摩擦系数低、便于加工 Low friction factor, easy to processing
在金属刀片中比较柔韧，摩擦系数低，清污效果好，不易伤缸辊。
It is a flexible blade and has a small friction coefficient, thus it will not damage the cylinder roller easily. Besides, it produces good cleaning effect.
优点：有较好的韧性， 宝石头部摩擦系数低，具有超长的使用寿命。
Advantages: good toughness, low friction coefficient of the ruby head, long life.
你既没有防滑护垫也没有不干胶贴纸导致浴缸表层静摩擦系数低，因此摔倒也不足为奇。
Not surprising. You have no safety mat or adhesive stickers to allow for purchase on surface with a low coefficient of static friction.
