What are the key control points in the production process of mixed carbon ribbon?

The key control points in the production process of mixed carbon ribbon mainly include the following aspects:

1、 Selection and treatment of basement membrane

Base film material: Polyester (PET) film is usually selected as the base film due to its excellent mechanical strength and thermal stability.

Thickness and flatness of the base film: The thickness and flatness of the base film have a significant impact on the printing effect and durability of the carbon ribbon, and need to be strictly controlled.

2、 Ink formula and coating

Ink formula: Ink is composed of pigments, resins, waxes, and various additives, and needs to be precisely formulated according to printing requirements and carbon ribbon performance requirements.

Coating process:

Coating amount: It is necessary to ensure that the ink layer is uniform and consistent. Excessive or insufficient coating can affect the printing effect.

Coating environment: The coating process should be carried out in a controlled environment to avoid the influence of external factors such as dust and humidity on the ink layer.

3、 Drying and solidification

Drying temperature and time: The appropriate drying temperature and time should be determined based on the ink formula and base film material to ensure that the solvent evaporates fully and the toner solidifies.

Drying uniformity: It is necessary to ensure that the drying process is uniform and avoid problems caused by insufficient or excessive local drying.

4、 Cutting and winding

Cutting accuracy: It is necessary to accurately cut the carbon ribbon according to the printer model and technical specifications, ensuring that the width, length, and tightness meet the requirements.

Winding quality: During the winding process, it is necessary to avoid problems such as wrinkling, breakage, or uneven elasticity of the carbon tape, to ensure that the carbon tape can be used smoothly in the printer.

5、 Quality control and testing

Raw material inspection: Strictly inspect raw materials such as base film and ink to ensure compliance with production requirements.

Production process monitoring: Real time monitoring of coating, drying, cutting and other production processes to ensure that the parameters of each process meet the requirements.

Finished product testing: Conduct wear resistance, printing effect, high temperature resistance and other performance tests on the produced carbon ribbon to ensure that the product quality meets the standards.

6、 Environment and health

Production environment: It is necessary to maintain cleanliness and suitable temperature and humidity conditions in the production workshop to avoid the impact of dust and pollutants on carbon ribbon production.

Personnel hygiene: Production personnel must comply with hygiene standards and avoid bringing pollutants into the production area.

7、 Safety and environmental protection

Safety production: It is necessary to strictly comply with safety production regulations to ensure the safety of equipment and personnel during the production process.

Environmental protection requirements: It is necessary to comply with environmental regulations, dispose of waste in the production process reasonably, and reduce the impact on the environment.

In summary, the key control points in the production process of hybrid carbon ribbon involve multiple aspects, from raw material selection to finished product testing, every link needs to be strictly controlled to ensure that the quality and performance of the carbon ribbon meet the requirements.
