Corrosion is the degradation of metals, the end product of a chemical reaction between a metal surface and the surrounding environmental conditions. The rate or extent of degradation depends on the surrounding gases in contact with the metal. Coatings are applied on metal surfaces to seal the ingress of environmental factors such as moisture or any gas. The coating is expected to withstand a lath-filled environment, which is primarily responsible for corrosion. In order to check the sustainability of the coating material quality control measures are taken.
Salt spray Testers are used to check the quality of such coatings and allow manufacturers to implement the required methods to improve the sustainability of surface coatings. Users can inspect paint products under simulated salt spray accelerated conditions and observe how long the salt spray test can last. For example, if a corrosion test is being done, and a coated metal panel is subjected to 10 cycles in the salt spray test, while another lasts 18 cycles, then it is clear that the coating will take 18 cycles to fail. This is how standards are set and quality is controlled.
The Test Chamber is made of three layers of glass fiber reinforced plastic material. This material is considered lightweight yet provides high insulation for Test Chambers. It ensures that no heat or temperature is lost through the chamber walls during testing. The canopy is designed according to international testing standards and does not allow the saline solution that has settled on the canopy walls to fall onto the samples. Instead it slid off the canopy and slid across the walls of the room. Opening and closing of the canopy is controlled pneumatically for user comfort.
Packed with professional features including HMI based touch screen display, remote control for operation and monitoring, Ethernet connection and much more, the salt spray Tester is undoubtedly a new generation model. Presto has been innovating corrosion testing techniques through salt spray testing. Automatic fogging solutions, storage tanks, network monitoring, alarm notifications via email and more will upgrade your testing experience. It follows several global corrosion testing standards including ASTM B117 and JIS Z 2371. The chamber can be mobile The most distinctive feature of the salt spray collection unit is that it is mounted outside the chamber, which reduces the need to open the chamber without disturbing the test.
