近年来玻璃纤维工业生产中的下脚料-玻璃纤维丝头,被用来制作玻璃丝菱苦土瓦投放市场。这种瓦一般多用于民用建筑,在应用过程中仍出现裂纹、风化、腐蚀现象。为了提高玻璃丝瓦的强度和抗冲击性能,我们研制和试验了高强度玻璃丝布瓦,经过静载负荷试验,其800毫米支距破断强度达到620公斤,抗冲击跌落高度达到5米,其强度是建标23-61规定标准的4.8倍,屋面施工可承受背人行走的动荷载,施工、搬运、提升作业中完好率达到100％无损坏。 1.高强玻璃丝布小波瓦的制作玻璃丝布瓦的主要材料为菱苦土,胶结料为氯化镁溶液,调成糊状后平摊于瓦楞胎模上,先铺一层玻璃丝,加铺
In recent years, in the production of glass fiber industry, the waste-glass fiber yarn head was used to make the glass silk tile. This type of tile is generally used in civil buildings and cracks, weathering, and corrosion still occur during application. In order to improve the strength and impact resistance of the glass fiber tile, we have developed and tested a high-strength glass fiber tile. After a static load test, the breaking strength of the 800 mm offset reaches 620 kg, and the impact drop height reaches 5 meters. Its strength is It is 4.8 times the standard required by the construction standard of 23-61, and the roof construction can withstand the dynamic load of walking. The intact rate of construction, handling, and lifting operations reaches 100% without damage. 1. The production of high-strength glass wool cloth wavelet The main material of glass silk cloth is magnesite, and the cement material is magnesium chloride solution. After being transferred into a paste, it is evenly distributed on the tile tire mold. The first layer is covered with glass fiber.
