This material is still non-toxic and edible after long-term contact with wine, which shows its environmental performance. Extraordinary.
Note 4: Understand and compare the floor function. Good cork flooring has more than ten natural advantages such as moisture-proof, anti-skid, wear-resistant, anti-static, sound-absorbing, flame-retardant, heat-insulating, soft and elastic, and form the most solid functional system for environmentally friendly and healthy flooring. . At present, the domestic high-grade cork flooring is imported from Portugal, and the high-quality Portuguese WICANDERS cork flooring is the main one. Because it is at the leading level in materials, design and technology, it is also the most comprehensive and stable in terms of functions.
Note 5: First look at the surface sanding surface is not very smooth, there are no bulging particles, cork particles are pure, this is a key part of the selection of cork flooring, involving the material's true and false and quality grade identification, but need Relative professional people go to check.

Generally speaking, the floor is to be installed after the sale, and companies that sell cork flooring will pay attention to this problem.
Note 7: Check the bending strength of the board surface by closing the two diagonal lines of the floor to see if there is a crack on the curved surface. If there is no crack, it is qualified. In addition, you can check the bonding strength and put the small floor into the boiling water, but it is generally difficult to do this.
Note 8: Look at the density. Generally speaking, the density of cork flooring is divided into three levels: 400-450 kg/m3, 450-500 kg/m3, and more than 500 kg/m3. Generally, 400-450 kg/m3 is enough for households. If there is heavy object in the room, it can be slightly higher. If there is no heavy object, the density is small, which has better elasticity, heat preservation and sound absorption.
