Why polyacrylamide flocculant has broad space for development


Polyacrylamide flocculant wide use, the amount of large , broad space for development . Price of thousands to several million one ton range. As the saying goes a sub-price goods, in particular about the price , but also have to pay attention to product quality. Now polyacrylamide market is chaotic , Le Bang water experts have warned customers friends , get the best time to buy amide done a small test sample and then decide the next single.
The question: Which of alkaline wastewater with polyacrylamide ?
PH value of the different types of wastewater applications polyacrylamide different ranges of alkaline wastewater treatment what polyacrylamide use? Le Bang alkaline waste water treatment expert advice , you can choose the best product in the applicable anionic polyacrylamide and cationic polyacrylamide , and then to determine the most suitable products through small scale .
Question two : PH value is too large to use what polyacrylamide ?
Selection of different types of wastewater with PH values also appear very different ! PH value is too large alkaline environment , generally used anionic polyacrylamide APAM; PH value is too small acidic environment , we can use cationic polyacrylamide ;
Question three: preparation of an aqueous solution of polyacrylamide require much concentration ?
General preparation of the anionic polyacrylamide thousandth , which is an aqueous solution of about 0.1% ; cationic polyacrylamide can be formulated as 0.1% to 0.4 %.
Question 4: preparation of a good solution should be stirred for how long?
PAM should generally be formulated stirring continued for 30 minutes or more, generally about 50 minutes can be used in some PAM difficult to dissolve in the winter , it is recommended to extend the mixing time to ensure that it fully dissolved ; reconstituted solution should be used as soon as polyacrylamide , anionic generally not more than 36 hours , hydrolyzed cationic easily dissolved , should be within 24 hours .
