<b>on the 22nd “yangtze river economic belt building thermal insulation polyurethane summit forum”, are you ready? </b>

if you are still suffering from the problem of building insulation in hot summer and cold in winter, and you are concerned about the hot topic of “carbon neutrality and carbon peaking” recently, and you happen to be mixed up in polyurethane circle, so how can you miss the 22nd “building thermal insulation polyurethane summit forum in the yangtze river economic belt”?

polyurethane rigid foam is currently recognized as one of the best thermal insulation materials in the world. it has superior thermal insulation performance, simple construction, and excellent mechanical properties. the thermal conductivity of the insulation material is the lowest. in order to promote the promotion and use of polyurethane materials in building thermal insulation in the yangtze river economic belt, and also to allow construction companies, developers and government-related units to better understand product performance and advantages, shanghai polyurethane industry association joined hands with tiantian chemical network on on april 22, 2021, the “yangtze river economic belt building thermal insulation polyurethane application summit forum” will be held in shanghai. we sincerely invite construction units of relevant government departments of major provinces and municipalities along the river, industry scholars and experts, and upstream and nstream enterprises in the industry to jointly discuss solutions for thermal insulation of urban buildings along the river.

in terms of building insulation materials, my country has a development history of more than 20 years. moreover, certain achievements have been made in research and production, but there is still a big gap compared with developed countries. with my country’s vigorous promotion of energy conservation and emission reduction, building insulation materials will also develop rapidly.

i think the future building insulation will develop from the following aspects:

1, developing towards external wall insulation

due to the characteristics of low cost, simple construction and safety of internal thermal insulation technology, in my country’s energy-saving technology was widely used in the period when it was just beginning to develop. however, the following problems occurred during the application process: because the thermal insulation material is indoors, the indoor use area is reduced; the heat transfer coefficient of the external wall of the building is high, and the thermal bridge cannot be prevented, so that the thermal insulation effect is not obvious. with the continuous improvement of my country’s energy-saving standards, external wall insulation will become a development trend of thermal insulation materials. the advantages of external thermal insulation are mainly reflected in:

(1) external wall insulation technology can effectively eliminate the “thermal bridge” phenomenon , to reduce the phenomenon of internal wall fracture;

(2) external wall insulation materials can improve the airtightness of the entire building , but also play a waterproof effect;

(3) the external insulation not only plays a role in thermal insulation, but also it protects the main structure of the building and prolongs the service life of the main structure;

(4) the external thermal insulation technology can reduce the occupation of the indoor usable area and improve the comfort of the indoor environment.

2, developing towards lightweight

the thermal insulation performance of building insulation materials is inversely proportional to its density, and, light high-quality insulation materials can reduce the force on the structure under the action of earthquakes. therefore, with the continuous development of my country’s housing system, building insulation materials will inevitably develop in the direction of lightweight.

3, developing in the direction of green

green building materials are a direction for the development of the construction industry. greening includes greening the source of materials, greening the production and processing process, greening the use process of the product, and greening the recycling and reuse of the product after its function fails. for example, the current organic foam insulation materials use green plant fibers instead of freon as insulation materials.

4, and develop in the direction of diversification of functions.

each building insulation material has its own characteristics, such as inorganic insulation materials it has high strength and high temperature resistance, but it is not conducive to mechanized production and has a high water absorption rate; organic thermal insulation materials have excellent thermal insulation performance, but are easy to age and have low strength, and there are certain fire safety hazards. composite thermal insulation materials can well integrate organic thermal insulation materials and inorganic thermal insulation materials, give full play to their respective advantages, and make up for their respective deficiencies.

4on the 22nd of the month, spring blossoms, meet in shanghai “yangtze river economic belt building thermal insulation polyurethane summit forum”, tiantian chemical will see you soon!
