Embodiment three
As shown in figure 5, a kind of automotive upholstery gas concentration smells the method for distinguishing, for automotive upholstery gas described in embodiment two
Bulk concentration, which is smelt, distinguishes instrument, and step includes:
Step 1: control device controls the gas dilution device 1 respectively and is diluted and the random outlet dress to detection gas
The gas outlet position for setting 2 pairs of diluent gas switches over, and records gas concentration and the gas outlet position of diluent gas；
In the step 1, the control device is by controlling each mass flow controller in the gas dilution device 1
15,16,19,110,111,112 the extension rate of diluent gas is controlled, to detection gas by low power number in a manner of binary
Gradually be diluted to high magnification numbe, for example, not dilute, 2 times dilution, 4 times dilution, 8 times dilution ... 128 times dilution etc. to inspection
Gas is surveyed gradually to be diluted；The control device is controlled by controlling the movement of central spindle 21 in the random air-out apparatus 2
The gas outlet position of diluent gas.
Before step 1, further includes: obtain detection gas.
In one embodiment, after automotive upholstery being placed in sampler bag, purification air is filled in sampler bag, then
After sampler bag is heated 2 hours at 80 DEG C, detection gas are obtained；Such as: 300 cubic centimetres of automotive upholstery is placed in
After in 10 liters of PVF sampler bags, it is filled with 6L purification air in sampler bag and is obtained after then heating sampler bag 2 hours at 80 DEG C
Obtain detection gas.
In another embodiment, gas collecting is carried out in the vehicle for being equipped with automotive upholstery by sampler bag, is obtained
Detection gas；Such as: 6 liters of gases are acquired in the vehicle for being equipped with automotive upholstery using 10 liters of PVF sampler bags, are detected
Gas.
Step 2: control device obtains the subjective assessment for smelling the gas odor that the personnel of distinguishing come out each gas outlet position；
In the step 2, there is a touch display screen on the control device for smelling and distinguishing that personnel's input goes out each gas outlet position
The subjective assessment of the gas odor come.
Preset subjective assessment has multiple grades in the control device.It is pre- in the control device in the present embodiment
If subjective assessment grade be divided into 6 grades, grade from gently to be respectively again without diluted " smell is imperceptible ", need 16 times it is dilute
" discernable, but can not differentiate ", 1024 times of 128 times of the need diluted " obviously discovering, can differentiate ", need diluted " spinosities released
65536 times of sharp property smell, it is difficult to receive ", need 8192 times diluted " having intense irritation smell, be difficult to endure " and need are diluted
" having intense irritation smell, can not receive ".
It smells the personnel of distinguishing and is in accordance with it and smells and distinguish that threshold value carried out screening, when screening, the n-butanol of 5ppm is successively diluted
Smell distinguishing to smelling the personnel of distinguishing to 20ppb, 40ppb and 80ppb, the gas concentration of n-butanol can still be smelt lower than 20ppb to be distinguished
Personnel belong to that smell is excessively sensitive, gas concentration be more than 80ppb can not also smell the personnel distinguished belong to have a bad nose it is quick, not
It is suitably to smell the personnel of distinguishing, to distinguish that threshold value is in 40ppb or so be that people is distinguished in more appropriate smelling is smelt to the gas concentration of n-butanol
The uniform level of member.
Step 3: control device repeats step 1 and 2, until diluent gas reaches and smells smelling for the personnel of distinguishing and distinguish threshold value, output pair
The gas concentration and/or extension rate answered.
In the step 3, the personnel of distinguishing are smelt using 6 and smell distinguishing, gas is will test and constantly dilutes, up to wherein 3 are smelt
When the personnel of distinguishing reach subjective assessment grade (smell and distinguish threshold value) of " smell is imperceptible ", gas concentration at this time and/or dilute is write down
Multiple is released, is then further continued for being diluted, until other 3 are smelt the subjective assessment etc. that the personnel of distinguishing also reach " smell is imperceptible "
When grade (smell and distinguish threshold value), gas concentration at this time and/or extension rate are write down, the two gas concentrations and/or dilution are calculated
It is finally obtained for evaluating vehicle smell and interior trim that the average value of multiple, as the automotive upholstery gas concentration smell the method for distinguishing
The gas concentration value and/or extension rate value of part smell.
The automotive upholstery gas concentration smells the method for distinguishing, is constantly diluted in a manner of binary to detection gas, and
Diluent gas comes out from two different gas outlet positions at random, for smell the personnel that distinguish carry out it is blind smell, until diluent gas reaches and smells
The person of distinguishing distinguishes threshold value to smelling for smell, and can allow smell the person of distinguishing and directly give smell the judgement distinguished, avoids fixed gas outlet position to smelling
It distinguishes that personnel generate psychological hint, improves the accuracy of evaluation.
The automotive upholstery gas concentration smells the method for distinguishing after step 3, further includes:
Step 4: the control device controls ozone generator toward leading in the detection gas air inlet pipeline of the gas dilution device 1
Enter ozone gas.
