specific Embodiment approach 1

[0015] Specific embodiment 1: This specific embodiment adopts the following technical solutions: its preparation method: 1) prepare a mixed solution; quantitatively weigh 127 grams of bisacrylamide, 3673 grams of acrylamide, and 80% chlorous acid according to the weighing table Sodium 4750g, borax 760g and potassium persulfate 38g, respectively, dissolved in deionized water, of which 127g of bisacrylamide and 760g of borax were dissolved in 5 liters of hot water at about 70℃ respectively, and stirred for about 7 minutes to completely dissolve , Pour them slowly into a large bucket to mix, and finally add the overcurrent potassium acid solution, stirring while adding to avoid local concentration. Add water to make the volume up to 76 liters to obtain a mixed solution with a pH of 9.3;

[0016] 2) Solidify; divide the mixed solution into 80ml bottles according to the 60ml / bottle, add one drop (50ul) of tetramethylethylenediamine to each bottle, stir and mix immediately, and let sta...

specific Embodiment approach 2

[0019] Specific embodiment two: This specific embodiment is different from specific embodiment one in: its preparation method, 1) prepare a mixed solution; quantitatively weigh 304 grams of bisacrylamide and 5776 grams of acrylamide according to the weighing table. 80% sodium chlorite 4750 grams, 1900 grams borax and 38 grams of potassium persulfate were dissolved in deionized water. Among them, 304 grams of bisacrylamide and 1900 grams of borax were separately stirred with 5 liters of hot water at 70°C. Dissolve completely in about 7 minutes, slowly pour them into a large bucket to mix, and finally add the overcurrent potassium acid solution, stirring while adding to avoid excessive local concentration. Add water to make the volume up to 76 liters.

[0020] The following steps 2) and 3) are the same as the steps 2) and 3) of the first embodiment.

[0021] The parameters of the product made in this specific embodiment: gel pH 9.3, 5% sodium chlorite (theoretical equivalent to 3% c...

Abstract

The invention provides a preparation method of controllable and visual chlorine dioxide slow-release gel, and relates to the technical field of gas sterilization and deodorization. The method comprises the steps of respectively dissolving water-soluble materials including sodium chlorite, acrylamide, bisacrylamide, borax, potassium persulfate and the like, mixing in proportion, carrying out split charging, then feeding tetramethylethylenediamine, and carrying out polymerization reaction to obtain the polyacrylamide gel. When the controllable and visual chlorine dioxide slow-release gel is used, a matched acidification rod is inserted into the gel, and chlorine dioxide gas can be slowly released, so that the effects of sterilization and deodorization for the surrounding environment can be achieved. The method has the characteristics that the slow-generation and slow-release speed of the chlorine dioxide can be controlled by controlling the concentrations of the gel and the borax, the degree of crosslinking of the gel and the type of the acidification rod; the gel at the rear end of the product is formed by polymerization and is colorless and transparent, thus being suitable for various shapes; after the product is acidized and activated, the gel becomes yellow from colorless, the chroma of the gel is in direct proportion to the concentration of the chlorine dioxide, and vice versa, so that the gel also has the function of ClO2 indicator; after the product is acidized and activated, the released gas does not contain toxic by-product chlorine.

Description

[0001] Technical field [0002] The invention relates to the technical field of gas sterilization and deodorization, in particular to a controllable visible chlorine dioxide slow-release gel and a preparation method. Background technique [0003] As a strong oxidant, chlorine dioxide has a strong ability to adsorb and penetrate the cell wall of microorganisms. It can effectively oxidize the enzymes containing sulfhydryl groups in the cells. It can also quickly inhibit the synthesis of microbial protein to achieve the effect of sterilization and disinfection. The recognized fourth-generation high-efficiency disinfectant. It can kill all microorganisms, including bacterial propagules, bacterial spores, fungi, mycobacteria and viruses, etc., and its safety is rated as AI level by the World Health Organization (WHO). At the same time, its strong oxidizing property can also oxidize and degrade some toxic and odorous gas substances in the surrounding environment, such as formaldehyde, ...
