Description

technical field [0001] The invention belongs to the field of biological sterilization indicators, and in particular relates to a hydrogen peroxide sterilization detection indicator card and a preparation method thereof. Background technique [0002] In the life science and food industry, the aseptic cleanliness of the production environment and preparation facilities is crucial, and demand drives progress. Therefore, the corresponding sterilization technology is also constantly evolving. Traditional sterilization technologies such as formaldehyde fumigation, It is well known that formaldehyde is carcinogenic to humans. Formaldehyde sterilization usually requires 12 hours of contact time in the room, followed by a long exhaust and ventilation (about 24 hours) to reduce the harm it brings. Obviously, the sterilization Way lengthy and dangerous. In comparison, the hydrogen peroxide low-temperature plasma sterilization process is fast and has no residue, and the products produc...

Problems solved by technology

In comparison, the hydrogen peroxide low-temperature plasma sterilization process is fast and has no residue, and the products produced are only water and oxygen. This sterilization method is more practical and safe, and affects the life sciences, food and other industries. For a variety of microorganisms, the hydrogen peroxide low-temperature plasma sterilization technology has been proven to have a broad-spectrum sterilization effect, but this sterilization technology has been criticized for the accuracy of its results, and if the sterilization method is not successful, Because it is impossible to know whether the failure is caused by temperature or time or concentration, multiple trials are often required, which wastes cost and time
