Description
Technical field
The invention belongs to paper industry retention aid and filtering aid technical field, be specifically related to a kind of method of adding double base retention and drainage aid agent in production process of corrugated paper.
Background technology
Flourish along with paper-making industry, paper industry also exposes more problem in producing, and mainly contains raw material, energy scarcity and problem of environmental pollution.In paper industry production process, along with the raising of paper machine speed, Secondary Fiber Recycling amount also increases thereupon, plain boiled water cycling rate is also higher, but this makes wet end of machine system decline to tiny component and the retention of other auxiliary agent and the water filtering performance of slurry thereupon, and it is serious to cause paper pulp fiber to run off with plain boiled water, heavy system plain boiled water pollutional load, reduces system cleanliness factor.All these put forward new requirement to becoming the retention and water filtering performance that improve wet end in paper process and reducing plain boiled water pollutional load.
In paper-making process, tiny component, filler and additive add the consumption that can reduce slurry and auxiliary material.This not only can reduce the consumption of slurry auxiliary material, but also can reduce concentration and the COD content thereof of plain boiled water, reduces production cost to a certain extent.So the tiny component should kept here in paper industry forming process in slurry and filler as far as possible, and strengthen the dehydration of wet end of machine, the effective way of less expensive uses efficient retention and drainage aid agent now as far as possible.
Paper retention and filter aid is of a great variety, and often kind of retention and drainage aid agent characteristic, effect, the scope of application are not quite similar.All adopt single retention and drainage aid agent in current traditional production process of corrugated paper, treatment effect or be that retention is low, or be exactly water filtering performance difference, cause the retention of the tiny component of slurry and filler low, machine water COD content is high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of adding double base retention and drainage aid agent in production process of corrugated paper, to improve the retention of the tiny component of slurry and filler and to reduce the COD content of machine water.
The present invention solves the problems of the technologies described above with following technical scheme:
Add the method for double base retention and drainage aid agent in a kind of production process of corrugated paper of the present invention, comprise the following steps:
(1) the modified alta-mud aqueous solution of compound concentration to be the cationic polyacrylamide aqueous solution of 1g/L and concentration be 100g/L;
(2) by mass concentration be 0.8% pulp be placed in dynamic drainage instrument, at ambient temperature, stir under the rotating speed of 700 ~ 800r/min, then 12 ~ 14ml cationic polyacrylamide aqueous solution is added by 1L pulp, after stirring 15s, 4 ~ 8ml modified alta-mud aqueous solution is added again, after stirring 15s by 1L pulp.
The compound method of the described cationic polyacrylamide aqueous solution is: 0.1g cationic polyacrylamide is put into 100ml deionized water, stirs.
The compound method of the described modified alta-mud aqueous solution is: added in 200ml deionized water by 20g modified alta-mud, stir.
The molecular weight of described cationic polyacrylamide is greater than 500,000.
The inventive method adopts double base retention aid and filtering aid system, both the retention of tiny component and filler can have been improved, also can improve the water filtering performance of slurry, and reduce the COD content of machine water significantly, for realizing paper industry white water system and zero-emission plays a significant role.
The inventive method can effectively make the tiny component of slurry and the retention of filler improve 2.3 ~ 5.8% and 9.6 ~ 13.1% respectively, and significantly can reduce the COD content of filtrate, reaches 5.1 ~ 23.4%.On the one hand, the raising of the tiny component of slurry and filler retention, saves fibrous raw material, improves water filtering performance, improves paper machine operation speed, is conducive to reducing paper industry production cost; On the other hand, the COD of filtrate (i.e. plain boiled water) reduces, and makes wet end more clean, has promoted further developing of paper industry white water system and zero-emission.
