VOC Test Chamber

The process of testing pollutant release in an environmental chamber can be summarized as follows: placing materials and products or their samples in a test chamber and adjusting environmental conditions such as temperature, relative humidity, and air displacement rate in the chamber as needed; Sampling at the exhaust port or inside the environmental chamber; Appropriate methods were used to analyze gas samples to identify major pollutants and their concentrations over time. The release rate and release characteristics of the material and product are then determined based on the measured concentration.

1. Test role:

The process of testing pollutant release in an environmental chamber can be summarized as follows: placing materials and products or their samples in the test chamber and adjusting environmental conditions such as temperature, relative humidity, and air displacement rate in the chamber as needed; Sampling at the exhaust port or inside the environmental chamber; Appropriate methods were used to analyze gas samples to identify major pollutants and their concentrations over time. The release rate and release characteristics of the material and product are then determined based on the measured concentration.

2. Performance characteristics

1. The whole machine integrates 1 cubic meter and 225L environmental chamber specifications, which can meet the test requirements of 1 cubic meter and environmental chamber at the same time.

2. Heat exchanger process: high heat exchange efficiency and small temperature gradient.

3. Cold and hot anti-temperature control water tank: stable temperature control.

4. Imported humidity temperature and humidity sensor: the sensor has high accuracy and stable performance.

5. Refrigerator: imported freezer, stable operation and long service life.

6. Protection device: The climate box and dew point water tank have high and low temperature alarm protection measures and high and low water level alarms

7. Protective measures; The compressor also has overheat, overcurrent, and overpressure protection measures, and the whole machine operates safely and reliably.

8. Stainless steel inner box: the inner cavity of the thermostatic box is made of mirror stainless steel, the surface is smooth and non-condensing, and does not adsorb formaldehyde to ensure the detection accuracy;

9. The thermostatic box is made of hard foam material, and the door is made of silicone rubber sealing strip, which has thermal insulation and sealing performance. The box is equipped with a forced air circulation device (forming a circulating air flow) to ensure that the temperature and humidity in the box are balanced and consistent.

10. The equipment adopts the international jacketed structure, which is compact, clean, efficient and energy-saving

3. Structural principle:

1. Inner box material: 304 mirror stainless steel plate seamless welding, polished and around the welded place, no deformation, the inner wall is flat and smooth, the color is uniform, there is no exposed bottom, layering, bubbling, scratches, all edges and corners are arcuated, easy to wash and clean with water.

2. Outer box material: A3 color steel plate electrostatic spraying, the coating layer is flat and smooth, the color is uniform, there are no defects such as exposed bottom, layering, bubbling, spots, deep scratches and other defects, the cabin and door are effectively thermally insulated, polyurethane and mineral wool double-layer sandwich insulation, the thickness of the insulation layer is not less than 60mm, the thermal conductivity is not greater than 0.01W/(m•K), and the lap between the inner wall plates is seamlessly welded.

3. Air exchange device: A device that can continuously control the air exchange rate (dry air flow meter, or other electronic air flow metering device) is installed inside the cabin. The air inlet and outlet should be on different inner walls and at different heights to ensure that the air flow into the cabin meets the corresponding standard requirements.

4. Air circulation (mixing) device: a fan is installed in the cabin to strengthen the air mixing in the cabin; The air flow rate near the surface of the specimen is between 0.1m/s and 0.3m/s (adjustable).

5. Background concentration in the box: The background concentration of TVOC is less than 20 μg/m3, and the background concentration of any single target volatile organic compound (VOC) is less than 2 μg/m3.

4. Clean gas supply system:

1. Compressed air: air volume: 2 m3/h;

2. Dryer: Handle large air volume: 2m3/h;

3. Special clean gas filter: including high-efficiency particle filter and activated carbon adsorption VOC filter, treatment large air volume: 2 m3/h, after treatment, TVOC concentration <0.02mg/m3, any kind of VOC< 0.002mg/m3, particulate concentration greater than 0.5um < 100/m3, formaldehyde content <0.006mg/m3
