Abstract
The present invention discloses controllable solid carrying chlorine dioxide and preparing technology thereof. The controllable solid carrying chlorine dioxide comprises a constituent A and a constituent B which are respectively packaged in packaging bags separately. When the constituent A and the constituent B, the packaging bags are opened, and the constituent A and the constituent B are put together. The present invention has the advantages that stable liquid chlorine dioxide is used as raw material, so that the controllable solid carrying chlorine dioxide has all properties of chlorine dioxide product separations; stable liquid chlorine dioxide and releasing agents are uniformly solidified on carries, and the content of different constituents can be controlled to effectively control the release property, for example, the addition of modified polyacrylic acid is controlled to control the releasing time of chlorine dioxide, the addition of sodium salt is controlled to control the time to the peak value of chlorine dioxide release, the addition of calcium salt is controlled to control the initiation time of chlorine dioxide, and the addition of gel is controlled to control the peak value of the releasing rate of chlorine dioxide, so that the controllable solid carrying chlorine dioxide can be suitable for different using environments and protected objects; the controllable solid carrying chlorine dioxide can be used after packages without needing temporary activation and is convenient to transport, store and use, and the concentration of chlorine dioxide in the air can be strictly controlled within the range between 5 and 1500 micrometers/meter<3> in effective using space, so that the chlorine dioxide is safe and convenient; the application area of chlorine dioxide products is widened greatly.
Description
Technical field
The present invention relates to a kind of disinfectant and preparation technology thereof.
Background technology
The liquid stable chlorine dioxide is classified as safe, efficient, the broad-spectrum bactericide disinfectant of IA level already by World Health Organization (WHO), now be extensive use of by most of western developed countries.The ClO that discharges after its activation
2The powerful bactericidal activity of gas is because ClO
2Itself can destroy outside the organizational structure of bacterial virus, can also play the effect of sterilizing by the atomic oxygen that decomposes, and also have good deodorizing effect, but, its application and scope are restricted because there is transportation in the liquid stable chlorine dioxide, stores and uses inconvenient shortcoming.Therefore trend adopts the solid chlorine dioxide product, two types solid chlorine dioxide product is arranged in the market, a kind of is response type, the different solid reaction raw materials and the dispersant that are about to prepare chlorine dioxide mix by a certain percentage, make it directly to take place slow chemical reaction, can in the long time, discharge chlorine dioxide, or sodium chlorite and sodium carbonate equistability auxiliary agent mixed, directly generate than stable ClO 2 solution concentration and exceed a lot of stable state solid chlorine dioxides doubly, add the stable ClO 2 solution that water is mixed with desired concn during use again, also can directly add in the entry and use; Another kind is an absorbent-type, promptly stable aqueous solution of chlorine dioxide is adsorbed onto on the solid carrier, adds other auxiliary addition agent again and is prepared into the slow-releasing solid chlorine dioxide.Though existing two kinds of solid chlorine dioxide products all can directly apply to the sterilization and the sterilization of air, the difficult effectively control of the release characteristics of the former chlorine dioxide, and store difficulty, use also cumbersome; The latter then must be earlier water-soluble, can use after activated again, and effective acting time is short, and it is extremely inconvenient to be used for air sterillization.
Summary of the invention
The purpose of this invention is to provide a kind of transportation, storage and controlled chlorine dioxide of solid carrier product easy to use.
The objective of the invention is to realize in the following way: a kind of controlled chlorine dioxide of solid carrier, form by A component and B component:
The prescription of A component thing is:
The liquid chlorine dioxide 15-25% of stability
Calcium salt 40-80%
Carboxymethyl cellulose or agar or osseocolla 0.5-10%
Modified polypropene hydrochlorate 0.5-2%
Sodium salt 0.5-4%
Deionized water 2-10%
The prescription of B component thing is
Volatile acid 0.5-3%
Calcium salt 40-80%
Carboxymethyl cellulose or agar or osseocolla 1-10%
Polyacrylate 0.5-1%
Deionized water 5-20%
A component thing and B component thing are packed respectively, during use, unpack, and A component thing and B component thing are put together to get final product.
A kind of preparation technology of controlled chlorine dioxide of solid carrier is divided into the preparation technology of A component thing and the preparation technology of B component thing:
The preparation technology of A component thing is for putting into reactor with the liquid chlorine dioxide of stability earlier, again the modified polypropene hydrochlorate is put into reactor, behind the mix homogeneously, under 35-70 ℃, add sodium salt, carboxymethyl cellulose or agar or osseocolla, deionized water, after the reaction, put into blender, add calcium salt, after stirring, molding, packing.
The preparation technology of B component thing: the volatility hydrochlorate is put into reactor, again polyacrylate is put into reactor, add carboxymethyl cellulose or agar or osseocolla and deionized water down at 35-70 ℃, after the reaction, put into blender, add calcium salt, after stirring, molding, packing.
The present invention has following beneficial effect, and the one, be raw material with the liquid chlorine dioxide of stability, have all characteristics of chlorine dioxide product.The 2nd, by evenly being solidificated in liquid chlorine dioxide of stability and releasing agent on the carrier, and can be by the content of control different component, its release characteristics is implemented effectively control, such as, the release time of the addition control chlorine dioxide by control modified polypropene hydrochlorate; Addition control chlorine dioxide by the control sodium salt discharges the time that reaches peak value; Control the initiation time of chlorine dioxide by the addition of control calcium salt; The rate of release peak value of the addition control chlorine dioxide by the control gel is to be adapted to different environments for use and object of protection.The 3rd, unpack and can use, need interim activation, transportation, store, use very convenient, and can the airborne chlorine dioxide concentration of strict control in effective usage space at 5-1500 μ m/m
3, safe and effective.The 4th, expanded the application of chlorine dioxide product greatly.The technology of the present invention index is: active ingredient chlorine dioxide: 0.1-0.4%, time to peak: 0.5-20 days, release time: 7-60 days, rate of release peak value: 50-500 μ m/m
3.h, initiation time: 0.5-48 hour, guarantee the quality storage period: 〉=1 year.
The specific embodiment
The present invention will be further described below in conjunction with embodiment:
