Dust remover flue gas anti-corrosion paint Winter maintenance anti-corrosion paint

Product description

Product composition and characteristics This product is made of PTFE ethylene It is a film-forming solution, with barite, flake graphene, etc filler 。 After curing, the coating has high inertia, high density and temperature resistance up to 250 ℃.

Working mechanism coating After the medium film forming solution and inorganic filler are mixed and solidified, the polytetrafluoroethylene is relatively stable, is not easy to lose electrons, and has good swelling resistance. Barite, graphene and other materials have good chemical stability and high hardness in the coating. Smaller particle size can also form a dense film in the film forming solution.

 The main reason for the corrosion of the filter bag of the bag type dust collector is that the waste gas contains acid and alkaline components, and the dew point changes with the concentration of these chemical gases. If the dust collector is started or stopped below the dew point, in addition to the water vapor condensation that causes the bag pasting SO2 Formed in contact with water H2SO2 The fiber of the filter bag will be deformed, thus losing the strength. At this time, Zhisheng Weihua Anticorrosive coating Relevant people proposed that acid and alkali resistant filter bags should be used to prevent the corrosion of the bag type dust collector, and the inlet air of the dust collector should be The Conduit The shell shall be well insulated, and the precipitator can be heated if conditions permit. The following are some reasons for the corrosion of the bag type dust remover, which can be summarized for your understanding of the corrosion of the dust remover.

 ①、 Reduce the moisture content in the flue gas. To reduce the dew point temperature of the gas, it is necessary to reduce the moisture content in the gas. For example, the wet kiln should try to reduce the moisture content of the slurry, and try to increase the temperature of the gas, so as to increase the temperature difference between the gas temperature and the dew point temperature. The bag type dust remover produces dew point corrosion, and the waste gas from the normal coal-fired boiler needs to be painted ZS-1041 The flue gas anti-corrosion coating is used as the anti-corrosion coating. If it is hazardous waste and waste gas generated by waste burning boiler, the bag filter is used for anti-corrosion ZS-1032 Strong oxidation resistant anticorrosive coating, and resistance to the corrosion and immersion of dioxin and other strong corrosive media. 　　

 ②、 Reduce the air leakage rate of the bag type dust collector. Air leakage is one of the main reasons for the corrosion of the dust collector. The air leakage rate is closely related to the negative pressure in the dust collector. The greater the negative pressure, the more serious the air leakage will be.

 ③ Strengthen the sealing of the dedusting system. This measure includes the sealing of the deduster itself and other equipment and pipes in the dedusting system. If the sealing is poor, a large amount of cold air will leak into the system.

④ . Try to reduce the number of times when the host starts and stops and the precipitator interrupts electricity and power supply, especially the dryer, which has a large production capacity and has to run intermittently. Some cement plant dryers need to dry a variety of materials in turn, which increases the number of starts and stops. Due to frequent startup and shutdown, the gas temperature in the precipitator drops below the dew point more than once a day.
