- Nov 25, 2016 -

PAC daily use how it goes? now we take a look at it, on the PAC to learn in this area, to help users better understand and can help users to better prepare the following aspects of the detailed requirements!

PAM before use can be prepared into a solution of 0.05%-0.3%, need attention in the preparation:

1 do not speed or long time mixing, agitation speed should be less than 200 revolutions per second. Open, mix well, PAM spread the solid into water.

2 avoid contact with vessel and preparation should be in pottery, concrete, galvanized steel, aluminum, or plastic containers. No pollution or high hardness water to dissolve.

3 dissolution equipment is generally rounded, no dead ends.

41 completed, if the suspension is of high density and high viscosity shall be diluted solution called about 0.01%, it's easier to mix and achieve better results.

5 melting temperature should not be higher than 60 degrees.

6 of polyacrylamide solution with best now, and cations should be used within 1 day, anion is best used within 2 days.

7 dissolution well flocculant with screw pump to shear pump, diaphragm pump, centrifugal pump should not be used.

8 when used in wastewater with inorganic coagulants should join inorganic coagulants, after about 1 minute, then add polyacrylamide products, order cannot be reversed, so as not to reduce the results.
