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
水醋酸钠（工业级)
??在平常假如我们常常运用，能够选择干粉颗粒状聚丙烯酰胺，The classification obtained by the method is different. If the ionic type can be divided into Yin, non, amphoteric and cationic polyacrylamide, if according to the shape, it can be divided into four shapes: colloid, laxity, emulsion and dry powder. Which of these four forms is more suitable for us? The company gives you some suggestions. Next is our experience. I hope you will be interested.
In general, if we often use it, we can choose dry powder granular polyacrylamide. Because of its highest solid content, dry powder polyacrylamide is generally stored in dry and cool places for more than two years, but if mixed with solution, its storage time will be limited. Generally speaking, when the concentration of solution is 0.1%, non-ionic and anionic polyacrylamide will dissolve. The stability of cationic polyacrylamide solution depends on the concentration of the solution. For example, the more concentrated the solution is, the longer the storage time of 3%-5% solution is, but the 3%-5% solution can not be directly used to treat sewage. This solution needs to be diluted before use, and the PH value of cationic polyacrylamide solution is less than 5.5. Stability, if greater than 6.0, will be due to hydrolysis and failure, water medium dispersion polyacrylamide shelf life of six months.
Therefore, polyacrylamide is still a better choice of solids, can be used with the mix, do not cause waste.
Of course, we must pay attention to the conditions and taboos of preserving polyacrylamide. Polyacrylamide is more sensitive to iron ions, calcium ions and magnesium ions than anionic polymers. In particular, iron ions are catalysts for the chemical degradation of all polyacrylamide. Therefore, in the manufacture, handling and storage of polyacrylamide solutions, we must try to avoid iron ions entering and touching the solution. The equipment should be made of plastics, stainless steel, FRP or carbon steel with surface coating resin.由于它的固含般情况下干粉聚丙烯酰胺在干燥、阴凉的当地是寄存二年以上的，但假如配成溶液的话，它的寄存时刻就有限了，一般说，溶液浓度为0.1%的时候，非离子与阴离子聚丙烯酰胺溶液不会超过一周的时刻，阳离子聚丙烯酰胺溶液则不会超过一天，而且溶液的稳定性与溶液的浓度有关，配的浓度越浓，例如3%——5%的溶液寄存时刻越长，但3%——5%的溶液不能直接去处理污水，这种在运用前需要稀释，阳离子聚丙烯酰胺溶液PH值小于5.5的时后比较稳定，假如大于6.0的话，就会由于水解的原因而失效，水介质涣散型聚丙烯酰胺保质期为六个月。

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存时间:随着储存时间的增加，PAM溶液降解越多，粘度越低，絮凝效果越差。通常，阴离子PAM溶液可以储存7天，阳离子PAM溶液可以储存24小时。这是由于酰胺基团的水解和羟基含量的增加。尤其是阳离子基团的影响更为明显。由于分子链刚性的增加，酰胺基除去NH3生成酰亚胺基。
2、温度影响: 0.1液体，当温度达到80 - 90℃时，1800万的分子量会在2 - 4小时内降解到500万左右，并且降解会随着温度的升高而变得越来越快。在25℃的室温下性能稳定。
悬浮在有机溶剂中的单体水溶液与小液珠的聚合称为悬浮聚合，也称为珠聚合。悬浮聚合物主要由单体、引发剂、有机溶液和悬浮剂组成。引发剂溶解在单体水溶液中。分散剂也被称为悬浮剂。其功能是在搅拌下将单体水溶液分散成小液珠，并将其悬浮在有机溶剂中，以防止聚合颗粒在聚合过程中相互粘附。产品的粒度一般为100-2000 μ m
Storage time: With the increase of storag胺称为聚氯化铝或者絮凝剂等等。聚合氯化铝和传统的无机混凝剂的不同在：传统无机混凝剂是低分子结晶盐，聚合氯化铝是由各种不同的化学物质经高温高压聚合而成，絮凝沉淀快速，对管道设备腐蚀性小，净水效果优异，能较好的去除水中各种有害重金属离子。
销售凝剂。聚合氯化铝具有絮凝体生成快、沉降性能好、水中碱度消耗低的优点，尤其对水温、酸碱度、浊度和有机物含量的变化适应性强。事实上，聚合氯化铝的整个絮凝过程也是一个失稳过程。所谓失稳，就是让胶体粒子失去稳定性的过程。原本均匀分散在液体中的固体颗粒结合成大颗粒，然后沉淀出来，超过了净水的目的。影响其有效性的因素也很多，如溶液的PH值、温度、搅拌速度、搅拌时间、水体特性等。现阶段，由于它的诸多优点，很受大家的欢迎。目前，我们还开发了复合无机高分子絮凝剂。这类絮凝剂的絮凝特性和沉降性能会在聚合氯化铝的水平上更进一步，相信未来会占据很大的销售市场！
在处理污水时怎么样选择适用的聚合氯化铝，在处理污水通常使用聚合氯化铝，无论是在产品质量上还是在产品价格上，任何消费者都希望自己购买的产品是优异的，质量才是消费者选择的一个重要标准。
先确定污水处理选用的产品种类，可以根据采购净水剂聚合氯化铝的用途来说，聚合氯化铝可以分为工业级，饮水级，食品级等等，不同行业使用的种类也不同，净水剂聚合氯化铝使用范围较为广泛，水处理是净水剂聚合氯化铝的重要方面，在具体选购时还是要依据水处理的效果。
聚合氯化铝净水药剂的外观，颜色，气味，澄清度，固体性状等等可以直接看出水处理药剂的真假以及质量，对聚合氯化铝性能的分辩有直接帮助，可以从以下几点鉴别聚合氯化铝的性能：
1、重要的化学反应，比方离子反应。
2、酸碱度，正常为1％水溶液的酸碱度为依据。使用注意事项一：溶解搅拌
聚丙烯酰胺外观为白色结晶体颗粒，一般为60-80目之间，在使用时需要用洁净的自来水按配比浓度充分溶解，一般溶解搅拌时间不应低于一小时。冬季气温较低时应延长溶解搅拌时间。很多时候应溶解
搅拌时间过短造成PAM未充分溶解，在污水中无法有效的进行吸附架桥、网捕等形式达到快速的絮凝效果。
聚丙烯酰胺使用注意事项二：配置浓度
聚丙烯酰胺配置浓度一般为0.1%-0.3%用于即可适用于絮凝沉淀(需根据PAM分子量大小或根据沉淀速度而定)。城市和工业污泥脱水时配置浓度为0.2%-0.5%之间(需根据污泥浓度大小来调配配置浓度)。
PAM配置浓度的大小完全取决于污水、污泥的浓度，污水中杂质过大时聚丙烯酰胺配置浓度应增加。
聚丙烯酰胺使用注意事项：型号选择
聚丙烯酰胺型号大致可分为常用三种：阴离子型、阳离子型、非离子型，阴离子适用于污水絮凝、沉淀、助降、澄清等，也可用于无机污泥脱水使用。
不同类型聚丙烯酰胺的特性：
阳离子聚丙烯酰胺适用于复杂水质的絮凝、沉降、脱色、澄清等，城市污泥脱水、有机污泥脱水等。。
阴离子型适用于中性及弱碱性无机污水絮凝沉降、污泥脱水。
阳离子型PAM适用于有机污泥的絮凝沉降、污泥脱水。
非离子型聚丙烯酰胺更适用弱酸性污水絮凝沉降及污泥脱水。ize of the product is generally 100-2000 um.
2、乳液聚合的不同之处在于单体溶液的分散程度相对较低，其通常作为珠粒悬浮在有机相中。因此，所用的有机载体是比重较大的溶剂，如二甲苯、甲基氯乙烯等。分散剂通常不使用高活性乳化剂；搅拌强度也低于乳液聚合。悬浮聚合得到的产品为颗粒状，使用方便。
3、在悬浮聚合溶液中，在悬浮剂如Span60、无机酰胺、C12-C18脂肪酸钠或乙酸丁酸纤维的存在下，丙烯酰胺水溶液在汽油、二甲苯和甲基氯乙烯中形成稳定的悬浮液以引发聚合。悬浮聚合结束后，共沸脱水、分离、干燥，得到珠状或粉末状产品。在聚合过程中加入无机盐氯化钠、纳米3或Na2NO3可以调节体系的表面张力，提高悬浮稳定性，但对聚合过程影响不大。然而，加入少量的单羧酸盐、二羧酸盐或多羧酸盐通常会增加产物的相对分子量并降低聚合速率The dispersion of monomer solution is relatively low, and it is usually suspended in organic phase as beads. Therefore, the organic carriers used are solvents with large proportion, such as xylene, methyl vinyl chloride and so on. Dispersants usually do not use highly active emulsifiers, and the stirring strength is lower than that of emulsion polymerization. The product obtained by suspension polymerization is granular and easy to use.
3. In suspension polymerization solution, in the presence of suspension agents such as Span60, inorganic amides, C12-C18 fatty acid sodium or butyric acid acetate fibers, acrylamide aqueous solution forms stable suspensions in gasoline, xylene and methyl vinyl chloride to initiate polymerization. After suspension polymerization, azeotropic dehydration, separation and drying were carried out to obtain beaded or powdered products. Adding inorganic salts such as sodium chloride, nano-3 or Na2NO3 during the polymerization process can adjust the surface tension of the system and improve the suspension stability, but it has little effect on the polymerization process. However, the addition of small amounts of monocarboxylate, dicarboxylate or polycarboxylate usually increases the relative molecular weight of the product and reduces the polymerization rate.
3. Mechanical effect: Stirring can improve the dissolution rate of PAM dry powder. High stirring speed will cut off the molecular chain of polyacrylamide. It is suggested that the stirring speed be controlled online to 60 rpm/min instead of using high-strength stirring equipment and high-speed conveying equipment.
4. The influence of illumination: illumination will raise temperature, dissolve and degrade polyacrylamide, while direct ultraviolet irradiation will quickly degrade and dissolve. Direct exposure to intense light for 3 - 5 hours will reduce the molecular weight of PAM by 30 - 50
5. Impurities: Dissolving PAM powder, optimizing the use of neutral water, high hardness of water, or containing impurities, will affect the viscosity and use effect of PAM.
3、机械作用效果:搅拌可以提高PAM干粉的溶解速度，高强度搅拌速度会切断聚丙烯酰胺的分子链，建议在线控制搅拌速度至60转/分钟，而不是使用高强度搅拌设备和高速输送设备。
4、光照的影响:光照会升高温度，溶解并降解聚丙烯酰胺，而紫外线的直接照射会迅速降解溶解。直接暴露在强光下3 - 5小时将使pam分子量降低30 - 50
5、杂质的影响:溶解PAM干粉，优选使用中性水，水的硬度大，或者含有杂质，都会影响PAM的粘度和使用效果
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、脱水效率高、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，澄清是极为有效的，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'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
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，但效果是无机絮凝剂的几倍，对于机物污染严重的江河水可采用无机絮凝剂和我公司的阳离子聚丙烯酰胺配合使用效果更好。
3、淀粉厂及酒精厂的流失淀粉酒糟的回收 现在很多淀粉厂的废水内含淀粉很多，现投加阴离子聚丙烯酰胺，使淀粉微粒絮凝沉淀，然后将沉淀物经压滤机压滤变成饼状，可作饲料，酒精厂的酒精也可采用阴离子聚丙烯酰胺脱水，压滤进行回收。
聚丙烯酰胺溶液的价格在8000元至12000元之间，我们计算出1吨聚丙烯酰胺溶液的药费为10元，那么处理1吨污水需要多少聚丙烯酰胺阴离子溶液？"通过大量的试验和各厂家的基本情况，总结出每吨污水所需的溶液量小于2~3kg。3~5kg计算处理一吨砂土，只要设备合适且不浪费，处理成本低至0.3~0.5元，如果战场选用自然降水无滤压降低成本，一吨污水处理成本约为0.1元，因此每个老板的成本价格是可以接受的。

聚丙烯酰胺配置浓度一般为0.1%-0.3%用于即可适用于絮凝沉淀(需根据PAM分子量大小或根据沉淀速度而定)。城市和工业污泥脱水时配置浓度为0.2%-0.5%之间(需根据污泥浓度大小来调配配置浓度)。
PAM配置浓度的大小完全取决于污水、污泥的浓度，污水中杂质过大时聚丙烯酰胺配置浓度应增加。
聚丙烯酰胺使用注意事项：型号选择
聚丙烯酰胺型号大致可分为常用三种：阴离子型、阳离子型、非离子型，阴离子适用于污水絮凝、沉淀、助降、澄清等，也可用于无机污泥脱水使用。
不同类型聚丙烯酰胺的特性：
阳离子聚丙烯酰胺适用于复杂水质的絮凝、沉降、脱色、澄清等，城市污泥脱水、有机污泥脱水等。。
阴离子型适用于中性及弱碱性无机污水絮凝沉降、污泥脱水。
阳离子型PAM适用于有机污泥的絮凝沉降、污泥脱水。
非离子型聚丙烯酰胺更适用弱酸性污水絮凝沉降及污泥脱水。ize of the product is generally 100-2000 um.
2、乳液聚合的不同之处在于单体溶液的分散程度相对较低，其通常作为珠粒悬浮在有机相中。因此，所用的有机载体是比重较大的溶剂，如二甲苯、甲基氯乙烯等。分散剂通常不使用高活性乳化剂；搅拌强度也低于乳液聚合。悬浮聚合得到的产品为颗粒状，使用方便。
3、在悬浮聚合溶液中，在悬浮剂如Span60、无机酰胺、C12-C18脂肪酸钠或乙酸丁酸纤维的存在下，丙烯酰胺水溶液在汽油、二甲苯和甲基氯乙烯中形成稳定的悬浮液以引发聚合。悬浮聚合结束后，共沸脱水、分离、干燥，得到珠状或粉末状产品。在聚合过程中加入无机盐氯化钠、纳米3或Na2NO3可以调节体系的表面张力，提高悬浮稳定性，但对聚合过程影响不大。然而，加入少量的单羧酸盐、二羧酸盐或多羧酸盐通常会增加产物的相对分子量并降低聚合速率The dispersion of monomer solution is relatively low, and it is usually suspended in organic phase as beads. Therefore, the organic carriers used are solvents with large proportion, such as xylene, methyl vinyl chloride and so on. Dispersants usually do not use highly active emulsifiers, and the stirring strength is lower than that of emulsion polymerization. The product obtained by suspension polymerization is granular and easy to use.
3. In suspension polymerization solution, in the presence of suspension agents such as Span60, inorganic amides, C12-C18 fatty acid sodium or butyric acid acetate fibers, acrylamide aqueous solution forms stable suspensions in gasoline, xylene and methyl vinyl chloride to initiate polymerization. After suspension polymerization, azeotropic dehydration, separation and drying were carried out to obtain beaded or powdered products. Adding inorganic salts such as sodium chloride, nano-3 or Na2NO3 during the polymerization process can adjust the surface tension of the system and improve the suspension stability, but it has little effect on the polymerization process. However, the addition of small amounts of monocarboxylate, dicarboxylate or polycarboxylate usually increases the relative molecular weight of the product and reduces the polymerization rate.
3. Mechanical effect: Stirring can improve the dissolution rate of PAM dry powder. High stirring speed will cut off the molecular chain of polyacrylamide. It is suggested that the stirring speed be controlled online to 60 rpm/min instead of using high-strength stirring equipment and high-speed conveying equipment.
4. The influence of illumination: illumination will raise temperature, dissolve and degrade polyacrylamide, while direct ultraviolet irradiation will quickly degrade and dissolve. Direct exposure to intense light for 3 - 5 hours will reduce the molecular weight of PAM by 30 - 50
5. Impurities: Dissolving PAM powder, optimizing the use of neutral water, high hardness of water, or containing impurities, will affect the viscosity and use effect of PAM.
3、机械作用效果:搅拌可以提高PAM干粉的溶解速度，高强度搅拌速度会切断聚丙烯酰胺的分子链，建议在线控制搅拌速度至60转/分钟，而不是使用高强度搅拌设备和高速输送设备。
4、光照的影响:光照会升高温度，溶解并降解聚丙烯酰胺，而紫外线的直接照射会迅速降解溶解。直接暴露在强光下3 - 5小时将使pam分子量降低30 - 50
5、杂质的影响:溶解PAM干粉，优选使用中性水，水的硬度大，或者含有杂质，都会影响PAM的粘度和使用效果
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、脱水效率高、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，澄清是极为有效的，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'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
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，但效果是无机絮凝剂的几倍，对于机物污染严重的江河水可采用无机絮凝剂和我公司的阳离子聚丙烯酰胺配合使用效果更好。
3、淀粉厂及酒精厂的流失淀粉酒糟的回收 现在很多淀粉厂的废水内含淀粉很多，现投加阴离子聚丙烯酰胺，使淀粉微粒絮凝沉淀，然后将沉淀物经压滤机压滤变成饼状，可作饲料，酒精厂的酒精也可采用阴离子聚丙烯酰胺脱水，压滤进行回收。
