There is an imbalance between supply and demand in the aluminum sulfate market. Enterprises should produce according to market demand.

Aluminum sulfate, also known as aluminum sulfate hexahydrate, has a chemical formula of Al₂(SO₄)₃, CAS number 10043-01-3, and a molecular weight of 342.15, appearance is colorless or white crystal, odorless, slightly sweet taste, soluble in water, insoluble in ethanol, etc. The industrial product is in the form of gray-white flakes, granules or blocks, and the crude product is gray-white porous material with fine crystal structure, non-toxic, and the dust is irritating to the eyes. The industrial production process of aluminum sulfate is relatively mature. It is mostly produced by the pressure reaction of bauxite and sulfuric acid, or by decomposing alunite, kaolin and alumina-containing silicon raw materials with sulfuric acid. Different grades of aluminum sulfate have different Fe contents and different colors. Commonly used aluminum sulfate is generally divided into aluminum sulfate for high-grade paper, aluminum sulfate for medium and low-grade paper, aluminum sulfate for water treatment, etc. In addition, aluminum sulfate has two forms: solid and liquid. Solid aluminum sulfate is mainly sold when sold. Solid aluminum sulfate can be divided into refined aluminum sulfate and crude aluminum sulfate according to the content of insoluble matter.

Aluminum sulfate is an important inorganic substance that is often used as an industrial reagent. For example, it is used as a paper sizing agent in papermaking to improve the water resistance and anti-seepage properties of paper; it is used as a flocculant in water treatment and is added to water. Aluminum sulfate can produce colloidal aluminum hydroxide flakes that can adsorb and precipitate bacteria, colloids and suspended matter to control the color and smell of water; it is mainly used as an antiperspirant cosmetic raw material in cosmetics. In addition, aluminum sulfate can also be used in the fuel industry, fire protection industry and as raw materials for aluminates. Overall, among the downstream applications of aluminum sulfate, papermaking accounts for the highest proportion, followed by water treatment, and applications in other fields account for relatively low proportions.

After years of development, my country’s aluminum sulfate industry has many manufacturers, such as Zibo Guangzheng Aluminum Salt Chemical Co., Ltd., Henan Chenming Environmental Protection Technology Co., Ltd., Tianjin Tongxin Chemical Factory, Henan Baoxin Environmental Protection Technology Co., Ltd., Henan Levitt Chemical Technology Co., Ltd., Henan Box Environmental Protection Technology Co., Ltd., etc. According to the “China Aluminum Sulfate Industry Market In-depth Research and Development Prospects Forecast Report 2021-2026” released by the Industrial Research Center, 2021 In 2017, my country’s aluminum sulfate output was nearly 185 tons. Overall, my country’s aluminum sulfate industry has a large number of manufacturing companies, but most of them have small production scales and relatively single products, leading to serious homogenization competition.

Industrial analysts said that my country’s aluminum sulfate industry has been developing for many years, and in the context of continued growth in output, it has basically formed a situation of oversupply. . Although its traditional production process is relatively mature, it consumes a lot of energy and pollutes the environment seriously, and cannot meet the current needs of clean production. In the context of my country’s increasingly strict environmental protection policies, failure to develop green, environmentally friendly, efficient and low-energy production processes means that they will eventually be eliminated by the market. Therefore, aluminum sulfate production enterprises should actively carry out product research and development, promote industrial reform, produce according to market demand, and avoid blindly expanding production and increasing market burden.
