Abstract
The present invention relates to a kind of assay method of paper manufacturing systems ion accumulation index.It is a kind of to evaluate the method for paper manufacturing systems ion accumulation degree by determining paper manufacturing systems machine water electrical conductivity C and machine water colloidal electric charge P.And it is IA to define paper manufacturing systems ion accumulation index：IA=K0×(Cn×Pn‑C0×P0) × 100%/(C0×P0) when IA >=90%, show that the ion accumulation degree of the paper manufacturing systems is higher, the paper manufacturing systems need to arrange to clean in the recent period, as IA ＜ 90%, then show that the paper manufacturing systems arrange to clean again after can continuing to run with a period of time.Determine the ion accumulation index of paper manufacturing systems in time using the assay method, foundation will be provided in a planned way to arrange the stop cleaning of paper production system in time and reducing production loss.
Description
Technical field
The present invention relates to a kind of assay method of paper manufacturing systems ion accumulation degree in paper making process, is made by measure
The ion accumulation index of paper system, the operation conditions of paper manufacturing systems can be monitored in time, with steady production, reduce and lose.
Background technology
Rinse dosage is reduced with improving the important channel that mthod of white water from paper making circulating and recovering ratio is clean paper making, however,
After mthod of white water from paper making closing, as the fresh water amount and the wastewater flow rate of discharge that enter system greatly reduce, the interference of system is accumulated in
Material rolls up, and substantial amounts of fiber fines, filler, dissolved organic matter and inorganic salts constantly accumulate in paper manufacturing systems,
Seriously affect the steady production of paper machine, the luxus consumption of chemicals and product quality.
In actual production, due to the ion accumulation of various interference, particularly paper manufacturing systems that white water system is brought,
Often severe jamming paper production system, the Chemistry Process and product quality of paper machine are influenceed, is in particular in：(1)
Influence the normal operation of paper machine, (2) influence the performance of paper making additive effect, especially sizing agent, reinforcing agent (dry strong or wet strong),
Retention/filter aid etc., the evenness, physical strength and optical property (opacity, brightness and whiteness etc.) of (3) paper.Therefore, supervise
The ion accumulation degree of paper manufacturing systems is surveyed, is easy to arrange stop cleaning in time, ensures that paper manufacturing systems are in clean conditions operation, from
And the production obstacle brought by rotten slurry, broken end and economic loss are reduced, it is significant to paper production.
The content of the invention
It is an object of the invention to provide a kind of assay method of paper manufacturing systems ion accumulation degree, for monitoring papermaking life
The clean condition of production system, to realize that the paper production of cleaning provides guidance.
Usually, as the increase of paper manufacturing systems ion accumulation, the electrical conductivity of papermaking machine water raise, meanwhile, also lead
Cause System Charges uneven, the colloidal electric charge of plain boiled water can also increase.Therefore, the ion accumulation degree of paper manufacturing systems with it is off the net
The electrical conductivity of plain boiled water, the colloidal electric charge of machine water are proportional.
According to above-mentioned design, the present invention adopts the following technical scheme that：
It is assumed that after a certain paper manufacturing systems stop cleaning (plain boiled water in system of draining), then operation of starting shooting samples for 4 hours, measures
The electrical conductivity of machine water is C0, and the colloidal electric charge for measuring machine water is P0；Then, sample and survey after waiting the system operation a couple of days
The electrical conductivity for obtaining machine water is Cn, and the colloidal electric charge for measuring machine water is Pn, defines the ion accumulation index of paper manufacturing systems
For IA,
IA=K0 × (Cn × Pn-C0 × P0) × 100%/(C0 × P0)
In formula：K0 is experimental constant (being determined according to different types of paper manufacturing systems)
Under normal circumstances, K0=1.0
In general, if IA >=90%, show that the ion accumulation degree of the paper manufacturing systems is higher, the paper manufacturing systems need
Stop cleaning is arranged in the recent period；If IA ＜ 90%, show that the paper manufacturing systems arrange to shut down clearly again after can continuing to run with a period of time
Wash.Therefore, can be that paper production system in a planned way arranges to shut down clearly in time by the monitoring to ion accumulation index IA
Elution supplies technical basis.
The inventive method has the advantages of following apparent：
1st, this method is simple to operate, using conveniently, is advantageous to promoting the use of for enterprise.
2nd, this method evaluates the operation conditions of paper manufacturing systems with ion accumulation index, so as to be advantageous to implement cleaning life
Production, its measurement result are not disturbed by other correlative factors, and authenticity and reliability are higher, have actual application value.
