Salt spray test chamber spray and compressed air principle

Salt spray test chamber for artificial service air martial natural environment "three prevention" (cold and humidity, corrosion resistance, aflatoxin) experimental equipment of high, is scientific research machinery and equipment, national defense science and technology, light industry electronic devices, instrument panels and other manufacturing industries a variety of natural environment adaptability and credibility of this key experimental equipment. Artificial service to speed up the simulation of corrosion-resistant natural environment experiment is the use of such experimental equipment with the necessary capacity indoor space - salt spray test chamber, in the capacity indoor space with artificial service, resulting in corrosion-resistant natural environment to the commodity corrosion-resistant corrosion resistance can quality to carry out embrittlement. Contrast with the natural natural environment, corrosion-resistant natural environment of fluoride salt concentration is usually natural natural environment corrosion-resistant water content of several times or several times, so that the rate of leaching corrosion further increase, the salt spray test on the commodity to carry out, calculate the results of the time is also greatly shortened.

The basic principle of salt spray test chamber sprayer: each salt spray test chamber are required to have a collection area of 80CM, adjust the total number of sprayer in the enterprise time, so that the corrosion resistance room can show the average value of the concentration value of corrosion resistance, to facilitate the collection of each collection vessel collection, collection time of at least 16h, 1.5 ± 0.5ml per clock, the detection time is less than 16 clock, the time to measure the average value of at least 8h.

 

Salt spray test chamber air compression principle.

 

The air pressure is 0.7 to 1.4 bar and is not contaminated with soil, oil or other air pollutants, which are separated by the application of vegetable oil and grease in a concrete separator or a porcelain working pressure filter, the remaining air pollutants in the air compression do not exceed 0.2 mg per cubic metre, the oil and dust particles are below 5 μm and are maintained with double distilled water and neat air compression by introducing a gas humidifier. The ambient humidity of the gas is maintained at a temperature of 33-37°C for SS and ASS and 50±2°C for CASS. The water is sufficiently mixed in the air compression to avoid an increase in the concentration of the salt solution due to the concentration of NaCl during the whole process.
