FAQ

Anionic polyacrylamide application involves mining, ore dressing and metallurgy. Through the use of polyacrylamide, can promote the effective solid matter soon settlement, or speed up the fine objects of concentrated, to improve the solid-liquid separation effect, reduce the tailings loss and environmental pollution, reduce production cost.

Oil production is separated into three phases: primary, secondary and tertiary, which is also known as Enhanced Oil Recovery (EOR). Primary oil recovery is limited to hydrocarbons that naturally rise to the surface, or those that use artificial lift devices, such as pump jacks. Secondary recovery employs water and gas injection, displacing the oil and driving it to the surface. According to the US Department of Energy, utilizing these two methods of production can leave up to 75% of the oil in the well.

Anionic polyacrylamide is suitable for inorganic suspended solids with  higher concentration and positive charge, and the suspension particles is coarse (0.01-1mm), pH value is neutral or alkaline solution.

Cationic polyacrylamide applicable to the suspended matter with negative charge, containing organic substances.

non-ionic polyacrylamide applicable to mixed  solution with organic and inorganic suspended substance ,the ph value is  acidic solution or neutral.

Amphoteric polyacrylamide applicable to wastewater of the  properties of suspended substance and pH  value is always changeable..

Anionic polyacrylamide APAM applicable to the more suspended particles , high concentration, particle with positive charge, water pH value is neutral or alkaline water, iron and steel plant wastewater, electroplating wastewater, wastewater metallurgy, coal washing wastewater and sewage treatment, the best effect.

Method and principle

Weigh a certain amount of sample and put it in the tea bag. After the tea bag was put into the liquid for absorption for 30min, it was suspended for 10min to drain the excess liquid before weighing calculation to determine the water absorption ratio.

Method and principle

The SAP sample was rapidly added to a solution of 0.9%NaCl in a known volume that was being stirred. The SAP sample absorbed the salt solution and began to form a gel. Record the time from the time SAP was added to the time it took for the liquid gel to form, the whirlpool generated by stirring to disappear, and finally the gel surface became smooth.

• Flocculation ability

• Without alkali and other additives, PH broad in scope, have little influence in temperature, PH value.

• Ease of use

• Reduce effectively seston in acid aluminum and improve settling tank capacity.

• Improve clarity and the quality of the overflow, low liquid-solid ratio, prevent red mud inflation.
