Cabinet 1 inner chamber also is provided with the condenser system 6 that is used for convergent light source, and condenser system 6 is positioned at the top of ultraviolet lamp system 2.
For the ease of regulate detecting required ultraviolet ray intensity, cabinet 1 inner chamber is provided with light intensity regulating system 7, and this light intensity regulating system 7 is at wavelength 190 ~ 420nm, light intensity 0 ~ 50mw/cm
2Adjustable in the scope.
In order to simulate the natural conditions that drench with rain, this detector also is provided with automatically towards the pouring system, this automatically towards the pouring system by elevated tank 8, be located at that sample holds chamber 3 upsides and dashing of being connected with elevated tank 8 drenched device 9, be located at the diversion trench 10 that catchments, the header tank 11 that is connected with the diversion trench 10 that catchments and the conveying water pump 12 that sample holds chamber 3 downsides and constitute.Saving automatically under the situation of pouring system, the utility model can be designed to light, succinct, practical portable fast detecting instrument.
In order to reduce the temperature of whole cabinet, cabinet 1 rear lateral portion is provided with cooling system 13.
For the ease of observing detection time, the front panel of cabinet 1 is provided with time prompting system 14, and this time prompting system 14 is adjustable in 0 ~ 999 minute scope.In addition, also be provided with the window 17 that instrument opens and closes gauge tap 15 and is convenient to working condition in the optical viewer on the front panel of cabinet 1.
For burning voltage, electric current, to prolong the serviceable life of uviol lamp, cabinet 1 inner chamber is provided with constant current constant voltage system 16.
This detector also is furnished with toner and the special-purpose organic contaminant that is specifically designed to the self-cleaning effect of indication.
Using method of the present utility model is as follows:
Sample preparation (existing comparison and detection sample need not this step): get two blocks of grounds that character is identical.
A top layer applies the catalytic self-cleaning product therein, then drips the toner or special-purpose organic contaminant, the oleic acid (detection water wettability) etc. that are specifically designed to the self-cleaning effect of indication of doses, obtains comparing sample A; The top layer of another piece does not apply the catalytic self-cleaning product, but directly drips the toner or special-purpose organic contaminant, the oleic acid (detection water wettability) etc. that are specifically designed to the self-cleaning effect of indication of going up same dose, as comparison sample B.
The sample original state is observed or is detected: by visual inspection or with the original state (color, pollution level, hydrophilic angle etc.) of instrumentation test sample A, B and carry out record.
Then, will compare sample A, B and put into drawer 4, and drawer 4 will be inserted in the cabinet 1, so that comparison sample A, B are positioned at the projection area of ultraviolet light.
Light intensity regulating: regulate required ultraviolet ray intensity by the light intensity regulating system.
Illumination experiment: after the correct placement of comparison sample finishes, set light application time, open instrument and open and close gauge tap.At this moment, UV-lamp is started working, and radiates ultraviolet light, and simultaneously, time display picks up counting and display light shines the time that continues.The illumination duration arrives, and jingle bell prompting is automatically turned off instrument and opened and closed gauge tap, and UV-lamp quits work.
Dash to drench experiment (inspection survey require and decide): open automatically towards the pouring system, simulating natural condition (sunshine, rain and dew etc.) dashes pouring and tests (simple detection does not need this step).
Testing result is observed or is detected: take out comparison sample A, B.Compare by visual inspection or with the final state (color, pollution level, hydrophilic angle etc.) of sample after the instrumentation detection illumination and with original state, wait with the situation of fading, pollution level change degree, hydrophilic angle intensity of variation to characterize self-cleaning effect or the aging quality of base material.Thereby proved that in a short period of time employed catalytic self-cleaning product has the effect of certain self-cleaning effect, hydrophilicity or prolongation digestion time.
Because the light intensity of UV-lamp is much larger than general solar radiation, therefore, the utility model adopts the short irradiation simulation material of UV-lamp to be subjected to the long-time irradiation of sunlight, thereby in the short period of time, by comparison, detect the effect of self-cleaning effect, hydrophilicity or the prolongation digestion time of the catalytic self-cleaning product that uses in the test.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
