Embodiment 1
[0032] The invention relates to a preparation method of a slow-release chlorine dioxide powder, which overcomes the defect in the prior art that using silica gel as a colloid to make a slow-release chlorine dioxide air disinfectant is complicated, and provides a In the form of powder, this powder product can absorb and react to remove harmful substances such as formaldehyde. It has the functions of purifying the air, killing bacteria in the air, and removing odors from the air. It is mainly used as an air disinfectant and purifier.
[0033] In this embodiment, the formulation of the slow-release chlorine dioxide disinfection and purification powder mainly consists of 10% chlorine dioxide precursor, 20% activator, 5% slow-release agent, 12% gel, 45% Filler, 8% inert composition.
[0034] Make it through the following steps:
[0035] A: Prepare materials, prepare chlorine dioxide precursor, activator, slow-release agent, gel, filler and inert agent respectively:
[0036] Chlor...
Embodiment 2
[0045] In this embodiment, the formulation of the slow-release chlorine dioxide disinfection and purification powder mainly consists of 5% chlorine dioxide precursor, 12% activator, 10% slow-release agent, 20% gel, 43% Filler, 10% inert composition.
[0046] Make it through the following steps:
[0047] A: Prepare materials, prepare chlorine dioxide precursor, activator, slow-release agent, gel, filler and inert agent respectively:
[0048] Chlorine dioxide precursor selects powdery sodium chlorite for use, by weight ratio; Activator selects powdery sodium bisulfate for use; In the actual preparation process, powdered polyethylene glycol can be used; powdered AQUAGEL PLUS gel can be used as gel agent; powdered anhydrous sodium sulfate can be used as filler; activated carbon can be selected as inert agent.
[0049] B: Drying: Put the chlorine dioxide precursor, activator, filler and inert agent into a constant temperature drying box for drying and then set aside, wherein,
...
Embodiment 3
[0057] In this embodiment, the formulation of the slow-release chlorine dioxide disinfection and purification powder mainly consists of 8% chlorine dioxide precursor, 16% activator, 8% slow-release agent, 16% gel, 47% Filler, 5% inert composition.
[0058] Make it through the following steps:
[0059] A: Prepare materials, prepare chlorine dioxide precursor, activator, slow-release agent, gel, filler and inert agent respectively:
[0060] The chlorine dioxide precursor is selected from powdered sodium chlorite, potassium chlorite and barium chlorite, and the ratio of sodium chlorite: potassium chlorite: barium chlorite is 1:1:1 by weight ratio; activation The agent uses powdered sodium bisulfate, sodium sulfate and magnesium bisulfate, and the ratio of sodium bisulfate, sodium sulfate and magnesium bisulfate is 1:1:1 by weight; the purpose of the slow-release agent is to control moisture The rate of absorption has the effect of slowly absorbing water. In the actual preparati...
