Rust Preventatives: Influence of novel engineered desiccant on corrosion levels seen in transcontinental packaging systems

摘要

The control of relative humidity by the use of traditional desiccants such as calcium chloride, silica gel, clay etc., is limited by the saturation point of the material and the effects of cyclic drying at higher temperatures and re-absorption of vapor closer to the saturated state. While packaging can be designed to keep as much moisture out as possible, the use of an improved desiccant can be a vital tool to control the corrosion effects of existing moisture in a closed atmosphere. Using extensive testing methods which simulate the cyclic nature of temperatures and humidity that are involved in transcontinental shipping, it was shown that the use of this novel engineered desiccant drastically decreases the level of corrosion present in the closed system by dramatically increased levels of absorption. It is expected therefore that the use of this product in place of conventional desiccants will lead to far greater efficacy in combating corrosion and will be much easier to use with properly-engineered, conventional shipment packaging without resorting to the use of expensive and specialist packaging.
