Problems solved by technology

The disadvantage is that the shelf life is short and it is inconvenient to use
For example, various chlorine dioxide generators are complicated in equipment and high in cost, which brings a lot of inconvenience to the production, storage and transportation of chlorine dioxide, and limits the wide application of chlorine dioxide.
Also have the production of chlorine dioxide sustained-release agent and " stable " chlorine dioxide solution on the market, as described in the patent CN1175350A (publication number) is to spray chlorine dioxide solution on the carrier, dry and make preparation, when using Need to add water, acidify, namely emit chlorine dioxide; Again as described in the patent 1587029 (publication number), acid passivation is not only complex, but also needs to add water to release chlorine dioxide, although improved than before, it cannot Control the release rate of chlorine dioxide; other patents CN1238130A, CN143968A, CN1415533A, etc. are all solid chlorine dioxide preparations, which have improved the transportation, use, and safety of chlorine dioxide, but none of them have solved the problem of chlorine dioxide quantitative release , hinders the widespread application of chlorine dioxide, and also brings inconvenience to users

example 1

[0014] Dry 10 parts of sodium chlorite, 3 parts of calcium carbonate, 2 parts of sodium bicarbonate, 10 parts of carboxymethyl cellulose, 16 parts of benzyltriethylammonium chloride, 10 parts of ferric chloride, zinc chloride 8 parts, 30 parts of anhydrous aluminum trichloride, and 11 parts of diatomaceous earth were respectively added to a mixer, stirred and mixed for 30 minutes, and discharged to obtain a solid chlorine dioxide slow-release agent powder containing 6% chlorine dioxide. The above-mentioned powders are packed in sealed plastic bags of 1g / bag, 2g / bag, 5g / bag, 10g / bag, 1KG / bag, 5KG / bag as required. When in use, the packaging bag is pricked with a needle, and the powder absorbs the moisture in the environment to release chlorine dioxide slowly.

[0015] Cut the bagged solid chlorine dioxide sustained-release agent powder, put the powder in a vessel, add water (a small amount) to release chlorine dioxide quickly.

[0016] Pour the solid chlorine dioxide sustained-...

example 2

[0019] Dry 30 parts of sodium chlorite, 40 parts of benzyltriethylammonium chloride, 6 parts of ammonium sulfate, 10 parts of ferric chloride, 10 parts of aluminum trichloride, 2 parts of sodium bicarbonate, 2 parts of diatomaceous earth Pour into the mixer respectively, stir and mix for 30 minutes, and discharge. Obtain the solid chlorine dioxide sustained-release agent powder containing chlorine dioxide 18%.

[0020] Powder packing is the same as example 1.

[0021] Tablet production, packaging, storage, and use methods are the same as in Example 1.

example 3

[0023] Add 17 parts of dry sodium chlorite, 10 parts of calcium carbonate, 45 parts of octadecyltrimethylammonium chloride, 15 parts of ferric chloride, 5 parts of aluminum trichloride, and 8 parts of diatomaceous earth. In the mixer, stir and mix for 30 minutes, and discharge. Obtain the solid chlorine dioxide slow-release agent powder containing chlorine dioxide 10%.

[0024] The production, packaging, storage and use methods of powder and tablet are the same as example 1.

Abstract

A slowlly-releasing solid ClO2 for deodoring, sterilizing, disinfecting and antistaling purposes is prepared from sodium chlorite, quaternary ammonium salt, quaternary ammonium base, calcium chloride, iron chloride, aluminium sulfate, talc powder, calcium carbonate, and sodium dicarbonate through proportional mixing.

Description

(1) Technical field [0001] The invention belongs to chemical products, in particular to a solid chlorine dioxide slow-release agent. (2) Background technology [0002] Chlorine dioxide is an excellent bactericidal disinfectant, widely used in disinfection, sterilization, deodorization, and food, fruit and vegetable preservation and other fields. [0003] At present, there are many chlorine dioxide products on the market, mainly chlorine dioxide solution and its generating device. Its disadvantage is short shelf life and inconvenient use. Such as various chlorine dioxide generators, the equipment is complex and the cost of use is high, which brings a lot of inconvenience to the production, storage, transportation and use of chlorine dioxide, and limits the wide application of chlorine dioxide. Also have the production of chlorine dioxide sustained-release agent and " stable " chlorine dioxide solution on the market, as: described in patent CN1175350A (publication number) is...
