Composite wood flooring is generally composed of four layers of composite materials, namely wear layer, decorative layer, substrate and bottom layer.
The bottom layer of the reinforced composite wood floor is a moisture-proof layer. Polyester materials are generally used to block the moisture and moisture from the ground, thereby protecting the floor from the wetness of the ground and balancing with the above layers.
The base layer is the main part of the laminate wood flooring. Most laminate flooring uses high density fiberboard as the substrate. Because the density plate has many advantages that the original wood does not have, the structure of the density plate is uniform and the particles are evenly distributed. The quality of the MDF is mainly distinguished by its density value. Above the substrate layer is a decorative layer, that is, a pattern layer, which is made of a specially processed paper material. The general procedure is to immerse this special paper with a certain pattern into a solution of trihydric ammonia, and after chemical treatment, the chemical properties after the reaction is heated by using a trihydridohydrogen is stable, and no chemical reaction occurs. Make this paper a beautiful and durable surface paper, this surface paper itself has a resistance of 400 rotation, and it is waterproof and UV-resistant without fading.
The so-called wear layer is a layer of anti-wear agent uniformly pressed on the surface of the laminate floor. This anti-wear agent is formed by uniformly distributing Al2O3 in a thin film and has good wear resistance. The intrinsic factors affecting the wear resistance are mainly the content of aluminum oxide and the thickness of the surface film. In today's market, the wear-resisting layer of the laminate flooring is mainly divided into four grades. The abrasion resistance of the wear-resistant layer containing about 3Og of aluminum oxide per square meter should be around 40000 rpm. The abrasion resistance of the floor of 38g should be at 50000, the abrasion resistance of the floor of about 44g should be around 9000, and the abrasion resistance of the floor of about 62g can be up to 180,000 turns.
Basically, laminate flooring is composed of the above four layers, which results in the floor's wear resistance, moisture resistance, relative stability, and aesthetics comparable to solid wood flooring. Solid wood multi-layer flooring, solid wood, it is different from the laminate flooring with high density fiberboard as the core material. Generally speaking, a solid wood multi-layer floor is composed of about 5 layers of solid wood. Each layer of wood texture is vertically aligned with two adjacent layers of wood. This eliminates the internal stress of the wood and basically eliminates cracking and cracking of the floor. Disadvantages. Solid wood multi-layer flooring, most of them use a variety of valuable natural wood as a surface layer, and adopt advanced technology to wear-resistant polyurethane paint through the press through the gap in the wood, and then cured, so that paint and wood are integrated into one.
Solid wood multi-layer flooring not only has the natural beauty of natural wood and comfortable foot feel, insect resistance, moisture resistance, etc., but also has the characteristics of strengthening the composite floor not easily deformed, easy installation, is very popular, and the market prospect is promising.
