Retarding gas chlorine dioxide solid generating preparation

Abstract

The invention discloses a retarding gas chlorine dioxide solid generating preparation, comprising the following components in parts by weight: 30-100 parts of chlorite of which the purity is 80%, 20-30 parts of ascorbic acid or sodium salt derivative, 5-20 parts of pH modifier, and 5-10 parts of embedding medium. The method comprises the steps of dissolving 30-100 parts of sodium chlorite into 100-300 parts of water solution in advance, adding 5-20 parts of pH modulator and evenly agitating; pelletizing 20-30 parts of ascorbic acid or sodium ascorbate by a wet process; and feeding 5-10 parts of embedding medium into a coating pan to coat, feeding coating granules prepared in advance into the solution, lightly oscillating to evenly disperse at the same time, and generating gas chlorine dioxide after 18-600 seconds. The retarding gas chlorine dioxide solid generating preparation is simple in preparation technology, strong in operability, low in price, good in stability, and convenient to store and transport and use, and can effectively ensure the safety of operating personnel.

Description

technical field [0001] The invention relates to a solid generating preparation of gaseous chlorine dioxide disinfectant, in particular to a reaction composition for delaying the generation of gaseous chlorine dioxide. Background technique [0002] Gaseous chlorine dioxide, as the latest generation of broad-spectrum, high-efficiency and safe A1-grade disinfectant recognized internationally, has been recognized all over the world and is widely used in food processing and preservation, pharmaceuticals, hospitals, public environments, etc. Disinfection and sewage treatment and other fields. Due to the instability of chlorine dioxide, it is not easy to store and transport, and the existing solid preparation technology adopts the method of in-situ generation. Chlorine dioxide solid preparation is a kind of chlorine dioxide that can release ClO under certain operating conditions. 2 Solid products of gases. ClO 2 Solid preparations are characterized by low cost and relatively si...

But this also brings a security problem, due to the use of ClO 2 Solid preparations require on-site operation by relevant personnel

Due to the gas ClO used in the current report 2 The solid preparation method basically reacts immediately. In view of the strong oxidation and high hazard of chlorine dioxide, it is essential for the safety protection of on-site personnel. At the same time, it requires a high degree of proficiency and accuracy in operation. higher risk
