Once decide the home wants to lay wood floor, want to face 8 options at least next: among them 4 popular options are pure real wood floor, 3 compound, multilayer compound with aggrandizement compound; The big four are bamboo, cork, stone and wood flooring. As for the problem of environmental protection and formaldehyde, pull to see a conclusion finally directly!
01 solid wood flooring
A what about logs
A log can cut out several pieces of blank, a blank can cut out several pieces of floor. The natural attribute that the tree species of log decides a floor, include decorative pattern, colour and lustre, hardness, expand rate, shrinkage. The grades of the billet are the grades of the floor, including the absence of bugs, decay, chromatic aberration and missing edges. And you, need to pass master a few little knowledge, will screen appropriate floor brand and model.
There's no need to agonize over tree species
No.
Just GB/T 15036 listed in the national standard can make wood flooring tree species have 100 kinds. The natural properties of tree species, such as expansion rate, shrinkage rate and hardness, can be optimized during processing. Consumers just choose the patterns and colors they like.
Instead of taking the time to figure out the difference between thousands of tree species such as phan longan, printed eggplant wood and teak (which you can't always figure out if you take the time), find a big brand with guaranteed after-sales service and pick your favorite style to place an order.
C blank grade determines the sense of use
Rain window is leaky, faucet forgets to close, when opening ground to warm, 99% pure real wood floor can rise become warped, arch, craze, be out of shape. Some floor can restore as before, some floor not only cannot go back, still can drop paint even. To explain the mystery, it is necessary to talk about the grading of wood flooring.
To make a jade bracelet, we must first strip the wool from the stone (a whole piece of jade). To make the floor, you also need to cut the blank from the log. The billet has four grades of ABCD, with few insect eyes, no decay, no cracking, even water distribution, perfect as uncut jade. After such billet is processed into the floor, the possibility that produces craze and explode paint is lower, with a few decades basic no problem.
The floor below B class, lack, leak, cracked place is more, want to fill with wood pink and glue. The lower the level, the more places the blank needs to be repaired. Once cracked, warped and deformed, it is difficult to recover.
As a result of "patch" more, such floor can brush brunet lacquer to conceal blemish commonly. So when buying real wood floor, it is best to choose grade A blank, if you cannot be sure, choose the real wood floor that is close to instinctive quality to be able to compare insurance.
03 solid wood floors
Although solid wood is good, but the hardwood resources available on the earth are less and less. Many big country of forest resource are not to be restricted to cut namely ban to cut, bring about wood floor price to compare a year tall one year. In order to improve the utilization rate of resources, the composite flooring with hardwood "skin" + non-hardwood "core" mode came into being.
3 layer solid wood are on the market most "close" the compound floor board of solid wood, why? It has a layer of hardwood on the top and fast-growing wood in the middle and bottom. It looks very close to natural materials and USES very little glue.
However, the fast growth wood used in the middle of three layers of solid wood density is low, strong water absorption, air humidity changes, the floor is easy to deformation, stepping on it will have a crunching sound.
On the left, there are three layers of solid wood. The middle layer, which is white and thick, is fast-growing wood
Additional, the fast growing lumber among is thick and soft, the hardwood mu PI of surface layer must add a few thicker, ability lets a floor more classics trample. Usually 14mm thick three layers of solid wood, with 3mm thick veneer. Nevertheless, skin of surface layer wood is thicker, the risk of craze is bigger, after sale also is more troublesome.
The three layers of solid wood veneer just processed in the factory have been cracked and deformed, and need to be repaired in the later processing
Overall, the stability of 3 solid wood is inferior than other compound floor board one drop drop, but it USES glue quantity little, price is cheaper than real wood floor, advantage still is apparent.
03 layers of solid wood
Why develop multiple layers of solid wood when you have three? Because the veneer of 3 layer solid wood wants 3mm thick, multilayer solid wood wants 1-2mm thick only, resource utilization rate is higher.
The top one is multi-layer solid wood, the bottom one is three-layer solid wood, look at the thickness of the skin gap to know
Multiple layers of solid wood surface is hardwood, middle and bottom structure similar to plywood, by several pieces of wood in a horizontal and vertical staggered way pressed together, so that the deformation can offset each other's stress, greatly reducing the possibility of floor deformation, cracking.
The top is hardwood, and the middle and bottom are multi-layer hardwood floors. If you cut a hardwood floor into pieces and lay them on top of layers of hardwood, you may be able to lay 10 layers of the same size
04 laminate flooring
Aggrandizement is compound floor surface wear-resisting layer (3 oxidation 2 aluminium) with wood grain paper (3 get together melamine paper), in the middle is high density board, namely wood becomes pink, add adhesive, the man-made board that makes through high temperature high pressure again. Wear-resisting layer is responsible for anti-smashing and anti-scratching, wood paper is responsible for imperfection, high density board is responsible for stability.
Frankly, there can be a lot of problems if the manufacturers don't do their research and control properly. It is formaldehyde to release a quantity above all, aggrandizement compound originally glue is much, if manufacturer wants to cut corners with difference glue, formaldehyde does not know to exceed bid how many times.
The second is the repetition rate and surface technology. Want to achieve the effect that passes for the real, must raise the imitability of wood grain paper, when producing even enough steel plate, can press every floor to give the fluctuation that corresponds with decorative pattern and sunken. However, when you go to large and small floor factories, you will find that most factories have no requirements for beauty, can complete the task. So the aggrandizement on market ability has so much ugly compound floor board.
To meet the requirements of both the United States and environmental protection, we need to be either a major European or American exporter or a domestic manufacturer that takes the middle and high-end route. When everybody chooses aggrandizement compound floor board, can pay attention to 3 main points: a look has E1 class inspection report; Second, to see the degree of simulation of wood grain paper; Third, brand history and scale. If you think all three of these conditions are OK, you can start!
