Problems solved by technology

The alkaline sulfur-containing sewage has complex corrosion characteristics, which not only severely corrodes the steel, but also greatly damages the anti-corrosion coating used on the tank wall, thereby reducing the service life of the anti-corrosion coating
The problem of anti-corrosion paint falling off in storage tanks is a potential safety hazard in alkaline water storage tanks and other equipment, and it is also a bottleneck restricting the long-term operation of devices. It has become a major issue in alkaline water treatment in the field of coal-to-oil chemical industry. Development of new anti-corrosion coatings for protection

Abstract

The invention relates to an anti-corrosion coating, which contains the following components: organic silicon modified epoxy resin, bisphenol F epoxy resin, solvents, carbon black, dispersing agents, glass flakes and auxiliaries. Compared with an alkaline sulfur-containing sewage storage tank coated with the existing anti-corrosion coating special for the sewage storage tank, operation period of an alkaline sulfur-containing sewage storage tank coated with the anti-corrosion coating is remarkably prolonged for more than half a year, and compared with other existing anti-corrosion coatings, the anti-corrosion coating does not fall off in at least one and a half years, and therefore the anti-corrosion coating can be suitable for alkaline sulfur-containing sewage media of coal direct liquefying process. In addition, the invention further relates to a preparing method and a use method of the anti-corrosion coating.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to an anti-corrosion coating suitable for the inner surface of an alkaline sewage storage tank in a coal direct liquefaction process. The invention also relates to a preparation method and a use method of the anticorrosion paint. Background technique [0002] Shenhua Group Ordos Coal-to-Liquid Company has the world's first large-scale industrialized coal direct liquefaction to produce oil production equipment. Coal direct liquefaction technology has attracted worldwide attention in recent years. However, the alkaline sulfur-containing sewage produced by the direct coal liquefaction process is quite special. The operating conditions of the process are: working temperature ≤ 50°C, the composition of alkaline sewage: sulfide, ammonia, volatile phenol, condensate oil (the maximum content of sulfide is 9000mg / L, the highest ammonia content is 28000mg / L, the condensate oil contains a certai...
