Production method and application of stable chlorine dioxide disinfection powder

Abstract

The invention relates to a production method and application of stable chlorine dioxide disinfection powder, and provides the stable chlorine dioxide disinfection powder which is stable in chlorine dioxide content, safe, environmentally friendly and long in effective use concentration time in the use process. The chlorine dioxide disinfection powder comprises the following components by weight: 15%-30% of a generator agent, 20%-55% of an acidifying agent, 20%-35% of a drying agent, 1%-10% of a passivating agent and 0.01%-1% of a corrosion inhibitor, the generator agent is chlorite, and the metal corrosion inhibitor is a carbon quantum dot corrosion inhibitor which is researched and developed by a company and is synthesized by taking glucose and thiourea as raw materials. By adjusting the weight ratio of the components in the formula, the stability of the chlorine dioxide disinfectant is effectively improved. The product disclosed by the invention is low in production cost, simple in production process, good in stability and convenient to use, is efficient, environment-friendly, safe, stable and corrosion-inhibiting chlorine dioxide disinfection powder, and can be applied to disinfection of environments, aquaculture water bodies, livestock and poultry houses, appliances and the like.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disinfectant preparation, in particular to a production method and application of stable chlorine dioxide disinfectant powder. BACKGROUND

[0002] Chlorine dioxide is a safe, broad-spectrum bactericide, preservative and deodorant recognized internationally, and is the most ideal substitute for chlorine preparations. It has been widely used in developed countries.

[0003] Chlorine dioxide is chemically active and is easily decomposed by heat or light. It can even explode when in contact with flammable materials under high concentration conditions. So far, all attempts to compress or store chlorine dioxide, whether alone or mixed with other gases, have not been successful in commerce. Currently, chlorine dioxide is basically prepared on demand, and its storage problems and inconvenience of use have become the main factors restricting the wide application of chlorine dioxide, and have also become a subject that industry technical personnel have been trying to solve. SUMMARY

[0004] In view of the existing deficiencies, the present application provides a production method of stable chlorine dioxide disinfectant powder, which is efficient, environmentally friendly, safe, stable and corrosion-inhibiting, and has raw materials that are easy to obtain, simple process and low cost.

[0005] A production method of stable chlorine dioxide disinfectant powder, the preparation steps are as follows: chlorite, drying agent, passivation agent, activator and corrosion inhibitor are placed in a dryer and dried at 80 DEG C; first, 20% to 55% of the acidifying agent, 20% to 35% of the drying agent, 1% to 10% of the passivation agent and 0.01% to 1% of the corrosion inhibitor are mixed in a three-dimensional mixer for 30 minutes; then, 15% to 30% of sodium chlorite is placed in the three-dimensional mixer and mixed with the above-mentioned mixed materials for 30 minutes; the mixed semi-finished product is packed in an aluminum foil bag, and the air is exhausted and sealed.

[0006] The chlorine dioxide disinfectant powder in a one-pack solid state is efficient, environmentally friendly, safe in production, transportation and storage, and has raw materials that are easy to obtain, simple process and low cost.
