The aim of the project is to determine the effectiveness of the VCI (volatile corrosion inhibitor) papers under sudden variations of temperature and relative humidity and under extreme corrosion atmospheres. Another objective is the evaluation of the necessity of the use of VCI papers according to the characteristics of furniture and its transport operations duration.
There has been an increment of the named “sensitive transport” that is the one that put both packaging and products on a test due to its special characteristics – atmospheric extreme conditions, high level of vibration, shock risks, etc. – and requires an extra packaging resistance.
If the products transported have metallic elements then the risk of corrosion is high (maritime transport is one of the critical ones but it is not the unique) that can
Taking into account that it is impossible to change the transport conditions, some products have been developed to prevent corrosion phenomena. The most popular are the VCI papers that claim to be “ecological” being fully recyclable and exempted of hazardous chemicals for health. Their employment also avoids the presence of protective oil or grease and their use is simple as well.
But some questions arise on their mode of employment related to:
Effectiveness: if the degree of protection is the same for all metals, alloys and welding.
Durability: if VCI papers are prepared to resists long transport cycles
Use conditions: if the degree of protection remains the same under extreme atmosphere conditions like the ones that occur in maritime transport.
Necessity: if they must be always employed as a prevention action against risky atmosphere conditions incrementing the packaging prize or if on contrary they must be used only when the transport characteristics made their employment unavoidable
The project gives answers to all those questions carrying out a research on several commercial VCI papers, protecting different types of metals, alloys and welding under extreme atmosphere conditions.
