Application:
Mining industry
Polyacrylamide can be widely used in the mining of gold,silver,copper,aluminum,lead,zinc,ect.Water is much needful needed during the process,effectively separating the solid mineral from the water or solution.Polyacrylamide is especially used as flocculant or the agent of filtration during the process, not only promoting the solid sink down rapidly and improving the effect of filtration,but also enhancing the separation sffect and production efficiency.Meanwhile,it can reduce the loss of the tailings and cost.
Coal washing industry
After the coal is exploited,it is usually mixed with other kinds of waste.Firstly,,they are separated according to their different gravity in water, the coal is suspended, then the waste get down.
In the following process,by using flotation agent, the fine coal particle and the waste are further separated,fine coal floats and the waste is down.
Then the fine coal is refined from the waste by sedimentation,filtration or centrifugation.Polyacrylamide is used in the process of sedimentation,promoting the separation of solid and liquid,and then the clean water is recycled back from the overflow by the thickener,the fine coal particle is generated after filtration and centrifugation.Polyacrylamide is used in the process of sedimentation, promoting the separation of solid and liquid,and then the clean water is recycled back from the overflow by the thickener, the fine coal particle is generated after filtration and centrifugation. polyacrylamide is used again in the process of filtration and centrifugation to improve the efficiency of separation.
Advantage:
1. Easy to dissolve.
2. It is with high performance and it can adapt to a variety of conditions.
3. The dose is small and high efficiency.
4. High molecular.
5. High purity.
Application Method:
1. The product should be prepared for the water solution of 0.1% as concentration. It is better to use neutral and desalted water.
2. The product should be scattered evenly in the stirring water, and the dissolving can be accelerated by warming the water (below 60 °C).
3. The most economical dosage can be determined based on a preliminary test. The pH value of the water to be treated should be adjusted before the treatment.
Package and Storage:
25KG white nylon bags/woven/paper bags with pallets;
Keep in dry place,avoid heat & humidity; valid storage time: 2 years.
