The "Tu" of the School of Materials of Huazhong University of Science and Technology becomes the "gold" practice team — a good idea of using professional knowledge

What kind of spark will you combine the professional technology you learned with social practice? The practice team of the School of Materials of Huazhong University of Science and Technology came to Lincang, Yunnan. In three years, it wrote a paper for rural rejuvenation.

Primitive production, well -developed development

In the summer vacation of 2020, for the first time, the practice team set foot on Lincang's land, which was attracted by a material called "Kaolin". Through practical visits, they found that the local kaolin reserves huge reserves and excellent quality. Kaolin is widely used, suitable for various fields such as ceramics, papermaking, and fire prevention materials. It is especially suitable for ceramic manufacturing with its high -quality mineral ingredients.

However, through further research and development, the local mineral processing process can only be simply removed of high -mortar and washing of kaolin, and cannot be made into more fine kaolin powder. At the same time, although Lincang has a historical accumulation of soil pottery production for nearly a thousand years, it lacks modern, mechanized, and automated production equipment. It still produces earth pottery products in the form of small workshops. Long kiln, which has a history of nearly a century, has low finished products and uneven quality. Whether it is sold to the outside world after rough processing, or the original soil production, this extensive resource development is a low value -added kaolin resources waste.

"Why don't we try to use kaolin to do something?" Huo Yufan, the captain of the practice team, thought of 3D printing in the classroom, made kaolin into a ceramic 3D printing raw material, and created a crafts with a sense of technology. As soon as the team members were shot, they immediately conducted experiments for feasibility studies.

Scientific and technological innovation, ordering soil into gold

In 2021, when he returned to school, the team members conducted a professional physical and chemical performance representation of Lincang Gaolin in the laboratory. They found that the kaolin particles with a ball -grinding particle size were uniform, good liquidity, and high profile. It was suitable for ceramic 3D printing Raw material powder.

After more than a year of concentration of scientific research, the practice team has developed four core technologies specifically targeted at Lincang Gaolin, based on the research direction of Kaolin ceramics 3D printing, and based on a full set of 3D printing equipment and practical team 3D printing technology accumulation. Get 3D printing parameters suitable for Lincang Kaolin. These technologies cover the entire process of kaolin materials from the pre -processing, 3D printing process, post -processing of the body, and finished sintering.

When it comes to the biggest problem encountered in the research and development process, Zhang Yijia, a member of the practice team, said: "Our kaolin powder and pulp that meets the 3D printing requirements is not a simple raw material. It is necessary The mixing agent and other additives can meet the material performance requirements of 3D printing. "

Compared with the local traditional Tao pottery preparation process, this technology can not only help complex shape ceramics that can not be processed efficiently, but also have extremely high R & D efficiency when developing new products, and use clean energy to achieve energy conservation and emission reduction. Low -carbon environmental protection.

Science and technology empowerment, cultural innovation

The production of 3D printing ceramics is not the end point, but the starting point of cultural innovation. In order to make 3D printing ceramics appreciation, the practice team decided to look for design inspiration based on the unique national culture of Lincang. In the summer of 2022, the practice team came to the gathering place of the minorities of Lincang again.

In the Laupu Township of the South American South American, the practice team inspected the history and origin of the Laupu nationality, and learned about the folk customs of Lusheng, wearing bamboo baskets, and "bridge festivals". The characteristic building "Wooden Palm Tower", what impressed the team member Ma Xiaoqian was the local national totem -left mouse, right rice bird, middle golden gourd, and every family's eaves and beams were everywhere. The practice team uses this as a source of creativity, combined with the technical advantages of 3D printing, and produces a three -dimensional ceramic gourd and gourd pendant on the Kaolin 3D printing production line of Kaolin Company, Lincang, to create a complex structure ceramic that cannot be achieved by traditional craftsmanship. product.

3D Printing Kaolin Ceramics Crafts Ao Linyu Photo

At the Zhongshan Bamboo Art Museum, the team members Junbin found that the bamboo silk buckle ceramic tea set products have high process value. The craftsman is woven into a tea bowl, a tea cup and other appearance shapes, and then combined with the bonding method of bonding and ceramic. Essence

As a result, the practice team thinks that the ceramic gourd is the carrier, and uses 3D printing to achieve the scene of the "bridge festival" of the Laupu tribe on the surface; use 3D printing technology to restore the three -dimensional "wooden palm building" in the form of kaolin ceramic sculpture; Using 3D printing kaolin ceramics to combine bamboo weaving to make bamboo silk buckle ceramic products, which can not only solve the problem of accuracy and improve production efficiency, but even make more complex shapes and structures to achieve the empty artistic creation ...

Taking local kaolin resources as the raw material, advanced 3D printing technology as the manufacturing process, unique civil customs as product connotations, and developing high -value -added ceramic cultural products are demonstrations to promote the combination of production, university and research, realize the sharing of school resources, and promote industrial upgrading New ideas.

Green mountains and green water, light up reality

When it comes to the "Diantu Gold" practice team and the project, Professor Wu Jiamin of the Practice Teacher's School of Materials Materials said: "In the past three years, they have used the professional technology they have learned in the classroom to promote the development of regional characteristic industries with scientific research results.Extension and sublimation. "The person in charge of the Lincang Jade Ceramics Cultural Manor said:" The introduction of the Kaolin Ceramics 3D printing production line has promoted the development of the Ka Lingto ceramics industry in Lincang District, which is a disruptive innovation.The application industrial chain of Cangena Mountain Minerals has strengthened the Lincang ceramic production industry chain and filled the Lincang high -end manufacturing industry chain. "

The pen of social practice and scientific research innovation, write the rural rejuvenation papers on Lincang land, guard the green mountains and green mountains with high -tech, create Jinshan Yinshan with high -end manufacturing, and improve people's happiness with emerging industries.Then there is dreams, but the pace and strength of the students.(Author: Liu Ziling, Huo Yufan Zhang Yijia Meng Di)
