Polyacrylamide / The cationic polyacrylamide (Zetag 7645) can be replaced by a CHINAFLOC C0510
The cationic polyacrylamide (Zetag 7645) can be replaced by a CHINAFLOC C0510
Zetag 7645 is a cationic polyacrylamide with low ionic degree and medium molecular weight, which can be widely used in water treatment. CHINALFOC C0510 can be completely replaced, with good application effect.
Cationic polyacrylamide is a linear polymer composed of cationic monomer and acrylamide copolymerization. Because cationic polyacrylamide has a variety of active groups, it can form hydrogen bonds with many substances affinity and adsorption. Because of its own positive charge, it mainly deals with substances with negative charge, so it has turbidity removal, adsorption, adhesion and other functions.
Cationic polyacrylamide is mainly suitable for dyeing, papermaking, food, construction, metallurgy, mineral processing, coal, aquatic processing and fermentation industries with higher organic content of wastewater treatment, especially suitable for municipal sewage, sludge, papermaking sludge and other industrial sludge dewatering treatment agents.
[Product features] :
1, cationic polyacrylamide water solubility is good, even in cold water can be completely dissolved.
2, add a small amount of cationic polyacrylamide, can have obvious flocculation effect. Generally, only 0.01~10ppm (0.01~10g/m3) is needed to give full play to the effect.
3, the use of cationic polyacrylamide and inorganic flocculant (polyferric sulfate, polyaluminum chloride, aluminum salt or iron salt, etc.), can show a greater effect.
[Scope of application] :
1, used for sludge dewatering according to the nature of sludge can be selected cationic polyacrylamide corresponding model, can effectively in the sludge into the pressure filter before sludge dewatering, dehydration, flocculation, non-stick filter cloth, pressure filter is not loose, flow mud cake thick, dehydration efficiency is high, mud cake moisture content is below 80%.
2, as flocculating agent, mainly used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dewatering technology, application of the main industries are: urban sewage treatment, paper industry, food processing, petrochemical industry, metallurgical industry, processing industry, dyeing industry and sugar industry and all kinds of industrial wastewater treatment. Used in urban sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dewatering by its organic colloid electrical group of sludge negative charge neutralization and excellent polymer bridging coagulation function, prompting colloid particles gathered into large pieces of floc, separated from the slurry. The effect is obvious and the dosage is small.
3, cationic polyacrylamide used in oil field additives, such as clay swelling agent, oil field acidification with thickening agent.
4, cationic polyacrylamide used in paper industry, one is to improve the retention rate of filler, pigment, etc. To reduce the loss of raw materials and environmental pollution; Two is to improve the strength of the paper (including dry strength and wet strength), in addition, the use of PAM can also improve the tear resistance and porosity of the paper, to improve the visual and printing performance, but also used in food and tea wrapping paper.
5, cationic polyacrylamide used for the treatment of river water as water source flocculant, less dosage, good effect, low cost, especially and inorganic flocculant compound use effect is better, it will become the treatment of the Yangtze River, the Yellow River and other watershed water plant efficient flocculant.
6, used for textile, printing and dyeing industry. Cationic polyacrylamide can be used as sizing agent and finishing agent for fabric treatment, as well as a protective layer that can produce smoothness, crease resistance and mildew resistance. With its high moisture absorption, it can reduce the breaking tension of spinning yarn. Polyacrylamide as post-treatment agent can prevent static electricity and flame retardant fabric. Used as printing and dyeing auxiliaries, polyacrylamide can make the product adhesion fastness, high brightness, but also as a bleaching non - silicon polymer stabilizer.
1, when used, dissolved granular cationic polyacrylamide water should be clean (such as tap water), not sewage. Normal temperature water, water temperature is lower than 5℃ when the dissolution is very slow, water temperature will increase the dissolution rate, but more than 40℃ will accelerate the degradation of PAM, affecting the use effect. Generally tap water is suitable for preparing polymer solutions. Water with strong acid, alkali and high salt content is not suitable for preparation.
2, dissolution, the cationic polyacrylamide evenly scattered into the stirring water, stirring speed control at 100~300rpm. Proper heating (< 60°C) can accelerate dissolution.
3, adjust the pH value of the treated liquid, so that the cationic polyacrylamide fully play its role (through the test to choose the appropriate pH value and dosage.)
4, adding cationic polyacrylamide solution, should be accelerated with the mixing of the treated liquid, the emergence of flocculation, slow down the stirring speed, to facilitate the growth of flocculation and accelerated settlement.
[Packaging and storage] :
Cationic polyacrylamide adopts 25kg paper plastic composite bag packaging, can also be packed according to user requirements.
When storing, pay attention to prevent heat and moisture to prevent package damage. Dry powder products will absorb moisture and agglomerate when exposed for a long time.
Stacking layers shall not exceed 20 layers, effective storage life is 2 years, prepared solution (1-3 days).
