Problems solved by technology

At present, physical adsorption type refrigerator deodorants are mainly sold on the market with inorganic porous materials such as activated carbon, zeolite, medical stone and sepiolite as raw materials. Although these deodorants can play a certain deodorizing effect in a short time, However, there are disadvantages such as easy saturation, slow adsorption speed, and poor deodorization effect.
Although the chemical adsorption type refrigerator deodorant has the advantage of eliminating odor molecules by reaction, because it is used in the refrigerator, the temperature is low, and suitable reaction conditions are required, which is demanding and rarely reported.
The deodorization technology used in refrigerators is also photocatalysis, but the low efficiency of photocatalysis on odor degradation also limits its wide application

Abstract

The invention discloses a deodorizing material of a refrigerator and a preparing method of the deodorizing material. Manganese sulfate, potassium permanganate, a copper-bearing precursor and a magnesium-bearing precursor are configured into a solution, after a mixing reaction is carried out, a molecular sieve is added for dipping, the molecular sieve is dried and roasted after being dipped, active carbon and the roasted molecular sieve are formed together in an extruding mode, and the deodorizing material of the refrigerator is prepared. The deodorizing material of the refrigerator has a good effect of removing methyl mercaptan, ethyl mercaptan, trimethylamine, ammonia and hydrogen sulfide and is combined with the active carbon so that the peculiar smells in the refrigerator can be removed through chemical adsorption and physical adsorption, and the defects of chemical adsorption and the defects of physical adsorption compensate for each other.

Description

technical field [0001] The invention relates to a refrigerator deodorizing material and a preparation method thereof. Background technique [0002] Household refrigerators are indispensable electrical products in people's lives, and almost every family has a refrigerator. And when the refrigerator is full, all kinds of vegetables, fruits, meat, etc. will be put in the refrigerator for a long time to produce various peculiar smells, which not only affects hygiene, but also destroys the deliciousness of food, so people call for deodorization of refrigerators Higher and higher. [0003] The malodorous gases produced in the refrigerator mainly include methyl mercaptan, ethanethiol, trimethylamine, ammonia, hydrogen sulfide and other substances. In response to these malodorous gases, many companies have developed a variety of refrigerator deodorants. At present, physical adsorption type refrigerator deodorants are mainly sold on the market with inorganic porous materials such ...
