A SILVER MIRRO FILM FORMING METHOD BE HARMLESS HUMANS USE FOR REDUCING AGENT

摘要

PURPOSE: A silver film formation method using a reducing agent which is harmless to a human body is provided to manufacture an environmentally friendly product by restricting the occurrence of endocrine disrupting chemicals. CONSTITUTION: A bonding layer is formed on a target object(S21). De-ionized water is sprayed to the target object(S22). Ammonia Cal silver nitrate solution and a reducing agent are simultaneously sprayed to an adhesion layer separated from hydrochloric acid(S23). The target object is washed by the de-ionized water after a reducing reaction is completed(S24). Hot-air is provided to the target object for eliminating moisture remaining on the surface of the target object(S25).
