1. What materials are used in the production of cement fixed resistors?
2. What is the process of manufacturing cement fixed resistors?
3. How are the characteristics of cement fixed resistors controlled during production?
Cement fixed resistors are typically made using a ceramic core coated with a mixture of carbon black and a binder, such as clay or cement. The resistance value is determined by the length and diameter of the resistive element.
The production process begins with mixing the carbon black and binder to form a paste, which is then applied onto the ceramic core. The resistive element is then shaped and allowed to dry before being heated in a kiln to cure the coating and ensure good adhesion to the core.
To control the characteristics of cement fixed resistors, manufacturers carefully monitor the composition of the resistive element, the thickness of the coating, and the curing temperature. This ensures that the resistors have the desired resistance value, power rating, and stability under varying environmental conditions. Additionally, quality control tests are carried out on samples from each production batch to verify their performance before being released to the market.
