美孚拉玛500系列防锈润滑油
Mobilarma 522 ，Mobilarma 524，Mobilarma 525
产品描述
美孚拉玛500系列润滑油是优质性能的产品，主要用于运行或将润滑油，并提供有效的防锈膜对机械内部表面。他们特别适合在柴油和汽油发动机的润滑油中运行。油驱水从金属表面形成强的防水膜，在金属表面，防止生锈和腐蚀。在拉玛系列油吸收水系统成油包水乳液使接触表面的机械仍然得到良好的润滑。其良好的化学稳定性和耐磨性和洗涤剂的性能使它们适合作为高质量润滑油水平短期。
在大多数应用中，当装配有润滑油或液压油，并在维修中重新安装时，不必冲走残留的防锈膜。然而，一个负责润滑油去除拉玛产品或其残膜冲洗，建议如果：
1。在拉玛不提供所需的润滑特性操作设备在额定负载和温度
2。设备的排水的拉玛不能和可观的口袋容易去除
三.由拉玛的系统油液的污染可降低润滑性能特点（例如；拉玛能增加氟利昂云点的油包水减少压缩机或高压液压系统的抗磨特性）
4。防锈剂的存在降低了新的石油的能力，在涡轮机和类似的设备分开的水。
应用
发动机和工业设备的油和油润滑油
长时间不使用的涡轮机
水是存在的液压系统，乳剂的形成不会影响操作

Mobilarma 500 Series
Rust Protection Lubricants
Product Description
Mobilarma 500 Series oils are premium performance products primarily intended as run-in or lay-up lubricants, which provide effective rust preventive films on the internal surfaces of machinery. They are particularly suitable as run-in lubricants for diesel and gasoline engines. The oils displace water from metal surfaces and form strong water-resistant films on the metal surfaces to prevent rust and corrosion. The Mobilarma Series oils absorb the water in systems into a water-in-oil emulsion so that the contact surfaces of the machinery still get satisfactory lubrication. Their high level of chemical stability and their anti-wear and detergent properties make them suitable as high quality short-term lubricants.
In most applications, the residual rust preventive films need not be flushed away when the assembly is filled with lubricating oil or hydraulic fluid and put back in service. However, flushing with a charge of lubricating oil to remove the Mobilarma product or its residual film, is recommended if:
1. The Mobilarma does not provide the required lubricant characteristics to operate the equipment at rated loads and temperatures
2. Draining of the equipment is difficult and considerable pockets of the Mobilarma cannot be easily removed
3. Contamination of the system oil by the Mobilarma could reduce the lubrication performance characteristics (examples; Mobilarma could increase Freon cloud points in compressors or water-in-oil emulsions reduce anti-wear characteristics in high pressure hydraulic systems)
4. Presence of the rust preventive agents reduces the ability of the new oil to separate water in turbine and similar equipment.
Features and Benefits
The Mobilarma 500 Series oils provide an excellent lubricant that also acts as a rust preventive. This allows safe lay-up of equipment that will not be used immediately but may be operated intermittently at low to moderate loads for short periods of time. These products provide excellent rust preventive performance reducing any potential damage that could otherwise occur in non-operating equipment. This saves clean-up and potential rigorous flushing procedures prior to placing the equipment back in service.
