When you go to the market floor shop, you will basically sell laminate flooring. There are a lot of comments on how laminate flooring is not environmentally friendly and unhealthy. Not really. If laminate flooring has a soul, he will cry himself out, so why did he produce laminate flooring? Existence is meaningful! Laminated wood flooring has its unique advantages, it has good wear resistance, stability and practicality.
/kloc-in 0/9, the global sales volume of laminate flooring produced by members of European Composite Flooring Association (EPLF) reached 447 million square meters. In all kinds of floors, quantity is unshakable. 20 19 data were exported to 28.2 million square meters in Asia. This message illustrates two points. First, many imported products of laminate flooring are really imported. Second, the price of such a large number of imported laminate flooring is really not expensive. So don't buy expensive friends who strengthen the floor imports.
Professional articles on strengthening floor product structure
1) Wear-resistant layer: mainly composed of alumina (commonly known as corundum), it is a high-hardness compound (hardness is second only to diamond) with strong wear resistance, high temperature resistance and flame retardancy. It is an important condition for wear resistance and service life.
2) Decorative layer: It is composed of melamine impregnated paper and wood grain or other exquisite patterns of rare trees simulated by computer, with rich patterns and diverse colors. Strengthening the decorative layer of the floor is an important embodiment of the floor color and the soul that determines its decorative effect. Pattern design and printing effect will directly affect the aesthetic feeling and quality of the floor. There is a big difference between imported products and domestic products. It depends on a word.
3) substrate layer: wood is crushed and ground into wood fibers, and then made into high-density wood fiber board at high temperature and high pressure. High-density board is the product carrier to strengthen the hardness and strength of flooring products, and its stability is determined by two important indexes, namely, the density of substrate layer and the source and structure of raw materials used in manufacturing. 850kg/m3, European standard high-density board ≥900kg/m) The raw material source and structure of the density board-the density board is made of pure pine fiber, poplar fiber, mixed wood fiber and secondary recycled waste fiber. In short, environmental protection depends on it.
4) Balance layer: made of kraft paper impregnated with resin, with certain strength and thickness. So it can be well balanced, moisture-proof and prevent the floor from deformation. Balance layer, also known as "moisture-proof balance layer", as its name implies, has moisture-proof balance function, which is not only used to offset the pulling force of floor wear-resistant layer and decorative layer on base material layer. So as to avoid warping and deformation of the floor, prevent moisture on the ground from eroding into the floor, and further strengthen the moisture-proof performance of the floor.
Professional article on strengthening the wear resistance grade of floor
National standard: The current national standard GB/T 18 102-2007 divides the mill into two grades, with the domestic first-class requirement of more than 6,000 revolutions and the domestic second-class requirement of more than 4,000 revolutions. It is good to meet these two standards. Many manufacturers come to the market with their mouths open. I switched to the market years ago. At the door of a domestic floor shop, I heard a salesman introduce their home wear-resistant 15000 rpm, Japan f4 star. My forehead is sweating.
European standard: European standard EN 13329 divides laminated flooring into six wear grades: AC 1, AC2 and AC 3. AC4 and AC 5. AC, among which AC 1 and AC 2 are light-duty household products, which are suitable for use in places with mild and moderate resistance in families and cannot meet the second-class requirements of national standards. Therefore, they are all introduced into the China market: AC3 is a heavy domestic and light commercial place, which can meet the second-class domestic standards: AC4≥6000 rpm; AC5≥9000 rpm, AC6 can meet the first-class domestic grinding standard of Chinese national standard, and can be used in places with large traffic such as business people. Everything has two sides. When the wear resistance of the floor is strengthened, the thickening of the surface wear-resistant layer will reduce the true degree of the surface pattern of the floor.
Professional article on strengthening floor slot lock.
The lock is made by milling the lock structure around a single floor with precision mechanized woodworking tools. The machining accuracy of lock and the principle and mode of lock connection affect the stability and strength of the connection between lock floors. Therefore, it is also a very important product quality characteristic of all wood floors, including reinforced composite wood floors. Locks are generally developed by professional patent agencies, and then cooperate with floor manufacturers or authorize them to enter the market. The reinforced floor is a lock floor, and the connection process of each lock is similar. There are also imported 5G lock technologies. , mainly in the short lock, long side is basically the case.
Slotted floor can be divided into two categories: seamless splicing and seam splicing. Seam splicing, V-groove, U-groove. There is no special distinction between good and bad, depending on personal preferences.
Professional articles on strengthening floor thickness
We often see domestic 12MM, imported 7MM, 8MM, 10MM for the thickness of laminate flooring. The thicker the better. Look at the density of the substrate first. Under the same density, the thicker, the more stable. If it is geothermal, too thick will affect heat conduction.
Professional articles on strengthening the environmental protection level of floors
Safety and environmental protection: According to the latest Chinese national standard GB 18580-20 17, laminate flooring is a product directly used indoors. According to the climate box method, the formaldehyde emission limit is 0. 124mg/m3.
The internationally renowned environmental standards for products are as follows
F four-star certification: the highest level of Japanese environmental protection standards, with free formaldehyde emission less than or equal to 0.3 mg/L.
At present, many domestic products claim to meet the F F☆☆☆ standard, which is actually not rigorous, because F4 Star is only authorized by Japanese domestic enterprises or Japanese export enterprises to sell products in the Japanese market. Secondly, F4 Star needs the authorization and certification of Japanese professional testing institutions. Even if it is certified by professional testing institutions in other countries, it may not meet its testing standards. I have a floor imported from Japan here. I know a little about this piece, and I'll talk about it in detail later.
French A+ certification: it is French voc (volatile organic compound), and it is an environmental label for indoor architectural decoration to enter the French market. It is emphasized that the indoor odor, radiation and chemical composition must conform to environmental protection and health after the product is used for a period of time (after 28 days). It tracks the indoor environment data after the product is used.
"IBR" environmental certification: formaldehyde ≤0.006mg/m3=0.00006mg/ L, which is not common in the market.
Finland M 1 Certification: All building materials are divided into three grades according to the amount of harmful substances released: M 1M2M3.
Der Blaue Engel, Germany: "Der Blaue Engel" is the first and earliest environmental protection symbol of products and services in the world, which is specially awarded to products and services that are environmentally friendly in all aspects, ensuring environmental protection and the interests of consumers. Therefore, the environmental protection, durability and durability of raw materials produced and used are all very important comprehensive factors. The corresponding rewards given to Der Blaue Engel are described according to RAL-UZ 76 (wood products) and RAL-UZ38 (wood products) in the wood field.
In a word, these environmental protection signs are ok.
Professional articles on strengthening the brand of flooring
The laminate flooring brand running on the land of China is like the vast starry sky, which appears and disappears every day. There are literally hundreds of unheard-of domestic brands, and imported laminate flooring brands are constantly being updated. It can be said that the so-called top ten brands of laminate flooring are not reliable.
Let's talk about imported laminate flooring brands first. I think the imported laminate flooring should be imported from abroad. With the so-called German technology and design, we should not try to import. It is so boring. Is it good to import laminate flooring? That's not true. I have also seen some imported brands with very high after-sales maintenance. Personally, I think the imported laminate flooring is not the brand, but the product.
To sum up, no matter domestic products or imported products, we don't need to pay too much attention to the brand, but should mainly pay attention to the laminate flooring products themselves.
Strengthen the floor and choose practical professional articles.
How to choose the right one in the vast laminate flooring? For the convenience of everyone, I made up a jingle first.
Don't look at the brand to see the product, look at environmental protection first, the pattern is natural and clear, and the wear resistance level should be kept in mind.
The density of the substrate depends on the thickness, and whether it is seamless depends on preferences. The price is not too expensive.
Whether going to a physical store or online shopping, it is best to have a general color system in mind, which will save a lot of time. Patterns and textures should be natural and clear, and many textures with synchronous wood grains will be better.
Communicate with shop assistants about environmental protection. No, don't be fascinated by various environmental signs. A friend of mine taught me to scald the substrate with 100 degree boiling water and then smell it. I have tried some floor materials myself, which has certain reference significance. Whether it is scientific or not remains to be verified. Don't try when you go to the store.
Be sure to look at the cross section of the floor. Because it depends on the substrate layer, the color of a good substrate layer is uniform natural wood color, without mottled or particles. Pinch it with your nails, or pry open the lock to feel the density.
Regarding the price of laminate flooring, the domestic normal price is between 100 and 200, and the import price is between 100 and 200 and 300, which is almost the same. No matter how expensive it is, it's ridiculous. It is not recommended to choose those that are too cheap, and some of them are made of laminate flooring. They are cheap and mainly used for small projects. The price is between 30 and 60, which is really not suitable for home use.
