Information

Droplets spread at close range

The main mode of transmission of the new coronavirus is the transmission of close droplets, which are well understood, mainly by sneezing, coughing, spitting, etc., and these droplets contain the virus, once inhaled by others, it will lead to infection, this transmission is the main way.

Many people become infected through this route of transmission.

Contact transmission

Contact transmission is also well understood, where droplets accumulate on objects or bodies and are then touched by someone else's hand, then come into contact with someone else's mouth, nose, eyes, etc., causing these people to become infected, such as handrails, elevator buttons, and the person's own hands.

This route of transmission also leads to infection in many people.

Aerosol propagation

Aerosol transmission is one of the ways of the latest findings, mainly is someone infected when buy vegetables, contact with patients in just 15 seconds but infected, patients and infected people were wearing masks, also have no direct contact, by analysis, later should be aerosols lead to the spread of infection, the so-called aerosol droplets is mixed to form in the air of jelly, and then are absorbed by others, leading to infection, this is very dangerous.

Some cities have been scrambling to prevent it by air disinfection.

Wear a mask when you go out and replace it

For personal prevention, it is necessary to wear a mask when going out. You can choose a medical surgical mask or N95. The mask should be used correctly, with light color inside, dark color outside and metal strip on.

Wash hands frequently to ensure hand hygiene

Also need to wash hands frequently, wash hands need to use soap or antiseptic hand sanitizer, so as to avoid contact with infection, especially in contact with the handrail, press the button of the elevator and so on, it is necessary to wash hands in time, before wearing masks also need to wash hands, this we do not forget.

Keep distance from others

Due to the way of aerosol transmission, individuals in the prevention of need to pay special attention to the distance with others, generally the best control of 1.5 meters above, to ensure adequate safety distance, and if you meet people without masks, it is best to leave in time, do not contact, so as to better prevent the infection of new crown pneumonia.

Difference between calcium hypochlorite and bleaching powder
Difference between calcium hypochlorite and bleaching powder
1. What is Calcium hypochlorite? The main components of bleaching powder commonly used in aquaculture are calcium chloride and calcium hypochlorite. Among them: the effective component of bleaching powder that plays a role in disinfection is calcium hypochlorite [ca (CLO) 2], and calcium chloride is a chemical substance that will obviously absorb moisture. Due to the existence of calcium chloride in bleaching powder, the available chlorine in bleaching powder is easily affected and reduced. Because calcium hypochlorite is the essence of bleaching powder, calcium hypochlorite is also called bleaching powder essence in the market. Compared with bleaching powder, it is pure calcium hypochlorite essence and does not contain calcium chloride and other hygroscopic substances. The chlorine content is about 68%, which is significantly higher than the effective chlorine content of the newly produced non damped bleaching powder. Generally, the disinfection dose is only 0.1~0.2ppm. In aquaculture and other industries that need disinfection and oxidation, disinfectants that dissolve in water and produce hypochlorite are generally referred to as chlorine containing disinfectants. The germicidal efficacy of chlorine containing disinfectants is closely related to the amount of effective chlorine they contain. The higher the effective chlorine, the stronger the disinfection and oxidation capacity. 2. Comparison of advantages and disadvantages between bleaching powder and calcium hypochlorite Advantages of bleach: It is cheap and has obvious effect on general pathogenic microorganisms. Disadvantages of bleach: Due to the strong water absorption of calcium chloride contained in bleaching powder, it is easy to decompose when exposed to light, water, heat, etc., and is not resistant to storage. Especially in humid areas, the available chlorine of bleaching powder will decrease exponentially in about a month. Even lead to the loss of proper disinfection effect. The principle of bleaching powder deterioration: Calcium chloride in bleaching powder absorbs water and makes calcium hypochlorite in bleaching powder generate hypochlorite.   3. Hypochlorous acid will decompose into hydrogen chloride and oxygen under light conditions, thus losing effective chlorine. Advantages of calcium hypochlorite: contains very little hygroscopic calcium chloride, so calcium hypochlorite is relatively stable and resistant to storage and transportation (which is very important to ensure the disinfection effect). Compared with bleaching powder, the available chlorine of calcium hypochlorite is stable and high, which has obvious effect on general pathogenic microorganisms. The amount of use in disinfection is small, which reduces the amount of labor. Disadvantages of calcium hypochlorite: Since calcium hypochlorite contains a large amount of effective chlorine, protective measures need to be taken during operation.

Calcium hypochlorite is a white, concentrated chemical sold as a powder, as crystals and in tablets. All are used to disinfect and sanitize drinking water and swimming pool water. When combined with water, calcium hypochlorite releases oxygen and a high concentration of chlorine molecules. Chlorine is an effective way to kill bacterial and fungal populations in water sources, and, compared with other sources of chlorine for water purification, it is easier and safer to use. However, there are some downsides to be aware of in calcium hypochlorite use. Cost Effectiveness One of the primary benefits of calcium hypochlorite is that a relatively small amount of the chemical can successfully disinfect large amounts of water, making it one of the most cost-effective choices in water sanitation. According to Survivaltopics.com, a site devoted to providing readers information about surviving outdoors and during emergency situations, a 1-lb. bag of calcium hypochlorite in granular form can treat up to 10,000 gallons of water. Ease of Use Although using chlorine as a water disinfectant is generally simple and efficient, calcium hypochlorite is preferred over the other common forms of chlorine water treatment–chlorine gas and liquid bleach (also known as sodium hypochlorite)–because it is more stable, requires less equipment to use and is easier to transport. Chlorine gas is highly effective but must be handled with extreme care because of its hazardous, corrosive nature. Liquid bleach is most useful when treating only small amounts of water. By contrast, calcium hypochlorite is safer to handle than chlorine gas and can be used on much larger volumes of water than bleach. Length of Storage Another benefit of calcium hypochlorite is that it can be stored for long periods of time without any of its disinfectant ability diminishing. Other forms of chlorine, such as liquid bleach, degrade in a matter of months. In order to be certain that your bleach has the optimal level of chlorine, a representative of Clorox says, you should change your supply of bleach every three months.
