Glazing Dryer
Glazing dryer, is used for special paper machines and other models under specific working conditions. It is generally large, which is not conducive to transportation, and has very high technical requirements. Traditional glazing dryer are made of cast iron, but with the continuous development of welding technology and metal spraying technology, the industry gradually agrees that steel cylinders have more advantages, are safer and more reliable, can save steam consumption, and greatly reduce production costs.
However, glazing dryer spraying has very high requirements for spraying equipment, technology, and operator experience. The coating needs to have sufficient hardness to ensure wear resistance, and at the same time requires a very low finish to achieve good paper surface uniformity. decoration effect.
We have inported advanced spraying equipment since 2016, using its own spraying technology accumulation to successfully break through such industrial problems, exceeding the technical level of the same industry and even foreign companies. Based on the spraying equipment with higher speed and higher combustion temperature, the hardness of the coating after spraying can reach HV1000, and the smoothness can reach 0.06um.
Because the hardness of the sprayed layer is much higher than that of the original cast iron and steel cylinder surface, it has good anti-wear performance and can maintain a low surface roughness for a long time. The ceramic material contained in the spray coating itself has anti-sticking properties, which can keep the cylinder surface clean during the application process, and with its own low smoothness, it can achieve a better finishing effect on the paper surface. Combined with the coating itself, the glazing dryer can maintain a good working condition for a long time, which greatly improves the efficiency of the paper machine operation.
We have very rich experience in spraying glazing dryer and has successfully completed more than ten glazing dryers have been sprayed on-site, and the current results are good, and have won unanimous praise from customers.
