  Since the outbreak of the new crown virus, the majestic power of the people across the country has been aroused and aroused under the strong leadership of the party. In this "epidemic" without gunpowder, scientific protection and bravely shoulder the responsibility of stopping the epidemic. Judging from the constantly announced changes in key indicators, the "epidemic" of the national war has entered a state of stalemate and confrontation.

  In a critical period, how to dispel the people's panic about the epidemic is as important as taking good protection. From the initial airborne transmission, to droplet transmission, contact transmission, to oral and fecal transmission, and aerosol transmission, the fear of the new coronavirus is not only because there is no specific medicine, but also because of the "unpreventable" transmission route. In fact, "aerosol" is not a mystery. A few years ago, a company called Kangfeng Environmental Technology launched an air purifier aimed at purifying "aerosol", and it became a key product purchased by many hospitals in the following years. , Its core material "AOP-KF solid caustic soda" has also become an important accessory purchased by many air purifier manufacturers. Nowadays, both academician Zhong Nanshan and medical experts recommend that qualified families turn on air purifiers or fresh air equipment, but in purifying "aerosol", not all products can effectively deal with it, and master the core of "aerosol" elimination. The healthy wind of technology and materials has been deeply cultivated in this field for many years.

FOR "AEROSOL", HOW EFFECTIVE IS THE AIR PURIFIER?

  When the public's panic about the spread of "aerosol" spread on social media, the reporter contacted Li Haiyong, general manager of Shenzhen Kangfeng Environmental Technology Development Co., Ltd. At this time, he had no time to take into account the interviews of various media, and he was still busy donating medical supplies to areas and hospitals with severe epidemics. Especially after "aerosol propagation" is well-known to the public, more and more companies purchase Kangfeng air purifiers and purchase Kangfeng's core filter material "AOP-KF solid alkali". Although production has resumed on the third day of the lunar new year, air purifiers, masks and core filter materials (AOP-KF solid alkali) are still unable to meet the needs from all sides.

  However, Li Haiyong patiently explained the past and present of "aerosol" to reporters. Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. Aerosol propagation means that droplets mix in the air to form aerosols and float to a distance, causing long-distance propagation. At present, the fifth edition of the National Health Commission's diagnosis and treatment guidelines pointed out that aerosol transmission has yet to be clarified. However, from the perspective of all parties, under certain special conditions, aerosol transmission does exist. The spread of the virus Infection is a virus that requires a certain dose and remains active to cause illness. Therefore, the risk of long-distance aerosol transmission is lower than short-distance droplet transmission and direct contact transmission. He said that there is no need to panic about "aerosols," but be vigilant.

  So is the air purifier useful? There is no doubt about this. Otherwise, major air purifier manufacturers would not be able to quickly donate air purification equipment to areas and hospitals with severe epidemics. According to the information released by the Chinese Center for Disease Control and Prevention, the size of the new coronavirus is about 100 nanometers, which is similar to the size of H1N1 virus (the size of H1N1 virus is 80-120 nanometers), and it spreads through saliva, dust and other carriers. , And these carriers are generally larger than 5 microns. The mid-to-high-end air purifiers have adopted H13 and H14 high-efficiency HEPA filters, and the filtration efficiency of 0.3 micron particles can reach more than 99.97%. But it should also be pointed out that most air purifiers on the market are aimed at haze and formaldehyde, rather than purifying "aerosols". They may not be efficient enough to purify bacteria and viruses. If there are no better materials for dispelling "aerosols" , Its filter is also easy to cause secondary pollution.

TO PURIFY "AEROSOL", WE MUST MASTER THE CORE TECHNOLOGY

  In the years when most "competents" paid attention to the purification of haze and formaldehyde, Kangfeng Environmental Technology has long taken the removal of "bacterial virus aerosol" as the main technical direction. At the end of 2019, at a seminar themed "Bio-Aerosol Annihilator-Air Purifying Appliances in Preventing Respiratory Diseases Caused by Air Biological Pollution" hosted by China Household Electrical Appliances Research Institute, Li Haiyong explained AOP to the industry -The mature application of KF solid alkali biological cleansing technology in the removal of biological aerosols.

  It is understood that AOP-KF solid base is a micro-nano, green advanced catalytic oxidation material. With its strong oxidizing property, it can destroy the microbial enzyme system, and has a strong killing effect on bacteria, fungi, and viruses. It has a small dosage, It has the characteristics of fast action and no secondary pollution. The Kangfeng KJ900F-H01 air purifier with this technology as the core has a good effect of removing microorganisms. This technology can be prepared into particles of different sizes according to different application scenarios and used in different purification systems or equipment. At present, in addition to being used in civilian air purifiers, it is also used in the "100-level" clean wards of more than 300 tertiary hospitals, which breaks the monopoly of foreign equipment in this segment.

AOP-KF® SOLID BASE

  Speaking of "AOP-KF solid base", its inventor is Li Haiyong's father, Li Guopei, chairman of Shenzhen Kangfeng Environmental Technology Co., Ltd. If there is no such epidemic, everyone will probably not attach so much importance to the bacteria and viruses in the air. But Li Guopei, who comes from a medical family, is different. In 2015, when he developed the air purifier, he paid great attention to the sterilization rate and virus inactivation of the air purifier. He said that South Korea suffered from MERS virus with a mortality rate of 30% in 2014. As there is no experience similar to China's SARS (SARS), South Korea suffered a great loss. The culprit of the raging avian flu and the outbreak of large-scale influenza is the pathogenic microorganisms in the air. Their existence is not only the fuse for the outbreak of various diseases, but also serious hospital cross-infection. Therefore, Li Guopei led the team to develop the "AOP-KF solid alkali". Its products become "passive disinfection as the primary and active disinfection as the secondary" during the purification process, which can effectively kill viruses and bacteria in the air through catalytic oxidation reactions. During the reaction, about 0.03ppm of chlorine dioxide will be released. The World Health Organization (WHO) lists chlorine dioxide as an A1 level safe and efficient disinfectant, which can kill all bacterial propagules, viruses, fungi and their spores, etc. And after a lot of research, it has been determined that the concentration of chlorine dioxide in the air is less than 0.1 ppm, which has no effect on human health.

2016 RESPIRATORY HEALTH AND SAFETY FORUM

  Kangfeng started to pay attention to "aerosol" very early. In 2016, Kangfeng hosted a "2016 Respiratory Health and Safety Forum" in Beijing, and officially launched the first medical air disinfection and purification machine YKJ2000F-A01 and YKJ1000F-A01 to the market. Li Guopei's emphasis on and research in the field of "aerosol" has also been recognized by the scientific community. In June 2017, Li Guopei was invited to attend the 600th Xiangshan Science Conference with the theme of "Bioaerosols and Human Health, National Biosafety and Air Pollution", and discussed with all the biologists, environmental scientists and other professionals present In view of the various diseases that can be caused by bioaerosol respiration exposure, this conference has also been hailed as a "milestone" in the promotion of bioaerosol development in Chinese academia. Subsequently, Kangfeng responded to the call of the conference to promote the industrialization of related aerosol technology, and it has been recognized and purchased by more hospitals. But in the consumer market, it is still a niche brand. But the sudden outbreak of the epidemic brought Kang Feng to the front of the stage. Li Haiyong said, "AOP-KF solid caustic soda" is currently supplied to a number of "air purification" companies in addition to its own use.

DONATE WITH ALL YOUR STRENGTH, SMALL BUSINESSES SHOW GREAT RESPONSIBILITY

 The movie "Spiderman" has this sentence: "The greater the ability, the greater the responsibility." Compared with companies that donate more than 100 million yuan at every turn, Kangfeng is a small company. However, Li Haiyong knows that the masks and air purifiers produced by the company with "AOP-KF solid alkali" as its core technology are helpful to this epidemic. Therefore, before the large-scale outbreak of the epidemic, the company gradually initiated donations. Li Haiyong said that we learned from various sources that "Wuhan pneumonia" is not simple, and may even have "human-to-human transmission", so we immediately donated 6,000 yuan worth of "Kangfeng anti-influenza anti-infection masks" to the Shenzhen Municipal Health Commission. "500 masks to ensure the respiratory safety of front-line government workers responding to the epidemic.

  Afterwards, Kangfeng joined hands with caring people and companies to donate masks and air disinfection and purification equipment to major first-line hospitals, including Wuhan University People’s Hospital, Guangzhou Eighth People’s Hospital, Shanxi Medical University First Hospital, Sun Yat-Sen University Fifth Hospital, etc. Many patients sent thanks after receiving the masks.

  Kangfeng anti-influenza anti-infection masks are different from mainstream products on the market. Even N95 only blocks the spread of viruses, bacteria and aerosols in the air, but cannot kill pathogenic microorganisms attached to the masks. Therefore, if you come into contact with the virus attached to the mask while wearing a mask, the virus will transfer and continue to spread to cause infection. In addition, the collection and disposal of discarded masks has become a problem, which is likely to cause secondary pollution. Due to the use of AOP-KF® solid alkali, Kangfeng's anti-flu and anti-infection masks, such as viruses attached to the mask, will be oxidized and killed after contact with the solid alkali, and its replication will be blocked to avoid secondary pollution. The trace amount of chlorine dioxide released at the same time will enter the human body and kill the virus in the body. It is a safe and efficient new method of anti-virus. According to Li Haiyong, AOP-KF® solid base is also effective against the new coronavirus, because this strong oxidizing effect is to coagulate and denature the virus capsid protein to achieve the purpose of inhibiting its survival and killing it, which can effectively combat all Pathogenic microorganisms. After the outbreak, the Shenzhen Party Secretary Wang Weizhong Dai Kang are put in the front-line experts and exchange epidemic wind antiviral anti-infection masks.抗病毒防感染口罩。

  In addition to masks, the air purifiers produced by Kangfeng also come in handy. With the development of the epidemic, Kangfeng successively donated 81 air disinfection and purifiers worth 710,000 yuan to Shanxi Medical University, Wuhan University People's Hospital, and Union Hospital of Tongji Medical College of Huazhong University of Science and Technology. It is worth mentioning that, under the initiative of the Guangdong Indoor Environmental Sanitation Industry Association, Shenzhen Kangfengxiang donated 20 Kangfeng No. 1 KJ520F-H01 air purifiers with antibacterial and antiviral functions and Kangfeng No. 1 Pro KJ900F to Huanggang, Hubei. -20 sets of H01 air purifiers, worth nearly 270,000 yuan.

  Li Haiyong said that as a niche brand in the market segment, we have done nothing but a meager effort. As the factory's production capacity continues to increase, 2,400 Kangfeng anti-influenza and anti-infection masks will also be donated to Longgang District Hospital and Shenzhen Third People's Hospital to support front-line workers. In order to respond to market demand, Kangfeng is still actively looking for a suitable mask production line, and plans to put into production three types of masks, butterfly, boat and flat.

FROM BEHIND THE SCENES TO THE FRONT DESK, KANGFENG PRODUCTS ARE LIKED BY USERS

  "Although we have not been able to fight on the front line like "white angels", since the announcement of the new crown virus epidemic, Shenzhen Kangfeng has employees staying on duty throughout the Spring Festival holiday to deliver the equipment needed in various places on standby." – Li Haiyong said

  Colleagues , heads of the company and sales and technical support departments actively contact first-line hospitals and government departments to respond to the epidemic, hoping to obtain qualification approval and production support to provide society with more epidemic prevention materials; the procurement department continues to communicate with supply companies to ensure production capacity. The whole company is working hard to expand production capacity and provide more epidemic prevention materials.

  In addition to the company's full operation, Li Guopei's behavior during the Spring Festival is even more touching. As everyone knows, the susceptible population of the new crown virus this time is the elderly, but the 76-year-old Li Guopei went to the front line and rushed to Guangzhou, Zhuhai, Shenzhen and other major designated new crown virus confirmed patients to be admitted to hospitals. On the one hand, he comes from a medical family with excellent daily maintenance and excellent physical fitness. On the other hand, Li Guopei is also well aware of the seriousness of the epidemic, and every time he goes to the front line, he uses Kangfeng products to protect him. In the past ten days, in addition to donating masks and air purifiers, he has deeply understood the progress of the epidemic and communicated with medical staff, explaining how to use Kangfeng's technology to prevent the epidemic and introduce the use of related products. It is worth mentioning that he also sent these protective products to hospitalized patients. For Li Guopei, this kind of personal charity is not the first time. Prior to this, he gave air purifiers to many patients with respiratory diseases to help them alleviate the suffering caused by the patients. And this time, there were also patients who were lucky to "turn negative" because they used Kangfeng's products.

LI GUOPEI WENT TO THE FRONT LINE TO EXPLAIN THE EFFECTS OF MASKS AND HOW TO USE THEM TO MEDICAL STAFF

  Li Guopei hopes to pass on Kangfeng's products and technologies to help those patients alleviate their pain and help hospitals and individuals to protect themselves. In addition to the hands-on approach, Kangfeng also cooperated with the Shenzhen University School of Medicine to apply for the "New Coronavirus Infection Emergency Prevention and Control" special project of the Shenzhen Science and Technology Innovation Commission to contribute scientific research to the prevention and control of the new coronavirus. In addition to cutting in with technology and products, Shenzhen Kangfeng and the American Association of Hundreds jointly organized a special assistance fund for Hubei named after Professor Tian Changlin, and was responsible for the implementation of the fund in Hubei. One of the representatives of the air purifier arranged to go to the designated treatment point for patients with new coronavirus infection in Guangzhou to evaluate its applicability in the nosocomial infection prevention and control environment.

  With the improvement of Guangdong Province’s scientific and technological prevention and control capabilities in response to the novel coronavirus infection, Shenzhen Kangfeng has started to cooperate with Guangzhou Eighth Hospital to apply for provincial science and technology on the basis of participating in the provincial science and technology department’s scientific and technological emergency project for preventing and controlling novel coronavirus infection. The "New Coronavirus Infection Prevention and Control Technology and Product Project" of the Office is expected to be able to form emergency and useful technologies and plans in about three months. With the industry's attention to aerosols, "air purification" and material manufacturers such as Kangfeng Environmental Technology, which focus on purifying viruses and bacteria, will also usher in a new wave of market demand. For Li Guopei, years of perseverance will also usher in wider recognition and attention.
