Description

Ozone sterilization indicating label and manufacturing method thereof

Technical Field

The invention belongs to the field of biological sterilization indication, and particularly relates to an ozone sterilization indication label and a manufacturing method thereof.

Background

At present, in the fields of medical instruments, daily chemicals, food safety and the like, the sterilization of the inner surface of a sophisticated instrument always depends on high-temperature steam sterilization and ethylene oxide sterilization, but the methods have inevitable defects, ethylene oxide is a generally applicable sterilizing agent and can kill various microorganisms such as tubercle bacillus, bacteria, viruses, fungi, spores and the like at normal temperature, the principle is that proper amount of ethylene oxide gas is added into a closed cabinet body by utilizing the strong sterilizing property of the ethylene oxide, so that the articles in the cabinet are sterilized, however, the residual ethylene oxide is left after the ethylene oxide sterilization and needs ventilation replacement treatment, because the ethylene oxide has flammability and explosiveness, toxic ethylene glycol is easily formed when the gas meets water at room temperature, explosion is caused when the concentration is too high, and the operation control system of the equipment is complex, the process is complicated, and the dosage, time, temperature, humidity and the like of the additive are strictly controlled.

Compared with ozone sterilization, the ozone sterilization has the advantages of safety, no corrosiveness, low cost and the like, the ozone sterilization is mainly used for sterilization and disinfection of foods, appliances and medical equipment, particularly for disinfection and disinfection of clinical endoscopes and gastroscopes, and the existing ozone disinfection cabinet with common use is to introduce ozone gas with certain concentration into a sealed cabinet at normal pressure for disinfection, but has the defects that: (1) ozone has poor permeability and incomplete sterilization, resulting in an inability to accurately determine where particular items have been missed for disposal or sterilization. (2) At present, the configuration of the instrument is more and more complex, the space of some precise parts is small, and the instrument is difficult to detect whether the sterilization is finished at the end.

Disclosure of Invention

In view of the above, the invention provides an ozone sterilization indicating label and a manufacturing method thereof, the ozone sterilization indicating card has a small card volume, is portable and sensitive in color development, and can judge whether sterilization is really finished or not through color change. The specific technical scheme is as follows:

the ozone sterilization indicating label is characterized by comprising a label color card, wherein a plurality of rectangular indicating areas are arranged on the label color card, a layer of indicating ink is coated on each rectangular indicating area, and the indicating ink comprises 24% of attachable hydrophobic resin, 36% of attachable hydrophilic resin, 2% of lubricant, 0.2% of anti-sticking agent, 10% of cleaning agent, 0.5% of bromine, 0.5% of iodine or bromine compound, 1% of compound surfactant and 20% of water.

Meanwhile, the manufacturing method of the ozone sterilization indicating label is characterized by comprising the following steps:

step one, uniformly mixing attachable hydrophobic resin, attachable hydrophilic resin, a lubricant, an anti-sticking agent, a cleaning agent, bromine, iodine or bromine compounds and water to form an indicator, and homogenizing and emulsifying the indicator at 25000rpm for 30min at 40 ℃ to prepare indicator ink;

and secondly, printing the indicating ink on the rectangular indicating area on the label color card in a gravure or silk screen mode, and drying by a room temperature fan for 30 s.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The following detailed description of embodiments of the invention is intended to be illustrative, and is intended to be illustrative only.

The ozone sterilization indicating label in the embodiment comprises a label color card, wherein a plurality of rectangular indicating areas are arranged on the label color card, a layer of indicating ink is coated on each rectangular indicating area, and the indicating ink comprises 24% of attachable hydrophobic resin, 36% of attachable hydrophilic resin, 2% of lubricant, 0.2% of anti-sticking agent, 10% of cleaning agent, 0.5% of bromine, 0.5% of iodine or bromine compound (KI or KBr), 1% of compound surfactant and 20% of water.

The following will describe the manufacturing method of the ozone sterilization indicating label, which specifically comprises the following steps:

step one, uniformly mixing attachable hydrophobic resin, attachable hydrophilic resin, a lubricant, an anti-sticking agent, a cleaning agent, bromine, iodine or bromine compounds and water to form an indicator, and homogenizing and emulsifying the indicator at 25000rpm for 30min at 40 ℃ to prepare indicator ink;

and secondly, printing the indicating ink on the rectangular indicating area on the label color card in a gravure or silk screen mode, and drying by a room temperature fan for 30 s.

After the ozone sterilization indicating label is manufactured, the ozone sterilization indicating label is placed in an ozone sterilization cabinet or attached to an object to be detected, the label color card is placed horizontally with the front side facing upwards, and after an ozone sterilization procedure, the indication ink on the label color card is changed from light yellow to purple black, which indicates that the sterilization is successful.

While specific embodiments of the invention have been described in detail with reference to exemplary embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this invention. In particular, reasonable variations and modifications are possible within the scope of the foregoing disclosure and the appended claims without departing from the spirit of the invention.
