Polyaluminum chloride (PAC) plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are rich and diverse. This article will detail the upstream and downstream associated products of polyaluminium chloride.

1. upstream related products

1. Bauxite

Bauxite is one of the main raw materials of polyaluminum chloride, and its main component is alumina (Al2O3). After the bauxite ore is treated by crushing, grinding, pickling and other processes, the aluminate solution for the production of polyaluminum chloride can be obtained.

2. Hydrochloric acid

Hydrochloric acid is another important raw material in the production process of polyaluminium chloride, which is used to adjust the pH value of the solution and promote the hydrolysis and polymerization of aluminum salts.

3. Alkali

In the production process of polyaluminum chloride, alkali is mainly used to neutralize hydrochloric acid and adjust the pH value of the solution to promote the polymerization reaction. Commonly used alkali sodium hydroxide and calcium hydroxide.

2. downstream related products

1. Water treatment agent

Polyaluminum chloride as a high-efficiency inorganic water treatment agent, is widely used in domestic water, industrial water and wastewater treatment and other fields. Through charge neutralization, adsorption bridging and other effects, it can effectively remove suspended solids, colloidal substances and chromaticity in water and improve water quality.

2. Papermaking auxiliaries

Polyaluminum chloride can be used as papermaking auxiliaries in the paper industry to improve the strength and whiteness of paper and improve the performance of paper. It helps to improve the quality and yield of paper by promoting the dispersion and flocculation of pulp fibers and improving the dewatering performance of pulp.

3. ceramic additive

polyaluminum chloride can be used as a ceramic additive to improve the performance of ceramic materials. It improves the density and mechanical properties of ceramic products by adjusting the viscosity, fluidity and stability of the ceramic slurry.

4. oilfield chemical

in the process of oil field exploitation, polyaluminum chloride can be used as oilfield chemicals to improve the clarity and filtration performance of the produced fluid. By removing suspended solids and colloidal substances in the produced fluid, the viscosity of the produced fluid is reduced, and the efficiency of oil field exploitation is improved.

In short, polyaluminium chloride has a wide range of applications in the field of chemical production raw materials, its upstream and downstream related products cover water treatment agents, paper additives, ceramic additives and oilfield chemicals and other fields.
