It has been two months since the COVID-19 epidemic tested the people of China. At present, the epidemic has basically been effectively controlled. In the face of the epidemic, I have seen the strength of the motherland and the greatness of the people. I saw courage, tenacity, dedication, optimism and the power of unity. In the face of great disaster, we let the world see what China people are! ! ! Write this post and record this unforgettable time. Carry forward the spirit of optimism and write a limerick! ? Masks have become a luxury, and dinner has become a serial. The road became a racing track and the hotel became a storage room. ? The food market has become a new attraction, and the queue has become a landscape. Hand washing has become a compulsory course, and haircut has become a long-standing problem. ? Angels in white is the most respectable and the forefront of retrograde danger. Find yourself useful, and stay at home and make contributions. ? A new experience of live broadcast and online teaching of gerontology. Never mind whether you like it or not, just stay honest and don't fill in the blanks.

most people were caught off guard by the sudden epidemic. Because the supply of protective masks was in short supply, they became luxury goods, and their limited inventory was quickly exhausted, and masks obtained from various channels were also varied. Draw a roaring dog on the mask to vent your emotions on boring days, and you can only entertain yourself at home.

The family has a large population, and it has been one and a half months since the 29th of the twelfth lunar month. Because of my perseverance in food, the dinner is unambiguous. When I put the photos together, I find that many dishes will appear repeatedly, which seems to be a "continuous look".

In the past, the bustling traffic suddenly disappeared, and the empty road became a racing track. Due to the need of prevention and control, dinners in public places were banned. The dining peak in the first month of each year did not arrive as scheduled, and restaurants were almost closed. Many restaurants became storage rooms for ingredients.

It's almost the only outdoor activity to buy necessities with a mask. Visiting the vegetable market is like traveling. Although the epidemic situation is severe, there is no looting in the market. Orderly queuing has become a manifestation of social civilization. I believe we will live more confidently and calmly after the epidemic.

Washing hands frequently is an effective means to stop the spread of virus, and it is also a good hygiene habit. Because of the risk of infection caused by the narrow indoor space, the barber shop basically closed down, and the ordinary service of haircut became a problem. In the outdoor at MINUS 15 degrees in the north, it is an imaginable sour and refreshing to have an open-air haircut!

We may have been biased against angels in white in the past, but at present, they put their lives between us and the virus. The picture on the left is the work of students, and young people gradually understand this era.

I know a little about the medical situation in foreign countries, and we should have some happiness living in China now. The picture on the left is the work of students, and young people gradually understand this era.

Pay tribute to the medical workers. You are retrograde in times of crisis and the most lovely people in people's hearts. The picture on the left is the work of students, and young people gradually understand this era.

The dream of staying at home and doing nothing for many years came true too suddenly. Not adding burden to the society means contributing to the country. In my spare time, I studied the recycling method of masks (which will be explained in detail later).

In order to stop classes and study, the course of 133 people needs to be broadcast live on the Internet. After purchasing the necessary equipment, BLACKPINK will appear. Different from other network anchors, we need to carefully prepare lessons and check on attendance.

There is no point in grandstanding the epidemic at present. We in Qi Xin work together and are not afraid of the test. Only when it is difficult can we win the final victory!

In order to study the regeneration method, we disassembled the mask and studied its detailed structure. A common protective mask consists of a structural layer of non-woven fabric on the outer layer, an adsorption filter layer of meltblown fabric on the middle layer, and a contact layer of non-woven fabric or gauze on the inner layer. The key to recycling is not to destroy the functional layer of meltblown cloth in the middle under the premise of disinfection.

The following is the mask regeneration scheme that I have developed in combination with my major. Put a bracket in the steamer, and choose the support method with the least contact with the mask as much as possible.

place the outside of the mask upward on the bracket.

when the steamer is opened, the temperature is adjusted to 111℃, and the time is adjusted to 12 minutes. The high-temperature steam can kill bacteria and viruses, and has the functions of restoring medium gaps and deodorizing. The steam at 111℃ will not damage the filter layer of the mask, and the general mask will not lose its protective effect after being regenerated for about 5 times.

after steaming, open the door and take it out when the steam is exhausted.

put the steamed mask on a clothes rack to dry for one day, and the treated mask can be reused.

the way to verify whether the regenerated mask has protective ability is very simple: inject water into the core area of the mask.

It is enough to ensure no leakage that the protective function of the mask is not affected during the regeneration process. Of course, this kind of water injection test has a negative impact on the number of times the mask is recycled. Once again, this regeneration method is limited to the use of masks.

The time of staying at home is coming to an end, and I feel that I have gained a lot. Fake disinfection expert, lame network anchor and amateur baking master are all new titles, and they are almost refined. We will never forget this difficult day when we face the test, which will be our memories in the future!
