In the face of the sudden outbreak of new crown pneumonia, new materials enterprises actively carry out science and technology to fight the epidemic. Kaisheng Junheng Co., Ltd. broke through the key technology of neutral borosilicate 5.0 vaccine bottle industrialization and donated 200000 vaccine bottles to support China's vaccine research and development and production. Relying on the Key Laboratory of Special Glass Preparation and Processing in Building Materials Industry, China Building Materials Research Institute provided more than 13000 pieces of chalcogenide infrared glass and infrared lenses urgently developed. Glass fiber filter paper and biochemical detection fiber bundles developed by Nanjing Glass Fiber Research and Design Institute provide important material guarantee for epidemic prevention and control and nucleic acid detection; the "Luban universal board" product and the core technology of "whole house assembly system" produced by Beixin Group Building Materials Co., Ltd. have been successfully applied to the construction of Wuhan Square Cabin Hospital.

The new materials independently developed by our country have solved a number of key technical problems and effectively served the construction of major national projects. The composite main structure developed by Harbin FRP Research Institute has been successfully applied to the propulsion subsystem and power supply system of China's first space station and core module. Cadmium telluride power generation glass developed by Chengdu China Building Materials Optoelectronic Materials Co., Ltd. has been successfully applied to major projects such as the Beijing Winter Olympics short track speed skating hall. The low-heat cement developed by China Building Materials Science Research Institute has been successfully applied to the world's thinnest 300-meter-class arch dam of Wudongde hydropower station.

High-precision to help new infrastructure

"Economic Daily" reporter Zhu Junbi

New materials are an important component of new infrastructure, as the world's leading new materials developer and integrated service provider, China Building Materials Group in recent years to accelerate the layout of new materials research and development and industrialization development. On the one hand, we will increase investment in key technologies and research and development in the field of new materials, improve the supply and guarantee capacity of core key materials, and serve the major strategic needs of the country; on the other hand, we will adhere to the industrialization orientation, closely combine the bottlenecks encountered in the development of the group and the industry, strengthen the research on common key basic technologies, and break through the key links of industrialization.

In order to allow more high-precision materials to help new infrastructure, China Building Materials strengthens the independent protection of key basic materials, helps to enhance the core competitiveness of the country's manufacturing industry, and meets the technical needs of key materials in the field of new infrastructure.

In the aviation field, China Building Materials aims at domestic large aircraft, promotes the special application of large aircraft composite materials, and obtains the qualification of CR929 large aircraft supplier. In the field of information and communication, new materials such as low dielectric glass fiber and composite roof station developed by CNBM have overcome the bottleneck of composite connection technology, realized the application in 5G communication base station, and the comprehensive technology has reached the world's advanced level.

In the field of UHV, CNBM has developed porcelain post insulators urgently needed by national UHV projects, and has taken the lead in successfully developing the world's highest voltage grade DC ± 1100k porcelain post insulators and AC 1100kV and DC ± 800kV series UHV post insulators to support a number of national UHV transmission projects.

Application Scenarios of Cadmium Telluride Power Generation Glass and Copper Indium Gallium Selenide Power Generation Glass

In the field of new energy, China Building Materials has independently developed copper indium gallium selenium photovoltaic modules, cadmium telluride power generation glass and lithium battery diaphragms. Among them, the photoelectric conversion rate of copper indium gallium selenium photovoltaic modules has set a world record and has been successfully applied to new energy vehicles. Charging piles, photovoltaic building integration and other facilities.

In the digital age of the Internet of Everything, especially under the influence of the new coronary pneumonia epidemic, applications such as smart screens and remote online have become more popular. China National Building Materials has conquered the key technology of 8.5-generation TFT-LCD glass substrates and achieved stable mass production, achieving a "zero" breakthrough in my country's high-generation LCD glass substrates; the LCD modules developed are widely used in tablet computers, smart phones, smart wear, Smart cities and other fields.

Gypsum board, light steel keel, mineral wool sound-absorbing board and other series of products meet the high quality requirements of the Beijing Winter Olympics Olympic Village for building durability, safety, low carbon, recyclable and sustainable. Hydrogen storage materials are applied in batches to a variety of new energy vehicles for the Beijing Winter Olympics, with a designed cruising range of 630 kilometers. A new generation of dry-process flame retardant and environmentally friendly high-quality boards are used for the construction of Winter Olympics venues and mountain news centers in Yanqing competition areas; five sets of cadmium telluride power generation glass have been installed in the National Ski Jumping Center area ...... By giving full play to its comprehensive advantages in the field of new materials, CNBM has provided green products for the construction of various projects in the Beijing Winter Olympics from raw material production to construction and operation to recycling and disposal.

In addition, China National Building Materials has initiated the establishment of the largest new materials industry fund in China, driving financial capital and social capital to transform and gather high-quality new materials and scientific and technological achievements. Jointly with a number of central enterprises and scientific research institutions to build the first "double carbon" public service platform for the national raw material industry; cooperate with universities to build a national artificial crystal "mass entrepreneurship and innovation" base, which has settled in more than 20 upstream and downstream enterprises, forming a coordinated development system of the industrial chain.
