Screen printing meshs are very common in glass manufacturing applications. It is developing in all aspects of modern times. Bringing new technological power to the technical glass industry. At the same time, the performance of the glass has been greatly improved. The following is a brief introduction to the application of screen printing glass.
The glass screen printing web process is based on the principle of screen printing to print ink onto the surface of the glass. Then use the curing measures of the ink. The printed group is also relatively strong and durable. The steps of the process: stretching net → sizing → drying → printing → development → drying ↓ flat glass → cutting → edging → cleaning and drying → printing ↓ sintering.
1. Selection of screen The screen printing plate for glass printing is the same as the general screen printing plate. The glass screen printing plate is made of synthetic fiber mesh, stainless steel wire mesh and natural fiber mesh. When printing general color materials, the above-mentioned screens can be used, generally using inexpensive synthetic fiber mesh; when used as gold and silver decoration, stainless steel wire mesh cannot be selected. The specifications of the wire mesh are generally 270 to 300 mesh.
2. Suitable for printing glass According to the user's requirements, the glass can be
cut into regular shape or irregular shape, then be edged and ground, then cleaned and dried for use. Special care should be taken here that there should be no water marks on the glass surface.
3. The selection of the frame is currently more regular, the deformation of the frame is aluminum alloy frame, its size should be larger than the pattern, the specific size should be the outer edge of the pattern should be between 70 ~ 100mm. In addition to selecting the frame, its strength is very important, the key is that the rigidity in the horizontal direction is sufficient.
4. Combine the screen and the frame together and make a stretch. There are many ways to stretch the net. It can be manually, maneuvered or pneumatic. At present, the more advanced, high-quality screen version is a pneumatic stretcher. The requirement of the stretch net is that the tension is uniform, the web warp and weft are kept vertical, and the adhesive mesh is firm and cannot be slack.
The above is the application of screen printing glass.
