Description
Technical Field
The invention relates to chemical indicating ink, in particular to a chemical indicating ink for monitoring A0Chemical indicator ink of value and its useThe preparation method belongs to the technical field of chemical monitoring of damp-heat disinfection effect.
Background
The moist heat sterilization method is a method of sterilizing with saturated steam, boiling water or circulating steam, and high temperature and high pressure steam is used as a medium, and because of large latent heat of steam and strong penetrating power, protein is easily denatured or coagulated, and finally, microorganisms are killed. A. the0The value is an index for evaluating the effect of moist heat sterilization, and means that the temperature corresponds to a time (second temperature) of 80 ℃ when the effect of killing microorganisms expressed by Z value is 10K. A. the0The value 600 is the minimum standard requirement for sterilization of a multiplexed cleaning tool. RKI (Robert Koch, Germany) was proposed in 1999 for a disinfection program that targets bacteria, including mycobacteria, molds and thermotolerant viruses A0The value is specified as 600, which corresponds to 80 ℃/600sec, 10min, 90 ℃/1min, and the like. If the effect of killing heat-resistant viruses such as hepatitis B virus HBV is to be ensured, a program with higher disinfection level is selected, A0The value is 3000 corresponding to 90 deg.C/5 min, etc. The general application of this type of procedure to surgical instruments is suggested, and this standard has a wide impact on the establishment of european standards for thermal disinfection. With the development of disinfection technology, various types of cleaning disinfectors are more and more widely applied. The thermal disinfection in the cleaning sterilizer is to disinfect the objects to be disinfected by using hot water to spray and wash. The temperature of damp-heat sterilization is more than or equal to 90 ℃, and the time is more than or equal to 5min, or A0More than or equal to 3000; and (5) continuing sterilization treatment after disinfection. The temperature of heat sterilization is more than or equal to 90 ℃, and the time is more than or equal to 1min, or A0≥600。A0The value is used as an index for evaluating the damp-heat disinfection effect, in the prior art, the calculation is mainly carried out by using a physical method, but in the actual operation, a plurality of factors, such as instrument loading capacity, the running speed of a spray arm, water temperature and the like, can influence the value, and the calculation result is inaccurate. In addition, the existing sterilizer contains strong oxidant, such as hydrogen peroxide sterilizer, which can oxidize the conventional chemical indicator caine to change color, and cause inaccurate sterilization result display. In addition, some chemical indicating ink can not resist high temperature, and some chemical indicating ink even contains heavy metal which causes harm to human bodies and environment. Thus, how to prepare a display stabilizerAnd the chemical indicating ink for monitoring without harm to the environment is a technical problem to be solved urgently in the technical field of chemical monitoring of wet and hot disinfection effects.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a method for monitoring A0The invention discloses a chemical indicating ink with a value, which solves the problems that the traditional chemical indicating ink is easy to oxidize, inaccurate in display, not high-temperature resistant and harmful heavy metals are contained to harm the environment.
The invention relates to a method for monitoring A0Chemical indicating ink of value, made of the following raw materials in percentage by weight:
10-25% of a connecting material;
30-50% of a solvent;
0.5 to 2.0 percent of color developing agent;
1.0-20% of alkaline auxiliary agent;
1.0 to 3.0 percent of filler;
1.0-10% of thickening agent.
Wherein:
the binder is one or a mixture of polyethylene resin, polyvinyl chloride resin, acrylate resin, phenolic resin, polyester resin or polyamide resin.
The solvent is one or a mixture of propylene glycol diacetate, ethylene glycol monoethyl ether acetate and ethylene glycol diacetate.
The color developing agent is bromocresol green or neutral red.
The alkaline auxiliary agent is one or a combination of more of sodium carbonate, sodium bicarbonate, potassium carbonate, calcium carbonate and basic magnesium carbonate.
The filler is one or a combination of more of calcium carbonate, talcum powder, barium sulfate and aluminum hydroxide.
The thickening agent is one or a combination of more of sodium carboxymethylcellulose, starch and sodium alginate.
The preparation method of the ink is characterized by comprising the following steps: the method comprises the following steps: fully mixing the connecting material and the solvent for dissolving, wherein the adding sequence of other raw materials is as follows: developer, alkaline assistant, filler and thickener, and finally stirring and grinding to obtain the product.
The grinding is carried out by adopting a three-roll grinder until the fineness is less than 20 micrometers measured by a scraper fineness meter.
The gravure, silk screen, flexible plate or offset plate for the printing ink is printed on a high-temperature-resistant and waterproof material to prepare the material for monitoring A0The chemical value indicates the product, and the surface of the waterproof high-temperature-resistant card is covered with a layer of high-temperature-resistant film, and the thickness of the film is 15-25 mu m.
The waterproof high-temperature-resistant card comprises PET, BOPP, PVC and the like, and the thickness range is 0.2mm-0.3 mm.
A0The chemical indicator card color change principle of the values is as follows: with the rising of the water temperature in the washer disinfector, A0The pore diameter of the membrane on the surface of the chemical indicator card is increased, and hot water penetrates through the membrane to contact with ink to react to generate color change. Judgment of A by color change0The value is further judged to determine the disinfection effect.
Compared with the prior art, the invention has the beneficial effects that: to prepare A0The value chemical indicator card is used in cleaning sterilizer, and the A is judged by chemical reaction0The disinfection effect is judged by the value, and the calculation of A by using a physical method is avoided0The calculation result is inaccurate when the value is obtained. A prepared by the invention0The value chemical indicator card has stable color change and small error after being subjected to damp-heat sterilization by a cleaning sterilizer, and can fully verify that A is a0Whether the value meets the requirements. The ink prepared by the invention can be used for different inks A by adjusting the component proportion0The monitoring requirement of the value guarantees the requirements of different sterilization effects of hospitals. The printing material adopted by the invention is a waterproof high-temperature-resistant material, so that deformation is avoided in the sterilization process, and the surface is coated with a high-temperature-resistant film, so that air isolation is more stable. In addition, the ink prepared by the invention does not contain heavy metal components, and does not harm human bodies and the environment. Thus, the A0The value chemical indicator card can reflect the disinfection effect more safely, directly and accurately.

24% of phenolic resin;
ethylene glycol diacetate 50%;
19% of calcium carbonate;
1.0% of bromocresol green;
4.0 percent of aluminum hydroxide;
and 2.0 percent of sodium alginate.
The preparation method comprises the following steps:
firstly, mixing phenolic resin and ethylene glycol diacetate, stirring until the phenolic resin is completely dissolved in the ethylene glycol diacetate, then sequentially adding bromocresol green, aluminum hydroxide and sodium alginate, stirring for 1 hour, grinding by a three-roll grinder until the fineness measured by a scraper blade fineness meter is less than 20 micrometers, and thus obtaining the ink, wherein the ink is changed from yellow to blue-green.
The foregoing is only a preferred embodiment of this invention and all equivalent changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
