Abstract
The invention discloses a platnum antibacterial and deodorant freshness-retaining block and relates to the technical field of antibacterial and freshness-retaining technology. The block is characterized in that: activated carbon fibers serve as an adsorption layer; a catalyst is carried on the activated carbon fiber; the catalyst is solution prepared from chloroplatinic acid, silver nitrate, copper nitrate, manganese nitrate and water; the activated carbon fibers are dipped in the prepared solution; and then the activated carbon fibers are dried and activated at the temperature of between 200 and 500 DEG C. In the block, a novel adsorption material, namely the activated carbon fibers serve as the adsorption layer and the carrier, and the catalysts of platinum, copper, manganese, silver and the like, is carried on the activated carbon fibers at the same time, so the functions of resisting bacteria, deodorizing, retaining the freshness of foods are achieved through the high adsorptivity and moisture absorbing and adjusting properties of the activated carbon fibers, and the catalyst characteristic of the catalysts of platinum, copper, manganese, silver and the like.
Description
Technical field
The present invention relates to the anti-bacterial refreshing technical field, be specifically related to a kind of platinum antibacterial and deodouring fresh keeping block.
Background technology
Along with the development of society and the raising of technical merit, be not only the maintenance phase of simple food and extend for the requirement of refrigerator, but had higher requirement at aspects such as taste, mouthfeel, nutrition.
At present, at frequency conversion preservation technique, super 0 ℃ of biological preservation, wide warm area is fresh-keeping, vitamin is fresh-keeping, metal ion sterilization, quick-frozen 007 fresh-keeping, many circularly coolings are fresh-keeping etc., and various fresh-keeping notion emerges in an endless stream.But it is in fact, fresh-keepingly will keep moisture exactly, realize never degenerating of nutrition, and the various fresh-keeping measures that are applied in refrigerator at present exist problem separately, and undesirable for antibiosis and deodorization effects.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of adsorbance is big, adsorption rate fast, can prevent ethene to fruit-vegetable food accelerate the ripening and microbial bacterial to the platinum antibacterial and deodouring fresh keeping block of the infringement of food.
Technical problem to be solved by this invention realizes by the following technical solutions,
A kind of platinum antibacterial and deodouring fresh keeping block, it is characterized in that: by NACF as adsorption layer, be loaded with catalyst on the described NACF, the solution that described catalyst is mixed with by chloroplatinic acid, silver nitrate, copper nitrate, manganese nitrate and water, NACF is immersed in the solution of preparation, under 200 ℃-500 ℃ temperature, carries out the drying activation behind the dipping again and get final product.
The mass parts of chloroplatinic acid, silver nitrate, copper nitrate, manganese nitrate and water is in the described catalyst,
The invention has the beneficial effects as follows: adopt NACF as the absorption main body, because NACF is a kind of novel sorbing material, its surface spreads all over micropore and has very big specific area, to various foreign odor flavor gases such as ammonia, hydrogen sulfide, methyl mercaptan, ethene and microbial bacterial all have excellent adsorption capacity, its adsorbance, adsorption rate is tens of times to hundreds of times of activated carbon granule, effectively prevented the taint of odour between the food, prevent ethene to fruit-vegetable food accelerate the ripening and microbial bacterial to the infringement of food, NACF is the moisture content in all right absorbed air in the absorption peculiar smell, thereby the humidity in the refrigerator had an ability of adjusting, when humidity is high, can absorb moisture content, when humidity is low, can discharge moisture content, but thereby the moisture content of active balance fruits and vegetables and keep freshness; And NACF is carried with the compound of platinum, copper, manganese, silver as catalyst, this catalyst has and can react with some materials such as ammonia, hydrogen sulfide, ethene etc. and with its removal, the characteristic that self is not consumed simultaneously, thereby the present invention can make things convenient for use for a long time, reaches the function of antibacterial and deodouring, food fresh keeping.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
A kind of platinum antibacterial and deodouring fresh keeping block, by NACF as adsorption layer, NACF is immersed in the solution of being prepared by chloroplatinic acid 1%, silver nitrate 1%, copper nitrate 20%, manganese nitrate 20%, water 58%, under 200 ℃-500 ℃ temperature, carries out the drying activation behind the dipping again and get final product.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
