A few years ago, a movie called "Chinese Partner" was popular across the country。Nowadays, in the era of mass entrepreneurship and innovation, there are vivid stories of "Chinese partners" behind every entrepreneurial team。

Guan Junkai, the founder of Xiamen Jujia Technology Co., LTD., and Qin Mingli, the technical director, were originally brothers who slept in bunk beds in college。After graduating from Central South University， An introvert, Qin chose to pursue graduate studies，He later became a professor at the University of Science and Technology Beijing.Extroverted Guan Junkai is early into the social exercise，Have experienced the ups and downs of choosing a career and starting a business，And engaged in semiconductor electronics and electrical sales process，Met the same small appliance sales experience Shi Lei。The three people who were originally far apart, under the wind of the mass entrepreneurship and innovation policy, were linked together by a project called aluminum nitride and became a "partner" in business.。

On November 24, 2017, on the stage of the New Material industry finals of the Sixth China Innovation and Entrepreneurship Competition, which was filled with bright lights and experts, young Doctor Lu Huifeng, with the instructions of his mentor Qin Mingli and the entire entrepreneurial team, stepped on the highest stage of the national competition。"For many years, aluminum nitride raw materials have been monopolized by Japan, especially in the field of defense and military industry, and foreign countries have stepped up restrictions on supply to China.。We rely on the scientific research team of professor Qin Mingli of the University of Science and Technology Beijing, ten years of grinding a sword, and finally developed high-quality aluminum nitride powder and products that exceed the Japanese Tokusan standard, breaking the foreign monopoly in this field, and realizing that all aluminum nitride is not imported from abroad!In the end, the entrepreneurial team of Xiamen Juporcelain Technology Co., Ltd. was deeply moved by the judges present with the feelings of entrepreneurs who "dare to be the first in the world" and won the first prize of the start-up group of the New materials industry Finals of the sixth China Innovation and Entrepreneurship Competition。

He vowed to break Japan's material monopoly!

Aluminum nitride, the theoretical thermal conductivity is 7-10 times that of alumina, which is equivalent to copper and aluminum;The mechanical properties are similar to those of Al2O3 ceramics.Insulation performance, greater than 15 kV/cm;Thermal expansion coefficient matching silicon and silicon carbide。Non-toxic, good heat shock resistance, resistance to plasma erosion...Based on the above characteristics, aluminum nitride powder was once considered to be a national strategic key material。It can be said that from household appliances to automobiles and high-speed rail power components, aluminum nitride ceramics must be used。However, this technology has always been monopolized by Japan。

"If China can't even produce this, how can it be called an economic power??Somebody's got to step up and do it。As the first doctor in China to graduate from aluminum nitride as a research topic，Qin Mingli led the research team since 1992 has been committed to the research of aluminum nitride powder materials and ceramic products，Two technologies, high grade aluminum nitride powder preparation technology and complex shape parts forming technology, have been obtained，It is the result of the joint efforts of several generations。

"I went through a lot of heartache。Once discouraged, also disappointed, but every time in the purchase of Japanese aluminum nitride powder and deeply stimulated by the kind of high attitude, tangled, while being the relevant friends, peers and defense institutions and other people eagerly look forward to。So we gathered our courage and carried on。”

Success is always reserved for those who are prepared and diligent。After unremitting efforts, the product came out in anticipation。Today, the two technologies effectively solve the problem of difficult processing of complex shape products caused by high hardness and brittleness of aluminum nitride, and realize the precision manufacturing of miniature and complex shape high thermal conductivity aluminum nitride products, which are successfully applied to the preparation of key components of national defense weapons and equipment。

Breakthrough in the industrialization of aluminum nitride powder

"The last mile"

In the first time that Qin Mingli's academic research made a major breakthrough, Guan Junkai, who has many years of experience in semiconductor electrical appliances, keenly felt that the "spring" of aluminum nitride in China was coming。One day in 2012, the two brothers met in Beijing。Guan Junkai tentatively put forward the idea of making aluminum nitride materials。However, it got a vague reply that Qin Mingli's technology was "not too mature"。Nevertheless, Guan Junkai decided to find Shi Lei to discuss related matters。

Guan Junkai did not expect that aluminum nitride, which has high thermal conductivity, low dielectric constant, and good electrical insulation characteristics, is extremely suitable for being the basic raw material for the bearing substrate of high-brightness LED wafers and high-power electronic components, deeply touched Shi Lei, who has been engaged in the small home appliance industry for many years。After the two discussed the possibility of entrepreneurship with Qin Mingli many times, especially under the encouragement of the national policy to encourage university teachers to start businesses with results, Qin Mingli finally summoned the courage to start a partnership with technological achievements。

One day in 2016, Qin Mingli took the initiative to meet Guan Junkai and Shi Lei to discuss matters related to the industrialization of aluminum nitride。After discussion, the three agreed that this "people have no I have" technology, will have a bright market prospects。"Overall, the total demand for aluminum nitride in the domestic market is about 5,000 tons per year。The output value of aluminum nitride powder raw materials is close to 5 billion yuan, and aluminum nitride ceramic products are 30 billion yuan。My early career tells me that to be a business is either to be a brand or to be a basic raw material。Only in this way, the fate of the enterprise will not be subject to others。"Shi Lei said。Subsequently, the three decided that whether it was to break Japan's monopoly on China's aluminum nitride raw materials, or to achieve aluminum nitride industrialization, the project was worth the battle。

In December 2016, Guan Junkai and Shi Lei raised 5 million yuan in self-financing, Qin Ming donated technology, and the three people jointly established Xiamen Jujia Technology Co., LTD。Qin Mingli is the Technical director, Guan Junkai is the chairman of the company, and Shi Lei is the general manager of the company。Although the initial funds are not enough to support the entire production of aluminum nitride powder, Shi Lei, who has many years of senior management experience in the boiling pot and induction cooker division of Jiuyang Co., Ltd. firmly believes that what entrepreneurs lack is not money, but a sense of mission。

Responsibility lies in doing

Be a business with a sense of mission

After the establishment of Xiamen Juhua Technology Co., LTD., the "elders" of the three companies took the core team to the front line to personally grasp the production。One is to save costs;Second, I can directly grasp the process of the project。Because the mixing workshop is not ventilated and can not install air conditioning, it is often hot and sweaty。Even so, in order to get first-hand data and ensure that the product can have better quality, Shi Lei still insisted on working all night in the workshop, watching the sintering furnace, debugging equipment, and even going to the outdoor climbing to monitor the water tower。"Especially in winter, the huge temperature difference often makes people feel like fire and ice。Especially in the middle of the night, we can't see five fingers, we still have to insist on climbing outdoor to monitor the water tower, which is very dangerous。"Shi Lei said。

Seeing that the three more sleep and five more days have been improved, disagreements inevitably occur。"The biggest differences are in product line planning and sales planning，Qin Mingli's idea is to do it one by one，Strive to make the product perfect，It's not enough to match the quality of your competitors，It is better to surpass;And Guan Junkai and I thought the sooner the better，As long as it meets the quality of competitors, it will be listed，To seize the market，And it takes multiple products to work together。"Shi Lei recalled。Three partners, one from a university, rigorous academic attitude told him to do technology to be down-to-earth;The two are from the market, and more than a decade of market experience has taught them that the market is likely to be fleeting。Finally, after negotiation and analysis, the three people finally reached an agreement: as long as the product reaches the same quality as the competitor, it will be listed first, and then improved in the use process;Can not be on multiple series of products together, to a series of products listed to ensure the quality of the product。In the continuous run-in, Xiamen Jushi porcelain company has gradually grown up。At present, the company has signed two technology transfer (patent) contracts with the University of Science and Technology Beijing, the introduction of aluminum nitride powder and ceramic production technology patents, compared with Japan, the price, type, cost are an absolute advantage, there is no similar domestic competitors。

Today, in Xiamen Juporcelain Technology, the processing efficiency of aluminum nitride has increased from less than 10 pieces per day to more than 10,000 pieces per day by a single machine, achieving batch and stable production of aluminum nitride powder, with controllable particle size, high purity and low cost。The preparation of high purity nanometer aluminum nitride powder is realized, which provides the possibility for the preparation of high strength and high thermal conductivity aluminum nitride ceramics by low temperature sintering。"Zhihui Qiantang Win-win Future" Qiantang Star ·2017(second) Innovation and Entrepreneurship Competition preliminary competition, the project stood on the stage of innovation and entrepreneurship competition for the first time。It is also this time that Xiamen Science and Technology Fund has thrown out an "olive branch" and invested an additional 5 million yuan。Under the operation of the capital, at present, the company has built a production line equipment with an annual output of 30 tons of aluminum nitride powder, and it is expected that the production capacity of aluminum nitride powder can be expanded to 80-100 tons in 3 years, and the initial establishment of an annual output of 10 tons of high thermal conductivity complex shape aluminum nitride precision device production line equipment。

During the sixth China Innovation and Entrepreneurship Competition, many venture capital institutions took the initiative to discuss and expressed their willingness to invest large sums of money to help aluminum nitride projects do market industrialization。"This is really surprising to me, when the company was founded, we originally considered the use of their own capital, snowball development.。Unexpectedly, the China Innovation and Entrepreneurship Competition has "blown" so much social capital for us!For the various "unexpected" during the competition, Shi Lei was overjoyed。

"Next, we will also take the China Innovation and Entrepreneurship Competition and the love of all sectors of society, feedback to the society.。We believe that when the enterprise can truly create value for the society, the performance of the enterprise will be uninvited。"Shi Lei said。
