Problems solved by technology

However, in the above production method, the mixing uniformity of the monomer material is poor, and it is difficult to control and adjust. Because acetylene carbon black is used as the semiconducting chain component in the component, its fineness is too fine, the surface adsorption force is too strong, the dispersion is large, and it is easy to absorb. Tide, it is difficult to accurately control the proportion when weighing and mixing, the deviation is large, and it is more difficult to control when firing with protective inert gas nitrogen, and the yield is low

Description

technical field [0001] The invention belongs to the technical field of electronic materials, in particular to a method for preparing a high-power non-inductive synthetic resistor. Background technique [0002] Non-inductive synthetic resistor refers to a resistor whose inductive reactance value is very small and can be ignored. Some precision instrumentation equipment and electronic industrial equipment often need to use this kind of non-inductive synthetic resistor. Non-inductive synthetic resistors are often used as loads to absorb unnecessary electric energy generated during the use of products, or to buffer and brake. Such resistors are often called braking resistors and load resistors. In addition, for high-precision resistors, it is not allowed to have high impedance in the product, which requires the selection of high-quality materials and high-demand processes. Among them, metal non-inductive resistors are the most common. [0003] Metal non-inductive resistors ar...
