◆◆◆◆◆◆◆◆ ◆ Strengthening the common sense of floor purchase ◆◆◆◆◆◆ ◆ Just a brief introduction, there are still many things to pay attention to.
the scientific name of laminate flooring is "impregnated paper laminated wood flooring". Generally speaking, it is composed of four layers of materials, namely, wear-resistant layer, decorative layer, high-density substrate layer and balanced (moisture-proof) layer.
specifications: the specifications of laminate flooring are generally expressed in this way-length * width * thickness. These three degrees are all measured in millimeters, which are measured in smaller units in the actual production process and require higher accuracy. BBL
The common lengths in the domestic market are around 12 and 13, and some short boards are around 6 to 8 mm.. The width is 19mm, and some narrow plates are about 13mm and 17. The thickness is usually 7 mm, 8 mm and 12 mm.
Home decoration is generally paved with 12mm, which is relatively thick and has a good foot feeling. 7, 8 mm are generally low-grade shops, rental houses or hotels.
The thin plate has good heat transfer, so it can generally be used on geothermal, but attention should be paid to the formaldehyde index when choosing, and heating will increase the formaldehyde volatilization.
It's better to choose a floor with smaller specifications for a small room, so that less material is consumed; The large slab is suitable for the living room pavement with relatively large area.
colors: it is said that there are thousands of them, giving customers more choices. Generally, the numbers of colors are represented by letters, numbers or a combination of the two. Such as JM127, etc.
the choice of color depends on the purchase at home, the color of walls and homes, and personal preferences, so that the overall effect will be good-looking.
Generally, the lighting in the home is better. If the windows face south, you can use matte or matte floors. Colors can be neutral or darker. What is popular in the market now is the red floor, which is light red to deep red. The color of this floor is not too light, and it is more stable with furniture.
base material: the base material is the most important part of laminate flooring, which is made of wood fiber, glue and some additives. An important reason why BBL
laminate flooring is cheap and environmentally friendly is that it doesn't require a whole piece of wood like solid wood, but as long as it is made of wood, it can be processed, like branches, and solid wood can't be used. In the future, large-scale natural wood will gradually decrease, so the utilization rate of wood will be very high. Therefore, in the future, laminate flooring will be a kind of flooring that is very beneficial to the environment and should be advocated in a sustainable development society. BBL
When buying a floor, carefully check the color of the base material and whether there are impurities. BBL
Generally, a good substrate is very white, without impurities and very dense. Inferior substrates are generally yellow, black and mixed with millimeter-grade wood fibers, which can be seen by the naked eye. Also, please don't confuse the wax sealing board with the inferior base material. The floor with wax sealing is dark from the outside, so it's best to scrape off the wax around the spot to see the color of the base material. BBL
but there are some special cases, some substrates are not very white in color, but the texture is very good. Mainly depends on the density of wood, whether there are impurities, and whether the wood fiber particles are big or not.
the green core board has good water resistance. Green core means that waterproof substance is added to the base material, and green pigment is added to distinguish it from the general base material. A test method with good water resistance is to put the floors made of different materials into the water, and leave a section on the water. After a while, we will see to which height the water stains on that section on the water. The higher the waterlogging height, the worse the waterproof property of the substrate; The lower the waterlogging height, the higher the water resistance of the substrate.
surface embossment: there are also many embossments, generally including embossed surface (small, medium and large), crystal surface, small pitted surface, bark pitted surface, mirror surface, high-gloss surface, real wood grain and so on. Silk-faced boards are very high-grade in the market. Generally, the best configuration will be selected, such as Bell's Fugui series, the top-grade washable sub-base material, the highest standard household wear-resistant cushion of more than 6 rpm, and the top-grade cork mute pad. The technical requirements of synchronous true wood grain (that is, the embossing on the surface is like the texture of a tree) are also very high. At present, the die plate with the smallest tree grain spacing in China is in Bell floor, so only in Bell can narrow plates with true wood grain be seen.
one function of surface embossing is beautification, and another greater function is anti-slip, which is better than ceramic tile.
buckle type: there are round buckle and Valinge buckle. Of course, there are many buttons. Generally, smart locks are available on the market, which are easy to install and disassemble. Moreover, there is no need for glue and nails during installation, and the floor is very tightly connected.
Chamfering and rolling paint: a processing technology, which cuts off some of the upper edge of the floor at an angle of 3 or 45, and then paints it to cover the color of the base material, making the edge color more layered and similar to the solid wood floor, so it is deeply liked by consumers. After the chamfered and painted boards are paved, there is a very shallow crack between the boards, which is easy to accumulate dust and inconvenient to clean. Moreover, after long-term use, some paint will fall off. Therefore, it is best to seal the joints with wax after paving, and then seal them once in a while.
there is no such problem for boards that are not chamfered.
die pressing plate: a notable feature of the die pressing plate is that the upper edge of the plate has a downward arc depression, and the two plates are closely combined after being spliced, but there is a small groove, which is called U-shaped die pressing in the industry and also V-shaped die pressing. This kind of board is reinforced floor in most cases. A great advantage of the die pressing plate is that it is easy to clean, and the dust in the small ditch is very convenient to clean up, as long as a rag or mop is wiped.
there is another kind of molding called V-shaped molding, which looks the same as chamfering paint rolling, but V-shaped molding is to press the decorative layer and wear-resistant layer together at an angle of 3 degrees or 45 degrees.
Molding is the patent of Dewei flooring.
mute: add cork cushions or other cushions similar to cork on the back of the floor. After using the cork floor mat, the noise of trampling on the floor can be reduced by more than 2 decibels (quoted from the cork floor mat factory), which has the effects of increasing the sense of feet, 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.
Waterproof: Some manufacturers, like Bell Flooring, will provide samples to customers who are interested in buying, and let them soak with boards of other brands for one day to test the product quality. There will also be wax sealing or waterproof materials around the board. When you buy a floor, try to choose a floor that is surrounded by wax. Such a board is waterproof, moth-proof and formaldehyde-proof, and it will also effectively reduce the noise and wear between boards.
Wear-resistant revolutions: The wear resistance of laminate flooring mainly depends on the aluminum oxide content in the surface layer, and a certain wear-resistant revolution corresponds to a certain aluminum oxide content. For household floors, wear-resistant revolutions are usually more than 6 revolutions (45 grams of wear-resistant paper), while in public places, wear-resistant revolutions are usually more than 9 revolutions (commercial standard). The number of grinding revolutions basically determines the service life of a strengthened floor. Generally, the wear resistance can be guaranteed for 2 years at 6 rpm when the substrate is large and sub-grade. However, the higher the wear resistance, the better. Too high wear resistance will make the wear-resistant layer brittle and not resistant to folding and bumping. BBL
formaldehyde emission: E standard ≤.5mg/L, E1 ≤ 1.5mg/L. Generally, the better products are E grade. The safety value stipulated by the state is E1, E is a very high standard, and the enterprises that can really reach this standard are very powerful. Only the laminate flooring certified by E1 level is called green building materials.
finally, there is an impact resistance. This is something we usually ignore. Generally, if there are children at home or if they are not careful, they will sometimes drop heavy objects on the ground and sometimes leave a small pit on the floor. The reinforced floor of high-density board is very impact-resistant, and the pits will be very small. After the smooth floor is smashed, the pits will be slightly more obvious. It is recommended to buy that kind of non-smooth floor, such as a small embossed floor, which can be scraped with a knife.
