Anionic polyacrylamide
Anionic polyacrylamide can accelerate the settlement of particles in the suspension, with a very significant speed of accelerating solution, promote filtration and other effects. Anionic polyacrylamide is mainly used for flocculation settlement of various industrial wastewater, precipitation clarification treatment. Such as the wastewater treatment of paper and pulp wastewater, the wastewater treatment of the mineral and metal smelting process, the wastewater treatment of steel mills and stone processing plants.
Instructions of Anionic polyacrylamide :
1. When using, the anionic polyacrylamide is used as an aqueous solution of 0.1% concentration to use a neutralized water containing water.
2, when dissolved, the anionic polyacrylamide is uniformly sprinkled into the stirred water, and the stirring is controlled at 100 to 300 rpm. Adjustably heating (<60 ° C) can accelerate dissolution.
3. Adjust the pH of the treated liquid to make the anionic polyacrylamide to function (preferably the preferred pH value and the amount of the anionic polyacrylamide) by test.)
4, when the anionic polyacrylamide solution is added, the mixing of the treated liquid should be accelerated, and the flocculation is increased, and the stirring is slowed, and the growth and acceleration of the flip condensate.
Packaging and Storage of Anionic polyacrylamide:
The anionic polyacrylamide is packaged in 25kg lining coabble bag or paper-plastic composite bag, and can also be packaged according to user requirements.
The number of stacked layers must not exceed 20 layers, and the effective storage period is 2 years.
Store in a cool and ventilated dry place, pay attention to heat-resistant, moisture, prevent packaging damage, long-term termination will absorb the moisture.

Applications
Anionic polyacrylamide application range:
1. Anionic polyacrylamide is used in textile the printing and dyeing industry can serve as a fabric treatment of the slurry finishing agent and the protective layer of supplemented anti-wrinkle anti-mildew can reduce the tendon yarn Attractive rate. Polyacrylamide post-treatment agent can prevent static and flame retardant of fabrics. When used as a printing additive the polyacrylamide can make the product adhere to a large fault high and bright and can also be used as a bleached non-silicon polymer stabilizer.
2 anionic polyacrylamide is used as a flocculant: for suspended particles thicker high concentration particle belt matrix water pH is neutral or basic sewage since the anionic polyacrylamide molecular chain contains a quantity The resolved solid particles suspended in the water are adsorbed to form a large flocculation in the particle frame bridge. Therefore it accelerates the settlement of the particles in the suspension there is a very obvious acceleration of the clarification of the solution promoting the effect of filtration. This product is widely used in chemical industrial wastewater waste liquid treatment municipal sewage treatment. Since the water industry the purification Shenqing Washing Delta metallurgy Iron and Steel Industry Zinc Aluminum Plug Industry Electronic Industry etc.
3 the anionic polyacrylamide is used in the petroleum industry oil production drilling mud waste mud treatment preventing water from making it reducing the recovery and improving the recovery rate and three oil production are widely used.
4. Anionic polyacrylamide is used in papermaking industries one is to increase fillers pigments and other resolutions. To reduce the loss of raw materials and pollution to the environment; the second is to increase the strength of the paper (including dry strength and wet strength) in addition using PAM can also improve paper anti-tearness and porousness to improve visual and printing performance In food and tea packaging paper.
5 the anionic polyacrylamide in other industries such as the food industry used in sugar cane beet sugar production sugar juice clarification and syrup phosphorus float extraction. The fermentation of the enzyme preparation is clear and clearing the industry and is also used for the recovery of feed protein stable quality good performance. The recovered protein powder has increased and gains the survival rate of chicken and has no adverse effects synthetic resin coating and civil engineering grouting materials. Water building materials industry improve cement quality construction industrial adhesive flock repair and blocking agent soil improvement electroplating industry printing and dyeing industry etc.
6 the anionic polyacrylamide can be used as a clarified agent for mine wastewater and washing wastewater in the mining and coal production industry.
