Problems solved by technology

The pressure gauge casing is an important part of the pressure gauge. It is the carrier for the fixed placement of each part. It is mostly made of metal. Because the surface of the metal is relatively active, it is prone to rust when used in the atmosphere or in corrosive media. Then it affects the overall quality of use and life, and this problem needs to be improved and solved
[0003] At present, it is mostly solved by coating, but the quality of most coatings is average, and the effect of use is ordinary, which needs continuous improvement

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-stability anticorrosion coating for pressure gauge casings and a preparation method thereof. Background technique [0002] Pressure gauge (English name: pressuregauge) refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used and it is used in almost all industrial processes and scientific research fields. It can be seen everywhere in heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle repair and maintenance factory and shop. Especially in the process of industrial process control and technical measurement, due to the high mechanical strength and convenient production of the elastic sensitive components of mechanical pressure gauges, mechanical pressure gauges are more and more widely used. The pressure gauge casing is an importa...
