Description
Technical Field
The invention relates to the technical field of preparation of peroxyacetic acid, in particular to a solid generating agent for preparing solid peroxyacetic acid and a preparation method and application thereof.
Background
Peroxyacetic acid is widely applied to the public and civil fields needing bleaching, sterilization and disinfection, and the principle is that an acting body is oxidized and taken off through the strong oxidizing property and high potential of the peroxyacetic acid to achieve the purpose of bleaching and disinfection, and the action of the peroxyacetic acid is larger than that of hydrogen peroxide. The existing peroxyacetic acid exists in two forms of liquid and solid, the liquid peroxyacetic acid is also called acetic acid, is a reaction product of the acetic acid and hydrogen peroxide, has simple structure and easy synthesis, is an organic acid with high activity and strong oxidizing property, has the advantages of simple process and low cost, and has the defects of easy decomposition at normal temperature, strong pungent smell, short storage time, low-temperature storage and inconvenient transportation. The liquid peroxyacetic acid is dangerous in actual use and dilution, so the liquid peroxyacetic acid has low cost and good efficiency, but is not safe, inconvenient to use and difficult to popularize in the aspect of actual application.
The solid peroxyacetic acid is actually a mixture of peroxide (sodium percarbonate, sodium perborate, urea peroxide) and an activator, hydrogen peroxide is dissolved in water after being put into water to release and temporarily react with the activator to generate peroxyacetic acid, and a receptor is oxidized by the oxidizing property of the temporarily generated peroxyacetic acid to achieve the purpose of bleaching and killing, so that compared with liquid peroxyacetic acid, the solid peroxyacetic acid has the advantages of safety, stability and long storage and transportation time, but has inferior efficiency and speed due to the defects of poor dissolution in water at normal temperature, slow reaction and volatile pH value, and because the peroxide is unstable in property, a manufacturer needs to carry out coating process granulation on the solid peroxyacetic acid, and the coated granular peroxide is difficult to dissolve in water at normal temperature and reacts very slowly, the generation speed of the peroxyacetic acid is influenced, when the peroxyacetic acid is completely dissolved and begins to release hydrogen peroxide, the hydrogen peroxide is rapidly decomposed to form oxygen due to the fact that the pH value of the hydrogen peroxide is alkaline (the hydrogen peroxide is unstable in an alkaline environment), the oxygen quickly overflows out of water and volatilizes away, the reaction quantity of the peroxyacetic acid is reduced, the generation rate is reduced, the efficiency is naturally and greatly damaged, the common problem of the existing solid peroxyacetic acid generating agent is solved, the market feedback is poor, and the peroxyacetic acid generating agent is naturally difficult to popularize and use in a large quantity.
Disclosure of Invention
The invention aims to provide a solid generating agent for preparing solid peroxyacetic acid and a preparation method and application thereof, the invention adopts a novel peroxide, namely sodium peroxysulfate, as a main component, and the novel peroxide is mixed with an activating agent and auxiliary materials into a whole according to a certain proportion.

(1) the hydrogen peroxide is firmly locked in a cage frame formed by sodium sulfate and sodium chloride to form a natural isolation layer firewall, and the cage frame is insensitive to surrounding media, so that the hydrogen peroxide is very stable.
(2) The solubility is good, because the stability is good, the coating and the granulation are not needed, the powder is very fine and smooth, the mesh number is between 120 and 150, the fluidity is good, the powder can be dissolved quickly when meeting water, oxygen is released quickly, and the powder is complete and thorough.
(3) The pH value is neutral and is between 6.5 and 7.2, which naturally does not change the original pH value of the water body, and the hydrogen peroxide is stable in state after dissolved water is separated out and is not easy to volatilize. The characteristics of the sodium peroxyacetate solid generating agent are that the sodium peroxyacetate solid generating agent invented and created by taking the sodium peroxysulfate as the main raw material is naturally characterized.
A. Because of good stability, the prepared finished product does not react and release oxygen, is safe to store and transport, has long shelf life and is not influenced by the change of air temperature, and the single-element packaging is adopted.
