Problems solved by technology

Due to the limitation and characteristics of the composition, this kind of far-infrared reflective layer has poor high temperature resistance, poor wear resistance, and poor anti-sticking properties. It is not suitable for use in high temperature, impact, and friction dynamic environments, especially it is easy to cause adhesion of molten materials. thus limiting its use

Abstract

The invention provides a high temperature resistance infrared radiation pottery dope, which belongs to the thermal engineering field. The dope is a mixture of the following materials in mass share: 200 mesh zirconium dioxide 10, 200 mesh zircon quartz sand 20, 300 mesh feldspar 10, 300 mesh cerium oxide 7, 300 mesh manganese sesquioxide 15, 300 mesh manganic oxide 3, 600 mesh titanium dioxide 2, 200 mesh alumina 10, 400 mesh graphite 10, 400 mesh boron nitride 3 and 200 mesh carborundum 10. The graphite and boron nitride in the dope are of lubricating and anti-bonding functions, the carborundum is of wear resistance function, the manganic oxide, titanium dioxide and alumina are of strong infrared ray emission and the dope mad of zirconium dioxide, zircon quartz, feldspar and cerium oxide has good compact structure and strong fire-proof and the manganese sesquioxide can catalyze C, S and N for conversion. Therefore, the invention is applicable for use in dynamic furnaces such as coal dust furnace, boiling furnace and fluidized bed furnace.

Description

technical field [0001] The invention proposes a high-temperature and far-infrared radiation-resistant ceramic coating used for coating a substrate in the thermal engineering field. Background technique [0002] Before the present invention is proposed, I have filed a patent application for the invention of a coal-fired kiln and coal-fired additive. In the patent application document, a far-infrared reflective layer is disclosed, and its composition is as follows: Spar powder 5-10, cobalt oxide 3-7, stealite 2-4, titanium dioxide 3-6, silicon fluoride 5-9, zirconium dioxide 10-20, chromium oxide 10-30, cerium oxide 4-8, kaolin 5-9, 0.5-1.5 parts of aluminum trihydride adhesive, 10-30 parts of graphite and 4-6 parts of boron nitride. Due to the limitations and characteristics of the composition, this far-infrared reflective layer has poor high temperature resistance, poor wear resistance, and poor anti-stickiness. Thus limiting its scope of use. SUMMARY OF THE INVENTION ...
