美孚Nyvac FR 200D
高性能耐火液压液
产品描述
美孚Nyvac FR 200D是一个额外的高性能水乙二醇型抗燃液压液。它是以二甘醇为主要成分配制乙二醇。该产品不含乙二醇。美孚Nyvac FR 200D提供优异的防锈和抗气相腐蚀。在液压泵测试中，它显示出高水平的抗磨性能。高粘度指数使得美孚Nyvac FR 200D有效在很宽的工作温度范围。其泡沫性、低温流动性和贮存稳定性也很好。
美孚Nyvac FR200D的耐火性能来自其含水量。即使当液喷在压力超过200 bar / 3000磅的柴油机喷油器喷嘴进入气体火焰不会燃烧，也不会当下降到熔融金属。含水量是重要的，必须保持在38%，以保持最佳的抗火性能和粘度特性。由于水的蒸发损失可以加入去离子水产品容易纠正增加黏度。这是不推荐使用的系统在散装液体温度超过65ºC.美孚Nyvac FR 200D操作兼容填料、垫片，由液压系统中常见的材料软管和蓄电池，除了由聚氨酯制成的物品，皮革或软木材料。美孚Nyvac FR 200D是通过FM Global批准。
美孚Nyvac FR 200D的广泛的应用能力和优异的性能使其在许多工业用户的首选产品。

应用
在共同与其他所有的水-乙二醇型流体，美孚Nyvac FR 200D是与一般油漆不相容。环氧树脂或酚醛树脂漆是合适的。美孚Nyvac FR 200D不应与其他类型的液体混合。虽然它是与其他水乙二醇型产品兼容，外加剂可能会减损美孚产品的属性。含水量是重要的，必须保持在38%，以保持最佳的抗火性能和粘度特性。这是不推荐使用的系统在散装液体温度超过65ºC.操作
美孚Nyvac FR 200D推荐用于所有类型的液压泵和马达靠近火源操作，提供制造商的指示进行观察。典型应用包括：
压铸机压
燃烧调节剂
炉门开启
钢包倾动机构
玻璃拉丝机械

Mobil Nyvac FR 200D

High Performance Fire-resistant Hydraulic Fluid

Product Description

Mobil Nyvac FR 200D is an extra high performance 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 FR 200D provides excellent protection against rust and against vapour phase corrosion. In hydraulic pump tests, it has shown a high level of antiwear performance. A high viscosity index makes Mobil Nyvac FR 200D effective over a wide range of operating temperatures. Its foam resistance, low temperature flow and storage stability are also excellent.
The fire-resistant properties of Mobil Nyvac FR200D arise from its water content. Even when the fluid is sprayed at a pressure of over 200 bar / 3000 psi from a diesel injector nozzle into a gas flame it will not ignite, nor will it when dropped onto molten metal. The water content is important and must be maintained at 38% to retain optimum fire resistant properties and its viscosity characteristics. Viscosity increase due to loss of water by evaporation can be easily corrected by adding deionised water to the product. It is not recommended for use in systems operating at bulk fluid temperatures above 65º C. Mobil Nyvac FR 200D is compatible with packings, gaskets, hoses and accumulators made from materials normally encountered in hydraulic systems, except items made from polyurethane, leather or cork materials. Mobil Nyvac FR 200D is approved by FM Global.
Mobil Nyvac FR 200D's wide application capability and excellent performance make it the product of choice among many industrial users.

Features and Benefits

Mobil Nyvac FR 200D is a key member of the Mobil brand of fire-resistant hydraulic fluids. Mobil Nyvac FR 200D was developed in conjunction with hydraulic equipment builders to meet the needs of moderate pressure applications where fire-resistance properties are critical, and where good lubricity and product life are also required.

Applications

In common with all other water-glycol type fluids, Mobil Nyvac FR 200D is not compatible with typical type 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-glycol type products, admixtures may detract from the properties of the Mobil product. The water content is important and must be maintained at 38% to retain optimum fire resistant properties and its viscosity characteristics. It is not recommended for use in systems operating at bulk fluid temperatures above 65º C.
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 and presses
• Combustion regulators
• Furnace door openers
• Ladel-tilting mechanisms
• Glass drawing machinery
