What are the steps of the production process of the mixed base carbon strip?

The production process of the mixed base carbon strip involves several key steps, and the following production process is organized according to information from highly authoritative sources:

First, the preparation stage

1. Material selection and preparation:

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

Prepare the ink materials, including pigments, resins, waxes, and various additives that will work together to form the print layer of the carbon strip.

Second, coating stage

1. Release coating:

One side of the base film is coated with a release layer, which is usually composed of a mixture of silicone resin, polyester resin, wax emulsion and water-based release agent to ensure that the ink layer can be smoothly transferred to the substrate during the printing process.

2. Ink coating:

An ink layer is coated on top of the release layer, and the ink layer is composed of raw materials such as resin, additives, pigments, and functional emulsions to provide the color and image information required for printing.

3. Adhesive coating:

A bonding layer is coated on top of the ink layer, which may contain components such as sulfur powder and phosphorus powder to enhance the bonding between the ink and the substrate.

4. Protective coating:

The adhesive layer is coated with a protective layer, usually a grease material, to protect the adhesive layer from the damage of the external environment.

Third, drying and curing

1. Drying process:

The coated carbon strip undergoes a series of drying processes to remove the solvent and solidify the toner layer. The drying temperature and time need to be strictly controlled to ensure the stability of the ink layer and the printing effect.

Fourth, back processing

1. Lubrication coating:

A lubricating layer, usually composed of materials such as talc and silicone, is coated on the back of the base film to reduce friction between the print head and the carbon strip and extend the service life of the print head.

Fifth, cutting and packaging

1. Slitting and rewinding:

A slitting and winder is used to cut continuous carbon strips into different widths to meet the needs of different printer models. At the same time, the cutting tension and the tightness of the carbon tape are adjusted to ensure that the performance of the carbon tape roll can be normally played in the thermal transfer printer.

2. Packaging and marking:

The finished carbon belt is packaged, and the product information, including model, specification, production date, etc. is clearly marked on the package to ensure the traceability of the product.

Sixth, quality control and testing

1. Quality control:

In the entire production process, the raw materials and finished products are strictly controlled, including appearance inspection, size measurement, performance testing, etc., to ensure that the quality of the carbon strip meets the standard.

2. Performance test:

The wear resistance, printing effect, high temperature resistance and other properties of the carbon belt are tested to ensure that the carbon belt can meet the needs of different users.

In summary, the production process of the mixed base carbon strip includes several steps, such as preparation stage, coating stage, drying and curing, back treatment, slitting and packaging, quality control and testing. These steps together ensure the quality of the carbon strip and the printing effect.
