Description

A kind of desulfurization chimney anticorrosion paint and preparation method thereof

technical field

The invention relates to an anti-corrosion coating and a preparation method thereof, in particular to a desulfurization chimney anti-corrosion coating and a preparation method thereof.

Background technique

As the country strengthens the supervision and control of air pollutants, the emission of sulfide in the power industry has been strictly limited, and flue gas desulfurization has become a consensus. At present, after domestic power plants generally adopt wet desulfurization technology, severe corrosion occurs especially in desulfurization chimneys without GGH. In order to prevent corrosion, coating anticorrosion is the best choice in terms of economy and feasibility. At present, most of the desulfurization chimneys that use acid-resistant cement, VEGF scale cement, polyurea coating and polyurethane coating for anti-corrosion have various failure cases. This is mainly because the special working conditions of power plant chimney operation (such as long-term immersion in acidic medium, intermittent high and low temperature impact of 50 ° C to 200 ° C) have higher performance requirements for anti-corrosion coatings. Therefore, conventional heavy-duty anti-corrosion coatings are not necessarily suitable for chimney anti-corrosion after desulfurization. Therefore, it is very important for the safe and environment-friendly operation of power plants to develop a kind of coating that is specially designed for desulfurization chimney anticorrosion and is convenient for construction.
