intro:
In recent years, with the rapid development of papermaking
technology, the Department of wetlands one of the main chemicals
Retention and filter technology to a new and higher demands.
Retention single filterand ordinary dual filter retention of the
slurry are very sensitive to the chemical properties of a single
polymer through the role of the bridge was filled with polymer,
after high shear stress can damage effective reunion. And general
dual Drainage and Retention can flocculating agent despite a high
shear force of the flocculation, as a bridging role in the
formation of Flocculation only expected to improve paper machine
network in the Department of gravity dehydration on the sheet of
vacuum dehydration, dehydration and squeezing good for the forming
of paper instead of negative. In order to meet the needs of
high-speed machine, I introduced both at home and abroad advanced
and mature Retention bentonite particulate filter system.
The Company bentonite particulate filter system
Retention by the cationic polymer-modified bentonite and inorganic
particles formed. Its role is: to join the use of cationic
polymers, paper materials from components Flocculation Then-pump,
high shear rotor screen role will be filled with large pieces of
paper material broken into small pieces Xu, filled with small
pieces subsequently joined by the anion bentonite particles
connected into the network-type uniform of the flocculation.
Accordingly, its retention and drainage effect was very good in the
floc smaller, the bridge can be achieved with the same degree of
Flocculation and thus can improve the evenness of paper, and filled
with pieces of small by between inorganic Bentonite the role of
particulate connected to the pool together, the floc formation of
small and dense, can be very good material to improve the treatment
of paper, a paper permeability better.
Bentonite particles dual Retention System
major role in the Paper Industry：
1、 perfect sheet forming and evenness
2、 one-way fiber increase retention.
3、 greatly improved filtration properties
of paper. Progressive makes drying of the paper to reduce water
conservation steam consumption, and improve machine speed.
4、 and short fiber filler effectively increase
the use of less-filler at the base may join the original cardboard,
thereby enhancing the opaque coating products without expensive and
reduce permeability of the good absorption of raw materials and
plasma surface coatings.
5、 whitewater reduce the concentration of
effective containment and control flow system bacterial growth and
reproduction rates. Black rot Pulp Pulp reduction in risk, stable
production and ensure product quality, and reduce the cost of
sewage treatment.
6、 the entire machine in the process of the
most critical parts-delivery system in a scientific, rationalizing,
economy, business is bound for the paper production, operation,
management, and marketing to after sales service to create a good
internal and external environment.
Retention and bentonite particulate filter system
and dosage
| CPAM(Kg / T paper to dry slurry of） | BT(Kg / T paper to dry slurry of） |
| 0.2-0.4 | 1.5-4 |
Research testing and production of practice
confirmed: I expected the bentonite-Dual Retention System can
reduce the promoter of the assembly, at the same time greatly
optimize treatment, Retention and absorption of the relationships
among thereby significantly improve product quality and increase
production stability. And a unit and the general dual polymer
additives at the same time it is impossible to optimize and balance
the three, in recent years bentonite particles dual Retention
System's extensive promotion and application.
Cationic polymers in the prior-pump (or
pressure ethmoidal) by adding, exports of bentonite in sieve
pressure to join with the polymer particles with a dual Retention
System. CPAM and BT dilute solutions were used measurement add
metering pump, a system of control or stop by the OCS control
switch for automatic chain.
