Gymnasium staff always pay attention to the maintenance of panels when cleaning sports wooden floors, but ignore the cleaning of expansion joints, knowing that expansion joints are easy to become a breeding ground for harmful microorganisms, and it is also the key to affecting the service life of sports wooden floors.
Investigators conducted investigations in Beijing and Shanghai. In three-year solid wood floor samples, the minimum clearance was 0.9mm and the maximum clearance was over 6mm. The average number of bacteria per square centimeter of the floor is 4.56 grams of crevice waste is 7 times the minimum standard for hospital infection departments and wards.
The following contaminants are major crevices in sports wood floors.
1. Mold. Mold can multiply rapidly in warm and humid environments, and some can cause nausea, vomiting, abdominal pain, etc., and in severe cases can cause respiratory and intestinal diseases, such as asthma and dysentery.
2. Dust mites. When the number of dust mites in indoor air reaches 500/g, dust mites are one of the main culprits of allergic diseases and can cause acute asthma.

3. Biologically active substances. Provide good living conditions for bacterial reproduction, such as dandruff, hair, saliva, etc.
4. Particulate matter can be inhaled. By inhaling infectious diseases, bacteria can attach to particles floating in the air.
If the construction personnel do not operate properly, there may be a large amount of garbage under the floor, which will cause more serious harm. In order to prevent gaps in the sports wooden floor and hide dirt, it is necessary to install it carefully first, and strive to block the pollution from the source. In the process of using the sports wood floor, pay attention to the cleaning of the expansion joints to prevent the accumulation of dirt. If the accumulated dirt cannot be sucked out, or the corners are not easy to clean, you can use a small brush dipped in floor cleaner to scrub, or you can directly pour it on a rag to wipe.
