Abstract

The invention discloses a graphene-enhanced ceramic lining material for a hydraulic steel tube. The graphene-enhanced ceramic lining material is prepared from the following raw materials in parts by weight: 54-56 parts of pure aluminium powder, 159-162 parts of iron oxide red, 18-19 parts of cobalt nitrate, 18-19 parts of nickel chloride, 37-38 parts of tetraethoxysilane, 74-76 parts of absolute ethyl alcohol, 10-11.5 parts of nanometre Y-ZrO2 powder, 8.5-9.5 parts of sodium tetraborate, 7-8 parts of graphene, 1.5-2 parts of cerous fluoride, 4-5 parts of lanthanum oxide powder, 1.5-2 parts of lithium carbonate, 0.6-0.7 part of alcohol amine chelated titanate, and deionized water. According to the graphene-enhanced ceramic lining material disclosed by the invention, graphene can be uniformly dispersed in the material during a preparation process of carrying out surface modification on the graphene and then adding the graphene in the material, is uniform in structure and capable of enhancing the strength of the material, and high in bonding strength with a matrix material of the tube and not liable to crack and fall off; and moreover, the process is convenient for industrial control, high in efficiency, and energy-saving and consumption-reducing.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a graphene-reinforced ceramic lining material for hydraulic steel pipes. 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 pipelines are fatigued ...

AI Technical Summary

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.
