Guo Qimin, director of the Department of Resource Conservation and Environmental Protection under the National Development and Reform Commission, revealed that restrictions on the use of spare parts and raw materials for automobile remanufacturing will gradually be released. The government will no longer impose restrictions on the two major issues that force the scrapping of auto parts and the import of scrap parts and components.
The remanufacturing of auto parts and components refers to the mass production of professionally rehabilitated used auto parts, engineering machinery, machine tools, etc. The remanufactured products achieve the same quality and performance as the original new products. Compared with manufacturing new products, remanufacturing can save energy by 60%, save materials by 70%, and save costs by 50%.
1. The matrix reinforcement materials are used at the detailed nodes to strengthen the strength and tensile crack resistance of the waterproof layer. In case of deformation and crack at the pipe root, internal and external corners, gutter and other detailed nodes due to the unsynchronized settlement and structural temperature deformation, the leakage caused by the damaged coating can be prevented.
2. On the one hand, the tensile strength of the waterproof coating can be enhanced by paving the matrix reinforcement material in a large area to make up for the low tensile strength of the waterproof coating itself; On the other hand, it can also improve the uniformity of waterproof film thickness. When the waterproof coating is applied on a large area, due to the presence of matrix reinforcement materials, sufficient materials must be loaded as required, and the loading must be evenly spread, otherwise the matrix will be soaked.
