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
the present invention relates to a kind of deodorant for refregerator material and preparation method thereof.
Background technology
domestic refrigerator is indispensable electric equipment products during people live, and almost there is refrigerator in every household.And when refrigerator is full by what fill in, various veterinary antibiotics, meat etc. are placed on for a long time in refrigerator and can produce various abnormal flavour, and this had both affected health, also destroyed the delicious food of food, and therefore the cry of people to deodorant for refregerator is more and more higher.
the foul gas produced in refrigerator mainly contains the many kinds of substances such as methanthiol, ethyl mercaptan, trimethylamine, ammonia, hydrogen sulfide.For these foul gass, many companies develop multiple deodorant for refrigerator.At present, the physisorption type deodorant for refrigerator that on market, main sale is raw material with inorganic porous materials such as active carbon, zeolite, Maifanitum and meerschaums, although these deodorizer can play certain deodorization at short notice, there is easily saturated, the shortcoming such as adsorption rate is slow, deodorizing effect is poor.Although and chemisorbed type deodorant for refrigerator has the advantage being eliminated malodor molecules by reaction, because it is applied in refrigerator, temperature is low, needs suitable reaction condition, requires high, rarely seen report.The taste removal technology used in refrigerator also has photocatalysis, but the degradation efficiency of photocatalysis to stink is lower also limit it and apply widely.Therefore, develop that adsorption capacity is large, adsorption rate be fast, can adsorb multiple foul smell and all good deodorization absorbent of effect just to become removal refrigerator peculiar smell urgently to be resolved hurrily.
