摘要： Insulation panels are for use in providing a gas insulation layer between a surface and a liquid having a low boiling temperature. The insulation comprises a cellular or honeycomb core having a plurality of discrete cells enclosed by a capillary cover with capillary openings communicating with each cell. The honeycomb core is tensioned and also is shaped to an arcuate or concave configuration before the capillary cover is adhesively secured thereto. The adhesive forms a smoothly radiused joint between the core walls and the capillary cover with the adhesive being feathered on the cover and the walls immediately adjacent the joint. Vacuum is applied to each cell to form a dimple in the capillary cover and the capillary openings are then formed in the cover. A filler material may be placed in each cell and a backing sheet applied to the core to maintain the filler in the cells and facilitate assembly of the panel to the surface to be insulated. Each cell may be tested individually by applying a vacuum to the capillary opening associated with that cell and, if a leak between the capillary cover and the core is detected, the portion of the cover over that cell may be removed and a predimpled cover patch secured over the cell.
摘要翻译： 绝缘板用于在表面和具有低沸点温度的液体之间提供气体绝缘层。 绝缘体包括具有由毛细管盖封闭的多个分立单元的蜂窝状或蜂窝状芯体，毛细管开口与每个单元连通。 蜂窝芯被张紧，并且在将毛细管盖粘附固定到其上之前也被成形为弓形或凹形。 粘合剂在芯壁和毛细管盖之间形成平滑的圆弧形接头，其中粘合剂被羽化在盖子上并且紧邻接头的壁上。 真空被施加到每个细胞以在毛细管盖中形成凹坑，然后在盖子中形成毛细管开口。 填充材料可以放置在每个电池中，并且将背衬片施加到芯部以将填料保持在电池中，并且便于将面板组装到待绝缘的表面。 可以通过对与该电池相关联的毛细管开口施加真空来单独测试每个电池，并且如果检测到毛细管盖和芯之间的泄漏，则可以去除该电池上的盖的部分，并且将预镀覆盖片固定 在细胞上
