Abstract
The invention discloses a unitary solid chlorine dioxide disinfectant and a preparation method thereof. The disinfectant comprises the following components in percentage by weight: 25-35% of sodium chlorite, 5-10% of sodium carbonate, 5-10% of sodium bicarbonate, 8-12% of calcium chloride, 25-35% of citric acid and 15-20% of malic acid. The preparation method comprises the following steps: (1) proportionally weighing the components, and respectively drying the sodium carbonate, the sodium bicarbonate, the sodium chlorite, the citric acid and the malic acid in a drying machine at 80 DEG C; (2) evenly mixing the sodium carbonate, the sodium bicarbonate, the sodium chlorite and the calcium chloride in a closed container; (3) adding the citric acid and the malic acid into the container, and evenly mixing; (4) and packaging the mixture into bags to obtain the unitary chlorine dioxide disinfectant powder, and pressing the powder by a tablet machine to obtain a tablet with the diameter of 12 mm, the thickness of 4mm and the weight of 1.0g, thereby obtaining the unitary chlorine dioxide disinfectant tablet. The unitary solid chlorine dioxide disinfectant and the preparation method thereof have the advantages of simple preparation process, high stability and favorable water solubility.
Description
One. technical field
The present invention relates to sterile products, particularly monobasic chlorine dioxide disinfector and production technology thereof.
Two. technical background
Chlorine-containing agent has had century-old history as disinfectant, and it occupies bigger share in sanitizer market always owing to factors such as its production are cheap easily, and easy to use and bactericidal effect is good.But can generate chloroform with the organic matter in the water because chlorine-containing agent has, materials such as chlorinated phenol have carcinogenic, hepatotoxicity, and effects such as nephrotoxicity, what use in the hospital at present all is organic chlorine-containing agent mostly.The chlorine-containing agent pollution on the environment more and more causes people's attention.
Chlorine dioxide (ClO
2) be that Humphrey Dai Wei found in 1811.According to the difference of concentration, chlorine dioxide is that a kind of yellow green arrives orange-red gas, has and the similar penetrating odor of chlorine, can feel when reaching 14～17ppm in the air.Boiling point is 11 ℃ during 760mmHg, and gaseous density is 3.09g/L.In the time of 0 ℃, liquid density is 1.542g/cm
3Solvability when 20 ℃ and 4Kpa dividing potential drop in water is 2.9g/L; Solvability when 20 ℃ and 10Kpa dividing potential drop in water is about 8.3g/L (and Cl
2Be about 1.5g/L), ClO
2Also be soluble in the liquid such as the carbon tetrachloride and the concentrated sulfuric acid.ClO
2Standard free energy of formation Δ G
f=+5.9KJ/mol, visible ClO
2Very unstable.ClO in gas phase
2Volumetric concentration surpasses at 10% o'clock and just has explosivity, also can explosive decomposition more than 100 ℃, but then very stable in the aqueous solution.When being subjected to ultraviolet irradiation or the Shi Zehui that is heated slowly resolves into hydrochloric acid and chloric acid.ClO
2Not hydrolysis in water, also not polymerization is than being easier to volatilization.ClO
2Be a kind of strong oxidizer, its available chlorine is Cl
22.63 times.
Chlorine dioxide is a kind of efficient, wide spectrum, safety, antibacterial disinfectant fast, and the sterilization mechanism of chlorine dioxide is: ClO
2The pair cell wall has stronger absorption and penetration capacity, and the oxidation cell includes the enzyme of dredging base effectively, synthesizes to come destroy microorganisms with what suppress microprotein apace.At four kinds of disinfection sanitizer (O commonly used
3, ClO
2, Cl
2And chloramines) ClO in
2Combination property is best, and its safety is classified as the AI level by the World Health Organization, is that a kind of chlorine of generally acknowledging in the world at present is the optimal renewal product of disinfectant.Its main dissipation characteristic is as follows:
1) sterilization wide spectrum, using dosage is low, and sterilization effect is good, speed of action is fast, the length of holding time, and has the ability polluted again of preventing;
2) in the PH scope (6～10) very strong dissipation ability is being arranged all widely, not polymerization of not hydrolysis in water, good penetrability has the effect of stripping mud;
3) generate carcinogenic poisonous chlorinatedorganics such as haloform with the organic matter effect hardly, do not generate the chloramines of Disinfection Effect difference with the ammonia effect, do not generate and detest the very big chlorophenol of smell, even also can destroy predecessor such as carcinogens such as 3,4 one BaPs with the phenol effect;
4) have the effect of good decolouring, deodorizing, control algae and foundry loam, not only can make bactericidal agent, disinfectant, also can be used as preservative and preservative agent etc.
Because the instability and the lability of chlorine dioxide, so it must on-the-spotly take place, use on the spot.Though existing stable ClO 2 solution comes out, because the factor of ease of use aspect, it also has certain limitation in application facet.Therefore the stable monobasic chlorine dioxide disinfector of developing practical safety is a key point of promoting the use of chlorine dioxide.
Three. summary of the invention
Based on above reason, the object of the present invention is to provide a kind of monobasic chlorine dioxide disinfector and production method thereof, can effectively solve: 1) the generation pollution problem of original chlorine-containing disinfectant.2) disinfectant uses trouble, the technical problem that is difficult to promote.Its solution is: adopt the sodium chlorite 25-35% of weight percent meter, sodium carbonate 5-10%, sodium bicarbonate 5-10%, calcium chloride 6-12%, citric acid 25-35%, malic acid 15-20%.
The preparation method is: 1). each component is weighed in proportion, sodium carbonate, sodium bicarbonate, sodium chlorite, citric acid, malic acid are placed respectively in the warm air drier, under 80 ℃ of temperature, dry; 2). sodium carbonate, sodium bicarbonate, sodium chlorite and calcium chloride are mixed in closed container; 3). in said vesse, add citric acid, malic acid, mixing; 4). with the mixture bag distribution packaging, this is the pulvis monobasic chlorine dioxide disinfector, with pulvis with tablet press machine be pressed into diameter 12mm, thickness 4mm, weight is the tablet of 1.0g, is the tablet monobasic chlorine dioxide disinfector.Monophyletic solid disinfectant of chlorine dioxide of the present invention and preparation method thereof preparation technology is easy, good stability, good water solubility.
