, and its industry’s overall production capacity and output have remained at a relatively large scale. According to the released “2021-2026 China Aluminum Sulfate Industry Market In-depth Research and Development Prospects Forecast Report“, in 2020, China The output of the aluminum sulfate industry is nearly 150 tons. But at the same time, Analysts believe that with changes in the industry environment, industrial policies and other factors, China’s aluminum sulfate industry will still Many questions:

1. Environmental protection policies are becoming stricter, restricting the development of the industry

Aluminum sulfate belongs to the chemical industry segment. During the production process, certain waste water, exhaust gas and other pollutants will be produced, which will cause pollution to the surrounding soil and water bodies. It has been the focus of monitoring by the government environmental protection department in recent years. In recent years, with the increasing intensity of environmental protection and the increasing environmental awareness of residents, the environmental issues of the aluminum sulfate industry have received increasing attention. The implementation of the “New Environmental Protection Law” has severely affected the production of aluminum sulfate with serious pollution and irregular production. Enterprises have been hit hard. Some enterprises have stopped operating, and their production capacity utilization rate is low. Enterprises that are operating normally have to invest more funds in improving environmental protection facilities, which increases the production costs of enterprises.

2. There are a large number of manufacturing companies and there is homogeneous competition

In the past two years, domestic safety and environmental protection have been strengthened unprecedentedly, and safety and environmental protection have continued to be under high pressure. The central environmental protection inspection and the centralized rectification of chemical industry parks in coastal areas have restricted the development of downstream dyes, pigments and other industries, and the aluminum sulfate industry has also Affected to a certain extent, some companies were forced to suspend production or withdraw from the market. Large companies took the opportunity to seize the market, and industry concentration increased. But overall, at this stage, there are a large number of enterprises in my country’s aluminum sulfate industry, most of them are small in scale, and the phenomenon of homogeneous competition is serious.

3. The level of production technology needs to be further improved

my country’s aluminum sulfate industry has been developing for many years. The traditional production process has gradually matured, but it is increasingly unable to meet the production requirements of modern society. How to develop a more green, environmentally friendly, efficient and low-consumption process route to improve reaction yield and product purity, Quality has become the top priority for the development of the industry. However, there are currently common problems in domestic aluminum sulfate such as low investment enthusiasm, weak market awareness, and weak awareness of innovation. The industry’s overall technological innovation and scientific research and development capabilities need to be strengthened, and the technical level needs to be further improved.
