nonionic polyacrylamide ,FLOPAM FA920 SEP,Chinafloc N0310
FLOPAM FA920 SEP is a kind of nonionic polyacrylamide with very lower hydrolysis degree and very high molecular weight ,mainly used for water treatment and mineral processing and other application areas.Chinafloc N0310 is the equivalent model which can replace of FLOPAM FA920 SEP with good using result.
Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can adsorb solid particles suspended in water, make the particles bridge or through charge neutralization particles condense to form large flocculant. 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 settlement, precipitation and clarification treatment of various industrial wastewater. Such as paper and pulp wastewater treatment, mineral processing and metal smelting process of wastewater treatment, steel plant and stone processing plant wastewater treatment.
The physical properties of non-ionic polyacrylamide are mainly determined by the behavior in aqueous solution, due to the molecular chain containing amide or ionic genes, so its remarkable characteristics are 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 and so on are not sensitive, compatible with surfactants.
1, good water solubility, can also be completely dissolved in cold water. Details ()
2, add a small amount of non-ionic polyacrylamide, can be greatly flocculated effect. Generally only need to add 0.01~10ppm (0.01~10g/m3), can play a full role.
3, the use of non-ionic polyacrylamide and inorganic flocculants (polyferric sulfate, polyaluminum chloride, ferric salt, etc.), can show greater effect.
1, as a flocculant, mainly used in industrial solid-liquid separation process, including sedimentation, clarification, concentration and sludge dehydration and other processes, the main industry applications are: municipal 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 urban sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dehydration, through the positive charge group of the sludge in the negative charge of organic colloid electrical neutralization and polymer excellent bridging condensation function, to promote 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 aid, filter aid, can greatly improve the quality of paper, save costs, improve the production capacity of paper factory. Can be directly with inorganic salt ions, fibers and other organic polymer electrostatic bridge effect to enhance the physical strength of paper, reduce the loss of fibers or fillers, speed up the filter water, enhance, retention, filtration, can also be used for white water treatment, at the same time, in the deinking process can play an obvious flocculation effect.
3, fiber mud (asbestos-cement products) can make the formation of asbestos-cement products drainage improved, improve the strength of asbestos slab material; In insulating board, the binding ability of additives and fibers can be improved.
4, in 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, so as to remove turbidity, decolorization, in order to achieve discharge standards.
6. In phosphoric acid purification, it is helpful to the separation of gypsum in wet phosphoric acid process.
7, for the water treatment of river water plant flocculant.
