Analysis of the reasons for peeling of aluminum plastic boards:

The aluminum plastic plate is a new material made of aluminum plates that are treated and coated with paint, polyethylene, and polypropylene plastic mixed as the core layer. Because aluminum -plastic boards are composed of two materials (metal and non -metal) that are completely different in nature, it not only retains the main characteristics of the original composition materials (metal aluminum, non -metallic polyethylene plastic), but also overcomes the shortcomings of the original composition materials , And then obtaining many excellent materials, such as luxury, gorgeous decorative, weather resistance, corrosion resistance, fire resistance, fire prevention, moisture -proof, sound insulation, insulation, seismic resistance; Installation and other characteristics, these features have broadly opened the broad prospects for aluminum -plastic boards. The production of aluminum -plastic composite plates is very simple to laymen, but in fact it is a new product with high technical content. Therefore, the quality control of aluminum -plastic board products has certain technical difficulties.

The following mainly talks about the factors that affect the peeling strength of the aluminum -plastic composite panel.

1. The quality of aluminum foil itself:

Although this is a more hidden problem, it is already reflected in the quality of aluminum -plastic boards. On the one hand, the thermal treatment process of aluminum materials, on the other hand, some aluminum plates and producers are not strict with quality control when using recycled waste aluminum.

This requires the producers of aluminum plastic panels to evaluate the material producers in various aspects to determine the establishment of business exchanges to ensure the quality of the material after the qualified contractor.

2. Preliminary treatment of aluminum plates:

The mass of the cleaning and layer of aluminum plate directly related to the composite quality of aluminum -plastic plates. The aluminum plate must first be cleaned and removes surface oil pollution impurities, so that the surface forms a dense chemical layer, so that the high molecular membrane can produce a good bonding.

However, some manufacturers have not controlled the temperature, concentration, processing time, and update of processing liquid during the processing of the processing process, which affects the quality of cleaning.

What's more, some new manufacturers are used directly without any preliminary treatment of aluminum plates. All of these will lead to poor composite quality and low or unstable peeling strength of 180 °.

3. Selection of core materials:

Because the bonding of polymer membrane and PE is the best effect compared with other plastics and is moderate price, non -toxic and easy to process. So the core material uses PE. In order to reduce the cost of the cost, some small manufacturers choose PVCs with poor bonding effects and burning, or use PE recycling materials or mix with PE raw materials with the lower corner materials.

In this way, the composite temperature will be different due to the different models of PE, aging, etc., and the final surface is unstable composite quality.

4. Selection of polymer membranes:

Polymer membrane is a adhesive material with special performance, which affects the main factor of complex quality. High molecular membrane has two sides, and three layers are squeezed together.

On one side is to bond with metal, the other side is bonding with PE, the middle layer is the PE substrate, and the nature of the two sides is completely different. The price of materials on both sides is different. Materials to be tied with aluminum shops need to be imported, and the price is expensive.

The materials that are fused with the PE can be produced in China. Therefore, some high -molecular membrane manufacturers make great articles and use PE fusion materials to reduce materials to make huge profits. The use of high molecular membranes is directed, and the front and back cannot be changed. High molecular membrane is a self -solving film, which will cause pseudo -composite.

Early intensity and long time, due to weathering impact, reduce intensity, even bubble or open glue.

The skeleton made of such metal materials is not much higher than the wooden keel and high -density plate, which can indeed ensure the quality of the project.

4. Aluminum -plastic plate gel sewing is neat:

When the aluminum plastic board is decorated on the surface of the building, there are generally a certain width gap between the plates. For aesthetic needs, black sealing glue must be filled in the gap.

In order to save time, some construction personnel do not use paper gum to ensure that the glue is neat and regular, but instead use the protective film on the surface of the aluminum -plastic plate as a substitute. Because the aluminum -plastic plate is cut, the protective film will cause to tear to varying degrees, so it is not possible to use it to protect the tape alternative.
