E-paper warping in the production process is a relatively common phenomenon, the reasons for the warping of the edge of the electronic paper may be manifold, but can be attributed mainly to the following points:

1, poor quality of edge sealant or insufficient bonding effect. If the use of poor quality sealant or bonding effect is insufficient, may lead to the edge of the electronic paper can not be sufficiently fixed, resulting in the phenomenon of warping. At this time, you need to replace the high-quality sealant, and to ensure that the formula and dosage of the glue is correct.

2, the electronic paper itself has quality problems. If the electronic paper itself has quality problems, such as uneven thickness, surface roughness, etc., may also lead to edge warping. At this point, you need to replace the qualified electronic paper.

3, the influence of environmental factors. Environmental factors will also have an impact on the sealing effect of electronic paper. For example, changes in temperature and humidity may lead to thermal expansion and contraction of electronic paper, resulting in the phenomenon of edge warping. At this point, the need to control the temperature and humidity when sealing the edge, in order to avoid thermal expansion and contraction caused by temperature changes.

In order to solve the problem of warped edges of electronic paper, the following measures can be taken:

1、Replace the high-quality edge sealing glue to ensure the performance of the glue and bonding effect.

2、Ensure the quality and uniform thickness of electronic paper, and choose the electronic paper that meets the requirements.

3、Control the temperature and humidity when sealing the edge, in order to avoid thermal expansion and contraction caused by temperature changes.

4、Strengthen quality management, establish a perfect quality management system, strict inspection and control of all aspects of the production process, timely detection and resolution of problems, improve product quality.

Therefore, to solve the problem of warped edges of electronic paper need to start from a number of aspects, including the selection of high-quality sealing adhesive, to ensure that the quality and thickness of the electronic paper is uniform, control the temperature and humidity when sealing the edges as well as to strengthen the quality management and other measures. Through the implementation of these measures, the quality and stability of electronic paper edge sealing can be effectively improved, and the service life of electronic paper can be extended.
