Alternating salt spray corrosion test chamber

Alternating salt spray corrosion test chamberSalt spray corrosion is used to test the reliability of the corrosion resistance of the tested samples. Salt spray refers to a dispersion system composed of tiny salt droplets in the atmosphere, which is one of the three prevention series in artificial environments. Many enterprise products need to simulate the destructive effects of the climate around the ocean on the products, so the salt spray test chamber should be operated. The salt spray test is divided into two types: neutral salt spray and acidic salt spray. The difference lies in the standards and testing methods they comply with, namely the "NSS" and "CASS" tests, which are common testing methods in artificial weather conditions.

Working Principle:

1. The Bernoulli principle absorbs salt water and atomizes it uniformly, blocking the phenomenon of crystallization, ensuring continuous testing. Compressed air is wetted through the bubble tower on its way to the nozzle, and the nozzle atomizes the corrosive solution and air into a corrosive mist. The heater inside the box maintains the temperature inside the box.

2. Spray mode:

a、 Bernoulli's principle involves absorbing salt water and then atomizing it uniformly to prevent crystallization, ensuring continuous testing.

b、 The nozzle is made of tempered glass, which can adjust the size of spray volume and spray angle. The precision crystal glass nozzle can guarantee no crystal blockage for 10000 hours.

c、 The spray amount is 1~2ml/h adjustable.
