Description
Technical field
The present invention relates to a kind of cleaning agent and cleaning method thereof that is used for milipore filter, cleaning agent formula that particularly a kind of ceramic super-filtering film that applies to gravure note printing waste water cleans and its production and application.
Background technology
The gravure note printing technical process is the time-honored classical anti-counterfeiting printing technology that whole world seal paper money industry is generally used.Under a large amount of gravure inks is cleaned by gravure wiping liquid in intaglio process, form the gravure wiping waste liquid, this is the organic wastewater of the high chroma of a kind of COD (COD) value 2-3 ten thousand mg/l, high basicity, high concentration.The amount of the gravure wiping waste liquid that domestic seal paper money factory produces every day is about 200 tons.Its main component is materials such as NaOH, turkey red oil (sulforicinoleic acid sodium), gravure ink, and all the other are soft water.
The sodium hydrate content of wiping in the version waste liquid is 1.1%, turkey red oil content is 60%, and economic worth is about 70-80 unit/ton, and useless wiping version liquid per ton must could discharge after environmental protection treatment is up to standard, its processing cost is about 70-80 unit/ton, and the totle drilling cost of version liquid of wiping therefore per ton is between 140-160 unit.
Can reclaim NaOH, turkey red oil and soft water effectively with milipore filter, the clear liquid result of use that obtains with newly join wipe the version liquid phase with, can be directly as wiping the reuse of version liquid, this is for economizing on resources, cutting down the consumption of energy, and reduce to wipe the preparation of version liquid and the labour intensity handled significant, therefore the domestic seal paper money factory of China substantially all adopts hyperfiltration technique to give up to wipe version liquid and recycles over past ten years.
The principle that NaOH and turkey red oil are reclaimed in ultrafiltration is that milipore filter is retained down macromolecular ink particle, makes micromolecular NaOH, turkey red oil and water see through rete, obtains the reuse clear liquid.
The cleaning method of existing milipore filter has two kinds of physics method and chemical methods, and in the day-to-day operation, every day is when knocking off, and only needs to clean with the physics that the physics method was carried out several minutes to get final product.Contain various materials such as pigment, resin, Dormant oils, calcium carbonate, titanium dioxide in the gravure ink, they all can produce in various degree pollution to milipore filter, after the consequence that causes was operation a period of time, membrane flux can progressively be decayed, until the needs of can not effective supply producing.At this moment, be necessary milipore filter is carried out Chemical cleaning, its membrane flux is restored.
Great majority seal paper money factory all uses the milipore filter of organic material at present, carries out the useless recovery of wiping version liquid of gravure.
The common chemical cleaning agent has following several in seal paper money industry:
1) the following acid solution of moderate strength: phosphoric acid, citric acid, lactic acid etc.;
2) alkali lye: NaOH, sodium carbonate etc.;
3) surfactant: ionic or nonionic;
4) compounding ingredient: EDTA, polyacrylate, calgon.
These cleaning agents both can use separately, also can combining form use.Acid solution makes a part of insoluble substance in the pollutant become solable matter; Alkali lye and surfactant are used to remove grease and small organic molecule matter, and complex can become the big material of solubility with the inorganic ions complexing in the pollutant, reduce the long-pending salt of film surface area and inner hole deposition and the inorganic pollution of absorption.
In seal paper money industry, traditional film cleaning method is that soda acid alternately cleans.Because the characteristics that organic film itself is easily aging, cause strong acid not use, the concentration of highly basic can not be joined very highly, so that milipore filter can not thoroughly be cleaned, general organic hollow cellulosic ultrafiltration film used about half a year, just can not recover by Chemical cleaning because of flux falls to the greatest extent, perhaps rete is damaged and scrap.
Summary of the invention
What the present invention will solve is exactly the defective that above-mentioned prior art exists, and one of purpose of the present invention is to provide a kind of inorganic ceramic milipore filter cleaning agent;
Two of purpose of the present invention is to provide the preparation method of this cleaning agent;
Three of purpose of the present invention is to provide the application of this cleaning agent.
Goal of the invention of the present invention is achieved by the following technical solution:
A kind of new ceramics milipore filter cleaning agent is made up of A component and B component, wherein:
The A component is dissolved by weight percentage by following component and forms:
Weight percentages of components
NaOH 5-20%
Sodium alkyl benzene sulfonate 5-10%
Sodium carbonate 5-10%
All the other are water;
The B component is dissolved by weight percentage by following component and forms:
Weight percentages of components
Nitric acid 1-5%
Hydrogen peroxidase 10 .5-3%
Clorox 0.5-2.5%
All the other are water.
Above-mentioned new ceramics milipore filter comprises the steps: with the preparation method of cleaning agent
A, in the stainless steel purge tank of the anti-nitric acid that a band stirs, add running water, NaOH, sodium alkyl benzene sulfonate, sodium carbonate successively by proportioning, at room temperature stirred 10-30 minute, promptly get the A component of liquid cleaner of the present invention;
B, in the stainless steel purge tank of the anti-nitric acid that a band stirs, add running water, nitric acid, hydrogen peroxide, clorox successively, at room temperature stirred 10-30 minute, promptly get the B component of liquid cleaner of the present invention.
Above-mentioned new ceramics milipore filter is used to reclaim the cleaning that gravure note printing is wiped the ceramic super-filtering film of version waste liquid with cleaning agent, and cleaning step is:
The first step: cleaning agent A component is heated to 40-70 ℃, opens clear liquid side valve door wash cycles, close clear liquid side valve door wash cycles after waiting to produce flux, the cumulative time stops to clean emptying A component after reaching 2-4 hour;
Second step: cleaning agent B component is heated to 40-70 ℃, open clear liquid side valve door wash cycles, the cumulative time stops to clean after reaching 2-4 hour, valve-off is stayed cleaning agent B component ceramic membrane is immersed in wherein, soaks last emptying cleaning fluid of a week;
The 3rd step: after the repeated washing first step, whole cleaning process finishes.
Cleaning agent of the present invention makes the oxidized small-molecule substance that is decomposed into of macromolecular resin class material by the introducing to the strong acid strong oxidizer; One to two day the immersion at weekend makes more thorough, the reinforcement of this oxidizing process; The NaOH of high concentration makes the organic substance and the Dormant oils that are decomposed be dissolved band up hill and dale from the film surface.These factors all make cleaning process more powerful.
Cleaning agent of the present invention has following advantage than the conventional clean agent:
1. lower the concentration polarization on film surface greatly, reduced the cleaning frequency of film.
2. recover the filtration flux of ceramic membrane effectively, completely, make system obtain regeneration.
3. the longer service life of milipore filter.
