Abstract

The invention discloses a kind of pre- sealing of hole secondary oxidation techniques, wherein is as follows:(1) it treats product and carries out once oxidation;(2) after completing, following process is carried out;(3) it is cleaned;(4) primary washing;(5) acid-base neutralization is carried out to product surface;(6) secondary washing is carried out;(7) to carrying out pre- sealing pores by the product of once oxidation, the oxidation film crackle being destroyed after once oxidation is repaired;(8) it is washed three times;(9) then, secondary oxidation is carried out.There is the present invention property patience for improving oxidation film adhesive force and product to be oxidized to test the effect improved greatly.

Description

A kind of pre- sealing of hole secondary oxidation technique
Technical field
The present invention relates to a kind of pre- sealing of hole secondary oxidation works that the product to aerobicization such as TV machine frame, mobile phone shells carries out Skill.
Background technology
Currently, market product to be oxidized is after once oxidation, so that it may to carry out subsequent technique processing.Due to passing through The product of once oxidation, oxidation film are more easily damaged, and cause the oxidation film of product surface easy to fall off, and the qualities such as adhesive force deficiency are asked Topic.
Invention content
In view of the above problems, the purpose of the present invention is to provide a kind of raising oxidation film adhesive force and products to be oxidized Property patience test the pre- sealing of hole secondary oxidation technique that improves greatly.
To achieve the above object, a kind of pre- sealing of hole secondary oxidation technique provided by the invention, wherein be as follows: (1) it treats product and carries out once oxidation;(2) after completing, following process is carried out;(3) it is cleaned;(4) primary washing;(5) Acid-base neutralization is carried out to product surface;(6) secondary washing is carried out;(7) to carrying out pre- sealing pores by the product of once oxidation, The oxidation film crackle being destroyed after once oxidation is repaired;(8) it is washed three times;(9) then, secondary oxidation is carried out.
The beneficial effects of the invention are as follows with the big raising of property patience test for improving oxidation film adhesive force and product to be oxidized 's.Due to comparing with existing secondary oxidation technique, increase after increasing pre- hole-sealing technology and third time washing, so It has repaired the oxidation film being destroyed after once oxidation, yields and the property patience of product is made to test big improve.
Specific implementation mode
Invention is described in further detail below.
A kind of pre- sealing of hole secondary oxidation technique, is as follows:(1) it treats product and carries out once oxidation;(2) it is completed Afterwards, following process is carried out;(3) it is cleaned;(4) primary washing;(5) acid-base neutralization is carried out to product surface;(6) it carries out secondary Washing;(7) to carrying out pre- sealing pores by the product of once oxidation, the oxidation film crackle being destroyed after once oxidation is carried out It repairs;(8) it is washed three times;(9) then, secondary oxidation is carried out.It compares, increases with existing secondary oxidation technique After the pre- hole-sealing technology of increase and third time are washed, so repaired the oxidation film being destroyed after once oxidation, make yields and The property patience test of product is big to improve.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to the protection domain of invention.
