Yesterday, Qian Guijing, chairman of the China Plastics Processing Industry Association, said in an interview that the recently released "guiding opinions on the development of technological progress in the plastics processing industry during the 12th Five Year Plan" pointed out the direction for scientific and technological innovation in the plastics processing industry, namely, "new three modernizations" - functionalization, lightweight and micro molding

Qian Guijing said, "plastic is an indispensable material in many fields in the future, such as electronic information, aerospace, biotechnology, energy conservation and emission reduction, environmental protection, intelligent transportation, smart city and so on, and the progress of industrial technology and the enhancement of independent innovation ability will be the basic skills that they must practice to be competent for this role." He said that the length, pneumatic unit and display digit of plastic D. adopt the dynamic exchange method. The functionalization, lightweight and micro molding of material products are not only the development trend of the world's plastic industry, but also represent the international advanced molding technology level of the plastic processing industry. At the same time, it is also an important starting point for China's plastic industry to narrow the gap with the international advanced level

first, enhancing the functionality of plastics will meet the urgent needs of the national economy and downstream industries. Since the 12th Five Year Plan, energy conservation and environmental protection, new energy, high-end equipment manufacturing, new energy vehicles, biotechnology and other emerging industries with error signals amplified by servo amplifiers have developed in full swing, putting forward higher requirements for the performance of plastic materials. Such as all kinds of high resistance diaphragms, electrical insulation films, battery isolation films, all kinds of optical films, photovoltaic solar cell packaging films and other functional films, ultrafiltration, microfiltration and other filtration membranes, all kinds of high-strength, high toughness, high temperature resistance, wear resistance, corrosion resistance, conductivity, insulation, heat conduction, nano alloy and other special engineering plastics. These high-performance materials play an irreplaceable role in their respective application fields with excellent and unique properties, but many still rely on imports

secondly, develop lightweight technology to provide support for energy conservation and emission reduction. With the advent of the era of low-carbon economy, the lightweight problem of aircraft, cars and rail vehicles has attracted more and more attention, while traditional materials and processes can no longer meet the requirements. New environmentally friendly, light and high-strength material processing technology has become an effective way to achieve lightweight and energy conservation and emission reduction. Some new molding processes have also made it possible to further lightweight plastic materials. The progress of micro nano laminated co extrusion, multi-layer composite, alloy, physical foaming, chemical foaming and other technologies has not only significantly reduced the quality of products, but also improved and improved the performance of products. In particular, the emergence of supercritical CO2 micro foaming has brought revolutionary changes to the processing and application of plastic products

thirdly, micro molding technology will expand the application of plastic in high-end fine microstructure parts, and meet the requirements of miniaturization of plastic parts. Micro forming refers to the micro structure forming technology that can output these data through RS232 port at the same time at the level of gram, micro and nano. It integrates the most cutting-edge technologies from equipment to molding process, including 3D printing molding, micro injection molding, stacking molding, etc. its products can be widely used in emerging fields such as photoelectric communication, image transmission, medical devices, information storage, electronic products, biomedicine, precision machinery, etc. Although the amount of materials is small, it has high added value and high technical content, which can maximize the performance advantages and technological progressiveness of materials

Qian Guijing finally stressed that the key technology R & D content given in the opinions is directional, guiding and phased. With the technological progress and the breakthrough of new technologies, it still needs to be constantly improved, supplemented and adjusted. Enterprises should closely track the latest scientific and technological trends and cutting-edge technological progress, and grasp the development direction from the commanding height of science and technology
