Sichuan walk-in walk-in salt spray chamber in Sichuan salt spray chamber Equipment Co., Ltd. Wuhan still testing experience. Structural features: ▲ corrosive salt spray chamber the entire PVC board system, the internal use of state-of-the-art three-dimensional reinforcement technology, strong solid structure, never deformation; ▲ automatic / manual water system, the water level is low, automatic / manual supplement water level the functional test does not interrupt; the tower spray ▲ spray system, with no crystalline nozzle and filter system equipped with a salt solution, the settlement amount of freedom to adjust the salt spray evenly distributed; ▲ control instruments are on the same board, the operator simple and clear; ▲ attached double over-temperature protection, water shortage alert, to ensure that the use of safety; ▲ laboratory using direct steam heating or temperature faster, shorten standby time; ▲ lid and the box is water sealed way, does not produce the aversion precipitated phenomenon, effectively prevent corrosion of the laboratory; Sichuan walk-in environmental chambers Control Center: ▲ corrosive salt spray chamber high-precision PID temperature control device, the error is ± 0.1 ℃, Fuji, RKC Honeywell table (optional). ▲ still measured salt fog spray nozzle, a high-precision glass products, can use 4000 hours to ensure that no crystallization obstruction. ▲ All circuits are equipped with circuit breakers, heater with electronic and mechanical overheat protection device. Multiple safety systems, to make the operation safer. ▲ salt solution filter by: pipette at the assembly water quality filter (prevent nozzle clogging terminate test). ▲ temperature sensor with the stainless steel PT100Ω platinum resistance, the use of high precision, long life. ▲ salt spray chamber test chamber yet measured using direct steam heating, shorten standby time, warming fast, uniform distribution. ▲ wholly independent heating systems, electric heating heaters titanium alloy. Effective protection of the water level control system of the wet bulb life of the heater to prevent air burning. Corrosive salt spray chamber test mode: ▲ NSS test (neutral salt spray test) using a 5% aqueous solution of sodium chloride salt solution PH value is adjusted in the neutral range (6 to 7) used as a spray solution. Were taken to 35 ° C test temperature, to requirements the salt spray sedimentation rate between 1 ~ 2ml/80cm2.h. ▲ ASS test (acetic acid salt spray test) 5% sodium chloride solution was added glacial acetic acid, the PH value of the solution was reduced to about 3, the solution becomes acidic, the final form of the salt from neutral salt spray becomes acidic. Its corrosion rate than the NSS test about three times faster. ▲ CASS test (copper accelerated acetic acid salt spray test) is a newly developed abroad a fast salt spray corrosion test, test temperature of 50 ° C, adding a small amount of copper salt - copper chloride salt solution is strongly induced corrosion. Its corrosion rate is about eight times the NSS test professional Sichuan into the salt spray chamber Manufacturer: Wuhan still testing experience Equipment Co., Ltd. is a walk-in environmental chambers, walk-in test chamber, walk-in constant temperature and humidity box, walk-in environmental chambers, walk-in artificial climate chamber
