Problems solved by technology

If the operation procedure is wrong, put the sodium chlorite and the activator into the container and then add water, it will explode and burn, which is very unsafe
[0003] Chinese patent 02138842.3 reports "a one-package powdered stabilized chlorine dioxide and its production method" which is composed of sodium chlorite, magnesium sulfate, sodium sulfate, binary composite solid acid, but once it is transported and stored During the process, the packaging bag breaks and leaks, and the raw materials in the bag will react when they come into contact with the air, resulting in unsafe hidden dangers

Embodiment 1

[0024] Get 5 kilograms of powdery raw material sodium chlorite, 2.5 kilograms of citric acid, 10 kilograms of sodium dichloroisocyanurate respectively use 5 kilograms of 3 weight % carboxymethyl cellulose solution, 2.5 kilograms, 10 kilograms adopt boiling type granulator (produced by Shanghai Huafa Pharmaceutical Machinery Complete Set Development Co., Ltd.) according to the following method for granulation. Put 2.5 kg of powdered citric acid into the granulator, use air at a temperature of 30-60 ° C to make it turn in the granulator, and at the same time use 2.5 kg of 3% by weight carboxymethyl cellulose solution to pass through the airflow with a spray gun Spray the solution into a mist, and spray the mist into the citric acid in a stirring state, and spray for about half an hour to form citric acid particles. The granulation operation of sodium chlorite granules and sodium dichloroisocyanurate granules is the same as that of citric acid. The particle size is 20-80 mesh. ...

Embodiment 2

[0028] Get 5 kilograms of tartaric acid, 1.5 kilograms of sodium hypochlorite, use 5 kilograms of 3 weight % dextrin solution respectively, 1.5 kilograms are prepared into tartaric acid particle and sodium hypochlorite particle with the operation of embodiment 1, particle size is 20-80 order. Then use 3% by weight of hydroxypropyl methylcellulose and polyacrylic acid resin (weight ratio 15:1) solution to carry out coating in the same manner as in Example 1, and dry to obtain tartaric acid and sodium hypochlorite coated with granules. Get 5 kilograms of powdered sodium chlorite, mix it with the tartaric acid and sodium hypochlorite of the prepared granule coating with a mixer, pack in a plastic bag with 2 grams.

Embodiment 3

[0030] Dissolve 2 grams of material in the bag in 4 liters of water to obtain a disinfectant with a chlorine dioxide content of 100 mg / liter. It can be used to disinfect the surface of objects such as tables, chairs, clothes, sheets and towels, or water dispensers, for 5 minutes.

Abstract

The granulated C1O2 disinfectant consists of coated or uncoated granulated sodium chlorite, coating granulated solid acid and chlorine preparation in the weight ratio of 1 to 0.3-3 to 0.3-3. The said solid acid is oxalic acid, citric acid, tartaric acid, boric acid, methyl sulfuric acid or other acid; and the said chlorine preparation is sodium dichloroisocyanurate, symclosene, sodium chlorite, etc. The production process of the disinfectant includes pelletizing powdered materials sodium chlorite and solid acid and chlorine preparation separately; coating separately; mixing the three kinds of granulated preparation and packing. The disinfectant product is safe in use, transport and storing.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a unitary packaging granular chlorine dioxide disinfectant and a production method thereof. Background technique [0002] Chlorine dioxide is internationally recognized as an ideal new-generation chemical disinfectant. Many countries in the world have used it for sterilization and deodorization in medical and health care, food processing, food preservation, environment, drinking water, etc. It has the characteristics of no drug resistance, broad-spectrum sterilization, strong bactericidal power, no residue, and no pollution. At present, there are chlorine dioxide disinfectant products in the form of solutions, powders, tablets and other dosage forms on the market, but they need to be activated by adding an activator to release chlorine dioxide to have a strong bactericidal ability, so whether it is liquid or solid disinfection Dosage products require binary packaging. For example, in the solut...
