In the 5th China Innovation and Entrepreneurship Competition (Zhejiang Division) and the 3rd Zhejiang Torch Cup Innovation and Entrepreneurship Competition, the entrepreneurs of Jin Chengli rely on the fourth generation of atmospheric drying technology. The technology of mass production of aerogel materials stood out in the fierce competition and won the top 10 in the competition and won the award of the outstanding enterprise award. Three days later, he took the project to the finals in the Hangzhou Grand Zone of the Ningbo Hangzhou Bay New District International Entrepreneurship Innovation Competition.

It is understood that with the gradual deepening of "Popular Entrepreneurship and Innovation", Zhejiang, with its strong entrepreneurial genes, has a high level of entrepreneurial innovation and a high level of competition. The entrepreneurs who come to participate in the competition are no shortage of academicians of the Chinese Academy of Sciences, talents of returnees, and thousands. The planners, the top domestic experts, etc., the jury of many well-known investors and entrepreneurs are also professional and sharp. As an ordinary technology entrepreneur, what kind of magic does Jin Chengli have to conquer the judges of the two high-level competitions?

Aerogel, the magical material that changes the world

There is a material that is light as smoke, has a blue color under the light, and has a material that can withstand more than 1000 degrees of high temperature to care for delicate flowers. There is a material that can turn the explosive power of 1 kilogram of explosive into invisible. There is a material that can be used. Transformed into a "sponge baby" to absorb the leaked crude oil at sea, there is a material you can wear it to climb the snow-capped mountains and the fire is unscathed, there is a material that has set 15 Guinness records... This magical material is not a nightmare in science fiction, it has Come to our side, it is aerogel.

It is reported that aerogel is an ultra-light solid material with nano-porous structure, the porosity can be as high as 99.8%. Invented by American scientists in 1931, it has many magical properties in the fields of electricity, optics, acoustics, mechanics and heat. One of the top 10 most popular science and technology since the 1990s, it has been listed as a national strategic emerging industry, with dual application technology with great application value.

"This product is too imaginative. I think it can't be done for a lifetime." When it comes to aerogel, the gentle and elegant Jin Chengli immediately becomes passionate. "Aerogel has so many magical features, just As a revolutionary alternative to traditional insulation materials , there will be tens of billions of dollars in the market in the future. Now our domestic petrochemical, heat pipe network and other fields have been applied. We are now using high-speed rail, and the future clothing and shoes, There will be huge application prospects in the fields of building energy conservation ."

Yazhi Industrial Co., Ltd., committed to aerogel industrialization

The establishment of ASPEN, which has a close relationship with NASA in 2001, marks the beginning of a truly commercial aerogel industrialization. In 2004, the first aerogel enterprise in China was established and in 2006, the aerogel powder was successfully tested. Jin Chengli became the first person engaged in aerogel industrialization in China.

As a pioneer, there is hardly any industrialization experience that can be used for reference. After Jin Chengli led the technical team to experience thousands of trial failures, he finally achieved a major breakthrough in the aerogel “NHT drying molding” process, and realized the first aerogel product in China. Mass production breaks the monopoly of aerogel products by American companies. They then took the lead in developing a series of aerogel products such as aerogel felts, aerogel plates, aerogel shaped parts, and aerogel lighting plates.

After the batch production, due to the low awareness of the aerogel material market, in order to open the market as soon as possible, Jin Chengli turned to the marketing department and became a domestic gas field, high-speed rail, nuclear power, new energy vehicles, underground rescue capsules, thermal pipe network and many other gas condensation. Pioneer in the rubber application market.

At the end of 2014, with the continuous development of the aerogel industry, the domestic focus on energy conservation and environmental protection, the aerogel industry ushered in the window of industrial development, Jin Chengli resolutely resigned from a certain unit of the aerospace system serving at that time, established Zhejiang Shaoxing Shengnuo Energy Saving Technology Co., Ltd. developed a new type of aerogel industrialization technology and embarked on the road of entrepreneurial innovation.

Jin Chengli graduated from Southwest University of Science and Technology in Mianyang, Sichuan Province. He has a bachelor's degree and a master's degree. He has cultivated his character who is brave enough to take responsibility and is not afraid of challenges. Now he is committed to entrepreneurial innovation, and he has made remarkable achievements along the way. The results, in his own words, are "finally back to the beginning."

Cost and quality, one must not be less

Price is the biggest obstacle to the application of aerogel industry. Once the production cost of aerogel materials is significantly reduced, the market scale will expand rapidly, product sales will expand rapidly, and revolutionary replacement of traditional insulation materials. At the same time, aerogel materials are prone to dust during use and are a place where customers are eager to improve. Jin Chengli, who regards “improving the customer experience and continuously creating maximum value for customers” as the company's mission, has been working tirelessly to reduce costs and solve dust problems since the day of the company.

Tiandao rewards, by replacing expensive organic silicon raw materials with cheap water glass, replacing expensive supercritical high-pressure equipment with atmospheric equipment, and the new generation of atmospheric drying technology developed by Shenguo Energy Saving Technology Co., Ltd., the production cost and equipment investment are significantly reduced. It has strong competitiveness and properly solved the problem of aerogel dust, which laid a solid foundation for the company's future development.

Continuous automatic, breakthrough impossible

Some people are destined to love toss, perhaps Jin Chengli is such a person. After obtaining a major breakthrough in aerogel production cost and dust control, Shengnuo Energy has gained a significant technical advantage over its peers. This should be enough for the company to survive for some time, but Jin Chengli is not satisfied. “Now the production lines of all the manufacturers in our industry are intermittent semi-automatic production lines. No one is continuous and fully automatic, so it can't be done!” There is a bit of reluctance in the tone. From the high-tech products of aerospace, how can production methods stay in Industry 2.0 in the era of preparing to embrace Industry 4.0?

In fact, the traditional aerogel production technology is indeed difficult to achieve full automation: First, the production needs to use a large number of openable reaction kettles, through the driving of the entire roll of materials into and out of the reactor, Although the hoisting process is simple but difficult to operate fully automatically; the second is that the traditional production process does not match the time of each process, and the difference is very large. From a few minutes to ten hours or even a few days, it is impossible to operate the line.

Colleagues said that sometimes he saw him sitting in the morning and burying his head to check the information without saying anything. Sometimes he kept writing and drawing and then shredded and thrown away. Sometimes he suddenly ran to the lab and slammed twice. Just when everyone almost forgot the full automation, one day he suddenly said excitedly that I seemed to find a way. After a round of tests, first ten hours, then eight hours, then six hours, "Well, we can now prepare the aerogel quickly in less than six hours and complete the process. Our new production line will achieve one end. The feed was discharged at one end, and there was no manual assisted continuous automatic production in the middle.” The applause sounded and the madman won.

Jin Chengli, a tutor during the master's degree at Southwest University of Science and Technology, and Prof. Yi Facheng, deputy dean of the Sichuan Military-civilian Integration Research Institute, told reporters that "aerogels will achieve continuous automated production, which will be a milestone in the history of aerogel material production. Not only the efficiency will increase by 3-5 times, the product quality stability will be improved, the production safety level will be improved, and the labor remission will be reduced. The automatic production line will occupy less space and the traditional kettle body. The equipment is mainly used for the production of coils. The crawler-type automatic production line can be well compatible with the flexible production of various products such as coils, plates, films, powders and granules."

It is reported that around the fourth generation of atmospheric dry mass production technology, Jin Chengli team has applied for more than 30 invention patents, and also applied for a PCT international patent, which will gradually build a multi-level patent protection system to seize the commanding heights of the industry.

Innovate and start a new era

At the National Science and Technology Innovation Conference in 2016, General Secretary Xi Jinping emphasized the need to launch a powerful engine of technological innovation, so that this Chinese ship will continue to advance toward the world's strong science and technology, and continue to advance toward the great rejuvenation of the Chinese nation and toward a better future for mankind. go ahead. Earlier, Premier Li Keqiang also pointed out that in recent years, China's scientific and technological achievements have been constantly emerging, and it is in a period of quantitative change to qualitative change. We must pay more attention to the original innovation ability, promote the basic research and applied research, technology development and collaboration, and realize the original innovation and re-innovation, integration and innovation integration.

Aerogel is a new material for the application of a wide range of basic strategies. The Chinese aerogel industry started almost in sync with the world. With more than 10 years of hard work in the academic and business circles, the Chinese aerogel industry has become a world-class possibility. .
