What are the solutions to the technical challenges of mixed base carbon belts?

For the technical challenges of mixed base carbon belts, solutions can be proposed from the following aspects:

First, improve the formulation design ability

Core challenge: The coating formula of thermal transfer carbon tape is the core trade secret of enterprises in the industry, and the core guarantee of technical performance and application effect of thermal transfer carbon tape. The general process of formula design is for enterprises to establish research and development projects through market research or user feedback information, conduct targeted screening among thousands of basic raw materials according to product development objectives, design the ratio of raw materials and functional structure collocation between coatings and form a preliminary scheme, adjust and optimize the formula after a pilot test, and then conduct pilot test. Finally achieve mass production. The development of large foreign enterprises started earlier, deep technical reserves, so the formula design ability is stronger, the product line is more complete, resin based bar code carbon strip, mixed based bar code carbon strip and medical thermal transfer film and other products are rich in variety and excellent performance. Domestic enterprises are mostly limited by the scale of capital, technical background and R & D personnel and other bottlenecks, with a strong resin base and mixed base product formulation design capabilities of the enterprise number is very small.

Solution: Domestic enterprises need to increase research and development investment, introduce and train formula design talents, strengthen cooperation with universities and research institutions, and improve their ability in mixed carbon strip formula design. At the same time, we can learn from the experience and technology of international advanced enterprises, and improve the scientific and effective formula design through technology introduction, digestion, absorption and innovation.

Second, optimize the coating preparation process

Core Challenge: The high volume, continuous and stable preparation of high-quality coatings is one of the key links in the production of thermal transfer carbon strips. Coating preparation usually includes feeding, dissolution, dispersion, grinding, testing, transportation and other processes. The technical difficulties of coating preparation are mainly reflected in the selection, structural design and function optimization of chemical kettle, dispersion kettle and grinding equipment, so as to match the coating characteristics of different products and different coatings, and meet the diversified requirements of technical indicators such as paint particle size, viscosity and solid content of product production. In addition, technical means such as automatic control are needed to improve the coating preparation efficiency and quality stability and consistency, laying the foundation for the efficiency and process accuracy of subsequent coating links.

Solution: Enterprises should introduce advanced coating preparation equipment and technology, optimize and upgrade chemical kettle, dispersion kettle and grinding equipment, etc., to improve the accuracy and stability of equipment. At the same time, the application of automatic control technology is strengthened to realize real-time monitoring and adjustment of the coating preparation process to ensure the stability and consistency of the coating quality.

Third, improve the coating technology

Core challenge: The coating process technology directly affects the printing effect and quality of the carbon strip. Enterprises in the industry need to combine their own product characteristics, focusing on the research, selection and combined application of coating methods, feeding methods and scraper types, the matching of oven heating methods, oven length, intake and exhaust air volume with product characteristics and production efficiency, the relationship between temperature and humidity in the process environment and product quality, and the research and combined application of various electrostatic elimination methods. The relationship between oven inlet and exhaust air volume and energy consumption, the matching between tension parameter setting and different product characteristics, the study of coating quality monitoring and coating defect elimination measures, the research and application of automatic control technology means, etc., to carry out long-term technology research and development and application exploration.

Solution: Enterprises should strengthen the research and development and innovation of coating technology, introduce advanced coating equipment and technology, and improve the coating speed and process stability. At the same time, according to the production requirements of different products, the process path and coating device are designed and optimized to ensure the high quality and high stability of the carbon strip printing effect.

Fourth, improve product performance and application range

Core challenge: With the continuous upgrading of downstream application scenarios, users' performance requirements for mid-to-high-end products such as thermal transfer carbon strips, especially resin-based barcode carbon strips, mixed-based barcode carbon strips and medical thermal transfer films continue to increase. First of all, users often hope that the same carbon belt is suitable for multiple types of printers and a variety of printed media, so as to reduce the procurement and time costs caused by frequent replacement of carbon belts, and high compatibility has become one of the development directions. Secondly, the application of high-end products continues to expand to unconventional and even extreme environments, requiring products to meet the extreme environment for wear resistance, weather resistance, corrosion resistance, washing resistance and other performance requirements, such as high temperature resistance ceramic carbon belt; Finally, in order to improve printing efficiency and reduce production costs, users need thermal transfer carbon tape with faster printing speed, and from offline printing to online printing development, to meet the development trend of production integration and automation.

Solutions: Enterprises should strengthen the research and development and innovation of mixed base carbon strip product performance, improve product compatibility, wear resistance, weather resistance, corrosion resistance, washing resistance and other properties. At the same time, for different application scenarios and needs, the development of mixed base carbon strip products with specific performance to meet the diversified needs of the market. In addition, strengthen cooperation with printer manufacturers to promote the compatibility and matching of mixed base carbon strips with printers, and improve the overall printing effect and use experience.

To sum up, in view of the technical challenges of the mixed base carbon belt, the technical level and market competitiveness of the mixed base carbon belt can be improved through technological innovation and upgrading from the aspects of improving the formulation design ability, optimizing the coating preparation process, improving the coating technology and improving the product performance and application range.
