| titleOfInvention | A kind of environmental protection tap and preparation method thereof |
| abstract | The present invention relates to manufacture and field of surface treatment, environmental protection tap being specifically related to the precipitation of a kind of heavy metal free and preparation method thereof, including following procedure of processing: step (1), gone out metal faucet by gravitational casting, obtained the metal faucet of high finish surface by physics polishing；Step (2), carry out physical vapour deposition (PVD) nitride, make the outer surface of metal faucet form nitridation diaphragm；Step (3), carry out the halides of chemical gaseous phase coated with parylene or Parylene, make the inner and outer surfaces of metal faucet form organic film.Metal faucet is gone out by gravitational casting, high finish surface is obtained by physics polishing, carry out physical vapour deposition (PVD), then carry out chemical gaseous phase deposition, utilize the excellent permeability that chemical gaseous phase deposits, surfaces externally and internally at tap deposited one layer of organic film, this layer of organic film plays isolation shielding action, makes water not contact with metal, thus obtains the metal faucet that heavy metal free separates out, the preparation method of the present invention is simple, and production cost is low. |
