RENOLIN ZAF D 锌和灰分，液压油清洁剂 锌和灰分液压油不断得到普及，在过去的几年里。在许多情况下，使用一个无锌液压油是必须的，特别是在工具机，液压油可以污染其他功能性流体。 液压油是锌和灰分液压油具有良好的洗涤性能。清洁剂在这些油减少形成的残留物和老龄化的副产品。 他们是液压油符合标准6743-4但更多的洗涤剂和分散剂的特点。 *重要的特点renolin南非液压油： 良好的氧化安定性和良好的抗老化 强大的极压性能和很好的抗磨损 良好的腐蚀保护 快速的空气释放性和低泡沫 良好的污泥运输和清洁性能 良好的兼容性与密封材料 应用程序： renolin南非产品是高档液压油符合标准6743-4可用于所有液压系统也为纵横润滑油符合标准6743-6。renolin南非产品含有添加剂，避免形成的残留物，保证功能机械设备可靠性分析。 | OLIN ZAF | | 32 D | 46 D | 68 D | | | Hydraulic oil type | | | | | | | acc. to ISO 6743-4 | | HM 32 | HM 46 | HM 68 | | | acc. to DIN 51 502 | | HLPD 32 | HLPD 46 | HLPD 68 | | | Lubricating oil type | | | | | | | acc. to ISO 6743-6 | | CKC 32 | CKC 46 | CKC 68 | | | acc. to DIN 51 502 | | CLP 32 | CLP 46 | CLP 68 | | | Characteristics | Unit | | | | Test method | | Colour | | 1 | 1 | 1 | ASTM D 1500 | | Kinematic viscosity | | | | | | | at 40 °C | mm²/s | 32 | 46 | 68 | ASTM D 445 | | at 100 °C | mm²/s | 5.4 | 6.9 | 8.6 | ASTM D 445 | | Viscosity index | | 100 | 105 | 97 | ASTM D 2270 | | Density at 15 °C | kg/l | 0.878 | 0.882 | 0.884 | ASTM D 1298 | | Flash point, Cleveland open cup | °C | 210 | 230 | 230 | ASTM D 92 | | Pour point | °C | -33 | -27 | -24 | ASTM D 97 | | Neutralization number | mg KOH/g | 0.35 | 0.35 | 0.35 | ASTM D 974 | | Saponification number | mg KOH/g | 1.1 | 1.1 | 1.1 | ASTM D 94 | | Air release at 50 °C | min | 3 | 4 | 7 | ASTM D 3427 | | Foaming, | | | | | | | seq.
