In recent years, with people paying more attention to health, medical air disinfection machine has been widely used in the medical field. Medical air disinfection machine is a kind of equipment specially used to disinfect indoor air, which is mainly used in workplaces such as medical institutions, food processing industries, electronics industries and so on that require high-standard aseptic environment. With the increasing number of medical air disinfection machine brands in the market, choosing a medical air disinfection machine with better cost performance has become a difficult problem for many consumers. In order to help you buy a high-quality medical air disinfection machine that suits you, I investigated various platforms and analyzed the data of several brands, and sorted out the following reasons for reference: after investigation, the price of Desen's medical air disinfection machine is 3, to 9,, which is mainly used in hospitals, and the sterilization rate of Desen's medical dynamic air disinfection machine is as high as 99.99%, which not only improves the air sterilization accuracy, The product experience has been further improved. At present, disinfection products, a medical air from Desen, has a relatively large medical supply in the market. < P > In today's era, it is very important to do a good job in hospital hygiene in any place, which makes the demand for sterilization more and more. Sterilization is the basis of health work, because it helps to keep the environment clean and healthy, but there are many sterilization methods. I will introduce three common sterilization methods: plasma sterilization, ultraviolet sterilization and ozone sterilization,
their differences and advantages and disadvantages
1. Plasma sterilization
Plasma sterilization is a method to kill bacteria by using harmful ions and free radicals generated by plasma. Plasma is a state of matter, which consists of positively charged gas or liquid particles and negatively charged electrons. Plasma can be generated by high voltage electric field or high temperature. Plasma sterilization is an efficient and fast sterilization method. Plasma can remove pathogens and pollutants in air, water and various surfaces, which is called "the fourth generation sterilization technology". Compared with other common sterilization methods, plasma sterilization does not need to use chemical bactericides and disinfectants, so it is more environmentally friendly and safe.
second, ultraviolet sterilization
ultraviolet sterilization is a sterilization method that uses ultraviolet radiation to kill bacteria. Ultraviolet is an electromagnetic wave, which is divided into three bands: A, B and C. The wavelength ranges are 32-4nm (ultraviolet A), 28-32nm (ultraviolet B) and 2-28nm (ultraviolet C) respectively. Ultraviolet c-band is used to kill microorganisms (including bacteria and viruses). Using ultraviolet sterilization technology can eliminate a large number of microorganisms indoors, thus reducing the risk of cross-infection. Ultraviolet sterilization method is often used for cleaning and disinfection in hospitals, laboratories, food factories and other places. Compared with other sterilization methods, ultraviolet sterilization will not leave harmful chemicals.
third, ozone sterilization
ozone sterilization is a method to kill bacteria by oxidation-reduction of ozone molecules. Ozone is called "smart oxygen", and its chemical formula is O3, which is a colored and smelly gas. Ozone is highly oxidizing. When it comes into contact with bacteria, it will destroy the chemical bonds on the surface of bacteria, which will lead to the death of bacteria. Compared with other common sterilization methods, ozone sterilization does not pollute the environment and does not need to use chemical disinfectants.
The above three sterilization methods have their own advantages and disadvantages. Plasma sterilization is an efficient and environmentally friendly method, but the equipment cost is relatively high; Ultraviolet sterilization is a relatively safe and rapid method, but it requires light to directly irradiate the surface of bacteria, and cannot irradiate bacteria far away from the light source; Ozone sterilization technology has advantages in flexibility, treatment efficiency and service life of equipment, but ozone is harmful to human body to some extent, so it is necessary to pay attention to safety issues when using it.
during sterilization operation, it is necessary to select the appropriate sterilization method according to the actual situation. At the same time, when using sterilization equipment, it is necessary to strictly abide by the operating rules and safety standards to ensure the safety and sterilization effect of the equipment.
