Construction process of anticorrosion ceramic organic coating used for inner wall of desulfurizing tower and inner wall of flue

Abstract

The invention provides a construction process of an anticorrosion ceramic organic coating used for an inner wall of a desulfurizing tower and an inner wall of a flue. The process comprises the following steps of examining the state of a primary surface, treating a welded joint, derusting by sandblasting, examining cleaning and protecting, detecting and confirming by a technical staff, spraying an undercoat, spraying a finishing coat, examining the appearance of a coating and the membrane thickness, conducting electric spark testing, repairing a leaking point, and maintaining. The spraying process improves the construction safety and shortens the construction period, and the comprehensive cost performance ratio of a vinyl glass flake is lower than that of the organic coating. The project changes the corrosion resistance process of the existing desulfurizing tower, the manual blade coating is improved to mechanical spraying, the construction process is high in solid content and environmentally friendly and realizes energy conservation and emission reduction, the construction safety is improved, the construction period is shortened, the degree of innovation of the project is high, the innovations of the performances of corrosion resistance and abrasion resistance of the product and the process route are prominent, the effect of promoting the technical progress of the industry is obvious, the overall technology reaches the domestic advanced level, and the situation that only the vinyl glass flake can be used as the anticorrosion layer in the former application of the industry is changed.

Description

technical field [0001] The invention relates to the technical field of paint spraying technology, in particular to a construction technology of a corrosion-resistant ceramic organic paint for the inner wall of a desulfurization tower and the inner wall of a flue. Background technique [0002] In the prior art, the anti-corrosion lining of the inner wall of the desulfurization tower and the flue is generally glass flakes. Glass-flake mastic resin (Glass-flake mastic resin) is made by adding glass flakes and powder, etc., with resin as the cementing material, and can be scraped Mixed materials for construction. The internal structure of glass flakes is very similar to that of glass fibers. It is made by rapid cooling of molten glass under tension. Because glass flake coating has corrosion resistance, good permeability resistance, low shrinkage rate of coating film, small thermal expansion coefficient, less curing residual stress, wear resistance, simple construction and easy ...

AI Technical Summary

Problems solved by technology

The anticorrosion of glass flakes used in the prior art has great potential safety hazards. At present, the glass flakes we use are flammable in case of fire, causing devastating losses. At present, there have been many major safety accidents in desulfurization towers caused by fires caused by anticorrosion. This technology uses a new type of high corrosion-resistant ceramic organic coating as the anti-corrosion material, which has the characteristics of non-flammability, and fundamentally solves the problem of fire accidents caused by anti-corrosion construction

Moreover, the construction period is long, and construction safety cannot be guaranteed
