There are a variety of production processes of Aluminum Composite Panel, according to the composite process of plastic core plate and two-sided aluminum plate can be divided into cold compounding and hot compounding; It can also be divided into continuous compound method and intermittent compound method.

The production of Aluminum Composite Panel process is the first cleaning aluminum coil. Due to the needs of the process in the production of aluminum rolling material, the surface is coated with lubricants and antioxidants, in the transport will also adhere to some dirt, these will affect its adhesion, so it must be cleaned. After cleaning and chemical treatment, a compact chemical protective film will be produced on the surface of aluminum rolling material. This layer of chemical film can improve the oxidation resistance and extend the life of the film.

                                                         Aluminum Composite Panel

The general cleaning process is as follows: aluminum coil spray degreasing washing neutralization chemical treatment washing drying cooling winding. The cleaned aluminum coil is fed into the coating machine, and the outer surface of the aluminum coil is coated with high performance fluorocarbon resin.

Aluminum Composite Panel Manufacturer shares the process flow is as follows:

Aluminum coil material feeding coated fluorocarbon coating hot air circulation paint cooling laminating cutting winding.

Exterior aluminum panels to be coated with two layers of paint and primer. The topcoat of exterior wallboard is the fluorocarbon resin coating with extremely high weathering resistance, namely polyvinylidene fluoride (PVDF), its outstanding anti-ultraviolet performance and anti-environmental pollution make the surface of protected aluminum rolling material keep gorgeous color.

The surface of Aluminum Composite Panel can have metallic colour and lustre not only, also can have beautiful marble pattern and colour. Fluorocarbon coatings are usually coated on aluminum rolls by roller coating and then baked at high temperature to dry them. Equipment for continuous production, first primer, then topcoat, and finally surface varnish. Three layers of paint a total thickness of 30 mu m, each layer of paint should be above 200 ℃ baking around 60 s, makes it dry, the baking box after rapid cooling by air cooling machine. Interior panel paint can be epoxy resin, polyester resin and acrylic resin. After the primer, topcoat and surface varnish are coated, a PE protective film shall be immediately pasted on the surface of the coating layer to prevent the surface coating from being scratched during subsequent processing, transportation, circulation and installation.
