Paper-making bentonite selected high-quality bentonite ore from the scientific processing. With fine particle size, high purity, good whiteness, cation exchange capacity, good water swelling, good suspension, suitable for a wide range of pH range. When the volume of water expansion increased several times to 30 times the specific surface area increased to 700-800 m2 / g. The main mineral composition montmorillonite micro-crystal surface with a negative charge, the edge of the end with a positive charge, combined with the cationic polymer can be used to achieve excellent retention filter effect, in addition to adsorption resin, control adhesives and so on. The main roles include:
⑴ improve the pulp in the small fibers and other filler retention rate, saving raw material costs, effectively reduce the pulp consumption.
⑵ improve the network case, the Department of vacuum and press the water filtration performance, purification of white water system to reduce the generation of sediment, antibacterial mildew, to avoid the formation of pulp, while reducing wet paper.
⑶ improve the paper pigment dispersion and uniformity, paper surface finish, paper evenness, paper strength and physical properties.
1.the scope of application
Bentonite Particles Retention Filtration System. Second, the use of methods
⑴ the use of the first in the pump or the entrance of the entrance to the cationic polymer, causing the paper filler and other components of the floc, these large flocs in the flow through the pump and pressure sieve when the high shear force is completely dispersed The
(2) Bentonite particles are added at the exit of the paper machine pressure sieve, which reconnects the dispersed floc by the charge-attracting action to form a uniform network-type microflocculant in the pulp. As a result of the network type flocculation Small and dense, so not only can improve the retention of paper retention filter performance, but also greatly improved the uniformity of the paper.
⑶ Before use, the first need to cationic polymer and bentonite were dissolved preparation, and then use the variable frequency screw pump to prepare the solution were controlled by the rotor flow meter added to the layers of pulp.
3.pay attention to matters
This product should be stored in a dry and cool place, prevent rain damp to avoid agglomeration, anti-exposure to avoid packaging damage.
4.packaging
Outside the woven bag lined with plastic film bag, net weight 40kg per pack.
