Stress relaxation / recovery capacity
受压/恢复能力 |
|
|
|
| Silicones 硅硐胶： |
|
* 高恢复性能，适用于快速/时间短的移动物体，比如装窗玻璃
High recovery capacity ideal for fast / short movements e.g. window glazing
* 因为与基面接触的经常性应力因素，在移动缝中是至关重要的
Critical in movement joints (facade) because of constant stress / stress build up on contact to substrate
* 粘结性 adhesion! |
|
|
| Polyurethane 聚氨酯胶： |
|
* 正确配方的聚氨酯胶在经常性的应力下显示出舒缓压力的性能（比如：Sikaflex 15LM)
Properly formulated polyurethane show stress relaxation under constant stress (e.g. Sikaflex 15LM)
* 低风险 lower risk
* 基面很少或几乎没有受到张力 no / less stress build up on contact to substrate |
|
|
|
Tear propagation resistance
抗拉伸性 |
|
|
| Silicones 硅硐胶： |
|
* 耐撕裂性差，即使很小的接缝损坏也有大的风险
Low tear resistance risk of major failure even if just small damage of joint
* 质量控制难度大 Quality of application more critical
* 高恢复性能 High recovery capacity
* 无张力舒缓性 no stress relaxation |
|
|
| Polyurethane 聚氨酯胶： |
|
* 即使成本很低的产品，其抗撕裂性及耐磨性非常好
Excellent tear resistance even low cost products
* 对施用者来说安全指数高 More safety margin for applicator |
|
|
|
Not suitable for horizontal joints (floor applications)
是否适用于水平接缝（地板的使用上） |
|
|
| Silicones 硅硐胶： |
|
* 机械破坏的危险 Risk of mechanical damage
* 耐磨抗撕裂性能差 low tear resistance
* 受污染的风险 Risk of staining
* 机械性能不足以用作地板接缝施工 Mechanical properties insufficient for floor joints |
|
|
| Polyurethane 聚氨酯胶： |
|
* 因为其优良的性能，是作为地板粘结的最好材料,比如Sikaflex 11FC
Best solution for floor joints because of excellent properties,e.g. Sikaflex 11FC |
