On the evening of January 5, Zhongtian Technology issued an announcement that the metal (aluminum)-based graphene composite material (hereinafter referred to as composite material) jointly developed by the company and the Institute of Process Engineering of the Chinese Academy of Sciences has recently made breakthroughs
.
Under the premise of ensuring the realization of laboratory performance data, the composite material has been successfully trial-produced on the industrial continuous casting and rolling production line, which is a key step
in the development of graphene in the field of metals.
Graphene and its related application technology is currently a hot spot in the world, which has unique two-dimensional structure, high strength, high electrical conductivity and high thermal conductivity and other super mechanical and functional properties, which is considered to be the most ideal composite reinforcement phase, and the research of related topics has also become a hot spot
in the field of composite materials 。 The metal-based graphene composite material project jointly carried out by Zhongtian Technology and the Chinese Academy of Sciences Process aims at the key bottleneck in the field of aluminum and aluminum alloy overhead wires, that is, the contradiction between tensile strength and conductivity of Zhongtian's existing main industry----, that is, the contradiction between tensile strength and conductivity, and aims to greatly improve the tensile strength
of materials under the premise that the conductivity of traditional materials does not decrease or decreases slightly.
The results of this project will provide a new and revolutionary wire product option for China's power system construction, and the new wire varieties derived will make breakthroughs
in many fields such as energy saving and consumption reduction, heavy ice resistance, and large leapfrogging.
The project successfully prepared aluminum-based graphene composite rods in batches using the industrial continuous casting and rolling method for the first time in the world, which will have higher production capacity and lower cost than the previous batch production, which is of great significance
to the future industrialization of the composite material.
During the implementation of the project, the tensile strength of the composite material developed by the targeted process is increased by 25%~50%, which is basically consistent with the data obtained in the laboratory research stage and the batch pilot stage, reaching the advanced level
of similar research results at home and abroad.
According to reports, the unique graphene addition process developed by the project not only effectively solves the problem of difficult wetting between graphene and aluminum, but also realizes the online addition
of graphene in the continuous casting and rolling process.
The mastery of this technology will not only provide support for the application of graphene in the field of aluminum for overhead conductors, but also can be applied in most aluminum and aluminum alloy materials, combined with other process allocation, so that the new composite materials can obtain more targeted performance
.
For example, in the process of lightweight development of transportation vehicles, "aluminum instead of steel" has become the main trend, with the help of graphene, the amount of aluminum can be further reduced, to achieve a greater degree of lightweight, its economic and social benefits are very significant
.
At present, Zhongtian Technology has carried out industrial layout for the technical achievements of the project, relying on its subsidiary ---- Shanghai Zhongtian Aluminum Wire Co.
, Ltd.
, a subsidiary of its main overhead conductors, with a total investment of 300 million yuan
.
At that time, the advanced technology will be first applied to aluminum and aluminum alloy overhead wire products, and then expand to a variety of metal products, which can form a new industrial growth point for enterprises, lead the development of China's high-end graphene composite technology, and bring good economic and social benefits
