Salt spray corrosion test chamber manufacturers salt spray corrosion test chamber can be used to assess the material and its protective layer of salt spray corrosion resistance, and similar protective layer of the process quality comparison, but also parts, electronic components, metal materials, electrical , Electronic and other products of the protective layer and industrial products, salt spray corrosion test. Today, salt spray corrosion test chamber manufacturers to teach you all seven tips:
1, first of all we have to know what is neutral salt spray test: neutral salt spray test is the earliest application of the most widely used in an accelerated corrosion test method. It uses 5% sodium chloride solution, the pH value of the solution in the neutral range as a spray solution. The test temperature is 35 ℃, requiring salt fog sedimentation rate of 1 ~ 2ml / 2000px2.h between. To do a neutral salt spray test, we first need a device to promote the spray, that is, our salt spray test must be an external device - air compressor. Its function is to compress the air, the air into the salt spray test machine, for the spray test manufacturing gas source.
2, salt spray corrosion test chamber connected to the air compressor, but also pay attention to a detail problem, that is, the introduction of the box gas source, we can see there is a device called oil and water separator, the device from what role it. The original air, there are oil and gas, water vapor, dust and other impurities, air compressors can not separate these impurities, and if these impurities directly into the salt spray test chamber spray device - nozzle, over time, the nozzle may be blocked, so Will affect the accuracy of salt spray test, so the oil and water separator comes in handy, through the device air impurities will be it automatically filter out to protect the nozzle.
3, then, salt spray test machine connected to the power supply, then its operation panel indicator light will have three lights will be bright, respectively, two low water level lights, a low salt water indicator, which is told that the salt spray test machine has three The local water level is insufficient, we need to add water to test, first of all, we first add pressure inside the pressure tank, until the pressure tank low water level lights so far.
4, need to add salt water inside the test machine inside the pure water, open the lid, add pure water to the inside until another low water level lights so far. There is also a need to join the saline place, we need to first configure the salt water, generally do neutral salt spray test 5000ml pure water by adding 500g sodium chloride, and then stir evenly, open the reagent inlet to add salt water.
5, then we open the operation panel on the operation of the switch, then the laboratory temperature indicator light, pressure bucket temperature indicator light, here because of neutral salt spray test, the two parameters set to 35 ℃ and 47 ℃.
6, and then start to set the relevant parameters of the spray, according to their own test material standards, in the programming timer set salt spray test chamber spray interval, and then set the total test time. After the test time is set, open the timer switch, salt spray test machine set the time to set up.
7, and finally open the salt spray test machine on the operation panel of the spray switch, salt spray test machine can start spraying test. After the salt spray test is completed, the deodorizing switch is opened and the sealed salt mist gas in the body of the salt spray test can be automatically removed to avoid corrosion of the interior.
