The treadmill digital printing machine does not block the net, the key depends on the glue

The rheological properties of the rubber slurry of the treadmill digital printing machine are also easy to cause network jam. 2. The choice of crosslinking agent. The cross-linking agent can cross-link the linear structure of the adhesive into a network structure and form a film on the fabric. Generally, it is required that the pigment printing paste does not increase the viscosity, which is beneficial to not block the net. 3. The choice of adhesive. Binder is one of the main components of paint color paste. The fastness of the printed pattern of the treadmill digital printing machine and whether the screen is blocked depends on the quality of the adhesive. It should be selected with good thixotropy, strong adhesion, high color yield, slow film formation, and good filterability. An adhesive that is easy to operate, does not turn yellow after baking, and has a soft hand feeling. 4. Urea is a hydrophilic substance, which has hygroscopic and solubilizing effects. Adding a proper amount of urea to the printing pattern color paste of the treadmill digital printing machine can solve the skinning problem of the adhesive, improve the rheological properties of the color paste, and help the scraper to smoothly print and prevent network clogging. 5. Treadmill digital printing machine printing grey fabric requires good surface finish, and singeing is required to be level 3 or above to reduce short hair on grey fabric and prevent network jamming. 6. The squeegee has good elasticity and clean color, so that the paint color paste has a strong penetrating ability and prevents the network from clogging. Pay attention to the flatness of the blade edge and the curvature of the blade surface. If the blade edge is not flat and the blade surface is curved, the elasticity of the blade is inconsistent, which will cause the inner wall of the cylinder to be unclean and cause net jamming. 7. Paint color paste is easy to condense at high temperature. Pay attention to the temperature changes in the workshop. In high temperature seasons, you can add glycerin or urea to the color paste. The color paste should be filtered before running on the digital printing machine on the treadmill. The mesh number of the nylon mesh It should be twice as large as the mesh of the rotary screen. 8. The particle size of the paint has a great influence on the plug network, and some paints have a relatively coarse particle size and should not be used. 9. The rubber guide belt should be kept flat and clean. If there is dry slurry condensation, the surface is uneven, the elasticity is reduced, and the uneven pressure of the scraper will cause the treadmill digital printing machine to block the network. The reverse side of the guide belt and the support shaft of the guide belt should be used frequently Organic solvent cleaning. 10. After the treadmill digital printing machine shuts down, the color paste pattern should be cleaned immediately, and the areas that are not clean should be sprayed with a spray gun to prevent conjunctiva and cause network clogging.
