Basic requirements for production process of electrode paste

Detailed description of electrode paste material and equipment requirements

Electrode paste as a kind of carbon material, its production technology and other carbon material preparation technology is similar to a small difference, this paper mainly focuses on the production process of electrode paste, the material and equipment a

 electrode paste as a kind of carbon materials, the production technology and other carbon material preparation was the same, there are mainly raw material calcined, crushing, screening, grinding, kneading and forming a few kinds of electrode paste is self baking electrode materials, the roasting stage in -arc furnace operation, so the production process do not include roasting and after graphitization process.

 Basic requirements for raw materials and equipment

1) strictly control the ash content and resistivity index of raw materials, ensure the testing of cars and cars, return unqualified raw materials resolutely, and ensure the use of high-quality raw materials;

2) storage of different raw materials in the warehouse, strict management, no mixing with other materials:

3) the residue is strictly screened to ensure the removal of electrolytes and fine powder with high ash content;

4) powder material to ensure fineness and purity, closed management, to prevent dust pollution;

5) stabilize the asphalt index, use liquid asphalt, and control the thermal insulation temperature;

6) high-efficiency, energy-saving and easy to maintain jaw crusher for intermediate crushing, ball mill for grinding, vibrating screen for raw material screening;

7) adopt PLC computer control system for precise batching to eliminate batching errors;

8) the two-axis stirring kneader is used for mixing and kneading, and the mixing knife crosses the radius, so that the paste is fully mixed and evenly:

9) heat transfer oil heating boiler for kneading pot to improve thermal efficiency and thermal stability:

10) the use status of each production equipment should be checked regularly, and the equipment should be repaired or replaced in a timely manner.
