Drinking-Water Grade High Purity PAC 28% CAS 1327-41-9 Powder Polyaluminum Chloride

Product Description

Product Description

Polyaluminum chloride (PAC) is a widely used inorganic polymer coagulant known for its high efficiency and versatility in water treatment. It is a water-soluble inorganic polymer compound that lies between aluminum chloride (AlCl₃) and aluminum hydroxide (Al(OH)₃). The chemical formula of PAC is typically represented as Al2Cln(OH)6-n, where n is a number between 1 and 5, and m represents the degree of polymerization.
Chemical Properties
• Appearance: Liquid PAC is a pale yellow to brownish-yellow suspension, while solid PAC is a pale yellow to orange-yellow crystalline powder.
• Solubility: Highly soluble in water, with rapid hydrolysis that leads to coagulation, adsorption, and precipitation.
• pH Range: Effective over a broad pH range (typically 5-9), with minimal impact on the pH of treated water.
• Stability: Stable at room temperature but decomposes at high temperatures (above 110°C), releasing hydrogen chloride (HCl) gas.

Application

Water Treatment Field
• Drinking Water Purification: Used to remove suspended solids, colloids, organic matter, and microorganisms from water, thereby enhancing the transparency and safety of water quality.
• Industrial Water Treatment: Used to remove impurities and harmful substances from water to ensure that the quality of industrial water meets production requirements.

Improving Paper Quality
• Enhancing Paper Strength and Appearance: By increasing the retention rate of fibers and fillers, polyaluminum chloride helps produce paper with higher strength, smoother surface, and more uniform appearance. This is especially suitable for the production of high-quality printing and writing paper.
• Increasing Paper Whiteness and Opacity: In some applications, polyaluminum chloride can also improve the whiteness and opacity of paper, thereby enhancing the overall quality of the paper.

Moisturizing and Balancing Skin Oil LevelsIn some specific skincare formulations, by precisely adjusting the concentration of polyaluminum chloride, the product can achieve better moisturizing effects and balance the skin's oil levels. This application not only enhances the user experience but also ensures the mildness and safety of the product.
