Abstract
The invention provides a ternary retention and drainage method for offset paper. The method comprises the following steps of: (1) adding a charge neutralizer into a white water tank, (2) adding CPAM (cationic polyacrylamide) reagent after completing the sand removal procedure and before entering a deaerator, and (3) adding APAM (anionic polyacrylamide) reagent after completing the pressure screening procedure and before entering a head box. The invention has the advantages that: the application of a ternary retention and drainage system in the offset paper-making process increases the wet-end retention rate, reduces machine water and greatly improves paper evenness. Besides, since the retention rate is increased, the shutdown cleaning frequency is reduced and the load of sewage treatment is reduced, resulting in significant economic benefits.
Description
Affiliated technical field
The invention belongs to paper-making technology, especially a kind of method of offset paper ternary retention aid and filtering aid.
Background technology
The retention aid and filtering aid system of culture paper generally adopts cellular system; Promptly use a kind of cationic auxiliary to be added on the retention that improves paper fibre, filler etc. before or after the pressurized screen; This system cost is the most cheap, but paper exists the two sides poor, and fiber, filler etc. are a large amount of simultaneously runs off; Double base retention aid and filtering aid system appears in recent years; Mainly be in slurry, to add in a kind of positive polymer and electric charge; The polymer or the particulate that add a kind of feminine gender in pressurized screen outlet are wadded a quilt with cotton the fiber of breaing up again and are gathered; The drawback that this kind technology exists is the auxiliary agent interpolation little auxiliary DeGrain in the pressurized screen outlet, and the formation of sheet extreme difference floc sedimentation appears, in addition big auxiliary agent paper easily.
Summary of the invention
The method that the objective of the invention is to avoid the deficiency of prior art and a kind of offset paper ternary retention aid and filtering aid is provided.
Technical scheme of the present invention is: a kind of method of offset paper ternary retention aid and filtering aid, press the paper technology step: 1) in the plain boiled water bucket, add the electric weight neutralizer; 2) after the desanding operation is accomplished, get into deaerator and add CPAM reagent before; 3) accomplish in the pressurized screen operation and laggardly add APAM reagent before going into head box.
The electric weight neutralizer that is added is 0.3-0.6 kilogram/ton paper, and CPAM reagent is 0.5 kilogram of/ton paper; APAM reagent is 0.3-0.5 kilogram/ton paper.
Added electric weight neutralizer concentration is 10%, drops to the paper machine white water bucket under the normal temperature and pressure.
Added CPAM concentration is 0.1-0.05%, under the pressure of 0.25-0.5MP, is added to the desanding jar.
Added APAM concentration is 0.1-0.08%, is added to pressurized screen under the pressure with 0.25-0.5MP.
Advantage of the present invention is: adopt ternary retention aid and filtering aid system to copy the paper offset paper and copy paper wet end retention and improved, machine water descends, and formation of sheet is greatly improved; Improve because of retention simultaneously; Prolonged and shut down the cycle of cleaning, alleviated the sewage disposal load, economic benefit is obvious.
The specific embodiment
Embodiment 1:
A kind of method of offset paper ternary retention aid and filtering aid is pressed the paper technology step and is produced, and in the plain boiled water bucket, adds the electric weight neutralizer of 0.3 kilogram of/ton paper; , the desanding operation gets into the CPAM reagent that deaerator adds 0.5 kilogram of/ton paper before after accomplishing; 3) accomplish the laggard APAM reagent that adds 0.3 kilogram of/ton paper before going into head box in the pressurized screen operation.
Electric weight neutralizer concentration is 10%, drops to the paper machine white water bucket under the normal temperature and pressure; CPAM concentration is 0.1%, under the pressure of 0.5MP, is added to the desanding jar; APAM concentration is 0.1%, is added to pressurized screen under the pressure with 0.5MP.
The electric weight neutralizer uses in the high charge density cationic material and the anionic impurity in the plain boiled water; Especially offset paper is done raw material with a large amount of non-wood pulp material (like Straw Pulp, rice straw pulp, mechanical poplar slurry etc.); There are a large amount of anionic impurities in the system, need the power consumption neutralizer to neutralize these goods and materials.Become big floccule through the pulp-water, filler of neutralization with the CPAM combinate form of wadding a quilt with cotton; Break up through pressurized screen and form small floccule, use APAM wads a quilt with cotton again to gather to reach to help and stays the hybrid system effective, that evenness is good to get into the head box Top wire former before approach flow.
With 2640 paper machines is example: machine water dropped to 0.15% by former 0.25-0.35 after adopting ternary retention aid and filtering aid system; Retention has improved 10%;, formation of sheet is greatly improved, and improves because of retention simultaneously; Prolonged and shut down the cycle of cleaning, extended to 10 day by former 7 days downtime; Because system has cleaned, and the centering water treatment is loaded also to have necessarily and alleviated, increased economy and imitate about 150,000 yuan in every month simultaneously.
Embodiment 2:
A kind of method of offset paper ternary retention aid and filtering aid is pressed the paper technology step and is produced, and in the plain boiled water bucket, adds the electric weight neutralizer of 0.6 kilogram of/ton paper; , the desanding operation gets into the CPAM reagent that deaerator adds 0.5 kilogram of/ton paper before after accomplishing; 3) accomplish the laggard APAM reagent that adds 0.5 kilogram of/ton paper before going into head box in the pressurized screen operation.
Added electric weight neutralizer concentration is 10%, drops to the paper machine white water bucket under the normal temperature and pressure; Added CPAM concentration is 0.05%, under the pressure of 0.25MP, is added to the desanding jar; Added APAM concentration is 0.08%, is added to pressurized screen under the pressure with 0.25MP.
With 2640 paper machines is example: machine water dropped to 0.1% by former 0.25-0.35 after adopting ternary retention aid and filtering aid system, and retention has improved 14%; Formation of sheet is greatly improved; Because of retention improves, prolonged and shut down the cycle of cleaning simultaneously, extended to 15 days downtime; Because system has cleaned, and the centering water treatment is loaded also to have necessarily and alleviated, increased economy and imitate about 250,000 yuan in every month simultaneously.
