Description
Technical field
The present invention relates to a kind of deodorant, more particularly to a kind of safe efficient, environmentally friendly aircraft toilet deodorant.
Background technology
The deodorant for toilet and deodorization mode used now mainly uses spices to carry out the covering of stink, also uses thing
The method for managing absorption, is adsorbed by placing adsorbent to odorous gas molecule, so as to mitigate or remove stink, is also had
By adding the material with deodorization functions, after chemical reaction directly eliminates odorous gas, with rapidly and efficiently the features such as.Also
There are some to use biological deodorization method, mainly by microbial degradation odorant, common biological deodorization method uses biofiltration
Deodorization method and activated sludge deodorization method.
Covering method does not solve stink fundamentally, and distributing for foul smell can influence the health of the mankind；Absorption method is applied to low
Concentration height purifies desired foul gas processing, it is necessary to regularly replace adsorbent, the somewhat expensive of adsorbent, and not from root solution
The certainly generation of foul smell；The methods such as neutralization, the oxidation that chemical method passes through chemical substance, make effective deodorization composition directly and stink substance
Chemically react, but some chemical substances can cause corrosion to aircraft metal material, or shadow is caused to some elastomeric materials
Ring, so that just the airworthiness requirement for meeting aircraft, which should carry out associated materials compatibility, assesses usable.Biological deodorization method can not be fitted
Particular surroundings for aircraft toilet.

The assessment of deodoriging properties：
For ammonia, the deodorizing effect of methyl mercaptan, it is estimated using six grades of odor strength methods, it is trained by five
The person of distinguishing is smelt to being evaluated using odor strength after deodorant.
0 (nothing)：It is tasteless
1 (faint)：Though not knowing it is which kind of taste, slight stink (detection threshold value level) can be felt
2 (weak)：Smell is very weak but to differentiate it be which kind of smell (cognitive threshold level)
3 (obvious)：The smell being clearly felt that
4 (strong)：Strong stink
5 (very strong)：Insufferable strong stink
The assessment of ammonia deodorizing effect：
With filter paper impregnation 200mg wide 5cm × 0.5cm deodorant liquid, 1% ammonia spirit is impregnated on same filter paper
60mg, filter paper is uprightly put into 3L beaker, covers film, after 20 minutes, and the smell of beaker is full of with sensory evaluation.Initially
Odor strength be intensity after 5 grades, 20 minutes by five it is trained smell the person of distinguishing and evaluated, obtain its average value, decimal
Point, as odor strength, the results are shown in Table 1 using round.
Table 1
| Deodorant | Stink is evaluated |
| Embodiment 1 | 1 |
| Embodiment 2 | 1 |
| Embodiment 3 | 1 |
