What are the key points of anti-corrosion in sewage pool?

As an important facility for treating domestic sewage and industrial wastewater, the anti-corrosion work of sewage tank is particularly important. The following are the main points of anti-corrosion of sewage pool:

One: Choose the right paint.

When selecting coatings, we should choose suitable coatings according to the nature, temperature, pressure and other factors of sewage. Generally speaking, epoxy resin, polyurethane, glass flake cement/coating and other materials have good corrosion resistance and chemical resistance, which can be given priority.

Second: surface treatment

The surface treatment of sewage pool is very important. Before painting, the sewage tank must be thoroughly cleaned, derusted, polished and other surface treatments to ensure the close combination of the coating and the substrate and achieve the best anti-corrosion effect.

Three: coating construction technology

Multi-layer coating method should be adopted to enhance the anticorrosion performance of the coating. Sufficient drying time should be left between the coatings to ensure the firmness of the coatings. In addition, the interior of the sewage tank should be sprayed or brushed to ensure uniform coating, no bubbles and no pores.

Four: Regular maintenance

It is very important to maintain the sewage tank regularly. Regularly check whether the coating falls off, discolors and cracks, and repair and replace it in time. At the same time, it is necessary to clean up the sediment in the sewage pool regularly to reduce the corrosion and erosion of chemicals.

In a word, in order to effectively improve the durability and service life of sewage tanks, it is necessary to select suitable coatings, carry out surface treatment, master the coating construction technology and maintain them regularly.
