What is the difference between ionicity and molecular weight of cationic polyacrylamide?

Both suppliers and purchasers need to be exposed to product specifications as water purification materials for the water treatment industry, where the parameter that you generally need to know about Cationic Polyacrylamide(Cpam) is the ionicity.Cationic Polyacrylamide(Cpam) has an ionicity of 12% to 60%, and a molecular weight of millions and tens of millions. What is the difference between the two types of cationic polyacrylamide(CPAM) with different index levels?

     First of all, explain the concept of molecular weight and ionicity:

   Ionicity] Ionicity is actually the charge density, ionicity determines the price of the product, ionicity also determines the tightness of the floc, but choose what ionicity of the product is appropriate, or have to do the selection test, that is, a small test, and then the pilot on the machine, and finally to determine the best agent. The ionicity of cation refers to the number of cationic ions contained in PAM, the molecular weight is generally around 800-1200. The higher the ionicity, the bigger and tighter the effect of the impurity ready group in the sewage, the ionicity of cation mainly depends on the height of the desludging equipment.

Molecular weight] Molecular weight is the length of molecular chain, the molecular weight is not necessarily good, small molecular weight is not necessarily bad, the key must be combined with the dewatering equipment and sludge properties. For example, for belt machine, the molecular weight can not be too high, if the molecular weight is very high, it may lead to the clogging of filter cloth, affecting the dewatering effect; and then for example, for centrifuge, the molecular weight *ment should be a little bit higher, and it is *d that the flocs can be as much as possible to resist the shear, so it is necessary to choose the product with relatively high molecular weight.

Cation mainly depends on the ionic degree rather than molecular weight, as for the application field, it is mainly the equipment and mud property.

Cation is mainly for urban sewage and sewage with negative charge in the sewage, when the cation one-thousandth of the water into the water can produce parcel sewage impurities to play a role in bridging precipitation, which is often referred to as sewage desludging, we can see the impurities in the sewage will be put into the water very quickly precipitate to let the water and the impurities to separate apart, so that the later desludging equipment to run.

In different applications, polyacrylamide series products performance is different, need to be adjusted according to the product characteristics and application environment, through the experiment to find a most economical products and determine its ratio and dosage.
