How to clean the salt spray test chamber

The erosion and destruction rate lies at a considerable level in the oxygen content salt solution on the surface of the experimental specimen and the temperature of the experimental specimen and the temperature and ambient humidity
of its natural environment.

During the experimental period, the sprayer can make the experimental specimen sufficiently moist during the time, and the sprayer should also be stored under the cold and wet standards of the experimental specimen for a period of time and then repeatedly carried out
.

So this kind of experimental method is, in a sense, simulating a natural corrosion-resistant natural environment
.

Experimental specimens are not plugged in the whole process of the sprayer: during the cold and wet storage period, they are generally not plugged
in.

This specification is equivalent to the national standard IEC 68-2-52 (1984) "Experimental Kb: Alternating Salt Spray Test Method"
.

Salt spray test chambers (chambers) must be manufactured
with raw materials that are resistant to corrosion and erosion and do not harm the results of the experiment.

The structure of the salt spray test chamber (chamber) contains the method of causing corrosion resistance should also exceed the following provisions: a.
The standard of the salt spray test chamber (chamber) should exceed the required range
.

b.
The salt spray test chamber (chamber) needs to have sufficient capacity and maintain a homogeneous and stable experimental standard (not harmed by turbulence), and the experimental standard will not be endangered
by putting in the experimental specimen.

c.
Corrosion resistance during the experimental period should not be immediately sprayed onto the
experimental specimen.

d.
The liquid accumulated on the wall of the salt spray test chamber (chamber) or other locations should not be dripped on the
experimental specimen.

e.
In order to avoid the working pressure in the box to rise and maintain corrosion resistance throughout the symmetry, the salt spray test chamber (chamber) should have a moderate discharge hole, and should avoid the discharge hole in the box (chamber) working pressure rise and maintain corrosion resistance throughout the symmetry, salt spray test chamber (chamber) should have a moderate exhaust hole, and should avoid the exhaust hole in the box (chamber) to cause a strong cyclone
.

The humid heat box (room) should consider GB 2423.
3-81 "Electrical and Electronic Commodities Basic Natural Environment Experiment Technical Specifications Experiment Ca: Stable Cold and Humidity Experimental Method" in the machinery and equipment regulations, that is, the air humidity is 40±2 °C
.

The relevant specifications should require the cleaning method of the experimental specimen before the experiment, and should also indicate whether the temporary coating should be removed
.

The cleaning method should not endanger the corrosion resistance to the corrosion effect
of the experimental specimen.

Before the experiment, try to prevent your hands from touching the surface of the experimental specimen
.

Before and (or) after the repair is solved, the appearance inspection of the experimental specimen is carried out, and the electrical and physical properties of the experimental specimen are inspected
according to the relevant standards.
