When selecting a composite floor, it is important to ensure that the main indicators are qualified. These indicators and national standards are:
1. Water absorption thickness expansion rate: The water absorption thickness expansion ratio of superior products is less than 2.5%; the water absorption thickness expansion rate of first-class products is below 4.5%. Water bubbles, the quality of water is poor.
2, surface wear resistance: the floor is called a fake floor because there is no wear layer or the wear resistance is extremely low. This kind of floor surface is indistinguishable from the real composite floor, but after sanding it several times, it will be found that the decorative pattern is polished and immediately whitish.
The service life in public places generally does not exceed six months.
The stronger the wear, the more expensive the price. The wear resistance of public places is more than 9000 rpm; if you have a large population in your home, you should not pay attention to maintenance, you can choose higher wear resistance; but if you pay more attention to the maintenance of the floor, the floor is strong and the hardware is worn. If there are fewer opportunities, it may be more economical to choose a relatively lower wear resistance. The household wear-resistant number of revolutions can be more than 6000 rpm. It can be rubbed with a sandpaper, and the quality is very easy to find. The wear resistance of composite flooring depends mainly on the coating of Al2O3 crystals (commonly known as gemstones). The higher the content of the aluminum oxide crystal per unit area of ​​the floor, the higher the wear resistance.
3. Formaldehyde emission: The formaldehyde emission of the grade A product is within 9mg/100g. B pole 9 to 40 mg / 100 g, can reach the B grade. The quality of the glue determines the pollution level of the laminate flooring, and the quality of the glue is low.
The “Ou Dian†floor has a formaldehyde content of only 5MG/100G, which is lower than the EU standard and ranks first. It has become the first green product to be certified by the China Environmental Labeling Committee.
4. Density: The density of qualified products is ≥0.9g/cm3.
5. Moisture content: The moisture content of the qualified product is in the range of 3.0-10.0%. When people buy the floor, they can check the data through the product inspection certificate.
6, pick the mouth is straight. The integrity of the mouth is directly related to the life of the floor.
7. The surface of the impregnated film paper finish should not have opaque white dots, wet flowers, stains, scratches and indentations, and the surrounding tongues and tongues should remain intact. The length, width and thickness of the composite board should be the same as the product introduction. You can take multiple pieces of composite floor to make a joint observation and see if the joints combined with the hoe are high and low, and the seams should be rigorously take multiple floors. Self-assembled to observe whether the sputum and groove combination is tight and the hand feel is flat. The middle layer of the parquet can not only increase the feel of the foot, but also prevent the expansion and deformation of the floor. The thickness is preferably 7-10mm. In the selection of materials, the middle layer is higher in quality grade of rubber wood and pine, followed by willow wood. Multi-layer parquet is often based on multi-layer plywood, and the surface decorative panels are mostly laminated with hardwood sheets, and the thickness is usually between 0.2 and 0.8 mm.
8, the middle layer of solid wood composite floor, not only can increase the sense of foot, but also prevent the expansion and deformation of the floor, the thickness is 7-10mm is appropriate. In the selection of materials, the middle layer is higher in quality grade of rubber wood and pine, followed by willow wood. Multi-layer parquet is often based on multi-layer plywood, and the surface decorative panels are mostly laminated with hardwood sheets, and the thickness is usually between 0.2 and 0.8 mm.
Consider the size of the living room area. Under normal circumstances, if the room is large and the lighting is sufficient, the darker and coarser texture of the wooden floor should be used to make the larger room relatively compact. On the contrary, the small room can be light and fine. The wooden floor gives a sense of openness and makes the smaller room look wider.
9, considering 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 home, and it is also the main place for family activities and reception of 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. The place should be warm or some neutral color to give a quiet and comfortable feeling; the children's room is the place where the child sleeps, learns, and lives. It should be simple, cheerful, and clear. It is good to use light and bright colors. 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 use a solid dark floor.
10. Consider the coordination of floor color and other room colors. Other room colors, including ceilings, walls, and furniture, are usually applied in light colors. Because the color of the furniture dominates the indoor environment and is chosen according to the preferences of the owner, the choice of ground color is usually followed by the color of the furniture. It is unified and matched with the principle of wall color.
