3、 Box structure:

1. The box and inner liner are made of PP flame-retardant plastic plate (inner liner made of titanium alloy, outer shell made of SUS304 stainless steel electrostatically sprayed), with a smooth and flat surface, and resistant to aging and corrosion;

2. The box door adopts a tempered glass double door design, with corrosion-resistant silicone sealing rings for better sealing performance, thereby preventing acid mist from leaking out;

3. Embracing air heating, uniform temperature distribution, does not affect acid mist concentration;

4. Baffle type spray does not occupy the space in the box;

5. The top of the test chamber is designed with an obtuse angle structure to ensure that condensed water does not drip onto the specimen;

6. Filtering device: The waste mist discharged from the box enters the filter through the pipeline. The acid mist filtering device designed in the filter, which combines alkali atomization, neutralization, and adsorption, can quickly and effectively filter the residual acid mist in the box and discharge it outdoors after the experiment is completed.

4、 Control system:

1. Adopt a 7.0-inch high-precision color touch screen temperature and humidity control instrument, P.I.D high-precision control, to prevent long-term unstable operation, and set values or programs arbitrarily;

2. Select PT100 testing sensor as the sensor;

3. Control mode: Thermal balance temperature regulation mode;

4. Schneider AC contactors and small relays are used for the execution of electronic components;

5. Gas circuit system: stable and reliable gas circuit components;

5、 Heating system:

1. Adopt titanium alloy high-speed heating electric heating tube;

2. The temperature control output power is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency.

6、 Spray system:

1. spray adopts baffle type spray, guided acid fog, fine fog particles, natural sedimentation, no crystal in nozzle, and adjustable sedimentation amount;

2. The spray gas is subject to two-stage pressure stabilization and regulation, and the oil pollution is filtered and the gas is humidified and preheated at the same time;

3. The atomized solution is stored internally and externally, with a large storage capacity and a preheating function for the solution;

4. Filter elements should be equipped before atomizing the acid solution to prevent nozzle impurities from blocking and terminating the test;

5. All pipelines in the test chamber are made of thickened fluorosilicone rubber pipes, which can be maintained without aging or cracking for ten years;

6.酸溶液具有高低水位指示。

7、 Protection system:

1. Box overheating protection

2. Over temperature protection for air preheating drum

3. Water shortage protection for air preheating bucket

4. End of experiment indication

5. Two stage pressure regulation and protection for compressed gas

6. Leakage protection

8、 Equipment usage conditions:

1. Environmental temperature: 5 ℃ to+30 ℃ (average temperature within 24 hours ≤ 28 ℃)

2. Environmental humidity: ≤ 85% R.H

3. The operating environment requires good indoor ventilation, and no objects should be placed 80 centimeters in front, back, left, right, or right of the machine;

10Acidic atmospheric corrosion test chamberCompliant with standards:
