The used brine used in the test cannot be reused. Users using a salt spray test chamber can prepare test saline in a ratio of two cups of water plus one bottle of sodium chloride. The salt water is mainly used for corrosion testing of the product. The water level can be added to only three-quarters of the salt water tank, and the average time is about 72 hours.
The test chamber and pressure tank of the salt spray test chamber have automatic and manual water addition functions. The tap water can be used, and the test room and the pressure tank are respectively equipped with low water level indicator lights. When the water level is too low, the indicator light is on and stops working.
Prevent dry burning and damage the salt spray test chamber. The function of adding water in the laboratory is to heat the tank to meet the temperature requirements of the corrosion test. The pressure tank is filled with water to preheat, humidify and filter impurities in the compressed air, so that the test results are more accurate.
The water in the sealing tank is mainly to prevent the salt mist from leaking during the test. On the one hand, it is beneficial to the spray volume and test temperature of the test chamber to meet the salt spray corrosion test standard, and at the same time, it can prevent corrosion effects on peripheral equipment. The test box of Shanghai Huanzheng Test Equipment Factory is developed and produced. At the same time, the product has the characteristics of stable performance, long service life and low failure rate.
What are the standards or requirements for water in the box?
The brine in the brine tank is prepared by using sodium chloride and distilled or deionized water at a concentration of 5%.
