Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in FIG. 1, the high haze roller of the present application is a schematic structural view, and comprises a roller body 100 having uniformly distributed pits 110 on the roller surface of the roller body 100, wherein the roller body 100 has a roller surface roughness RA of 0.1 μm and a depth of 0.1. mu.m.
When the PE film is laminated on the paper surface, the PE film and the paper are simultaneously fed below the roller body 100, the roller body 100 contacts the PE film, and a heating medium needs to be introduced into the roller body 100 to heat the roller body 100, thereby ensuring that the PE film is laminated on the paper surface in accordance with the requirements. Under the process, the PE film is easy to adsorb on the roller body 100 when the PE film is discharged from the roller, so that the linear speed of the roller body 100 needs to be controlled within 50-80 m/min, and once the speed exceeds the speed range, the yield of the PE film composite is greatly reduced.
The application does not start with the traditional improvement of the high-haze roller, but rather controls the roughness of the roller surface to be one degree, the roughness RA is 0.1 mu m, the depth is 0.1 mu m, the optimal condition is adopted, and the linear speed of the roller body 100 can be directly increased to 400m/min under the condition. Correspondingly, the roughness RA can be set to be any value between 0.05 and 0.5 μm, the depth of the corresponding concave point 110 can be set to be any value between 0.05 and 0.5 μm, and the linear speed of the roller body 100 can exceed 300m/min within the range.
Through analysis, in the film condensation process of the roller body 100, a certain amount of air can be pressed into the concave points 110 at the moment of contact with the PE film, and the air pressed into the concave points 110 can form an air gap dielectric layer between the roller body 100 and the PE film, so that the adsorption effect between the PE film and the roller body 100 when the PE film is discharged from the roller is greatly improved, the PE film is more easily separated from the roller surface of the roller body 100, and the linear speed of the roller body 100 can be improved.
The concave points 110 on the roll surface of the roll body 100 are formed by sand blasting.
Correspondingly, the embodiment also provides a film condensation method, which comprises the following steps: the PE film and paper were fed simultaneously under a press roll at 220 c, which was the roll body 100 described in the above example.
The PE film is not limited to the PE film, but may be other polymer film layer materials, such as PET.
The paper is not limited to paper, and may be other materials that can be used as a base layer of a composite material, such as nonwoven fabric.
It is noted that, in this document, relational terms such as first and second, and the like, if any, are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
