What are the testing standards for sports wood floors?
Sports wooden floor is a special floor for indoor basketball gymnasium. It has good sports performance and good safety performance. It is more complex than household wooden floor and has high quality inspection standards. What are the inspection standards?
1. Measurement of formaldehyde emission: choose large-mouth bottles with good airtightness, saw several alternative brand models of the same size, and put different bottles. After 24 hours of sealing, open the bottles and smell them one by one, and you will compare which brand of flooring emits less formaldehyde. If you are afraid of inaccuracy, two people can smell it one by one to be more sure.
2. Surface wear resistance: Use 180 sandpaper (thickness of sandpaper, no problem), the same person, with the same force and method, rub back and forth on the same ground, 50 times. Without the tri-alumina floor, the wood grain paper is likely to be severely damaged. The surface of the wear-resistant paper is 46 grams, and the surface has no serious scratches; the wear-resistant paper is 38 grams or more, and the surface will be worn to varying degrees.
3. Swelling rate of water absorption thickness: saw and cut the replacement model of similar size, put it into boiling water after numbering, 5-8 minutes. Take it out and compare the swelling of its edges. It is best to measure the thickness of the model measuring point with a micrometer in advance and make a mark. After soaking in boiling water, take out the thickness measurement, and calculate the expansion rate of the thickness after soaking in boiling water.

4. Floor geometry: This comparison test needs to be compared with the whole board. a) Put the two floors together, and feel the height difference of the seam with your hands; you can also consciously feel and compare the model room of the floor. The difference between brands should be obvious. b) Secondly, look at the tightness of the splicing gap. If the floor has side bends, the gap will not be very tight. This reflects the processing precision of the floor.
The impact formed by the sports wooden floor during the exercise will cause vibration to the wooden floor plane, so the sports wooden floor must have a good shock absorption function, and its protection function should also take into account that one person cannot affect the adjacent when moving the wooden floor. people.
