概述
可轻松应对极端工况的润滑油（脂）
Krytox™ XHT（极端高温）润滑油（脂）使用基础油、增稠剂和化学添加剂来产生高低粘度，适合在相当高的温度下使用。
虽然大多数石油产品会在低于 99℃ (210℉) 时开始降解，并在刚低于 -18℃ (0℉) 时变得相当粘稠，但 Krytox™ XHT 高性能润滑油（脂）的工作温度范围（-70℃ 至 360℃ [-94℉ 至 680℉]）却更加广泛。如果用于合适的冶金工况并定期进行再润滑，Krytox™ XHT 润滑脂和润滑油能够在高达 400℃ (752℉) 的温度下工作。
Krytox™ XHT 润滑油（脂）的特性和优势
除了可在极端温度下工作外，Krytox™ XHT 润滑油（脂）还具备以下特性和优势：
- 不易燃：Krytox™ 高性能润滑油（脂）仅含碳、氧和氟。因为不含氢，其既不会燃烧，也不会助燃，即便在 100% 的液态氧或气态氧中也是如此。
- 化学惰性：Krytox™ 高性能润滑油（脂）不仅具有耐氧性，而且几乎不会与所有化学物质发生反应。除了含氟量高的液体和部分超临界流体（如二氧化碳），其不溶于大多数溶剂。
- 热稳定性和氧化稳定性：通过差热分析可知，在没有空气的情况下，润滑油（脂）会在 470℃ (878℉) 左右发生劣化。在 371℃ (700℉) 的氮气环境下测试 6 小时后，Krytox™ 润滑油（脂）的中和值没有增加，粘度也未发生显著变化。空气的存在并不会大幅降低 Krytox™ 润滑油（脂）的分解点。
适合各行业使用的可靠润滑油（脂）
这些润滑油（脂）有多种等级可供选择，均具有防腐蚀、额外粘合以及非熔融性能，适用于各种具有严苛需求的行业。
这些行业包括：
- 航空航天
- 化学加工
- 制造
- 金属加工
- 石油和天然气勘探
- 纺织品制造
Lubricating oil (grease) that can easily cope with extreme working conditions
Krytox ™ XHT (Extreme High Temperature) lubricating oil (grease) uses base oil, thickeners, and chemical additives to produce high and low viscosity, suitable for use at relatively high temperatures.
Although most petroleum products begin to degrade below 99 ℃ (210 ℉) and become quite viscous just below -18 ℃ (0 ℉), Krytox ™ The working temperature range of XHT high-performance lubricating oil (grease) is wider (-70 ℃ to 360 ℃ [-94 ℉ to 680 ℉]). If used for suitable metallurgical conditions and regularly lubricated, Krytox ™ XHT grease and lubricating oil can operate at temperatures up to 400 ℃ (752 ℉).
Krytox ™ Characteristics and advantages of XHT lubricating oil (grease)
In addition to being able to operate at extreme temperatures, Krytox ™ XHT lubricating oil (grease) also has the following characteristics and advantages:
- Non flammable: Krytox ™ High performance lubricating oil (grease) contains only carbon, oxygen, and fluorine. Because it does not contain hydrogen, it neither burns nor supports combustion, even in 100% liquid or gaseous oxygen.
- Chemical inertness: Krytox ™ High performance lubricating oil (grease) not only has oxygen resistance, but also hardly reacts with any chemical substances. Except for liquids with high fluorine content and some supercritical fluids (such as carbon dioxide), it is insoluble in most solvents.
- Thermal stability and oxidation stability: Differential thermal analysis shows that lubricating oil (grease) will deteriorate at around 470 ℃ (878 ℉) in the absence of air. After testing for 6 hours in a nitrogen environment at 371 ℃ (700 ℉), Krytox ™ The neutralization value of lubricating oil (grease) did not increase, and there was no significant change in viscosity. The presence of air does not significantly reduce Krytox ™ The decomposition point of lubricating oil (grease).
Reliable lubricating oil (grease) suitable for use in various industries
These lubricants (greases) are available in multiple grades, all with anti-corrosion, additional adhesion, and non melting properties, suitable for various industries with stringent requirements.
These industries include:
- Aerospace
- Chemical processing
- manufacture
- metal processing
- Oil and gas exploration
