What are the main quality problems of mixed base carbon belts?

The quality problem of the mixed base carbon belt may involve many aspects, and the following are some common problems:

1. Paper core inner diameter error:

Description of the problem: the inner diameter tolerance of the carbon strip paper core is set too large or too small, resulting in a large inner diameter error, which affects the work of the printer, such as the carbon belt can not be installed into the printer or the printer's shaft can not afford the carbon belt.

Impact: The carbon belt may not be installed or used normally, affecting the printing efficiency.

2. Carbon band wrinkle:

Description of the problem: Carbon belt in the cutting or processing process, due to poor tension control, resulting in wrinkled carbon belt.

Impact: The wrinkled carbon belt may cause a small area to print without words when printing, affecting the print quality.

3. Carbon belt gaps:

Problem description: In the process of carbon strip production, due to improper processing of light film, there are blank areas in carbon belt.

Impact: The blank area will lead to incomplete printing information, affecting the printing effect.

4. Needle eye (bubble) :

Problem description: Needle holes or bubbles appear on the carbon belt, usually due to the ink is not evenly applied.

Impact: Pinholes or bubbles can lead to incomplete information printing when printing, affecting the print quality.

5. Carbon tape adhesion:

Description of the problem: During transportation or storage, the carbon tape sticks together because the ambient temperature is too high.

Impact: Adhesive carbon strips require additional handling before use, increasing the difficulty and cost of use.

6. Paper core running edge:

Problem description: The carbon strip paper core has no running edge, that is, the edge of the paper core is not neat.

Impact: It may lead to broken tape during the working process, and the edge of the carbon belt cannot be printed up.

7. Improper proportion of ingredients:

Problem description: The ratio of wax base and resin component in the mixed base carbon strip is improper, such as the wax base component is too high and the resin component is too low.

Impact: Can not highlight the huge advantages of the mixed base carbon strip, such as friction resistance, corrosion resistance.

8. Improper winding tightness:

Problem description: The carbon tape is wrapped too tightly or too relaxed during processing.

Impact: After the carbon belt is installed on the printer, it cannot be run perfectly with the printer, affecting the printing effect.

In order to ensure the quality of the mixed base carbon strip, manufacturers should strictly control all aspects of the production process, from raw material procurement, production process, quality detection to packaging and transportation. At the same time, the user should also pay attention to the storage and transportation conditions when using the mixed base carbon strip to avoid the impact of adverse factors such as high temperature and humidity on the quality of the carbon strip.
