美孚Nyvac FR 200D
高性能耐火液壓液
產(chǎn)品描述
美孚Nyvac FR 200D是一個額外的高性能水乙二醇型抗燃液壓液。它是以二甘醇為主要成分配制乙二醇。該產(chǎn)品不含乙二醇。美孚Nyvac FR 200D提供優(yōu)異的防銹和抗氣相腐蝕。在液壓泵測試中，它顯示出高水平的抗磨性能。高粘度指數(shù)使得美孚Nyvac FR 200D有效在很寬的工作溫度范圍。其泡沫性、低溫流動性和貯存穩(wěn)定性也很好。
美孚Nyvac FR200D的耐火性能來自其含水量。即使當液噴在壓力超過200 bar / 3000磅的柴油機噴油器噴嘴進入氣體火焰不會燃燒，也不會當下降到熔融金屬。含水量是重要的，必須保持在38%，以保持最佳的抗火性能和粘度特性。由于水的蒸發(fā)損失可以加入去離子水產(chǎn)品容易糾正增加黏度。這是不推薦使用的系統(tǒng)在散裝液體溫度超過65oC.美孚Nyvac FR 200D操作兼容填料、墊片，由液壓系統(tǒng)中常見的材料軟管和蓄電池，除了由聚氨酯制成的物品，皮革或軟木材料。美孚Nyvac FR 200D是通過FM Global批準。
美孚Nyvac FR 200D的廣泛的應(yīng)用能力和優(yōu)異的性能使其在許多工業(yè)用戶的首選產(chǎn)品。

應(yīng)用
在共同與其他所有的水-乙二醇型流體，美孚Nyvac FR 200D是與一般油漆不相容。環(huán)氧樹脂或酚醛樹脂漆是合適的。美孚Nyvac FR 200D不應(yīng)與其他類型的液體混合。雖然它是與其他水乙二醇型產(chǎn)品兼容，外加劑可能會減損美孚產(chǎn)品的屬性。含水量是重要的，必須保持在38%，以保持最佳的抗火性能和粘度特性。這是不推薦使用的系統(tǒng)在散裝液體溫度超過65oC.操作
美孚Nyvac FR 200D推薦用于所有類型的液壓泵和馬達靠近火源操作，提供制造商的指示進行觀察。典型應(yīng)用包括：
壓鑄機壓
燃燒調(diào)節(jié)劑
爐門開啟
鋼包傾動機構(gòu)
玻璃拉絲機械

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
