How to choose aluminium composite plate protective film?

0 Comments

In order to protect the aluminium composite plate , a suitable protective film is the first step to protect the film. When selecting the protective film, factors such as the variety of the aluminium composite plate, the material of the coating, the smoothness of the surface.

Variety of aluminum composite panels

aluminum composite sheet color

The color of the aluminum composite panel depends on the coating on the surface

 

Aluminum composite sheet can be divided into curtain wall aluminum plastic panels and interior wall aluminum plastic panels according to their applications. Since the outer wall panel is exposed to ultraviolet light after installation, it is easy to cause the protective film to remove.

However, it is very difficult to wipe off the glue after the glue is removed, even if it is wiped off, the aluminum-plastic board surface will have a significant color difference. Therefore, it is necessary to use a black and white protective film having a good anti-ultraviolet effect.

It should be noted that some black and white film substrates produced by protective film manufacturers are of poor quality. Under the light, the black and white film still has light transmission, no anti-ultraviolet effect, or premature aging of the protective film under outdoor sunlight conditions. It fall into a broken shape, which brings difficulties to the builder.

Aluminum composite panel material of coating

Aluminum composite sheet can be divided into two categories: polyester aluminum composite panels and fluorocarbon aluminum composite panels according to the material of paint coatings.

Each of them can be roughly divided into metal paint surface and non-gold alloy paint surface. Due to the difference in the material and structure of the paint, different requirements are imposed on the thickness and viscosity of the protective film glue.

If the glue property of the protective film is improperly selected or the glue quality is unstable, it will bring many problems to the user when using them, such as sticking, curling or sticking up and tearing down during the shelf life.

Smoothness of the surface of the acp panel

The viscosity of the surface protective film should be selected according to the smoothness of the surface of the material:

The surface of the material is smooth and smooth. The viscosity of the protective film is low, the surface of the material is rough, the surface of the coated surface is relatively thick, and the viscosity of the protective film is high.

On the contrary, if you choose to use it improperly, it will result in a phenomenon that the viscosity is not strong or the viscosity is too strong to be uncovered.

How to choose aluminium composite plate protective film

The choice of aluminum-plastic plate protective film should be tested first with a small sample. Determine whether the adhesive that selects the surface protective film is compatible with the surface coating of the decorative material.

Because the adhesive of the surface protective film is not a self-adhesive for universal use. Inadequate chemical properties can damage the surface of the decorative material.
