I was born to be useful! Innovation chain Promotes Chain Extension Iteration of Guizhou Material Industry

The development of basic materials industry is related to the quality and development potential of manufacturing industry. The "Development Plan of Basic Materials Industry in Guizhou Province in the 14th Five-Year Plan" just issued a few days ago proposes to accelerate the development of high-end, agglomeration, chain, greening and integration of basic materials industry in our province. The development of basic materials in Guizhou will be directed towards more sufficient supply, higher quality and smaller gap.
As an important carrier of the technological development of material industry in Guizhou Province, Guizhou Material Industry Research Institute has formed a technological innovation chain from applied basic research, engineering technology development, pilot test, industrial demonstration to large-scale production, which is an important technological innovation platform for the research and development and integration of key technologies of composite modified polymer materials in our province and even the whole country, and constantly promotes the basic materials from "laboratory" to "application field".
Deploy innovation chain around the industrial chain
Recently, Qin Shuhao, president of the Provincial Materials Industry Research Institute, and the team are stepping up the research on solid-state lithium battery technology-completing the integration and engineering of solid-state lithium battery technology.
Three years ago, the institute set up a research and development team for solid-state lithium batteries. "Among many solid-state battery systems, only sulfide solid-state batteries can surpass liquid lithium-ion batteries in comprehensive performance. How to improve the stability of sulfide electrolyte materials by simple process preparation, inhibit the irreversible reaction between electrolyte materials and positive and negative active substances, balance the compatibility between sulfide electrolyte materials and positive and negative electrodes and the high cost of sulfide electrolyte are the key links that restrict the industrialization process of sulfide solid-state batteries as power batteries. "
R&D personnel of the Provincial Institute of Materials are conducting experiments.
Qin Shuhao told reporters that in recent years, the research team of the Institute has focused on the development of low-cost sulfide electrolyte material batch preparation process, ultra-thin electrolyte continuous film-making process, battery system screening, and batch preparation process of 50Ah power battery. It is expected that the industrial production of solid-state lithium batteries can be realized in 2023.
According to the statistics of China Automotive Power Battery Industry Innovation Alliance, the installed capacity of power lithium batteries in China will reach a new high in 2020, reaching 63.6GWh. China’s lithium-ion batteries have a good development momentum. If solid-state lithium-ion batteries replace traditional lithium-ion batteries, there will be huge market space in the future.
"To deploy innovation chain around the industrial chain, it is a prerequisite to lock in the market demand in the selection of scientific research projects. Frequent contact with the market has kept everyone in the institute sensitive to the market prospects of scientific research results. " Qin Shuhao said frankly that since the establishment of the Provincial Materials Industry Research Institute for more than 10 years, it has performed well in the research and development of new functional materials, microporous foamed polymer materials, high-performance composite materials, functional polymer membrane materials, biodegradable polymer materials and environmental functional materials, and the scientific and technological achievements formed have been widely used in the fields of automobiles, household appliances, food packaging, building materials and so on.
Focus on the Frontier of Green Technology Innovation
Focusing on the frontier of green technology innovation is an important technical demand in the development of basic materials industry in our province. The "eat dry and squeeze out" of agricultural waste is the successful practice of the provincial material industry research institute to explore the green circular economy model. Using agricultural wastes such as straw and rice husk as raw materials, a bio-fertilizer containing biochar, humus and beneficial microorganisms was developed, and then spun into ingots, molded by poly-plastic, and manufactured into finished products.

"These fertilizers contain certain mineral nutrients, which can improve soil water and fertilizer conservation performance and improve soil nutrient status. Taking pepper as an example, it can increase its yield by more than 15%". In the lobby on the first floor of the Provincial Materials Industry Research Institute, Wu Xiao, the head of the Research Institute’s Achievement Transformation and Technical Service Center, showed reporters the biochar series products that have achieved 100 mu demonstration in many places in the province.
Reduction, harmlessness and resource utilization. The research institute proposed that agricultural wastes should be returned to the fields to improve the soil through the technology of "biochar+organic fertilizer compounding", and the demonstration research on the integration and application of biochar surface properties, pore structure regulation, metal oxide loading, microbial loading and organic fertilizer compounding technology was carried out, so as to develop carbon-based organic fertilizer and other environmental functional materials suitable for different crops. "It has the effects of improving soil organic matter content, reducing the amount of chemical fertilizer, promoting the growth of plant roots, improving crop quality and reducing the occurrence of crop diseases and insect pests. By converting straw into biomass charcoal, carbon dioxide in the atmosphere can be captured and converted into carbon and fixed in the soil, effectively increasing the soil carbon pool and offsetting the carbon emissions caused by economic development. " Wu Xiao said.
Located in Wawu Village, Bijiang District, tongren city, the application demonstration site of biomass carbon materials.
Under the background of "peak carbon dioxide emissions, Carbon Neutralization", with the continuous improvement of technical level and the deepening of environmental protection concept, the preparation technology of high-performance biodegradable polymer materials and environmental functional materials possessed by Provincial Institute of Materials Industry is welcoming new development opportunities. Wu Xiao said that the development layout of the research institute focuses on the development opportunities of biomaterials under the background of "double carbon". In order to accelerate the application of related products in the terminal field, the Provincial Materials Research Institute is working closely with Guizhou Guifu Fungus Industry Development Co., Ltd., Guizhou Delicious Fresh Dictyophora Industry Co., Ltd., Guizhou China Tobacco Industry Co., Ltd. and Guizhou Vegetable Group Packaging Materials Co., Ltd. to develop biodegradable plastic films, modified atmosphere films, reusable shopping bags and other packaging products.
　Deep integration of Industry-University-Research
"Cooperate with Geely Automobile in the development and industrialization of injection molding application technology for micro-foamed automobile interior parts, provide them with lightweight solutions, and realize the development technology of series automobile interior parts. At the same time, through the selection of raw materials, special VOC adsorbents, special production equipment and process treatment, the residue of harmful gases in the base material is reduced. " Qin Shuhao told reporters that the Provincial Institute of Materials Industry has accelerated the construction of an innovative system with deep integration in Industry-University-Research, and provided full-chain, open-ended sharing services focusing on R&D and design for materials-related enterprises and innovative entrepreneurial teams.

In recent years, the Provincial Institute of Materials has successively established provincial-level dual-innovation demonstration bases, provincial-level creative spaces, municipal-level technology transfer centers and demonstration bases for the transfer and transformation of scientific and technological achievements, Anshun National High-tech Zone Research Center of National Composite Modified Polymer Materials Engineering Technology Research Center, and Guizhou Functional Polymer Materials Innovation Center (hereinafter referred to as the Innovation Center) to unite universities, research institutes and enterprises closest to the market with scientific and technological innovation resources, focus on the needs of industrial development, tackle key technical problems common to the industry, and push industrial development towards high quality.
In the way of "company+alliance", Guizhou Functional Polymer Materials Innovation Center has established product linkage mechanism and collaborative innovation mechanism, and formed a product research and development and production system oriented to high-end market demand.
Through the close cooperation and joint research of upstream and downstream enterprises in the industrial chain, and making full use of the advantages of technology, achievements, talents and equipment in the field of new materials, the resources of production enterprises in product pilot, industrial application, technology promotion and capital have opened up the division and barriers of innovative elements such as technology, achievements, talents, capital, equipment and application.
Industry-University-Research’s platforms are constantly emerging, and innovative achievements emerge one after another. At present, the Provincial Materials Research Institute has reached more than 200 cooperation projects with experts and teams in and outside the province, and cooperated with more than 200 enterprises in and outside the province, such as SAIC-GM-Wuling Automobile Co., Ltd. and Shanghai Volkswagen Co., Ltd., to realize the transformation and promotion of scientific research results.
"The research institute will focus on improving the industrial innovation ability, vigorously promote the integration of science and technology and economy, and build a four-in-one full-chain platform of’ technology development-achievement transformation-enterprise incubation-industrial cultivation’ to realize the organic combination of technology research and development, achievement transformation and industrialization."

The ＂super long winter vacation＂ will be over. Do you still need to do nucleic acid at the beginning of the new semester？ Multi-site announcement plan

　　With the arrival of the Lantern Festival, the "long winter vacation" is coming to an end. Do you still need to do nucleic acid at the beginning of the new semester? Many places have recently announced corresponding plans, with different details.

　　"Fuzhou Daily" WeChat WeChat official account news, on the morning of February 4, the Education Working Committee of Fuzhou Municipal Committee and the Municipal Education Bureau held a meeting on the deployment of Fuzhou’s education system in the new semester. The meeting stressed that we should accurately understand the new situation of epidemic prevention and control and the requirements of health and safety first, and firmly hold the bottom line of campus safety.

　　First, we should not relax our awareness of risk prevention. The focus of China’s prevention and control work has shifted from "preventing infection" to "protecting health and preventing severe diseases", and "Class B and Class B management" has been implemented. However, schools, teachers and students are still the key places and people for prevention and control. All local schools should stay awake and continue to do a good job in the prevention and control of epidemic situation and health on campus in accordance with the relevant spirit and prevention and control guidelines of their superiors.

　　The second is to optimize the implementation of epidemic prevention and control measures. We should seriously prepare for going back to school. Before returning to school, organize teachers and students to do self-health monitoring. If there are symptoms such as fever, dry cough, fatigue, sore throat, etc., antigen or nucleic acid detection should be carried out. If the results are abnormal, they must truthfully report to the school and delay returning to school. Before the start of school, all schools should carry out a comprehensive and thorough campus sanitation rectification and disinfection, and reasonably reserve epidemic prevention materials and medicines. To adjust the optimal detection strategy. The school no longer carries out nucleic acid screening for all staff, and teachers and students do not need to provide nucleic acid certificates when entering and leaving the school gate and campus public areas. When the epidemic is not prevalent, the off-campus personnel will no longer check the nucleic acid certificate when they enter the school; When the epidemic is prevalent, it is necessary to cooperate with the local health department to properly dispose of it according to the norms.

　　The third is to tighten the campus security string at all times. Schools around the country should further compact the responsibility of compaction safety, focus on the weak links and risk points of campus safety, and strengthen the investigation and rectification of potential safety hazards; Cooperate with public security departments to carry out special actions to protect the school, implement the guard duty and inspection system, and improve the campus safety protection conditions; Implement the normalized work of eliminating evils, carry out special rectification against bullying, and strictly observe school rules and regulations; Implement the safety education and training system, carry out emergency evacuation drills regularly, and improve the emergency avoidance ability of teachers and students; Regularly investigate the hidden dangers of school buildings and ancillary facilities, and immediately rectify the problems found in the investigation, especially the problems found in campus safety protection facilities.

　　The meeting also called for an accurate understanding of the complexity of students’ mental health problems and the adaptation problems brought about by the "long winter vacation", and a good mental health education and various teaching arrangements.

　　The above-mentioned meeting in Fuzhou mentioned that according to the latest requirements of the Ministry of Education and provincial offices, all primary and secondary schools are not allowed to organize any form of centralized examination within two weeks after the start of school. According to the requirements of the higher authorities, the quality inspection examination time for Grade Three and Grade One will be appropriately postponed to the third week of February.

　　According to Zhejiang media reports, on February 6, Hangzhou primary and secondary schools will soon usher in a new semester. In the past two days, many primary and secondary schools and kindergartens in Hangzhou have issued school opening notices, asking parents and students to prepare for school opening in advance. Many schools have mentioned the health monitoring in the week before the start of school. One week before the start of school, students carry out health self-tests such as measuring body temperature and observing clinical symptoms related to COVID-19 infection every day at home. Symptoms such as fever, dry cough, fatigue, sore throat, etc. should be tested for antigen or nucleic acid, and the Fill-in Form of Health Abnormality should be truthfully filled out. If the test result is positive, delay returning to school.

　　Some schools also mentioned that an antigen or nucleic acid test should be done the day before school starts; If there are symptoms such as fever, dry cough, fatigue, sore throat, etc., antigen or nucleic acid test should be carried out in time, and the Health Abnormality Fill Form should be truthfully filled in and reported to the school. If the test result is positive, the school will be delayed.

　　Shaoxing is also required to provide negative proof of nucleic acid. On January 30th, Yue Niu News learned from the Education and Sports Bureau of Shengzhou City, Shaoxing City that the end time of winter vacation is February 5th. If there are no special circumstances, primary and secondary school (kindergarten) students will start classes on February 6th, and the summer vacation time in 2023 is initially set as July 3rd.

　　In the past two days, many primary and secondary schools and kindergartens in Shaoxing have issued notices, asking parents to fill out the "Student Health Punch" in advance, including providing negative proof of nucleic acid, and prepare for school.

　　Ningbo media reported that on February 8, Ningbo primary and secondary schools are about to usher in a new semester. Ningbo Haishu Foreign Language School and Ningbo No.15 Middle School have started to check the health situation to ensure the safe start of school. Ningbo Haishu Foreign Language School began to check the teachers’ health and return to Ningbo, and the class teacher learned about the students in the class to ensure the safe start of school.

　　According to Jinhua Daily, in the past two days, some schools in Jinhua City have issued school opening reminders, asking parents and students to prepare for school opening in advance, and fill out the Health Monitoring Form for School Opening in Spring of 2023 as required, reminding them to detect antigens or nucleic acids in time if they have symptoms such as fever, dry cough, fatigue and sore throat. If the test results confirm that they are infected with the virus, they must truthfully report to the school, delay returning to school and not go to school to study with illness.

　　Earlier, Jinhua Education Bureau released a message on January 18th, requesting that teachers and students should do a good job of daily home health monitoring seven days before the start of school. Health monitoring was carried out for 7 consecutive days after teachers and students returned to school to reduce the gathering of people. Primary and secondary schools (kindergartens) carry out nucleic acid detection such as teacher-student screening, rotation inspection and sampling inspection according to the epidemic situation and the actual situation of the school, but it is not used as a certificate for teachers and students to enter and leave the school gate.

　　Recently, official website, National Health Commission, released a message, and the comprehensive group of joint prevention and control mechanism in the State Council issued the Operational Guidelines for the Prevention and Control of Infection in novel coronavirus, among which the Operational Guidelines for the Prevention and Control of Infection in novel coronavirus in Schools put forward specific requirements for the prevention and control of epidemic situation in campus.

　　The "Guide" requires that schools without epidemics carry out normal offline teaching activities. During the epidemic peak, primary and secondary schools and kindergartens adopt strict closed management, and colleges and universities can implement district management. When teachers and students have symptoms such as fever, dry cough, fatigue and sore throat, they don’t come to school to work or study with illness. If the test results confirm that you are infected with the virus, you must truthfully report to the school and delay returning to school. The temperature of teachers and students was measured when they entered the school. The school places common disinfection products at the entrance of the school building, the entrance of the stairs, the entrance of the elevator, etc., and the dining table in the canteen is equipped with partitions, so that students can eat at different peaks. Reduce the class size appropriately and increase the distance between desks and chairs. Refine the grading diagnosis and treatment methods of infected people in schools, and reserve symptomatic treatment drugs, antigen detection reagents and commonly used epidemic prevention materials for novel coronavirus infection in schools at all levels. Do not organize teachers and students in rehabilitation period to participate in strenuous exercise.

　　The Guide makes it clear that colleges and universities will no longer carry out all-staff nucleic acid screening. Unless it is really necessary to go back to school across regions, teachers and students in colleges and universities are not required to provide nucleic acid certificates when they enter and leave the school gates and campus public areas. University hospitals set up fever clinics and implement a 24-hour duty system. Teachers and students in primary and secondary schools and kindergartens will no longer provide nucleic acid certificates when they enter and leave the school gate. When the proportion of infected people is relatively large, they can stop offline classes and implement online teaching in class or grade. At the same time, implement the morning and afternoon inspection system, the epidemic reporting system of infectious diseases, and the tracking registration system for absenteeism due to illness.
