What are the standards for the quality of sports wooden floors in gymnasiums?
1. Floor moisture content. In the national standard, the moisture content of sports wood flooring is between 7% and 15.6%, which is a large span and can be met by most manufacturers. Under normal circumstances, the moisture content of guaranteed floor manufacturers can meet the standard, but the environmental humidity of the paving site is too high and improper moisture-proof measures will make the moisture content of the floor exceed the standard. Therefore, reasonable maintenance and good moisture-proof pavement in the later stage are still It is necessary to pay attention.
2. Panel quality. The appearance quality of the sports floor panel is one of the important basis for the floor classification. The national standard classifies the sports wood floor into the first-class, first-class, and qualified products. At present, most of the qualified products are on the market. When purchasing a floor, look at whether the floor surface is uneven, cracked, bug eyes, dead knots and other defects. Generally, there are joints, color differences, and textures on the floor surface, which are all natural properties of wood. In addition, pay attention to the purchase of the color-added version to prevent the manufacturer from filling the color with shoddy.

3. Specifications and dimensions. The sports wooden floor should be horizontal and vertical, and the size should be regular. When purchasing, it can be sampled and assembled to observe whether the gap and the adjacent boards are flat. For floor size deviation, there is no deviation in the national standard requirements, but there is a certain deviation in actual operation. Generally, the allowable deviation is 0.4 mm thickness, 0.3 mm width, and one-thousandth of the length deviation. If the deviation is too large, it is poor. The product even deceives consumers, and consumers can measure and check through on-site sampling and assembly.
