Spraying Research on the Resistive Film of Angular Displacement Sensor Made from Conductive Plastic

Abstract:

Article Preview

The conductive plastic is widely used in making sensitive materials such as angular displacement sensors with high-precision. The resistive film of the sensor is formed by spraying and its quality has a close relationship with the resistance liquid’ density, spraying pressure and time, and drying temperature and time. We draw a conclusion from experiments that for the conductive plastic with carbon fillers, the optimal linearity is obtained under a pressure of 0.5-0.6Mpa in 6-8 seconds and the best abrasion resistance is obtained at a drying temperature of 175°C in 4 minutes when the liquid resistance contains 15% carbon. While for the conductive plastics with metal fillers, the optimal linearity is obtained under a pressure of 0.7-0.8Mpa in 5-6 seconds, and the best abrasion resistance is obtained at a drying temperature of 165°C in 4 minutes when the liquid resistance contains 6% metal fillers. The research results have some guiding significance in improving performance and lowering cost.
