運用，能夠選擇干粉顆粒狀聚丙烯酰胺，The classific量低的聚合氯化液體，當溫度達到80 - 90℃時，1800萬的分子量會在2 - 4小時內(nèi)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(wěn)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(fā)劑、有機溶液和懸浮劑組成。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(chǎn)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(tǒng)的無機混凝劑的不同在：傳統(tǒng)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(zhì)經(jīng)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(yōu)異，能較好的去除水中各種有害重金屬離子。
銷售市場銷量的絮凝劑。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(yōu)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(wěn)過程。所謂失穩(wěn)，就是讓膠體粒子失去穩(wěn)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。現(xiàn)階段，由于它的諸多優(yōu)點，很受大家的歡迎。目前，我們還開發(fā)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(jù)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(chǎn)品質(zhì)量上還是在產(chǎn)品價格上，任何消費者都希望自己購買的產(chǎn)品是優(yōu)異的，質(zhì)量才是消費者選擇的一個重要標準。
n 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.由于它的固含量，一般情況下干粉聚丙烯酰胺在干燥、陰涼的當?shù)厥羌拇娑暌陨系模偃缗涑扇芤旱脑挘募拇鏁r刻就有限了，一般說，溶液濃度為0.1%的時候，非離子與陰離子聚丙烯酰胺溶液不會超過一周的時刻，陽離子聚丙烯酰胺溶液則不會超過一天，而且溶液的穩(wěn)定性與溶液的濃度有關，配的濃度越濃，例如3%——5%的溶液寄存時刻越長，但3%——5%的溶液不能直接去處理污水，這種在運用前需要稀釋，陽離子聚丙烯酰胺溶液PH值小于5.5的時后比較穩(wěn)定，假如大于6.0的話，就會由于水解的原因而失效，水介質(zhì)渙散型聚丙烯酰胺保質(zhì)期為六個月。
