Welcome to WADE water treatment company.We have been in PAM this line over 20 years.Today we explain the paper mill paper machine polyacrylamide solution encountered problems.You will learn much from

Solution of Polyacrylamide in paper machine

1, must add the filtration equipment in the application, to prevent the gel group into the paper mill, paper machine, hanging and sticking cloth or paper produced cake. In the paper machine began to string water, we must first add polyacrylamide, so that the system exists polyacrylamide to prevent the dispersion of long fiber clusters, so that the production reached a normal state faster.
2, because can't add too much polyacrylamide, so it must be uniform, uniform, and scattered people. And join the speed can not be too fast, generally around 0.15 kg / min is appropriate. When the polyacrylamide is added into the water, a certain pressure of water must be injected into its adding point, which can be diluted and dissolved immediately after adding water to reach the best dissolving effect.
3, to add a certain amount of water until no stirring blade, start the blender, the water solution circulation and adding polyacrylamide, requirements of mixing blades should not have edges and corners, edges, or will cause the bad effect of hanging and shear polyacrylamide molecular chain and the solution concentration allowed, and weaken its dispersion effect.
4, polyacrylamide should now use is dissolved, because polyacrylamide aqueous solution will automatically hydrolysis in 20~48 hours, lose viscosity, and ultimately lose dispersion.
When the adding amount of polyacrylamide changes, slurry dehydration speed in paper machine will change. If the amount of polyacrylamide is adjusted too much, the dehydration will be too fast or too slow, which will affect the normal and stable production. Therefore, in the normal production of paper machine, do not arbitrarily adjust the amount of polyacrylamide.
