简 介
美孚纽华FR 200D是最新一代水溶性醇类 抗燃液压油，以二甘醇为主要成分配制而 成，不含乙二醇。美孚纽华FR 200D 能提 供出色的防锈及气相腐蚀保护。在液压泵测试中，该产品表现出高水平的抗磨特性，水分的蒸发会使粘度有所升高，但添加去离子水便可很容易地恢复粘度。美孚纽华FR 200D 获美国工厂火险联盟认可为抗燃液压油。
用 途
依照制造商之指引， 美孚纽华 FR 200D推荐用于接连火源之各种类型液压泵和马达。可用于： 印模铸压机， 燃烧调节器，火炉门打开器、钢包倾斜机构和玻璃抽拉或成型机等。美孚纽华 FR 200D与液压系统中常见的填料、垫片、软管及其它填聚物相容， 但聚氨基甲酸酯、石棉、皮革和软木除外。和一般水溶性醇类一样， 美孚纽华 FR 200D是不能和典型的油漆相容。但用环氧基树脂和酚醛树脂为基础之油漆是可相容的。美孚纽华 FR 200D是不可能混和其它不同类之液体。虽然它是与其它水溶性二元醇相容， 但是混和出来的混和物会减损美孚产品之特性。
优 点
美孚纽华 FR 200D 可提供以下优点：
·出色的抗燃性能， 使人在设备工作时更安全
·如按制造商推荐使用， 可将泵、阀磨损降至最低
·防锈、抗腐蚀
·良好的低温流动性
·粘度指数高， 应用温度范围广泛

Product Descr1ption
Mobil Nyvac FR200D is a water-glycol type fire resistant hydraulic fluid. It is formulated with diethylene glycol as the main glycol component. The product does not contain ethylene glycol. Mobil Nyvac FR200D provides excellent protection against rust and against vapor phase corrosion. In hydraulic pump tests, it has shown a high level of antiwear performance. Viscosity increase due to loss of water by evaporation can be easily corrected by adding deionised water to the product. Mobil Nyvac FR 200D is approved by Factory Mutual (FM) as a fire-resistant hydraulic fluid.
Application
Mobil Nyvac FR 200D is recommended for use in all types of hydraulic pumps and motors operating close to a source of ignition, providing the manufacturers instructions are observed. Typical applications include diecasting machines presses, combustion regulators, furnace door openers, ladle-tilting mechanisms and glass drawing machinery. Mobil Nyvac FR 200D is compatible with packing, gaskets, hoses and umulators made from materials normally encountered in hydraulic systems, except items made from polyurethane, asbestos, leather or cork materials.
In common with all other water-glycol type fluids, Mobil Nyvac FR 200D is not compatible with typical paints. Epoxy or phenolic resin based paints are suitable. Mobil Nyvac FR 200D should not be mixed with other types of fluids. While it is compatible with other water-glycoltype products, admixtures may detract from the properties of the Mobil product.
Benefits
Mobil Nyvac FR200D offers the following benefits :
·Safer working conditions for people and plant by virtue of its outstanding fire-resistant properties
· Minimum pump and valve wear when used in accordance with the manufacturers’recommendations
·Good protection against rust and corrosion
·Very good low temperature fluidity
·A wide range of application because of its high viscosity index
