What are the key technologies for enhancing the production process of wax based carbon ribbon?

The key technologies for enhancing the production process of wax based carbon ribbon mainly include the following aspects:

1、 Substrate selection and processing

Substrate selection: High quality polyester (PET) film is usually used as the substrate for enhanced wax based carbon ribbon, as it has excellent mechanical strength and thermal stability, ensuring the durability and printing effect of the carbon ribbon.

Substrate treatment: During the production process, the substrate needs to undergo pre-treatment steps such as cleaning and drying to remove surface stains and moisture, improve coating adhesion and uniformity.

2、 Coating preparation and coating technology

Coating preparation:

Back coating: Dissolve organic silicon resin and other raw materials in a solvent, then apply it to the back of the substrate, and after curing and drying, form a back coating to improve the tear resistance and wear resistance of the carbon ribbon.

Release coating: Dissolve polyester resin and other raw materials in a solvent, apply it to the front of the substrate, and form a thin release coating to facilitate the smooth separation of carbon ribbon and printing medium during the printing process.

Ink coating: Mix resin, wax, pigment and other raw materials in a certain proportion and dissolve them in a solvent, then apply them on the release coating, and form an ink coating after curing and drying. This is the key layer that determines the printing effect of carbon ribbon.

Coating technology: The coating process needs to be carried out in a controlled environment to ensure the uniformity and thickness consistency of the coating. The commonly used coating methods include scraper coating, comma scraper coating, gravure coating, etc.

3、 Curing and drying technology

Curing: After applying each layer of coating, curing treatment is required to cause chemical reactions or physical changes in the resin, wax, and other components in the coating, forming a stable coating structure. The curing temperature and time need to be adjusted according to the composition and thickness of the coating.

Drying: After curing, it is necessary to perform drying treatment to remove solvents and moisture from the coating, improve the dryness and adhesion of the coating. The drying temperature and time also need to be adjusted according to the composition and thickness of the coating.

4、 Quality control and testing

Online testing: During the production process, it is necessary to conduct online testing on the thickness, uniformity, adhesion, etc. of each layer of coating to ensure that the product quality meets the standards.

Finished product testing: Conduct finished product testing on the enhanced wax based carbon ribbon produced, including printing effect, scratch resistance, weather resistance, and other indicators, to ensure stable and reliable product quality.

5、 Environmental protection and safety production

Environmentally friendly materials: Select environmentally friendly materials to reduce harmful substance emissions during the production process and meet environmental protection requirements.

Safety production: Strengthen safety production management to ensure equipment safety, personnel safety, and environmental protection during the production process.

In summary, the key technologies involved in enhancing the production process of wax based carbon ribbon include substrate selection and treatment, coating preparation and coating technology, curing and drying technology, quality control and testing, as well as environmental protection and safety production. The mastery and application of these key technologies are of great significance for improving the product quality and market competitiveness of wax based carbon ribbons.
