1, Color: wood core material and sapwood transition part of wood material, floor surface by using color or special coloring treatment, eliminate the color difference between the sapwood and core material, as a high-quality solid wood flooring sales to deceive consumers. Because the core material and sapwood air dry density, moisture content, wood hardness is not the same. Easy to cause the floor arch, deformation, cracking and other series of quality problems.
Identification method: floor surface polished with sandpaper or sawed floor look after the end will be showing the color is very serious.
2, Transfer board: some tailings line board and the floor plate of different length by the finger joint splicing process and acts as a pure solid wood flooring sales to deceive consumers. Because of this kind of floor use adhesive joint, formaldehyde content is not environmentally friendly, and because the floor stress were not easy to cause deformation and cracking.
Identification method: longitudinal sawing or grinding visible finger trace.
3, Tiemianban: in the wood substrate inferior on 0.05mm 2mm thickness of wood veneer, as a pure solid wood flooring sales to deceive consumers. Because of this kind of floor from the substrate due to inferior quality is not stable, and will use the inferior wood veneer and pressed together with adhesive, easy to cause the peeling veneer and the substrate, and there a formaldehyde content is not environmentally friendly.
Identification method: surface can be recognized by the observation of the surface and the bottom floor, wood floor surface and ground grain is consistent, and the panel is completely different.
4, Transfer board: spotted in such as wormholes, cracks and other defects of timber, as solid wood flooring sales to deceive consumers. The transfer board is inferior B class wood substrate, the floor quality is not stable, wood is not natural, like floor, at the same time, because the paint coating process and lead to less paint easy to fall off, cracking.
Identification method: can be recognized by the surface of wood, wood floors wood natural, wood surface of the transfer plate are the same, basically no color, back and front of the wood is completely different.
5, The short-lived board: wood floor is a kind of high technology, has a certain technical content of modern industrial products, some enterprises due to their own conditions, in the paint adhesion, surface hardness and so on to reach the national standard, especially the moisture control is not strict, resulting in the floor pavement in a very short period of time in the paint off, there will be deformation, surface scratch phenomenon.
