2 Four Kinds Of Judgment Methods Of Salt Fog Test Results

How to Add Water For Salt Spray Test Chamber

Some customers bought a salt spray test chamber, do not know what to use water, how to do?
Salt spray chamber on the water What are the requirements? To understand this, we must first understand the principle and structure of salt spray chamber.

First, the principle of salt spray chamber
It is used to detect hardware, electronic and other surface corrosion resistance of a reliability testing equipment, its main working principle is: the heat pipe to boil water, after a certain pressure to saline solution or acidic solution from the nozzle Spray evenly, spray to the surface of the material, in order to achieve the test result.

Second, salt spray chamber structure
Salt spray chamber on the water What are the requirements? Do test when it is necessary to use water, then what kind of water to achieve the best test results?
Then we have to understand one of its structural features, salt spray chamber filled with water there are two, one is the test box, a pressure barrel. In general, we test the water is mainly to prevent the heat pipe heat when the box burn out, the test can not play a decisive role, we can use our general tap water, pressure water inside the barrel must use pure water, Because tap water there will be a little bit of impurities, easy to plug the nozzle, a nozzle easily rupture, so the pressure inside the barrel must be pure water, but also the use of sodium chloride should choose better not easy to crystallize the salt. Salt crystal is also easy to plug the nozzle.

Third, the specification parameters:
Relative humidity: 85% or more; Saline concentration: 5%; Laboratory capacity: 270L; Salt tank capacity: 25L; Laboratory temperature: 35 ℃ ± 1 ℃ / 50 ℃ ± 1 ℃; Pressure barrel temperature: 47 ℃ ± 1 ℃ / 63 ℃ ± 1 ℃; Spray volume (m1 / 80cm² / h) 1.0 ~ 2.0; Power supply: 220V, 50HZ, 10A
