节能性与结构耐久性俱佳的新型暖边系统—Kodispace 4SG

New Type of Warm Edge System with Good Energy Saving and Structure Durability-Kodispace 4SG

本文介绍了一项创新性反应型丁基隔条技术。这项技术使采用结构装配的建筑外立面中的中空玻璃单元具备国际先进的暖边性能与优越的气密性。在极端的环境条件下,中空玻璃单元中的二道密封胶能够承受由于风荷载和极端温度而产生的高应力。为了适应上述应力,科技人员设计了一套反应型丁基系统,该系统融合了隔条、干燥剂与丁基密封胶的各项功能。相比于刚性隔条,这套隔条系统利用中空玻璃单元的整个内部空间来吸收由于环境应力引起的形变。该隔条与玻璃和第二道硅酮密封胶的化学粘合保证了封边条卓越的耐久性。由于在产品应用中采用电脑控制,再加上隔条的极低的渗透性,在正常大规模生产条件下,中空玻璃单元也能达到EN 1279-3(气密性)标准的要求。这就使三玻两腔的中空玻璃的制作变得尤为简单,更易于制作高精度的大板结构中空玻璃,造型设计也更加自由。创新的反应型隔条系统已成为中空玻璃单元技术领域的里程碑,为建筑外立面带来了卓越的耐久性和节能效果,使建筑外立面的能源可持续性迈出了辉煌的一步。

This paper introduces an innovative reactive technique of Butyl edge spacer. This technology enables the insulating glass units in the structural facade of the building with internationally advanced warm edge performance and superior air tightness.Under extreme environmental conditions, the secondary sealant in the insulating glass unit could withstand high stresses due to wind loads and extreme temperatures. In order to afford the above high stresses, the technical and scientific professionals designed a reactive Butyl edge spacer, which combines the functions of spacer, desiccant and butyl edge sealant. Compared with the rigid edge spacer, this spacer system uses the whole interior space of the insulating glass unit to absorb the deformation caused by environmental stress.The chemical bonding of the edge spacer with glass and the secondary silicone sealant together ensures the excellent durability of the sealing strip. Because of the use of computer control in product applications and the extremely low permeability of the edge spacer, the insulating glass unit can also meet the EN 1279-3 （air tightness） standard under normal large-scale production conditions. It enable the production of three-glass two-cavity insulation glass especially simple,and makes it easier to make high-precision insulating glass of large plate structure, and it is freer to design the modeling.The innovative reactive edge spacer system has become a milestone in the field of insulation glass unit technology, bringing remarkable durability and energy-saving effects to the building facade, and taking a positive step towards the energy sustainability of the building facade.
