2、溫度影響: 0.1液體，當(dāng)溫度達(dá)到80 - 90℃時(shí)，1800萬(wàn)的分子量會(huì)在2 - 4小時(shí)內(nèi)降解到500萬(wàn)左右，并且降解會(huì)隨著溫度的升高而變得越來(lái)越快。在25℃的室溫下性能穩(wěn)定。
懸浮在有機(jī)溶劑中的單體水溶液與小液珠的聚合稱(chēng)為懸浮聚合，也稱(chēng)為珠聚合。懸浮聚合物主要由單體、引發(fā)劑、有機(jī)溶液和懸浮劑組成。引發(fā)劑溶解在單體水溶液中。分散劑也被稱(chēng)為懸浮劑。其功能是在攪拌下將全球疫情爆發(fā)下 凈水行業(yè)的路在何方

2020 is destined to be a tough year for donai, with tears, feelings and short joy after victory. In the face of the global explosive epidemic, how will our water purification industry develop Henan anjiajing environmental protection technology, devoted to the production of polyacrylamide poly aluminum chloride poly ferric sulfate? Over 20 years, we have experienced many experiences in Central China, neighboring Hubei
單體水溶液分散成小液珠，并將其懸浮在有機(jī)溶劑中，以防止聚合顆粒在聚合過(guò)程中相互粘附。產(chǎn)品的粒度一般為100-2000 μ m
Storage time: With the increase of storag胺稱(chēng)為聚氯化鋁或者絮凝劑等等。聚合氯化鋁和傳統(tǒng)的無(wú)機(jī)混凝劑的不同在：傳統(tǒng)無(wú)機(jī)混凝劑是低分子結(jié)晶鹽，聚合氯化鋁是由各種不同的化學(xué)物質(zhì)經(jīng)高溫高壓聚合而成，絮凝沉淀快速，對(duì)管道設(shè)備腐蝕性小，凈水效果優(yōu)異，能較好的去除水中各種有害重金屬離子。
非離子型聚丙烯酰胺更適用弱酸性污水絮凝沉降及污泥脫水。ize of the product is generally 100-2000 um.
2、乳液聚合的不同之處在于單體溶液的分散程度相對(duì)較低，其通常作為珠粒懸浮在有機(jī)相中。因此，所用的有機(jī)載體是比重較大的溶劑，如二甲苯、甲基氯乙烯等。分散劑通常不使用高活性乳化劑；攪拌強(qiáng)度也低于乳液聚合。懸浮聚合得到的產(chǎn)品為顆粒狀，使用方便。
3、在懸浮聚合溶液中，在懸浮劑如Span60、無(wú)機(jī)酰胺、C12-C18脂肪酸鈉或乙酸丁酸纖維的存在下，丙烯酰胺水溶液在汽油、二甲苯和甲基氯乙烯中形成穩(wěn)定的懸浮液以引發(fā)聚合。懸浮聚合結(jié)束后，共沸脫水、分離、干燥，得到珠狀或粉末狀產(chǎn)品。在聚合過(guò)程中加入無(wú)機(jī)鹽氯化鈉、納米3或Na2NO3可以調(diào)節(jié)體系的表面張力，提高懸浮穩(wěn)定性，但對(duì)聚合過(guò)程影響不大。然而，加入少量的單羧酸鹽、二羧酸鹽或多羧酸鹽通常會(huì)增加產(chǎn)物的相對(duì)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、機(jī)械作用效果:攪拌可以提高PAM干粉的溶解速度，高強(qiáng)度攪拌速度會(huì)切斷聚丙烯酰胺的分子鏈，建議在線(xiàn)控制攪拌速度至60轉(zhuǎn)/分鐘，而不是使用高強(qiáng)度攪拌設(shè)備和高速輸送設(shè)備。
