Leather High And New Technology How To "Pform The Traditional Industry"?

In the world of leather, researchers enjoy it.

Fan Haojun believes that promoting industrial innovation is a very real thing. It needs a group of people who are far away from the noisy and willing to sit on the bench. And only by holding such a spirit can we really succeed.

What is the effect of adding raw materials such as graphene and other raw materials into leather?

In a few days, Fan Haojun, deputy director of the National Engineering Laboratory of leather cleaning technology, Sichuan University, is going to Jiangsu.

It sounds that the destination, a company engaged in graphene research and development, has nothing to do with its national engineering laboratory. Graphene is commonly used as a new energy battery.

"It is very important to add graphene to leather, which can improve fire resistance, wear resistance, scratch resistance, antistatic and leather properties."

Fan Haojun said that high and new technology will make the traditional industries "reappear" and take off again.

The National Engineering Laboratory of tannery cleaning technology is the only national engineering laboratory in the field of Leather Chemistry and Engineering in China. It has also become the "source" of the leather industry pformation and upgrading. The task of fan Hao Jun and his colleagues is to make this normally backward industry different.

"What do you think the instrument can do?" asked Fan Haojun in a lab, pointing to a device like a photocopier. The puzzle was still solved by him: "it's an atomic force microscope, which can measure the nanometer structure of materials, much more powerful than the ordinary microscope."

From the 1 floor to the 4 floor, it is the "site" of the laboratory.

Chroma chromatic aberration analyzer, thermogravimetric analyzer, plasma emission spectrometer...

All kinds of high-end equipment are dazzling.

The value of these devices exceeds 100 million yuan.

The reporter saw that every small lab had one or two teachers or students busy inside, and they could get in and out 24 hours a day.

The laboratory's "national weighing apparatus" is free for students to use. The annual cost of materials and maintenance is more than 600 thousand yuan.

"A probe for observing the structure of a fiber will cost four hundred or five hundred yuan a year for 150 yuan."

In the pition from simple to high-end, these devices have come out of a number of cutting-edge talents in China's leather industry.

Shi Bi, a member of the Chinese Academy of engineering, is one of the top honors of the international leather technology industry.

What kinds of problems do enterprises encounter? Do they not cooperate with laboratories? "There are two main categories: one is to improve leather physical properties, such as smooth, antibacterial,

The other is environmental protection, such as cadmium removal from wastewater.

China has become a world recognized leather producer, but

But it gives people the impression of being backward, not only the quality of leather is not high enough, but also the "three wastes" emission of production enterprises.

The lab will take a whole layer as an engineering laboratory.

"Concentrate" in order to simulate, analyze and solve the specific problems existing in enterprises.

Beside a machine lay raw materials of wool just arrived.

Fan Haojun said that the traditional way to make leather from leather is to dissolve it with chemical raw materials, but this increases the pollutants in the waste water.

"Now enzyme technology is used to protect wool from hairs, which not only increases the value of leather, but also reduces pollution."

The reporter pinched the black pigskin half finished on the dyeing machine. Fan Hao Jun added that the dyeing process has made a major breakthrough now, and the dyeing wastewater can be avoided by supercritical carbon dioxide supercritical water free printing and dyeing technology.

In the other cutting corner of the engineering laboratory, there are piles of some leftover bits and pieces.

"This is a treasure."

Fan Haojun said with a smile that these former "waste residue" can be made into collagen fibers. After a "modification", they can be used to adsorb cadmium in wastewater and become an environmental protection tool.

Many advanced scientific and technological achievements in leather laboratory have been applied in some enterprises in a small range.

"Now the application cost is relatively high, for enterprises, these technologies are more like lighthouses, so that they can see the future direction."

There are more than 40 research teams in tannery laboratories, mainly young people aged 30-40, 80% are doctors, and more than 40% have overseas experience.

What makes them proud is that the annual SCI paper is published more than the other famous research institute, India central Leather Research Institute, which has more than 100 researchers.

As a senior member of the team, fan Hao Jun often communicates with young people the direction of innovation.

"We are applied disciplines. We should not be too narrow minded. We should not think that innovation is the only thing that others have not done."

"The amount of 20 other processes completed by 15 processes is innovation, and the utilization rate of others is 70%. I get 90%, and it is also innovation."

Paying close attention to the frontiers of various disciplines and even "stealing teachers" is another "special skill" of this team.

Fan Haojun jokes that the inspiration to add graphene to leather is to listen to a product that is independent of discipline.

Researchers in tannery laboratories often rub up research conferences that seem to have no cross sense.

Sometimes, they also delight in the "selling point" of the results promotion.

"Do not need to go to the big forest, leather products can also distribute negative oxygen ions, is it cool enough?"
