Send out speed 0.01～8.mg/m3 h, and do not affected by temperature, humidity, highly stable.With escherichia coli in air,
Staphylococcus aureus chlorine dioxide minimal inhibitory concentration 3.6mg/m3 calculates, and slow-release time was more than 3 months.
Product of the present invention is completely isolated with air when producing, transporting.In use, replenisher can be tied by having capillary
The strip volatile matter of structure, with container outer air forming material interchange channel, utilizes capillarity, and liquid level rises, titanium dioxide
Chlorine liquid starts volatilization, and chlorine dioxide volatilizees the most therewith.Common by stable chlorine dioxide liquid replenisher system
Effect, the rate of volatilization of the chlorine dioxide that slows down greatly, reach the purpose of slow release.Increase and/minimizing strip volatile matter exposes
Gross area mode in atmosphere, to control moisture and air and this strip volatile matter exposure, controls chlorine dioxide and produces
With/release amount.
(1) production of the present invention is simple, it is simple to large-scale production, easy to use, with low cost.
(2) thickening agent in replenisher of the present invention, is cross-linked in cold water by polyvinyl alcohol and boric acid and prepares, it is not necessary to heating,
In cold water, polyvinyl alcohol and boric acid form the thin liquid of certain viscosity, resistance to oxidation, acidproof, can be stable preserve activation after
Chlorine dioxide liquid.
(3) the activator gluconic acid lactone that the present invention uses, is a kind of food additive, than conventional phosphate, sulfur
Hydrochlorate is safer.Gluconic acid lactone also has the strongest antisepsis, and in the present invention, gluconic acid lactone is activator
Also it is preservative, replenisher can be kept to deposit for a long time and never degenerate, decrease the consumption of preservative.
(4) the stabilizer beta-schardinger dextrin-that the present invention uses, can increase the dissolubility of sodium chlorite and gluconic acid lactone,
Improve chlorine dioxide concentration.The heliosensitivity of passivation chlorine dioxide, suppression replenisher muddy thing under cryogenic formation,
Shelter chlorine dioxide odor.
(5) the stabilizer Polyethylene Glycol that the present invention uses, can make hydrion and chlorition meet and generate activity two
The speed of chlorine monoxid slows down, and during replenisher volatilization, is not easily blocked strip volatile matter.
(6) replenisher of the present invention, polyvinyl alcohol and boric acid are cross-linked to form thin liquid, have stronger surface tension, and surface is opened
Power is the biggest, and capillarity is the strongest, and chlorine dioxide volatilization is the fastest, by adding paraffin oil and the silicone oil of appropriate amount, can subtract
The surface tension of few replenisher, reduces and supplements liquid level surface tension, the reduction chlorine dioxide evaporation rate of appropriateness.The most also
Air can be completely cut off, make replenisher character more stable.
(7) the strip volatile matter that the present invention uses is porous media, draws materials extensively, is not easily blocked, according to test, titanium dioxide
The rate of volatilization of chlorine replenisher length aerial to the exposure of strip volatile matter, diameter, the gross area are relevant, with strip
Which kind of material of the selection of volatile matter is without significantly association.Can be according to the difference of container material, the strip arranging in pairs or groups suitable volatilizees
Thing.
(8) present invention is acted on jointly by stable chlorine dioxide activation liquid and device, it is achieved that control chlorine dioxide release
Speed purpose, user can be different according to purposes, the difference in space, voluntarily regulation chlorine dioxide rate of volatilization, during slow release
Between extend, release concentration is steady, can accomplish timing, quantitatively.
(9) apparatus of the present invention have scale, are used for detecting chlorine dioxide rate of volatilization, when replenisher is exhausted, i.e.
Can supplement, recycle.
(10) apparatus of the present invention fully seal, and are not affected by air themperature, humidity, can be positioned over high temperature, low temperature, tide
Wet environment.Will not spill leakage when toppling over, the dense place of suitable population.
(11) replenisher of the present invention is liquid form, compared with tablet, powder, gel, more preferable with the compatibility of essence,
Odor type selects wide in range, lasting fragrance, can solve the uncomfortable sensation that chlorine dioxide penetrating odor brings.
(12) common chlorine dioxide is binary powder, gel, tablet etc., needs situ configuration, immediately during use
Use.Common release method is for using timing dispensing device or making slow release formulation.These methods also exist production loaded down with trivial details,
Relatively costly, the most affected by environment, it is impossible to realize timing, quantitative purpose.Replenisher of the present invention is two through overactivation
Chlorine monoxid stabilizing solution, production technology is simple, the most affected by environment, cheap, without compounding during use.

(3) in the above-mentioned solution titrating out A value, 2.5mol/L hydrochloric acid solution 2.5ml is added, and the 5min that opens in dark place.With
0.01mol/L sodium thiosulfate volumetric solution is titrated to blue disappearance, and record reading is B.
(4) in 500ml iodine flask, add 200ml distilled water, 1ml phosphate buffer, draw 1.0ml～10.0ml titanium dioxide
Solutions of chlorine or diluent are added in iodine flask, then pass to high pure nitrogen and are blown to yellow green disappearance, add 10ml potassium iodide
Solution, when being titrated to faint yellow with sodium thiosulfate volumetric solution, adds 1ml starch solution, continues to drop to blueness and just disappears
Till, record reading is C.
(5) in the above-mentioned solution titrating out C value, 2.5mol/L hydrochloric acid solution 2.5ml is added, and the 5min that opens in dark place.With
0.01mol/L sodium thiosulfate volumetric solution is titrated to blue disappearance, and record reading is D.
(6) adding 1ml potassium bromide solution and 10ml concentrated hydrochloric acid in 50ml iodine flask, mixing also adds 1.0ml～10.0ml bis-again
Chlorine monoxid solution, clogs bottle stopper immediately and mixes.It is placed in dark place reaction 20min, is subsequently adding 10ml liquor kalii iodide,
Acutely shake 5s, be immediately transferred in the 500ml iodine flask equipped with the saturated disodium phosphate soln of 25ml, clean 50ml
Washing liquid is also transferred in 500ml iodine flask by iodine flask, makes the last volume of solution at 200ml～300ml.Use 0.01mol/L
When sodium thiosulfate volumetric solution is titrated to faint yellow, add 1ml starch solution, continue to drop to till blueness just disappears.With
Time make blank with distilled water.Obtaining reading is E=sample readout-blank reading.
Repeat to survey 2 times, take 2 meansigma methodss and carry out calculated below.
(7) calculate
CLO2 (mg/L)=(B-D) × c × 16863 ÷ V
CLO2-(mg/L)=D × c × 16863 ÷ V
CLO3-(mg/L)=[E-(A+B)] × c × 13908 ÷ V
CL2 (mg/L)=[A-(B-D) ÷ 4] × c × 35450 ÷ V
In formula: A, B, C, D, E are sodium thiosulfate volumetric solution consumption, ml in above-mentioned each step.V is ClO 2 solution
Sample volume, ml.C is the concentration of sodium thiosulfate volumetric solution, mol/L.
Chlorine dioxide rate of release is calculated by following formula:
Its computing formula is:
W=G/ (V T)
In formula: W is rate of volatilization, mg/m3 h；
G is chlorine dioxide volatile quantity, mg；
V is volume, m3；=(S strip volatile matter cross section) × strip volatile matter is exposed to total length in air, cm；
T is release time, h；
Chlorine dioxide rate of volatilization each factor impact of chlorine dioxide device and replenisher thereof
Learn through chlorine dioxide rate of volatilization test experiments, piece cotton sliver of diameter 0.5cm, be exposed in air total
During length 1cm, chlorine dioxide rate of volatilization is 0.01mg/m3 h.Piece Medulla Tetrapanacis of diameter 0.5cm, is exposed to air
