What are the key process links in the production of TTO high-speed coding carbon tape?

In the process of producing TTO (thermal transfer coding) high-speed coding carbon tape, the key process links mainly include the following aspects:

1. Raw material selection and preparation

Ink layer materials: Choose high-quality mixed base, advanced mixed base or resin based inks, which need to have good adhesion, scratch resistance, chemical resistance and other characteristics.

PET film: PET film with high strength, high transparency, excellent chemical stability and thermal stability is selected as the carrier material.

Back coating material: Prepare a special coating material containing lubricants or other additives to reduce print head wear, prevent static electricity and enhance heat transfer.

2. Coating

The ink layer is evenly coated on the PET film to ensure that the thickness of the ink layer is uniform to obtain a good printing effect. This link requires precise control of the coating speed and coating amount to avoid print quality problems caused by too thick or too thin ink layers.

3. Back coating treatment

A special coating is applied to the back of the PET film to form a back coating. This coating needs to be uniform and smooth to ensure good contact with the print head and reduce wear.

4. Drying and curing

After coating the ink layer and the back coating, the carbon strip needs to be dried and cured. This process is usually carried out by heating, allowing the ink layer and back coating to quickly dry and cure on the PET film. The temperature and time of drying and curing need to be precisely controlled to ensure the quality and stability of the coating.

5. Cutting and packing

The carbon strip after drying and curing is segmented according to the specified width to obtain the TTO high-speed coding carbon strip product that meets the requirements.

The carbon belt after cutting is packaged to prevent dust, impurities, etc. from polluting the surface of the carbon belt, and to protect the quality of the carbon belt during transportation and storage.

6. Quality inspection

Quality inspection is carried out in all aspects of the production process, including raw material quality, coating thickness, drying and curing effect, cutting accuracy, etc., to ensure that the quality and performance of the final product meet the standard requirements.

7. Environmental protection

With the improvement of environmental protection requirements, it is also necessary to pay attention to environmental protection treatment in the process of producing TTO high-speed coding carbon belts. For example, the waste generated in the production process is classified and treated, and the hazardous waste is safely disposed of.

In summary, the key process links of the production of TTO high-speed coding carbon belt include raw material selection and preparation, coating, back coating treatment, drying and curing, cutting and packaging, quality testing and environmental protection treatment. These processes require precise control of various parameters and process conditions to ensure that the quality and performance of the final product meet market demands.
