Green clean environment-friendly anionic polyacrylamide

Lujie anionic polyacrylamide is a water-soluble linear polymer synthesized with a high degree of polymerization. Although the anionic polyacrylamide decreases the surface tension of water very little, there are active groups in the molecule, which can change the state of the interface after being adsorbed on the interface. Its amide group (-CONH2) can bind to many substances and form hydrogen bonds, which can make it bridge between adsorbed particles, connect several or even dozens of particles together, and promote colloidal particles Aggregate into large flocs, accelerate the sedimentation of particles in suspension, accelerate solution clarification, and promote filtration.

Lujie anionic polyacrylamide product use
A. Industrial wastewater treatment. Especially for wastewater with a neutral pH or alkaline pH, large suspended particles in water, high concentration, and positive charge, such as sewage treatment in iron and steel plants, electroplating plants, metallurgical plants, and coal washing plants, the effect is very significant.
B. Drinking water treatment. The use of this product to treat tap water with high sand content and turbidity has the advantages of low dosage, low cost and no secondary pollution.
C. Papermaking additives. It can be used as dispersant for long fiber papermaking, wet and dry enhancer, retention aid and filter aid, and flocculant for papermaking wastewater.

Green Jie Anionic Polyacrylamide Instructions
A. During use, the operation of effectively dispersing this product in water is extremely important, otherwise it will cause agglomeration of polyacrylamide and produce "fish eyes", and the dissolution time increases.
B. When the product is dissolved, water with relatively low hardness is required. It is best to avoid using materials that easily affect water quality in the dissolving tank.
C. The use of warm water can accelerate the dissolution rate, but the temperature is too high, it will lead to thermal degradation of molecular chains, viscosity will be affected, the general water temperature can not exceed 50 ℃.
D. Stirring can help dissolve, but too strong stirring will cause the polymer long chain to break and degrade. It is best to use a ship-type propeller type agitator with a speed of 200-500rpm.
E. Under normal circumstances, first dissolve polyacrylamide to make 0.05% -0.5% for use.
F. The optimal dosage of polyacrylamide varies according to the application.

Precautions for Lujie Anionic Polyacrylamide
Dry powder products are easy to absorb moisture, pay attention to moisture and moisture during storage. It should be stored in a ventilated and dry warehouse, protected from moisture and rain, and should not be exposed to the air or sunlight.
