The corrugating roller of the corrugating machine is the forming mold of the corrugated cardboard, which is an expensive and important part of the single-sided corrugating machine. The height of the corrugated teeth determines the forming thickness of the corrugated cardboard and the strength of the corrugated cardboard. Therefore, only when the corrugating roller of the corrugating machine achieves the effect of high wear resistance and not easy to deform, can the produced corrugated cardboard meet the requirements of forming quality. In the past, after the surface of the corrugating roller of the corrugating machine was worn out, the traditional repair method was to use the ordinary hard chrome process to treat the surface, and its wear resistance was not ideal.
And the corrugating roller of the corrugating machine using the silicon carbide-chromium nano-ceramic coating, its innovative processing technology is: the working surface of the corrugating roller substrate of the corrugating machine has a silicon carbide-chromium nano-ceramic coating with a thickness of 0.08-0.10mm, and the silicon carbide -The chromium nano-ceramic coating consists of three layers, the layer is an ion diffusion layer that is firmly bonded to the corrugating roller substrate of the corrugating machine, the second layer is the bottom layer combined with the layer, and the outer layer is silicon carbide-chromium nano-layer combined with the bottom layer. Ceramic coating. The characteristics of this process are: the corrugating roller of this type of corrugating machine has about 3 times higher wear resistance than the corrugating roller of the original hard chrome plated corrugating machine, which can better improve the life of the corrugating roller of the corrugating machine and reduce the downtime for overhaul. time, so that the production cost is greatly reduced. The anilox roller is a key component of flexographic printing, how its performance directly affects the printing quality of the product.
The traditional metal anilox roller of flexographic printing machine is generally made of mild steel or copper, and the ink hole is electronically engraved into a 45° pyramid structure, and then chrome-plated. This kind of roller is easy to wear due to the thin coating, especially if the scraper type inking device is used, it is more likely to wear and reduce the cell volume, which affects the printing quality of the product. The laser-engraved nano-ceramic anilox roller is made of nano-ceramic materials, so that its strength, toughness, wear resistance, etc. have been significantly improved. Therefore, laser-engraved ceramic anilox rollers have been widely used in flexo plates. On the printing press, metal anilox rolls with poor performance will gradually be replaced by ceramic anilox rolls with excellent performance. The characteristics of nanometer can meet the requirements of greatly improving the hardness, toughness and wear resistance of ceramics, which provides a reliable technical guarantee for the well-made anilox roller, and also lays a solid foundation for improving the printing quality of the carton.
