弯弧硼硅防火玻璃参数及耐火性能研究
Study on Parameter and Fire Resistance of Curved-Arc Borosilicate Glass

硼硅玻璃具有许多优异特性，如软化点大于820℃、膨胀系数低(是普通玻璃的1/3~1/2)、重量轻、硬度高、高透光率、无自爆等杰出的安全防火优异性能，已被广泛应用于现代建筑中。本文对弯弧硼硅防火玻璃的耐火性能进行了探索，依据硼硅玻璃特性，改进设备工艺，摸索出弯弧硼硅玻璃的加工要点及参数，最终将建筑中常用的6 mm、8 mm弯弧硼硅玻璃经加工后可通过2小时耐火完整性检测，同时满足国家安全玻璃的标准。
Borosilicate glass has many excellent characteristics, such as softening point greater than 820？C, low expansion coefficient (1/3 - 1/2 of clear glass), light weight, high hardness, high light transmittance, no self explosion and other excellent safety and fire protection properties. It has been widely used in modern buildings. In this paper, the fire resistance of curved-arc borosilicate fireproof glass is explored. According to the borosilicate glass properties, the equipment technology was improved, and the processing points and parameters of curved borosilicate glass were explored. Finally, 6 mm and 8 mm curved borosilicate fireproof glass passed the 120 min fire resistance integrity test, and met the national safety glass standard at the same time.
