夾縫密封之豬腸選購小知識
我們為夾縫進行密封，除了選用西卡密封膠之外，點樣可以事半功倍呢❓
答案💡👉🏻在唧膠前在施工位置上加放墊底膠條(俗稱豬腸)就可以👌🏻
豬腸🐷的功用
1) 豬腸有效阻隔空氣上升⬆️，在密封膠固化前能有效防止❌氣泡形成。
2) 在夾縫底部加入豬腸, 可防止密封膠黏實邊夾縫底部。當伸縮縫遇上熱漲冷縮🌡️時，豬腸可以充當緩衝的作用，密封膠便不會🙅‍♂️因為拉扯而容易損毀。
3)使用豬腸可以為夾縫作深度定位，使密封膠的施工過程更加順暢🤗。
💡豬腸選購小貼士
✔️呎寸
我們建議豬腸的大小要比夾縫大約20%，這樣才可有效地讓豬腸可以穩固地固定在夾縫😀。
✔️物料
豬腸必須是不透氣的PE物料，這樣才有效阻隔熱空氣上升⬆️，避免密封膠未固化前形成氣泡。

Joint Sealing - Backer Rod Selection Tips
How can we achieve the best result for joint sealing❓
The answer is simple💡👉🏻by adding backer rode on the substrate before application👌🏻
The function of Backer Rod🐷
1) The backer rod can effectively block the air from rising⬆️ that could prevent the formation of air bubbles❌ before the sealant is cured.
2) By using backer rod, the sealant could avoid damage caused by pressure generated from expansion and contraction. 🌡️ 🙅‍♂️
3) Backer rod helps to locate the joint depth which could ease the sealing application. 🤗
💡Backer Rod Selection Tips
✔️Size
We recommend the size of the rod should be approx. 20% larger than the joint size, this helps to ensure the rod can be firmly fixed within the joint.
✔️Material
Closed cell PE material is an ideal choice for backer rod as the material could block the hot air from rising effectively.
