Photovoltaic and wind power are one of the most favorable ways to reduce carbon emissions. my country is also the country with the most complete supporting industry chain of photovoltaic and wind power in the world. Especially at an important moment when the Ministry of Ecology and Environment is strengthening the curb on the construction of "two high" projects (high energy consumption and high emission), the thermal power industry has been focused and restricted, and photovoltaic and wind power will usher in a new round of development opportunities. Technological advancements in our adhesives and adhesive tape industries will strongly support the rapid growth of the photovoltaic and wind power industries.
In terms of market changes, we focus on the rapid growth of lightweight vehicles and new energy vehicles. Compared with traditional cars, the use of lightweight materials in cars will rise from 29% to more than 60% in the next 20 years. In addition, the amount of glue used in new energy vehicle power battery assembly bicycles (pack sealing, structural heat conduction, structural bonding, BMS protection, cell bonding, battery potting, thread locking, shell bonding, etc.) will reach about 5 kg , The sales of bicycles are about 500-1000 yuan, and the glue for automotive electronics will also be the focus of attention.
Adhesives for interior decoration materials will also undergo changes. The first is the revision of two old standards (GB18583 and GB30982). The new standards will further limit their indicators, standardize the development of the industry, and improve the quality of products.
Secondly, the prefabricated building market will continue to expand. As of the end of 2020, a total of 630 million square meters of prefabricated buildings have been newly started across the country, an increase of 50% over 2019, accounting for about 20.5% of the newly built building area. See Figure 1 for details. From the perspective of carbon emissions from energy terminals, compared with cast-in-place buildings, the construction method of prefabricated buildings can save a certain degree of carbon emissions in the production and construction stages of building materials. On the one hand, prefabricated buildings adopt an intensive and large-scale digital production mode. On the other hand, the mechanized installation method was adopted in the later stage, which greatly avoided the occurrence of construction waste, and the energy consumption was reduced by more than 20%, and the advantages of energy saving and emission reduction were obvious.
