Cationic Polyacrylamide Flocculant Anionic Polymer For Metallurgy Industry
Cationic polyacrylamide (CPAM) is a copolymer composed of cationic units and non-ionic acrylamide units. There are ionizable positive charge groups (-CONH2) on the molecular chain, which can be ionized into polycations and small anions in water, can absorb and bridge suspended particles dispersed in the solution, and have a strong flocculation effect.
Cationic polyacrylamide is widely used in water treatment, metallurgy, papermaking, petroleum, chemical, textile, mineral processing and other fields. Used as a thickener, flocculant and drag reducer, with gelling, precipitation and strengthening effects. The molecular weight of CPAM is generally lower than that of NPAM and APAM, and is especially suitable for the dehydration treatment of industrial sludge such as municipal sewage, municipal sludge, and paper sludge.

The cationicity is the charge density of the CPAM molecular chain. Cationic degree is one of the determinants of flocculation effect. If the ions are too low, the flocculation is little or no effect. If the ions are too high, the sludge flocs will be repelled due to the excessive charge. Therefore, for the sludge to be dewatered, flocculants with different ionic properties can be screened through a small test, and the best and appropriate polyacrylamide can be selected, which can achieve a good flocculation effect and minimize the amount of chemical agents added. cost. Key points of ion selection:
(1) The size of the flocs: too small flocs will affect the drainage speed, too large flocs will combine more water and reduce the degree of mud cake. The size of the flocs can be adjusted by selecting the molecular weight of polyacrylamide.
(2) Floc strength (moisture content): The floc should remain stable under shearing action without breaking. Increasing the molecular weight of polyacrylamide or choosing a suitable molecular structure helps to improve the stability of flocculation.
