噴霧干燥型聚合氯化鋁的產品質量很多時候關系到人們的生命健康，因此，生產噴霧干燥型聚合氯化鋁具有明確而嚴格的標準，可以保證人們的健康和安全。
滾筒式聚氯化鋁 鋁含量一般,水不溶物高,多用于污水處理.
板框式聚氯化鋁 鋁含量高， 水不溶物低. 用于污水處理和飲用處理.
噴霧干燥聚氯化鋁 鋁含量高， 水不溶物低，溶解速度快，用于飲用水及更高標準水處理.
PAC聚氯化鋁由于噴霧干燥穩定性好，適應水域寬，水解速度快，吸附能力強，形成礬花大，質密沉淀快，出水濁度低，脫水性能好等優點，在同樣水質的情況下，噴霧干燥聚氯化鋁投加量減少，尤其在水質不好的情況下，噴霧干燥產品投量與滾筒干燥聚氯化鋁相比，可減少一半，不僅減輕了工人的勞動強度，而更重要的是減少用戶的制水成本。除此之外，用噴霧干燥產品可保證安全性，減少水事故，對居民飲用水非常安全可靠。When treating drinking water, polyaluminium chloride with low content will have more impurities and water insolubles, so high content is required. Especially in papermaking, cosmetics production is to use high content.
Drinking water must be treated at drinking water level. Heavy metals are not detected at industrial level, and insoluble substances in water are also higher than drinking water. Generally speaking, drinking water level is related to human life and can not be used arbitrarily. It must be a real drinking water level. If industrial level is used for drinking water, there are many hidden dangers. And the purity is different, industrial use is 26-28%, drinking water is 30%.
And sewage treatment, the content requirements are not strict, low content is not too much, you can put more medicines can also achieve the desired effect.
Henan an Jia Jing Environmental Protection Technology Co., Ltd. specializes in the production of polyaluminium chloride, which is mainly divided into drinking water level and industrial grade. The production process is mainly divided into spray method and roller method.
Drum-type polyaluminium chloride is generally used for sewage treatment because of its high water insoluble content.
Plate-frame polyaluminium chloride has high content and low water insoluble. It is used for sewage treatment and drinking treatment.
Spray drying has high content of polyaluminum chloride, low insoluble substance and fast dissolution rate. It is used for drinking water and higher standard water treatment.
PAC polyaluminium chloride has the advantages of good stability in spray drying, wide adaptation to water area, fast hydrolysis speed and strong adsorption capacity. It has the advantages of large alum, high quality and fast sedimentation, low turbidity and good dewatering performance. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially when the water quality is not good, the product volume of spray drying is compared with that of drum drying polyaluminum chloride. It can be reduced by half, which not only reduces the labor intensity of workers, but also, more importantly, reduces the cost of water production for users. In addition, spray drying products can ensure safety and reduce water accidents, which is very safe and reliable for drinking water.
??在平常假如我們常常運用，能夠選擇干粉顆粒狀聚丙烯酰胺，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 polyacryla
mide 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，一般情況下干粉聚丙烯酰胺在干燥、陰涼的當地是寄存二年以上的，但假如配成溶液的話，它的寄存時刻就有限了，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的時后比較穩定，假如大于6.0的話，就會由于水解的原因而失效，水介質渙散型聚丙烯酰胺保質期為六個月。
