How to reduce the delamination phenomenon in the production process of self-adhesive coated paper?

To reduce the delamination phenomenon in the production process of self-adhesive coated paper, you can start from the following aspects:

1. Raw material selection and quality control

Selection of high-quality raw materials: ensure that the selected coated paper and adhesive have a high quality, the quality of raw materials directly affect the performance of the final product.

Control the humidity of raw materials: Raw materials should maintain appropriate humidity during storage and use to avoid delamination caused by excessive humidity.

2. Production process optimization

Reasonable control of production speed: In the high-speed production process, it is necessary to reasonably control the production speed to avoid too fast leading to insufficient processing, resulting in stratification.

Adjust the coating process: Optimize the coating process to ensure that the adhesive is evenly coated on the coated paper, improve the bonding strength and reduce the risk of delamination.

Control drying temperature and time: In the drying process, the drying temperature and time should be strictly controlled to avoid excessive temperature or too long time leading to paper deformation or adhesive failure, resulting in delamination.

3. Equipment maintenance and adjustment

Periodically check the equipment: Check and maintain the production equipment regularly to ensure that the equipment is in good condition and avoid problems caused by equipment faults in the production process.

Adjust equipment parameters: Adjust equipment parameters according to the actual production situation, such as the amount of glue, pressure, etc., to meet the production needs of different specifications and quality of self-adhesive coated paper.

4. Environmental control

Keep the production environment stable: ensure that the temperature, humidity and other environmental parameters of the production workshop remain stable to avoid adverse effects on the production process and product quality due to environmental changes.

Reduce dust and impurities: Maintain the cleanliness of the production environment, reduce the impact of dust and impurities on the self-adhesive coated paper, and avoid the mixing of impurities leading to delamination.

5. Quality testing and monitoring

Strengthen quality inspection: Strengthen quality inspection in the production process, discover and deal with quality problems in time, and prevent unqualified products from flowing into the next process.

Establish a quality traceability system: Establish a sound quality traceability system to track and record raw materials, production processes and finished products throughout the process, so as to find the root cause of problems and take measures to improve them.

6. Staff training and operation specifications

Strengthen staff training: regularly train production employees to improve their understanding and ability of the production process and quality control of self-adhesive coated paper.

Develop operating specifications: Develop detailed operating specifications and strictly implement them to avoid problems in the production process due to improper operation.

To sum up, reducing the delamination phenomenon in the production process of self-adhesive coated paper needs to start from many aspects such as raw material selection, production process optimization, equipment maintenance and adjustment, environmental control, quality testing and monitoring, and staff training and operating norms. Through comprehensive policies and continuous improvement, the probability of stratification can be effectively reduced, and product quality and production efficiency can be improved.
