Wang Liping: A material scientist who competes with "corrosion"

China is ushering in a new era of strong charting.
Marine materials with stable performance and long service life are inseparable for managing the ocean and developing the marine economy.
Someone has made statistics that the economic loss caused by seawater corrosion in our country exceeds two trillion yuan every year.
Wang Liping, director of the Key Laboratory of Marine New Materials and Applied Technology of the Chinese Academy of Sciences, is one who fights corrosion.
Over the years, Wang Liping has led the team to overcome difficulties in new fields such as marine anti-corrosion coatings, and has achieved fruitful research results, putting more and more high towers, ships, and bridges on the anti-corrosion "coat".
In April this year, Wang Liping was awarded the 23rd "Chinese Youth May 4th Medal", the only individual in our province to win the prize.
Research also bitter musicin August 2015, Wang Liping and his family's departure from Lanzhou, northwest China, came to the port city of Ningbo, Key Laboratory of Marine adding new materials and application technology of Chinese Academy of Sciences.
For more than 10 years, Wang Liping has been engaged in the research of space anti-wear and lubricating film materials and their aerospace applications, but then he has to shoulder the burden of new marine materials and application research.
The challenges are imaginable.
"As a scientific researcher, the happiest thing is to see my scientific research results take root, be applied and promoted.
As a port city, Ningbo not only has the most real experimental sites, but also the rapidly developing new material industry.
At that time, it was a rare opportunity for me.
" Wang Liping said.
Based on a large number of investigations and studies in the early stage, Wang Liping keenly realized that graphene modified anticorrosive coatings should not just stay in the laboratory and papers, but should be quickly transformed into new materials that have large-scale applications and can be industrialized.
He quickly organized a team to conduct technical research and environmental tests.
In just two years, a series of graphene modified long-term heavy-duty anti-corrosion coatings and functional coatings with high technical indicators came out one after another.
The key technical indicator-salt spray resistance life exceeded 6000 hours.
.
Scientific research is very hard, but also very happy.
Interview, Wang Liping repeatedly said that scientific research is a job he likes, "the era of development, social progress, national care and support for scientists unprecedented, this is the best era of scientific research.
" WentThe road to scientific research in the South China Sea will not be smooth sailing.
A key technical problem facing Wang Liping's team is the large-scale dispersion of graphene during the mass production of coatings.
"After repeated demonstrations, we found that the process requirements of the laboratory did not meet the actual production requirements, which forced us to carry out process innovation.
" Wang Liping decisively gave up the original ideas and led the team to continuously optimize graphite with the help of trial and error and feedback from the company.
The olefin modification technology finally ushered in a breakthrough five months later-the new modification method is not only simple in process, but also greatly reduces the cost while meeting the requirements of dispersion and coating performance.
  Process improvement directly promoted the rapid setting of graphene modified heavy-duty anti-corrosion coatings.
Three months later, the first industrialized product of graphene-modified heavy-duty anti-corrosion coating was demonstrated and applied in the protection project of the transmission tower of Ningbo Power Grid.
 The initial success in the development and engineering application of new anti-corrosion coatings did not make the team leader Wang Liping feel at ease.
"The laboratory data of materials is only an accelerated test in a single environment.
A new type of coating must undergo long-term performance evaluation in a natural environment to ensure its reliability.
"   Wang Liping thought of Hainan Wenchang.
The tropical marine environment with high temperature, high humidity and high ultraviolet radiation is the best test for anti-corrosion coatings.
The summer is very hot.
In order to speed up the progress of the experiment, Wang Liping led the team members and set off from the laboratory at 3 in the morning.
"The sun and the wind blow, and staying on the beach is a whole day.
"   Wang Liping still remembers that on the small island of Xisha surrounded by the sea, their research equipment has been baptized by numerous storms; at noon in July, the equipment steel The surface temperature of the structure is as high as 80 degrees Celsius.
.
.
The team members are installing and maintaining various test equipment and equipment under such rainstorms or scorching sun.
Over the years, Wang Liping became darker and thinner, but his eyes still gleamed when he talked about that experience.
Team combat strength is sufficient   "This honor is not mine alone, it is the result of teamwork.
" After winning the "Chinese Youth May 4th Medal", Wang Liping often emphasized the strength of the team.
  For the management team, Wang Liping has his own wisdom.
Some people are nervous as soon as they come on stage and can’t say a word, but they can calm down to do experiments and write reports; some people don’t like to write articles, and they don’t want to stay in the laboratory, but they can go to the scene to solve practical problems.
.
Wang Liping has created conditions for them to give full play to their strengths.
  "Everyone has their own strengths, and every young person wants to excel.
A good team is to be good at making good use of talents with different characteristics.
" Wang Liping said.
  "To do scientific research, we must be down-to-earth.
" This is the working principle set by Wang Liping for the team.
Dr.
Liu still remembers one time when Wang Liping talked to him and told him that he must go to the company for on-site inspections to understand the actual production process of the product.
"Only such R&D can truly meet the needs of society, and the results can really be used by enterprises.
"   "Compared with young people who have just entered the laboratory, we have a broader vision and more resources, so we should fight for more for everyone.
For projects, build more platforms.
" Wang Liping said.
Under the leadership of Wang Liping, the team members seem to have a "willing to be a ladder" idea.
Members doing basic research generously share their data, members doing applied research continue to put forward their own new ideas, old employees take the initiative to help new members.
.
.
the whole team is like a family, living in harmony.
  The hearts of the people are united, and the mountains move.
The Ningbo Institute of Materials, Chinese Academy of Sciences has an innovative "iron army" of new marine materials.
In recent years, Wang Liping’s team has independently developed 8 series of anti-corrosion and wear-resistant coatings such as graphene-modified marine heavy-duty coatings, which have been widely used in the national grid transmission towers, multi-functional marine platforms, and large-scale petrochemical equipment.
The team’s achievements have also been successfully applied to key components such as aerospace turbopump power system, aerospace solenoid valve, and high-temperature gas-cooled reactor drive system for the first time, solving the technical problems of strengthening and protection integration of some core components in major national breakthrough projects.
  Innovation is endless.
"Advancing into the deep sea is a trend.
There are not many people doing deep sea equipment in terms of corrosion resistance and reliability.
Many things are groping, and the material system is still unclear.
We need to deploy in this field in advance and increase research and development.
We will work hard to produce more results with practical application value as soon as possible.
" Wang Liping said.
