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

The production process of enhanced wax based carbon ribbon usually includes the following key steps:

1. Substrate preparation

Substrate selection: Polyester (PET) film is usually chosen as the substrate because it has excellent mechanical strength and thermal stability, making it suitable as a support material for carbon ribbons.

Substrate treatment: Clean and pre treat the substrate to ensure that the coating can firmly adhere to the substrate.

2. Preparation and coating of back coating

Preparation of back coating: Add organic silicon resin and other raw materials into a solvent, heat and stir to dissolve, and form a back coating solution.

Back coating coating: Immerse the substrate in the back coating solution, then take it out and bake it at high temperature to cure and dry the organic silicon, forming the substrate back coating. The main function of the back coating is to enhance the adhesion between the substrate and the ink coating, and prevent wear of the print head.

3. Preparation and coating of release coating

Preparation of release coating: Polyester resin and other raw materials are added to a solvent, heated and stirred to dissolve, forming a release coating solution.

Release coating coating: Apply the release coating solution onto the back coating of the substrate and heat dry to form a release coating. The main function of the release coating is to prevent the ink coating from sticking to the print head during the printing process.

4. Preparation and coating of ink coating

Ink coating preparation: Resin, wax, pigment and other raw materials are added to a solvent, heated and stirred to dissolve, forming an ink coating solution. The ratio and selection of these raw materials are crucial for the printing effect of carbon ribbon.

Ink coating coating: Apply the ink coating solution onto the release coating of the substrate and heat dry it to form an ink coating. The ink coating is the core part of the carbon ribbon, which directly determines the printing quality and effect.

5. Drying and curing

Drying process: During and after coating, the carbon ribbon needs to be dried to remove solvents and solidify the coating.

Curing treatment: For certain special carbon ribbons, additional curing treatment may be required to ensure the performance and stability of the coating.

6. Cutting and winding

Cutting: Cut the dried and cured carbon ribbon into predetermined widths to meet the needs of different types of printers.

Winding: Wrap the cut carbon ribbon onto a drum for storage, transportation, and use.

7. Quality inspection and packaging

Quality inspection: Conduct quality inspection on the produced carbon ribbon, including appearance inspection, adhesion testing, printing effect testing, etc., to ensure that the product quality meets the standards.

Packaging: Pack qualified carbon ribbons and label them with product information, production date, shelf life, and other details for easy sales and use.

In summary, the production process of enhanced wax based carbon ribbon is a complex process involving multiple steps, requiring strict control of process parameters and quality standards at each stage to ensure the production of high-quality carbon ribbon products.
