Wood floors are the most used materials for homeowners' home renovations and usually account for about 15% of the total amount of renovations. How to choose a floor with guaranteed quality is a concern for many decoration owners. Home improvement supervisors teach you how to choose wood floors.
wooden floor
First, tree species wood floor
There are many types of trees that can produce floorboards. There are precious rosewood and teak wood; in general, there are eucalyptus wood, eucalyptus wood, manchurian ash, and gancrop. There are inexpensive pines and pines, and the price difference is very large. Misleading tree species names on the market are very common. Consumers can check the commonly used wooden flooring business name issued by the China Forest Products Industry Association Flooring Committee, or select their favorite tree species, texture, and color. Select the dyeing board, try to select the stable species of wood to avoid scooping, twisting, bending, cracking, arching and ringing during the long-term use of the wood floor.
Second, choose the size
The solid wood floors currently available on the market are all long and wide in size, such as 900 mm x 90 mm x 18 mm. In fact, the wooden floor should not be short and should not be narrow, should choose less than 600 mm × 75 mm × 18 mm floor, the smaller the size, the stronger the ability to resist deformation. If you like the long, you can use the ground plate, up to 4000 mm, like the wide optional integrated floor, up to 220 mm: the width of the floor should have anti-deformation groove, the groove depth should be more than one third of the floor thickness . If used for floor heating floor, should not be thick, generally 8 mm-12 mm.
Third, choose the moisture content wooden floor
The moisture content is crucial. The moisture content of the purchased floor must be consistent with the local equilibrium moisture content. Buy the floor must determine the moisture content, if the seller does not have moisture meter, do not buy its board. The method of measuring the equilibrium moisture content is very simple. In the exhibition hall, the moisture content of the purchased varieties is first determined, and then the moisture content of the wooden floor of the purchased varieties is checked out. If the moisture content of the two varieties is only 1%-2%, it is a qualified product.
Fourth, the selection processing accuracy
With 10 floors assembled on the ground, hand touch, seeing the accuracy of its processing, finish is smooth, smooth, rake, slot fit, installation gaps, anti-deformation tanks and other assembly is tight.
Fifth, choose the quality of the substrate
Check the level of the floor, whether there are bugs such as insect eyes, cracks, decay, blue changes, dead knots, etc. For small living quarters, color difference can not be too demanding, this is a natural property of wood, as for the natural texture of wood, most of the chord section, a small part of the cut surface, if you want to have the same cut, it is more difficult to achieve in solid wood flooring Unless it is a veneer veneer.
Six, choose paint quality
Dripping paint, roller paint floor, commonly known as paint board. Regardless of whether it is a light or matt lacquer floor, the paint film on the surface of the lacquer board should be uniform, full, clean, blistering, and perforated. Among them, the need to put forward is the degree of wear, it is recommended to buy UV light-curable paint, the market dealer referred to as UV paint board, its wear resistance, scalding and other properties are better than other finishing processes. Burning with a cigarette for 20 seconds does not leave a mark.
The appearance quality of the floor
1. The surface paint is painted glossy, the paint film is full and even, there are no needles, there are no indentations, planing marks.
2. The surface material has no obvious defects. There should be no defects such as decay, dead knots, knot holes, wormholes, cracks, and clips.
3. The perimeter of the slot and the slot are complete.
Product dimensional tolerance
1. Whether the product's size, tolerance, length, width and thickness are the same as the product introduction.
2. Whether the product's size or splicing is tight or smooth. It can be assembled by spot-checking a number of floors on a flat glass table top or floor, looking at its degree of tightness, and determining whether the surface is flat or not.

Floor intrinsic quality
Intrinsic quality is a key indicator of various types of wood flooring, but it is difficult to determine it with a straight feeling, and it must pass inspection methods. Therefore, it is necessary to observe the inspection report. The content is as follows:
Formaldehyde emission
China has stipulated that the concentration of formaldehyde in the air of public places must not exceed 0.12 mg/m3: If, in the laying process, odourous formaldehyde smells have been smelled, the concentration of formaldehyde in the air has exceeded the standard. For the determination of formaldehyde concentration in products, perforated extraction is currently used in China. The obtained "perforation value" indicates the amount of releasable formaldehyde contained in 100 g of the product. If the "perforation value" is about 9 mg / 100 g or less, basically it can meet the national environmental protection formaldehyde concentration standard. If 30mg / 100 g or less, generally meet the B class technical standards.
2. Moisture content
The moisture content is usually about 12% basically qualified (different from area to area, and different moisture content standards are implemented).
3. Gluing performance
When the composite flooring is manufactured, the adhesive coating plate surface is used for hot pressing, so the glue quality directly affects the use effect and the service life. The quality of gluing can be reflected by two performance indicators, namely immersion peeling and gluing strength. The determination of these two indicators is to place the test piece in water with a certain temperature after treatment. The lower the impregnation value, the better. The higher the bond strength, the better.
