Problems solved by technology

At present, pressure gauges are facing many problems during use, among which friction resistance is a problem that many pressure gauges must face and solve. In order to improve the strength, wear resistance and high temperature resistance of pressure gauges, people usually use paint on the surface of pressure gauges. Rapid realization; however, there are still problems in the production of paint, such as: high production cost, short service life, low heat resistance and wear resistance, small adsorption, easy to fall off, little prospect for promotion and application, etc.
