When it comes to polyacrylamide (PAM), the first thing many customers consider is price. Since there are many models of PAM according to different molecular weights and ionic degrees, the prices are naturally different. Among the many models, cationic polyacrylamide (CPAM) is priced higher than all types of polyacrylamide (PAM) of the same specification. So why is the price of cationic polyacrylamide (CPAM) high? In fact, the reason for the price increase of anything is inseparable from production costs and production processes. The following Henan Laixing Water Purification will give you a detailed answer to the reasons for the high price of cationic polyacrylamide (CPAM).
In terms of use effect, cationic polyacrylamide (CPAM) has a good effect not only in sewage treatment, but also in sludge dewatering. Cationic polyacrylamide (CPAM) is used for sludge dewatering, the flocculent is large, the filter cloth is non-stick, the filter is not dispersed during filter pressing, the mud cake is thick, the dehydration efficiency is high, and the moisture content of the mud cake is less than 80%. As a flocculant, cationic polyacrylamide (CPAM) is used in the main industries of urban sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgical industry, mineral processing industry, dyeing industry and sugar industry, and wastewater treatment in various industries. Through the electrical neutralization of negative charge organocolloids in sludge and the excellent cross-linking and cohesion function of polymers, the colloidal particles are promoted to aggregate into large flocculents and be separated from their suspensions. It has the characteristics of obvious effect and small dosage.
In addition, the high price of cationic polyacrylamide (CPAM) is also closely related to the production cost. Because the cationic monomer used for production is more expensive than acrylamide (AM) monomer, the cost of producing cationic polyacrylamide (CPAM) will be higher than that of other types of productsThe price of nonionic polyacrylamide (NPAM) is second, and the price of anionic polyacrylamide (HPAM) is lower. Some customers think that cationic polyacrylamide (CPAM) is expensive and the use effect will definitely be very good, in fact, this is wrong, the type, molecular weight, dosage of polyacrylamide (PAM) have corresponding peaks, after reaching the peak, the use effect will not rise but will decrease. Therefore, it is necessary to choose the appropriate product type according to the water quality and equipment conditions on site, not the more expensive the better.
