Description
Technical field
The present invention relates to part treatment process, especially suitable for requiring coating layer thickness in the aluminum piston stone of 0.015-0.03mm
A kind of technique of raising aluminum piston graphite silk-screen printing coating layer thickness of black silk-screen printing.
Background technique
The coating thickness requirement of aluminum piston graphite silk-screen printing is generally 0.01mm-0.02mm in industry.Aluminum piston graphite
The prior art of silk-screen printing are as follows: cleaning, drying-graphite printing-levelling solidification, detailed process and operation are as follows:
The effect of equadag coating is early stage adjustment lubrication, needs certain thickness and adhesive force, at present more and more visitors
Family requires graphite silk-screen printing coating layer thickness to reach 0.015mm-0.03mm.
Have in the major way that prior art increases graphite silk-screen printing coating layer thickness:
1, printing pressure is reduced；
2, increase silk screen at a distance from Workpiece printing；
3, increase the angle of scraper plate and silk screen；
4, increase silk screen line footpath and photosensitive layer thickness；
5, reduce meshcount.
But it has the disadvantage in that through the above way
1, increase silk screen at a distance from Workpiece printing, to increase the angle of scraper plate and silk screen be also a kind of reduction printing pressure
Mode.It is appropriate to reduce pressure, enough spaces are reserved, can increase the thickness of equadag coating, but incrementss very little, generally not
More than 0.005mm, while the operation adjusts difficulty and very risky, and hypotony, which will cause, does not print, and reduces graphite instead
Coating layer thickness.
2, increase silk screen line footpath and photosensitive layer thickness is the length for increasing the storage of silk screen hole and staying graphite, reduce meshcount
When increase the diameter in silk screen hole, be all the amount that graphite is stayed by increasing storage, graphite is coated to work through silk screen when ensureing printing
Amount beyond the Great Wall, to increase coating layer thickness, this increased thickness of mode is usually no more than 0.007mm, and silk screen line footpath increases
Big and mesh number reduces, and will lead to equadag coating becomes coarse, influences appearance, or even influence graphite adhesive force.
