In 2020, public health time broke out. For a time, masks, medical alcohol, 84 disinfectant, etc. were sold out. Strengthening anti-virus and disinfection measures has become an important means for individuals, families, enterprises and institutions to respond.
The necessity of disinfecting the surface of objects. Jiang Rongmeng, a member of the expert group of the National Health and Health Commission, reminded that the virus will quickly settle down after coming out of the human body, and may fall on objects, and people can contact the virus through their hands. The virus can survive for several hours on a smooth surface, and can survive for 1 day in an environment with suitable temperature and humidity, and it can be found to reach 5 days. Therefore, we must pay attention to the regular disinfection of the surface of the object.
As an environment for centralized office and consultation, the command center, especially in the event of a major emergency, the more frequent the exchange of personnel, which will increase the probability of virus transmission. During this period, more attention should be paid to the disinfection of the command center's display and control system.
Some command centers use LED small-pitch display screens. Can we disinfect them with disinfectant?
Is there a difference between the disinfection methods of COB and SMD two small pitch LED screens? Let's take a look at the COB small pitch LED screen first. COB can use the following two methods of disinfection:
First, the surface of the display screen can be directly wiped and disinfected with 75% high-concentration medical alcohol, which will not affect the reliability of the display screen;
Second, the surface of the display screen can be disinfected by spray disinfection with 84 disinfectant (after dilution according to the instructions), and it can be dried with a damp cloth after 10 minutes, which will not affect the reliability of the display screen.
This is decided by the packaging technology of COB small pitch LED screen. The COB display has no problems such as bare lamp legs, the surface is smooth and seamless, wear-resistant and easy to clean, and has excellent performances such as mildew, dust, moisture, corrosion, static, and bump resistance. The COB display screen can prevent the intrusion of water splashed from all directions, etc., which creates conditions for the direct use of alcohol, 84 disinfectant wiping and other spray disinfection methods. The surface of the COB display is easy to clean, which can effectively prevent the deposition of harmful substances such as saliva, aerosol, dust and so on. There is no need to turn off the screen during the disinfection process, coupled with its long service life, to ensure 24 hours of uninterrupted operation of the screen.
However, SMD small-pitch LED screens should be treated with caution. SMD technology does not have the "three-proof" function, the surface is uneven, it may be attached to saliva, aerosol, dust and other harmful substances, not only difficult to wipe directly, the use of (chlorine, bromine) 84 disinfectant, high-efficiency disinfection water, etc. also have great risk. For example, the widely used 84 disinfectant, the main component is sodium hypochlorite, sodium hypochlorite produced hypochlorous acid in the aqueous solution can decompose ecological oxygen, has a very strong oxidizing. If used improperly, it may cause corrosion to the SMD small-pitch LED display screen and its lamp beads with poor protection performance. Based on this, small-pitch LED upstream manufacturers have urgently informed SMD manufacturers to use these disinfectants carefully.
At present, many emergency command centers across the country have undertaken the important task of the joint defense and joint control center. The different types of LED small-pitch screens in the center are sterilized in an appropriate manner to ensure the healthy environment of the command center and the normal operation of the display system. We need to pay attention. In addition, the COB small-pitch LED screen also has the advantages of extremely low cumulative bad spot rate, which can effectively reduce the damage of blue light to the human eye, and is favored by more and more users, and the growth rate is far faster than SMD.
The weather in the south is cold and humid, the pores are tightened, and the blood circulation is not smooth, so it is difficult to show a healthy complexion. Therefore, it is of great benefit to have a moderate facial massage after washing your face every time. From top to bottom, spiral from inside to outside, massage the face for a few minutes can accelerate blood circulation, warm the skin, expand pores, discharge old epidermal cells, and restore ruddy and healthy facial skin. This method can also improve the skin's resistance to cold. When massaging, pay attention to the cleanness of hands and gentle manipulation.
Winter bath tips:
If you don't want to see your skin haggard and dry next spring, you'd better take active action this winter and take advantage of bathing "beauty body"!
Alternate hot water bath: a simple way to enjoy a sauna at home. Flush with hot water with a water temperature of about 40oC for 2 ~ 3 minutes to warm the body, and then flush with cold water with a water temperature of about 17oc for 2 ~ 3 minutes. If you feel that the temperature difference is too large and you are not used to it, you can make the cold water temperature a little higher at first. Flush the body with the above hot water and cold water alternately for five times, and finally flush the body with hot water to feel smooth and comfortable.
There is no doubt that getting up in the morning in winter is "reluctantly", and the body generally feels a little stiff. Using the morning bath to clear your mind and stimulate your muscles can inadvertently make your mind clear and cool and start a happy day. The shower is 20 ~ 30 cm away from the face. Gently rinse it with cold water for five or six minutes, which not only helps to clear your mind, but also makes it easier to put on makeup. Late bath can eliminate nerve and muscle fatigue. In order to avoid over stimulating the skin, the water temperature should be kept between 38 ~ 40 degrees. Proper use of puffs can promote blood circulation and remove dead skin.
There are four commandments for skin care in winter
In winter, when the cold wind blows and the weather is dry, it will make dry skin more likely to lose moisture unknowingly. In the process of skin care, avoid the following skin care procedures:
(1) Use strong degreasing cleanser: especially for dry skin, use mild cleanser or soap containing oil.
(2) Wash your face with hot water: hot water has strong degreasing power. Wash your face with hot water to wash away the skin oil. Water is easy to lose, and the skin is more dry and itchy.
(3) Indoor temperature is too high: when the indoor temperature is too high, the indoor relative humidity will drop, and the skin moisture is easy to lose.
(4) Dry body immediately after bathing: it is not suitable to dry your face and body with a towel after bathing. Take a bath in cold weather. When you leave warm water, everyone will quickly dry their body and put on clothes. However, to prevent skin dryness and itching, you should apply moisturizing oil and moisturizing lotion to keep moisture in the dry half of your body.
The doctor suggested that an Aroma Diffuser should be placed indoors, which can effectively and immediately solve the problem of indoor air drying, humidify the air and solve the problem of air drying.
