Testing result be illustrated.
Object of experiment：Haze liquid sample is tested to the protection effect of haze, specifically using the protection effect to PM2.5 as
Index.
Laboratory sample：PWM1, FWM2, FWM3, FWM4 (correspond respectively to the particulate matter provided in Examples 1 to 4 barrier material
Material)
Experimental Establishment：PM2.5 detectors one (U.S. TSI, Dust Trak DRX 8533)
Non-woven fabrics gauze mask, active carbon mask, each 1 of anti-particulate matter mask；
Artificial clip area is 80cm2Non-woven fabrics gauze mask segment 4, active carbon mask segment 4, anti-particulate matter mask
Segment 4；
Experimental principle：Sampled point air is tested using PM2.5 testers, measures PM2.5 values, after measure different mouths
PM2.5 values after cover and spraying different experiments sample, use formula：
PM2.5 values before filter efficiency=(PM2.5 values after PM2.5 values-filter before filter)/filter,
The filter efficiency to PM2.5 can be calculated.
Experimental method：
One, mask measure of merit
1, PM2.5 detectors are opened, instrument maximum flow rate 1.5L/min is adjusted to, carries out calibration zero.
2, PM2.5 measuring heads are replaced, test sample point air PM2.5 values are read after stable reading (about 5 minutes)
PM2.5 numerical value, record.
3, non-woven fabrics gauze mask is wrapped into PM2.5 measuring heads with rubber band, simulation wears mask effect, then starts to adopt
Sample reads PM2.5 numerical value, record after stable reading (about 5 minutes).
4, above-mentioned 2-3 steps are repeated, measure successively using before and after active carbon mask, using anti-particulate matter mask before and after
PM2.5 values simultaneously record.
5, it is calculated, in unused haze nebulised sample, non-woven fabrics gauze mask, active carbon mask, anti-particle
Filter efficiency of the object mask to sampled point PM2.5.
Two, haze sample test
1, haze sample F WM1, FWM2, FWM3, FWM4 are prepared.
2, allow PM2.5 measuring heads exposed in air, test sample point air PM2.5 values, (about 5 points after stable reading
Clock), read PM2.5 numerical value, record.
3, clip area is 80cm2Non-woven fabrics gauze mask segment, by non-woven fabrics gauze mask with rubber band wrap PM2.5 test
Mask effect is worn in head, simulation, and haze sample F WM1 is then sprayed on non-woven fabrics gauze mask, then starts to sample, waits reading
After stabilization (about 5 minutes), PM2.5 numerical value, record are read.
4, above-mentioned 2-3 steps are repeated, measure non-woven fabrics gauze mask successively after spraying haze sample F WM2, FWM3, FWM4
PM2.5 values and record.
5, above-mentioned 2-4 steps are repeated, measure active carbon mask, anti-particulate matter mask successively in spraying haze sample
PM2.5 values after FWM1, FWM2, FWM3, FWM4 simultaneously record.
Test result is as follows：
Note：Detection level when all equipment being allowed to be restored to normal air before each test sample.
1, it is shown according to the testing result of PM2.5 detectors, haze liquid FWM1, FWM2, FWM3, FWM4 can improve existing
There is the filter effect of mask in technology, wherein numbering：Haze liquid FWM2, FWM4 (that is to say that embodiment 2 and embodiment 4 provide
Particulate matter barrier material) be sprayed on non-woven fabrics gauze mask surface, non-woven fabrics gauze mask filter PM2.5 efficiency by 32.5% improve
Extremely>95%.
2, since the daily air quality in city where testing agency is different, so the basic data of the PM2.5 in laboratory
There is corresponding variation.But it is based on many experiments as a result, basic data daily change to detect haze liquid effect influence
It is limited.
3, the haze of haze liquid FWM2, FWM4 are very capable, and the mask for FWM2, FWM4 liquid of having sprayed can prevent
PM2.5 is passed through.
Three, challenge experiment
In order to detect the prevention ability of haze liquid newly developed to high concentration PM2.5, special 2 fragrant manufacture synthetic smoking materials
Mist, concentration are maintained at：0.407-0.216(mg/m3), i.e. 216-407 (ug/m3) range.Experimental result is tabulated below.
