Steaming gauze analysis of the problem of sticky hand after printing the printing paste. 1. The problem of sticking the hand after printing the printing paste. The printing paste has a sticking phenomenon after drying, and it is more serious with the increase of temperature.
Reason: The main raw material of printing paste is acrylic resin. The characteristics of the resin are determined. The harder resin is used. The problem of sticking can be solved, but the adhesion is very serious. If the adhesion is increased, the softer resin must be selected. But the soft resin is easy to stick back.
Solution: Use the printing glue anti-adhesive agent produced by Dongguan Aoda Chemical Co., Ltd., and add it into the printing glue to mix evenly. After printing, the printing glue anti-adhesive agent can form a film on the surface, which does not affect the printing glue. The adhesion of the pulp solves the problem of sticking hands.
2. Solution to the phenomenon of plugging net in flat net fabric printing
Reason: The density of the manuscript film is not enough; the operation process of the flat plate plate making process is improper; the quality of the printing paste is problematic.
Solution:
The original film is currently produced by computer. The higher the black pattern density of the bottom sheet, the better the shading effect. If the blackness is not enough, the shading effect is worse, the ultraviolet light is easy to pass through, which will cause the net to be plugged; the fog of the bottom film is low, such as high fogging, blocking the transmission of ultraviolet light, and it is necessary to lengthen the exposure time. This is done, which is easy to cause excessive exposure time and create a net.
Improper development and curing of the flat screen plate will result in a net. When developing, it is necessary to consider that the ultraviolet light is transmitted from the printing surface of the screen to the squeegeing surface, the printing surface is fully illuminated, and can be washed with water of a relatively large pressure; and the degree of cross-linking of the squeegee surface is smaller than that of the printing surface, and the film is displayed. When tender, rinse with a non-pressure slurry of water to avoid clogging the mesh. Double exposure should be carried out before curing to make the adhesive layer fully sensitized and then apply the curing agent.
In the printing, the used slurry contains impurities or undissolved particles to block the mesh, so that the color paste cannot be scraped out from the mesh during printing, so the slurry should be filtered to remove impurities before use. When choosing a coating adhesive, choose a good quality adhesive and a compatible thickener. The film should not be too fast when scratching.
