The 11th China Innovation and Entrepreneurship Competition (Guangdong-Guangzhou Division) and the 2022 Guangzhou Science and Technology Innovation and Entrepreneurship Competition are under the guidance of the Torch High-tech Industry Development Center of the Ministry of Science and Technology and the Guangdong Provincial Department of Science and Technology, and hosted by the Guangzhou Science and Technology Bureau. It is organized by the competent science and technology departments of various districts and the Greater Bay Area Science and Technology Innovation Service Center. The competition was successfully held from August 2 to 8.
1,500 companies from six industries of new generation information technology, biomedicine, high-end equipment manufacturing, energy conservation and environmental protection, new materials, new energy and new energy vehicles participated in the competition by uploading videos online to start a fierce "cloud" duel.
Congratulations to Guangzhou Putong for the first time participating in the competition, that is, for the project of "Bidirectional Film Biaxial Extensometer", which stood out in the competition and entered the semi-finals. I wish Guangzhou Putong will continue to work hard and achieve better results in the next competition!
Film biaxial tensile tester is a common equipment for testing the biaxial tensile properties of polymer sheet films. The film biaxial stretching instrument developed by Guangzhou Putong can make the thickness below 0.2-2mm, and the minimum 70×70mm can be used as a thick film sample of biaxially stretched film material. According to the required stretching ratio, it can be formed at a suitable temperature and time. The film tensile test is used for physical and chemical testing and analysis in the laboratory. According to the properties of the sample film, a wide variety of additives and formulas can be re-determined and applied to the production line, which can greatly reduce the trial production cost.
