What are the key points of the coating technology of mixed base carbon strip?

The coating technology of mixed base carbon tape is one of the key links in the production of thermal transfer carbon tape, and its key points include the following aspects:

1. Coating preparation

High-volume, continuous and stable preparation of high-quality coatings: coating preparation usually includes feeding, dissolution, dispersion, grinding, testing, transportation and other processes. This is the basis of mixed base carbon strip coating, and the quality of the coating directly affects the subsequent coating effect and the final performance of the carbon strip.

Technical difficulties: mainly reflected in the selection, structural design and function optimization of chemical kettle, dispersion kettle and grinding equipment, so as to match the coating characteristics of different products and different coatings, and meet the diversified requirements of technical indicators such as coating particle size, viscosity and solid content of product production.

2. Coating process

Coating method: The coating of the mixed base carbon belt needs to transport the coating of each carbon belt coating to the coating machine, according to the specific process parameters, respectively, on both sides of the base film. The choice of coating method directly affects the uniformity and thickness of the coating.

Oven heating: the carbon belt after coating needs to be dried, and factors such as oven heating mode, oven length, inlet and exhaust air volume are closely related to product characteristics and production efficiency.

Process environment control: process environment parameters such as temperature and humidity have an important impact on product quality and need to be strictly controlled.

3. Eliminate static electricity

Research and combined application of a variety of electrostatic elimination methods: in the coating process, the generation of static electricity may affect the uniformity of the coating and the performance of the carbon strip, so it is necessary to effectively control static electricity through the research and combined application of a variety of electrostatic elimination methods.

4. Tension control

The matching of tension parameters with different product characteristics: The control of tension during the coating process is crucial for the stability of the coating and the flatness of the carbon strip, and the appropriate tension parameters need to be set according to the production requirements of different products.

5. Quality control and defect elimination

Coating quality monitoring and coating defect elimination measures: Through advanced testing equipment and technical means to real-time monitoring of coating quality, timely detection and elimination of coating defects, to ensure the quality of carbon strip stability.

6. Automatic control

Research and application of automatic control technology: With the development of science and technology, automatic control is more and more widely used in mixed base carbon strip coating. By means of automatic control technology, the coating efficiency and process stability are improved, and the influence of human factors on product quality is reduced.

In summary, the coating technology of the mixed base carbon strip involves many aspects such as coating preparation, coating process, electrostatic elimination, tension control, quality monitoring, defect elimination and automatic control. The effective implementation and control of these key points are of great significance for improving the quality and performance of the mixed base carbon strip.
