Description

BOPP film surface performance detection

Technical Field

The utility model mainly relates to the technical field of film detection, in particular to BOPP film surface performance detection.

Background

Biaxially oriented polypropylene (BOPP) films are generally multilayer coextrusion films, and are prepared by coextrusion of polypropylene particles to form sheets and stretching the sheets in longitudinal and transverse directions; because the biaxially oriented polypropylene film has nonpolar surface, high crystallinity and low surface free energy, the biaxially oriented polypropylene film has poor printing performance and poor adhesion to ink and adhesives, and surface treatment is required before printing and compounding.

In order to make preliminary understanding of the surface properties of the BOPP produced, the surface energy of BOPP films may be detected by using a dyne liquid brush method.

For example, the bopp film surface energy rapid detection platform with the patent number of CN202122377578.7 comprises a table top for fixing the bopp film to be detected; a gradient brush rack is fixed with a plurality of dyne pens with different dyne values; the gradient brushing frame moves horizontally along the table top, so that the dyne pen synchronously brushes the dyne liquid with different dyne values on the surface of the bopp film to be detected.

During the operation of the specific examples, the inventors have found the following drawbacks:

in the prior art represented by the above patent, the dyne pen and the gradient brush holder are clamped in a time manner, so that the disassembling is difficult, and in practical application, the pen point of the dyne pen and the bopp film need to be contacted with each other, if the position of the dyne pen is too lower than the bopp film in the clamped state, the bopp film is easy to puncture in the moving process, and if the dyne pen is higher than the bopp film, a continuous line cannot be written on the bopp film, so that the time spent for installing the dyne pen is relatively long.

The above-described contents are within the technical knowledge of the inventors, and the technical contents in the art are huge and complicated, and thus the above-described contents of the present utility model do not necessarily constitute the prior art.
