为什么选择 CIM4196/6196 Why CIM4196/6196

深冷保冷，难的不只是降低冷量损失

Cryogenic Insulation: The Hard Part Isn't Just Reducing Heat Gain

LNG及深冷系统长期处于较大的内外温差和水蒸气分压力差环境中。除降低环境热量向低温介质传递外，控制水汽向低温侧迁移、保持阻汽结构连续性以及维持保冷系统完整性，同样关系到系统长期运行可靠性。

CIM4196/6196面向最低-196℃深冷工况开发，将低温绝热性能、低透湿阻汽结构与柔性材料特性结合，满足LNG及复杂深冷设备、管道的保冷需求。

LNG and cryogenic systems operate under large temperature differentials and vapor-pressure gradients. Beyond reducing heat transfer from the environment, controlling moisture migration toward the cold side, maintaining vapor-barrier continuity, and preserving system integrity are equally critical to long-term reliability.

CIM4196/6196 is designed for deep-cold conditions down to -196℃, combining low-temperature thermal performance, low-permeability vapor-barrier structure, and flexible material characteristics to meet the cold insulation needs of LNG and complex cryogenic equipment and piping.

更低导热系数，为薄型化设计提供条件

Lower Conductivity Enables Thinner Design

较低的低温导热系数可在满足项目保冷要求的前提下，为降低保冷系统设计厚度提供条件。具体保冷厚度应根据介质温度、管径、环境温湿度、允许冷损及表面温度要求等工况参数计算确定。

Lower low-temperature conductivity can reduce insulation system design thickness while meeting project cold-insulation requirements. Actual thickness must be calculated based on medium temperature, pipe diameter, ambient temperature/humidity, allowable cold loss, and surface temperature requirements.

水汽控制 Moisture Control

深冷系统的长期性能，也取决于如何管理水汽

Long-Term Performance Also Depends on Moisture Management

外部环境 外护系统 阻汽层 CIM保冷层 深冷管道 水汽 阻汽结构控制水汽向低温侧迁移 环境温度 -196℃

深冷系统运行过程中，环境水汽具有向低温侧迁移的趋势。一旦阻汽系统的连续性受到破坏，水汽进入保冷结构后可能发生冷凝甚至结冰，并进一步影响保冷系统的绝热性能和长期稳定性。

因此，深冷保冷不能只关注材料导热系数，还需要将保冷材料、阻汽层、接缝密封及外护系统作为完整结构进行设计和施工。

During operation, ambient moisture migrates toward the cold side. If vapor-barrier continuity is compromised, moisture entering the insulation may condense or freeze, further degrading thermal performance and long-term stability.

Therefore, cryogenic insulation cannot focus solely on material conductivity — the insulation, vapor barrier, joint sealing, and jacketing must be designed and constructed as an integrated system.
