Polyacrylamide (PAM) is a kind of linear water-soluble polymer, which is one of the most widely used varieties in water-soluble polymer compounds. PAM and its derivatives can be used as efficient flocculant, thickener, paper enhancer and liquid drag reducer, which are widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, light textile, construction and other industrial sectors.

　　Nonionic polyacrylamide

　　Uses: 1. Sewage treatment agent when the suspended sewage is acidic, it is more appropriate to use non-ionic polyacrylamide as flocculant, which is PAM plays the role of adsorption bridging, so that the suspended particles produce flocculation sedimentation, so as to achieve the purpose of sewage purification. It can also be used in the purification of tap water, especially in combination with inorganic flocculant.

　　2. Textile industry auxiliaries can be made into chemical materials by adding some chemicals for textile sizing.

　　3. In order to prevent and fix sand, the non-ionic polyacrylamide was dissolved into 0.3% concentration and added with crosslinking agent. Spraying on the desert can play the role of preventing and fixing sand.

　　4. Soil humectant is used as the basic material of soil humectant and various modified polyacrylamide.

　　Cationic polyacrylamide:

　　Uses: 1. According to the properties of sludge, the corresponding brand of this product can be selected for sludge dewatering, which can effectively carry out gravity sludge dewatering before the sludge enters the filter press. During dewatering, it produces large floccules, does not stick to the filter cloth, does not disperse during pressure filtration, uses less, has high dewatering efficiency, and the moisture content of mud cake is below 80%.

　　2. Treatment of wastewater and organic wastewater this product presents positive electricity in acidic or alkaline medium, so it is very effective to flocculate and precipitate the wastewater with negative charge in the wastewater, such as wastewater from alcohol factory, brewery, monosodium glutamate factory, sugar factory, meat and food factory, beverage factory, textile and dyeing factory, etc. The effect of cationic polyacrylamide is several times or tens of times higher than that of anionic polyacrylamide, nonionic polyacrylamide or inorganic salt, because this kind of wastewater generally has negative charge.

　　3. The flocculant for water treatment in Waterworks has the characteristics of low dosage, good effect and low cost. In particular, the effect is better when combined with inorganic flocculant.

　　4. Oilfield chemicals such as clay antiswelling agent, thickening agent for oilfield acidizing, etc.

　　5. Cationic PAM is a kind of water-soluble cationic polymer containing carbamoyl group. It has the functions of strengthening, retention and drainage, which can effectively improve the strength of paper. At the same time, it is also a high-efficiency dispersant.

　　Anionic polyacrylamide

　　Uses: 1. Industrial wastewater treatment has the best effect for the wastewater with coarse suspended particles, high concentration, positive charge particles, neutral or alkaline pH value of water, wastewater from iron and steel plant, electroplating plant, metallurgical plant and coal washing plant.

　　2. Drinking water treatment The water source of many Waterworks in China comes from rivers with high content of sediment and minerals, which is relatively turbid. Although it is filtered by sedimentation, it still can not meet the requirements. Flocculant needs to be added. The dosage is 1 / 50 of inorganic flocculant, but the effect is several times of inorganic flocculant. For rivers with serious organic pollution, inorganic flocculant and cationic polyacrylamide of our company can be used to make the water quality better It's better to use it.

　　3. Recovery of starch distiller's grains lost from starch and alcohol plants at present, many starch plants contain a lot of starch in their wastewater. Now anionic polyacrylamide is added to flocculate and precipitate starch particles, and then the precipitate is pressed into cake shape by filter press, which can be used as feed. Alcohol in alcohol plants can also be dehydrated by anionic polyacrylamide and recycled by filter press.
