Coating material photocatalytic purification performance test chamber
1. Product introduction:
The coating material photocatalytic environmental chamber is used to test the purification performance of coating materials, purification products, and photocatalytic materials. In addition, it can also test the purification efficiency and purification durability of formaldehyde, toluene, VOC and other pollutants in the material. , in line with the testing requirements of standards JC/T 1074-2021 "Purification Performance of Indoor Air Purification Function Coating Materials", JC/T 2177-2021 "Diatom Mud Decorative Wall Materials" and other standards.

Mirror stainless steel |
|
The doors and flanges at both ends are pressed and sealed with two pressing handwheels. |
|
|
Test chamber positive pressure control |
|
|
Air sampling system |
The test hatch is equipped with air sampling channel holes, 2 sets. |
|
Stirring fan |
Located on the top of the test cabin, it has three blades with a radius of 7~10cm, and the rotation speed is adjustable ≧5r/s. |
|
LED light |
Power 16W, color temperature 6500W, 1 white light |
|
UV lamp |
Power 20W, wavelength 365nm |
|
Pass box |
300*300mm |
|
Contaminant placement box (optional) |
Your company provides the pollutant generator. If we are worried about product leakage, our company can install a storage box above the machine for storage. |
|
The gas generator |
The gas pump flow rate is 3L/min~4 L/min, the vaporization temperature is 50℃~60℃, and the gas generating chamber volume should be less than 200 cm* |
|
Under an overpressure of 1000 Pa, the gas leakage rate is less than 0.5% of the box volume per minute; under use conditions, the gas leakage rate is less than the supply air flow 1%. |

Two 1 cubic meter environmental chambers. The inner wall dimensions of the test chamber are 1250 mm × 800 mm × 1000 mm. One is the sample chamber where the test sample is placed, and the other is the comparison chamber where the blank glass plate is placed. The joints of the chambers are Sealing glue treatment, the gas extraction port is the center point of the side wall of the environmental chamber.
A 30W fluorescent lamp is placed at the top center of the environmental chamber for testing photocatalytic materials that require light. A 15 W fan is placed at the center of the left side of the test chamber for uniform air in the chamber. Four stainless steel sample racks (the outer diameter of the steel pipe is 5 mm) are placed in the length direction of the test cabin to place the sample plates, and the sample plates are 300 mm from the bulkhead, and the distance between the sample plates and the bottom of the cabin is 300 mm.
4. Test principle:
The photocatalytic air purification material sample is placed in a reactor containing pollution markers, and its performance in purifying air under the action of light is obtained by measuring the removal of markers.
