Working principle and related technical parameters of corrosive test chamber

The salt spray test chamber is a kind of test equipment for artificial weather environment "three preventions" (wet heat, salt spray, mold), which is mainly to study the adaptability and reliability of products in machinery, instrumentation, national defense industry and other industries in various environments. What is the operating principle and related parameters of the salt spray test chamber? We can do the neutral salt spray test according to GB/T2423.17 "Testing the Basic Environmental Test Procedures for Electronic and Electrical Products Ka: Salt Spray Test Method". Do the acetate spray test. The relevant technical parameters are as follows:
1. Temperature range: 35-50 ° C / 47-63
2. Temperature fluctuation: ±0.5 °C
3. Temperature uniformity: ± 2 ° C
4. Salt spray settlement: 1-2ml/80cm2·h
5. Spray method: tower spray method (A, B)
A: Continuous salt spray test machine.
B: Programmable salt spray test machine.
The full detection system is used to display the light when the fault occurs.
6. The whole PVC board system adopts advanced three-dimensional reinforcement technology, which has strong structure and never deforms.
7. Adopt automatic/manual watering system, which can automatically/manually replenish the water level when the water level is insufficient. The test is not interrupted.
8. Precision glass nozzle, use 4000 hours to ensure no crystal blockage.
9. Control instruments are all on the same board, easy to operate, and at a glance.
10. With double over-temperature protection, the water level is insufficient to ensure the safety of use.
11. Imported temperature controller, digital display, PID control, high stability platinum temperature probe (error is 0.3)
12. The laboratory uses steam direct heating to increase the temperature and reduce the standby time.
13. The spray tower is equipped with a cone disperser, which has the functions of guiding fog, adjusting the amount of fog and evenly fogging.
14. The pressure tank uses Henry's law to warm and humidify and provide the humidity required by the laboratory.
Saturated barrel NSS.ACSS47±1°C/CASS63±1°C
Laboratory NSS.ACSS35±1°C/CASS50±1°C
The product complies with CNS, ASTM, JIS and ISO standards. The salt spray test is designed to test the corrosion resistance of various materials such as surface coating, electroplating, anodizing, anti-rust oil and other corrosion treatments.
