Abstract
The treating process of eliminating vacuum coating includes the following steps: 1. soaking the product with coating to be eliminated in solution of acid and hydrogen peroxide; and 2. soaking the product in clear water to eliminate the residual coating and solution. The said process can eliminate the coating fast from the product for re-processing, and has low material cost and simple environmentfriendly waste liquid treatment.
Description
Technical field
The present invention relates to a kind of chemical removal method, particularly relate to a kind of treatment process of removing vacuum plating.
Background technology
Vacuum coating can be imitated complete bright decorative coatings such as gold, imitative silver and imitative other metals.It adopts the vacuum plating unit film forming, at the coating method of the closed circuit drying tunnel of the whole series, has stopped depleted high density chromic acid and vitriolic alligatoring waste liquid and chemical nickel plating waste solution in the plating production process.Stopped the discharging and the pollution of heavy metal wastewater therebies such as acid, alkali, chromium, nickel, copper in the plating production process.Obtained using widely in modern society.But in long-term practicality, it is unusual that various flaws can appear in the vacuum metallization film surface, such as jaundice, oxidation spots occurs.General method is to plate one deck stainless steel rete again at original plated film it is covered, and so repeatedly heavily plating causes attached outstanding power in poor shape, and easily easy deformation produces trouble and inconvenience so in use, remains in fact to be improved.
Summary of the invention
The invention provides a kind of treatment soln method of removing vacuum coating.By in suitable chemical medicine configuration solution, soaking,, product recovery material situation is processed again with the quick flush away of the metallic diaphragm of product surface.Raw materials used cost is low, easily obtains, and the simple environmental protection of liquid waste disposal.
For reaching above-mentioned effect, the present invention adopts in the following method:
A kind of treatment process of removing vacuum coating, wherein, described treatment process comprises the steps: at least
Step 1: required removal plated film product is soaked in the solution of sulfuric acid and hydrogen peroxide;
Step 2: product is placed in the clear water soaks, remain in plated film and solution on the product with removal.
Described a kind of treatment process of removing vacuum coating, wherein, described solution ratio ratio is: pure water 70%-75%, sulfuric acid 15%-20% and hydrogen peroxide 10%.
Described a kind of treatment process of removing vacuum coating is characterized in that, in the described step 1, the time of described immersion is 10～20 seconds.
Embodiment
Below the present invention is further detailed explanation: for reaching above-mentioned effect, the present invention adopts in the following method:
A kind of treatment process of removing vacuum coating, wherein, described treatment process comprises the steps: step 1 at least: required removal plated film product was soaked in the solution of sulfuric acid and hydrogen peroxide 10～20 seconds; Step 2: product is placed in the clear water soaks, remain in plated film and solution on the product with removal.After clear water cleaned, the product that has been returned to can be handled again like this.
Wherein the solution ratio ratio is: pure water 70%-75%, sulfuric acid 15%-20% and hydrogen peroxide 10%.
As from the foregoing, the chemical solvents of the present invention's employing is sulfuric acid and two kinds of materials of hydrogen peroxide.By suitable proportioning configuration solution, the workpiece that needs are removed rete is placed directly in the solution and soaks for some time, and under the oxygenizement of sulfuric acid and hydrogen peroxide, metallic diaphragm can dissolve, and reaches the purpose of removal, so again coating film treatment.And the waste liquid after using can add appropriate bases therein and neutralizes remaining sour aftertreatment fully, can not exert an influence to environment.
The above; only be the preferable feasible embodiment of the present invention; can not therefore promptly limit to interest field of the present invention; concerning being familiar with those of ordinary skill in the art; such as use technical scheme of the present invention and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong within the protection domain of claim of the present invention.
Claims (2)
1. a treatment process of removing vacuum coating is characterized in that treatment process comprises the steps: at least
Step 1: required removal plated film product is soaked in the solution of strong acid and hydrogen peroxide;
Step 2: product is placed in the clear water soaks, remain in plated film and solution on the product with removal;
Wherein, described solution ratio ratio is: pure water 70%-75%, sulfuric acid 15%-20% and hydrogen peroxide 10%.
2. a kind of treatment process of removing vacuum coating according to claim 1 is characterized in that, in the described step 1, the time of described immersion is 10～20 seconds.
