Precautions for the surface film of stainless steel decorative color plates, especially stainless steel elevator plates

The stainless steel decorative color plate processed by various processes will have a protective film on the surface. This layer of protective film mainly protects the surface of the sheet and ensures that the surface can be intact in the next processing. If the film is not properly applied, or the quality of the film is not good enough, it will cause damage to the surface of the board. Therefore, several aspects should be paid attention to when sticking the film;

First of all, the film with a reasonable viscosity should be selected. Common adhesive films include black and white film (the adhesive surface is black), blue film, transparent film, etc. The commonly used thickness is 5 to 7 silk, and the viscosity is from low to high viscosity. Customers can choose according to their own needs.

In winter, the viscosity must be increased, and in summer, the viscosity can be decreased. These choices are mainly to prevent two phenomena: one is that the film is not viscous enough to automatically fall off, and the other is that the viscosity is too large, which makes it difficult to tear the film, or even degumming.

Secondly, the quality of the film is also the key point. In terms of production process, it is difficult to avoid the rubber particles in the film, but the rubber particles have a great influence on the subsequent stamping and stretching of the elevator decorative board, so it is necessary to make requirements on the size and quantity of the rubber particles. Customers can Make standards according to your own quality requirements. Similarly, the inclusions, bubbles and wrinkles in the film will affect the quality of the product. If the customer's requirements are really high, imported film can be selected.

The lamination process is also very important. If the film is not passed, it will also cause bubbles or wrinkles in the film. These quality problems are related to the operation level of the film machine and the staff. The processing center should avoid similar situations.

It is worth mentioning that the film also has a shelf life. In particular, it should be noted that the adhesive film method of the stainless steel elevator board. Because the surface requirements of stainless steel elevator panels are very high, the film must be torn off in a short period of time. And it is necessary to prevent the stainless steel elevator board with adhesive film from being exposed to the sun or placed in a high temperature environment. The above measures are to avoid the phenomenon of degumming. Once degumming occurs, the adhesive film will be difficult to tear off, and there will be residual adhesive left on the board. In case of residual glue, it can be scrubbed with organic solvents, but scrubbing is very difficult and will leave imprints on the board that are difficult to remove.
