The sewage corrosion process mechanism is very complex. It is variable with the sewage composition and water temperature. The corrosion grade is also different with the content percentage of harmful substances in sewage. Therefore, it’s essential to understand the composition of sewage then completely solve corrosion problems to protect the concrete pool structure and its equipment. Sewage treatment consist three main methods of physical, chemical and biological process that are using a variety of technical procedure to separate the pollutants from wastewater, and convert it into harmless substances then purified. Irrespective of which treatment be choosing, the anticorrosion of sewage pool and equipment is very important. So choose an effective anticorrosion coating is most critical. The sewage treatment pool anticorrosion waterproof coating developed by SWD Urethane Co., USA is the mature products used for many years in the US market. It performed far superior effective over the domestic modified tar asphalt antisepsis coating series. It is able to extend the life of pool to more than 30 years.
2. Characteristics
SWD sewage treatment pool anticorrosion waterproof coating is one component moisture cure environmental friendly hand brushable polyurea urethane products. It’s very stable in contact with corrosion medium such as various industry sewage and waste gases without be dissolution, swelling or decomposition. It will not react with the media to generate new hazardous substances. Coating is dense, flexible, with high adhesive strength on substrate, excellent penetration resistance, able to effectively prevent various liquid and gas penetration. With high erosion resistance, impact resistance, anti-aging performances, the coating ensures that the sewage pool has no crack, damage, peel, pulverization, etc. within its life period.
