What are the production processes of mixed carbon ribbon?

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

1. Basement membrane preparation

Choosing a base film: Polyester (PET) film is usually chosen as the base film for mixed carbon ribbon due to its excellent mechanical strength and thermal stability.

Base film treatment: The base film may need to be pre treated, such as corona treatment, to improve its adhesion with toner.

2. Ink preparation

Raw material mixing: The ink of mixed carbon ribbon is made by mixing wax, resin, carbon powder, additives and other components in a certain proportion. The selection and proportion of these components have a significant impact on the printing effect and durability of carbon ribbons.

Grinding and dispersion: Grind and disperse the mixed ink raw materials to ensure that the ink particles are uniform and delicate, avoiding problems such as clogging or unclear printing during the printing process.

3. Ink coating

Coating process: Use precision coating equipment to evenly apply ink onto the base film. The parameters such as coating amount, coating speed, and coating pressure need to be precisely controlled to ensure the thickness and uniformity of the ink layer.

Drying and curing: The coated base film needs to undergo drying and curing treatment to remove solvents and cure the ink layer. The drying temperature and time need to be adjusted according to the ink formula and coating amount.

4. Back treatment

Coating lubricant: Apply a layer of lubricant on the back of the base film to reduce friction between the print head and the base film, and extend the service life of the print head.

Drying: After applying lubricant, the base film needs to be dried again.

5. Cutting and winding

Slitting: Cut the dried base film into predetermined widths to meet the needs of different models of printers.

Winding: Wrap the cut carbon ribbon onto a drum to form the finished carbon ribbon.

6. Quality Inspection and Packaging

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

Packaging: Pack the carbon ribbon that has passed the inspection, label the product model, specifications, production date, and other information for storage and transportation.

7. Storage and transportation

Storage conditions: Mixed carbon ribbon should be stored in a dry, cool, ventilated place, away from direct sunlight and high temperature environment.

Transportation requirements: During transportation, the carbon ribbon should be protected from factors such as compression, collision, and moisture to ensure that the product maintains good quality when it reaches the customer's hands.

It should be noted that there may be certain differences in the production process of mixed carbon ribbons from different manufacturers and models. In addition, with the continuous advancement of technology and changes in market demand, the production process of mixed carbon ribbon is also constantly being optimized and improved.
