The structure of the micelle electric double layer determines that the concentration of counter ions is the largest on the surface of the colloidal particles, and the concentration of counter ions decreases with the distance from the surface of the colloidal particles to the outside, which is finally equal to the ion concentration in the solution. When the electrolyte is added to the solution to increase the ion concentration in the solution, the thickness of the diffusion layer decreases.
Sewage treatment
Polyaluminum chloride products are widely used in the sewage treatment industry, especially products such as polyaluminum chloride and polyacrylamide have outstanding effects in sewage flocculation and sedimentation, and are widely used in daily sewage, chemical wastewater, and industrial sewage treatment.
mining
Polyaluminum chloride flocculant has a very good performance in the mining industry, and has been used for ore washing and mineral separation. On the one hand, the water is separated from the gangue, which is convenient for water reuse; on the other hand, the polyacrylamide dewaters the generated sludge.
paper industry
In the paper industry, polyaluminum chloride is mainly used for rosin neutral sizing precipitant, retention aid, drainage aid, and can also be used to control well-known obstacles. And as a scavenger for anion magazines, etc.
Agriculture
Soil crusts exist on the soil surface with high density, small pores, and low saturated hydraulic conductivity, which can hinder soil water infiltration, increase surface runoff and hinder seed germination. Polyacrylamide increases soil moisture content, soothes soil crust formation, and increases water infiltration.
Textile industry
The wastewater produced by the textile printing and dyeing industry has the characteristics of large water volume, deep chroma, and high pollutant content in the agricultural production system. It is one of the more difficult wastewaters to treat in industrial wastewater. The flowers are solid and large, the settling speed is fast, and the treatment effect is obvious. The study found that polyaluminum chloride can be used for the anti-wrinkle function of cloth.
Daily chemical industry
Basic aluminum chloride has obvious effect on the flocculation and precipitation of wastewater in daily chemical production; in addition, white polyaluminum chloride is a high-grade product in water purification flocculants, which belongs to food-grade polyaluminum chloride, and is also used in pharmaceuticals and cosmetics , The beauty industry is used as raw materials or additives.
