What are the production processes of wax-based carbon strips?

The production process of wax-based carbon strip is a complex chemical and physical process, which mainly includes the following key steps:

1. Base film selection

Base film material: Polyester (PET) film is usually selected as the base film because it has excellent mechanical strength and thermal stability. The choice of base film is crucial to the performance of the final carbon band.

2. Toner preparation

Toner composition: Toner is composed of pigment, resin, wax and various additives. Pigments are responsible for providing color, while resins and waxes ensure that toner transfers properly and adheres to the medium when heated. Additives are used to improve various physical and chemical properties of toner, such as wear resistance and solvent resistance.

Mixing process: wax substances and resins are fully mixed and uniform under the condition of heating and melting, and then fully mixed and uniform with coloring agent and auxiliary agent to make ink. Temperature and time need to be controlled in this process to ensure that the components are fully mixed.

3. Coating process

Coating environment: The coating process needs to be carried out in a controlled environment to ensure uniform toner layers. This usually involves strict control of workshop temperature, humidity, and air cleanliness.

Coating amount control: The prepared ink is coated on the surface of the baseband, and the coating amount needs to be precisely controlled to ensure the consistency of the printing effect. Too much coating may lead to uneven carbon strip thickness, while too little coating may affect the printing effect.

4. Drying and curing

Drying process: The coated carbon strip undergoes a series of drying processes to remove solvents and solidify the toner. In this process, the temperature and time need to be controlled to avoid cracking or deformation of the toner layer.

5. Winding and cutting

Winding: The dried and cured carbon tape is wound onto a drum for easy storage and transportation.

Cutting: According to customer needs, the carbon strip is cut into different width specifications to meet the needs of different types of printers.

6. Quality inspection

Appearance inspection: Check the appearance of the carbon strip for defects, such as wrinkles, bubbles, scratches, etc.

Performance test: evaluate the printing effect, water resistance, wear resistance and other performance indicators of the carbon strip by printing test proofs.

7. Packaging and storage

Packaging: The qualified carbon belts are packaged in a certain amount for easy sale and use.

Storage: It is necessary to pay attention to the control of temperature and humidity during storage to ensure that the carbon strip can maintain good performance after long-term storage.

In summary, the production process of wax-based carbon strip is a multi-step, refined process, which requires strict control of the parameters and quality standards of each link to ensure the performance and quality of the final product. At the same time, with the continuous progress of technology and the constant change of market demand, the production process of wax-based carbon strip is also constantly innovative and optimized.
