Description
Technical field
The present invention relates to air purifying preparation field, refer more particularly to a kind of chlorine dioxide air cleanser with sustainability.
Background technology
The air freshener sold in the market general only with fragrant come covering smell, can not purify air, the antibacterial in air can not be killed.Excellent air purifying preparation then not only will possess to be killed various harmful microorganism and eliminates the feature of noxious substance, but also should possess safety, efficient, wide spectrum, has no side effect, stores and the strong point such as easy to use.Chlorine dioxide meets above-mentioned requirements completely.Nascent oxygen and hypochlorous acid molecule can be discharged when the degerming performance of chlorine dioxide is that it contacts with microorganism, good adsorptivity and penetrance is had to microbial cell, effectively can include the enzyme of sulfenyl by oxidative cell, destructive enzyme system, make the amino-acid oxidase in protein decompose simultaneously, quick control microprotein synthesizes, the growth reaching anti-bacteria or the effect killed, also good killing action is had to spore, virus, algae, fungus, ferrum blood bacterium, sulfate reducting bacteria etc., and on higher animal cells structure completely without impact.The deodorization mechanism of chlorine dioxide is that it has extremely strong oxidisability, and oxidation-reduction potential is 1.511V, and its oxidability is 2.5 times of simple substance chlorine.Can with the many Organic substances in air and inorganic matter generation redox reaction, include machine sulfide, organic amine, phenols, aromatic hydrocarbons and unsaturated compound etc., reach and decompose abnormal flavour, the object that purifies air.
Chlorine dioxide chemical property is active, less stable.Generally the chlorine dioxide after purification is imported in the inertia solution be made up of stabilizing agent, make colourless or faint yellow clarification, colourless, odorless, stable in properties, not volatile, not labile stability chlorine dioxide aqueous solution, during use, add activator activation.But the effective release period after liquid chlorine dioxide activation is shorter, and transport, storage and use are all inconvenient.
In order to further expand purposes and the scope of application of chlorine dioxide, developed country develops solid chlorine dioxide production technology in succession in recent years, and this respect Japan is the most outstanding.Solid chlorine dioxide adopts any special measures, stable ClO 2 solution is solidificated in the novel Chlorine dioxide production of the one that carrier is prepared from.This solid chlorine dioxide goods are compared with liquid chlorine dioxide, more can extensively with effectively for relative closure space, as the place of sluggish in air circulation, the easy generation abnormal flavour such as freezer, refrigerator, bedroom, bathroom, lavatory, car, ward, also there is features such as being easy to carry, easy to use, safe simultaneously.
At present, external the aspects such as water storage sterilization, wastewater treatment, association with pulp bleaching, purification of air and food antiseptic be fresh-keeping chlorine dioxide are used for, and most widely used be purification to air, as the stink and the sterilization that use spacetabs type Low Concentration Chlorine Dioxide effectively can eliminate room air, harmless.The U.S. utilizes chlorine dioxide to carry out purification of air process by the vent of central air-conditioning to Zheng Dong building in recent years.The application of domestic current chlorine dioxide is only limitted to utilize chlorine dioxide liquid to sterilize, and the investigation and application of solid chlorine dioxide is less.The reason of restriction solid chlorine dioxide application and development is to find a kind of suitable carrier mass and slow-release material, this be due to activation after chlorine dioxide there is strong oxidizing property, the solidified carrier of many routines is invalid in this system.Find a kind of effective slow-release material, guarantee chlorine dioxide evenly, low speed, effectively discharge very difficult.
Summary of the invention
The invention provides a kind of chlorine dioxide air cleanser with sustainability, adopt adsorption sustained-release dosage form, liquid part is Stable chlorine dioxide solution, solid portion is activator, gel, slow releasing agent, chlorine dioxide solid gel is mixed to form both during use, wherein filtered out gel, suitable activator and slow releasing agent effectively easily, the chlorine dioxide gel of preparation can discharge Low Concentration Chlorine Dioxide 2 months sustainedly and stably.
