2. Working principle
The precision salt spray testing machine realizes the simulation of salt spray environment through the following steps:
1.Salt solution preparation: Mix sodium chloride (NaCl) and distilled water in proportion to form a salt solution.
2.Spray system: Atomize the salt solution through compressed air to form a uniform salt spray.
3.environmental control: Through the heating system and humidity control system, the temperature and humidity in the test chamber are kept constant.
4.test cycle: According to the test standards (such as ASTM B117, ISO 9227, etc.), set the test time and observe the material corrosion.
3. Application fields
Precision salt spray testing machines are widely used in the following fields:
1.Automobile industry: Test the corrosion resistance of automobile parts.
2.Electronic appliances: Evaluate the salt spray resistance of electronic product enclosures and circuit boards.
