What is the production process of all resin carbon strip?

The production process of all-resin carbon strip is a complex process involving precision chemical technology, which can be mainly divided into the following key steps:

First, raw material preparation

Base film selection: The all-resin carbon strip usually uses high-quality polyester (PET) film as the base film, because PET film has excellent mechanical strength and thermal stability, which is essential for the performance of the final carbon strip.

Second, ink production and coating

1.Ink production: Ink is the core component of the all-resin carbon strip, which is usually composed of resins, pigments and various additives. The resin is the key ingredient that ensures the toner transfers correctly and adheres firmly to the medium when heated, while the pigment is responsible for providing the color. The additives are used to improve the physical and chemical properties of the ink such as wear resistance and solvent resistance.

2.Coating process: In a controlled environment, the ink is evenly coated on the PET base film. The coating process needs to ensure that the ink layer is uniform, no white spots, no stripes, no white strips. At the same time, the other side of the base film is coated with lubricant to prevent wear of the print head and prevent static electricity.

Third, drying and curing

The coated carbon strip undergoes a series of drying processes to remove the solvent and cure the ink. This step is critical to the final quality and performance of the carbon strip.

Four, cutting and packaging

1.Slitting: The use of slitting and rewinding machine to cut large rolls of carbon tape into different widths to meet the needs of different types of printers. In the slitter process, it is necessary to accurately grasp the cutting tension and the tightness of the carbon strip to ensure the normal performance of the carbon strip in the printer.

2.Packaging: In order to ensure good printing results, thermal transfer carbon tape products must be able to provide adequate protection and clear identification of the product during packaging to ensure its traceability.

Fifth, quality control and testing

Throughout the production process, strict quality control of raw materials and finished products is required. This includes a series of tests and inspections, such as wear resistance testing, printing effect testing, high temperature resistance testing, etc., to ensure that the carbon strip can meet the needs of different users and industry standards.

Sixth, innovation and R&D

With the change of market demand and the development of technology, the production process of all-resin carbon belt is also constantly innovative and improved. For example, some companies are exploring the possibility of water-based coatings instead of solvent coatings to reduce the use and volatilization of organic solvents and achieve environmental protection in the production process. At the same time, for the needs of specific application scenarios, such as high temperature resistance, chemical corrosion resistance and other extreme environments, carbon belt products with special properties are also being developed.

In summary, the production process of all-resin carbon belt is a process involving multiple links and complex technologies. By precisely controlling the process parameters and quality standards at each step, it is possible to produce high-quality, high-performance all-resin carbon strip products.
