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 refrigerator deodorizing material and a preparation method thereof. Prepare manganese sulfate, potassium permanganate, copper-containing precursors, and magnesium-containing precursors into a solution, add molecular sieves for impregnation after mixing and reaction, dry and calcinate the molecular sieves after impregnation, and extrude the activated carbon and the calcined molecular sieves together Molding worthy of the refrigerator deodorizing material. The refrigerator deodorizing material provided by the present invention has good removal effects of methyl mercaptan, ethanethiol, trimethylamine, ammonia and hydrogen sulfide, and is combined with activated carbon to remove the peculiar smell in the refrigerator by chemical adsorption and physical adsorption respectively, making up for the respective Shortcomings.

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 ...
