Salt spray test chamber OSH-60

Salt spray test is an environmental test that mainly uses artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. So why do some products need to use salt spray test when testing? What is the role of its testing? Below, the technical engineers of Guangzhou Biaoji will briefly popularize the reasons.

1. In order to verify whether the metal parts on the product will corrode when exposed to the atmosphere or other environments, the product can be placed in the use environment for a long enough time, such as a life cycle of the product. This is time-consuming and laborious. In practice it is rarely used.

2. Salt spray test is an accelerated corrosion resistance evaluation method of artificial atmosphere. It atomizes a certain concentration of salt water, and then sprays it in a closed constant temperature box, and reflects the corrosion resistance of the tested sample by observing the change of the tested sample after being placed in the box for a period of time. It is an accelerated test method, that is, the time is short, not years, only days or even hours.

3. This requires a convenient method to evaluate the corrosion resistance of the product.

The salt spray corrosion test chamber needs to be maintained before it is restarted after it has not been used for a long time:

1. Completely clean the working room and the water seal tank with clean water, and clean the nozzle to prevent the salt from crystallizing and blocking the nozzle;

2. Before re-enabling the imported salt spray corrosion test chamber, conduct necessary inspections on the electrical system;

3. Check whether the pressure regulating valve is within the set range and whether there is water in the saturator and drain it through the drain valve;

4. If the salt spray test chamber is not used for a long time, the water in the saturator should be released;

5. If it is found that the nozzle is blocked by dirt, you can remove the nozzle and clean it with alcohol and xylene 1:1 hydrochloric acid, or use an ultra-fine steel wire to dredge the nozzle, but the surface finish of the inner cavity of the nozzle must not be damaged, so as to prevent the quality of the spray from being affected. . In order to improve the operating efficiency of the imported salt spray corrosion test chamber, the usual maintenance and cleaning work is essential, and starting from some small details will naturally prevent some equipment failures.
