Mobil Nyvac FR 200D
高性能抗燃液壓油
產(chǎn)品簡介
Mobil Nyvac FR 200D 是一種性能極為出色的水-二醇型抗燃液壓油。 其配方以二甘醇為主要二醇成分。 產(chǎn)品中不含乙二醇。 Mobil Nyvac FR 200D 提供出色的防銹和防汽相腐蝕保護。 在液壓泵測試中，該產(chǎn)品顯示具有高水平防磨損性能。 Mobil Nyvac FR 200D 因其高粘度指數(shù)而可有效地用于各種作業(yè)溫度條件下 。 抗泡性、低溫流動性和儲存穩(wěn)定性也非常出色。
Mobil Nyvac FR200D 的防火特性來自其含水量。 即使將該液壓油從柴油注射器噴嘴以超過200 bar / 3000 psi 的壓力噴灑到天然氣火焰上，也不會起火；如果將其滴到熔融金屬上也不會起火燃燒。 含水量至關(guān)重要，必須保持在38%以獲得最理想的防火特性及其黏度特性 。 因蒸發(fā)失水而引起的黏度增高，可透過在產(chǎn)品中加入脫離子水來改正。 該方法不宜用於在整體液體溫度超過65 oC下運行的系統(tǒng)。 Mobil Nyvac FR 200D 與用液壓系統(tǒng)中常見材料製成的填料、墊圈、軟管和蓄能器相容，但用聚氨酯、皮革或軟木材料製成的部件除外。Mobil Nyvac FR200D 有 FM Global 保險公司的認(rèn)可。
Mobil Nyvac FR 200D 廣泛的應(yīng)用能力和出色的性能使該產(chǎn)品成為許多工業(yè)用戶的首選。
特性與優(yōu)點
Mobil Nyvac FR 200D 是Mobil 品牌抗燃液壓油系列的主要產(chǎn)品。 Mobil Nyvac FR 200D 系與液壓設(shè)備制造廠商聯(lián)合開發(fā)，以滿足耐火特性至關(guān)重要，并要求良好潤滑性及產(chǎn)品壽命的中度壓力應(yīng)用需求。

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
