Salt can reduce metal materials and non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-non-metalian material Metal material performance. Salt corrosion of metal material The mechanism of electrochemical corrosion, rather than the deterioration of metal materials was caused by the comprehensive chemical reactions of salt and material. The corrosion rate depends to a large extent on the amount of oxygen -containing solution, the temperature of the sample, and the temperature and humidity of the environment.
In addition to displaying the corrosion effect, this test can also show the degree of degradation of certain non -metallic materials due to absorbing salt. In the following test method, the time of the spraying salt solution is enough to fully wet the whole piece of sample. Because this kind of wetting is repeated after being stored under damp heat, it is necessary to add to the test standards under the test standard at the atmosphere of the test standard, so it can be able to effectively reproduce the effect of the natural environment.
The salt fog box should be composed of materials that do not affect the effect of salt mist corrosion.
IOS2423.18-2012 The structure of the test box and the method of generating salt and fog can be selected, but the following conditions must be met:
1、试验箱内的条件应维持在规定的范围内；
2、试验箱应具备足够大的容积，能提供稳定的、均一的试验条件，且These conditions are not affected by the sample during the test;
3. The salt mist cannot be sprayed directly on the sample;
4 , Box top, box wall or other parts of liquid droplets cannot be dripped on the sample; 5. The test box should be exhausted well Make salt mist evenly.
The end of the exhaust holeAvoid winds, so as not to generate airflow in the test box.
IOS2423.18-2012 Sprayer Requirements:
The design and structure of the sprayer should be able Essence The material of the manufacturing sprayer should not cause any response to the salt solution.
AOTSI salt fog test box, also known as salt water spray test machine, salt fog test machine, salt fog test box three defense One of the test equipment of salt fog, mold) test equipment is an important advantage of researching machinery, defense industry, light industrial electronics, instrumentation and other industries such as various environmental adaptability and reliability: Good sexThe test time is significantly shortened; a lot of manpower, financial resources, and material resources are saved. salt mist corrosion test
