1) for sludge dewatering according to the nature of the sludge can choose the corresponding model of the product, can be effectively in the sludge into the filter before the sludge dehydration, dehydration, the production of large flocculation, non-stick filter cloth, pressure filtering, mud cake thicker, high dehydration efficiency, mud cake moisture content under 80%. 2) for the treatment of domestic sewage and organic wastewater, this product in the distribution or alkaline medium are presented positive electricity, so that the sewage suspended particles with a negative charge of the sewage flocculation sedimentation, clarification is very effective. such as the production of food alcohol waste water, papermaking wastewater, Municipal wastewater Treatment plant wastewater, beer wastewater, monosodium glutamate plant wastewater, sugar wastewater, high organic content of wastewater, feed wastewater, textile printing and dyeing wastewater, with cationic polyacrylamide than with anionic, nonionic polyacrylamide or inorganic salts effect is several times or dozens of times times higher,
Because this kind of waste water generally has the yin charge.
3) used for water as water source of water treatment flocculant, less dosage, good effect, low cost, especially with the inorganic flocculant composite use effect is better, it will become the Yangtze River, the Yellow River and other watersheds of the water plant of high-efficiency flocculant. 4) reinforcing agent for papermaking and other additives.
Improve the retention rate of fillers, pigments, paper strength.
5) used in oilfield classics auxiliaries, such as clay anti-swelling agent, oilfield acidizing thickening agent.
6) used in textile sizing agent, slurry performance stability, low slurry, fabric breakage rate, cloth smooth. Packaging and storage of this product non-toxic, pay attention to moisture, prevent rain, avoid sun exposure.
Storage period: 2 years, 25kg paper bag (lined with plastic bags outside of the paste-plastic kraft bag). Polyacrylamide can be applied to a variety of sewage treatment (for domestic sewage treatment using polyacrylamide is generally divided into two processes, one is the polymer electrolyte and the surface of the particle charge neutralization, and the second is the long chain of polymer electrolyte and the particle bridge formation of flocculation. The main purpose of flocculation is to make the small suspended particles and colloidal particles in the sludge form a larger flocculation group by adding polyacrylamide. With the increase of flocculation, the sedimentation velocity increases gradually. In order to better through the pressure filter press mud, and then achieve the requirements of environmental protection treatment, dry mud Sinotrans incineration treatment. Pam is a molecular weight from millions of to tens of millions of of the polymer water-soluble organic polymers, the formation of a larger floc between the particles and the resulting large surface adsorption effect. The current domestic polyacrylamide representative polymer polyacrylamide has: nonionic polyacrylamide (abbreviated NPAM, molecular weight 80.015 billion), Anionic polyacrylamide (abbreviated APAM, molecular weight 80.02 billion), Cationic polyacrylamide (abbreviated CPAM, Molecular weight 80.012 billion, ionic degree 10%-80%). The dosage is generally one out of 10,000 to two out of 10,000 of the amount of waste water.
Thus, it is mainly formed by artificial synthesis. Preparation: Firstly, a compound initiator system consisting of redox reaction system, azo compound and auxiliary initiator was used to synthesize cationic polyacrylamide (CPAM) with acrylamide (AM) and propylene amide ethyl three methyl ammonium chloride (or DMC,DMAAC) as raw material by copolymerization of free radicals in aqueous solution. In the reactor to add a certain amount of acrylamide, propylene amide ethyl three methyl ammonium chloride, urea and deionized water, stir evenly, with 2mol/l H2SO4 adjust ph to the required value, N2 bubble 30min, add a certain amount of (NH4) 2s2o8, Ch3nao3s.2h2o and azo compounds induce polymerization reaction, when the reaction fluid viscous, stop through N2, continue to respond to 2h after the white transparent, the colloid in 60C drying to constant weight, crushing, that is, cationic polyacrylamide flocculant.
