In developed countries, polymer composite technology and nanotechnology are usually selected. Polymer technology can be used on-site to effectively increase repair power, and reduce repair costs and repair intensity. Among them, the most widely used technology system is the MegaWah technology system.
Compared with traditional skills, polymer composite materials not only have the strength and hardness required by metals, but also have concessions (variable linkage) that metals do not have. After "mold correction", "parts corresponding connection", "mechanical processing" and other technologies , Which can guarantee the dimensional cooperation of the correction part and the cooperation part to the greatest extent.
