Problems solved by technology

Defects of this type of product: there is unsafe storage and transportation of liquid acid, direct reaction between chlorite and acid during use, resulting in explosive release and uneven release, if there is no good stabilization technology, the active sodium chlorite is easy to mix with acid Hazard due to reaction without activation
Defects of this type of product: there is free chlorine dioxide in the product, and it will continue to release chlorine dioxide even if it is not used, so that the product cannot meet the shelf life requirements required by the disinfectant; limited by the absorption capacity, the effective chlorine dioxide released by this type of product The content is very low and cannot meet the requirements of disinfection technical specifications
If activated in a small space to release a large amount of chlorine dioxide, the oxidation of chlorine dioxide may also cause damage to other items
If a large amount of chlorine dioxide cannot be exported in time, it may even cause an explosion

preparation example Construction

[0037] A preparation method for chlorine dioxide purification gel powder, comprising the following steps:

[0038] First, prepare starch polymer resin activator;

[0039] Second, mix the starch polymer resin activator, chlorite, and stabilizer in a mixer, and adjust the agent and catalyst in turn, and fully stir and mix.

[0040] The step of preparing starch polymer resin activation in the first step comprises:

[0041] S1, select the starch polymer resin matrix;

[0042] S2, acid modification, adding mixed acid to the starch polymer resin matrix, and the concentration of the mixed acid is 50-300g / L, and the mass ratio of the starch polymer resin matrix to the mixed acid is 1:5-1:500, and fully Stir slowly until dissolved;

[0043]S3, add 0.1-1% of N-methyldiethanolamine, and 1-10% of the label 50-200 polyethylene glycol, and mix uniformly; the mass percentage is based on the mass after mixing in this step;

[0044] S4, drying the mixed solution of S3 in a microwave with a...

Embodiment 1

[0053] Use 65% HPMC (hydroxypropyl methyl cellulose) and 35% CMC (carboxymethyl cellulose) as the starch polymer resin matrix, add concentration wherein to be 250g / L mixed acid solution, and citric acid is 150g in the mixed acid / L, sulfamic acid is 100g / L, and the mass ratio of matrix quality and acid is=1: 30. After mixing evenly and dissolving, add 0.1% N-methyldiethanolamine and 1% PEG 80 in total mass after mixing. Mix well, place in microwave drying equipment, and dry with 800W. Then it was pulverized to 200 mesh to obtain a starch polymer resin matrix. Then according to the mass ratio of sodium chlorite and starch polymer resin matrix of 1:5, add sodium chlorite and mix well. Then according to the mass fraction, add 10% magnesium sulfate, 25% anhydrous sodium sulfate, 1% sodium dihydrogen phosphate, 0.5% potassium phosphate, 4% sodium alginate, 1% guar gum powder, 0.5% activated alumina.

[0054] When in use, add clear water to the gel according to powder:water=1:5. ...

Embodiment 2

[0057] 60% HPMC and 40% CMC were used as a matrix, and a mixed acid solution with a concentration of 200 g / L was added thereto. In the mixed acid, citric acid is 120g / L, sulfamic acid is 80g / L, the mass ratio of substrate mass and acid is=1:50, after mixing and dissolving, add 0.2% N-methyldiethanolamine, and after mixing PEG80 with a total mass of 1.5%, mixed evenly, placed in microwave drying equipment, and dried with 800W. Then it was pulverized to 200 mesh to obtain a starch polymer resin matrix. Then according to the mass ratio of sodium chlorite and starch polymer resin matrix of 1:5, add sodium chlorite and mix well. Then according to the mass fraction, add 10% magnesium sulfate, 20% anhydrous sodium sulfate, 1% sodium dihydrogen phosphate, 0.5% potassium phosphate, 5% sodium alginate, 0.1% guar gum powder, 0.5% activated alumina.

[0058] When in use, add clear water to the gel according to powder:water=1:5. The gel can be formed within 30 seconds and can be release...

Abstract

The invention discloses chlorine dioxide purification gel powder and a preparation method thereof. The chlorine dioxide purification gel powder comprises a starch polymerization resin activator and chlorite, wherein the mass of the starch polymerization resin activator is 1 to 10 times that of the chlorite, the chlorine dioxide purification gel powder also comprises a stabilizer, a regulator and acatalyst, and the five components are uniformly mixed and are powdery. The product is safer and more stable, so that the product is more stable before being activated, and the storage life can be prolonged to 2-3 years; the product is released more uniformly; after water is added for activation, mass transfer is uniform in the reaction process, chlorine dioxide is released more stably, and the phenomenon that the content is rapidly reduced due to explosion release as soon as the chlorine dioxide is activated is avoided, and the effect is more rapid; meanwhile, due to the fact that protons andwater-absorbing resin are completely fused into a whole, under the action of a catalyst, a rapid reaction can be achieved after water is added, the effect can be achieved within 30 s, and chlorine dioxide is released; in addition, the gel powder is safe and environment-friendly, and is prepared from degradable and inorganic components; and after use, the residues are green and safe and can be treated as common garbage.

Description

technical field [0001] The invention relates to the field of disinfection products, in particular to a purification and disinfection chlorine dioxide purification gel powder and a preparation method thereof. Background technique [0002] Chlorine dioxide (ClO 2 ) is a new type of disinfectant with an oxidation-reduction potential of 1.50V and a moderate oxidation capacity. It can inactivate a variety of pathogenic microorganisms and remove harmful pollutants without causing harm to people at a lower dose. It is a A broad-spectrum, safe disinfectant and environmental purifier promoted by WHO and FAO to the world. It has been widely used in water disinfection, environmental disinfection, epidemic prevention and elimination, deodorization, air purification and other fields around the world. Disinfection and treatment effects are better than chlorine, sodium hypochlorite (84 disinfectant active ingredients), calcium hypochlorite, etc. [0003] Chlorine dioxide exists in the fo...
