The first step in protecting the film is to use an aluminum composite plate and a suitable protective film. Consider the variety of the aluminum composite plate, the coating material, and the smoothness of the surface when choosing the protective film.
According to their applications, aluminum composite sheets are classified as curtain wall aluminum-plastic panels and interior wall aluminum-plastic panels. Because the outer wall panel is exposed to ultraviolet light after installation, the protective film is easily removed.
However, wiping off the glue after the glue has been removed is extremely difficult; even if it is wiped off, the aluminum-plastic board surface will have a significant color difference. As a result, a black-and-white protective film with a good anti-ultraviolet effect is required.
Some black-and-white film substrates manufactured by protective film manufacturers are of poor quality. Under the light, the black and white film still transmits light, there is no anti-ultraviolet effect, and the protective film does not prematurely age under outdoor sunlight conditions. It collapses into a broken shape, posing difficulties for the builder.
Aluminum composite sheets are classified into two types: According to the material of the paint coatings, polyester aluminum composite panels and fluorocarbon aluminum composite panels exist.
Metal paint surfaces and non-gold alloy paint surfaces are the two broad categories. Because of the differences in paint material and structure, different requirements for the thickness and viscosity of the protective film glue are imposed.
If the protective film's glue property is incorrectly selected or the glue quality is unstable, it will cause many problems for the user when used, such as sticking, curling, or sticking up and tearing down during the shelf life.
The viscosity of the surface protective film should be chosen based on the smoothness of the material's surface:
The material's surface is smooth and smooth. The protective film's viscosity is low, the material's surface is rough, the coated surface is relatively thick, and the viscosity of the protective film is high.
On the contrary, if you use it incorrectly, you will experience a phenomenon in which the viscosity is either too weak or too strong to be exposed.
A small sample of aluminum-plastic plate protective film should be tested first. Determine whether the adhesive used to select the surface protective film is compatible with the decorative material's surface coating. Inadequate chemical properties can damage the surface of the decorative material because the adhesive of the surface protective film is not self-adhesive for universal use.
An aluminum composite panel is a new type of wall decoration panel with numerous applications in interior and exterior decoration, particularly outdoor decoration.
All of the signboard aluminum composite panels on the market are wrapped in a protective film. Each ACM board manufacturer's logo appears on the protective film. But do you know what function the protective film serves?
The protective film's most important function is to ensure the quality of the surface of the aluminum composite panel and to apply a thin plastic film to the surface to protect the produced aluminum composite board in handling, inventory, transportation, processing, installation, and so on. The series was not harmed in any way during the process.
There are many requirements for the protective film to truly protect the aluminum composite sign board, such as:
It must have a certain adhesive force and adhere well to the surface of the aluminum-plastic plate. After application, the paste does not pollute or corrode the surface to be adhered to, nor does it cause a chemical reaction with the surface to be adhered to.
It is weather-resistant, easy to peel off when uncovering, and does not leave any residual glue. After bonding, it can be plasticized by drilling, cutting, bending, and so on.
To improve understanding of the protective film's role, it should be noted that the protective film and the packaging film should not be confused. Although the protective film has a packaging effect, it is not the same as the packaging film.
The primary distinction between protective film and packaging film is that protective film not only adheres to the finished product but also protects it from damage during handling and transportation.
More importantly, it is frequently used in the manufacturing process to participate in product processing (such as cutting, hemming, drilling, stamping, and so on).
The aluminum-plastic composite panel plays the following roles in the manufacturing process: first, before being used for slitting, the aluminum-plastic composite panel is protected from being lost when cut.
Second, it is involved in the entire process of product processing and installation by the final customer (decoration, construction engineering company) to ensure that the product is free of smudging and damage.
