Multi-layer solid wood flooring is a new type of flooring between solid wood flooring and laminate flooring, which is a new trend in floor purchase. The multi-layer solid wood floor retains all the advantages of natural solid wood flooring. It not only has the natural texture and elasticity of solid wood flooring, but also overcomes the common problem of easy expansion and contraction of natural solid wood flooring. It has the characteristics of strengthening the floor against deformation, corrosion and easy cleaning. .
The multi-layer solid wood floor is a splint structure, and its surface layer is made of precious wood and is turned into thin wood for refining. The substrate under the surface layer is made by cutting the ordinary wood into thin slices, making it criss-cross, multi-layer combination, and then using environmentally friendly waterproof glue. The multi-layered sheets are composited by high temperature and high pressure, and the wood fibers are arranged in a network of laminated layers, which are mutually compacted, and the structure is very stable, and the performance is particularly stable, completely overcoming the disadvantage that the natural materials are easily deformed.
The surface of the multi-layer solid wood floor is sprayed with paint several times, so that the paint penetrates into the gaps of the wood tissue, and infrared radiation, electron wires and heat radiation are formed to form a whole in the wood tissue, so that the wood is hardened. Therefore, the multi-layer solid wood floor is not easily polluted, is not easy to be scratched, has a strong wear resistance, and can maintain the beauty of the new material and the texture of the solid wood for a long time.
Due to the multi-layer adhesive compound, the multi-layer solid wood floor has good waterproof performance and can be used on damp floors and areas. Multi-layer solid wood flooring has been treated with insect repellent treatment, and it is environmentally friendly glue, which can effectively prevent pest erosion and is non-toxic to human body.
Practice has proved that the comfort of the foot of the multi-layer solid wood floor is the same as that of the natural solid wood floor, and the paving method is basically the same. The advantages are obvious, and the market consumption is gradually increased.
To choose multi-layer solid wood flooring, we must first select the appearance quality, not only depends on whether the color, texture and paint quality of the surface wood meet the grade standard, but also whether there are decay, dead knots, joint holes, wormholes, skinned resin bags, Wood defects such as cracks or cracks are not strict, the texture of the wood texture and color is harmonious, the paint should be uniform, no bubbles, small white spots, etc., and the surface should not have obvious stain damage. While picking the appearance, you should also see if the tongue and groove around the floor is complete.
Secondly, it is necessary to select whether the size of the product is the same as the size, width and thickness of the product you purchased, and then check whether the dimensional tolerance of the product is consistent with the purchased grade. The method of measurement can be carried out by arbitrarily taking a plurality of floors in the same package and assembling them. After assembling, it is observed whether the joints of the rafts and the grooves are tight, and at the same time, the floor after splicing can be touched by hand, if there is a high and low protrusion feeling phenomenon. , indicating that the product is unqualified. After touching the hand, pick up two pieces of assembled multi-layer solid wood floor and shake it in your hand to see if it is loose.
Finally, picking intrinsic quality is a key indicator of multi-layer solid wood flooring. It can be seen from the water swell thickness expansion rate that its waterproof and moisture-proof performance is as low as possible, preferably less than 2%, and secondly less than 5%. The pyrotechnics are burned on the surface, and if there is no trace, the fire protection coefficient is higher. Formaldehyde content is an indicator that cannot be ignored. According to national regulations, the formaldehyde content per 100g floor should not exceed 9mg. "Three-point floor seven-point installation", so it is recommended to choose a brand floor store when choosing multi-layer solid wood flooring.
