RELEASE KIT INCLUDING CARRIER CAPABLE OF ADSORBING HIGH-CAPACITY CHLORINE DIOXIDE GAS AND PREPARATION APPARATUS CAPABLE OF PREPARING CARRIER
20210316247 · 2021-10-14 ·

The present disclosure relates to a carrier with high capacity which is capable of adsorbing a chlorine dioxide gas at high concentration and a method of preparing a release kit which is capable of releasing the chlorine dioxide gas at a certain concentration for a long period of time, and more particularly, provides a preparation method of a carrier which is capable of adsorbing a high concentration chlorine dioxide gas at high capacity and capable of maintaining a physically and chemically stable state for a long period of time, the carrier including a silica gel, i.e., an indicator material which may indicate whether or not the chlorine dioxide gas is adsorbed or desorbed, by colors; and the present disclosure provides a method capable of manufacturing a chlorine dioxide gas sterilization device which consists of a release kit enabling the chlorine dioxide gas of a certain concentration to be continuously released from the carrier for a long period of time, an internal configuration of the kit including a well-light shielded sealed container capable of storing the carrier and the indicator, an inner upper part of the sealed container containing an aromatic gel that is capable of suppressing a distinctive smell of chlorine dioxide and immersed in a super absorbent polymer, which is configured so that the release amount and the release duration can be adjusted when adjusting the hole size by forming a hole with a predetermined size in a lid of the sealed container so that the chlorine dioxide gas can be released at a certain concentration from the inside of the sealed container to the outside thereof for a long period of time, and which not only can be subminiaturized by allowing the configuration of the device to become structurally very simple when applying the kit to the sterilization device, but also is more safe and inexpensive by excluding the use of harmful chemical substances, i.e., raw materials required for generating the chlorine dioxide gas. Further, as a carrier according to the present disclosure may be reusable up to five times, the carrier has great advantages in terms of recycling of resources and maintenance costs.
