As lifetime lubrication is required, all functional properties, in particular ageing stability and friction characteristics, must be available at all times.
全寿命润滑是需要的,所有的性能特别是抗老化稳定性和摩擦特性必须在全寿命内有效。
The effects of IPA and DTG additions on thermal properties of chips and thermal shrinkage and ageing stability of fibers were studied.
