Standard name: impregnated paper laminated wood flooring
Commonly known as: diamond disk
Structure: wear-resistant layer, decorative layer, high-density base material layer, balance (moisture-proof) layer.
Features: wide application range, pollution resistance, good acid and alkali resistance and maintenance-free.
What is laminate flooring?
Laminated flooring is generally composed of four layers of materials, namely, wear-resistant layer, decorative layer, high-density substrate layer and balanced (moisture-proof) layer. Qualified laminate flooring is made of one or more layers of specially impregnated thermosetting amino resin. Covered on the surface of high-density board and other substrates, the back has a balanced moisture-proof layer, and the front has a decorative layer and a wear-resistant layer, which are hot-pressed.
Strengthening floor classification
1, thickness from thin to thick (more than 8 mm is about 12 mm).
From the point of view of environmental protection, thin is better than thick. Because it is thin, less glue is used per unit area. Thick, the density is not as high as thin, and the impact resistance is similar, but the foot feel is slightly better. In fact, there is not much difference. In fact, there is no difference between the thickness and quality of these two floors. The key is to look at personal choice.
2. There are standard, wide and narrow plates in specifications.
Standard: The standard width is generally 19 1- 195mm. The length is about 1200 and 1300. Wide plate, length greater than 1200mm, width about 295mm. Narrow board, with a length of 900- 1000 mm and a width of about1000 mm, is similar to the specifications of solid wood flooring, and most of them are called imitation solid wood flooring.
Most members of the European Floor Manufacturers Association have adopted this standard specification. Still like this. China imported the most advanced laminate flooring processing line in the world, and also adopted standard specifications. In other words, the products of large-scale laminate flooring manufacturers that import assembly lines are still standard specifications. There are many dealers in the market who advertise that their products are imported. They often say that "imported products do not have wide plate specifications, and the thickness is around 12mm". Should be the vast majority of imported floors, there is no wide plate specifications and thickening size.
Wide plate: the specification of wide plate was invented by Chinese laminate flooring processing enterprises in order to meet the needs of consumers. Its advantages look generous and there are relatively few gaps in the floor. Most of them are thickened, that is, about12 mm. Generally, the decorative paper on the surface is made in China, with many color changes and great elasticity. The disadvantage is that the color difference is relatively large, and the anti-ultraviolet ability of decorative paper is almost poor.
Narrow plate: Narrow plate specification is also a characteristic of our country. The solid wood floor looks generous, too expensive and has poor stability; China's flooring manufacturers have made imitation solid wood flooring. Look at its specifications, as cheap and stable as solid wood flooring. The V-shaped groove made of four sides can really be confused with the real one, and the thickness is basically around12 mm. It has been put into practice in the market for less than a year and is very popular.
3. From the surface coating, there are alumina, melamine and piano paint.
Alumina: Standard laminate flooring surfaces should all contain alumina wear-resistant paper. There are 46 grams, 38 grams, 33 grams, and even lower ones. Spray aluminum oxide directly on decorative paper. According to the national regulations, the wear-resistant revolution of indoor reinforced floor surface should be above 6000 revolutions, and only the floor with 46 grams of wear-resistant paper can meet the requirements. 38 grams of wear-resistant paper can reach 4000-5000 revolutions; 33 grams is lower; Just spray alumina directly, which can reach 2000-3000 rpm. If the wear-resistant revolution is low, the material cost is relatively low; Because of its low wear resistance, the tool cost is also low. On the contrary, the cost of high wear-resistant revolutions is much higher.
Melamine: Melamine has a coating on its surface, which is generally used for wallboard and tabletop. , used in places where wear resistance is not high. In the flooring industry, this kind of coated floor is called "fake floor". Its wear-resistant revolution is only 300-500 revolutions. If the use intensity is high, the decorative paper on the surface will wear out in two or three months. The standard laminate flooring will not have such problems in normal use 10 years. This kind of floor decoration paper has no wear-resistant layer. It looks beautiful and clear. It feels smoother with your hands. This is where laymen are easily fooled.
Piano paint surface: The surface of piano paint is coated, which is actually the reinforced floor paint used on the surface of solid wood floor. This is just a bright paint. The wear resistance of this coating is far from that of alumina surface. Its wear resistance is low, and solid wood flooring is developing towards high wear resistance. Unless you really like this surface coating.
4. From the characteristics of the floor, there are crystal, relief, locking, mute, waterproof and so on.
Crystal surface: basically flat. Easy to take care of, easy to clean.
Relief surface: Seen from the front, it is no different from the crystal surface. From the side, if you touch it by hand, there are wood grain patterns on the surface.
Locking: at the joint of the floor, locking is adopted to control the vertical displacement and horizontal displacement of the floor; The original tongue-and-groove floor, also known as tongue-and-groove floor, can only control the vertical displacement of the floor. No matter how early the wooden floor block is, there is no mortise and tenon at the joint, so the displacement can't be controlled, so it is inconvenient for the floor block to tilt up and stumble when walking.
Mute: that is, add cork cushion or other similar cork cushion on the back of the floor. After using the cork floor mat, the noise of stepping on the floor can be reduced by more than 20 decibels (quoted from cork floor mat factory), which has the effects of increasing foot feeling, sound absorption and sound insulation. This will play a positive role in improving the comfort of laminate flooring. It is also a direction for the future development of laminate flooring.
Waterproofing: coating waterproof resin or other waterproof materials on the tongue-and-groove of the reinforced floor, so that the moisture and moisture outside the floor are not easy to invade and the formaldehyde inside is not easy to release, so that the environmental protection and service life of the floor are obviously improved; Especially in the case of large-scale laying, it is not convenient to leave expansion joints and battens, which can prevent the floor from arching and reduce the contraction joints of the floor.
To sum up, the relief is really beautiful; If you use the same number of grams of wear-resistant paper, the wear-resistant degree of the crystal is relatively high; Silent feet feel really good, but more expensive; Waterproof, cost-effective, not many people know its function.
Chamfering and painting: a processing technology, in which the upper edge of the floor is cut off, and then the color of the base material is covered with paint to make the edge color more layered, similar to the solid wood floor, so it is deeply loved by consumers. After chamfering and painting, there is a shallow crack between the plates, which is easy to accumulate dust and inconvenient to clean. A board without chamfering will not have this problem.
Die press plate: A notable feature of the die press plate is that the upper edge of the plate has a downward arc depression, and the two plates are closely combined after splicing, but there is a small groove, which is called a U-shaped groove in the industry. In most cases, this kind of board is reinforced floor. One of the great advantages of the die plate is that it is easy to clean, and the dust in the small ditch is very convenient to clean, just wipe it with a rag or mop.
Strengthen the characteristics of the floor
1. Wear-resistance: The surface layer of the reinforced floor is a wear-resistant layer, which is composed of evenly distributed alumina. The "wear-resistant revolution" reflecting the wear resistance of reinforced flooring is mainly determined by the density of alumina. Generally speaking, the denser the alumina distribution, the higher the wear-resistant revolution of the floor. However, wear resistance does not mean durability. When choosing durable laminate flooring, we really need to pay special attention to whether the concave and convex grooves of the flooring are tightly meshed, whether the base material is firm, whether the formaldehyde content is too high, and whether the color is true and natural.
2. Various colors: the colors are fashionable and can simulate various natural or artificial patterns. Compared with traditional solid wood flooring, it is larger in size. Abundance: The decorative layer of reinforced floor is generally simulated by computer, which can simulate the wood grain of all kinds of wood and even imitate stone to create unique patterns that are not found in nature.
3. Easy to handle: Because the wear-resistant layer on the reinforced floor surface has good wear resistance, pressure resistance, impact resistance, fire resistance, flame retardancy and chemical pollution resistance, in daily use, you only need to clean it with a wringing rag, mop or vacuum cleaner. If the floor has oil stains or stains, wipe it with a cloth dipped in detergent.
4. Convenient installation: Because the four sides of the reinforced floor are provided with tenons and grooves, it is only necessary to match the tenons and grooves to form an accurate bite during installation. The paved floor has good overall effect, uniform color and good visual effect. At the same time, the reinforced floor can be directly installed on the ground or other floor surfaces, and there is no need to beat lumbricus. In addition, the reinforced floor can be laid from anywhere in the room, which is simple and fast.
5. Impact resistance: Compared with the solid wood floor, the wear-resistant layer on the surface of the reinforced floor has been specially treated to achieve high hardness, even if it is scraped with sharp hard objects such as keys, it will not leave traces. The biggest advantage of this advantage is that in order to protect the floor in daily life, there is no need to be timid. But also has high flame retardancy, strong pollution resistance and corrosion resistance, good compressibility and impact resistance.
6. Excellent cost performance (low price): The laminate flooring is composed of wear-resistant layer, decorative layer, base material and balance layer. The wear-resistant layer, decorative layer and balance layer are all printed by hand, and the base material is made of fast-growing wood, so the cost is lower than that of solid wood floor, and it can be produced on a large scale with high cost performance.
