Description
Technical field
The present invention is a kind of slow released ClO 2 powder being applicable to indoor air purification, is specifically related to the purified treatment of the harmful substances such as formaldehyde in indoor air, belongs to air purification field.
Background technology
Formaldehyde has another name called formaldehyde, it is a kind of colourless gas with penetrating odor, density is a little more than air, soluble in water, be a kind of organic compound of highly volatile, be mainly used in all kinds of ornament materials, such as wall covering fabric, subsides wall chemical fibre, carpet, foam plastics, paint and coating etc., therefore, be also one of the maximum indoor pollutant that is detrimental to health.In modern house environment, the concentration over-standard of formaldehyde can cause nausea, vomit, cough, uncomfortable in chest, the even symptom such as emphysema of panting, along with improving constantly of rapid development of economy and Living consumption, people are more and more higher to the comfort level of living environment, working environment, cosmetic requirements, meanwhile, the pollution problem of a series of improvement formaldehyde in indoor air is also brought.The method of existing improvement formaldehyde in indoor air mainly contains physical method, chemical method and biological method, and wherein, physical method adopts the physical measure such as ventilation, absorption, and can not produce secondary pollution, whole process is mild, consuming time longer; Chemical method then adopt can with the material of formaldehyde generation chemical reaction, produce the less novel substance of another kind of toxicity under certain condition with formaldehyde reaction or absorb formaldehyde, whole process is acutely, consuming time short, but can produce certain secondary thing pollutant; The formaldehyde pollution that biological method mainly uses plant to come in clean room's environment, by photosynthesis and the adsorption of plant, decompose formaldehyde a small amount of in air, whole process can not produce secondary pollution, but because plant is Passive intake formaldehyde, therefore, less to the effect controlling concentration of formaldehyde.
In recent years, constantly burning hot along with indoor decoration, eliminate the formaldehyde that upholstery material comes out, become people's question of common concern, and chlorine dioxide is as a kind of new and effective disinfection sanitizer, not only eliminate in the report of pollutants in air formaldehyde at many sections and carried out record, at patent documentation CN1887356 (a kind of slow released ClO 2 air disinfectant, 2007.01.03), CN2841013 (the air disinfection and refreshing box of slowly-releasing chlorine dioxide gas, 2006.11.29) in also have disclosure, mainly utilize the oxidisability of chlorine dioxide, by oxidation of formaldehyde formic acid until carbon dioxide and being removed, when using in reality, boiling point due to chlorine dioxide is only 11 DEG C, boiling point is lower, when producing, the chlorine dioxide of gaseous state exists again vivaciously and the characteristics such as instability, often need to carry out extemporaneous preparation, cause concentration wayward, therefore, result of use is unsatisfactory, if use the silica gel product that patent documentation CN1887356 discloses, then there is the defects such as complex manufacturing process, the present invention arises at the historic moment for this reason.
Summary of the invention
The object of the present invention is to provide a kind of slow released ClO 2 powder being applicable to indoor air purification, a kind of powder product of powder form is mainly provided, in actual use, its chlorine dioxide discharged can not only effectively be oxidized the formaldehyde in room air, the generation of oxidizing process non-secondary pollution thing, also has the advantages such as easy preservation, long shelf-life.
The present invention is achieved through the following technical solutions: a kind of slow released ClO 2 powder being applicable to indoor air purification, overcome in prior art and adopt silica gel to make slow released ClO 2 air disinfectant and the numerous and diverse defect of the manufacturing process that exists as colloidal powder, provide a kind of product form of powdery, the formula of described slow released ClO 2 powder is primarily of chlorine dioxide precursor, activator, slow releasing agent, gel, filler and active carbon composition, preparation process of the present invention is very simple, for subsequent use after carrying out separately drying by the component in formula, and then proportioning to carry out hybrid reaction on request, be specially adapted to industrialized large-scale production, cost of manufacture is cheap.
Further, by weight, the chlorine dioxide precursor of described composition slow released ClO 2 powder is 5 ~ 10%, activator is 12 ~ 20%, slow releasing agent is 5 ~ 10%, gel is 12 ~ 20%, filler is 43 ~ 47%, active carbon is 5 ~ 10%.
Optimize, by weight, the chlorine dioxide precursor of described composition slow released ClO 2 powder is 8%, activator is 16%, slow releasing agent is 8%, gel is 16%, filler is 45%, active carbon is 7%.
In the present invention, described chlorine dioxide precursor comprises the mixture of one or more compositions in sodium chlorite, potassium chlorite, barium chlorite, magnesium chlorite.
To better implement the present invention, described activator comprises the mixture of one or more compositions in sodium bisulfate, sodium sulfate, potassium acid sulfate, potassium sulfate, Magnesium hydrogen sulfate.
Described slow releasing agent comprises the mixture of one or more compositions in macrogol, polyvinyl alcohol, polyacrylamide, crosslinked polyethylene, this reagent is by delaying the absorption rate of moisture, reach the object of delayed response speed, thus further improve the stability of each component in formula of the present invention, avoid the generation of oneself's reaction.
For better controlling the volatility of chlorine dioxide, described gel is AQUAGEL PLUS gel.
Component of the present invention has the effect of removing the harmful substances such as formaldehyde after reaction, in real reaction process, then need moisture just can react, therefore, the present invention adds active carbon in its formula, it can active absorption moisture, delay the response speed of recipe ingredient, suitable long-time preservation, in the case, reasonable arrangement activator, slow releasing agent, gel, filler and chlorine dioxide precursor proportional amount, after mixing with moisture, the colloid containing chlorine dioxide can be obtained, simultaneously, effectively the volatility of the effective ingredient (chlorine dioxide) in powder is controlled, to meet PARA FORMALDEHYDE PRILLS(91,95) purification in room air, in the present invention, described filler is anhydrous sodium sulfate, anhydrous slufuric acid barium, anhydrous potassium sulfate, the mixture of one or more compositions in anhydrous magnesium sulfate.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) the present invention is powder product, can directly be positioned in indoor environment, the chlorine dioxide physical ability of its release is oxidized for the formaldehyde in room air, can by oxidation of formaldehyde formic acid until carbon dioxide and being removed, the generation of oxidizing process non-secondary pollution thing, practical effect is good.
(2) production method of the present invention is simple, is particularly useful for industrialized large-scale production, has the advantages such as operating process is simple, cost of manufacture is cheap.
(3) rationally, the composition of gel, slow releasing agent and filler, improves the stability in packing of product storage process all effectively, avoids reacting between each component, and reach the object extending shelf life of products, practicality is extremely strong in recipe ingredient preparation of the present invention.
(4) after the present invention uses, owing to being added with gel, therefore, after reacting with moisture in air, colloid form can be changed into by powder forms, because gel selects AQUAGEL PLUS gel, effectively can also control the rate of release of chlorine dioxide in colloid form, there is the advantages such as easy preservation, long shelf-life.
