1、Troubleshooting问题解决,Training 2008.9,2,Bond Failure Modes of ASTM D429ASTM D429定义的粘结失效模式,Primer底涂胶粘剂,Adhesive面涂胶粘剂,Rubber橡胶,Metal/Substrate金属/基材,R = Rubber retentionR=橡胶,RC = Rubber-to-CementRC=橡胶与面胶,CP = Cement-to-PrimerCP=面胶与底胶,CM = Cement-to-MetalCM=底胶与金属,COH = CohesiveCOH=内聚破坏,3,Cement-to-Metal F
2、ailureCM失效模式,Designated as CM or M CM或M的定义Primer or adhesive failure at the substrate interface 底涂或单涂胶粘剂与基材界面的粘结失效25+of failures in industry 在工业中占25失效比例Common Causes of Failure: Improper substrate preparation, improper handling/application of Primer or Adhesive 典型的失效因素：不合适的基材处理，不正确的胶粘剂应用,Primer,Adhe
3、sive,Elastomer,Metal/Substrate,Adhesive,Elastomer,Metal/Substrate,CM,CM,Two Coat System,One Coat System,4,CM FAILURE CM失效模式,5,Cement-to-Primer FailureCP失效模式,Designated as CP CP的定义Cement = Adhesive Cement =面涂胶粘剂Failure occurs between primer and adhesive 失效发生与底涂与面涂胶粘剂间10% of failures in industry 工业上发生
4、概率10%Common Causes of Failure: Contaminated primer surface or improper handling/application of Primer or Adhesive, plasticizer migration from compound 典型的失效因素：底涂表面被污染或不正确的胶粘剂应用，增塑剂的迁移,Primer,Adhesive,Elastomer,Metal/Substrate,CP,6,CP FAILURE CP失效模式,7,Rubber-to-Cement FailureRC失效模式,Designated as RC,
5、cement = adhesive RC失效定义，cement = 面涂胶粘剂Failure occurs between rubber and adhesive 失效发生在橡胶与胶粘剂间Look for evidence of adhesive adhering to substrate, but not to rubber surface 胶粘剂与基材有良好的粘结，但是与橡胶表面粘结失效50+% of failures in industry 工业上发生概率50+%Common Causes of Failure: Adhesive applied too thin, improper m
6、old cycle, bond-line stresses during de-mold, improper adhesive choice 典型的失效因素：胶粘剂太薄，不正确的硫化和脱模，胶粘剂选择错误,Primer,Adhesive,Rubber,Metal/Substrate,RC,Rubber,Adhesive,RC,Metal/Substrate,Two Coat System,One Coat System,8,RC failure RC失效模式,9,Cohesive Failure胶粘剂内聚破坏,Not a ASTM type but failure occurs within
7、either primer or adhesive layer 不是ASTM失效模式，但会在底涂或面涂胶粘剂层间发生Failure occurs within either primer or adhesive layer 失效发生在胶粘剂的层间5% of failures in industry 工业上发生概率5%Common Causes for Failure: Improper handling/application such as Primer or Adhesive is too thick 典型的失效因素：不正确的胶粘剂应用或胶粘剂太厚,Primer,Adhesive,Elas
8、tomer,Metal/Substrate,COH,10,Mixed Failure Modes: 20%R, 30% RC, 50%CM混和失效模式： 20%R, 30% RC, 50%CM,11,Methods for Troubleshooting Bond Failures,Provide/define the circumstances of the bond failure 定义粘结失效情况Inspect/determine failure mode(s), location, amount 检测失效模式，位置，数量Review production materials and r
9、elated processing 审核产品材料和相关工艺Create a list of potential causes 提出一系列潜在的因素 Develop a corrective plan and test 提出改进的计划及测试Change material and/or process to verify cause(s) 根据影响因素更改材料或改进工艺Perform only one change at a time 每次只改变一个影响条件,12,Failed Part Checklist 客户失效零件检查表,Date日期:_ P/N & Description of Part:
