High-temperature anti-carburization anticorrosion infrared radiation glaze materials and method for preparing same

Abstract

The invention discloses a high temperature carbon-seepage-resistant corrosion prevention infrared radiation frit and preparing method, which comprises the following parts: 8-43% anticlinanthous plate, 10-17% simple frit, 10-17% enamel powder, 20-28% chrome green, 3-6% lower-guide-powder, 7-12% cordierite and 7-15% high emissivity material. The preparing method comprises the following steps: mixing up the above materials in the range of value and crushing; milling ball for two to three hours; filtering the mill-ball; stewing the mill-ball for 45 to 70 minutes and detaching the mill-ball liquid; drying the ball mill wet material at the temperature between 130deg.c and 200 deg.c; rolling for thin and riddling; preparing the 280-320 order bone mea. Preparing one kilo 600-800ml adhesive of high temperature infrared radiation frit and bone powder.

Description

technical field [0001] The invention relates to a high-temperature infrared radiation enamel glaze, especially a high-temperature anti-carburization and corrosion-resistant infrared radiation glaze with high emissivity in the full infrared band and its preparation, which is sintered on a heat-resistant metal heating body at 850-1200°C method. Background technique [0002] In recent years, various low and medium temperature infrared radiation glaze materials have been developed rapidly. For example, the Chinese Patent Publication No. CN1463940A "High Radiation Far Infrared Sintering Glaze" discloses a component and parts by weight of frit 40-90 , silicon carbide 0-10, calcined sand 2-12 and its oxide with infrared radiation performance 5-30, clay 3-15. Although it has strong radiation ability, is easy to sinter and is not easy to fall off, it has disadvantages: the use temperature is below 850°C, and the high infrared radiation area is limited to the 8-25μm far-infrared band...

AI Technical Summary

Problems solved by technology

Although it has strong radiation ability, is easy to sinter and is not easy to fall off, it has disadvantages: the use temperature is below 850°C, and the high infrared radiation area is limited to the 8-25μm far-infrared band, which is not conducive to radiation heat transfer at high temperatures

[0003] The high-temperature enamel coating technology introduced by the Ministry of Aviation Industry of my country from the former Soviet Union has finalized three products such as W-2, T-1 and B-1000 after years of experimental research by the Aeronautical Materials Research Institute. Its disadvantage: the substrate can only be nickel Cobalt alloy, the process is strict, and must be prepared in special equipment; it cannot be applied to civilian products

[0004] The high-temperature glazes released by the United States, Japan, South Korea and other countries, such as NBSA-19, etc., although the use temperature reaches 1000 ° C, are expensive, do not have high radiation function, and contain metal elements harmful to human body beryllium
