Corrosion test room is used to simulate corrosion test in artificial environment. It is used to check the comparative quality of metal materials with or without corrosion protection. Walk in type corrosion test room suitable for fast analysis of corrosion resistance of discontinuous holes and damage in organic and inorganic coatings. Furthermore, for quality control purposes, comparisons can be made between samples coated with the same coating. The salt spray test is particularly suitable for detecting discontinuities such as holes and other defects in organic anodizing and conversion coatings of certain metals

● Neutral Salt Spray Test (NSS): Suitable for metal and its alloys, metal coatings (anode and cathode), conversion coatings, anodized coatings, organic coatings on metal materials.︱Acetate Spray Test (AASS): Suitable for testing copper + nickel + chromium, or nickel + chromium decorative coating; It was also found to be suitable for testing anodic coating of aluminum.

● Copper Accelerated Acetate Spray Test (CASS): The copper accelerated acetic acid salt spray test is a fast salt spray corrosion test, the test temperature is 50℃, add a small amount of copper salt to the salt solution of copper chloride, strongly induce corrosion and its corrosion rate is about 8 times that of NSS test. In the process of salt spray test, the recovery of salt spray must be done to prevent salt spray from removing corrosion laboratory, especially high-strength corrosion liquid in CASS test.

Salt Fog System︱Pneumatic spray mode, air pressure regulation for two levels of pressure regulation: one is the intake pressure, the general adjustment is 0.2~0.3MPa. The second level is spray pressure. In order to meet the requirements of the latest standard GB/ t10125-2012 spray pressure (precision 2kpa), the equipment USES customized high precision pressure gauge.

The spray method is to use an internal glass nozzle placed in a circular plastic tube, the spray is guided by a tower tube, and then dispersed to the laboratory by a cone type disperser. The brine before spraying is injected into the spray tower through the brine storage tank bucket.

No crystallized nozzle is adopted, atomized by baffle, the fog diffuses evenly and settles freely in the height of the tower of the atomizer in the test box, which can be adjusted and guide the salt fog, with fine fog particles and natural settling. Special quartz glass nozzle, no salt crystal. The spray gas first goes through the oil-water separator to filter and regulate the oil and water pressure, then enters the saturated cylinder for preheating and humidification, and then reaches the nozzle through the solenoid valve and pressure regulating valve.

The salt water tank has built-in hidden type and large storage capacity. The salt water is filtered by sand core filter before atomization to avoid debris blocking the nozzle. Two standard fog-collecting funnels are placed in the test room and connected to the measuring cylinder outside the box through pipes to monitor the settlement at any time.

Ambient Temperature: 5℃ ~ +28℃; Environmental humidity: ≤85%; Good ventilation (preferably in a separate room, well ventilated or with exhaust fan, 1 meter away from sewage exhaust)
Requirements for Air Source: Pressure greater than 0.4 Mpa, rated displacement greater than 0.3 m3/ min, equipment with 8 mm fast connector.
Water Source: There is tap water nearby to add and rinse water inside the equipment, and there is distilled water or deionized water ︱Power requirements: 3 meters of power cord.
Environmental Requirement

As there are many factors affecting the corrosion process, such as the formation of protective film varies greatly with the different conditions encountered, there is little direct relationship between the resistance to salt spray and the resistance to other media. Therefore, The obtained test results cannot be used as a direct guide to the corrosion resistance of the tested metal materials in all available environments. Similarly, The performance of different materials in tests cannot be a direct guide to the corrosion resistance of these materials in use.
