Abstract
The process of preparing sterilizing granule capable of generating chorine dioxide in one package includes the following steps: preparing activating agent; mixing inorganic salt and nickel acetate, re-crystallization, sieving and deactivation; sieving and deactivating solid acid; mixing with inorganic salt; mixing sodium chlorite and cobaltous chloride, re-crystallization, sieving and deactivation; and mixing the activating agent with sodium chlorite. The product of the present invention inside one package is stable, safe, and convenient in transportation; and contains chlorine dioxide in 28 wt%, its activating rate over 95 %. The product has wide application range in drinking water, food processing, fruit and vegetable cleaning, etc.
Description
Technical field
The present invention relates to a kind of wide spectrum, efficient sterilization disinfectant preparation method, but particularly a kind of in water snap-out release go out the monobasic package sterilization preparation method of granules of dioxide peroxide.
Background technology
Dioxide peroxide is a kind of disinfection sanitizer of novel, efficient, wide spectrum, is a kind of strong oxidizer, and Application Areas is extensive, as can be applicable to town and country tap water sterilization and disinfection; Food-drink factory utensil, equipment, environment sterilization and disinfection; The sterilization of hospital's medicine equipment, environment; Aquaculture; The water of livestock rearing and environment sterilization and disinfection thereof; Waste water and wastewater disinfection; Fruits and vegetables meat egg fowl fresh-keeping etc.
From the phase later 1980s U.S. the stability chlorine dioxide aqueous solution enter China market after, because its disinfection effect is higher than used chlorinated product sanitizer far away, and dioxide peroxide can not make protein denaturation in the sterilization and disinfection process, can not produce advantages such as carcinogenic, teratogenesis, mutagenic chlorinatedorganic, enjoy people's welcome.Application Areas enlarges rapidly, and Guangdong Province, Shanghai City, Heilongjiang Province, Shanxi Province, Chongqing City hygiene department have formulated local regulation in succession, and country has also formulated stability chlorine dioxide aqueous standard [HG3669-2000].
Because chlorine dioxide content (2%) on the low side in the stability chlorine dioxide aqueous solution, and need in using to activate with acid (solid acid or liquid acid), some inconvenience brought to use.That continues has domesticly developed some in succession the novel form of dioxide peroxide can take place, as tablet, pulvis.
Mostly product about powder (grain) preparation is two-component packaging in earlier stage, the grain (seeing Chinese patent CN1238130A, CN1439268A, CN1415533A, CN1444852A) that also occurred the monobasic packing in recent years, these patents have all shown the advantage of particle (powder) the monobasic packing that can discharge dioxide peroxide in water: good stability, safety etc., but the chlorine dioxide activation rate is up to 90%, chlorine dioxide content mostly is 25% (massfraction) most in the particulate matter.
Summary of the invention
The purpose of this invention is to provide a kind of sterilization preparation method of granules that dioxide peroxide takes place, its product is monobasic packing, good stability, safe in utilization, convenient transportation, chlorine dioxide content and activation rate height, and residual chlorite is few, has enlarged range of application.
The sterilization preparation method of granules that dioxide peroxide takes place provided by the invention is characterized in that:
A, preparation activator: inorganic salt are added nickel acetate, through behind the recrystallization, screening, Passivation Treatment;
With solid acid sieve, Passivation Treatment; Mix with inorganic salt then;
B, in Textone, add cobaltous chloride after, through recrystallization, screening, Passivation Treatment;
C, with above-mentioned activator and Textone uniform mixing.
The above-mentioned raw materials composition adopts the following weight ratio:
Textone particle 44～46
Inorganic salt particle 13～17
Solid acid 38～43
Above-mentioned inorganic salt adopt a kind in monosodium phosphate, potassium primary phosphate, the sodium pyrosulfate.
Above-mentioned solid acid adopts 1～2 kind in phosphorous acid, oxalic acid, fumaric acid, tartrate, the citric acid.
Drop into the passivation raw material in the above-mentioned passivation technology and get 1～3% of the weight that feeds intake; Calcium chloride is got 1～3% of the weight that feeds intake.
The passivation raw material that uses in the passivation technology can adopt methylcellulose gum, gum arabic, Sodium Hydroxymethyl Stalcs.
The present invention compared with prior art has the following advantages: 1, realize monobasic packing, good stability, safe in utilization, convenient transportation.2, the dioxide peroxide that comprises in the particle is up to 28% (massfraction); 3, the chlorine dioxide activation rate is up to more than 95%.4, because chlorine dioxide content height, the residual chlorite of product are few, thereby enlarge its range of application, especially more be applicable to fields such as town and country tap water, food-processing, hotel, food and drink, fruits and vegetables sterilization fresh-keeping.
