Detailed configurations as follows:
1, according to CNS JIS ASTM GB2423.19 specifications, can be set constant temperature to control
(A) Salt spray test: NSS, ACSS
1. testing room : 35 ℃ ± 1 ℃
2 saturated air barrels : 47 ℃ ± 1 ℃
(B) anti-corrosion test: CASS (copper acetate)
1.testing room: 50 ℃ ± 1 ℃
2 saturated air barrels: 63 ℃ ± 1 ℃
2, air supply system: air pressure 1Kg/cm2 Two-stage adjustments (coarse / fine-tuning).
(A) the first paragraph for the rough adjustment 2-2.5Kg/cm2, the second paragraph to fine-tune 1Kg/cm2.
(B) Testing configuration is switch connector designed for SO2.
3, spray form:
(A) Using Bo Nute principle to draw brine and then saline spray, atomization uniform, non-blocking and crystallization, so that ensure continuous spraying.
(B) Nozzle: The nozzle is made of special glass, adjust spray volume and spray angle.
(C) spray volume: Adjustable 1 ~ 2ml (80cm2/hr) (average of 16-hour volume).
4, heating devices:
By direct heating, warming up faster and reduction of standby time, when the temperature arrives automatically switch ON / OFF, make temperature accuracy, low power consumption (heating tube is made of titanium alloy).
5, add water systems:
Using automatic water replenishment system, automatic replenishment when the water level is too low.
6, safe protective device:
(A) low water level, automatically cut off power supply.
(B) over-temperature, automatic cut off the power supply.
(C) attached to the safe warning light device.
