Cationic polyacrylamide (CPAM) is a linear polymer compound. Because it has a variety of active groups, it can affinity with many substances and adsorb to form hydrogen bonds. It is mainly a colloidal negatively charged colloid with functions such as turbidity removal, decolorization, adsorption and adhesion. It is suitable for organic colloidal content in dyeing, paper making, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic product processing and fermentation. High wastewater treatment, especially suitable for dewatering of municipal sewage, municipal sludge, paper sludge and other industrial sludge.
Cationic polyacrylamide function
Because cationic polyacrylamide has the following effects:
1. Clarify the purification effect;
2. Settlement promotion;
3. Filtration promotion;
4. Thickening effect and other effects.
Therefore, it can fully meet the requirements in waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, paper making and the like.
5, PAM has a unique decolorization ability, mainly used in the decolorization treatment of high chroma wastewater in dye factory, the applicable dye varieties are active, acidic and disperse dyes.
6, can also be used for textile, printing and dyeing, ink and other industrial wastewater treatment.
7. The decolorization rate of this product to wastewater is over 95%, and the removal rate of COD is between 40-70%.
Characteristics of cationic polyacrylamide
1. It has good water solubility and can be completely dissolved in cold water.
2. Add a small amount of cationic polyacrylamide product, which can be greatly flocculated. Generally, only 0.01~10ppm (0.01~10g/m3) can be added to fully function.
3. Simultaneous use of cationic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, iron salts, etc.) can show greater effects.

Use of cationic polyacrylamide
1. For sludge dewatering According to the nature of the sludge, the corresponding model of this product can be selected, which can effectively carry out sludge dewatering before the sludge enters the pressure filtration. When dewatering, the floc is large, the non-stick filter cloth is not used, and the filter is not Dispersed, the mud cake is thicker, the dewatering efficiency is high, and the moisture content of the mud cake is below 80%.
2. For the treatment of domestic sewage and organic wastewater, the product is positive in the compound or alkaline medium, so that the sewage with suspended charge in the sewage is flocculated and precipitated, and the clarification is very effective. Such as the production of food alcohol wastewater, papermaking wastewater, municipal wastewater treatment plant wastewater, beer wastewater, MSG wastewater, sugar wastewater, high organic content wastewater, feed wastewater, textile printing and dyeing wastewater, etc., with cationic polyacrylamide than with anions, The effect of nonionic polyacrylamide or inorganic salts is several times or several times higher, because such wastewater is generally negatively charged.
3. The flocculant used for the treatment of tap water with river water as the water source, the dosage is small, the effect is good, the cost is low, especially the combination with inorganic flocculant is better, it will become the tap water for treating the Yangtze River, the Yellow River and other river basins. The factory's high-efficiency flocculant.
4. Reinforcer for papermaking and other additives. Improve the retention rate of fillers, pigments, etc., and the strength of paper.
5, used in oilfield chemistry additives, such as clay anti-swelling agent, thickener for oil field acidification.
6, for textile sizing agent, slurry performance is stable, less pulp, low fabric breakage rate, smooth surface.
Method of use, packaging and storage
1. Granular polyacrylamide cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution is used to treat the sewage.
2. The water that dissolves the granular polymer should be clean (such as tap water). It can be used at room temperature and generally does not require heating. Water temperatures below 5 ° C are very slow to dissolve. The water temperature increases the dissolution rate, but above 40 °C, the polymer will accelerate degradation and affect the use effect. Generally tap water is suitable for formulating polymer solutions. Strong acid, strong base, high salt water is not suitable for formulation.
3. The choice of polymer solution concentration is recommended to be 0.1%-0.3%, that is, 1g-3g polyacrylamide is added to 1 liter of water.
4, this product is non-toxic, pay attention to moisture, rain, avoid sun exposure. Storage period: 2 years, 25kg paper bag (with plastic bag outside the plastic bag).
