How to add water to the salt spray test chamber

I bought a salt spray test chamber and I don't know what kind of water to use, what should I do? See Xinbao company for you, what are the requirements for water in the salt spray test chamber? To understand this, we must first understand the principle and structure of the salt spray test chamber.

First, the principle of salt spray test chamber

It is a reliability testing instrument used to detect the anti-corrosion performance of hardware, electronics and other materials, and its main working principle is: boiling water through the heating tube, and spraying the salt solution or acidic solution from the nozzle evenly through a certain air pressure, spraying it onto the surface of the material, so as to achieve the effect of testing.

Second, the structure of the salt spray test chamber

What are the water requirements for the salt spray test chamber? When doing the test, we must use water, so what kind of water can be used to achieve the best test effect, then we have to understand its structural characteristics, there are two places where the salt spray test box is filled with water, one is the test box, the other is the pressure barrel, generally speaking, the test water is mainly to prevent the heating tube from burning out the box when it is heated, and it is not decisive for the test, you can use our general tap water, and the water in the pressure bucket must be pure water, because there will be some impurities in the tap water, It is easy to block the nozzle, and the nozzle is easy to rupture it, so pure still water must be used in the pressure barrel, and the sodium chloride used should also be selected from a better salt that is not easy to crystallize. Once the salt crystals, it is also easy to clog the nozzle.
