Guangxi polyaluminium chloride supplier: to introduce you to the role and principle of polyaluminium chloride
Polyaluminum chloride can be used as many items, among which it is not only suitable for sewage purification, but also as other items in textile and other industries. This is mainly related to the function and principle of the product, so we need to understand itFunction and Principle of Polyaluminum ChlorideDetailed knowledge.
1. Polyaluminum chloride flocculation: When using PAM flocculation, it is related to the surface characteristics of the flocculated material, especially the dynamic potential, viscosity, turbidity and hydrogen ion concentration index of the suspension. The dynamic potential on the surface of the particle is the particle. The reason for the inhibition is the addition of PAM with opposite surface charges, which can reduce the fast dynamic potential and condense. When polyaluminum chloride solid polyaluminum chloride is diluted into a liquid, first according to the raw water, a small amount of test is carried out before use to obtain a better dosage.
2. Polyaluminum (Al) chloride adsorption bridging: PAM molecular chains are fixed on the surface of different particles, and polymer bridges are formed between each particle, so that the particles form aggregates and settle. Polyaluminium ferric chloride Polyaluminium chloride is an inorganic polymer coagulant. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, inorganic polymer water with larger molecular weight and higher charge can be prepared. The characteristics of the treatment chemical depend mainly on the working principle of the pressure atomizer.
3. Surface adsorption of polyaluminum chloride (also known as PAC, polyaluminum and polyaluminum chloride): various adsorption of PAM molecules by reactive group particles.
4. Polyaluminum chloride reinforcement: PAM molecular chain and dispersed phase entangle the dispersed phase together through various mechanical, physical, chemical and other effects to form a network, thereby playing a reinforcing role. Polyaluminum chloride is mainly used in two aspects of the paper industry: one is to improve the retention rate of fillers, pigments, etc., to reduce the loss of raw materials and environmental pollution. The other is to increase the strength of the paper (including dry strength and wet strength). In addition, the use of polyaluminum chloride can also improve the tear resistance and porosity of the paper, thereby improving the visual and printing properties.
In the mining process, a large amount of water is usually used, and the useful solids in the water are usually recovered at the end, and the wastewater is purified and recycled. The application of polyaluminum chloride flocculation can promote the sinking of particles, the clarification of liquid and the dehydration of mud cake, thereby improving production efficiency, reducing tailings loss and water consumption, reducing equipment investment and processing costs, and avoiding environmental pollution. Uranium ore extraction is one of the earlier important application fields of polyaluminium chloride. When leaching uranium ore with acid or sulfonate solution, the addition of polyaluminum chloride is very effective for the enrichment and filtration of the leached material.
Polyaluminum chloride is used as a sizing agent and finishing agent for fabric treatment, which can produce a soft, anti-wrinkle and anti-mold protective layer. Using its strong hygroscopicity, the breaking rate in the spinning process can be reduced. Polyaluminum chloride as a post-treatment agent can prevent static electricity and flame retardancy of fabrics. When used as a printing and dyeing auxiliary, polyaluminum chloride can make the product's adhesion fastness and brightness high, and can also be used as a non-silicon polymer stabilizer for bleaching.
