What if the metal rusts after the drying equipment works for a long time?

Because most of the common raw materials ofleather dryerequipment are steel, it is very easy to rust under the condition of long-term application. For the drying equipment that often solves the corrosion of raw materials, it is necessary to do a good job in anti-corrosion. Generally, it is composed of cylinder sections, tablet computers and weldments. Different parts have different main purposes, and their anti-corrosion methods are not the same.

First, paint the rusted parts: if it is found that the whole fuselage is rusted, it can be painted again, which is also an immediate antirust treatment. At the same time, it can also paint part of the drying equipment on time, which can not only maintain the beautiful and generous surface of the overall fuselage, but also improve the service life of the fuselage.

Second, martensitic nickel clad stainless steel plate shall be used for welding at the welding place. Many parts of the three cylinder dryer equipment need to be welded. Cracking and etching often occur when welding with old raw materials, which is very harmful to the service life of the drying equipment. However, the difference between martensitic nickel clad stainless steel plate and carbon structural steel depends on the characteristics of poor heat transfer, large coefficient of thermal expansion and high resistance during heating. With this characteristic, it is necessary to use this kind of raw materials for welding, and other methods shall be selected. However, the corrosion resistance of this kind of stainless steel plate is very good.

Third, apply antirust agent to the leather dryer equipment: when the machinery and equipment leave the factory, all components have been wiped with antirust agent, but there will be some damage after application for a period of time. If the rusted parts need to be cleaned first. Apply antirust agent again.

Fourth, passivation treatment and phosphating treatment are used for machinery and equipment. In production, many spare parts are made of carbon steel. If you work for a long time, it is very easy to turn into a lot of rust on the surface, and you often need to carry out a lot of manual antirust treatment, which will improve the amount of labor. However, passivation treatment and phosphating treatment are mainly based on electricity and electrochemical corrosion, which can expose the original color of metal materials on the surface of rusty steel parts. At the same time, they will continue to be transformed into a solid antirust treatment layer on the surface of metal materials. After the application of this method, even if the dryer equipment is placed in the wet and cold natural environment, it is not easy to rust. The application of this kind of method is very simple, which can not only save a lot of financial and material resources, but also reduce the customer's project investment. Passivation treatment and phosphating anti-corrosion method is an applied and common anti-corrosion method.
