The board is exposed to neutral salt fog, and the results of salt fog exposure are evaluated by the principles or standards of the relevant parties.
The device is a salt fog test box, which should include the following components.
Equipment requirements:
salt fog test box , should be salt tolerance to salt resistance Water solution The material of liquid corrosion is made or in the lining, and it should be carried with a cover that can prevent the drop of condensate water from falling into the test board. To ensure that the spray is evenly distributed, the volume of the box should not be less than 0.4m3. 
The size and shape of the salt fog box should make the amount of solution collected by the spray collector (6.4) within the limit of 10.2.
The salt fog box with a volume greater than 2m3 is to facilitate the operation of the design and structure.
2. The temperature control component should be controlled by the constant temperature element in the box, so that the components in the salt fog box should be kept within the specified temperature range. This component should be at least 100 mm from the wall of the box. The thermometer should be placed in the box as a whole.
3. The spray device should be composed of a nozzle made of a nozzle of a compressed air supply, a storage tank of a spray solution, and one or more materials made of salt -resistant materials. The compressed air supplying spray should be removed by the filter to remove the oil and solid particles, and the pressure should be kept at (70 ~ 170) KPA. The air should be humidified by the saturated tower column of the water filled with water before entering the nozzle. Filling water should be at least in line with the third -level water specified by the IOS 6682, and its temperature is a few degrees Celsius than the salt fog box. The temperature of the water depends on the air pressure and type of nozzle. Regulating the air pressure makes the recycling speed in the box and the concentration of the collected solution is kept within the specified range.

salt fog test box The test machine and salt fog test box are one of the three defense (damp heat, salt fog, mold) test equipment in the artificial climate and environment. An important test equipment has significant advantages: the corrosion environment can be controlled, the environment is good; the test time is significantly shortened; it saves a lot of manpower, financial resources, and material resources. Equipment, hardware workerElectro -plating, coating, etc. of products, components, metal materials and products, etc. salt mist corrosion test .
