hand tools19For further technical details refer to selection chart on page 67.CHALLENGE Prevent loosening and corrosion of the cover fasteners to ensure the reliability of the gasket between the housing and coversTypical applications are fasteners for inspection cover,bearing cover and input/output flangesCause•Cover fasteners that are rusted and seized make gearbox maintenance difficult and create additional labour associated with drilling and tapping the fastener hole•Fasteners can work loose when subjected to torque,vibration,thermal expansion and shock loads18Prevent leaks between the inspection cover / bearing cover / input – output flange and housing Eliminate cut gasketsOptimize sealing performance of cut gasketsCause•The use of cut gaskets is associated with several inherent problems,such as gasket relaxation,shrinkage,extrusion,and breakage which can lead to leaksSOLUTION #121CHALLENGE20Replacing cut gaskets •Sealing of rigid flangesReplace the cut gasket and apply Loctite ®518 Flange Sealant to the flange surface of the housing •Sealing of flexible flangesReplace the cut gasket and apply Loctite ®5910 Flange Sealant to the flange surface of the housing Rigid

(cover and housing) with Loctite ®5922 non hardening Flange Sealant or Loctite ®534 hardening Flange Sealant.Note:Although Loctite ®534 is a hardening Flange Sealant,the product allows a pre-cut gasket to be positioned on a gasket surface.It holds aggressively yet still allows for repositioning of the pre-cut gasket4.Position the pre-cut gasket5.Assemble and tighten as requiredNote:Accurate re-positioning,component assembly and tightening should be handled in a continuous workflow without interruptions6.Assembly is operational after 6 hours•Eliminate gasket leaks•Eliminate corrosion and

乐泰542管螺纹密封胶
乐泰542管螺纹密封胶是气动系统密封，不污染液压系统，在轻微油渍表面上也可使用，它不含填料不会阻塞阀门或过滤系统，能够快速固化，低强度。
下面由乐泰胶水产品销售中心曼伦自动化为大家介绍一下这款产品的相关知识，帮助大家购买到正确的产品。
乐泰542管螺纹密封胶用于密封及锁固(带锥形螺纹接头的)高压液压动力系统，M36以下锥螺纹(NPT)。
以下是它的使用指南：一、装配环节1.为了获得优秀效果，使用乐泰清洗剂清洗材料内外表面，并干燥。
2.如果材质为非活泼金属或未知材料，在配合面喷洒促进剂7649,并晾干30秒钟。
3.使用前充分摇匀。
3.为纺织胶水阻塞施胶嘴，应避免姣嘴接触金属物质。
5.对于通孔，在螺栓和螺母配合部位点胶。
4.对于盲孔，在盲孔地步滴胶，当装配时，内部空气会排出5.对于密封应用，将产品涂在外螺纹上(360°) 第-个螺纹不涂,将胶粘剂填满整个的螺纹间隙，对于更大的螺纹和间隙，可以调整涂胶量并且将产品应用在内螺纹上。
8.按正常操作装配螺栓，当需要.上紧到所需力矩时，力矩补偿并不需要。
二、拆卸环节1.用标准拆卸工具拆卸，2.在极少情况下，由于配合长度很长导致常温下无法拆卸，可以局部加热螺栓和螺母到232"C,趁热进行拆卸清洗3.对于固化的胶水，可将其浸泡在溶剂中或使用钢刷等工具进行机械打磨。

乐泰352典型固化特性：
乐泰胶水352在波长为365nm的紫外光照射下固化。要想使暴露于空气中的表面完全固化，也需250nm波长的紫外光照射。固化速度取决于照射到产品表面的紫外线光强。乐泰352也可以加热固化。粘接区域应当加热到121并在此温度下保持30分钟。
