Why Rubber Soles Prevent Slipping on Wet Floors
为什么橡胶鞋底能防止在湿地上打滑
-
Rubber soles have a bumpy texture that grips floor surfaces well.橡胶鞋底表面凹凸不平，能很好地抓牢地面。
-
They create more friction than smooth soles on wet tiles or wood.相比光滑鞋底，橡胶鞋底在湿瓷砖或木地板上产生的摩擦力更大。
-
Rubber also sticks slightly to water films due to molecular attraction.橡胶还能因分子间吸引力轻微吸附水膜。
-
Wet floors reduce grip, but rubber fights this with flexibility.湿滑地面会降低抓地力，但橡胶凭借柔韧性对抗这一问题。
-
Shoes with deep grooves channel water away from contact points.带有深纹沟槽的鞋子能将水从接触点导走。
-
This keeps the sole touching the floor firmly.从而让鞋底牢牢贴住地面。
-
Rubber bends easily to match small bumps on any surface.橡胶易于弯曲，可贴合任何地面的微小起伏。
-
That’s why rain boots and gym shoes use rubber soles.因此雨靴和运动鞋都采用橡胶鞋底。
