（PAM）是一种线型水溶性高分子，是水溶性高分子化合物中应用最为广泛的品种之一，PAM及其衍生物

可以用作高效的絮凝剂、增稠剂、纸张增强剂以及液体的减阻剂，广泛应用于水处理、造纸、石油、煤

炭、矿冶、地质、轻纺、建筑等工业部门。

　   非离子聚丙烯酰胺

用途： 1、污水处理剂　 当悬浮性污水显酸性时，采用非离子聚丙烯酰胺作絮凝剂较为合适，这是PAM

起吸附架桥作用，使悬浮的粒子产生絮凝沉淀，达到净化污水的目的。也可用于自来水的净化，尤其是

和无机絮凝剂配合使用，在水处理中效果。

      2、纺织工业助剂　 添加一些化学品可配成化学资料，用于纺织品上浆。

      3、防沙固沙　 将非离子聚丙烯酰胺溶成0.3%浓度加入交联剂，喷洒在沙漠上可起到防沙固沙的

作用。

      4、土壤保湿剂　 用作土壤保湿剂和各种改性聚丙烯酰胺的基础原料。

　   阳离子聚丙烯酰胺:

用途：1、污泥脱水   根据污泥性质可选用本产品的相应牌号，可有效在污泥进入压滤之前进行重力污

泥脱水。脱水时，产生絮团大，不粘滤布，在压滤时不流散、用量少、脱水效***、泥饼含水率在80%以

下。

         2、污水和有机废水的处理　 本产品在酸性或碱性介质中均呈现阳电性，这样对污水中悬浮颗

粒带阴电荷的污水进行絮凝沉淀，澄清是极为***，如酒精厂废水、啤酒厂废水、味精厂废水、制糖

厂废水、肉食品厂废水、饮料厂废水、纺织印染厂的废水等。用阳离子聚丙烯酰胺要比用阴离子聚丙烯

酰胺，非离子聚丙烯酰胺或无机盐效果要高数倍或数十倍，因为这类废水普遍带有阴电荷。

         3、自来水厂水处理絮凝剂　 该产品具有用量少、效果好、成本低等特点。特别是和无机絮凝

剂复配使用效果更好。

         4、油田化学品　 如粘土防膨剂、油田酸化用稠化剂品等。(PAM) is a linear water-

soluble polymer, which is one of the most widely used varieties of water-soluble polymer 

compounds. PAM and its derivatives can be used as efficient flocculants, thickeners, paper 

enhancers and liquid drag reducing agents. They are widely used in water treatment, paper 

making, petroleum, coal, mining, metallurgy, geology, light textile, construction and other 

industrial sectors.

Nonionic polyacrylamide

Uses: 1. When the suspended sewage is acidic, it is more appropriate to use non-ionic 

polyacrylamide as flocculant. This is because PAM acts as an adsorption bridge to make 

suspended particles flocculate and precipitate, so as to purify the sewage. It can also be 

used to purify tap water, especially in combination with inorganic flocculants, and has the 

best effect in water treatment.

2. Adding some chemicals to textile industry auxiliaries can be used to compose chemical 

data for textile sizing.

3. Dissolve non-ionic polyacrylamide into 0.3% concentration and add crosslinking agent in 

sand control and sand fixation. Spraying on desert can play a role in sand control and sand 

fixation.

4. Soil moisturizers are used as basic materials of soil moisturizers and various modified 

polyacrylamides.

Cationic polyacrylamide:

Usage: 1. Sludge dewatering can choose the corresponding brand of this product according to 

the nature of sludge, which can effectively dewatering gravity sludge before the sludge 

enters the filter press. When dewatering, it produces large flocs, non-sticking filter 

cloth, non-dispersing, less dosage, high dewatering efficiency and less than 80% moisture 

content of mud cake.

2. The treatment of sewage and organic wastewater shows positive electricity in acidic or 

alkaline medium, so flocculation and precipitation of sewage with negative charge of 

suspended particles in sewage is very effective, such as wastewater from alcohol factory, 

brewery, monosodium glutamate factory, sugar factory, meat food factory, beverage factory 

and textile printing and dyeing factory. Cationic polyacrylamide is several or tens of 

times more effective than anionic polyacrylamide, nonionic polyacrylamide or inorganic 

salts, because such wastewater generally has negative charges.

3. Water treatment flocculant in Waterworks has the characteristics of low dosage, good 

effect and low cost. Especially, the combination of inorganic flocculant and inorganic 

flocculant has better effect.

4. Oilfield chemicals such as clay anti-swelling agents and thickeners for oilfield 

acidification.

5. Paper reinforcer cationic PAM is a water-soluble cationic polymer containing carbamoyl 

group. It has the functions of reinforcement, retention and filter aid. It can effectively 

improve the strength of paper. At the same time, the product is also a highly effective 

dispersant.

Anionic polyacrylamide

Uses: 1. Industrial wastewater treatment has the best effect on sewage treatment, such as 

coarse suspended particles, high concentration, positive charges of particles, neutral or 

alkaline PH value of water, iron and steel plant wastewater, electroplating plant 

wastewater, metallurgical wastewater, coal washing wastewater, etc.

2. Drinking water treatment in many Waterworks of our country comes from rivers. The 

content of sediment and minerals is high and turbid. Although it can&＃39;t meet the 

requirements after sedimentation and filtration, it needs to add flocculant. The dosage of 

flocculant is 1/50 of inorganic flocculant, but the effect is several times that of 

inorganic flocculant. Inorganic flocculant and cationic flocculation of our company can be 

used for river water seriously polluted by organic matter. The effect of acrylamide is 

better.

3. Recycling of lost starch grains in starch factories and alcohol factories now contains a 

lot of starch in the wastewater of many starch factories. Anionic polyacrylamide is added 

to flocculate and precipitate starch particles, and then the precipitate is filtered into 

cake shape by pressure filter, which can be used as feed. Alcohol in alcohol factories can 

also be dehydrated by anionic polyacrylamide and reclaimed by pressure filter.

         5、 造纸助剂　 阳离子PAM纸张增强剂是一种含氨基甲酰基的水溶性阳离子聚合物，具有增强

、助留、助滤等功能，可有效地提高纸的强度，同时该产品也是一种高效分散剂。

　   阴离子聚丙烯酰胺

用途：1、工业废水处理　 对于悬浮颗粒较粗、浓度高、粒子带阳电荷，水的PH值为中性或碱性的污水

，钢铁厂废水、电镀厂废水、冶金废水、洗煤废水等污水处理，效果。

     2、饮用水处理　 我国很多自来水厂的水源来自江河，泥沙及矿物质含量高，比较浑浊，虽经过沉

淀过滤，仍不能达到要求，需要投加絮凝剂，投加量是无机絮凝剂的1/50，但效果是无
