HTEE series special infrared radiation coating for high temperature kiln

Abstract

The invention relates to an HTEE series nocturnal radiation paint which is a special energy-saving material for a high temperature furnace and is applicable to petrochemical engineering furnaces and furnaces in the metallurgic, electric power, ceramic, architectural and aviatic industries and other industries, as well as civil furnaces. The invention utilizes a Y2O3 rare-earth nanophase material for enhancing the strength and the aging resistance performance of nocturnal radiation paint and provides a high temperature nocturnal radiation paint which is directly coated on the lining of a metal heating device or on a heater or a fire-resistant ceramic material of the high temperature furnace. The high temperature radiation paint has the advantages of high thermal efficiency, high temperature resistance, stable adhesive property, capability of effectively saving energy, furnace-body service life prolonging, and the like. The invention adopts the hydro-thermal method to synthesize the Y2O3 rare-earth nanophase material, the solid material of the high temperature paint is selected to comprise 50% of zirconia, 20% of monox, 8-15% of aluminum oxide, 3-6% of ferric oxide, 10-14% of chromium trioxide, 3-9% of sodium sodium phosphate and 1-3% of calcium carbonate. A corresponding liquid material (adhesive agent) is a special high temperature adhesive agent and mainly comprises 0.5-3% of Y2O3, 2-6% of aluminum oxide, 1-3% of ferric oxide, 0.4-2% of manganese oxide, 1-3% of calcium carbonate, and the balance of tap water. The ratio of the solid material and the liquid material is maintained to be 3:2. The solid material and the liquid material are proportionally mixed and then evenly stirred at the normal temperature, and then the special nocturnal radiation paint for the high temperature furnace can be obtained. The use temperature of the nocturnal radiation paint ranges from 1,200 DEG C to 1,800 DEG C.

Description

technical field [0001] The invention belongs to infrared radiation paint for high-temperature kilns, which can be used in petroleum, chemical industry, metallurgy, electric power, ceramics, construction, aviation, other industries and civil kilns. Background technique [0002] At present, in the field of high-temperature kiln technology, infrared radiation technology has been used to produce heating equipment. Since infrared electromagnetic waves can be absorbed by objects, the internal particles of the substance will resonate, so that the characteristics of the temperature rise of the object can be fully utilized. Depending on the material, molecular structure and temperature of the radiant, its radiation wavelength is also different. This property provides a variety of radiant coatings for the production of heating equipment to a great extent. Spraying infrared radiation paint on the inner wall of the industrial kiln can improve the blackness of the inner wall of the kiln,...
