Problems solved by technology

CN1439268 discloses a kind of solid chlorine dioxide disinfectant with organic polymer as coating material, it will at first carry out the preparation of coating material, then the prepared material is coated on active ingredient sodium chlorite outer surface, not only process Complexity and high equipment investment lead to increased production costs, thereby reducing its implementability and promotion value
Moreover, due to the introduction of organic polymers such as polyvinyl alcohol with poor biodegradability, long-term use will cause damage to the ecological environment
The disclosed solid chlorine dioxide disinfectant of CN1104610A, due to the poor water solubility of the coating agent used, affects the use effect when the final product is put into water and uses, on the other hand also causes the solid insoluble matter ratio of disinfectant to increase, and, after melting The coating agent can also cause water pollution
CN1238130A uses the chloride of alkali metal or alkaline earth metal as passivating agent, utilizes its water absorption to reach drying purpose, to ensure that sodium chlorite and solid acid do not react before mixing with water, but because the passivating agent used has strong water absorption , leading to poor stability of the disinfectant and short storage time, especially once the bag is opened, it will soon fail

Abstract

The invention discloses a monobasic solid chlorine dioxide sanitizer and making method, which comprises the following steps: a. weighing raw material with 16-19% sodium chlorite, 3-4% sodium percarbonate, 35-38% sodium bisulfate, 25-31% sodium tartrate, 5-6.2% citrate and / or amidosulfonic acid and 8.6-10.2% sodium bicarbonate; adding sodium percarbonate, sodium bisulfate, sodium tartrate and sodium bicarbonate in the drier to dry at 100-140 deg.c; b. blending sodium chlorite, sodium tartrate, sodium percarbonate and sodium bicarbonate in the sealed container evenly; c. adding sodium bisulfate, citrate and / or amidosulfonic acid to mix evenly; d. packing composition bag by bag.

Description

technical field [0001] The invention relates to a bactericidal disinfectant, in particular to a monobasic solid chlorine dioxide disinfectant and a preparation method thereof. Background technique [0002] The monobasic solid chlorine dioxide disinfectant is achieved by coating and passivating the active ingredient sodium chlorite so that the active ingredient and the solid acid are placed in the same place without reacting, and it is mixed with water to generate chlorine dioxide when used. purpose of disinfection. The difference in coating and passivation methods will directly affect the production cost and performance of the product. CN1439268 discloses a kind of solid chlorine dioxide disinfectant with organic polymer as coating material, it will at first carry out the preparation of coating material, then the prepared material is coated on active ingredient sodium chlorite outer surface, not only process Complexity and high investment in equipment lead to increased pro...
