[Person Interview] Hello, I'm Du Chuan.

The sudden attack of the new crown pneumonia has disrupted the pace of our lives, and "People Interview" has not met with you for a long time, and today the editor invited Mr. Du Chuan, who is busy in the fight against the epidemic.

Mr. Du Chuan is the executive deputy director of the Institute of Micro-nano Technology of Table Interface (hereinafter referred to as "Table Interface") and the general manager of Tianjin Qingke Environmental Protection Technology Co., Ltd. (hereinafter referred to as "Qingke Environmental Protection"), so most of us have already known him, but please follow this issue of "People Interview" to learn more about this teacher who is willing to try all kinds of new things.

 

Hello, Mr. Du Chuan. Thank you very much for being a guest in our "People Interview". Although many friends have already known you, please introduce yourself first.

My hometown is Dongying, Shandong Province, which is located at the mouth of the Yellow River. I lived here until I went to college. The university studied in the School of Mechanical Engineering of the University of Science and Technology Beijing. After graduation, he was sent to Tsinghua University to directly attack the doctoral degree. The postdoctoral degree was also completed at Tsinghua University.

So what is the course from the beginning of the table interface to Qingke Environmental Protection to the present Cai Hui?

I started my doctoral research in 2009, and the project was basically completed in 2014. Later, I went to a central enterprise for an internship. The high-end hospital was established in 2014. After its establishment, Mr. Wang suggested me to work in the high-end hospital. He thought it was more suitable for me. After on-the-spot investigation and understanding the future development plan of the high-end hospital, I was moved and gave up my job at that time and came to the hospital. Our idea at that time was to set up a table interface research institute in a high-end institute to industrialize while doing research and development.

In the second half of 2014, we were already working on self-assembly coating technology. After finding an investor in Tianjin in the first half of 2015, the company was established in July of the same year. It was actually a difficult period from the establishment of the factory to the start of production in November. I just graduated and had no experience in production. At that time, the company's investors gave a lot of support. In 2016, the company officially started external sales. At that time, the environmental protection industry was very hot, but the competition was fierce. We found that filter materials alone could not form a very favorable market competition, and the profit margin was not high. Therefore, in the second half of the year, we adjusted the business direction and began to develop environmental protection equipment and engineering based on core filter materials. In this way, we achieved rapid development in 2016-2018. In 2017, we were prepared for danger in times of peace and felt that the smog would soon be solved, and the industrial environmental protection market had a downward trend. Therefore, we began to develop a series of environmental protection products for civilian use, and we also had a series of products of the following Cai Hui brand.

Can you describe the development model of this part of the table interface?

According to our exploration experience, if the research institute wants to achieve good development, it needs to meet two conditions: one is to be able to get support from large projects, or to carry out R & D cooperation with some large enterprises, so as to ensure that the team's funds are in a relatively stable state; the other is to form technologies and products that can be accepted by the market as soon as possible on the basis of early R & D funds, Industrialization by itself or cooperation with large-scale enterprises in the industry, form a stable product income. By solving the funding problem, the Institute can gradually grow according to its own technical characteristics.

Now the table interface mainly focuses on research and development and testing, and interfaces with the company's product department and production department, responsible for the research and development and testing of the technical part of the product, as well as the development and landing of the production process in the process of industrialization.

We can also see that Cai Hui is doing a good job in marketing now. Do you have any plans or arrangements for Cai Hui's marketing in the future?

Cai Hui is part of Qingke Environmental Protection. The company has two divisions, B- end and C- end. The B- end division mainly focuses on filtering materials and equipment, and is mainly engaged in industrial waste gas and wastewater treatment. The C- end division is the Cai Hui division, which currently focuses on aldehyde removal, odor removal and disinfection. At present, Cai Hui has settled in Jingdong, Taobao, Tmall, Netease's strict selection, Xiaomi's products and some distinctive e-commerce platforms. A stable sales channel has been formed online and offline agents are also being developed.

"Material wisdom, light up life" is our slogan, so the future development direction of Cai Hui is to apply advanced material technology and coating technology to civilian products. At this stage, efforts are still being made to increase the market share of aldehyde removal, odor removal and disinfection products.

It seems that the current plan is steady and solid, consolidate the foundation.

Yes, there will not be too many categories expanded in a short period of time, and the three categories of aldehyde removal, odor removal and disinfection supplies are the main ones.

Last year, Cai Hui was also the United Matrix Power, and jointly launched the "Excellent Sports Plan" with Olympic champion Wu Minxia. What work will be carried out in this regard this year?

The "Excellent Sports Plan" consists of five directions: clothing, food, housing, beauty and pet. At present, the two sides have set up a joint venture company in Tianjin. At this stage, they mainly carry out offline services such as indoor formaldehyde purification, disinfection and sterilization, anti-skid and self-cleaning in combination with the direction of "living. The company's products and service standards are mature in this area, but will be slightly delayed by the outbreak.

Now with the improvement of the quality of life requirements, the demand in this area should also be gradually increasing.

Yes, especially in cities with higher consumption levels, the more significant demand growth.

One of the biggest things this year is the new coronary pneumonia epidemic, in fact, many of us have no way to participate in the front line of the fight against the epidemic, can do very limited things to fight the epidemic. But we understand that you were involved in the research and development of the fight against the epidemic on the second day of the new year, can you tell us the story and feelings of fighting the epidemic on the battlefield of scientific research?

In fact, we have already reserved this technology before. The original plan of air purification gel was to go on sale in April this year. Due to the outbreak of the epidemic after the Spring Festival, the product was launched ahead of schedule.

This really confirms the saying that "opportunities are reserved for those who are prepared.

There were already some reports of new coronary pneumonia before the Spring Festival, but it didn't feel that serious at the time, but we also thought about it and thought the market for germ-free products in 2020 should be good. Then there was the first day of the Lunar New Year at around 10 pm when Mr. Wang contacted me and asked if there were any technologies or products that could be used in the treatment of new coronary pneumonia. I immediately thought that the air purification gel could be used. I sorted out the relevant information and sent it to Mr. Wang for feedback to the school that night. The next day, on the second day of the new year, the working group was pulled up, and the people from the research institute and the company were all in the group. At that time, it was already decided to do this, and it was to do its best to speed up and hurry up.

At the beginning of the research and development of air purification gel, it was designed with the scheme of aldehyde removal as the main and bacteria removal as the auxiliary, so the first problem to be solved is the formula adjustment. On the evening of the third grade, a preliminary plan was discussed, but a new problem followed: testing. At that time, the third and fourth days of junior high school were the most tense times. Everyone was in a state of closed doors, and the R & D personnel were also in their respective homes. However, our team is still very powerful. In the early morning of the 4th, the company assistant drove directly to the home of her colleague Ding Chunli (the research and development personnel in charge of this product in the early days) in Cangzhou, Hebei Province. After picking up her, she went to the supplier in the next county to pick up the bottle, arrived at the research institute at noon, started the production in the afternoon, and filled the first batch of air purification gel in the evening. The first batch of samples were sent to Tsinghua Chang Gung Memorial Hospital for preliminary trial.

It seems that our product road is also very tortuous.

It's really more tortuous. At that time, roads were closed in many places, and the cars that picked up people and things could only drive to the end of the road, and they had to send products to the hospital during the most stressful period. The risks and everyone's psychological pressure were still quite high. After the first batch of products were filled, we were faced with the problem of shortage of raw materials. At that time, basically all the drug manufacturers were in full production, so the raw material supply and logistics of chlorine dioxide were very tight. Later, on the 7th of the month, we finally found the raw materials and took another logistics vehicle before arriving in Tianjin. On the eighth day of the month, people from all departments of the research institute and the company came and set up the first temporary production line for production. The more than 10000 bottles of air purification gel initially produced were all donated to Wuhan, Tsinghua Chang Gung Memorial Hospital and Beijing Railway Administration and other regions and institutions in urgent need of disinfection materials. We can say it is the second day of the junior high school online, the fourth day of the junior high school offline, and the eighth day of the junior high school.

Through this incident, we can see that the cohesion of our team is still very good.

Yes, the cohesion of the team is good. The work during this period of the epidemic has led to a significant improvement and transformation of the team as a whole, and this experience has been of great help to the growth of the team.

After the eighth day of the month, various employees have been added to the production line one after another. Whether it is the company's design, sales, photography or accounting, they all do production work, because the most important thing at that time was production. At the same time, everyone worked together to solve many problems, one of which was traffic. At that time, there were some public transportation, but in order to ensure the safety of employees, we were not allowed to take it. All those who could drive first picked up other colleagues in the morning and then came to work together at the research institute. In spite of this, everyone can guarantee to arrive before 8: 30, which shows everyone's enthusiasm for this matter.

Participating in this matter can be said to have three meanings: first, to do a little bit to fight the epidemic; second, to allow good technology to be industrialized; and third, enterprises create both social and economic value. Now it can be said that everyone involved feels very honored.

At that time, this kind of active participation should also be under great pressure.

Everyone is nervous and stressed. I am also under great pressure, and the sources of pressure are various, but the most worrying thing is the problem of personnel infection. During that period, we also fully did a good job in disinfection, protection, temperature measurement, etc., and did everything possible to ensure the safety of employees. Although there was a lot of pressure at the time, everyone was firmly doing it, because we all believed that this was the right thing, then other things could be compromised in front of what everyone thought was right.

Although we are not on the front line of medical treatment, each of our participants is not an anti-epidemic fighter and hopes that the epidemic will pass as soon as possible.

After this incident, are there any plans to add some medical-related products?

The medical field is a very large market, many leading enterprises are gathered in the medical sector, it is not easy to enter. However, the air purification gel has gradually formed some influence. In the later period, efforts will be made to expand the product series of air purification gel and upgrade the product iteration. In the near future, we plan to launch a gel-based disinfection robot, which is mainly used in shopping malls, railway stations and other places with high traffic.

Very much looking forward to it.Although I can often see you in the courtyard, I seldom see your sports figure. Do you usually have any favorite sports?

Table tennis and basketball are fine. They play a lot when they go to school, and then they run. It is OK to run 400 meters, which belongs to the level that can represent the "expedition" of the class, and it is less often that it can represent the departments.

As a body test 50 meters unqualified Xiaobian expressed great admiration.During the Chinese New Year, I am busy with the air purification gel. How can I balance it here?

My family is very supportive. My lover works in Beijing and is also engaged in work related to the transformation of university achievements, so I can understand it many times.

Do you have any plans for the family in the near future?

Both of them hope to do a good job in their career before thinking about their life and family plans.
