目前,由于石油化学工业的发展,高品质的润滑油不断涌现,进口润滑油国产化大有水到渠成之势。加之,企业对经济效益的不断追求,使润滑油油品更换成为不可避免。 1.指标对照:以被更换油品的指标为基准,比较新油品的质量指标。根据实践经验主要对照的指标有:粘度,粘度指数,P_B值和P_D值等。 2.混兑试验:混兑试验包括两方面。 ①混水试验。由于各地水质的不同,使得要求新油品应该有与当地水质较好的相容
At present, due to the development of petrochemical industry, high-quality lubricants continue to emerge, the localization of imported lubricants great potential. In addition, the continuous pursuit of economic efficiency of enterprises, so that the replacement of oil products become inevitable. 1. Index control: the index of the oil to be replaced as a benchmark, the new oil quality indicators. According to the practical experience of the main control indicators are: viscosity, viscosity index, P_B value and P_D values. Mixing test: Mixing test includes two aspects. ① mixed water test. Due to the different water quality around, making the request of the new oil should have better compatibility with the local water quality
