我们的导电弹性体密封件一直被选来用在航空、航海和地面电子设备上，以满足高等级的屏蔽和环境密封要求。在上百种应用中，我们在由我们加工或由我们客户提供的罩盖上模制导电弹性体，做成在屏蔽效果、安装和维护方面均具有明显优点的永久性密封/罩盖组件。结合我们的耐腐蚀、镀银铝填充硅酮和氟硅酮，这些组件特别适用于军用/航空航天应用中的环境要求
|
| |
|
| |
特 点 |
| |
|
| |
1)
由优良的材料着手---
我们的耐腐蚀CHO-SEAL
1285和1298银/铝衬料提供1
GHz时候的90
dB屏蔽效果、良好的耐盐雾性(MIL-STD810)
、EMP耐久性和-55至200℃的使用温度范围
2)
设计和成本上的优点
1．
衬料体积---
与模切衬料相比，通常密封材料要少，因而在许多应用场合，降低了成本
2．
断面设计---
压缩/变位要求能够符合采用不多的紧固件，结果是改善了可维护性
3．
紧固密封件---
允许紧固件能更方便地设计在衬料以内或者在衬料的外侧，减少EMI和水分通过紧固孔泄漏进入机箱
4．
生产节约---
衬垫、盖和压缩挡板成为一体，减少了外购项目和相应的后勤与文件
5．
安装节约---
不一致的和昂贵的粘合剂粘接操作被取消了
6．
现场可靠性和可维护性---
损坏的衬垫或罩子作为单件替换件，产生误用的可能性很小。导电衬垫也不会在日常维护中被普通的非导电衬垫来替换

我们能够就地模制上表所述的任何一种CHO-SEAL导电弹性体。选择满足你应用的性能标准的材料。
如果你希望我们提供给你完整的衬垫/罩组件，连同你要求的询价单，寄机箱外形的图纸到我公司。
如果你希望我们在现有的罩上模制CHO-SEAL弹性体，请寄图纸或实际的罩样品用于评估。
注意：提供用于模制的罩盖可能要求进行工装界面的改进，而且必须是未电镀和未涂漆的，但是能够由我们按照你的要求进行表面处理。
尺寸限制：我们能够生产任何总体尺寸大于19x19mm的就地模制的衬垫/底板组件。对于平的衬料，推荐的最小衬料外形断面是1.6mm长，最小厚度是0.5mm。断面和厚度再小的产品尽管不推荐也能供应。

All Spira-Cell,
Econo-Cell, and Fan Filters include our
patented “blending” process of the aluminum
honeycomb panel that provides high and
reliable levels of shielding. Our filters
also include the use of epoxy which
mechanically bonds the honeycomb panel to
the frame and the use of our patented spiral
EMI gasket, which ensures an excellent,
long-lasting EM bond between the panel and
the frame.
|
| |
|
| |
特 点 |
| |
|
| |
The shielding effectiveness graphs
illustrate the shielding of
1/8”
cell by
1/4”
thick honeycomb panels including: (A) the
level of shielding obtained from a typical
honeycomb panel; (B) the shielding from a
panel which has been processed using our
patented blending process; and (C,D) the
shielding obtained from tin plated honeycomb
panels, where most of the incidental contact
points across the epoxy joint were removed
from one of the panels during the
pre-plating cleaning process (D).
