What are the precautions for glass scale clay corrosion protection? The desulfurization tower glass flakes have a short cycle and a relatively low cost. The typical anticorrosive coatings currently used are glass flakes. It is attributed to organic polymers as the matrix, vinyl resin and phenolic epoxy resin. The material is made up of glass flakes with different diameters. It has the characteristics of high temperature resistance, wear resistance and high anti-corrosion effect. Because it has a large expansion coefficient relative to the base materials such as steel and cement, it is in the case of thermal shock. The lower resin layer is easily cracked and dropped, and a thermal stability layer can be formed, thereby preventing cracking and peeling of the substrate.
In summary, the glass flakes anti-corrosion coating is very suitable for anti-corrosion data construction of desulfurization tower. Other desulfurization tower glass flakes are often used in the construction industry. Therefore, in construction and application, we should always summarize the reasons for corrosion, and we should summarize the design during construction. According to Xiaobian, at present, the desulfurization process of incineration coal-fired power plants is mainly based on wet desulfurization, and a small part of seawater desulfurization and dry desulfurization processes are selected. The wet desulfurization process is mainly the gypsum and limestone wet desulfurization process. The main components of the flue gas and the factors that cause the corrosion and damage of the desulfurization tower are many. The chemical gases contained in the flue gas emitted by the square coal-fired power plant, as well as the temperature fluctuation in the tower, etc., all form desulfurization tower corrosion and Damaged elements.
The traditional practice of chimney and tail flue anti-corrosion is to use vinyl ester resin glass flakes or foam glass bricks, which have proved to be unsatisfactory. The main reason for the failure is the temperature resistance of the anti-corrosion material. All epoxy resins are used at temperatures...
·Desulfurization system (scale clay) anti-corrosion program
VEGF scale clay. Relatively speaking, the latter's comprehensive performance includes corrosion resistance and temperature resistance are better than the former. 1. Anti-corrosion mechanism of scale clay The scale clay contains 10%-40% glass flakes with different diameters. After the construction is completed, the flat glass flakes are arranged in parallel in the continuous phase of the resin to form a dense anti-seepage. Layer structure...
