电子元件 盆栽

电子元件本身需要防潮和防机械损坏。因此,电子元件通常使用具有保护特性的材料进行密封。电容器、开关和继电器等元件通常设计有较浅的封装腔,以便在自动化生产过程中快速分配低粘度灌封材料。

Hoenle 提供 Vitralit® 品牌的单组分光固化灌封材料或 Structalit® 系列的热固化灌封化合物。这两个品牌的粘合剂都是专门为防止污染、化学品、湿气和操作损坏而配制的。这些材料易于分配,固化速度快,可提供干燥、无粘性的保护表面。Hoenle 的灌封材料选择广泛,可粘接各种基材,包括 ABS、尼龙、聚碳酸酯和电镀金属。

Vitralit® 系列粘合剂是光固化灌封材料。它们是单组分、无溶剂的,易于从自动阀门分配系统中分配。有多种粘度可供选择,以满足组件配置和加工挑战。固化后,这些材料的表面干燥、无粘性,可防止空气中的微粒和操作过程中的污染。光固化材料还可提供二次湿固化或热固化催化剂,以应对灌封领域中存在的阴影区域。

LED 固化粘合剂是 Hoenle 用于电子元件灌封和封装的产品之一。在低强度紫外线或可见光下,这些粘合剂可在几分之一秒内完全固化。它们非常适合与 LED 光固化装置配合使用;根据照射面的不同,Hoenle 的泛光灯尤其适用。

Structalit® 粘合剂是不含溶剂的单组分或双组分粘合剂。它们主要以环氧树脂为基础,可在室温下固化或加热固化。对于热敏性部件,可使用低温固化粘合剂。
