塑料件修复

[中文适用范围]： 目的和范围：本 SAE 推荐做法旨在提供有关由非金属材料制成的轻质柔性保险杠组件的维修和整修的信息。这些部件中塑料化合物的使用已从现在熟悉的聚氨酯扩展到包括聚碳酸酯共混物和改性聚丙烯。其中一些材料@即聚烯烃类的混合物@需要专门的产品@例如粘合促进剂@以使修复材料能够粘附到基材上。此类组件的使用范围正在扩大，特别是在乘用车保险杠上。经验表明，即使在遭受相对严重的碰撞损坏后，这些相对昂贵的部件也可以轻松修复。可以使用车身修理厂供应商提供的多种结构修复产品进行修复。此推荐做法说明了如何修复典型保险杠盖上的损坏1。应该注意的是，使用电动工具@时应采取适当的安全预防措施，并且应始终遵循与每个制造商的产品相关的说明。 1报告中描述的程序基于 Tech-Cor 研究和工程人员所做的工作和研究。 [外文原描述]： This SAE Recommended Practice defines the information required to repair the various types of plastics found on modern light-duty highway vehicles. Information is included for the repair and refinishing of most plastic body parts, both interior and exterior. Repair information is described for all commonly used plastics including, but not limited to, polyurethanes, polycarbonate blends, modified polypropylenes, polyethylenes and nylons. Repairs can be made to these types of plastics using two-part (2K) repair adhesives, plastic welding, and other materials available from body shop suppliers. When a new type of plastic is being introduced to the market through a new vehicle program, specific repair and refinishing procedures should be provided, following the format in this document.Sheet-molded compounds (SMC), fiber-reinforced plastics (FRP) and carbon fiber reinforced plastics can also be repaired using slightly different procedures and repair materials.Cross Reference: J1344_201703,J2376_201910
