Glass technology | printing glass is what?
Screen printing glass is an application of glass screen printing process, decorative printing on the surface of glass, and then fired at high temperature and become a decorative glass.
Glass screen printing is the use of screen printing plate, the use of glass glaze, on the glass products for decorative printing.
Glass glaze, also known as glass ink, glass printing material, it is a paste printing material mixed by coloring material and binder.
Coloring material by inorganic pigment, low melting point flux (lead glass powder) composition;
Links in the glass screen printing industry commonly known as suet.
The printed glass products should be put in the furnace and fired at a temperature of 520~600℃. The glaze printed on the surface of the glass can be consolidated on the glass to form a colorful decorative pattern.
If the screen printing and other processing methods used together, it will get more ideal results.
For example, using polishing, engraving, etching and other methods to process the glass surface before or after printing can double improve the printing effect.
Glass City Glass Trading Platform takes you to see several types of silk screen cabinet glass:
That exactly is the silk screen glass how to produce?
Specific process flow of screen printing glass:
Stretch net → sizing → drying → plate printing → developing → drying ↓ flat glass → cutting → edging → cleaning and drying → printing ↓ sintering.
Although it is quite simple to look at the process, there are many places to pay attention to in the specific operation:
1, suitable for printing glass according to user requirements to cut glass, can be regular shape, can also be irregular shape, and then chamfer grinding, cleaning, drying for use.
Special care should be taken here that there should be no water stains on the glass surface.
2, the choice of screen glass printing screen printing plate and general screen printing plate, glass printing plate selection of synthetic fiber screen, stainless steel screen, natural fiber screen.
When printing general colors, the screen can be, generally choose cheap synthetic fiber screen;
As gold and silver decoration, can not choose stainless steel screen.
Screen specifications generally 270 ~ 300 mesh.
3, the selection of the mesh frame is currently more regular, small deformation of the mesh frame is aluminum alloy mesh frame, the size should be larger than the pattern, the specific size should be the pattern of the outer edge of the mesh frame should be between 70 ~ 100mm.
In addition, the choice of mesh frame, its strength is very important, the key is enough horizontal rigidity.
4, the tension network chose the screen and the screen frame, the combination of the two, this is the tension network.
There are many ways to stretch the network. Manual, motor and pneumatic methods can be used. At present, the more advanced one that can stretch the high quality screen version is the pneumatic stretch network machine.
The tension of the network is uniform, the latitude and longitude of the network are vertical, and the mesh glue should be firm and can not be relaxed.
