摘要： PURPOSE:To prevent atmospheric corrosion by controlling the relative humidity of the atmosphere in contact with the surface of a stainless steel product at the limit humidity for generation of the atmospheric corrosion intrinsic to the deposit on said product or below. CONSTITUTION:A temp. and humidity sensor 17 is disposed in an air duct and the temp. and humidity are continuously measured. The measured values are fed to a control panel 18. When the increase of the humidity to the limit humidity for generating atmospheric corrosion or above is detected by the panel 18, a refrigerator 19 is started to cool further the cooling water fed through a cooling water inlet 9 and is fed to a cooling coil 8. The high-humidity air fed from a fan 7 is cooled on the surface of the coil 8 and the steam in the air in this stage is liquefied down to the satd. steam pressure corresponding to the surface temp. of the coil 8 and is discharged as drain through a drain port 20. The atmosphere humidity is thus maintained at the limit humidity for generating corrosion or below.

摘要： PURPOSE:To decrease easily and efficiently the waste material to be decontaminated at a low temp. by bringing an electrolyte film into contact with the metallic surface to be decontaminated, bringing an electrode into contact with the surface of the electrolyte film and passing electric current between the metallic surface and the electrode. CONSTITUTION:An electrolyte film 2 is brought into contact with the place to be decontaminated of a metallic material 1 to be decontaminated. The film 2 consists of a high polymer material or gel mixed with a complexing agent or electrolyte, or a high polymer material which itself is an electrolyte. A metallic electrode 3 is brought into contact with the surface of such film 2 and electricity is conducted via an ammeter 5 to said electrode so as to make the material 1 positive pole and the electrode 3 negative pole. The base metallic material is then dissolved and the eluted metallic ion is captured by the complexing agent in the film 2. If the direction of the current is reversed, the oxide on the surface of the metallic material is dissolved and the eluted metallic ion is captured and fixed by the complexing agent.
