外牆瓷磚壓貼工法與密貼工法抗拉接著強度之比較研究

Study on Comparing Tensile Adhesion Strength of Exterior Wall Tile with Pressure Application and Impacting Tool Placing Methods

Hazardous accidents caused by exterior wall tile peeling were reported periodically in Taiwan as well as from many other countries. Pull-off tests were applied in this research to reexamine the adhesive performances for different placing methods. Extruded and dust-pressed tiles were used for both methods as well. The average tensile adhesion strength with the electrical impacting tool of extruded and dust-pressed tiles were measured at 13.0kgf/cm2 and 13.3kgf/cm2. The average tensile adhesion strength of pressure application with additional 1kg metal ingot pressed down for extruded and dust-pressed tiles were measured at 11.1kgf/cm2 and 9.7kgf/cm2. Without the 1kg additional press down weight, the average tensile adhesion strength for extruded and dust-pressed tiles were measured at 9.1kgf/cm2 and 8.1kgf/cm2. Results show that placing method using electrical vibrator outperforms the other one. For pressure application placing method, extruded tile outperforms the dust-pressed tile. 建築物外牆瓷磚剝落，就像在台灣一樣，已經在世界各地造成許多的意外傷害事件。瓷磚拉拔試驗可應用於不同張貼工法黏著強度的試驗驗證；本研究主要是運用CNS 12611抗拉接著強度試驗法，比較有振動工具之密貼工法及沒有振動工具之壓貼工法（含壓1公斤重錘及不壓重錘），在使用不同背溝型式瓷磚張貼時，黏著強度的差異性。試驗結果顯示：密貼工法抗拉接著強度之平均值，使用有燕尾狀背溝射出磚張貼時，為13.0kg/cm2；使用沒有燕尾狀背溝粉壓磚張貼時，為13.3kg/cm2。壓重錘之壓貼工法，使用射出磚張貼時，為11.1kg/cm2；使用粉壓磚張貼時，為9.7kg/cm2。沒有壓重錘之壓貼工法，使用射出磚張貼時，為9.1kg/cm2；使用粉壓磚為8.1kg/cm2。研究結果顯示：使用密貼工法之抗拉接著強度明顯優於壓貼工法；使用射出磚張貼時之抗拉接著強度優於粉壓磚。
