In recent years, with the rapid development of the radio industry, from household televisions, tape recorders, audio equipment to electrical equipment and other electrical instruments used in the industrial sector, it is necessary to use grease to lubricate these electrical contact parts, such as television tuner, Key switch, volume, etc. of the radio recorder.
In addition to general grease performance, grease for electronic parts also requires lubricity and electrical performance to improve direct reliability and extend the life of the entire device. Potentiometer grease is mainly used for the lubrication and damping of the rotary shaft and the shaft sleeve of the potentiometer. Its use characteristics are as follows:
(1) Lubrication, which produces relative displacement and friction between rotary or direct-acting potentiometers or variable capacity parts. The main function of grease is to solve the friction between electronic components and reduce friction and wear
(2) On the basis of ensuring lubrication, the damping effect and potentiometer grease has good damping and accurate positioning, ensuring that the positioning is not affected by micro-vibration and collision. Otherwise, the brightness of the TV and radio will suddenly dim, and the sound will suddenly decrease, which will affect the viewing effect. In order to ensure stability, the static friction coefficient of the grease is required to be small and the dynamic friction coefficient is large.
(3) High and low temperature adaptability, stable contact resistance;
(4) The colloid has good stability, no oil separation, no evaporation, no pollution to electronic parts during use
(5) Protective function to prevent metal corrosion at the place of use and protect the body from rust.
Potentiometer grease ensures the damping and lubrication of the shaft and sleeve, clear sound and image, prevents noise, and maintains a good use effect for a long time.
