At the same time, in order to enhance the awareness of adiabatic energy-saving materials manufacturers to pay attention to product quality and honest management, maintain market order and brand image, and promote the high-quality and healthy development of the industry, the professional committees and branches of the China Adiabatic Energy-saving Materials Association represent the adiabatic energy-saving materials industry. The member units issued the "Proposal for the Self-Discipline Convention of the Adiabatic Energy-saving Materials Industry".

Since the beginning of this year, with the proposal of the "double carbon" goal, carbon peak and carbon neutrality were included in the government work report for the first time at the National Two Sessions, which became a "hot word" discussed by the delegates ". In fact, the term "carbon peak and carbon neutral" stems from China's commitment to the international community at the general debate of the 75th UN General Assembly on September 22 last year. It was pointed out at the meeting that China will increase its nationally determined contribution and adopt more powerful policies and measures. Carbon dioxide emissions will strive to reach a peak by 2030 and strive to achieve carbon neutrality by 2060. According to the plan, it can be predicted that carbon peak and carbon neutrality will be the major theme of China in the next 5 to 10 years. The convening of the industry innovation conference aims to promote the healthy development of the insulation energy-saving industry, give full play to the advantages of insulation energy-saving materials, and contribute to the industry's strength for the goal of carbon peak and carbon neutrality. At the meeting, dozens of industry experts and scholars gathered together to focus on the innovation and development of the industry, which is of great significance to promote the green and low-carbon development of the industry.

In view of the development goal of "double carbon" in the adiabatic energy-saving industry, Yue Quanhua, director of the building materials department of the raw materials industry department of the Ministry of industry and information technology, said that adiabatic energy-saving materials are an important part of the building materials industry and a supporting material for building energy conservation and industrial energy conservation, which is of great significance for China to achieve the goal of "double carbon. Under the background of carbon peak and carbon neutrality, adiabatic energy-saving materials should seize the development opportunities, coordinate the industry strength, continuously increase technological innovation, promote the research and development of common technologies for carbon saving in production and application, improve the standard system, carry out pilot demonstrations, and strive to make due contributions to China's goal of carbon peak and carbon neutrality.

opportunities and challenges

The Fifth Industry Innovation Conference upholds the concept of "innovation to enhance low-carbon peak consensus and high-quality development". From the theme of the conference, it is not difficult to see that carbon reduction, innovation and high-quality development will become the survival and development path of the insulation energy-saving materials industry. According to Kong An, vice president of China Building Materials Industry Planning and Research Institute, with the proposal of the national "double carbon" goal, the thermal insulation and energy-saving industry will encounter the following opportunities: thermal insulation and energy-saving materials will become a driving industry to realize green development in an all-round way; the application of thermal insulation and energy-saving materials to building thermal insulation and energy-saving accounts for more than 80% of the total consumption; (Take rock wool as an example) the energy saving benefit and emission reduction benefit are 100 and 200 times of their own consumption respectively. Parallel to the opportunities, there are challenges, and the industry will also encounter the following challenges: on the one hand, the national standards and requirements for building energy conservation are increasing year by year, and now the energy-saving standards in many areas have gradually developed from 75% to 80%, or even higher. This puts forward more requirements for the performance and dosage of thermal insulation energy-saving materials; on the other hand, the pressure of thermal insulation energy-saving materials in the domestic new production capacity and existing production capacity will be further increased. From the layout, project approval, energy use and other aspects are facing important challenges in policy.

At the same time, Kong An also said that under the strategic deployment of the "double carbon" target, the main tasks of the adiabatic energy-saving materials industry are from the industry level, including highlighting the role of the application of adiabatic energy-saving materials in various industries in achieving the "double carbon" target. Technology and process improvement, energy substitution; Further optimization of products and industrial systems; From the enterprise level, it is necessary to accelerate the energy-saving and low-carbon transformation of enterprise production processes; accelerate the adoption of carbon capture, utilization and storage (CCUS) technologies.

path and countermeasure

According to relevant statistics, the construction industry consumes about 30% to 40% of the world's energy and emits almost 30% of the world's greenhouse gases. If the building energy efficiency is not improved and the building energy and carbon emissions are reduced, the construction industry's greenhouse gas emissions will account for more than 50% of the total emissions by 2050.

Sun Shibing, a professor at Beijing University of Technology, said that for the insulation energy-saving materials industry, the path of "double carbon" target participation mainly focuses on its own development and application development. Self-development includes improving the energy efficiency of products, which is an eternal theme; discovering new opportunities, developing new products and technologies; energy saving and emission reduction in production processes. Application development includes solving the applicability technology of building application, seizing the opportunity of industrial energy conservation and striving for a breakthrough, seizing the opportunity of "cold chain new format", actively participating in application development, from waiting to taking the initiative, and developing to internationalization.

There are many varieties of adiabatic energy-saving materials, many application channels and many enterprises, which determine the foundation of unity and organization. It is suggested to set up branches, special committees, groups and other forms of detailed objectives, consistent and substantive discussions and group actions, one by one, and break through from quantitative change to qualitative change one by one.

At the same time, Liu Jiagen, deputy chief engineer of Tsinghua University Architectural Design and Research Institute Co., Ltd., said that the definition of carbon emissions by China's construction department is in accordance with the national standard "building carbon emission calculation standard": building carbon emissions are calculated according to the whole life cycle -- building materials production, construction, building operation and building demolition. From the life of the whole life, the operating energy-related carbon emissions accounted for up to 70% to 90%, building materials carbon emissions of about 10% to 30%. If we consider the short cycle of building materials production and construction, and optimize it, it will contribute more to the low carbon of the construction industry.

Under the goal of "double carbon", the energy-saving standard level of new urban buildings will be gradually improved, new materials and new products of high-performance envelope structure will be gradually developed and launched, and energy-saving transformation of existing residential buildings will also be accelerated.

survival and development

With the recent introduction of policies to restrict thin plastering systems in Shanghai, Chongqing, Jiaxing, Hebei, Xinjiang and other places, the survival and development of building exterior insulation has reached a "crossroads". Bao Yuqing, deputy director of the Beijing Building Energy Conservation Research and Development Center, emphasized that over the past 30 years, building energy conservation work has continued to develop from the north to the south, from residential to public construction, and from towns to rural areas, especially in severe cold and cold areas. With the implementation of the "four-step" energy-saving standards, on January 1 this year, Beijing took the lead in implementing the 80% energy-saving standard, and the depth and breadth of building energy-saving are in the country, remarkable results.

Bao Yuqing said that with the improvement of building energy-saving standards, insulation projects have become the most important wall insulation technology in severe cold areas. After investigation, it is found that in the foreseeable future, external wall insulation will still be the main form of external wall insulation in cold and cold areas. However, due to various considerations, it is still possible that some regions will issue ban policies in the near future. At the same time, different regions will have different emphases on wall insulation policies. In severe cold regions, some external insulation methods will be mainly restricted.

In recent years, engineering accidents have occurred in low-cost and inferior exterior insulation projects, and fires, shedding and water leakage have occurred from time to time. Relevant functional departments have doubts about the reliability and durability of thin plastering exterior insulation systems. The root of the problem is that the industry and enterprises have a large deviation in understanding the importance and safety of the safety and quality of exterior insulation systems. The industry and enterprises should deeply reflect on their own problems and shortcomings, and in the future development of effectively improve these problems and deficiencies, to create a safe, healthy and harmonious environment for the society. At the same time, we see thin plastering exterior wall insulation technology in Europe and the United States has nearly 60 years of development, rock wool thin plastering exterior wall insulation system has nearly 50 years of engineering practice, has been proved to be an effective and reliable technology and process in the building envelope. In China, the earliest EPS thin plastering exterior insulation system has been more than 28 years, and it is still in normal use, and the insulation system is in good condition. This shows that under the premise of ensuring the quality of materials and construction quality, thin plastering exterior insulation technology is mature and reliable.

Thinking and coping

On April 12 this year, a media in Henan published "Vigorously develop green building materials to put on safe and energy-saving" cotton clothes "for buildings-Zhang Yumin, deputy to the Provincial People's Congress and deputy director of the Financial Budget Working Committee of the Standing Committee of the Henan Provincial People's Congress, talked about the province's construction projects. Prohibit the use of rock wool insulation products. The views mentioned in the article, such as "it is recommended to speed up the ban on the use of rock wool insulation products in Henan Province," have aroused great concern in the insulation and energy saving industry.

In response to this article, the China Insulation Energy-saving Materials Industry Association organized relevant units to hold a video conference for the first time. Through this incident, the rock wool industry crisis into an opportunity, under extensive discussion and demonstration, not only to achieve the development of the standardized industry, but also to promote the high-quality development of the industry.

Han Jixian pointed out that it is necessary to have a clear understanding of the outstanding common problems such as fire prevention, cracking, and shedding of the current external wall insulation system. In order to improve themselves, research and development of new technologies, new processes, from the system to seek insulation energy-saving material solutions involving the whole life cycle, transformation and upgrading to promote the high-quality development of the industry.

Liu Chun, deputy general manager of Sinoma Science and Technology Engineering Company, said that China's rock wool production reached 3.8 million tons in 2020, up 26% year-on-year. Under the promotion of environmental protection policy, the industry upgrade and integration. But at the same time, there is also shoddy and low-cost competition in the industry, which has a negative impact on the industry. In the process of using rock wool, according to the production capacity of 3.8 million tons, it is estimated that 3.3 million tons will be used in construction and 500000 tons in industry. If the annual consumption of standard coal can be reduced by 499.8 tons in construction, it can be converted to the whole industry, and the annual consumption of standard coal can be reduced by 14.5 million tons, which is a real energy-saving effect.

From the "double carbon" background, there are some voices in the recent public opinion that rock wool production energy consumption is higher, in fact, rock wool itself is an energy-saving product, in the process of production, how to reduce their own production energy consumption through technological innovation, collaborative processing, to deal with the development requirements of the "double carbon" goal is the most critical. In terms of specific paths, it mainly includes low-carbon power grid production line technology, solid waste co-processing technology, solid waste return technology, and intelligent logistics. The future industry needs to be based on scientific research and innovation, research and development of efficient collaboration, to achieve their own high-quality development.

Zhang Jianhong, assistant to the general manager of Nanjing Guocai Testing Co., Ltd. and director of the thermal insulation material testing center, said that the main application parts of building energy conservation include roof insulation, wall insulation, ground insulation, indoor partition wall insulation and basement moisture-proof insulation. At present, the most widely used is mainly roof insulation and wall insulation. In the application of exterior insulation, the main forms include thin plastering and curtain wall.

The future road of rock wool for external wall insulation in China is mainly for the national energy conservation and emission reduction policy, building fire protection code, research and development of high quality rock wool products and construction supervision in place.
