High power resistor paste

1、 Overview

High power resistor pasteIt is a new process for manufacturing high-power resistors, which is a resistance paste made by mixing conductive materials with electrical insulation materials. This technology has the advantages of simple process, short production cycle, low cost, long service life, and stable performance.

2、 Preparation process

The preparation process of high-power resistor paste mainly includes the following steps:
1. Raw material preparation
The main raw materials for resistor paste are conductive materials and electrical insulation materials.conducting materialGenerally, metal powders such as copper, silver, nickel, etc. are used; Electrical insulation materials generally use aluminum oxide, silicon dioxide, etc.
2. Mixed preparation
Mix finely processed conductive materials and electrical insulation materials in a certain proportion, add rheology agents, plasticizers, dispersants and other additives, and add an appropriate amount of solvent to make a resistance paste.
3. Drying
After mixing and preparing the resistance paste, it needs to be dried. During the drying process, temperature and humidity should be controlled to ensure that the resistance paste dries evenly and does not produce cracks or deformations.
4. Compression molding
After dryingresistor pasteCompression molding is required, and common molding methods include sheet, cylindrical, spherical, etc. The formed resistor needs to be sintered at high temperature to become an integrated resistor.

3、 Application Fields

High power resistor pasteWidely used in fields such as power, electronics, communication, metallurgy, etc., such as resistors, high-voltage switches, relays, lightning arresters, etc. in power electronic equipment. In addition, it is widely used in fields such as automotive electronics and household appliances.
development trend
With the rapid development of electronics, information technology, energy and other fields, the demand for high-power resistor paste is constantly increasing, and the preparation technology is also constantly improving and perfecting. In the future, high-power resistor paste will be more widely used in various fields and become an emerging industry with broad development prospects.
