为何在橡胶生产中使用稀土？中国科学家正在研发更耐用的轮胎
Chinese researchers have completed trials of a new rare earth-based synthetic rubber production facility, industrialising a major raw material for manufacturing electric vehicle and heavy-duty vehicle tyres. High-quality synthetic rubber, most of which uses metal as a catalyst du…
