汽车挡风窗玻璃、建筑门窗玻璃以及光学玻璃等一沾上水汽容易结雾,因此,须采用防雾玻璃。现将制造方法介绍如下: 把浓度为85％的H3PO4水溶液与K_2CO_3按30:1重量比混合,放入坩锅内加热至1000℃,反应10分钟后,冷却至500℃。把待处理的玻璃也加热至500℃,在上述混合溶液中浸5分钟,取出慢慢冷却 Automobile windshields, building windows and doors, optical glass and so easy to fog stained with water vapor, therefore, the use of anti-fog glass. Now the manufacturing method is described as follows: The concentration of 85% H3PO4 aqueous solution and K_2CO_3 by 30: 1 by weight ratio, placed in a crucible heated to 1000 ℃, the reaction 10 minutes, cooled to 500 ℃. The glass to be treated was also heated to 500 ° C, immersed in the mixed solution for 5 minutes, taken out slowly cooled
