The working principle of the salt spray test chamber

Application Field:
The salt spray test machine is also called the salt spray test chamber, the full name is the salt spray test chamber, which is mainly used to test the corrosion resistance of the samples. At present, it is widely used in the aerospace industry, automotive electronics, electronics and electrical, mobile phone digital, plastic products, metal materials and other industries to test its corrosion resistance. It also simulates the extreme conditions under natural conditions or working conditions to understand the samples to perform temperature conditions.

Standard:
It meets the following standards: IEC60068-2-11 (GB/T2423.17), GB/T10125, GB/T1771, ISO9227, ASTM-B117, GB/T2423-18, QBT3826, QBT3827, IEC 60068-2-52, ASTM-B368, MIL-STD-202, EIA-364-26, GJB150, DIN50021-75, ISO3768, ISO 9227, 3769, 3770; CNS 3627, 3885, 4159, 7669 etc.

Working principle of the salt spray test chamber:
The working principle of the salt spray test chamber is relatively simple, mainly compressing the corrosive solution into an air spray, spraying the sample, and wrapping the spray on all sides of the sample as much as possible. This test can be performed continuously or cyclically until the sample is corroded. , And then record the corrosion time as the corrosion resistance of the sample. The longer the time, the better the corrosion resistance of the sample.

Generally, the corrosion solution in the salt spray test chamber is mainly 5% sodium chloride solution or 0.26 grams of copper chloride per liter added to the sodium chloride solution as the salt spray corrosion solution. In addition, the salt spray test chamber can independently control the sedimentation volume and spray volume of the salt spray to ensure constant test temperature, convenient operation and stable test environment. Therefore, it is often used to test the corrosion resistance of daily necessities or industrial products.

The test chamber can reach any temperature point from room temperature to 50℃ in the test working space, and keep it constant. Conduct salt spray corrosion tests on materials or products in a cabinet with a specified volume under constant temperature and relative humidity. The material used to manufacture this equipment is imported corrosion-resistant PVC plastic sheet, which does not react with salt-containing solutions or acidic salt-containing solutions, and does not affect the test results. In the design of this equipment, the internal and external pressures are balanced, and the salt spray can settle freely in the box and can be adjusted to the range specified by the national standard.
