A major problem in prefabricated steel structure painting has been jointly overcome!

On September 17, 2021, a scientific research project jointly carried out by Shenzhen General Institute of Architectural Design and Research Co.

The scientific and technological achievement appraisal meeting was presided over by Liu Fuyi, secretary general of Shenzhen Society of Civil Engineering and Architecture, and by Lou Yu, chairman and chief engineer of China Electronic Engineering Design Institute, national engineering survey and design master, Professor Zhang Ailin, president of Beijing Construction University, and chief engineer of East China Institute of Architectural Design and Research , Zhou Jianlong, National Engineering Survey and Design Master, Ge Jiaqi, Chief Expert, Chief Engineer, and National Engineering Survey and Design Master of China Aviation Planning, Design and Research Institute, Professor Chen Zhonghua from South China University of Technology, Chief Engineer and Professor-level of China Academy of Building Research Co.

Liu Qiongxiang, chief engineer of Shenzhen General Institute of Architectural Design and Research Co.

It can meet the requirement of no major repairs for prefabricated steel structures for 30 years

The subject of "Key Technology Research and Application of Waterborne Anticorrosive Coatings for Prefabricated Steel Structures" started in 2018.

The results appraisal meeting began.

After review and appraisal by the expert committee, it was unanimously agreed that "the developed water-based heavy-duty anti-corrosion coating structure has good stability, strong sealing, salt spray resistance up to 3,300 hours, and aging resistance up to 3,500 hours, effectively improving the structure of the water-based heavy-duty anti-corrosion coating.

 From discussion to practice

The high degree of industrialization of prefabricated steel structures, fast construction speed, short construction period, and fastest projects are one of the development trends of China's construction industry, and it is of great significance to promote China's construction industrialization

Although traditional solvent-based coatings can meet the anti-corrosion requirements of steel structures, they contain a large amount of volatile organic compounds, which will cause harm to the surrounding environment and construction personnel during use, and do not meet the requirements of national environmental protection policies, and the material components are flammable Explosive, neither environmentally friendly nor safe

On August 18, 2018, the National Steel Structure Conference was held in Shenzhen.

On November 5, 2018, a joint research team composed of Shenzhen General Institute of Architectural Design and Research Co.

 Practice is the only criterion for testing truth

"Research and Application of Key Technologies of Waterborne Anticorrosive Coatings for Fabricated Steel Structures" is the subject of research and development of water-based anticorrosive coating products, supporting coating systems and coating processes that can achieve 30 years of anticorrosion and minor repairs for fabricated steel structures

At the beginning of the subject research, under the initiative and coordination of Liu Qiongxiang, chief engineer of the Shenzhen General Institute and the first engineering survey and design master of Guangdong Province, the three units selected outstanding soldiers to form a joint technology research and development team

In the subject research, the project members of Jitai Co.

As early as 2009, Jitai Co.
, Ltd.
reached an agreement with Maoming Petrochemical and South China University of Technology.
The waterborne epoxy electrostatic conductive anticorrosive paint in tank jointly developed by Sinopec passed the scientific and technological achievements appraisal of Sinopec.
It is at the leading level in the world” and it is recommended to promote its use
.
From 2009 to 2019, the product has been tested, applied and improved for nearly 10 years in Maoming Petrochemical.
On this basis, a full range of water-based anti-corrosion products inside and outside storage tanks, devices, and pipelines have been developed to meet the needs of petrochemical anti-corrosion products.
The need for safety and environmental protection has been highly recognized and universally welcomed by equipment workshops and construction personnel
.

In 2011, Jitai Co.
, Ltd.
, CIMC and South China University of Technology joined forces to develop the "Waterborne Metal Anti-corrosion Coating for Containers" through the Guangdong Provincial Department of Science and Technology
.

In 2012, Jitai Co.
, Ltd.
cooperated with South China University of Technology, and through the Guangdong Provincial Department of Science and Technology approved the research and development of "waterborne polyurethane anticorrosive coatings", and entered the high-end anticorrosion field
.

In 2019, Jitai was invited to participate in Sinopec’s "Ten Dragons" scientific and technological research project hosted by Sinopec Pipeline Storage and Transportation Co.
, Ltd.
-"Large Crude Oil Tank Farm Safety and VOC Emission Reduction Technology Development and Application" sub-project storage tank water Study on the applicability of coatings
.
Overcoming difficulties, Jitai water-based paint was successfully applied in Huangdao Oil Depot and passed the acceptance inspection, and the project team successfully completed the task in collaboration with the project team
.

Jitai Co.
, Ltd.
always actively promotes the development of the industry, spares no effort in the important and difficult issues of the industry, and actively participates in it! Over the years, we have accumulated a wealth of practical experience, with a complete R&D team and mature advanced technology
.
Has provided more than 3 million square meters of petrochemical storage tanks, pipelines and equipment, as well as more than 200 steel structure customers and projects with "safe, healthy and environmentally friendly" products.
Classic projects include Guangzhou*** International Airport Phase II, Beijing Daxing Airport, the Three Gorges dam power plant, carbon Kunming Expo Center, Qufu Olympic Sports Center, Nanning and peaceful Spring City and so on
