AIR KNIFE AND PLATING APPARATUS HAVING THE SAME

摘要

PURPOSE: An air knife and a plating device with the same are provided to prevent a passage through which air is sprayed from being blocked by plating substrates even if the droplet plating substances are splattered toward the air knife. CONSTITUTION: An air knife comprises a lib(110), a coating layer(120), and a lip cleaner. The lip forms a passage to spray air and is exposed to the outside. The coating layer is coated on the lip and has lower wettability to a plating substance than to the lip. The plating substance is zinc, and the coating layer is composed of at least one of tin and manganese. The plating substance is in a liquid state. A contact angle between the coating layer and the plating substance is larger than a contact angle between the lip and the plating substance. The lip cleaner cleans the surface of the lip while moving along the lip.
