Embodiment Construction

[0030] (1) Weigh the following substances by weight

[0031] ①Sodium chlorite 14g

[0032] ②Sodium percarbonate 4g

[0033] ③Sodium tartrate 22g

[0034] ④ Sodium chloride 4g

[0035] ⑤ Tartaric acid 26g

[0036] (2) Put ②, ③, ④, ⑤ in the above (1) into the dryer, and dry at 50°C or 90°C or 140°C for 100 minutes;

[0037] (3), ① in the above (1) and ②, ③, ④ in the above (2) were stirred in a closed mixer for 30 minutes, and mixed;

[0038] (4), add ⑤ in the above-mentioned (2) in the airtight stirrer, continue to stir for 30 minutes, become the product;

[0039] (5) Check, weigh, subcontract and seal the product.

[0040] Testing method:

[0041] For the test method of chlorine dioxide concentration, it is recommended to use HJ / T257-2006 Appendix B, which is more accurate. If the test results of HG / T2777-1996 are used, it is not only the content of chlorine dioxide, but also the unconverted chlorite (ClO 2 - ) content, so cause the test result to be seriously on the ...

Abstract

The invention provides a single-component solid chlorine dioxide disinfector and a preparation method thereof. The single-component solid chlorine dioxide disinfector comprises the components: sodium chlorite, tartaric acid, sodium tartrate, sodium chloride and sodium percarbonate. The preparation method is as follows: the tartaric acid, the sodium tartrate, the sodium chloride and the sodium percarbonate are dried respectively; the sodium chlorite is mixed evenly with the dried sodium tartrate, the sodium chloride and the sodium percarbonate; finally, the dried tartaric acid is added into the mixture to be mixed evenly; and the processes of inspection, weighing and packing are performed. The product has the content of the chlorine dioxide more than or equal to 8 percent, the sodium chlorite rate of conversion more than 90 percent, good stability, safety, more than two years of the storage period and long effective service life.

Description

technical field [0001] The invention belongs to the technical field of antibacterial disinfectants, and relates to an improved solid chlorine dioxide disinfectant and a preparation method thereof. Background technique [0002] Chlorine dioxide is an internationally recognized high-efficiency, broad-spectrum, and residue-free next-generation ideal disinfectant. Because it does not produce carcinogenic, teratogenic, and mutagenic effects, it has been widely studied and used in various countries in the world in recent years. [0003] At present, most of the techniques for producing solid chlorine dioxide disinfectants use solid acid to acidify sodium chlorite. But sodium chlorite is very easy to react with solid acid, releasing chlorine dioxide immediately. So most of the solid chlorine dioxide disinfectants used at present are packaged separately with sodium chlorite and solid acidifier. This packaging method is very inconvenient during use.
