Corrosionbox improves comparison with outdoor results
Worldwide, materials used by manufacturing industry are exposed to natural or industrial corrosion in shape of salt fog, humidity, smoke and vehicle exhaust. Laboratory corrosion tests are used extensively for selection of materials and their surface protection. Corrosionbox chambers are what you need to predict corrosion resistance of materials such as paints and coatings.
Salt spray test
A corrosive solution is turned into a vapour mist through a nozzle located in the centre of the chamber. A fog diffusing tower distributes the fog over the entire test zone. The compressed air required for fog production is heated and saturated with moisture in a pressurized humidifier before it reaches the nozzle. One or more heating elements, depending on chamber capacity, ensure uniform temperature in the test chamber.
Exhaust solution collected in the bottom of test chamber is drained away through a drain to the floor.
Salt spray test can be executed with all chamber models.
Condensation water test
Test chamber bottom is filled with demineralised water. Water is heated and evaporates condensing on the surface of samples.
Chamber temperature is 40 °C. Continuous condensation test can be executed with all chamber models.
Cyclic corrosion test
A large number of cyclic corrosion tests are made possible by combining salt spray environment with condensation humidity and air drying . Cyclic corrosion testing has become increasingly necessary in recent years. Dry Corrosion is one of the most popular cyclic tests alternating salt spray and air drying.
Cyclic tests can be executed with all enhanced model chambers. Depending on cycle-type some options have to be installed during chamber manufacturing.
