Oxidizing halogens such as chlorine or bromine can be The presence of a member is important. This halogen compound cleans or removes certain residues. Actions such as removing stains or destroying color-generating groups of organic molecules through oxidation. to do. In addition, active chlorine can kill microorganisms if it is present in high enough concentrations. , has a bactericidal effect. However, manufacturers of cleaning systems use polyalkylene oxide The cleaning system must be constructed in such a way that there is direct contact between the polymer and the active chlorine generating material. avoid This is because such contact has unfavorable effects on safety and performance. This is because the sound can be applied.

In the production of this cleaning system, many organic materials are brought into contact with active chlorine. is dangerous. At high temperatures or concentrations, organic substances become active chlorine generators. Reacts rapidly on contact, producing lots of smoke and/or fire. Also, example In the production stage, the rapid reaction between organic substances and active chlorine generating substances is suppressed. Even if the During this period, the reaction proceeds gradually, reducing the concentration of organic substances or active chlorine generating substances. It will be possible to Such reactions generally occur when the concentration of active chlorine in the cleaning system is The concentration is below that required to produce a bacterial effect or below the concentration required to remove stains. It still happens.

Furthermore, this reaction reduces the concentration of organic substances to the extent that it also reduces the properties of the organic substances. reduce

As a result, the particles are completely encapsulated by continuous coating and flow It is mobile and does not aggregate.

It is important that each particle is completely coated so that oxidizing rogens can be avoided from reacting in the environment of the cleaning system.

If dual coating is required, this dual coating can be done in a single fluidized bed. After applying the first coating, the solution tank is emptied and then the second coating is applied.
