Now for paper retention aids and drainage aid, paper mills mainly used inorganic rentention aids such as PAC, Alums and CaCl2, Natural retention aid such as starch, and synthetic polymer aids such as PAM Polyacrylamide.
In the field of papermaking, organic PAM polyacrylamide polymer is used to improve the quality of the paper, improving pulp dehydration performance, improve the fines and filler retention, reduce raw material consumption and pollution to the environment.
Normally in high speed and share rate condition, we suggest to use high molecular weight with low charge density PAM for fine fibers and fillers.
For retention in low speed and charge neutralization, we suggest to use low molecular weight with high charge density PAM as Retention Aids and Drainage Aids.
When use PAM for retention aids and drainage aids, we suggest to make PAM solution in two steps:
1, Dilute the PAM powder to 1%-2% solid content with clean water in high speed shear rate.
2, Dilute the solution again with plenty of clean water in a low speed share rate, then dose into the pulp.
Attention when making and storage the solution:
1, Finish using the diluted PAM solution in 24 hours
2, Avoid the diluted PAM solution in high speed shear rate.
As agent of retention and filtration, Cationic Polyacrylamide can increase the retention of the fiber and other additives, and accelerate filering and the dehydration, the fiber first layer retention can be increased 10%, then starch retention increased also, it is favorable for using the starch as the layer strengthening agent. Meantime, the profits is increased, also the fuction of filtration is improved, generally speaking, the high molecular weight polymer is more suitable for retention, and the low molecular weight polymer is suitation for filtration.
Recommend Dosage: 100-500g/ ton paper
