Hydraulic steel pipe inner wall ceramic material good in comprehensive performance

Abstract

The invention discloses a hydraulic steel pipe inner wall ceramic material good in comprehensive performance. The hydraulic steel pipe inner wall ceramic material is prepared from, by weight, 54-56 parts of pure aluminum powder, 159-162 parts of iron oxide red, 18-19 parts of cobalt nitrate, 18-19 parts of nickel chloride, 37-38 parts of tetraethyl orthosilicate, 74-76 parts of absolute ethyl alcohol, 10-11.5 parts of nano Y-ZrO2 powder, 8.5-9.5 parts of sodium tetraborate, 2-3 parts of ferromolybdenum powder, 3-4 parts of montmorillonite, 4-5 parts of coal ash, 1-1.3 parts of ammonium chloride, 1.5-2 parts of calcium oxide, 2-3 parts of cuprous oxide and a proper amount of deionized water. According to the hydraulic steel pipe inner wall ceramic material good in comprehensive performance, the proper amount of coal ash is added so as to serve as a component, and the production cost is reduced; in cooperation with adding of the calcium oxide and the cuprous oxide, crystals of the material are further refined; and the ceramic material which is even in organization structure, low in porosity and good in combination with a pipe wall is formed on the inner wall of a hydraulic steel pipe through the self-propagating synthetic technology.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a hydraulic steel pipe inner wall ceramic material with excellent comprehensive performance. Background technique [0002] There are many types of pipelines used in the hydraulic system. According to the working pressure and installation position of the hydraulic system, steel pipes, copper pipes, rubber pipes, nylon pipes and plastic pipes are selected. Once these pipelines are damaged and leak oil, they will pollute the environment, affect the normal function of the system, or endanger safety. The present invention uses hydraulic steel pipes as the research object. When the hydraulic system is working, the hydraulic pipeline has to bear high pressure, coupled with the combined effect of alternating stress caused by pressure instability, vibration stress caused by equipment vibration, assembly stress, etc. , Corrosion points or damages produce stress concentration, and the pip...

Problems solved by technology

However, due to the intense self-propagating reaction, the heat loss during the reaction process is large, and the thickness of the inner wall of the steel pipe is limited by melting, resulting in limited bonding strength and certain pores in the metallurgical bonding part, which affects the heat resistance, corrosion resistance, and Abrasion resistance has a certain influence. Under some high-impact working conditions, the ceramic coating will fall off, which will affect the service life and safety factor of the oil pipe. It needs to be improved on the basis of the original text.
