Abstract
The present invention discloses a powdered CLO2 disinfectant and a preparation method thereof. The disinfectant comprises sodium chlorite, solid acidifying agents and chloride purifiers having high function of water absorption and dryness, the three materials are dried and ground into 100 meshes of powder, the chloride purifiers are uniformly and proportionally mixed with the sodium chlorite under the protection of inert gas and then bagged after being mixed with the solid acidifying agents. The solid CLO2 disinfectant packed in one bag has the advantages of simple technology and easy use. The disinfectant can be widely used for sterilizing and disinfecting drinking water, vegetables, fruits, tableware and hospitals.
Description
The present invention relates to the preparation method of disinfection agent of chlorine dioxide, be particularly for a kind of powdered CLO 2 disinfectant and preparation method thereof.
Chlorine dioxide is as a kind of antibacterial disinfectant,, safety efficient with it, extensively, have no side effect and be used widely in fields such as drinking water, food, medical treatment, environmental protection.Existing disinfection agent of chlorine dioxide is most of for separately packing, mix the bottled liquor type that uses, two bottled liquid disinfectants obviously have inconvenience in transportation, keeping and use, seek a kind of being convenient to for this reason and deposit the problem that the solid-state chloride dioxide sterilizer that transports use has become primary study exploitation in recent years, the solid-state disinfectant of multi-form chlorine dioxide constantly is pushed out appearance.Because it is many based on acidifying sodium chlorite method to produce at present disinfection agent of chlorine dioxide, and solid acidifier very easily reacts with sodium chlorite under normal condition and emits dichloride chlorine, causes the loss and the inefficacy of disinfectant.Therefore, in existing disclosed solid-state chloride dioxide sterilizer, so that sodium chlorite and solid acidifier are separated packing, what be used is in the majority.Unpack respectively to pour in the aqueous solution during use and mix, chlorine dioxide is emitted in reaction.The solid-state disinfectant of two bags of packing is given to use and is still brought some inconvenience.Chinese patent application numbers 931212448 discloses a kind of chlorine dioxide bag and production method thereof, this chlorine dioxide bag is solid acidifiers such as sodium chlorite and tartaric acid to be contained in the non-woven bag by weight make, during use the chlorine dioxide bag directly rendered in the water and get final product, it is rather convenient to use, and has realized one bag of change of solid-state chloride dioxide sterilizer.But this disinfectant a kind of river of needs when preparation is cured in vain or stearic acid thawing thing joins in the sodium chlorite, sodium chlorite is contained, isolates, make the sodium chlorite microcapsule granule, mix pack again with solid acidifier, reach the purpose that safety and stability is used, but the technology more complicated of the microcapsule granule of preparation sodium chlorite is difficult for grasping.
The objective of the invention is to overcome existing technical deficiency, it is simple to disclose a kind of technology, easily manufactured, do not need sodium chlorite is contained, covers, isolates a kind of pockaged powder type disinfection agent of chlorine dioxide that just can directly load in mixture with solid-state acidulant, to make things convenient for using and promoting of disinfection agent of chlorine dioxide.
Design of the present invention is to manage to make sodium chlorite or solid acidifier in preparing, pack, deposit the atmosphere that is in a kind of drying cmpletely in the process all the time, eliminates the external condition of solid acidifier and sodium chlorite reaction.
Task of the present invention is enabled a kind of scarvenger and is inserted in sodium chlorite or the solid acidifier and realize.
Disinfectant of the present invention includes sodium chlorite and solid acidifier, the two reaction generates (emitting) chlorine dioxide, emit inefficacy and the loss that chlorine dioxide causes disinfectant in order to stop solid acidifier and sodium chlorite to react under the non-service condition of nature, the present invention adds the chloride of a kind of alkali metal or alkaline earth metal as scarvenger in disinfectant.Chloride has very strong water imbibition and functions/drying, and itself is soluble in water, makes sodium chlorite and solid acidifier be in a kind of atmosphere of drying before using after the adding, does not possess the condition that reacts, and reaches the purpose of disinfectant safety and stability.
Solid acidifier among the present invention is anhydrous citric acid, oxalic acid or sulfamic acid, and chloride passivator used in the present invention is chlorides such as lithium chloride, calcium chloride or magnesium chloride.The concrete prescription of disinfectant following (by weight percentage) sodium chlorite: 16.7, citric acid, oxalic acid or sulfamic acid: 43.3-56.6, alkali (soil) metal halide: 26.7-40.
The concrete compound method following steps of agent toxic agent:
Get the sodium chlorite and alkali (soil) metal chloride that meet above-mentioned weight ratio, fully dry in the vacuum drying chamber of 120 degree respectively, be crushed to 100-120 purpose pulvis, alkali (soil) metal chloride joined evenly to be mixed and made into stabilizing agent in the sodium chlorite stand-by, the solid acidifier drying and crushing of the citric acid (oxalic acid or sulfamic acid) that will obtain by anharmonic ratio is to the 100-120 order, pours into evenly to mix pack in the stabilizing agent and seal.Also can earlier alkali (soil) metal chloride be joined and evenly be mixed and made into stabilizing agent in citric acid, oxalic acid or the amino acid, sodium chlorite be poured into evenly to mix to pack in the stabilizing agent again and sealed.
The batching of above-mentioned preparation process of the present invention, batch mixing and charging are to finish (also can carry out) under inert gas (chlorine) protection under vacuum state; to guarantee that solid acidifier and sodium chlorite do not react in whole process of preparation, guarantee the effective and reliable of disinfectant.During use, one packed powdery disinfectant opening is directly poured in the water, be diluted to needed concentration and get final product, the passivator in the disinfectant (chloride) dissolves in water, solid acidifier is directly emitted chlorine dioxide with the sodium chlorite reaction, the formation aqueous solution of chlorine dioxide.
The present invention has been owing to adopted the chloride of alkali (soil) metal to join in the disinfection agent of chlorine dioxide as passivator and taked inert gas shielding in operating process, realized one bag of change packing that sodium chlorite and solid acidifier directly mix effectively.Advantages such as it is simple to have preparation technology, is easy to realize, easy to use, with low cost.
Below by embodiment the present invention is described further:
Embodiment 1
Get sodium chlorite 2.5 grams; lithium chloride 4 grams; fully after the drying; be ground into 120 order pulvis; under protection of nitrogen gas, lithium chloride joined evenly to be mixed and made into stabilizing agent in the sodium chlorite stand-by, the 12-purpose anhydrous citric acids that the same drying and crushing of 8.5 grams is handled are poured into and are evenly mixed pack vacuum seal in back in the stabilizing agent (percentage by weight of above-mentioned three kinds of pulvis is respectively sodium chlorite: 16.7 again; lithium chloride: 26.7, citric acid: 56.6)
