Stress relaxation / recovery capacity
受壓/恢復(fù)能力 |
|
|
|
| Silicones 硅硐膠： |
|
* 高恢復(fù)性能，適用于快速/時(shí)間短的移動(dòng)物體，比如裝窗玻璃
High recovery capacity ideal for fast / short movements e.g. window glazing
* 因?yàn)榕c基面接觸的經(jīng)常性應(yīng)力因素，在移動(dòng)縫中是至關(guān)重要的
Critical in movement joints (facade) because of constant stress / stress build up on contact to substrate
* 粘結(jié)性 adhesion! |
|
|
| Polyurethane 聚氨酯膠： |
|
* 正確配方的聚氨酯膠在經(jīng)常性的應(yīng)力下顯示出舒緩壓力的性能（比如：Sikaflex 15LM)
Properly formulated polyurethane show stress relaxation under constant stress (e.g. Sikaflex 15LM)
* 低風(fēng)險(xiǎn) lower risk
* 基面很少或幾乎沒有受到張力 no / less stress build up on contact to substrate |
|
|
|
Tear propagation resistance
抗拉伸性 |
|
|
| Silicones 硅硐膠： |
|
* 耐撕裂性差，即使很小的接縫損壞也有大的風(fēng)險(xiǎn)
Low tear resistance risk of major failure even if just small damage of joint
* 質(zhì)量控制難度大 Quality of application more critical
* 高恢復(fù)性能 High recovery capacity
* 無(wú)張力舒緩性 no stress relaxation |
|
|
| Polyurethane 聚氨酯膠： |
|
* 即使成本很低的產(chǎn)品，其抗撕裂性及耐磨性非常好
Excellent tear resistance even low cost products
* 對(duì)施用者來(lái)說(shuō)安全指數(shù)高 More safety margin for applicator |
|
|
|
Not suitable for horizontal joints (floor applications)
是否適用于水平接縫（地板的使用上） |
|
|
| Silicones 硅硐膠： |
|
* 機(jī)械破壞的危險(xiǎn) Risk of mechanical damage
* 耐磨抗撕裂性能差 low tear resistance
* 受污染的風(fēng)險(xiǎn) Risk of staining
* 機(jī)械性能不足以用作地板接縫施工 Mechanical properties insufficient for floor joints |
|
|
| Polyurethane 聚氨酯膠： |
|
* 因?yàn)槠鋬?yōu)良的性能，是作為地板粘結(jié)的最好材料,比如Sikaflex 11FC
Best solution for floor joints because of excellent properties,e.g. Sikaflex 11FC |
