Power plant boiler desulfurization and denitrification long-life self-cleaning section steel bottom surface primary glaze

Abstract

The invention relates to a power plant boiler desulfurization and denitrification long-life self-cleaning section steel bottom surface primary glaze which comprises the following components in percentage by weight: 55-90% of a main material, and 10-45% of an auxiliary material, the main material comprises the following components in percentage by weight: 50-60 percent of at least one of quartz sand or zircon sand, 10-30 percent of at least one of Fe3Al, FeAl, Fe2Al5 and FeAl3, and 3.2 to 5.2 percent of lithium nickelate; the auxiliary material comprises the following components in percentage by weight: 9.5-11.5 percent of sodium carbonate, 10.22 -12.25 percent of borax, 1-1.6 percent of ice crystal, 5-8 percent of titanium dioxide, 0.3-0.35 percent of manganese oxide, 0.56-0.8 percent of ferric oxide, 1.2-2.6 percent of calcium carbonate, 1-1.6 percent of magnesium carbonate and 0.8-1.2 percent of zinc oxide. According to the power plant boiler desulfurization and denitrification long-life self-cleaning section steel bottom surface primary glaze, fire-resistant and antioxidant components are added so that high-temperature resistance and corrosion resistance are obtained.

Description

technical field [0001] The invention relates to a desulfurization and denitrification long-life self-cleaning primary glaze on the bottom surface of a power plant boiler, which has the functions of high temperature resistance, corrosion resistance and self-cleaning, and belongs to the technical field of enamel glazes. Background technique [0002] Enamel glaze (enamel glaze) is used to enamel on the metal body, which can be firmly combined with the body after firing, and has a protective and decorative effect on the body. After the enamel is coated on the metal body, it forms an alkali-boron-silicate glassy substance; the conventional enamel has insufficient high temperature resistance and anti-corrosion performance, so it cannot be applied in some specific fields. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a desulfurization and denitrification long-life self-cleaning steel bottom primary glaze...
