Abstract
The invention discloses a preparation method for a blend powder type chloro-calcium peroxide disinfectant, which belongs to the field of fine chemicals or inorganic biomaterial technology, and also belongs to the field of biomedical engineering technology. When used in water purification, the blend powder type chloro-calcium peroxide packaged in PE (polyethylene) bags or cartons is mixed by dilution with water, so as to release chlorine peroxide with strong water cleaning, disinfecting and sterilizing effects. The disinfectant can also be placed in warehouses and toilets for sterilization during sustained-release process of the disinfectant. The disinfectant is very convenient in application, and does not have any adverse effects on human body or the environment, such as teratogenic, mutagenic or carcinogenic effects.
Description
Technical field
The invention belongs to fine chemistry industry or inorganic bio technical field, also belong to the biomedical engineering technology field, concrete relate to a kind of mixed-powder type chloro-calcium hyperoxide disinfectant preparation method.
Background technology
Mixed-powder type chloro-calcium hyperoxide (Intermixing power of chlorine or calcium peroxide; Be abbreviated as PCD) disinfection sanitizer, be a kind of water quality cleansing agent that obtains with chemical method or be used for the sterilizing that warehousing, hospital and toilet etc. are located.Chlorine peroxide and calper calcium peroxide all are strong oxidizers.Ca appoints odorless, tasteless, in humid air, decomposes, bactericide, preservative, antiferment and the seed disinfectant etc. done commonly used; ClO
2(CD) chlorine dioxide of claiming more; Be after quicklime, bleaching powder, strong chlorine oil the 4th generation water disinfectant; It to bacterium, virus, mould etc. all have rapidly, killing action completely, do not see the report of the relevant bacterium that develops immunity to drugs so far, the microorganism that is not killed because find as yet so far to resist its oxidation; And CD does not have influence to the higher mammal cell structure, teratogenesis does not take place, cause change and carcinogenesis.Therefore, WHO is appointed as A1 level security disinfectant, and oneself has heterogeneous reacting to produce ClO
2Patent report (Marck Lipsztajn; Etobicoke; Canada. chlorine dioxide generating process. United States Patent; US005676920A; Oct. 14,1997), and with stable ClO 2 solution as the more compound method of main disinfection solution composition (Luxianfeng Environmental Protection Science & Technology Co., Ltd., Beijing. the production method of high purity chlorine dioxide food additives. application for a patent for invention publication number CN 1195642A).But do not see the report that the PCD disinfection sanitizer is arranged so far as yet, the sterilizing ability of PCD is stronger, and the scope of application is wider, and cost is lower and use very convenient.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, its objective is, at first, be mixed with a kind of chlorine peroxide disinfection sanitizer of solid shape, make storing all very convenient with use, cost is low again simultaneously, can extensively push away usefulness; Secondly, by means of the synergism between chlorine peroxide and the calper calcium peroxide, make the effect of sterilizing better, and the scope of application is wider.
Following for realizing the technical measures that the object of the invention adopted: 1. with sulphur silicon, villaumite and calper calcium peroxide is raw material; By following proportioning (wt. %) mix mutually, form the PCD disinfection sanitizer: sulphur silicon 25-45%, villaumite 15-30%; Calper calcium peroxide 5-15%, other filler 10-55%.
The sulphur silicon and the villaumite of proportional quantity divides 3 to 7 layers to intersect and stack, and CaO is used in the centre
2Filler such as dry powder or diatomite and sandstone is separated, and the packed or cartridge carton with biodegradable plastic respectively leaves 2-6 Φ 2-3mm water inlet air vents up and down;
2. sulphur silicon is by the 1:0.20-0.50 weight ratio concentrated sulfuric acid to be absorbed with diatomite, becomes loose solid powdery and is divided into the 2-3 layer; Villaumite by sodium chlorate and sodium chloride by 1: the 0.35-0.70 weight ratio mixes, and is divided into the 2-4 layer, uses CaO
2Dry powder or diatomite and sandstone and sulphur silicon are separated to make and are not contacted mutually and do not react;
3. adopt fresh CaO
2The on-the-spot ClO that absorbs of suspension

Embodiment
Instance 1, water-purifying sterilizing agent
Getting the 15.8ml concentrated sulfuric acid absorbs with 15g diatomite; Become loose solid powdery; Respectively get half amount be pressed into respectively 2 stratifications wide * thick * height=6.1 * 3.8 * 10.5cm press mold carton or biodegradable starch-resin plastic sack in, and be pressed into 3 layers 50g villaumite respectively (by 32g NaClO
3Be mixed with 18g NaCl) intersect and stack, middlely separate with diatomite or sandstone, every box or every bag of about 100g of material gross weight before dropping into shrimp pond, fish pond, tear lower sealing off, promptly mix immediately by the dilution of water and discharge the ClO about about 20g
2, throw in 100 bags and can make 10 mu of shrimp ponds of depth of water 1.5m contain 0.2g/m
3ClO
2Just black gill disease that arc seedling bacteriosis such as the mashed eye of culturing Penaeus monodon in the pond etc., black leg and water quality deterioration cause etc. can be killed, concentration can be suitably increased according to water quality and prawn disease deterioration degree; Promptly strengthening injected volume can significantly increase water oxygen level simultaneously, very helps forming of prawn.
Instance 2, slowly-releasing disinfection sanitizer are got the 32ml concentrated sulfuric acid and are absorbed with 18g diatomite, become loose solid powdery, and be divided into 3 parts and be laid on 30 * 7cm thin paper, be that 3 layers 50g villaumite is (by 30g NaClO with on the same size thin paper, also spreading
3With 15g NaCl and 5g CaO
2Powder is mixed and forms) intersect and to stack, be rolled into cylindrical shape then, place the PE plastic sack or the carton of bracelet mouth.Every box or every bag of material gross weight 100g contain PCD 20g, can supply 10m
3The space sterilizing.
