簡 介
美孚滑脂XHP 222 特級是 ISO 粘度等級2 2 0 ,NLGI2號含有二硫化鉬之極壓高級滑脂。美孚滑脂222特級采用高品質的復合鋰皂基結合具極高粘性的聚合物制造而成。這不單使此產品在嚴荷的工作環境下， 仍然不會軟化，并有超卓的粘附性能，使在工作溫度界乎20OC至150OC(–4至3 0 0 O F )之間， 維持硬度一致。本滑脂的抗拋脫能力和密封特性亦非常優良。美孚滑脂 XHP 222 特級含有百份之0.75微細形的二硫化鉬。此二硫化鉬可粘附在金屬表面形成保護薄膜， 減低摩擦系數。在邊界潤滑情況下， 這薄膜配以極壓添加劑發揮防劃傷和抗磨保護。其它特性包括出色的水污染忍受性和抗高溫 氧化能力。用于換油中心的泵送設備亦有良好的泵送性。美孚滑脂XHP 222特級通過美國標準測檢方法(ASTM)之D1743 腐蝕保護測試， 對鋼和銅并沒有腐蝕作用。
用 途
美孚滑脂 XHP 222 特級可以延長添補滑脂周期， 適合推薦用在汽車底盤配件及車輪軸。此產品亦滿足船隻，農業，車隊及大型工地設備的多用途滑脂的需要。美孚滑脂XHP 222 特級主要是推薦用于經常出現滑動和振動情況的懸置軸承， 或經有關設備制造商指定含二硫化鉬的滑脂。當此產品用在客車和輕卡車的懸置球形節、重型卡車的轉向節主鎖和拖架的轉盤時， 都能長期保持有效的潤滑油膜使操縱更容易。
Product Descr1ption
Mobilgrease XHP 222 Special is an ISO Grade 220, NLGI No. 2, molybdenum disulfide fortified, extreme-pressure premium grease. Mobilgrease XHP 222 Special is formulated with a high quality lithium complex soap thickener and a special high-tack polymer to ensure good resistance to softening under severe working, excellent adhesion, and a uniform consistency over the recommended operating temperature range of -20°OC to 150°OC (-4°OF to 300°OF). Fling-off resistance and sealing properties are also excellent. Mobilgrease XHP 222 Special ontains 0.75% micronized molybdenum disulfide that plates-out from the grease and forms an adhering film on metallic surfaces, reducing coefficient of friction. This film and the extreme-pressure additives provide protection against scoring and wear under boundary ubrication conditions. Other formulation characteristics include superior water tolerance, high temperature oxidation resistance, and good pumpability by service station dispensing systems. Mobilgrease XHP 222 Special passes the ASTM D 1743 Corrosion Protection test and will not corrode steel or copper.
Application
Mobilgrease XHP 222 Special is an extended lubrication interval grease recommended for the lubrication of automotive chassis fittings and wheel bearings. It also performs well as a multipurpose grease for marine craft, farm, fleet, and contractor equipment. Mobilgrease XHP 222 Special is particularly recommended for heavily loaded suspension bearings where sliding or oscillation occurs, or where the equipment manufacturer specifies a grease containing molybdenum disulfide. It will maintain an effective lubricating film over extended periods and contribute to reduced steering effort when used in the suspension ball joints of passenger cars and light trucks, the kingpins of heavy trucks, and the fifth wheels of tractor trailers. | Characteristics 特 性 | 以 下 所 列 數 據 除 特 別 注 明 外， 均 為 典 型 值
