Find here details of Micro Mineral Fiber Ceiling Board. We are a professional China Concealed Mineral Board Manufacturer.

The main surface treatment of the ceiling is: laminating, rolling and spraying, of which the laminating board is the best.

The market has a lot of ceiling surface treatment, also called film, but it is a kind of film in China. The formed plate is called plastic coated film. There is also a pearl plate, the surface looks like a laminate, but it is not a film at all. It is only used in the spray coating to add pearlescent powder to the paint for spraying. This kind of board is prone to chromatic aberration, and it usually changes color after two or three years.

The roll-coated board is a composite metal sheet with a primer and topcoat on the front and a painted back.

Spray plate surface flow:

Semi-finished products - degreasing - cleaning - chromizing - drying (cooling) - electrostatic powder coating - curing, cooling - lower parts and inspection - packaging into the warehouse.

The surface of the sprayed board with good market surface is sprayed with “epoxy resin” electrostatic powder. The adhesion is grade 1, the gloss is 18 degrees, no color difference, no bubbles, no particles, and weather resistance (indoor 10)

The good spraying plate is passivated before spraying on the surface. Any part of the surface is crossed with a sharp blade and drawn into a small grid of 1MM*1MM. It is peeled off with a medical tape, the coating does not fall off, and the surface is washed 100 times without damage.

Roll coating process:

The roll-coated board has a top coat, a primer, and a back coat. The back coat mainly acts as an antioxidant to make it last longer.

Semi-finished products - machine - forming - lower parts and inspection - packaging into the warehouse.

The surface of the roll-coated board is uniform, smooth, no leakage coating, shrinkage, scratching, peeling and other obvious defects. However, there are trace defects such as bubbles, pits, and inclusions on the surface, which are normal phenomena.

Laminate processing process:

The surface treatment and process of the laminating board are the same as those of the pre-coated board, except that the surface of the laminating board is (PVC film).

The surface of the coated board is firmly adhered, and there are obvious defects such as no wrinkles, scratches, falling off, and missing stickers. However, the surface is allowed to have a small amount of defects such as micro wrinkles, irregularities, and the like in 0.2 mm on both sides in the width direction.

From the above, it can be seen that the intrinsic quality of the aluminum gusset plate is determined by the aluminum substrate and the surface treatment process.
