Example : The Advantages of VS-PACK
Precondition of the estimate
Size of Package : 1000x1000x1000 (mm)
Storage period : 120days
Package Specification : Aluminum barrier bag (humidity permeation degree 0.1g/㎡）
Delivery condition ：Export (passing Equator)
ESTIMATION : Conventional Method
| Method １ Adopting Silica-gel, Cray (desiccant) The amount of the necessary desiccant : 250-350g Anticorrosion mechanism : To eliminate humidity (maintaining humidity below 50%RH) | Method ２ Adopting anticorrosion inhibitor Using volatile corrosion inhibitor Anticorrosion mechanism : To protect the surface of the metal product from oxigen cotact by a corrosion preventive thin layer. |
Risk:
At The shipment by large size packaging ,sometimes unanticipated humidity flows into the package.
In Case Desiccant humidity absorption capacity may be saturateｄ and It will be a reason of dew concentration occurrence.
In Case Corrosion preventive thin layer would be peeled off from the surface of metal by repeatedly occurrence of dew concentration
ESTIMATION : Adopting VS-PACK
Required Numbers of VS-PACK : Only 2pcs of 60g/ pack
1. Initial anticorrosion function :
Desiccant eliminates humidity from inside the package before corrosion preventive thin layer would be made
2. Secondry anticorrosion function ：
Corrosion preventive thin layer covers on metal surface.
3. Maintaining anticorrosional atmosphere ：
Desiccant maintains appropriate humidity level to prevent occurrence of dew concentration.
Instruction and directions for use
• Barrier package is necessary
• VS-PACK should be placed upward of package. In case more than 2pcs of VS-PACK is used in the package, each VS-PACKs should be placed as far as possible.
Other anticorrosion products
