Spraying Research on the Resistive Film of Angular Displacement Sensor Made from Conductive Plastic
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℃ 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℃ in 4 minutes when the liquid resistance contains 6% metal fillers.The research results have some guiding significance in improving performance and lowering cost.
