Water-soluble green plastic bags, flame-retardant plastic boxes, liquid metal, graphene... In recent years, Dongguan has emerged a number of new materials and other industry leading enterprises, bringing together traditional and high-tech enterprises Qifei Yangcheng school reporter Tang Bo
Liquid metal, graphene, ENC nano... These new materials on the tall may seem far away from us. But plastic bags, bottles, clothes, etc., are an integral part of our lives.
During the just-concluded Tenth China Processing Trade Fair (hereinafter referred to as the “Gall Expo”), non-toxic and non-hazardous water-soluble plastic bags, tear-off clothes and other products once again opened the door to the public. : Traditional products can also be so unusual. The mystery of all this is due to the material.
Industrial manufacturing, materials first. In recent years, Dongguan has been promoting the development of new materials industry, emerged in the industry leading enterprises such as Yi'an Technology, Jubilee Technology, Hongna (Dongguan) new materials, and promote the traditional and high-tech enterprises to fly together, new materials The 'Dongguan Legion' in the field is accelerating.
Traditional industries emerge 'new things'
At this year's Gabo Fair, in front of the booth of the Guangdong Allied Group, the reporter saw an eco-friendly plastic bag called “polyvinyl alcohol”. There was no difference in appearance from ordinary plastic bags, but the staff put it in In the glass, after pouring into the water, a miracle happened: The plastic bag was actually dissolved in the water and turned into a milky white liquid.
'This liquid is completely non-toxic and harmless. It can also be used to irrigate plant compost. According to Peng Xianyu, a senior engineer at the Allied Group, PVA is an organic compound with properties between plastic and rubber. At the expo, they brought together universal water-soluble film, marine environment-friendly plastics, and plant-protected plastics. These new products can be used in different environments and fields, and eliminate white pollution.
'These three types of products have now been industrialized, and are undergoing long-term environmental testing and evaluation.' Li Shi, head of the NTU, revealed that after product development, it has been approved by the relevant national authorities and will be used for mandatory promotion in the logistics industry. The cost is only 20% less than the current ordinary plastic.
It is not only plastic bags. The plastic box on the booth of Dongguan Kisho Industrial Co., Ltd. is also very powerful. 'This is a new material modified by plastics. It belongs to the highest level in flame-retardant materials.' The reporter explained that while pulling out the lighter and opening the valve to the maximum, and directly firing the flame to burn the battery case with the outer flame, generally speaking, the plastic product ignites in a fire and releases toxic gas, but until about 15 seconds, Wang Yong The battery box on the hand is still intact.
Because of this, the plastic box made of 'Jishi Shuo' material was used on the lithium battery of the high-speed rail, and won the international authority certification to fill the domestic gap. Because of the special flame-retardant effect, the material is also widely used in aerospace, Fire safety, military equipment and other fields.
Segmentation ranks among the frontiers of the world
Referring to new materials, people naturally think of graphene as the "king of new materials." As early as February 2014, the world's first 1,000-ton graphene production line was put into operation in Dalang Town, Dongguan. The production line is Nano (Dongguan) New Material Technology Co., Ltd. has researched and developed. Two graphene slurry production lines can produce nearly 3,000 tons of graphene powder per year. Currently, Hongna Technology has obtained the certification of domestic major manufacturers of lithium battery batteries for electric vehicles. Has been large-scale supply.
After entering the Taili Technology Co., Ltd. in Hengli Town, the thin metal sheet and the metal frame of the mobile phone in the showcase could be changed in shape like a plasticine. The liquid metal in the Terminator was in Tai Yi Ying Tuo. Become reality.
Li Tianhua, the relevant person in charge of the company, told the reporters from Yangcheng that this new material was mainly imported from the United States and was developed by a team of South Korean experts. It has now successfully achieved small-scale mass production. Compared with traditional materials, liquid metal has strong toughness, good elasticity, and fast magnetization. Such advantages, can be used for mobile phone shells and accessories, medical equipment, precision manufacturing and aerospace and other aspects.
Compared with new materials such as graphene and liquid metal, the ENC nano waterproof technology developed by Easy Nano Technology Co., Ltd. is even more cool. In the face of media reporters, Xiao Chunquan, Chairman of Yi Neng Nano, has opened a cover. The mobile phone was thrown into the fish tank and was removed after an hour. After closing the back cover, it was still possible to call and go online.
It turns out that the key to ENC Nano Waterproof Technology is to form a nano-scale covering on any object surface to prevent it from being corroded by moist air, sweat and moisture, and not only limited to the outer shell of the object, but to cover the material to every zero. Among the components.
Industrial platform is gradually improving
In Dongguan, a number of innovative companies with large market scale and strong technical capabilities, such as Tai Yi Ying Tuo, Yi An Technology, Yin Yin Technology, Zhao Sheng Technology, Shang Xin New Materials, etc., are rapidly emerging and are deeply involved in the application of new materials. The new materials industry has formed an effective linkage. According to the online statistics of new materials, the output value scale of the electronic information industry in Dongguan ranks among the top cities in China. In the past two years, the total output value of the new materials industry has exceeded 50 billion yuan, and the new materials industry has exceeded 300 companies. .
Not only that, a large number of industrial platforms have also been established: On the 25th of last month, the Songshan Lake Materials Laboratory and the Institute of Physics of the Chinese Academy of Sciences in the Pearl River Delta Division unveiled the ceremony in Songshan Lake, aiming to lead the development of materials science world-renowned materials science research. The center and one of the world's new material sources for the production of new materials. Two years ago, the first professional research institute with the functions of graphene preparation, application, performance testing and other functions in Dongguan was also established in Dao Town, Dongguan. .
In May 2017, Dongguan issued the “Thirteenth Five-Year Plan” for the development of strategic emerging industries in Dongguan. It is proposed that by 2020, the scale of strategic emerging industries in Dongguan will exceed 500 billion yuan, and new materials will be listed as the seven key development directions. One of the academicians of the Chinese Academy of Sciences, Wang Enge, stated that the new materials industry is undoubtedly a big plus or even a major booster for a manufacturing-developed city like Dongguan.
