What is the production process of the mixed base carbon strip?

The production process of the mixed base carbon strip is a complex process involving many steps, including the preparation of the base film, toner coating, drying and curing, and cutting and splitting. The following is a detailed overview of the mixed base carbon strip production process:

1. Base membrane preparation

Material selection: The base film is the basis of the mixed base carbon strip, and polyester (PET) film is usually selected as the base material because of its excellent mechanical strength and thermal stability.

Pretreatment: The base film may require pretreatment before coating, such as cleaning, corona treatment, etc., to enhance the adhesion of the toner.

2. Toner coating

Toner composition: The toner of the mixed base carbon strip is composed of resin, wax, pigment and various additives, where the ratio of resin and wax is adjusted according to the specific application needs to achieve the desired printing effect and durability.

Coating process: In a controlled environment, the toner is evenly coated on the base film. This step requires precise control of coating volume, uniformity and speed to ensure the quality of the toner layer.

3. Drying and curing

Solvent removal: The coated carbon strip needs to undergo a drying process to remove the solvent from the toner. This step helps to solidify the toner, improve the stability of the carbon strip and the printing effect.

Curing treatment: In some processes, further curing of the carbon strip after drying may also be required to enhance the adhesion and durability of the toner.

4. Cut the subvolume

Cutting: According to the needs of different printers, the long strip of carbon tape is cut into different widths.

Subwinding: The cut carbon tape is wound onto the drum to form the final product.

5. Quality control and testing

Quality control: In the entire production process, the raw materials and finished products need to carry out strict quality control, including appearance inspection, size measurement, performance testing, etc., to ensure that the quality of the carbon strip meets the standard.

Performance test: The carbon strip is tested for wear resistance, solvent resistance, scratch resistance, printing effect and other performance to ensure that it meets the application requirements.

6. Packaging and marking

Packaging: The qualified carbon strip product is packaged to protect it from damage.

Identification: Clearly identify product specifications, models, production dates, batch numbers and other information on the package for easy traceability and management.

In summary, the production process of the mixed base carbon strip is a multi-step, high-precision process that requires strict control of each link to ensure the quality and performance of the final product. With the continuous advancement and innovation of technology, the production process of mixed base carbon belts is also constantly optimized and improved to meet the changing needs of the market.
