采用擋水膠片密封，機械磨邊時水源不外溢，保護機械軸承免受污水銹蝕，提高機械使用壽命。污水不流落地下，營造工廠干凈良好工作環境。

Using water blocking film sealing, the water source does not overflow during mechanical edge grinding, protecting the mechanical bearings from sewage corrosion and improving the service life of the machinery. Sewage does not flow underground, creating a clean and good working environment for the factory.
