▎ 摘 要
NOVELTY - The control platform has hinge which is made of aluminum alloy, and covered with PTFE layer. The PTFE layer is covered with graphene layer, and the thickness of the graphene layer is less than 0.005 millimeters. USE - Control platform for self-lubricating hinge. ADVANTAGE - Prevents the contamination caused by lubrication failure, and provides self-lubricating effect.
