Can the corrosion of continuous dryer mesh belt be avoided?

- May 03, 2019 -

The anti-corrosion of dryer mesh belt itself refers to the protection of stainless steel. The following is mainly about the protection of stainless steel, and the same is true of mesh belt. I hope that customers will pay attention to it. In order to delay the service life of your mesh belt, the operation status of mesh belt. Crevice corrosion is mainly due to the existence of crevice, which leads to the corrosion of dielectric electrified mesh belt. It is a headache, so we should take good protective measures.

dryer mesh belt itself refers to the protection of stainless steel. The following is mainly about the protection of stainless steel, and the same is true of mesh belt. I hope that customers will pay attention to it. In order to delay the service life of your mesh belt, the operation status of mesh belt. Crevice corrosion is mainly caused by the electrochemical inhomogeneity of the medium due to the existence of crevices. Therefore, for the protection of crevices corrosion, we can mainly refer to the following points:

1, reasonable design to avoid crevices. For example: welding is better than riveting; butt welding is better than lap welding; welding quality must be guaranteed to avoid welding holes; screw joint structure, can use low sulfur rubber gasket, compact filler, joint surface can be protected by coating. In addition, water accumulation area should be avoided in design and diligently cleaned up and dirt removed in maintenance.

p>2. Cathodic protection can be used when the design can not avoid the gap. For example, in seawater, zinc or magnesium poles are sacrificed. But when adopting this method, attention should be paid to the problem of hydrogen embrittlement.

3. Because the corrosion inhibitor is difficult to enter the crevice, it can be coated with corrosion inhibitor paint on the joint surface. For example, for steel, the use of paint with PbCrO4, for aluminium, the use of paint with ZnCrO4; for metal sheets, the use of packaging paper impregnated with vapor corrosion inhibitor can be separated.

4. For some important parts, suitable materials can be used instead, such as stainless steel with high chromium and molybdenum content, which has strong crevice corrosion resistance. The anti-corrosion measures of

dryer mesh belt are the same, which can only be minimized and can not be avoided. The corrosion of dryer mesh belt is a headache, so we should take good protective measures.
