Enhancing the coating uniformity of the all-resin carbon strip is a key factor to ensure the print quality and properties of the carbon strip. In order to ensure coating uniformity, it can be controlled and optimized from the following aspects:


1. Equipment selection and adjustment

High-precision coating equipment: Select a coating equipment with high precision to ensure that the equipment can maintain a stable coating width and speed during operation.

Equipment adjustment and maintenance: Regular maintenance and adjustment of the coating equipment, such as checking the flatness of the roller, friction, etc., to ensure that the equipment is in the best working condition.

2. Process control

Coating speed: According to the type of carbon strip and the performance of the printer, choose the appropriate coating speed. Too fast a coating speed may result in uneven ink layer distribution, while too slow a coating speed may reduce production efficiency.

Coating thickness: Precisely control coating thickness to ensure uniform ink layer. This can be achieved by adjusting the measuring system of the coater or the pressure of the scraper.

Temperature and humidity control: During the coating process, maintain a suitable temperature and humidity environment to reduce the influence of inconsistent drying speed on coating uniformity.

3. Material quality control

Carbon strip substrate: Choose a carbon strip substrate with a flat surface and uniform thickness to reduce the influence of the substrate itself on the coating uniformity.

Resin ink: The use of resin ink with stable viscosity and good fluidity ensures that it can be uniformly attached to the substrate during the coating process.

4. Selection and maintenance of coating roller

Coating roller material and hardness: Select wear-resistant, corrosion-resistant and moderate hardness coating roller material to reduce the impact of roller surface wear on coating uniformity.

Coating roll cleaning: regularly clean the surface of the coating roll, remove the attached impurities and ink stains, and maintain the flatness and cleanliness of the roll surface.

Coating roller dynamic balance: Ensure that the coating roller has good dynamic balance performance to reduce vibration and noise during operation and improve coating uniformity.

5. Quality control and testing

On-line detection: On-line detection equipment is used to monitor the thickness and uniformity of the ink layer during the coating process in real time, so as to discover and solve the problem in time.

Finished product testing: Sample the coated carbon strip to check whether its coating uniformity, adhesion and other performance indicators meet the requirements.

6. Environmental considerations

Workshop environment: Keep the workshop environment clean and stable, reduce the influence of dust, vibration and other external factors on coating uniformity.

Protective measures: Take necessary protective measures in the coating process, such as the use of protective covers, vacuum cleaners, etc., to reduce the pollution of harmful substances to the operator and the environment.


To sum up, it is necessary to comprehensively consider and optimize the coating uniformity of all-resin carbon strip from the aspects of equipment selection, process control, material quality control, selection and maintenance of coating rolls, quality control and detection. By implementing these measures, the coating uniformity of the carbon strip can be significantly improved, thus ensuring the stable and reliable printing quality and performance of the carbon strip.
