How is mixed carbon ribbon made?

The production process of mixed carbon ribbon integrates precision chemical technology, and the specific steps are as follows:

1. Preparation of basement membrane:

Choose high-quality base film, usually polyester (PET) film, due to its excellent mechanical strength and thermal stability.

2. Ink powder coating:

Apply toner on the base film, which is usually composed of pigments, resins, waxes, and various additives.

Pigments are responsible for providing color, while resins and waxes ensure that toner can be properly transferred and attached to the medium when heated.

Additives are used to improve various physical and chemical properties of toner, such as wear resistance, solvent resistance, etc.

The coating process needs to be carried out in a controlled environment to ensure that the toner layer is uniform and consistent.

3. Drying and curing:

The coated carbon ribbon needs to undergo a series of drying processes to remove solvents and solidify the toner.

4. Winding and cutting:

The carbon ribbon will be wound onto a roll and cut into different width specifications to meet the needs of different models of printers.

5. (Optional) Multi layer structure:

Some mixed carbon ribbons may contain multiple layers of structure, such as release layer, heat transfer ink layer, heat-resistant layer, and back coating, to further improve their performance.

These layers are usually made of specific materials, such as brazilian wax, aqueous acrylic lotion, ethanolamine, deionized water, ethanol, dispersant, polyester resin, nano silver particles, organic dyes, additives, silicone resin, polyethylene butyral resin, curing agent, catalyst, butyl acetate, butanone, etc.

6. Quality control and testing:

Strict quality control is required for raw materials and finished products throughout the entire production process to ensure that the quality of carbon ribbon meets standards.

A series of tests and inspections are still needed, including testing the wear resistance, printing effect, high temperature resistance, and other properties of the carbon ribbon.
