Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can adsorb the solid particles suspended in water, bridge the particles or condense the particles through charge neutralization to form large flocculates. Therefore, it can accelerate the settlement of particles in the suspension, has a very obvious acceleration of solution clarification, promote filtration and other effects. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewater. Such as paper and pulp wastewater treatment, mineral processing and metal smelting process wastewater treatment, steel plant and stone processing plant wastewater treatment.
Chemical property
The physical properties of non-ionic polyacrylamide are mainly determined by its behavior in aqueous solution, due to the molecular chain containing amide or ionic genes, it is significantly characterized by high hydrophilicity, can be dissolved in water in various ratios, polyacrylamide aqueous solution has a good tolerance for electrolytes, such as chlorinated amine, sodium sulfate, etc., are not sensitive to surfactants are also compatible.
Application field
1, as a flocculant, mainly used in industrial solid-liquid separation process, including sedimentation, clarification, concentration and sludge dewatering and other processes, the main industries are: urban sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgy industry, mineral processing industry, dyeing industry and sugar industry and various industrial wastewater treatment. Used in municipal sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dehydration, through the positive charge group contained in the sludge of negative charge organic colloid electrical neutralization and polymer excellent bridging condensation function, to promote the colloidal particles gathered into large flocculent, separated from its suspension. The effect is obvious and the dosage is small.
2, in the paper industry can be used as paper dry strength agent, retention agent, filter aid, can greatly improve the quality of paper, save costs, improve the production capacity of paper mills. It can directly act as an electrostatic bridge with inorganic salt ions, fibers and other organic polymers to enhance the physical strength of paper, reduce the loss of fibers or fillers, speed up water filtration, enhance, help retain, help filter, and can also be used for the treatment of white water, at the same time, it can play an obvious flocculation effect in the deinking process.
3, fiber mud (asbestos-cement products) can improve the drainage of formed asbestos-cement products, so that the strength of asbestos slab material; In the insulating board, the binding ability of additives and fibers can be improved.
4, in the mining, coal preparation industry can be used as mine wastewater, coal washing wastewater clarifying agent.
5, can be used for dyeing wastewater, leather wastewater, oily wastewater treatment, to remove turbidity, decolorization, in order to meet the discharge standards.
6, in phosphoric acid purification, contribute to the separation of gypsum in the wet phosphoric acid process.
7. Flocculant for water treatment of water treatment plants with river water sources.
Usage method
1, when used, it is matched into an aqueous solution of 0.1% concentration, and it is appropriate to use neutral water without salt debris.
2. When dissolved, the non-ionic polyacrylamide is evenly sprinkled into the stirred water, and the stirring speed is controlled at 100~300rpm. Proper heating (< 60°C) can accelerate the dissolution.
3, adjust the PH value of the treated liquid, so that non-ionic polyacrylamide fully play a role (through the test to select the best PH value and the amount of non-ionic polyacrylamide.)
4, when adding non-ionic polyacrylamide solution, should accelerate the mixing with the treated liquid, after the emergence of flocculant, slow down the stirring, to facilitate the growth of flocculant and accelerate settlement.
FAQ
What are the applications of Polyacrylamide?
Polyacrylamide has a wide range of applications in various fields. In terms of water treatment, Polyacrylamide can be used for wastewater treatment, drinking water purification, and industrial wastewater treatment, among others. Additionally, it can be used in mining, oilfield development, textiles, papermaking, soil stabilization, and construction materials.
How to choose the right Polyacrylamide product?
The technical indexes of polyacrylamide are generally molecular weight, hydrolysis degree, ionic degree, viscosity, residual monomer content, etc., so the quality of PAM can be judged from these indexes.Understand the source of sludge,and dehydration equipment also importment for us to choose the right polyacrylamide.
Is polyacrylamide safe for skin?
Residual levels of acrylamide in Polyacrylamide can range from <. 01% to 0.1%, although representative levels were reported at 0.02% to 0.03%. Because of the large sizes of Polyacrylamide polymers, they do not penetrate the skin. Polyacrylamide itself is not significantly toxic.
What is the difference of acrylamide and polyacrylamide?
the key difference between acrylamide and polyacrylamides is that polyacrylamide is a polymer and acrylamide is the sub unit used to produce polyacrylamide molecules. Therefore, acrylamide is considered as a small molecule whereas polyacrylamide has a high molecular weight.
