简 介
美孚高温滑脂是以非皂基增稠剂制成之高温滑脂,专用于工业上一般滑脂无法抵受之长期高温,或温度循环变化於常温以至极高温之间的情况。本系列滑脂对因高温而引起之氧化、硬化或软化引致泄漏，有特出的抵抗能力，在潮湿的环境下，亦能防止腐蚀。美孚高温滑脂78含有二硫化钼。
优点
·对钢铁及有色金属均能提供良好的防腐蚀保护
·减低高温泄漏现象
·保持良好的低温使用性能
·与一般滑脂比较，适用之温度范围较大而使用寿命亦较长
用 途
美孚高温滑脂适用於长期操作於摄氏150度至175度的滑动轴承及滚动轴承。火炉输送带、窑车、纸厂的烘乾机及起纹机之轴承，因其温度经常循环变化於常温及高温之间，故应采用本系列滑脂。轴承内滑脂之清除、更换、及添补滑脂之频率，要视乎滑脂暴露于高温的程度而定。
性质
·应用温度范围广阔，并能维持原有之结构及硬度
能抵抗水、蒸气、温和酸性或碱性液体的冲洗
·挥发性低，减低因受高温而硬化之程度
·防蚀及抗氧化
·容易泵送

Product Descr1ption
Mobiltemp 78 grease is a non-soap thickened, high temperature greases for industrial applications where the capability of conventional greases may be exceeded by either continuous high temperature or cyclic conditions ranging from normal to extremely high temperatures. It is remarkably resistant to high temperature oxidation, to high temperature hardening or softening (and subsequent leakage) and provide
good protection from corrosion in humid atmospheres. Mobiltemp 78 contains Molybdenum Disulfide.
Benefits
· Provides good corrosion protection for both steel and non-ferrous metals
· Minimizes leakage at high temperature
· Maintains good low temperature dispensability
· Provides longer service life over a wider temperature range than conventional greases
Application
The Mobiltemp 78 grease is recommended for the lubrication of plain and antifriction bearings operating continuously in the 150 ℃ to 175 ℃ range or under conditions where bearings are repeatedly cycled from normal ambient temperatures to the range encountered in equipment such as oven conveyors, kiln car bearing and paper mill dryers and corrugators. The frequency of purging and relubrication of bearings is a function of the extent of exposure of the grease to high temperature and can only be determined on a case by case basis.
Properties
· Highly resistant to changes in structure and consistency over a wide temperature range
· Resistant to washout by water, steam and mild acidic or alkaline washes
· Exhibit low volatility to minimize hardening at high temperature
· Corrosion and oxidation inhibited
· Good pumpability
