The solid wood floors currently on the market mainly include teak, beech, ash, birch, and high-grade imported timber.
Solid wood flooring generally has two models, one is a long strip of wood flooring, the length is generally between 45cm ~ 90cm, the thickness of more than 1.6cm, the width of more than 6cm, it is not directly bonded to the ground, the following must play keel Or a large core board for the layer; the other is a short ultra-thin type, it is directly bonded to the ground, and its quality requirements are mainly high degree of dryness, low sleepiness.
Some details of the process of laying solid wood flooring need to pay attention: one, the size of keel wood can not be too thick, otherwise it will affect the space utilization, the general thickness of 4 × 1.5 ~ 2cm can; Second, can not use cement nails, but should use After electric drill, use wood wedges and screws to drill about 2.5cm into the ground. 3. After the keel mallet is installed, it will not move around. Therefore, there is no need to use cement mortar to fix around, so that the floor will not be damaged due to lack of maintenance time. Arch or tile-like deformation; Fourth, for home installation, foam pad, 9mm plywood can not be used, if you want to use, should use 12cm ~ 18cm plywood, and to be divided into 4 to 6 blocks, drilling well keel , board surface around the nails. Due to the different quality specifications of solid wood floors currently on the market, the most obvious ones are of different lengths. Therefore, it is recommended that when purchasing solid wood floors, the length should not exceed 60cm and the width should not exceed 7.5cm. Although long, it is easy to assemble, but it is prone to warp and warp, and it is easy to deform. However, a short solid wood floor is not easy to warp. In addition, it is easy to grasp the gaps between boards and the fight.
The qualified standards for the installation of solid wood flooring are: firm paving, no emptying, cracking, skew, warping, plastic spill, dirt, etc.; board-to-board joints to deal with the straight seam, tight seams, seam width should be about 1mm The skirting board is tightly connected to the floor, and it should be close to the wall and seamless. Another point to note is that the number of solid wood floors to be purchased should be slightly higher than the actual paved area. Generally 20 m2 of room is expected to have 1 m2 of additional material to be used as a backup. In addition, whoever buys the floor of the house who asks to lay, this can be guaranteed for one year, if the quality problem appears, it is easier to solve.
How to identify composite wood flooring
Solid wood composite wood floor is a new type of wood between solid wood flooring and laminate flooring. It has the natural texture, texture and elasticity of solid wood flooring, and it also has the advantages of strengthening the floor's anti-denaturation and easy cleaning. Solid wood composite flooring is made of wood cut into thin slices, criss-cross, multi-layer combination of bonding, so that the wood fibers involved in each other to maintain stable.
To choose solid wood flooring, we must first select the quality of appearance, not only depends on whether the surface layer of wood color, texture and paint quality meet the grading standards, generally should not have decay, dead knot, knot hole, wormhole, resin jacket skin, cracks or Weak joints and other wood defects, wood texture and color perception harmony, paint should be uniform, no bubbles, small white spots and other phenomena, the surface should not have obvious stains and damage. While selecting the appearance, you should also see if there are defects in the tongue and tongue around the floor.
Secondly, choose whether the size of the product is the same as the length, width, and thickness of your purchase, and then check whether the dimensional tolerance of the product is the same as the grade you purchased. Measurement method: You can take multiple pieces of flooring in the same box to assemble yourself, and check whether the combination of rakes and grooves is tight after assembling. At the same time, you can touch the spliced ​​floor again after the hand is touched. If the height is more prominent, feel better. The phenomenon indicates that the product is not qualified. After touching it, pick up two pieces of multi-layer solid wood flooring and shake it in your hands to see if it is loose. In short, no loosening can occur.
Finally, select the intrinsic quality, which is a key indicator of composite wood flooring. From the water absorption thickness expansion rate can be seen that its waterproof, moisture-proof performance, the lower the better, preferably less than 2%, followed by less than 5%. Fireworks are burned on the surface and if there are no traces, the fire resistance is higher. Formaldehyde content is an indicator that cannot be ignored. According to the national regulations, the formaldehyde content of every 100 grams of floor shall not exceed 9 milligrams.
In addition, the experts also pointed out that consumers must carefully inquire about the difference between different grades of composite flooring when purchasing laminate flooring, and remember the code of the selected grade product, and check whether the code on the packaging is consistent after delivery.
The key to choosing a laminate flooring
Reinforced composite wood flooring is generally composed of four layers of composite materials, namely wear layer, decorative layer, substrate layer and bottom layer.
The bottom layer is the moisture-proof layer, generally made of polyester material, which can block the moisture and moisture from the ground, thereby protecting the floor from the wetness of the ground and playing a balance with the above layers.
The base material layer is the main part of the reinforced composite wood flooring. Most laminate floorings use the density board as the base material, because the density board has many advantages that the original wood does not have, such as the dense and uniform structure of the density board, the average particle distribution, etc. . The density of the MDF is mainly distinguished by its density value.
The decorative layer is also the pattern layer, above the substrate layer. This layer is made of a specially processed paper. Due to the heated reaction of the tri-hydrogenated ammonia solution, the chemical properties are stable, and it becomes a beautiful and durable surface paper. It has an abrasion resistance of 400 rpm, and is waterproof and UV-resistant without fading.
The wear-resistant layer is a layer of anti-wear agent that is evenly pressed on the surface of the laminate floor. It has surprising wear resistance.
Many consumers are most concerned about the coefficient of wear when purchasing reinforced wood flooring, and consider wear resistance to be the most important. In fact, this is a misunderstanding because the wear coefficient is not exactly proportional to the wear resistance. The wear coefficient is mainly determined by the density of Al2O3. The distribution of Al2O3 on the floor surface is too dense, the floor will be brittle, and the flexibility will be weakened. This not only affects the service life of the floor, but also affects the transparency of the floor surface. Gloss. According to European standards, the wear-resistance coefficient of general household laminate wood flooring is sufficient for more than 4,500 rpm, and our country's reinforced composite wood flooring has reached this standard. This reminds people from another perspective that the use of reinforced wood flooring does not equate to durability. Therefore, experts suggest that the selection of reinforced wood flooring starts with the selection of convex grooves.
Reinforced wood floor is divided into two kinds: flat mouth and high mouth. At present, there are many products on the market. The two sides of the floor are respectively cut into convex and concave shapes on the two sides of the floor. When the floor is installed, the convex groove wedges together, which not only facilitates installation but also prevents the floor from being deformed.
The floor of the company's mouth looks like a simple pavement. In fact, there is a great deal of knowledge in this area. Poorly mastered or inconvenient will affect the service life of the floor. First of all, select the floor carefully to see whether the convex groove grinding is regular, fine and uniform, and whether the protruding portion of the convex groove and the concave portion of the groove are of sufficient length. In general, a slightly longer bite will be stronger. Secondly, it depends on whether the convex groove bite is tight, and some floor convex grooves are not precisely die-cut. The protruding groove groove is loose and wide. This kind of floor installation is very easy. It does not show any problems after installation, but it leaves a hidden danger in the future. After the floor is stressed, the convex groove flutters in the groove, which quickly causes the glue to peel off. At the interface of the floor, it forms a gap that is not easily visible to the naked eye. This is a taboo for installing the laminate flooring, and is also an important basis for the classification of the floor.
From the seam's floor, water, moisture, and dust emanate from the gap, causing the floor to expand, deform, and warp. In order to fill the seams, many construction workers look for a road at the time of installation—using more glue, which in turn helps. Because the floor is subject to thermal expansion, contraction and compression and expansion, the glue is used more and more to lose the expansion space between the floors. The floor will instead crack and debond, which will affect the service life. The correct method of installation should be to apply glue only on the floor of the floor groove. No glue can be applied under the groove and under the groove to prevent the floor from expanding and cracking. In order to reduce the amount of glue, and to avoid cracks from the floor surface, the floor itself is required. The quality is good, and the convex groove bites tightly, which is the reason why the convex groove of the floor is repeatedly emphasized.
Warm room floor budding
The use of the greenhouse floor originally started from Japan and South Korea. Both Japanese and Koreans have used the wall-warming heating habits, and gradually expanded the warm-up space to the entire floor space. The unique ambiguity culture has led to many uses of the solid wood flooring, and the greenhouse floor is one of them.
The greenhouse floor is actually a derivative product of a multi-layer engineered wood floor. It is produced by peeling the wood into several millimeters thick veneers and crisscrossing the wooden veneers with different fiber orientations. The base material of the solid wood composite floor is affixed with rare hardwood chips that have undergone special treatment on the surface; after the rivers and top coats have been sprayed, the production of multi-layer solid wood composite flooring has been completed. After such a production process, the physical properties of the warped and deformed deformation caused by the temperature change of the wood are fully improved, and at the same time, the natural properties of the wood, such as air permeability, elasticity, sound insulation and heat preservation, are maintained. In order to adapt to the use of high temperature, it is required that the greenhouse floor should be thick, heat-dissipating, and crack-proof. Moreover, the volatilization of harmful gases cannot exceed the standard. Therefore, the greenhouse floor materials must use environmentally friendly substrates in order to meet the requirements. It can be seen that the production process of the greenhouse floor has its particularity. So, is it possible to use a heated floor in a room without floor heating? The answer is yes, and in the absence of high temperatures, the floor will be more stable when used.
There are three types of materials available in the currently listed greenhouse floor: beech, oak, and cherry. The dimensions of the greenhouse floor are 90 x 150 x 8.5 mm; the same as the reinforced floor, it is also easy to install and maintain. It can be installed in two ways: one is the floating paving method, and the first step is to lay the moisture-proof pad on the concrete floor with the concave/convex depth of less than 5mm, and then glue the bottom of the hothouse floor with the moisture-proof pad. Generally, four dots are coated. You can. After aligning the mouth firmly, it can be used after the glue is cured for 12 hours; this is the most convenient and simple installation method. Another method is to lay a layer of nine PCT boards or other composite boards after the wooden keel has been leveled on the ground. The bottom of the floor of the heating room is glued and then installed on the top. After 12 hours of glue curing, it can be used after installation. The gap should not exceed 1 mm. The greenhouse floor has been painted before leaving the factory, so no paint is needed for use. Maintenance does not require special waxing maintenance. However, the wooden products are more fragile, so as to avoid scratching the surface with hard objects, so as to avoid damage to the surface paint film.
Wait for the northern region. Due to the advanced production technology, bamboo flooring can adapt to the northern climate.
Bamboo flooring and solid wood flooring, the most afraid of is the damp. If it is soaked with water, it will deform. However, because the fiber density of bamboo flooring is much higher than that of wood flooring, when the bamboo flooring and wood flooring are simultaneously immersed in water for 24 hours, the expansion rate of bamboo flooring is only half that of wood flooring, and even lower. Consumers in the North can use it with confidence.
