Abstract
A nano modified healthy bamboo charcoal, which taking powdery bamboo charcoal of 20-400 order as main material, produced with slight nano titania and nano titania antibacterial agent. Because of porous structure and high adsorbability of bamboo charcoal, in addition to disassembling adsorbed toxic and harmful substance to carbon dioxide and water that is nontoxic and harmfulless, which is bactericide and disinfection, so the invention can clean effectively indoor air, diminish effluvium, remove dampness, resist to mildew, bactericide and disinfect, which is useful for sterilizing sterilizing ordor remover of fridge, toilet, car wagon.
Description
Technical field
The present invention relates to life health care articles for use technical field, particularly a kind of production method of nano modification taste removal bamboo charcoal.
Background technology
People because human body various stinks that produce and that food rots to produce itself fill the air in the room, influence HUMAN HEALTH in daily life.The range of product that is used to eliminate stink at present is a lot, and method is varied, and special-purpose distinguish the flavor of bacterial remover, fresh-keeping smell-absorbing device, deodorant to taste device, disinfecting deodorising device, the device for drying ﹠ deodoring etc. of going are arranged.Its method has and adopts the sorbing material taste removal, has to utilize ozone deodorization, useful filter element filtering taste removal, have and adopt Chinese medicine medicinal material taste removal, also useful chemical substance taste removal.Be specifically designed to the machine or the device of taste removal, complex structure, volume is big, the cost height.As the patent No. is 90226213 disclosed indoor multi-functional deodorant to taste devices, it is made up of housing, dust removal filter, ozonator cell, ozonizer, high tension transformer, ozone decomposition catalyst layer, fan, and volume is big, the cost height, need power supply, should not generally adopt.Device with the taste removal of Chinese medicine medicinal material, as the patent No. is device for drying ﹠ deodoring in the 01217212 disclosed footwear, it mainly is made up of housing, electric fan, electrical heating element, attaching plug and medicine Storage Box, same complex structure, and need power supply, and after the property of medicine fades away, remove and hide also reduction gradually thereupon of effect.With the chemical substance taste removal, be 94192211 disclosed " based on wool wax acid and partial glyceride remove the peculiar smell active compound composition " as the patent No., it is mainly used in the cosmetic deodorant, and after wool wax acid and partial glyceride volatilization, effect obviously reduces.And the chemical substance that has is harmful, and groups of people can produce allergy.Adopt common bamboo charcoal as the sorbing material taste removal, because the saturated shortcoming of ubiquity absorption, the time is long slightly, poor effect.
Summary of the invention
The object of the present invention is to provide a kind of energy life-time service, stable performance, the taste removal effect on moisture extraction is remarkable, and human body is not had bad harm, and cost is low, the production method of nano modification taste removal bamboo charcoal easy to use.
The objective of the invention is to be achieved through the following technical solutions: a kind of nano modification taste removal bamboo charcoal, it is a main raw material with 20-400 order particle-like bamboo charcoal, is equipped with a small amount of nano titanium oxide and nano titanium dioxide anti-bacterial agent and makes.Add man-hour, at first count size according to the bamboo charcoal order, take out nano titanium oxide in proportion, put into and become 8-9 boiling water doubly with nano titanium oxide weight, after stirring is dissolved, add nano titanium dioxide anti-bacterial agent more in proportion, stirring makes the nano titanium oxide mixed emulsion, to become with bamboo charcoal powder weight then to stir in the 1-1.5 boiling water adding bamboo charcoal powder doubly and make bamboo charcoal suspension, again bamboo charcoal suspension is injected 100 ℃ nano titanium oxide mixed emulsion, stirring makes nano modification taste removal bamboo charcoal emulsion, evaporates through routine at last, after the drying, just obtain nano modification taste removal bamboo charcoal.The content of each composition (weight) per-cent is in the taste removal bamboo charcoal: nano titanium oxide 0.5-3%, nano titanium dioxide anti-bacterial agent 0.5-1%, bamboo charcoal powder 96-99%.The bamboo charcoal order is counted size and is decided according to product requirement.Bamboo charcoal order number is big more, and the bamboo charcoal proportion is more little.
Because bamboo charcoal itself has vesicular structure and stronger characterization of adsorption, be processed into the powder shape after, specific surface area increases suddenly, thereby characterization of adsorption strengthens suddenly, deodorizing, dehumidifying, fungi-proofing effect enlarge markedly.And the nano titanium oxide in the taste removal bamboo charcoal is under the effect of light, can produce similar photosynthetic light-catalyzed reaction, produce extremely strong free radical and the active oxygen of oxidation capacity, these products can resolve into carbonic acid gas and water to organic pollutant, have antibacterial, germicidal action simultaneously.Nano titanium dioxide anti-bacterial agent is on the basis of nanometer titanic oxide material, and by the metal ion antibacterial agents such as year silver that absorption or ion-exchange method are produced, it is antibacterial, sterilizing ability is more obvious.
The taste removal bamboo charcoal that utilizes the present invention to produce can effectively purify air in the room, remove stench, and have dehumidifying, mildew-resistant, antibiotic, a germ-resistant function, can the formaldehyde, ammonia, phenmethyl etc. of absorption are poisonous, objectionable impurities is decomposed into nontoxic, harmless carbonic acid gas and water, can be widely used in the aseptic deodovization agent of refrigerator disinfecting, the toilet aseptic deodovization agent of sterilization in aseptic deodovization agent, the car of sterilizing, human body is not had bad harm.Possess capacity of decomposition owing to this taste removal bamboo charcoal simultaneously, but taste removal bamboo charcoal life-time service does not need the cool flushing of shining, and can keep original bamboo charcoal atomic structure, keeps the strong absorption property of original bamboo charcoal.In addition, this taste removal charcoal is easy to use, can arbitrarily be positioned over the place that needs taste removal, and cost is low, is easily accepted by consumers in general.
Embodiment
A kind of nano modification taste removal bamboo charcoal, it is a main raw material with 20-400 order particle-like bamboo charcoal, is equipped with a small amount of nano titanium oxide and nano titanium dioxide anti-bacterial agent and makes.Adding man-hour, at first the bamboo section of being cut into is put into stove at secluding air or feed under the condition of little air and heat, is that 600-800 ℃ conventional pyrolytic process is made bamboo charcoal with final carbonization temperature, is ground into 20-400 purpose particle-like bamboo charcoal then.Count size according to the bamboo charcoal order again, take out nano titanium oxide in proportion, put in the boiling water of 8-9 times of nano titanium oxide weight, make its off-bottom after stirring 20-30min, and then add nano titanium dioxide anti-bacterial agent in proportion, behind the restir 10-30min, make the nano titanium oxide mixed emulsion.Used bamboo charcoal order number is big more, and nano titanium oxide and nano titanium dioxide anti-bacterial agent consumption are big more.The bamboo charcoal powder of again order of relevant nanometer amount of titanium being counted scope adds to stir in the boiling water that becomes 1-1.5 times with bamboo charcoal powder weight and makes bamboo charcoal suspension.At last bamboo charcoal suspension is injected 100 ℃ nano titanium oxide mixed emulsion, stir 30min, just make nano modification taste removal bamboo flavor emulsion.After taking-up nano modification taste removal bamboo charcoal emulsion is carried out routine evaporation, drying, promptly obtain black nano modification taste removal bamboo charcoal.
