How is the coating for enhancing wax based carbon ribbon made?

The coating production of enhanced wax based carbon ribbon is a complex chemical process, mainly including the following steps:

1、 Prepare substrate

Firstly, it is necessary to prepare high-quality base film as the substrate for carbon ribbon. Polyester (PET) film is usually chosen because it has excellent mechanical strength and thermal stability, which can meet the performance requirements of carbon ribbon during the printing process.

2、 Make back coating

Solution preparation: Add a certain proportion of silicone resin to the solvent, heat and stir to fully dissolve it, and form a uniform solution.

Immersion of substrate: Immerse the substrate in a prepared solution to evenly coat the surface of the substrate with a layer of resin solution.

Curing and drying: Take out the impregnated substrate and bake it at high temperature to cure the silicone resin and form the back coating of the substrate. The back coating mainly plays a role in enhancing the strength of the substrate, improving wear resistance, and anti-static performance.

3、 Produce release coating

Solution preparation: Add polyester resin to a solvent, heat and stir to dissolve, forming a uniform solution.

Coating substrate: Apply the prepared solution evenly onto the back coating of the substrate.

Curing and drying: Perform high-temperature baking again to cure the polyester resin and form a release coating. The release coating mainly plays a role in preventing the ink layer from sticking to the substrate, ensuring that the ink can be smoothly transferred to the printing medium during the printing process.

4、 Produce ink coating

Ink configuration: Resin, wax, and pigment are added to a solvent in a certain proportion, heated and stirred to dissolve, forming a uniform ink solution. Resin and wax play a role in bonding and transferring ink, while pigments provide the desired color.

Coating substrate: Apply the prepared ink solution evenly onto the release coating of the substrate.

Curing and drying: Finally, baking is carried out at high temperature to solidify the ink and form an ink coating. The ink coating is the core part of the carbon ribbon, which directly determines the quality and effect of printing.

5、 Winding and cutting

After completing the coating production, roll the carbon ribbon onto a drum and cut it into different width specifications according to the needs of different models of printers.

6、 Quality control

Throughout the entire production process, it is necessary to strictly control the quality, ratio, coating thickness, curing temperature, and other parameters of the raw materials to ensure the stability of the performance and quality of the carbon ribbon. At the same time, various performance tests such as wear resistance, solvent resistance, printing effect, etc. need to be conducted to meet customer needs.

By following the above steps, an enhanced wax based carbon ribbon coating with excellent performance can be produced. This coating not only has excellent printing quality and effect, but also has good wear resistance, anti-static performance, and stability, which can meet various printing needs.
