Description
Technical field
The present invention relates to a kind of metal surface treating method, especially a kind of promotions by ph balancing process
The method of metal surface rustless property.
Background technology
Currently, in product on the market, especially metal product influences product itself use because of burn into problem of rustiness,
The problem of even resulting in product rejection is countless, caused by loss be also inestimable, the main original of product corrosion
Because be hardware after cutting or processing and forming element exposure in air inevitably by oxygen, aqueous vapor or
Chemistry or electrochemical action occur for the erosion of all kinds of corrosive substances, to cause the corrosion to hardware.This phenomenon goes out
It is typically now caused by metal is influenced by media such as atmosphere moisture, oxygen or other corrosive gas.Therefore, to product
The work of the antirust of antirust, especially metal product is extremely urgent.Current metal rust preventing primarily directed to Treatment of Metal Surface,
Main processing mode can be divided into following several types；1- surface mechanical enhancements, the surfaces 2- conversion film, 3- surface sprayings,
In industrial more commonly used predominantly first two, surface mechanical enhancement and surface convert film, and wherein surface mechanical enhancement is main
Including；Shot-peening/sand processing, rolling and processing, inner hole extruding, wire drawing, polishing and polishing etc., surface conversion film include mainly；Oxidation
Processing, phosphorating treatment, plating, chemical plating, electroforming (a kind of special applications of plating), electrophoresis and electropolishing etc., but it is above-mentioned several
Kind processing method is but haveed the shortcomings that many.The shortcomings that surface mechanical enhancement：
1, product surface compacted zone and its limited, easily wears, scratches；
2, certain equipment and auxiliary clamp class are needed, is handled, investment is larger, and processing time is also longer；
3, the processing means such as sandblasting, polishing have personnel certain harm, easily form occupational disease.
Convert the shortcomings that film in surface：
1, product surface is susceptible to the defects of spot, striped, uneven, heterochromatic processing；
2, conversion film in surface is mainly to be handled in chemical or electrochemistry mode, and Long Term Contact chemical classes medicament is to people
Body is harmful.
3, it is had a certain impact to environment using the sewage generated after chemistry or electrochemical means processing, needs ability after processing
It can discharge；
In addition, film is converted on surface, it includes mainly；Oil spout (solvent based coating), dust (powdery paints), but oil spout pair
It is more demanding to facility environment for appearance member product, it is necessary to reach dustfree environment requirement, equipment investment is larger, to personnel
Technology requires also higher；And the environment that dusts must be noted that " dust " endangers, there are some potential safety problemss.
