What is the production process of all resin carbon ribbon?

The production process of all resin carbon ribbon is a precision chemical technology process involving multiple steps. The following is a typical production process of all resin carbon ribbon:

1、 Raw material preparation

Base film selection: Polyester (PET) film is usually chosen as the base film because it has excellent mechanical strength and thermal stability. The selection of base film is crucial for the performance of the final carbon ribbon.

Resin and additive preparation: Prepare resins (such as polyurethane modified silicone resin, acrylic modified silicone resin, etc.), waxes (such as PE wax, Brazilian palm wax, etc.), pigments (such as inorganic pigments), dispersants, anti-static agents, leveling agents, and other additives according to the formula.

2、 Base film treatment

Corona treatment: Apply corona on one or both sides of the base film to improve the wettability and adhesion of the base film surface, facilitating subsequent coating application.

3、 Coating application and drying

Back coating coating: The prepared back coating is applied to one side of the base film, usually using a gravure coating machine, and the coating speed and drying temperature (such as 60 ℃) are controlled to evaporate the solvent and form the back coating. The main function of the back coating is to enhance the adhesion and friction between the carbon ribbon and the print head, and improve the printing effect.

Release layer coating: Apply release layer coating on the other side of the base film using a gravure coating machine, and control the coating speed and drying temperature (such as 60 ℃) to form a release layer. The main function of the release layer is to prevent toner from adhering to the print head during the printing process, ensuring smooth printing.

Ink layer coating: Apply ink layer coating on the release layer, which is composed of resin, pigment, wax, dispersant, etc. Similarly, a gravure coating machine is used for coating, and the coating speed and drying temperature (such as 80-140 ℃) are controlled to form an ink layer. The ink layer is the core part of the carbon ribbon, responsible for transferring images or text onto the medium during the printing process.

4、 Post processing and finished product preparation

Drying and curing: After all coatings are applied, the carbon ribbon needs to be dried and cured to remove residual solvents, ensure a tight bond between the coatings, and improve the overall performance of the carbon ribbon.

Cutting and winding: Cut the dried and solidified carbon ribbon into different width specifications to meet the needs of different models of printers. Then, the cut carbon ribbon is wound onto a roll to form the finished product.

5、 Quality control and testing

Strict quality control and testing are required for raw materials, semi-finished products, and finished products throughout the entire production process. This includes testing the thickness and uniformity of the base film, the thickness, adhesion, wear resistance, and other performance indicators of the coating to ensure the quality and stability of the final product.

It should be noted that different all resin carbon ribbon products may have different production processes and formulas. The above description is a typical production process of all resin carbon ribbon, and the specific process may vary depending on product characteristics and production requirements.
