What are the steps involved in the production process of wax based carbon ribbon?

The production process of wax based carbon ribbon mainly includes the following steps:

1、 Prepare the basement membrane

Material selection: High quality polyester (PET) film is usually chosen as the base film because it has excellent mechanical strength and thermal stability, making it an ideal material for making carbon ribbons.

Pre treatment: Necessary pre-treatment of the base film, such as cleaning, electrostatic removal, etc., to ensure the smooth progress of the subsequent coating process.

2、 Apply toner

Toner preparation: Toner is usually composed of pigments, resins, waxes, and various additives. Pigments are responsible for providing color, resins and waxes are used to ensure that toner can be properly transferred and attached to the medium when heated, while additives are used to improve various physical and chemical properties of toner, such as wear resistance, solvent resistance, etc.

Coating process: In a well controlled environment, evenly apply the prepared toner onto the base film. This step requires precise control of coating thickness and uniformity to ensure the printing effect of the final product.

3、 Drying and solidification

Drying process: The coated carbon ribbon needs to undergo a series of drying processes to remove solvents and solidify the toner. This step is usually carried out under specific temperature and time conditions to ensure that the toner is completely dry and fixed on the base film.

Curing treatment: In some cases, additional curing treatment is required for the carbon ribbon to improve the adhesion and durability of the toner.

4、 Apply back coating and release layer (if necessary)

Back coating: In order to enhance the adhesion and wear resistance of carbon ribbon, it is sometimes necessary to apply a layer of back coating on the back of the base film. The back coating is usually composed of materials such as silicone resin, which has excellent adhesion and wear resistance.

Release layer: In some wax based carbon ribbon production processes, it is also necessary to apply a release layer on top of the toner layer. The release layer is usually composed of materials such as polyester resin, which has excellent release performance and wear resistance, helping to protect the toner layer and prevent adhesion during the printing process.

5、 Winding and cutting

Winding: Roll the dried and cured carbon ribbon onto a drum for subsequent use and storage.

Cutting: Cut the carbon ribbon into different width specifications according to customer needs to meet the needs of different models of printers.

6、 Quality inspection and packaging

Quality inspection: Conduct quality inspection on the wax based carbon ribbon produced, including adhesion testing, wear resistance testing, clarity testing, etc., to ensure that the product quality meets customer requirements.

Packaging: Pack the wax based carbon ribbon that has passed inspection for transportation and sale. The packaging material should have good moisture-proof, dust-proof, and anti-static properties to protect the carbon ribbon from damage during transportation and storage.

The above are the main steps of the wax based carbon ribbon production process. The precise control and optimization of these steps are crucial for improving product quality and production efficiency.
