Description
Affiliated technical field
The present invention relates to a kind of air sanitizer, be meant a kind of slow released ClO 2 air disinfectant specifically.
Technical background
People often live in the environment of various infectious pathogenic microorganisms and pathogenic bacteria infectivity and infection, therefore Antiepidemic sterilizing is to kill various infectious pathogenic microorganisms and antibacterial in the environment, preventing and treating eqpidemic disease infects, ensure healthy important measures, with spray disinfectant as: (peracetic acid disinfectant liquid, ClO 2 solution, liquor natrii hypochloritis) all is liquid, disinfecting time is too short, sterilisation quality's not high (taking away with air is mobile).Smoked vinegar, uviol lamp formula disinfector, trioxide disinfecting machine are present common modes to environment disinfected.But they use inconvenience, and disinfecting time is too short, and the sterilisation quality of liquid steriliser is not high, often can only play the Disinfection Effect of short time.Research and development are thorough disinfection sterilization rapidly both, and high-efficiency steriliging, the bacteriostatic sterile products that can be trapped in effective sterilization composition for a long time in the environment is current social development and the objective demand that ensures hygiene and health again.The molecule of chlorine dioxide is made up of a chlorine atom and two oxygen atoms in the ClO 2 solution, altogether in conjunction with 19 electronics, outer field key territory exists not paired activity free electron, has very strong Oxidation, amino-acid oxidase in the microprotein is decomposed, cause the amino acid chain fracture, protein loses function, thereby make microbial death, its effect is neither denaturation of proteins, neither chlorination, but powerful Oxidation, this Oxidation is stronger at least 2.5 times than chlorination.Chinese patent publication number: CN 97120902.2, open day: a WUYUEWU day in 999 year, denomination of invention " a kind of slow-release stable chlorine dioxide manufacture method of stopping admittedly " has proposed the sulfate cement grog, dead plaster, calcium oxide and stable ClO 2 solution mix mixes well the manufacture method that is frozen into the disinfection by chlorine dioxide product in the mould of falling people of back.The formed product that this method is made is good, and is free from environmental pollution during use.But adopt sulfate cement absorption ClO 2 solution, water absorption rate in its unit volume and volatilization concentration are lower, and the volume that makes product is corresponding more greatly, heavy, and can not repeat regeneration and use.As if being positioned over, ClO 2 solution directly carries out the nature volatilization in the container, can carry out the sterilizing of short time, but the evaporation rate of this solution is very fast, disinfecting time is short, the fluctuation of the concentration value of chlorine dioxide is bigger in the unit space, when concentration is high health is had harmful effect, concentration does not have the effect of sterilizing again when low, be difficult to reach the requirement of lasting, stable, long-term disinfection.And the placement of aqueous solution of chlorine dioxide and all inconvenient, also dangerous certainly.
Summary of the invention
The objective of the invention is to overcome existing in prior technology defective and deficiency, and then a kind of slow released ClO 2 air disinfectant is provided.Its volatilization concentration value is more stable, and the disinfection time is long, and is easy to use and safe and reliable.
The object of the present invention is achieved like this: a kind of slow released ClO 2 air disinfectant, and with the immobilized body of silica gel as ClO 2 solution, the weight ratio of its component is:
Exempt from reactivity or stable ClO 2 solution 1-3
Silica gel 3
The present invention can also further make the weight ratio of its component be:
Stable ClO 2 solution 1-3
Silica gel 3
Activator 0.005-0.1
The present invention can also be further with it silica gel after miscible make spherical or cylindrical or taper or hexahedral three-dimensional shape.
Activator of the present invention is citric acid or hydrochloric acid or tartaric acid.
Silica gel is a kind of high activity adsorbing material, and water insoluble and any solvent is nonpoisonous and tasteless, and chemical property is stable, does not react with any material except that highly basic, Fluohydric acid..The chemical composition of silica gel and physical arrangement, determined it to have the advantages that many other same type of material are difficult to replace, because silica gel has extremely strong adsorption to water, so the drying of being mainly used in, protection against the tide, the dehydration that can be used as dehydrant and desiccant, catalyst carrier and organic compound is made with extra care.The present invention utilizes the high-hydroscopicity of silica gel can adsorb ClO 2 solution, makes it slow volatilization, with the purpose that reaches for a long time, constantly surrounding air is carried out disinfection.And make immobilized body with silica gel, and ClO 2 solution is changed into gel by liquid, be convenient to packing, deposit and use safely.
Compared with prior art, beneficial effect of the present invention is: the 1st, and had good sustained release effect, the evaporation rate of ClO 2 solution in silica gel is even, continues, and the concentration ratio of chlorine dioxide is more suitable in the air, and slow-release period is longer.When particularly humidity was big in air, silica gel can displace the chlorine dioxide molecule by the absorption that water in air is divided, and has preserved the moisture of silica gel inside on the one hand, made it can rapid draing; Prolonged the evaporation time of ClO 2 solution on the other hand again, compared with aqueous solution of chlorine dioxide, its volatilization time can prolong 10-20 doubly, and its concentration that volatilizes the chlorine molecule is continual and steady, and disinfective action is more lasting.The 2nd, activator adopts citric acid or hydrochloric acid or tartaric acid, and is better to the activation effect of chlorine dioxide, particularly citric acid, activation ratio to ClO 2 solution is more even, and evaporation rate and volatile quantity are more stable, and action time is longer, the nonirritant abnormal flavour, better to the effect of air sterillization.The 3rd, the silica gel with it after miscible is made spherical or cylindrical or the less colloid shape of unit volume internal surface areas such as taper or hexahedron, stop flowing of ClO 2 solution, the preservation and the slow release that help ClO 2 solution also help packing, transportation and the safe handling of disinfectant products.The 4th, product of the present invention is mainly used in indoor air sterillization, can reclaim after using, and its silica gel can add the newly formed spacetabs type air sanitizers of solution weight such as chlorine dioxide once more through after the Regeneration Treatment.
The specific embodiment
Below the present invention is described in further detail by the specific embodiment:
A kind of slow released ClO 2 air disinfectant, with the immobilized body of silica gel as ClO 2 solution, the weight ratio of its component is:
Exempt from reactivity or stable ClO 2 solution 1-3
Silica gel 3
Wherein can also add an amount of activator for stable ClO 2 solution, the weight ratio of its component is:
Stable ClO 2 solution 1-3
Silica gel 3
