1) Bottom layer: made of polyester material to prevent moisture.
2) Base layer: generally made of MDF, depending on the density of the MDF, it is also divided into low density board, medium density board and high density board.
3) Decorative layer: It is a special paper printed with a specific pattern (mainly simulated texture), and then immersed in a trimeric hydrogen ammonia solution. After chemical treatment, it is chemically stable after heating with tripolyhydrogen ammonia. The chemical reaction characteristics make this paper a beautiful and durable decorative layer.
4) Wear-resisting layer: It is an anti-wear agent composed of a layer of Al2O3 uniformly pressed on the surface of the reinforced floor. The content of aluminum oxide and the thickness of the film determine the number of revolutions of wear. The number of wear-resistant layers per square meter containing about 30 grams of aluminum oxide is about 4000 revolutions, the wear resistance of 38 grams is about 5000 revolutions, and the wear resistance of 44 grams is 9000 revolutions. Left and right, the greater the content and the degree of film, the higher the number of revolutions, the more wear resistant.
Composite flooring is generally composed of four layers of composite materials: the bottom layer, the substrate layer, the decorative layer and the wear layer. The number of revolutions of the wear layer determines the life of the composite floor.
