1, than the color: by observing the floor at the mouth of the substrate color, you can identify the quality of the substrate substrate quality. High-quality flooring substrate color should show the natural pine, poplar color; inferior flooring substrate due to the production process did not use high-quality logs and use Zamu, shrubs; or in order to reduce costs without veneer, so poor quality The color of the material will show dark brown, after comparison will be able to clearly see.
2, look at the fiber: by observing the substrate cutting at the substrate wood fiber, you can identify the quality of the substrate substrate quality. High-quality flooring substrate cutting can be seen evenly, stout, arranged dense wood fiber, fiber color showed natural wood color; poor quality substrate cutting wood fiber showed a significant uneven thickness, and even significant Of the sheet-like objects, fiber color is different, there are dark, light-colored, and even can see dark brown spots.
3, smell the smell: by smell the smell of the substrate substrate interface can also identify the quality of the substrate substrate quality, good floor exudes a fresh woody flavor, not pungent, not dazzling; poor floor fragrance is too rich, pungent, Even the situation of tears.
4, check the cross-section: from the edge of the internal substrate, high-density laminate flooring looks very detailed. Good to strengthen the floor substrate feels very smooth, plain, no grainy, poor feel very rough, cut the wood floor, the good distribution of the cross section of the floor is very uniform, do not see a clear distribution.
