Hydraulic steel pipe ceramic lining material excellent in wear resistance and corrosion resistance

Abstract

The invention discloses a hydraulic steel pipe ceramic lining material excellent in wear resistance and corrosion resistance. The 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 ethyl silicate, 74-76 parts of anhydrous alcohol, 10-11.5 parts of nano Y-ZrO2 powder, 8.5-9.5 parts of sodium tetraborate, 3-4 parts of silicon carbide, 2-3 parts of magnesium chloride, 0.8-1 part of ammonium polyacrylate, 4-5 parts of barium titanate, 4-5 parts of alumina fiber and a proper amount of deionized water. Ingredients like barium titanate, magnesium chloride and alumina fiber are added, and a compact coating can be obtained through thermit reaction, so that strength and wear resistance of the material are enhanced further, porosity is lowered, permeability of corrosive atmosphere is lowered, and binding strength, corrosion resistance and wear resistance of the material with a pipe base material are improved. A hydraulic steel pipe made by using the material has good wear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a hydraulic steel pipe ceramic lining material with excellent wear resistance and anticorrosion 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 concentrat...

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.
