PE electrostatic film use problem solving

- Sep 15, 2018 -

PE electrostatic film can be used for surface protection of optical glass, plastic sheet, sheet, plastic lens, aluminum-plastic board, sun board, etc., so that the product can be protected from pollution and scratch during transportation, processing, stamping, forming and storage. Product surface, improve yield and reduce finished product. PE electrostatic film is produced by high-end imported equipment in the 1000-level clean room. The film has high flatness, excellent cleanliness, flexibility and excellent automatic exhaust performance.

 

The same applies to surface protection of products with high cleanliness such as precision electronics and high-end sheets. The PE electrostatic film is easy to stick, and the adhesion force changes little after the attachment. The product quality is excellent in cleanliness, not easy to break, not easy to fall off, not easy to deform, and has a good protection effect on the surface of the object. However, in practical applications, there are still some problems with the use of this protective film. Let's understand the specific situation and the appropriate solution.

 

First, during use, it was found that the adhesion between the PE electrostatic film and the protected article was not strong enough, and it fell off during transportation and use. The reason why this happens is mainly because the pressure sensitive adhesive used in the production of the protective film product is not sufficiently viscous, and there is also a possibility that the pressure of the molding machine used by the user when carrying out the mold is insufficient, or The surface of the profile is not clean, dust or paint, etc., resulting in a decrease in the adhesion of the sensitive adhesive.

 

For such problems, we need to pay attention to maintaining the cleanliness of the surface of the article before using the PE electrostatic film, and to properly increase the film pressure to prevent the problem of falling off. Secondly, it may also be the case that the protective film is lifted at both ends after a period of use. The main reason for this phenomenon is that the protective film is stretched to a greater extent during the pasting process with the protected profile. After the post is applied, in the high temperature environment, unnecessary retraction occurs.

 

Therefore, in the process of producing PE electrostatic film, it is necessary to take into account the influence of ambient temperature on the use of the product, and avoid unnecessary surface stretching during the pasting process. Third, we may also encounter difficulties in stripping protective film products. On the one hand, the sensitive adhesive used for the protective film product is not a special sensitive adhesive for the protective film, on the other hand, the material used for the protective film master tape is too soft to withstand the pulling force at the time of peeling, and breakage occurs at the time of peeling.

 

In addition, some users have found that PE electrostatic film remains after peeling. Although these products can be effectively peeled off, there is a protective film on the surface of the profile. This is because the protective film is combined with the protected profile and has a suitable environment such as sunlight and moisture. Cooperation.http://www.pe-protectionfilm.com/
