As can be seen from the data in table 1: the concentration of the odor gas in examples 1-12 can be reduced from the original value of 9.68 to below 0.15-1.75 within 1h, and the average is reduced to below 0.05 times of the original value, so that the cat litter deodorant has very good deodorizing effects on trimethylamine, hydrogen sulfide and ammonia gas only within 1h, and after 10h deodorizing treatment, the odor gas is reduced to below 0.001 times of the original value on average, and the deodorizing effects are stable at 11h and 12 h. The original gas concentration is about 93% after 12 hours of standing without professional deodorizing treatment. As is apparent from comparison, the targeted deodorant of the present application can treat almost all the odorous gases, and has a very remarkable deodorizing effect.
The pet sand peculiar smell deodorant prepared by the application has very high-efficiency and lasting capability of eliminating peculiar smell pollutants of pets, can reduce the peculiar smell of the pets in the closed cabin to be below the standard within 1 hour, and has no rebound; at the same time, the selection of the types of physical adsorbent and chemical absorbent can also obviously improve the elimination capability of the nano deodorizing catalyst.
The principle of the pet sand peculiar smell deodorant of the application comprises the following aspects: the physical adsorbent is mainly used for adsorbing peculiar smell of pets such as trimethylamine, hydrogen sulfide, ammonia gas and the like; the chemical absorbent is mainly used for rapidly fixing the peculiar smell of pets such as trimethylamine, hydrogen sulfide, ammonia gas and the like; the nano catalyst is mainly used for activating oxygen in air, and reacting with trimethylamine, hydrogen sulfide, ammonia and other pet peculiar smell to generate nontoxic and harmless micromolecular gas.
When the three components of the pet sand peculiar smell deodorant are used according to a specific mass ratio, better effects of quick deodorization and lasting deodorization can be obtained; has obvious effect of eliminating the peculiar smell of the pets, long duration, no generation of harmful substances, no environmental pollution, no damage to the pets and human bodies and sterilization effect.
The solid granular deodorant provided by the application can be mixed with solid pet sand for use, can be used for deodorization, is safe and non-irritating to pets, and can be reused; deodorization spraying is often adopted in the prior art, the product is not suitable for pet sand, and liquid spraying can form agglomerations on the pet sand and can cause the pet sand to be wet and moldy.
While the application has been described in terms of preferred embodiments, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the application, and it is intended that the application is not limited to the specific embodiments disclosed.
