In order to keep the aluminum composite panel intact before use, protection measures are usually adopted. The aluminum composite panel protection film is a material specially used for its surface protection. When using aluminum composite panel protective film, it is necessary to enhance its binding degree with the object surface, so as to promote its protective effect.
In practical application, often encounter the phenomenon of the aluminum composite panel protective film sticking securely, easy to peel off in the process of transportation and windowing, can not play a protective role. There are many reasons for this phenomenon, on the one hand, before the extrusion of the film, its surface is not clean, such as water, dust and so on.
To this end, when the aluminum composite panel from the cooling mold out as far as possible to dry its surface water, but also pay attention to workshop dust do not too much, tractor track to keep clean. After achieving the ideal cleanliness, can paste the aluminum composite panel protective film.
On the other hand, aluminum composite panel protective film laminating machine pressure is not enough, or the structure is unreasonable; aluminum composite panel protective film itself is not enough viscosity will also affect the adhesion between it and the object surface. In addition to the appropriate increase of laminating pressure, it is recommended to use a special laminating machine; And the choice of high - quality aluminum composite panel protective film.
There is also a factor will affect the adhesive force between the aluminum composite panel protective film and the object, that is, the aluminum composite panel protective film substrate tensile stress is too small, easy to deformation, or laminating machine rotation part of the action is not flexible, resulting in the film in the process of adhesion by too much stretch and deformation.
After such a protective film of the aluminum composite panel is affixed to the surface, the film will shrink due to the stress generated by stretching. When the shrinkage force is greater than the stripping force, the film will peel off automatically. In view of this situation can be used to stretch the larger protective film or composite protective film; In addition to often lubricate the film sticking machine rotation part, so that it is flexible rotation.
