Liu Min was stunned when he heard Liang 18 say "sprinkle quicklime on the horse circle, of course, there are other disinfection and sterilization methods"; He thought in his heart: "It seems that Grandpa Liang is an expert, he may know a lot of disinfection and sterilization methods; It's better to take the opportunity to communicate with him and learn! ”

After thinking about it in his heart, he smiled and took a few steps closer to Liang Eighteen and said, "Grandpa Liang, you are the horse trainer of the horse farm; You must know a lot about disinfection and sterilization; The little woman wanted to ask what measures should we take before we enter the cell compound! ”

Liu Min's words can be described as a pun, she said that she wanted to learn from Liang 18; But there is no element of questioning in the discourse.

Because at this time, there was still a smell of blood floating in the wind on the side of the prison compound, which was the result of the brave fight between Wu Ding, Zheng Shuang, Wang Xiang and the soldiers led by Wei Baimao, Ma One-eyed, An Xinglong, and Yang Baras.

Liu Min judged from the smell of blood in the breeze that there were corpses in the courtyard of the cell; But the corpses could not be Wu Ding, Zheng Shuang, and Wang Xiang.

Liu Min knew that the three of Wuding had kung fu, and people with kung fu generally had more stamina than those without kung fu; Even if you are slashed a few times, you will not necessarily die if you are stabbed and stabbed unconscious.

And what Zhou Xing said about Wu Ding, Zheng Shuang, and Wang Xiang being hacked and stabbed to death by Wei Baimao and Ma One-eyed is just a superficial phenomenon.

In this sense, the corpses placed in the courtyard of the cell must have been brought by An Xinglong and Yang Baras.

For this reason, Liu Min and Liang 18 can grind and communicate here.

Liang 18 listened to Liu Min's words, "What measures should we take before entering the prison compound", and said bluntly: "Of course, we have to carry out disinfection and sterilization!" ”

After Liang Shibai said this, he paused and cleared his throat and said, "Lao Yu was in a hurry to go over to see the situation at the scene just now to see what kind of disinfection method is the best; Now that we have smelled blood, we must protect ourselves first; Get some old vinegar fumigation and disinfection, and then rescue Wuding, Zheng Shuang, and Wang Xiang! ”

Liang 18 said, looking at the four girls of Hongyun, Luxing, Lanmei, and Baixue, and said, "You four work hard, get a few things to cover your nose and mouth as soon as possible!" ”

Liang 18 admired Liu Min very much when he said that he used old vinegar to fumigate, and listened to him Hongyun and the four girls talk about getting a few things to cover their noses and mouths; Isn't this the mask of the future?

Liu Min thought about it like this, so he pulled out a yellow silk handkerchief from his body and folded it into a mask style and said: "Grandpa Liang is talking about masks, so do it!" ”

Liu Min said, and quickly made a mask and said to Hongyun, Green Apricot, Lanmei, and Bai Xue: "The four sisters will do it according to the style of Minzi, one for each of the six of us!" ”

The four of Hongyun did it according to Liu Min's folding, and Liu Min looked at Liang 18 and said, "Did Grandpa Liang use the old vinegar fumigation method to disinfect the stables before?" ”

"That's right, Lao Yu used old vinegar to disinfect the stables of the horse farm, and the effect is quite good!" Liang Shibai said confidently, and said: "Miss Min is a god, I don't know if the old vinegar fumigation method proposed by the old decay will work!" ”

"Okay! Grandpa Liang had used the old vinegar fumigation method to disinfect the stables before, and now the disinfection effect of using it in the yard of the cell should be said to be no problem! Liu Min said in admiration, shook his two thumbs up and down and said approvingly: "Grandpa Liang is the medicine fairy Sun Simiao, Minzi has met the true god today!" ”

Liang 18 laughed and said, "Miss Minzi is old!" The old decay can be the true god, and the sun has not come out of the west yet! ”

Liang 18 said very humbly, brushing the goatee on his chin and said: "Old decay is not a true god, but he still knows a little about sterilization and disinfection!" ”

Liu Min laughed and said: "It seems that the little woman has underestimated Grandpa Liang before, if Grandpa Liang has no scruples; Then tell the younger generation what you know about sterilization and disinfection! ”

Liang 18 was not pretentious when he heard Liu Min say this, and raised his arm and said impassionedly: "The ancestor of the old decay is a langzhong, and the old decay has known that realgar has anti-virus effects since he was a child; Take a large piece of realgar from the paulownia and burn it in the fire to smoke the foot bandage, grass shoes, and leaders, which can prevent the spread of epidemic bacteria through clothing! Frying with astragalus, Chuanxiong, and angelica in a large pot can prevent and kill viruses inside and outside the room; Humans and animals are not infected with diseases! Of course, you can also use quinoa, tiger head, realgar, podophyllum, Tianxiong, honey locust, turnip and other medicines to grind into honey pills as big as soap cores, and burning a pill on the bed can prevent the plague! ”

Liang 18 paused as he spoke, cleared his throat and said, "Treat the trauma, spray some wine, and then use a torch knife to burn red and then cut the rotten flesh; Or boiling water can prevent germ infection; There are also peppercorns and salt water used to disinfect and dig meat to heal wounds; Hua Tuo in the Three Kingdoms did just that! ”

Liu Min was dumbfounded, the anti-virus sterilization method that Liang 18 talked about is the originator of various disinfectants in later generations!

Liu Min is a medical doctor and knows that there are 9 main types of disinfectants commonly used in later generations according to their ingredients:

1 chlorine-containing disinfectant, 2 peroxide disinfectant, 3 aldehyde disinfectant, 4 alcohol disinfectant, 5 iodine-containing disinfectant, 6 phenol disinfectant, 7 ethylene oxide, 8 biguanide disinfectant, 9 quaternary ammonium salt disinfectant.

If it is classified according to the disinfection effect, there are three types: one is a high-efficiency disinfectant, the second is a medium-efficiency disinfectant, and the third is a low-efficiency disinfectant.

The chemical disinfection and sterilization methods commonly used in later generations are generally as follows:

(1) Immersion method. Choose a disinfectant with a wide sterilization spectrum, weak corrosiveness, and water-soluble disinfectant, and immerse the items in the disinfectant to achieve the purpose of disinfection and sterilization at a standard concentration and time.

(2) Wipe method. Choose a disinfectant that is easily soluble in water and has strong penetration, wipe the surface of the article, and achieve the purpose of disinfection and sterilization in the standard concentration and time.

(3) Fumigation method. Heating or adding an oxidant to make the disinfectant gaseous; Achieve the purpose of disinfection and sterilization in the standard concentration and time.

The fumigation method is suitable for indoor disinfection of items and air, or delicate and valuable instruments and items that cannot be steamed, boiled, or soaked - such as blood pressure monitors, stethoscopes, and tickets used by people with infectious diseases.

The fumigation method can also be refined into: 1. Pure lactic acid fumigation. It is often used for air disinfection in operating rooms and patient rooms. Add 12ml of lactic acid and the same amount of water to every 100m2 space, put it in the treatment bowl and close the doors and windows, heat and fumigate to remove the heat source after evaporation, continue to close for 2 hours, and then open the window for ventilation.

2. Vinegar fumigation. 5-10ml/m3 heat water for 1-2m3, heat and fumigate with closed doors until the vinegar evaporates.

Because vinegar contains 5% acetic acid, it can change the acid-base environment of bacteria and have antibacterial effect, and the air in the room of influenza and encephalopathy can be disinfected.

3. Formaldehyde or peracetic acid can be used for fumigation and sterilization.

4. Spray method. With the help of ordinary sprayers or aerosol sprayers, the disinfectant produces particulate aerosols to disperse in the space to disinfect the air and the surface of items.

For example, if 1% bleaching powder clarifier or 0.2% peracetic acid solution is used as air spray, spray 8ml of 2% peracetic acid solution per cubic meter on the surface contaminated by bacterial spores for 30 minutes, and at room temperature above 18 °C) can achieve a killing rate of 99.9%......
