salt fog test purpose: >
Determine the component's ability to resist salt fog corrosion.
The results of the salt mist corrosion test are very direct with other media (including marine atmosphere and seawater) corrosion. However, if the accumulated data of the on -site salt fog test in the laboratory indicates that there is indeed a correlation (such as aluminum alloy), the salt fog test can provide useful data for the use of certain test samples in the sea and coastal areas. Essence The metals used in these samples should be the same or very similar or protective.
Salt Mogo test can be used to assess the quality and uniformity of metal or non -metal protective layers.
The concentration of salt solution: >The salt solution is (5 ± 1)% (Weight percentage) Sodium chloride solution is made of chemical pure sodium chloride in distilled water or deodorized water. The resistance of water used is not less than 500Ω · m.
The pH value of the salt solution: > each prepared salt solution and The pH value should be 6.5 ~ 7.2 when the temperature is (35 ± 2) ° C at the temperature (35 ± 2) ° C. The pH value is measured by acidity meter or precision test strip. The pH value of the salt solution should be adjusted with dilute solution of chemical pure hydrochloride or sodium hydroxide. But pay attention to keep the concentration of salt solution in the specified range.
salt mog set rate: > The corrosion test box
Internal working space is at any point, with a horizontal collection area of 80cm², collecting a solution of 1.0ml ~ 2.0ml per hour (average value of more than 16H). Use at least two collectors: one is near the nozzle, and the other should be as far as possible away from the nozzle. And should be avoided by the test sample, and will not collect condensate droplets from any source. > AOTSI
salt fog test box
also known as salt water spray test machine, salt fog test machine, salt fog test test The box is one of the three defense (three defense (damp heat, salt and fog, mold) test equipment for the artificial climate and environment.An important test equipment of the environmental adaptability and reliability has significant advantages: the corrosion environment can be controlled, the environment is good; the test time is significantly shortened; it saves a lot of manpower, financial resources, and material resources. Electrician and automobiles, aviation, military equipment, hardware tools and other products, components, components, metal materials and products of electroplating, coating, etc. salt fog corrosion test . > Meeting test standards and testing methods:1.ASTM/B117-2011 Salt Mogo Test
