Problems solved by technology

Compared with the incineration method, the overall investment of the non-incineration method is lower. However, the disposal range is relatively narrow, and the amount is not reduced. Secondary transfer is required, and the disinfection is likely to be incomplete. The crushing requirements for medical waste are higher.
The incineration method has the advantages of large investment, thorough disinfection, volume reduction of not less than 90%, and land saving. However, the disposal of incineration tail gas is more complicated and difficult, especially the dioxin produced is not easy to control, and medical waste is disinfected. After liquid treatment, the bacteria in the waste can be killed, so that it can be reused, which is a breakthrough in environmental protection technology
[0003] Most of the existing disinfectants are sterilized with traditional Chinese medicine, the sterilizing effect is not good, the stability is poor, and it is difficult to continue to sterilize. Therefore, the present invention provides a disinfectant for infectious medical waste and its preparation method

Embodiment 1

[0026] A kind of infectious medical waste disinfectant of the present embodiment comprises the raw material of following weight portion:

[0027] 55 parts of modified nano zinc oxide, 15 parts of sodium camphorsulfonate, 10 parts of antibacterial stabilizer, 3 parts of hydrogen peroxide, 20 parts of deionized water;

[0028] The preparation method of described antibacterial stabilizer is:

[0029] Step 1: Hydrotalcite modification: crush the hydrotalcite into particles with a particle size of 1mm, put it in a water bath at a temperature of 70°C for 11 minutes, and then send it to a calciner for calcination, with a temperature increase of 1.5°C / min Raise the temperature to 150°C, hold for 10 minutes, then anneal to 90°C, continue to hold for 15 minutes, and finally cool down to room temperature naturally;

[0030] Step 2: Antibacterial hydrotalcite: Add hydrotalcite to the fungicide and stir at a speed of 100r / min for 20 minutes, then add starch additives, and then continue st...

[0040] 65 parts of modified nano zinc oxide, 25 parts of sodium camphorsulfonate, 20 parts of antibacterial stabilizer, 5 parts of hydrogen peroxide, 30 parts of deionized water;

[0041] The preparation method of described antibacterial stabilizer is:

[0042] Step 1: Hydrotalcite modification: crush the hydrotalcite into granules with a particle size of 2 mm, put it in a water bath at 80°C for 13 minutes, and then send it into a calciner for calcination, with a heating rate of 2.5°C / min Raise the temperature to 158°C, hold for 20 minutes, then anneal to 110°C, continue to hold for 25 minutes, and finally cool down to room temperature naturally;

[0043] Step 2: Antibacterial hydrotalcite: Add hydrotalcite to the fungicide and stir at a speed of 200r / min for 30 minutes, then add starch additives, and then continue stirring for 25 minutes....

Embodiment 3

[0052] A kind of infectious medical waste disinfectant of the present embodiment comprises the raw material of following weight portion:

[0053] 60 parts of modified nano zinc oxide, 20 parts of sodium camphorsulfonate, 15 parts of antibacterial stabilizer, 4 parts of hydrogen peroxide, 25 parts of deionized water;

[0054] The preparation method of described antibacterial stabilizer is:

[0055] Step 1: Hydrotalcite modification: crush the hydrotalcite into particles with a particle size of 1-2mm, put it in a water bath at a temperature of 75°C for 12 minutes, and then send it to a calciner for calcination at a rate of 2.0°C / min The heating rate is raised to 154°C, kept for 15 minutes, then annealed to 100°C, kept for 20 minutes, and finally cooled to room temperature naturally;

[0056] Step 2: Antibacterial hydrotalcite: Add hydrotalcite to the fungicide and stir at a speed of 150r / min for 25 minutes, then add starch additives, then continue stirring for 20 minutes, after...

Abstract

The invention provides an infectious medical waste disinfectant, comprising the following raw materials in parts by weight: 55-65 parts of modified nano-zinc oxide, 15-25 parts of sodium camphorsulfonate, 10-20 parts of antibacterial stabilizer, 3-3 parts of hydrogen peroxide 5 parts, 20-30 parts of deionized water; the preparation method of the antibacterial stabilizer is: step 1: hydrotalcite modification: the hydrotalcite is pulverized into a granular shape with a particle diameter of 1-2mm, and the insertion temperature is 70-80 React in a water bath at ℃ for 11‑13 minutes. In the modification, the nano-zinc oxide of the present invention first performs hot-pressing and calcining treatment on bentonite, and then performs activation heat treatment on nano-zinc oxide, and the sheet structure can be shrunk through the treatment of bentonite, thereby improving the bearing capacity of nano-zinc oxide , This is due to the shrinkage of the sheet, the decrease of the interstitial degree of the sheet, thereby shrinking and fixing the nano-zinc oxide, playing the role of fixing the nano-zinc oxide, and improving the antibacterial stability of the nano-zinc oxide.

Description

technical field [0001] The invention relates to the technical field of medical waste disinfection, in particular to a disinfectant solution for infectious medical waste and a preparation method thereof. Background technique [0002] There are two main types of medical waste disposal processes: non-incineration and incineration. Compared with the incineration method, the overall investment of the non-incineration method is lower. However, the disposal range is relatively narrow, and the amount is not reduced. Secondary transfer is required, and disinfection is likely to be incomplete, and the requirements for crushing medical waste are higher. The incineration method has the advantages of large investment, thorough disinfection, volume reduction of not less than 90%, and land saving. However, the disposal of incineration tail gas is more complicated and difficult, especially the dioxin produced is not easy to control, and medical waste is disinfected. After liquid treatment,...
