Abstract
The invention discloses a nanometer TiO2 sterilizing, disinfectant and deodorant assembly for a refrigerator as well as a preparation method thereof and a disinfection and deodorization method. The nanometer TiO2 sterilizing, disinfectant and deodorant assembly comprises quartz groove plates of which the surface is coated with a TiO2 layer and a fan and an ultraviolet lamp which are arranged on the quartz groove plates. The quartz groove plates instead of the refrigerator partition plates are detachably inserted inside the refrigerator; the ultraviolet lamp and the fan are opened, and since TiO2 is a photocatalytic oxidant, TiO2 is irradiated by virtue of the ultraviolet lamp inside the refrigerator to generate strongly oxidizing radical groups under the joint action of water and oxygen in water so as to achieve the sterilizing, disinfectant and deodorant effects; the fan is used for promoting the convection of air inside the refrigerator to enhance the sterilizing, disinfectant and deodorant effects; when the quartz groove plates are used in a long term, TiO2 on the surface of the quartz groove plates can be gradually decreased so that the sterilizing, disinfectant and deodorant effects are weakened, the quartz groove plates need to be taken out, the TiO2 film on the surfaces of the quartz groove plates is removed, the prepared nanometer TiO2 solution is plated on the surfaces of the quartz groove plates again and the quartz groove plates are inserted inside the refrigerator for repeated use.
Description
Technical field
The present invention relates to the method for cold compartment of refrigerator sterilizing deodorizing, particularly refrigerator nano-TiO
2sterilizing deodorizing assembly and preparation method thereof and sterilizing and deodorizing method.
Background technology
The conventional refrigerated storage temperature of Refrigerator store food is 4 DEG C to 8 DEG C, and in such a case, most bacterial reproduction speed can slow down.But have some antibacterials and pathogenic bacteria, can not only survive under cryogenic, reproduction speed is fast all the better, even if in the refrigerating chamber of subzero about 18 DEG C, still have the very strong antibacterial of freezing tolerance to survive, this bacterium is called as psychrophile, such as yersinia, listeria spp etc.Meanwhile, these antibacterials can produce much metabolism gas in the process of growth metabolism, and as the malodoring gas such as methane, hydrogen sulfide, multiple foul smell mixes, and refrigerator can be allowed to produce unpleasant abnormal flavour.Now often adopt Maifanitum, ethanol, the method deodorization such as Linesless charcoal, but poor effect, sustainability is not strong.
Utilize nano-TiO
2photocatalysis sterilization disinfecting, deodorizing technology with its superior performance, obtain in recent years and apply widely.Result of study shows, under the effect of daylight or light middle-ultraviolet lamp, make TiO
2activate and generate the free radical with high catalytic activity, can very strong photooxidation and reducing power be produced, catalysis, photodissociation can be attached to Organic substance and the part inorganic matters such as the various formaldehyde of body surface.Nano-TiO
2there is large specific surface area, surface atom number, surface energy and surface tension sharply increase along with the decline of particle diameter, and small-size effect, skin effect, quantum size effect and macro quanta tunnel effect etc. cause the thermal and magnetic of nanoparticle, light, sensitivity characteristic and surface stability etc. to be different from conventional particle.Due to nano-TiO
2the feature that electronic structure has, makes it be subject to generate the very strong superoxide anion radical of chemical activity and hydroxyl free radical during light, attacks Organic substance, reach the effect of degradable organic pollutant.When running into antibacterial, the cell of direct aggression antibacterial, causes the organic matter degradation in bacterial cell, with this kill bacteria, and makes it to decompose.Nano titanium oxide can not only affect bacterial reproduction power, and can destroy the membrane structure of antibacterial, reaches thorough bacterium for degrading, prevents the secondary pollution that endotoxin causes.Nano-TiO
2there is very high chemical stability, heat stability, avirulence, Superhydrophilic, non-migratory, and completely can with Food Contact.Chinese patent application, its patent No. is: 2639813Y, and denomination of invention is: " the deodorization and sterilization devices of refrigerator cold-storage indoor ", disclose a kind of deodorization and sterilization device of cold compartment of refrigerator, at wire netting surface attachment nanometer titanium dioxide coating, deodorization and sterilization after ultra violet lamp.The photocatalysis characteristic that namely the method make use of nano titanium oxide preferably carrys out deodorization and sterilization, but nano titanium oxide is coated in wire netting surface, life-time service can make that nano titanium oxide is aging even to lose efficacy, user needs to regularly replace wire netting, cost is high, inconvenience, limits applying of the method.
