The spot uv coating machine is an important equipment for post-printing surface finishing and production. It plays a very important role in improving the surface properties of printed products, improving the wear resistance and water resistance of printed products. For the coating machine with ordinary rubber rollers, the oil amount of the coating oil is controlled by the gap between the oil control roller and the rubber roller. The gap is adjustable. When the oil amount is large, the gap is increased, and when the oil amount is small, the gap is reduced. Because it is manually operated, it is not easy to accurately control the oil amount of the coating machine, and the adjustment is relatively cumbersome; on the other hand, the oil control roller and the rubber roller will inevitably have precision errors during manufacturing; the rubber roller has a short service life, needs to be replaced frequently, and is prone to deformation; these factors will lead to uneven oil application, affect the coating effect, and increase the cost of use.
Feihua spot uv coating machine FHSGJ-1050 uses ceramic anilox rollers, which can more accurately control the oil amount, that is, the thickness of the oil film after coating, than the coating machine with ordinary smooth oil control rollers in the past, and can effectively make up for the shortcomings of the short service life and easy deformation of the rubber roller, and ensure the uniformity of the coating oil film in all directions.
Advantages of ceramic anilox rollers:
1. Strong wear resistance: Ceramic anilox rollers have extremely high hardness and wear resistance, and can maintain good anilox quality during long-term use and extend service life.
2. Good corrosion resistance: Ceramic anilox rollers have excellent corrosion resistance and can be used in harsh environments such as acid and alkali, and are not easily corroded and damaged.
3. Good thermal conductivity: Ceramic anilox rollers have good thermal conductivity and can quickly transfer heat to the working material to improve production efficiency.
4. Smooth surface: The surface of the ceramic anilox roller has been finely processed and has a high degree of smoothness, which can reduce the friction resistance with the working material and improve work efficiency.
5. High precision: The manufacturing process of ceramic anilox rollers is fine, and high-precision anilox can be produced to ensure the quality and effect of processes such as printing, coating and calendering.
6. Good temperature stability: Ceramic anilox rollers have good temperature stability, can maintain good performance in high temperature environments, and are not easy to deform or crack.
