Composite floor classification and selection criteria

Classification of a composite floor

There are two main types of composite flooring on the market today: one is solid wood composite flooring; the other is reinforced laminate flooring. These two types of laminate floorings have different characteristics and require different requirements for use and maintenance.

Solid wood composite flooring has both natural and comfortable flooring, comfortable footwork, and good insulation properties. It also overcomes the insufficiency of solid wood flooring due to the shrinkage of monomers. Now that the living environment is no longer deteriorating, countries all over the world attach great importance to the protection of forest resources. Solid wood flooring can save precious wood resources compared to solid wood flooring. In addition, solid wood flooring is easy to install, and it is not necessary to use keels in general. However, it requires ground leveling.

Solid wood composite floor can be divided into three categories of solid wood composite floor, multi-layer solid wood composite floor, fine wood composite floor three categories, more than three layers of solid wood composite floor in the room decoration.

The three-layer structure solid wood composite floor is formed by three layers of solid wood, and the surface is made of high-quality hardwood specifications. The commonly used tree species are ash, birch, beech, beech, maple, and cherry. The middle is a cork board, and the bottom layer is a rotary board, arranged in a crisscross pattern. This structural composition makes the three-layer solid wood composite floor not only has the advantages of ordinary solid wood flooring, but also effectively adjusts the internal stress between the wood, and improves the shortcomings of the wood with large changes in dry humidity during the season.

The solid wood floor has a good foot feeling, natural texture and color, and slightly less hardness. And because it is natural, textures and colors vary greatly. Wooden keels are required when paving, and the price is relatively high.

The high-strength composite flooring has high hardness, good wear resistance, simple and convenient pavement, and low price, but the foot feels slightly worse.

Solid wood flooring absorbs the advantages of the above two, the price is between the two, but the hardness is the worst of the three.

Two how to choose composite floor

When selecting composite flooring, it is necessary to ensure that the major indicators are qualified. These indicators and national standards are:

1. Thickness of water-absorbing thickness: The water-absorption thickness expansion rate of excellent products is below 2.5%; the water-absorption thickness expansion rate of first-class products is below 4.5%. With water bubbles, the quality of water absorption is poor.

2, the surface wear resistance: the floor because there is no wear-resistant layer or wear resistance is very low and is called false floor, this floor surface and real composite flooring no difference

After sanding several times with sandpaper, you will find that the decorative pattern is polished and immediately white. This floor is a fake floor.

The service life in public places will generally not exceed six months.

The stronger the grinding, the price is also more expensive. The number of wearable revolutions in public places is above 9000 rpm; if you have a large population in your home, you don’t pay much attention to maintenance, you can choose some higher wear resistance; but if you pay more attention to the maintenance of the floor, the floor is subject to strong and hardware wear. With fewer opportunities, it may be more economical to choose a bit lower wear resistance. Family wear-resistant rotations can be more than 6,000 rpm. . Can be rubbed with sandpaper, poor quality is easy to find. The wear resistance of composite flooring mainly depends on the coating of aluminum oxide crystals (commonly known as gemstones). The higher the aluminum oxide crystal content per unit area of ​​the floor, the higher the degree of wear resistance.

3, formaldehyde emission: A grade of formaldehyde release value of 9mg/100g or less. B pole 9 to 40 mg / 100 g, to reach the B level can be used. The quality of the glue determines the degree of contamination of the laminate flooring, and the quality of the good glue formaldehyde is low.

Ou Dian's floor formaldehyde content is only 5MG/100G, which is lower than the EU standard and ranks first. It has become the first imported green product certified by the China Environmental Labeling Committee.

4, density: the density of qualified products ≥ 0.9g/cm3.

5. Moisture content: The moisture content of the qualified products is in the range of 3.0-10.0%. When people purchase floors, they can check the data through the product inspection certificate and check whether the outlet is straight. The completeness of the mouth is directly related to the life of the floor.

7 The surface of the impregnated adhesive film should not have dried flowers, opaque white dots, wet flowers, spots, scratches, and indentations. The tongue and tongue and groove around the surface should be kept intact. The length, width, and thickness of the composite plate should be the same as those of the product introduction. You can take as many pieces of composite flooring as you like to observe after combining them. See if the splicing seams of boring heads are uneven or not. Assemble by yourself to observe whether the jaws and grooves are tightly combined and feel smooth. The middle layer of parquet can not only increase the feeling of foot, but also prevent the expansion and deformation of the floor. The thickness should be 7-10mm. In the material selection, the quality of rubber wood and pine wood in the middle layer is higher, followed by willow wood. Multi-layer solid wood composite floor often uses multi-layer plywood as the base material, and the surface decoration panel is mostly made of hardwood laminations, and the thickness is usually between 0.2-0.8 mm.

8 The middle layer of parquet can not only increase the foot feeling, but also prevent the expansion and deformation of the floor. The thickness is suitable for 7-10mm. In the material selection, the quality of rubber wood and pine wood in the middle layer is higher, followed by willow wood. Multi-layer solid wood composite floor often uses multi-layer plywood as the base material, and the surface decoration panel is mostly made of hardwood laminations, and the thickness is usually between 0.2-0.8 mm.

Consider the size of the living area. Under normal circumstances, if the room is large and the lighting is sufficient, a darker, thicker texture wood floor should be selected to make the relatively large room relatively compact. On the other hand, the room with a small area can use light colors and textures. The wooden floor gives a sense of openness and will make the smaller room appear spacious.

9 Consider the different functions of each room, different rooms can choose to use different colors of wood flooring. The living room is the most open place in the family, and it is also the main place for family members to conduct daily activities and receive guests. Therefore, it is advisable to use high transparency and soft colors to create a clear, harmonious and elegant atmosphere; the bedroom is for rest and relaxation. Place, should use warm colors or some neutral colors of the floor, giving a quiet, comfortable feeling; Children's room is the place for children to sleep, study, and living, should be simple, cheerful, clear, using light and bright colors will be good; The study room is the place where the owner of the room works and learns. The environment should have a strong cultural atmosphere, and the color used should also be a stable dark floor.

Consider the harmonization of floor colors and other room colors. Other bedroom colors include ceilings, walls, furniture colors. The color of ceilings and walls is usually applied with light colors; because the furniture color dominates the indoor environment and is chosen with the preferences of the homeowners, the choice of ground color usually follows the harmony with the furniture tone and the color of the wall. Echoes the principle to match.
