With the rapid development of modern industrial technology, the application fields of various electrical, electronic and electroplating products are becoming wider and wider, and the environmental conditions they are experiencing are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and selecting the environmental protection measures of the product correctly can the product be safe and reliable during use. Therefore, it is necessary to ensure the high quality of materials or products by artificially simulating environmental tests. The artificial simulation environmental test of the salt spray test chamber is a scientific summary of the actual environmental impact. It has the characteristics of typicalization, standardization, convenient use, and comparison. The diversification of environmental conditions and the importance of environmental testing also put forward stricter requirements for the equipment of the salt spray test chamber. The following is a certain explanation of the test cycle and related items of the salt spray test box.
The test period should be selected according to the relevant standards of the tested material or product. If there is no standard, it can be decided through consultation by the relevant parties. The recommended test period is 2h, 4h, 6h, 8h, 24h, 48h, 72h, 96h, 144h, 168h, 240h, 480h, 720h, 1000h. The spraying shall not be interrupted within the prescribed test period, and the salt spray test box may only be opened when a short observation of the sample is required.
If the end point of the test depends on the time at which corrosion begins, the specimen should be checked frequently. Therefore, these samples cannot be tested together with samples that require a predetermined test period. The samples of the predetermined test period can be visually inspected regularly, but during the inspection process, the tested surface cannot be damaged, and the time and number of unpacking inspections should be as small as possible.
Remove the sample after the test. In order to reduce the shedding of corrosion products, the sample is naturally dried in the room for 0.5 ~ 1h before cleaning, and then gently cleaned with clean flowing water with a temperature not higher than 40 degrees to remove the residual surface of the sample Salt spray solution, and then immediately blow dry with a hair dryer.
