Application of Supersonic Spraying in Papermaking and Printing Industry

       

Application of sub-supersonic spraying in papermaking and printing industry At present, supersonic spraying calender rolls are used in the printing industry, which can withstand the rolling pressure of the calender rolls, the coating is dense, and can be ground to a mirror surface, which is better than chilled cast iron. Excellent wear resistance, the coating also has high rolling contact fatigue strength.

Corrosion resistance is also better than electroplated roll surface. The WC coating can be sprayed on the surface of the carbon steel roll, which is especially suitable for the manufacture of super large calender rolls without casting defects of chilled cast iron. In addition, the coating can also be sprayed on the surface of the dehydration box panel, with a thickness of only 0.15mm. The abrasiveness is enough to beat stainless steel dozens of times.

 

At present, the world's top printing equipment manufacturers have begun to formally put into use. The experimental results have proved that its wear resistance and corrosion resistance have been greatly improved, and the service life has been effectively improved. The supersonic spraying technology is developed through the introduction of advanced equipment and technology. The new technology of metal thermal spraying has greatly improved the benefits of many printing companies.
