Description
Technical field
The invention belongs to the field of test technology, are related to a kind of sicker removal effect of cleaning additive in paper industry
Evaluation method is the experimental method for selecting sicker removal auxiliary agent.
Background technique
Sicker in paper pulp is typically derived from the impurity such as ink, adhesive in secondary stock.During waste paper pulp-making,
The property of sicker in waste paper can also change, and into after paper manufacturing systems, these sickers tend to be deposited on paper machine
The positions such as forming net, woollen blanket, pressure roller or drying cylinder, cause mesh to block, paper made to generate diaphanous spot, or even cause paper machine disconnected
Paper influences normally production and product quality.Such case is more prominent in the factory of production newsprint.
There are much reports about sicker remover at present, but few about sicker removal effect evaluation method
Report.Chinese patent CN 101498640A discloses a kind of evaluation method, is to stay in filtering after penetrating filter membrane by measurement filtrate
The turbidity of the number of inventory on film and filtrate, cationic demand characterize sicker removal effect.The patent mentions
Method out has the following disadvantages that (1) often has large error using the method for measuring trapped substance weight after filtering, because of glue
Viscous object itself is relatively light, and the content of sicker is relatively low in paper pulp in actual production, in pattern sicker number it is general
It will not cause the significant change of trapped substance weight on filter membrane.(2) indexs such as the turbidity of filtrate and cationic demand often by
To the influence of added sicker removal auxiliary agent, interference is brought to actual determination data.(3) the experiment side that the patent discloses
Method is simply to be filtered slurry, and this drainage process is a kind of simple static drainage mode, in papermaking actual production
Dynamic drainage mode gap it is bigger.Therefore, which is often difficult to simulate actual production situation in practical applications,
Measurement result can also lack practical application value.
The object of the present invention is to provide a kind of sickers of cleaning additive in evaluation paper industry that can overcome drawbacks described above
The method of removal effect.
Summary of the invention
It is an object of that present invention to provide a kind of methods of improved evaluation sicker remover effect in paper production.It is real
On border, the formation of sicker obstacle and paper making process are closely related, especially the addition manner and wire-cloth of cleaning additive
Upper drainage process is particularly important to the removal effect of sicker obstacle.It therefore, if can be in simulation papermaking actual production process
It is tested under conditions of dynamic drainage, and Experimental comparison is carried out using different cleaning additive addition manners, gained experiment is commented
Valence result certainly will be practical closer to production.On the other hand, it is contemplated that sicker obstacle is accumulation formation in actual production, and paper
The content of sicker is not very high in slurry, therefore when we directly take paper pulp to test, and the comparison of experimental result is often not
It is big obvious.For this purpose, we are in slurry preparation, the sicker accumulated when forming sicker obstacle in actual production is added in supplement,
The adhesive content in paper pulp is improved, to keep experimental data comparison more obvious.In addition, sicker is gone in paper-making process
Except effect is better, black splotch is also fewer on pattern, and therefore, the statistical result of stain quantity most can directly reflect on pattern
Removal effect of the sicker remover to sicker.
Based on the above design, the invention proposes following evaluation methods:
The evaluation method of a kind of cleaning additive to sicker removal effect, it is characterised in that this method uses the system of slurry
The process that standby, copy paper, squeezing, drying, pattern are analyzed carries out, the specific steps are as follows:
The preparation of slurry: it is carried out using mechanical machine,massing, and 0.5 ~ 10% sicker is added before mashing；
The addition of cleaning additive: being added cleaning additive before mashing or after mashing according to the design of experimental program, if
Cleaning additive is added after mashing, then needs to continue after cleaning additive is added to be dispersed with stirring 3 ~ 10min, mixing speed 200 ~
It is arbitrarily chosen within the scope of 500rpm；
Page is manufactured paper with pulp: being formed using blender (1), draining tank (2), strainer (3), bottle,suction (4), vacuum pump (5)
The dynamic drainage forming process of copy paper unit simulation paper machine carries out pattern and manufactures paper with pulp；
Squeezing, the drying of pattern: squeezing Shi Xianyong idler wheel carries out first pressing 5 ~ 10 times, then with hydraulic press 0.2 ~
1 ~ 10min is squeezed under 1.0MPa pressure, pattern can be obtained in drying at a temperature of 50 ~ 150 DEG C；
Pattern analysis: to the statistics of surface black spot, auxiliary agent is characterized by the removal rate of pattern surface stain
Effect, sicker removal effect exponential formula are as follows: R=K0(C0-C)/C0, in formula: R is sicker removal effect index, K0To be
System parameter, it is related with pulp varieties, generally, K0=1.0, C are pattern surface stain quantity, C0For blank sample surface stain number
Amount.
The strainer of above-mentioned copy paper device is the strainer for any mesh number selected between 50 ~ 200 mesh.
The blender of above-mentioned copy paper device is stepless speed-regulating stirrer, and speed adjustable range is 200 ~ 3000rpm.
Compared with other evaluation methods, the present invention can simulate papermaking actual production conditions, and have easy to operate, result
The advantages of reliable and stable, data are not interfered by other factors.
