Liu Zeshun: Tackling Key Experts And Developing New Materials Tens Of Millions Of Years

In major shopping malls in Qingdao

Counters often see such a person: whether it is

,

Or children's shoes, he must take it up and study it carefully until he understands the structure of shoes. He is Liu Zeshun, chief technology officer of Qingdao Hengda Limited by Share Ltd.

Since entering Hengda in 1991, Liu Zeshun has been dealing with shoes for more than 25 years.

As a famous "shoe idiot" in the company, he led the team to overcome difficulties one after another, and launched many products recognized by the market.

Liu Zeshun, 46, chief technology officer of Qingdao Hengda Limited by Share Ltd, was named "Shandong provincial chief technician", "provincial outstanding contribution to young and middle-aged experts", "Qingdao chief technician" and so on.

Key research and development of new materials tens of millions of years

In 1991, Liu Zeshun, who graduated from high school, entered Huda as a worker in the shoemaking workshop. Because of his outstanding work achievements, he was sent to Shanghai textile school by the company, and embarked on the road of leather shoes research and development since then.

In 2007, Hengda is going to launch a waterproof and breathable functional leather shoes, but it needs a kind of space waterproof and breathable technology. This technology has been used in the production of space suits, but for a long time, the core of technology has not been grasped by Chinese shoe companies.

The task of tackling technical difficulties lies on Liu Zeshun. The difficulty of the technology is that both waterproof and breathable conditions need to be met at the same time. Waterproofing requires that the shoes have strong tightness, and that they require enough "openings" for shoes, which are difficult to balance.

Liu Zeshun and his colleagues worked hard day and night to tackle technical problems. Many times they only had one meal a day.

After years of trial and error, he and his team developed a kind of thermal plastic material, which has both airtight and breathable properties, and 900 million holes in 9 square centimeters can block the invasion of water molecules and allow water vapor to pass through.

This technology later won the national new patent, and the leather shoes made of this space waterproof and breathable technology were also recognized by the market.

In the highly competitive leather shoes manufacturing industry, who has independent R & D technology, who can have the initiative in the market.

In 2002, Hengda began working with world famous brands such as Monte Carlo and introduced international advanced shoemaking technology. One of the highlights of the study was leather seamless bonding technology research and experiment, which fell on Liu Zeshun's shoulders.

Through the high frequency seamless bonding technology, the broken leather is fused to improve the utilization ratio of leather to 7-8%.

Liu Zeshun's colleagues counted out the reporters. According to the calculation of 25 yuan for each piece of leather, an average of 2 feet of leather was required for each pair of shoes.

After leather seamless bonding technology, each pair of shoes can save 4 yuan. According to the annual production of 10 million pairs of shoes, this technology can save tens of millions of dollars per year for the company.

The six hundred test of technology, the introduction of filial shoes

Once again, led the team to overcome technical difficulties, Liu Zeshun gradually became the company's technology major.

In 2010, Hengda wishes to introduce a special shoes for middle-aged and old people with "filial piety" as the theme, which is comfortable, light and skid resistant.

This kind of functional shoe has very high requirements for soles, and the highest requirement is the skid resistance function.

After comparing the materials, Liu Zeshun finally selected the higher cost natural rubber as sole material, but this did not completely solve the problem of skid resistance.

At this time, he thought of the tire with the most similar material to the sole.

According to the principle of tire, he has set up many micro channels on the soles of filial shoes. After many tests on water and oil surfaces, it is found that these shoes with micro channels will not slide on the ground with oil and water mixture.

Liu Zeshun said, at present, there are many antiskid series soles on the market, but it is very difficult to achieve the function of anti-skid ultra light.

He led the team day and night trial production, ranging from dimensional inspection, data analysis and calculation, material process optimization, performance test analysis, thickness adjustment and so on, and did not let go of any details. Finally, the design of 8 story bottom materials was adopted. After a year and about 600 tests, the production technology of filial shoes with the proprietary property of Hengda was successfully developed, and technological innovation and optimization were perfected, which greatly improved the production efficiency.

Industry leaders participate in the formulation of national standards.

In the eyes of family and colleagues, Liu Zeshun is a real "shoe idiot" who devoted most of his work to shoes.

Liu Zeshun jokes that he sees people at the first sight by looking at the shoes they wear and studying the structure and shape of the shoes.

Once, on the way, he saw someone wearing a pair of shoes with a structure and style that he had never seen before. He asked the other person to take off his shoes and show them himself.

In his spare time, he often goes to shoe town to see the fashionable styles in the market.

It is because almost all the time is placed on shoes that Liu Zeshun constantly creates new shoe making techniques.

Since 2003, he has hosted 5 patents, including "one kind of leather products seamless bonding method", "last technology and shoe last", and so on. He has won the national invention patents, and 46 new utility models, such as waterproof and breathable shoes and magnetic health insoles, have won the national utility model patents. In the new products, new technologies and scientific and technological achievements, the 27 new products and technologies that he participated in the research and development of "new type thermoplastic elastomer (TR) materials, such as massage and shock absorbing shoes" and "filial shoes making technology" and so on, have reached the international leading level and advanced international level through the appraisal of Qingdao economic and Information Committee.

Liu Zeshun has also been involved in the formulation of national standards for many times due to his outstanding business.

He took part in the five industry standards such as leather sandals, and the footwear strength test method has been implemented since March 1, 2008.
