2011年10月21日,杭州 — 全球领先的包装及加工技术整线系统供应商—博世包装技术今日宣布其位于杭州经济开发区的厂房三楼正式扩建落成并启用。此次扩建项目共投资约900万人民币。扩建完成后,博世包装技术杭州工厂将新增办公面积1,400平方米,预计届时将新增员工约120名。今年恰逢博世包装技术(杭州)有限公司成立10周年,此次扩建也将标志着博世包装技术杭州厂房累计投资额突破9300万人民币,生产和办公面积突破16000平方米。
博世集团包装技术事业部总裁克莱奋 (FriedberR2001-223-90精级滑块轴承轴承1.摩擦相容性,轴径与轴瓦直接接触时防止发生粘附和形成边界润滑的性能。影响摩擦副摩擦相容性的材料因素是:
(1)成副材料冶金上构成合金的难易程度。
(2)材料与润滑剂的亲和能力。
(3)成副材料在无润滑状态下的摩擦因数。
(4)材料的微观组织。
(5)材料的热导率。
(6)材料表面能的大小和氧化膜的特性。
2.嵌入性,材料允许润滑剂中外来硬质颗粒钳入而防止刮伤或(和)磨粒磨损的能力。对金属材料而言,硬度低和弹性模量低者,嵌入性就好,而非金属材料则不一定,
