When it is implemented, the formaldehyde test device further includes upper cover 14, light-source system 13 is provided with the upper cover 14
With fan 12.
When it is implemented, it is 400~760nm that the light-source system 13, which is wavelength, power is 4 tubulose fluorescent lamps of 8W.
When it is implemented, the upper cover 14 is covered on the quartz cover 7.
When it is implemented, the detecting system 11 is connected with computer.
When it is implemented, it is connected between the silicone tube (3a, 3b) and reaction cabin 8 by pipe connecting piece 6.
The formaldehyde test device concrete operation step of the utility model is as follows：
(1) in thermostatic constant wet chamber, detection model is placed on stent 9, vaseline, lid are coated at the ground of reaction cabin 8
Upper quartz cover 7, is fixed with clip, covers upper cover 14.
(2) coupled reaction cabin and detecting system 11, open the interface between the first silicone tube 3a and injection room 2, and injection is surveyed
Material is tried in injection room 2, connecting interface one closed system of formation.
(3) power supply is opened, starts detecting system 11 and second gas vacuum pump 10b, then is heated injection room 2 with electric furnace 4,
Gas is sent out, after realizing that 8 internal gas circulation of reaction cabin, band injection indoor liquid play completely using gas vacuum, close
Close furnace power.
(4) reaction cabin 8 is carried out with black-out cloth closed, using second gas vacuum pump 10b, realizes that second servo loop gas follows
The gas circulation of loop system, detecting system export the photocatalytic speed curvature V1 of the VOC such as formaldehyde in real time.
(5) light-source system is closed, above-mentioned 1~4 step is repeated, draws half-light reaction rate curve V2.
(6) light-source system is closed, does not put detection model in reaction cabin, repeats 2~4 steps, show that the VOC's such as formaldehyde is dark anti-
Answer Natural Attenuation curve rate curve V3.
(7) according to detection curve V1~V3, after taking the photocatalysis at a certain moment respectively, after dark reaction, first after Natural Attenuation
The concentration of aldehyde, you can calculate the photocatalytic activity of the VOC such as formaldehyde.
