Tang Yilin, Chairman of Shengquan: “The Corner” meets “Graphene”

In Tang Yilin's view, enterprises and scientists do different research in the laboratory. Scientists pursue theoretical rigor, one is one, two is two; enterprises should be practical, whether it is single layer or 10 layers or 30 The multi-layered "biomass graphene composite carbon material" is an improvement if it can improve the quality of life of people or improve the function of existing products.
During the "two sessions" this year, Premier Li Keqiang participated in the deliberation of the Shandong delegation. Tang Yilin, chairman of the Shengquan Group, as the deputy to the National People's Congress, reported that his company had produced graphene and also produced graphene consumer goods such as clothing and heating. And so on.
When he heard that the source of graphene produced by Shengquan was corn cob, Premier Li Keqiang was very interested to say: "If you can make new breakthroughs in corn processing, the state will fully support it!" The Prime Minister further pointed out that this is not only It will reduce financial pressure and increase the income of farmers.
When Premier Li Keqiang left, Tang Yilin deliberately went to the front to add clothing with graphene raw materials to the Prime Minister. The Prime Minister joked: "This is very expensive!"

"Unicorn" encounters "ceiling"
Listening to Tang Yilin's story about the development of graphene-related products in Shengquan is quite a coincidence. In 2008, Shengquan furan resin has achieved the world's first, phenolic resin is also the first in Asia, and there is not much room for further development of resin. In the deep processing of corn cob, there is also a semi-finished product called cellulose. One of the topics he met when he met professors from the Chinese Academy of Sciences and Tsinghua University was to help Shengquan find a project to improve the use of cellulose. As time went by, Tang Yilin heard many suggestions from the project but was always dissatisfied. He had a stalk in his heart. "Is there the most advanced?"
In 2013, a professor at the Chinese Academy of Sciences accidentally said that an Indian student had written a paper. Any leaves collected and burned to ash could be made into graphene. The professor said that your cellulose is more pure than the leaves. !
Previously, Tang Yilin had contacted a Spanish company, which happened to be the first company in the world to produce graphene. He had talked about the possibility of adding graphene to the resin of Shengquan, and learned about what graphene is all about. What makes Tang Yilin deeply impressed is that foreign businessmen told him that graphene is 2,000 yuan, even if it is produced in large quantities, it costs 200 yuan and 1 gram. Now listening to the professor said that the corn cob can extract graphene and make up the decision to go on this project.
Since the development of ceramic filters by Shengquan in the eight years of anti-Japanese war, Tang Yilin realized that the road of self-development is long and full of uncertainty. When he is working on a new project, he can develop it himself, otherwise he can buy it.
In the 1990s, Tang Yilin visited a British company and saw that the company produced a material for filtering molten steel. When asked, it was known as a ceramic filter. Tang Yilin had a thin and semi-finished product. At the beginning, Tang Yilin didn't care too much. Later, when the British company went public, he was shocked when he saw the prospectus. The ceramic filter sold for 1 cubic centimeter and sold for RMB 0.7-0.8, and the global net profit of 200 million euros. There are 100 million euros. Therefore, he made up his mind to invite domestic experts to carry out "reverse research". The mainland could not solve the problem and went to Taiwan and South Korea to find someone. It took eight years and it was not until 2004 that the trial was successful. In the meantime, it is not enough to be able to find a foothold and find a clue. But after the success, the benefits are amazing. Today, ceramic filters contribute nearly half of the profits to Shengquan every year.
In fact, Shengquan has had an indissoluble bond with “technology transfer” from the beginning. Shengquan Group was formerly known as Qizhen Furfural Plant, and was a workshop of Jinan Chemical Plant. It was one of the first batch of aid projects in the former Soviet Union. The Cultural Revolution moved to Zhangqiu Town in the late period. The leading product furfural was furan resin. raw material. Tang Yilin said: "The project that was originally aided to China was to make furan resin. The project was withdrawn before the experts broke the Sino-Soviet relationship."
In 1985, when Tang Yilin pondered the furan resin, he happened to meet two engineers from Beijing Environmental Protection System to find a company to transfer this technology. "At that time, the engineer did not have the awareness of making money. The transfer fee of 50,000 yuan was to open a results appraisal meeting. It also helped you train the workers for a month." Recalling the scene, Tang Yilin was embarrassed. It is also this technology transfer that opened the door to the unicorn of this segment of the industry.
Furan resin is widely used in the casting sanding process, that is, after the “reform and opening”, with the rapid expansion of the domestic market, the output of Shengquan has also increased at a rate that doubles every year. Tang Yilin said: "At that time, the workshop was just covered, the production capacity could not be supplied, and then the workshop and equipment were needed. It was like this for four or five years."
The achievement of the position of the leader of the Shengquan industry stems from two aspects. First, Shengquan mastered a core technology for producing sterols from furfural, and the cost was greatly reduced. When other companies lose money because of price wars, Shengquan can still make profits; the other is the development of additional measurement tools. Tang Yilin introduced: "I went to Japan at the time and saw that Japan is promoting a curing agent to be added to the instrument. Because the resin needs to be added with a curing agent to cure, the curing agent is very troublesome because of seasonal changes and temperature changes. The invention of this kind of instrument is used in winter, one is used in summer, and adjusted by proportional relationship, called 'A+B automatic joining instrument'. After returning, we will immediately develop and develop, and after successful, quickly promote it among the national customers. If you use the resin of Shengquan, you will be provided with equipment and services for free, but within five years, the same price must be given priority to purchase Shengquan products, and five years is enough to get all the national markets."

Practical is king
Tang Yilin began to extract graphene with cellulose under the guidance of professors of the Chinese Academy of Sciences. But after half a year of testing, the content is always up.
Tang Yilin said that at the beginning, fortunately, there was a "furnace" for testing satellite insulation materials, and the temperature could be increased to the required degree, otherwise the pre-cost would not be known.
Originally, the "Shenzhou spacecraft" returnable satellite reclaimed cabin needs to be filled with heat-resistant, cold-cold, stable and non-combustible insulation materials. This material was imported from abroad. In order to ensure the localization rate, the military department found the Shengquan trial system.
Tang Yilin said: "We have specially entered a set of equipment, including the 'furnace' for testing, but after the equipment came in, the Feitian project was suspended for 2 years, and our equipment came in handy."
Try to try, the extracted graphene content is always less than 1%. At this time, Tang Yilin searched online and saw that a research group at Heilongjiang University claimed that straw extraction of graphene could achieve 98%. Although it is not necessarily so high, it should be able to extract more graphene.
Tang Yilin immediately contacted the research team and provided 10 batches of cellulose. The subsequent test reports were very satisfactory, all of which were above 98%. Tang Yilin immediately made a decision to transfer this technology to Shengquan! The other party naturally agrees. Soon, on June 11, 2014, the two parties signed an agreement to complete the relevant procedures for technology transfer.
The other party said that you have to do at least another 2 years of trials. Tang Yilin said that it is impossible, what we want is to quickly push to the market.
The test was compressed to completion in 2 months, followed by the construction of the production line.
Before seeing Tang Yilin, the reporter first visited the Graphene Research Institute of Shengquan Group. The R&D engineer said: "In fact, when we go to school, we use a pencil to draw a piece of paper on the paper, that is, graphene."
From the expert's point of view, it is not difficult to accidentally prepare a little graphene. It is difficult to industrially prepare a graphene with a stable single-layer structure. The so-called standard graphene refers to a stable structure in a single-layer atomic arrangement. It turns out that graphene has a "catch-up" effect like the magnetic powder of the magnet, and it is difficult to maintain a single-layer structure in a natural state. Some experts have compared the single-layer graphene to the sky captain marshal. After the "group suction", the multi-layered graphene is the pig's ring that falls into the human world, and returns to the original shape and returns to graphite. This is why it is called “Bio-based nano-carbon materials collaborative innovation application research and development center” in cooperation with Heilongjiang University, and there is no direct use of the term graphene.
According to the engineer, the patented technology purchased from Heilongjiang University only completed the “small test”, and the Shengquan engineers themselves went on the “pilot test” and realized mass production. At present, 15 tons of corncob produces 1 ton of graphene. There are two kinds of products, one kind of powdered graphene. It is a dispersant added to graphene and is uniformly dispersed. It has 2 layers, but more is 3-10. The other layer is a liquid state.
In fact, there is currently no company in the world that realizes mass production of pure graphene industrialization.
In August of that year, Shengquan Group announced that “the preparation of biomass graphene by the 'group coordination method' jointly developed by the team of Changjiang Scholars of Heilongjiang University was declared successful”. The test results show that “the number of layers is less than 10 layers”, and the conclusion is that “the performance is comparable to that of similar products produced from graphite.”
In 2015, Shengquan has built a graphene production line with an annual output of 100 tons. At the same time, it has developed a variety of consumer products including clothing, electric heating plates and other graphene components.
In the face of the interview, Tang Yilin tells the truth. Although the production line is said to be 100 tons, the actual production may be only half. The reason is that the production line is very long, the raw materials are thrown into the feed port, and the product is produced five days later. In other words, there are still many areas where the production process needs to be improved.
Tang Yilin is more concerned with the use of graphene elements to develop civilian products, such as clothing, home mattresses, pillows and electric heating panels.
The electric heating plate from Shengquan can achieve the effect of 800 watts of ordinary electric heater with 300 watts of power. At the same time, because it can be made very thin, it can be made into a picture hanging on the wall.
Tang Yilin introduced that the graphene actually added to the clothing should be more accurately called “biomass graphene composite carbon material”. The magic is that only the "biomass graphene composite carbon material" extracted from straw and corn cob has the health function of far infrared.
He said that in order to get high-purity graphene, it took a lot of effort and cost a lot, but the problem of making clothes found that the far-infrared function became weak. It took a long time to understand that pure graphene has almost no far infrared function.
It turns out that this "biomass graphene composite carbon material" extracted from straw and corn cob contains a trace of metal compounds and non-metallic compounds. It is an impurity from the perspective of extracting graphene, but it is added to cotton yarn. After being dressed, the wavelength is measured between 4-16um, and this band is called the "wave of life."
Tang Yilin said: "Achieving an emissivity of over 88% can be called a far-infrared function. After we add 'biomass graphene composite carbon material', the emissivity of clothes is 91%-92%. Our group's top executives try on this kind of clothes. My feeling is very comfortable. In theory, the far-infrared of this band has many benefits for people."
In Tang Yilin's view, enterprises and scientists do different research in the laboratory. Scientists pursue theoretical rigor, one is one, two is two; enterprises should be practical, whether it is single layer or 10 layers or 30 The multi-layered "biomass graphene composite carbon material" is an improvement if it can improve the quality of life of people or improve the function of existing products.
Graphene cotton socks produced by Shengquan have a deodorizing function. But unfortunately, due to the high manufacturing cost, a pair of graphene cotton socks are currently sold for nearly three hundred yuan on Tmall.
Tang Yilin said that mass production will definitely lower the price. The China Development Bank has provided a 100 million yuan interest-free loan for the construction of a graphene production line with an annual output of 1,000 tons. He revealed that in September or in a few months, Shengquan will produce a "graphene-like clothing like a steel wire" without washing. In theory, buying one can always wear it.
