Practitioner of Green Chemistry

 ——Remember Li Guopei, Chairman of Shenzhen Kangfeng Company

He was a good science and technology worker.

Mr. Li Guopei graduated from the Department of Mechanical Engineering of South China University of Technology with metallurgical heat treatment. He was employed in a large state-owned enterprise in Shenyang in the 1970s. Soon after he joined the company, he solved several technical problems that have not been solved for many years. Then he was assigned the responsibility in the second year. The domestic and leading "250 kg iron core power frequency induction furnace" and large-scale "silicon controlled electro-polishing equipment" overall and electrical design and a successful test, received a lot of media reports. In the early 1980s, he worked at the Hangzhou Institute of Mechanical Science. During his tenure, he had a number of award-winning achievements. He was appointed by the Zhejiang Provincial Commodity Inspection Bureau as the Chinese technology leader to negotiate with foreign parties on the technical problems arising from the introduction of equipment by a key state-owned enterprise in Hangzhou. The success forced the foreign party to make compensation.

He was also an excellent entrepreneur. His independent research and development products were once favored by domestic and foreign professional recognition and customers.

Mr. Li Guopei went south to Shenzhen in 1988 and founded his own curtain wall door and window company. The company's wave-lifting sliding door won the first place in the best engineering product at the 2006 San Francisco Building Materials Expo; in 2007, the American door and window magazine "Window & Door" 》Wave lifting sliding door was rated as "the most innovative door" and won the crystal medal. In 2010, five iconic buildings in Phoenix Island, Hainan, which received much attention at home and abroad, were discussed with PK of more than a dozen domestic and foreign companies, and finally chose Mr. Li Lao's wave lifting sliding door design.

However, in 2012, Mr. Li Lao unfortunately failed to invest, and his entire net worth disappeared in an instant. When this man was nearly ancient, the blow was conceivable. However, Mr. Li did not retreat in a hurry. Instead, he continued to pay attention to the things he was interested in with a calm mind, hoping that he would have the opportunity to exert his expertise and contribute to society in his later years.

With his obsession with investigating air pollution, he resolutely devoted himself to the research of air purification technology in his rare years.

In recent years, several relatives and friends of Mr. Li's health and well-being have passed away one after another, and the cause of the disease is more or less related to air pollution, which makes Mr. Li lamented. In December 2011, the US embassy released PM2.5 data, which caused an uproar, and the harm of PM2.5 was so great? Air pollution is already so serious? This old science and technology worker who still maintains his childhood curiosity and is accustomed to finding out about unknown things has developed a keen interest in indoor air pollution control, and has begun research and pre-development.

Everything started from scratch, and he had no money. Fortunately, with the support of friends and family, he quickly gathered funds for research and development. In early 2013, Shenzhen Kangfeng Environmental Technology Development Co., Ltd. was officially established.

Last year, Shanghai conducted a random inspection of 22 air purifier brands. Only Sweden’s Bruyal and U.S. Amway were qualified, and the national brand was completely wiped out. This made Mr. Li Lao very excited. He secretly determined that he must establish a leading purifier nation. Brand. Mr. Li has purchased many famous purifiers from Europe, Japan and Hong Kong, and found that these machines cannot effectively remove formaldehyde. So he started to research and develop on the basis of the fourth generation of air purification technology, but found that the removal of formaldehyde is basically ineffective when the ambient humidity is high, and Mr. Li is determined to overcome this difficulty.

 

He, a practitioner of green chemistry, has overcome world problems in one fell swoop!

The removal of low-concentration free formaldehyde at room temperature has always been a worldwide problem. Mr. Li Lao tried all the existing technologies and found no solution, only to find another way. After reading a lot of information, Mr. Li found that some domestic and foreign scholars have proposed the concept of using green chemistry and advanced oxidation technology to purify air pollutants, but due to various technical problems, it has not been able to do so.

Mr. Li has accumulated a lot of knowledge and rich experience. After more than 600 days and nights and more than 2,000 experiments in the environmental cabin, he has found changes from the details and rules from the failure. Finally, he has successfully developed a new Air purification technology, this new technology can not only remove formaldehyde almost 100%, but also has an excellent effect on the removal of particulate matter and bacterial viruses in the air. The technology has three major highlights:

1) Overcame the worldwide problem of "removing low-concentration free formaldehyde at room temperature"

2) For the first time, advanced oxidation technology has been successfully applied to the field of indoor air purification, which can convert pollutants in indoor air into harmless or less harmful compounds to purify the air fundamentally.

3) Regardless of whether it is in China or abroad, the advanced oxidation technology used for gas previously required a high voltage and strong electric field, and the new technology does not need to use this high energy consumption, high cost, and large volume method, it can be easily achieved.

Mr. Li insists on taking green chemistry as the principle and direction of technical research, that is, the chemical process does not produce pollution and eliminates pollution from the source. The air purification technology he developed achieved the goal of green chemistry well, turning a new page in green chemistry.

 

Today, he has made a comeback with the world's most advanced air purifier and completed his gorgeous turn.

After repeated verification of the purification effect of the new technology, Mr. Li Lao upgraded the engineering prototype three times, and finally launched the first generation of Kangfeng air purifier: KF-501A in May this year. After testing by authoritative departments, KF-501A has created three world firsts:

l The world's first formaldehyde removal at room temperature (30m3 environmental cabin)

Formaldehyde clean air volume CADR 341m3/h

Formaldehyde removal rate 99.9%/h

l The world's first air sterilization (30m3 environmental cabin)

Sterilization rate 20min 99.68%

30min 99.99% 17cfu/m3

60min >99.99% <7cfu/m3

l No. 1 in purification energy efficiency in the world

Energy efficiency of formaldehyde purification>13m3/w·h

Particulate purification energy efficiency>20m3/w·h

All are calculated according to the 1st (minimum) air volume effect

These data are also unmatched compared with the current IQAir (gc), the world's best purifier brand. Not only that, KF-501A is far superior to IQAir (gc) in terms of energy saving, service life, and price.

The 71-year-old man used his wisdom and unremitting spirit to bring epoch-making technological inventions, and confirmed the advancement and true effectiveness of the technology with his products. For the first time to solve air safety and respiratory health problems for human beings, it provides a comprehensive, efficient, reliable and low-cost solution with extraordinary social significance and extremely broad market prospects.

We are admired by Mr. Li’s professionalism, and his perseverance to practice the principles of green chemistry has moved us even more. As a sparse old man, Mr. Li, through his own efforts, has realized the sublimation of the value of life and made great contributions to human health.

Glossary:

Green chemistry is at the forefront of today's international chemical science research. It draws on the latest theories and technologies of contemporary physics, biology, materials, information and other disciplines, and is an emerging interdisciplinary with clear scientific goals and social needs. From a scientific point of view, green chemistry is an update of the basic content of chemical science; from an environmental point of view, it eliminates environmental pollution from the source; from an economic point of view, it uses resources and energy reasonably, reduces production costs, and meets Requirements for sustainable economic development.

Advanced oxidation technology refers to the production of hydroxyl radicals (•OH) and a series of •OH chain reactions to attack organic pollutants in water and degrade them into water, carbon dioxide and inorganic salts.

Hydroxyl radical (•OH) is a natural substance for purifying pollutants. It is a strong oxidant. It has a strong function of purifying pollutants formed by humans and can remove pollutants in the lower atmosphere. And convert it into harmless or less harmful compounds, play a purification role, help to rebuild the stratospheric ozone layer, can remove NOX, SO2, NH4 and other harmful substances in the atmosphere. Hydroxyl radicals can fundamentally solve the problem of environmental pollution and achieve zero environmental pollution and zero waste discharge.
