Description
Technical field
The present invention relates to a kind of disinfection sanitizer, specifically a kind of Monophyletic solid disinfectant of chlorine dioxide and preparation method thereof.
Background technology
Monophyletic solid disinfectant of chlorine dioxide be by the active ingredient sodium chlorite is coated, the means of passivation make active ingredient and solid acid does not but react with putting a place, mix the generation chlorine dioxide with water during use and the purpose that realizes sterilizing.The difference of coating, passivation means will directly influence production cost of products and serviceability.CN1439268 discloses a kind of solid chlorine dioxide disinfectant of doing clad material with organic polymer, it at first will carry out the preparation of clad material, again institute's prepared material is coated on active ingredient sodium chlorite outer surface, complex process not only, and equipment drops into high, cause production cost to improve, thereby reduced its exploitativeness and promotional value.And, owing to introduced the organic polymers such as polyvinyl alcohol of biological degradability difference, the destruction that long-term use can cause ecotope.The disclosed solid chlorine dioxide disinfectant of CN1104610A, because the covering poorly water-soluble that uses, drop into result of use when using in the water and influence finished product, also cause the solid insoluble ratio rising of disinfectant on the other hand, and the covering after the thawing also can cause water pollution.CN1238130A uses the chloride of alkali metal or alkaline earth metal to make passivator, utilize its water imbibition to reach drying purpose, to guarantee that mixing preceding sodium chlorite and solid acid with water does not react, but because the passivator water imbibition of using is strong, cause the disinfectant poor stability, holding time is short, especially one opens bag, loses efficacy soon.
Summary of the invention
Purpose of the present invention be exactly to provide that a kind of preparation technology is easy, the Monophyletic solid disinfectant of chlorine dioxide of good stability, good water solubility and preparation method thereof.
The present invention is achieved by the following technical solutions: solid chlorine dioxide disinfectant is made up of the material of following portions by weight:
Sodium chlorite 16-19, SODIUM PERCARBONATE 3-4,
Niter cake 35-38, sodium tartrate 25-31,
Citric acid and/or sulfamic acid 5-6.2, sodium bicarbonate 8.6-10.2.
Solid chlorine dioxide disinfectant of the present invention is active ingredient with the sodium chlorite, with the niter cake is activator, sodium tartrate is a passivator, citric acid and/or sulfamic acid are buffer, SODIUM PERCARBONATE is the absorption stabilizing agent, sodium bicarbonate is a blowing agent, makes made solid chlorine dioxide disinfectant good stability, and the holding time was more than 2 years.When meeting water, sodium tartrate is soluble in water, loses passivation, and citric acid and/or sulfamic acid transfer to sour environment with solution, and sodium chlorite and niter cake react, and produces chlorine dioxide.Meanwhile, the sodium bicarbonate that is dissolved in the water rapidly can produce a large amount of carbonic acid gas bubbles, in the process that bubble is overflowed, solution is played stirring action, thereby quickens the generation of chlorine dioxide.
Sodium chlorite is stable alkaline matter under drying regime among the present invention, in water body with the niter cake generation chlorine dioxide that reacts.The suitable amount ranges of sodium chlorite is 16-19.Consumption is lower than 16, can reduce the concentration of chlorine dioxide, does not reach bactericidal effect, and consumption is higher than 19, can reduce the stability of finished product.
Mesotartaric acid sodium of the present invention uses as passivator, and under drying regime, it mixes with sodium chlorite, can make the independent respectively existence of sodium chlorite and niter cake, citric acid and/or sulfamic acid, with putting a place chemical reaction does not take place.The suitable amount ranges of sodium tartrate is 25-31, and consumption is lower than 25, can reduce the stability of finished product, and content is higher than 31 reactivities that can excessively suppress niter cake, reduces conversion ratio.
Niter cake uses as activator among the present invention, and molten water is acid and the sodium chlorite generation chlorine dioxide that reacts.The suitable consumption of niter cake is 35-38, is lower than 35 and can causes conversion ratio to reduce; Be higher than 38 and make reaction too fierce, the chlorine dioxide duration of generation is short, reduces the lasting effect of sterilizing.
SODIUM PERCARBONATE is used as the absorption stabilizing agent among the present invention, is storing or the haulage stage, and when having a small amount of chlorine dioxide to produce in the medicament, this component can be a sodium chlorite with its absorbing and reducing, thus the stabilization of playing.Its suitable amount ranges is 3-4, and content is lower than stability and the safety that 3 meetings influence this finished product, and content is higher than 4 can reduce the activity ratio of niter cake and the conversion ratio of chlorine dioxide.
Citric acid and/or sulfamic acid among the present invention use as buffer, have buffering, complexing, chelating, anti-oxidant synergy and catalytic action.Its suitable amount ranges is 5-6.2, in this scope, can store safely under the drying regime, then solution can be transferred to the proper acidic environment when meeting water, thereby the chemical reaction that produces chlorine dioxide is normally carried out.Citric acid and sulfamic acid can use separately, also can mix use by arbitrary proportion.The preferential citric acid that uses separately.
Produce carbon dioxide when the sodium bicarbonate that uses among the present invention is met water, in the process that bubble is overflowed, solution is played stirring action, increase the dissolution velocity of medicament, quicken the generation of chlorine dioxide at water body.Suitable consumption is 8.6-10.2, the low effect that increases dissolution velocity that do not reach of content, and high chlorine dioxide can being taken out of of content influences bactericidal effect.
Monophyletic solid disinfectant of chlorine dioxide of the present invention uses as passivator with sodium tartrate, the environmental pollution that organic covering causes and the shortcoming of wax covering poorly water-soluble have been avoided using, compared with prior art, the present invention not only preparation technology is easy, and finished product all dissolvings in water body, water-soluble is 100%.Because the present invention does not use in the prior art the extremely strong desiccant of water imbibition such as employed magnesium sulfate to do passivator, has avoided opening a defective that lost efficacy fast in the bag back.The present invention makes the stability of finished product, safety obviously improve owing to selected unique activator and passivator, and period of storage was brought up to 2 years by 1 year.As blowing agent, solution is played stirring action with sodium bicarbonate, the carbon dioxide that is produced is nonpoisonous and tasteless, can accelerate the dissolution velocity of finished product in water, quickens the generation of chlorine dioxide.The present invention makes conversion ratio up to 99.5% owing to selected proper raw material and suitable ratio range, because the conversion ratio height, residual chlorite is few, thereby the various fields such as sterilization fresh-keeping of town and country preferably drinking water, food processing, food and drink fruits and vegetables.
Solid chlorine dioxide disinfectant of the present invention is made as follows:
A. after each component being weighed in proportion, wherein SODIUM PERCARBONATE, niter cake, sodium tartrate, sodium bicarbonate placed respectively in the warm air drier, under 100-140 ℃ of temperature, dry;
B. sodium chlorite, sodium tartrate, SODIUM PERCARBONATE and sodium bicarbonate are mixed in closed container;
C. in said vesse, add niter cake, citric acid and/or sulfamic acid, mixing;
D. with packing composition bag by bag.
The bake out temperature of above-mentioned a in the step is advisable to be no more than 140 ℃, in order to avoid raw material is by gelatinization; Be preferably 110-130 ℃, more preferably 120 ℃.Got final product in 30-40 minute 120 ℃ of general down oven dry, low excessively as temperature, then can cause drying time long, reduce production efficiency.
