2、溫度影響: 0.1液體，當溫度達到80 - 90℃時，1800萬的分子量會在2 - 4小時內降解到500萬左右，并且降解會隨著溫度的升高而變得越來越快。在25℃的室溫下性能穩定。
懸浮在有機溶劑中的單體水溶液與小液珠的聚合稱為懸浮聚合，也稱為珠聚合。懸浮聚合物主要由單體、引發劑、有機溶液和懸浮劑組成。引發劑溶解在單體水溶液中。分散劑也被稱為懸浮劑。其功能是在攪拌下將單體水溶液分散成小液珠，并將其懸浮在有機溶劑中，以防止聚合顆粒在聚合過程中相互粘附。產品的粒度一般為100-2000 μ m
Storage time: With the increase of storag胺稱為聚氯化鋁或者絮凝劑等等。聚合氯化鋁和傳統的無機混凝劑的不同在：傳統無機混凝劑是低分子結晶鹽，聚合氯化鋁是由各種不同的化學物質經高溫高壓聚合而成，絮凝沉淀快速，對管道設備腐蝕性小，凈水效果優異，能較好的去除水中各種有害重金屬離子。
銷售市場銷的絮凝劑。聚合氯化鋁具有絮凝體生成快、沉降性能好、水中堿度消耗低的優點，尤其對水溫、酸堿度、濁度和有機物含量的變化適應性強。事實上，聚合氯化鋁的整個絮凝過程也是一個失穩過程。所謂失穩，就是讓膠體粒子失去穩定性的過程。原本均勻分散在液體中的固體顆粒結合成大顆粒，然后沉淀出來，超過了凈水的目的。影響其有效性的因素也很多，如溶液的PH值、溫度、攪拌速度、攪拌時間、水體特性等?，F階段，由于它的諸多優點，很受大家的歡迎。目前，我們還開發了復合無機高分子絮凝劑。這類絮凝劑的絮凝特性和沉降性能會在聚合氯化鋁的水平上更進一步，相信未來會占據很大的銷售市場！
在處理污水時怎么樣選擇適用的聚合氯化鋁，在處理污水通常使用聚合氯化鋁，無論是在產品質量上還是在產品價格上，任何消費者都希望自己購買的產品是優異的，質量才是消費者選擇的一個重要標準。
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較低，其通常作為珠粒懸浮在有機相中。因此，所用的有機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；攪拌強度也低于乳液聚合。懸浮聚合得到的產品為顆粒狀，使用方便。
3、在懸浮聚合溶液中，在懸浮劑如Span60、無機酰胺、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定的懸浮液以引發聚合。懸浮聚合結束后，共沸脫水、分離、干燥，得到珠狀或粉末狀產品。在聚合過程中加入無機鹽氯化鈉、納米3或Na2NO3可以調節體系的表面張力，提高懸浮穩定性，但對聚合過程影響不大。然而，加入少量的單羧酸鹽、二羧酸鹽或多羧酸鹽通常會增加產物的相對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、機械作用效果:攪拌可以提高PAM干粉的溶解速度，高強度攪拌速度會切斷聚丙烯酰胺的分子鏈，建議在線控制攪拌速度至60轉/分鐘，而不是使用高強度攪拌設備和高速輸送設備。
