Long-term corrosion protection of inner wall of sulfuric acid storage tank

Corrosion protection outside sulfuric acid tank in fluorine chemical industry or sulfuric acid plant is also a headache for chemical enterprises. The gas discharged from the breathing valve of sulfuric acid tank and acid rain caused by rain are more corrosive, and the conventional coatings with good corrosion resistance in the market are about 1-2 years. Dilin 441 waxy heavy-duty anticorrosive coating is a good solution in marine and chemical heavy-duty anticorrosive environments because of its strong acid and alkali resistance, strong adhesion and high density. It has simple coating, good anticorrosive performance and zero VOC emission. It only needs to be polished and cleaned before painting Dilin 441 coating during construction, which can meet the normal application for more than 5-10 years. Dilin 482 metal accelerator and Dilin 441 waxy heavy-duty anticorrosive coating are particularly good in corrosion resistance and ductility in metal sewage tanks.
