Types of composite aluminum

Types of composite aluminum in terms of sheet surface coverage

The paint is applied to the surface of the composite aluminum sheet with different technologies depending on the type of application and where the sheet is installed.

1- D-PE aluminum composite panel

The easiest way to apply paint on the aluminum layer is to apply the paint on the aluminum layer without any protective layer.

This type of sheet is very vulnerable to weather, acid or alkaline conditions, there is no guarantee of its quality on the exterior of the building

In general, it is forbidden to use the exterior of the building but is suitable for interior decoration.

2- PVDF aluminum composite panel

This coating is called a special resin under the name Polyvinyl Din Fluoride.

Due to the polymeric layer as well as the fluorine element, this resin protects the surface of the sheet and its durability and stability against adverse weather conditions, UV

Purple and acidic and alkaline conditions are completely reliable for at least 5 years.

The paint that is applied to the surface of the resin does not apply directly to the aluminum and is then coated with a polyurethane liner

The applied aluminum is then added to the paint layer.

Therefore, PVDF sheets have 4 layers of color.

3- NANO aluminum composite panel

It is similar to PVDF resin except that a third layer is applied to PVDF resin.

Molecular structure is different from ordinary resins.

If the molecular distance of nanotechnology is less than 1–2, this property does not absorb environmental contaminants such as dust and particles.

The oil is suspended in space.

This type of sheet is supplied by Premium Bond factory in Iran and is widely used.

Mid-layer technology segmentation

Depending on the application and sensitivity of the middle layer project, it consists of several materials.

The explanation that polyethylene is generally used in the middle layer of these sheets is generally non-flammable, but depending on the sensitivity of the project and the presence of flammable materials near these sheets, the middle layer A2, B1 is used. It should be noted that standard A1 applies to homogeneous (non-composite) fireproof materials.

Recycled polyethylene

New polyethylene

Fireproof middle layer B1

A2 fireproof middle layer, usually made of aluminum hydroxide or other minerals.
