Problems solved by technology

This kind of binary powder packaging method is cumbersome when used. Agent A must be completely dissolved first, then add agent B, and use after agent B is completely dissolved. The packaging method is easy to deliquescence and neutralization reaction will cause the product to fail. If it is a unitary packaging, tablets are more convenient than powders in the process of storage, transportation and use,

Embodiment 1

[0032] According to the ratio of 0.31 grams of calcium hypochlorite, 0.49 grams of malic acid, 0.1 grams of sodium sulfate, 0.1 grams of polyethylene glycol, and 0.3 grams of sodium bicarbonate, one effervescent tablet of 1 g / tablet was prepared, and the 1 gram / tablet of Put one effervescent tablet into 100ml water and dissolve it in water to make a disinfectant solution. According to the above-mentioned method for preparing disinfectant solution, increase the malic acid weight in the effervescent tablet, while other components, proportioning content are constant, prepare disinfectant solution, obtain four kinds of different disinfectants of oxidation-reduction potential (ORP). The killing effects of four different ORP disinfection solutions on Escherichia coli are shown in Table 1.

Embodiment 2

[0043] See Table 2 for the killing effect on Staphylococcus aureus using the prepared four different ORP disinfection solutions in Example 1.

[0044] Experiments have shown that for the same time of action, as the ORP value of the disinfection solution increases, the disinfection solution has a better killing effect on Staphylococcus aureus, and the logarithmic value of killing increases (Table 2).

[0047] The logarithmic value of the number of bacteria in the positive control group was 6.41

Embodiment 3

[0049] According to the ratio of 0.62 grams of calcium hypochlorite, 0.65 grams of malic acid, 0.1 grams of sodium sulfate, 0.1 grams of polyethylene glycol, and 0.28 grams of sodium bicarbonate, one effervescent tablet of 1 g / tablet was prepared, and 1 g / tablet Put an effervescent tablet into 100ml water and dissolve it in water to make a disinfection solution. According to the above-mentioned method for preparing disinfecting solution, increase the malic acid weight in the effervescent tablet, and other components, proportioning content are constant, prepare disinfecting solution, obtain five kinds of different disinfecting solutions of redox potential (ORP). See Table 3 for the killing effects of five different ORP disinfection solutions on Bacillus subtilis var. niger spores.

Abstract

The invention relates to a disinfectant effervescent tablet which can generate continuously high redox potential. The disinfectant effervescent tablet comprises the following components by weight portions: 4-8 portions of inorganic chloride salt, 8-12 portions of organic acid, 3-5 portions of one or more selected from carbonate, sodium bisulfate and hydroxylamine hydrochloride, 1-2 portions of stabilizing agent and 1-2 portions of corrosion inhibitor. The disinfectant effervescent tablet also comprises 1-2 portions of synergistic agent. An effervescent tablet of 1g/tablet is put in water and completely dissolved in 5-10 minutes to obtain 100ml-1,000ml solution; pH value of the dissolved solution is 3-7; redox potential is 800-1,200mv and concentration of available chlorine is 1000-3,000mg/L. The disinfectant of the invention is put in water; the inorganic chloride salt reacts with the organic acid to generate hypochlorous acid, nascent state chlorine, nascent state oxygen and high redox potential which interact with each other so as to greatly improve the bactericidal function; when in use, the consentration of available chlorine falls below 280ppm, which reduces side effects such as residue and irritation. The disinfectant effervescent tablet is a monobasic solid tablet, overcomes the shortcomings existing in liquid disinfectant and binary packing disinfectant, and improves largely convenience of use.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, and in particular relates to a formula and a preparation process of a disinfectant effervescent tablet that can sustainably produce high oxidation-reduction potential. Background technique [0002] The concept of oxidation-reduction potential disinfection originated from Japan's oxidation potential water (EOW) in 1987. The preparation method is that the oxidation potential water generator is generated by electrolysis of sodium chloride. The EOW generated by the machine has broad application prospects in agriculture and medical treatment ( Qiu Cuihuan. A Preliminary Study on the Sterilization Mechanism of Strongly Oxidized Ionized Water [J]. Chinese Journal of Medical Physics, 1999; 16(3): 175). my country's Ministry of Health's "Disinfection Technical Specifications (2002 Edition)" listed oxidation potential water as a new disinfection element. [0003] However, EOW itself has many weaknes...
