九江都昌三汊港镇壳牌液压油-导热油代理1、粘度性能的不同：46号比68号的粘稠度稀些，如果是冬天的会要用粘度稀点的，便于循环流通，夏天气温高相对用粘度大点的。
2、倾点温度不同：46号液压油的倾点温度为-18℃。68号液压油的倾点温度为-17℃。
3、用途不同：46号抗磨液压油由精选含锌抗磨剂、抗泡剂调配而成的中度极压抗磨液压油，专门开发应用于液压传动和控制系统。68号抗磨液压油是抗磨损液压油，用于满足液压设备之各种需要。1, viscosity performance: 46 than 68 viscosity thinner, if it is winter will use viscosity thinner, easy circulation, summer temperature high relative with viscosity big point. 2. Different pour point temperature: the pour point temperature of No. 46 hydraulic oil is -18 ° C. The pour point temperature of No. 68 hydraulic oil is -17 ° C. 3. Different uses: No. 46 anti-wear hydraulic oil is a medium extreme pressure anti-wear hydraulic oil, which is specially developed for hydraulic transmission and control system. No. 68 anti-wear hydraulic oil is a high-performance anti-wear hydraulic oil, used to meet the needs of hydraulic equipment.
