How to effectively disinfect your phone

With the popularity of the Internet, the development of mobile terminals. The emergence of smart phones allows everyone to operate everything with a single phone. People are becoming increasingly dependent on mobile phones. Think of how much time we spend with mobile phones every day, and the state of not leaving the hand must be a portrait of many people. But have you ever wondered how many bacteria there are in a mobile phone that can't be separated? It may become a huge hidden danger to our health.
The bacterial content on the surface of the mobile phone is as high as 120,000 / c㎡, which is 18 times the bacterial content of the toilet handle. Various germs and viruses are hidden in it。
First let's take a look at our most commonly used disinfection method-alcohol alcohol disinfection. Can it really disinfect?
The main component of alcohol is ethanol. Too high concentration of alcohol will form a protective film on the surface of the bacteria, preventing alcohol from entering the bacteria, and it is difficult to completely kill the bacteria. If the alcohol concentration is too low, although alcohol can enter the bacteria, it can not solidify the protein in the body, nor can it completely kill the bacteria; therefore, the 95% and 75% alcohols commonly bought in drug stores are generally the former. For cleaning, for example, delicate objects such as mobile phone interfaces that cannot be washed with water, the latter is used for disinfection.
In fact, alcohol disinfection is mainly because the ethanol in alcohol can enter the surface of the lipid layer (ie, the fat layer) of bacteria, so that the protein can be coagulated to achieve the disinfection effect, such as herpes simplex virus, hepatitis B virus, human immunodeficiency virus and so on. But some viruses don't have adipose tissue, so alcohol is not effective. Spores and enteroviruses
It takes 30 seconds to kill E. coli with 70% alcohol, 5 minutes to Staphylococcus aureus, and 1 minute to Pseudomonas aeruginosa. However, the long-term disinfection effect cannot be guaranteed because ethanol is volatile.
Then, let ’s take a look at a friend mentioned: UV disinfection, that is, deep UV LED disinfection.
Ultraviolet light is actually very common. It is light with a wavelength of 10 to 400 nanometers (nm) in sunlight. It can be divided into UVA, UVB, and UVC according to different wavelength bands. The UVC band has a bactericidal effect, but! UVC in sunlight is blocked by the ozone layer and cannot be used by people. Therefore, people have tried every means to create an artificial "sunlight"-LED deep ultraviolet.
The sterilization principle of the deep ultraviolet LED disinfection technology is that the deep ultraviolet light generated by the LED penetrates the cell membrane and nucleus of the organism, directly destroys DNA, kills bacteria, and has a sterilization rate of up to 99.9%. And it does not produce ozone, no mercury, and no chemical additives. Some studies have found that no bacteria that can resist ultraviolet rays have been found on the earth, which is great!
At present, the artificial LED deep ultraviolet technology has been slowly applied to daily life, such as LED sterilizers on the market. It has a series of related products, including a mobile phone disinfection belt. It is about the same size as the mobile phone case we used before. It is portable and has LED disinfection lamp beads. It can be disinfected in 59 seconds.


Compact and lightweight, it can be carried around and disinfect you phone and other stuff at any time.
LED disinfection technology was first used for water disinfection of space stations, and it is still a difficult application technology worldwide. Let's try it out.

How to select to phone case that is fit for you

We don’t pay the insurance for our phone, but we will add some extra protection for it ， a phone case is one of the protection for your phone .So what case should we select for our smartphone ?

Let's stop plastic waste at its sources

  Around the world, one million plastic drinking bottles are purchased every minute, while up to 5 trillion single-use plastic bags are used worldwide every year. In total, half of all plastic produced is designed to be used only once — and then thrown away.While plastic has many valuable uses, we have become addicted to single-use or disposable plastic — with severe environmental consequences.  We have seen a lot of positive action to reduce the plastic waste such as: garbage sorting,limit the use of disposable plastic products and the developing and manufacturing of the recycling. But we need to do more, we need to stop the plastic pollution at its sources   100% Biodegradable material was tested is 100% compostable and  can be completely degraded into  carbon dioxide and Oxygen in the Under natural composting and home composting conditions . As a kind of natural degradable material, biodegradable material plays a unique role in environmental protection. Its research and development
