Industrial environmental water purification materials, polyaluminium chloride and polyaluminum chloride How to distinguish? Where is the difference between polyaluminium chloride and polyaluminium chloride? 1. From the point of view of industrial water treatment, polyaluminium chloride has an excellent effect in river water purification. The treated water has outstanding effect and the water quality is relatively soft, which will not cause the fabric to be hard and so on. However, polyaluminum chloride Waste water purification process of steel mills, paper mills, sewage plants and other short time, quick, clear water quality after treatment, easier to meet emission standards. 2, the appearance of polyaluminium chloride is yellow, and polyaluminum chloride is red or brown. 3, from the processing of raw materials point of view, polyaluminum chloride, in particular, the level of drinking water needs to use aluminum hydroxide powder material to process the production, and polyaluminum chloride need aluminum calcium powder as raw material for processing. 4, from the functional point of view PAC PAC can only be used in industrial water treatment, and PAC can be used for drinking water and industrial water treatment. Here we will introduce the characteristics of PACIF performance: 1, hydrolysis speed, hydration weak. The formation of dense alum, settling speed. Little affected by changes in water temperature, to meet the flow in the process of shear requirements. 2, poly-iron use and packaging purposes and precautions with the same basic aluminum chloride. 3, PAC ferric chloride flocculant solid product is brown, reddish-brown powder, easily soluble in water. 4, poly-iron can effectively remove the source of aluminum ions and aluminum salt coagulated residual free aluminum ions in the water. 5, PAC, Fe dosage, good treatment effect, save 10-20% of the cost than other coagulants. 6, poly-iron wide range of applications, drinking water, industrial water, domestic water, domestic sewage and industrial wastewater treatment. Advantages of high-purity, iron-free white polymeric aluminum chloride White polymeric aluminum chloride as a sizing agent must have a 30% aqueous solution that is still clear and transparent without any water-insolubles and has a very low iron content. At present, only a few districts in the country can do this standard. White polymeric aluminum chloride can also be used in pharmaceutical, cosmetic and industrial catalysts as raw materials or additives, especially in the paper industry, high purity (iron-free) white polyaluminum chloride as papermaking neutral sizing agent, currently in foreign countries Has been widely used. It can replace aluminum sulfate, significantly improve paper quality, reduce costs. As the polymer flocculant non-toxic, in a variety of food, candy, alcohol, feed products, solid-liquid sedimentation separation process also has varying degrees of application. High purity iron-free white polyaluminum chloride is the high-end product of water purification flocculant introduced in China in recent years. It has a white color, easy to dissolve, clear and transparent aqueous solution and other characteristics, is being accepted by more and more industries and use. High-purity iron-free white polyaluminium chloride in medicine, cosmetics, electronics industry's advantage is the ordinary roller-type aluminum unmatched. In recent years, aluminum sulfate has been widely used in papermaking sizing.
