如何保证真空玻璃的使用寿命

How to Secure the Life-cycle of the Vacuum Glass

真空玻璃的使用寿命包括力学寿命和真空寿命。需要从结构设计、材料选用、制作工艺等方面来保证真空玻璃的使用寿命。封接强度能够承受玻璃在自重、风载荷及温差作用下产生的应力,使封边不开裂,保持长期的力学寿命。通过使用低放气率的原材料、高温烘烤排气制作工艺及吸气剂的应用等方面,保证真空玻璃具有较长的真空寿命。经过理论计算真空玻璃放气量与吸气剂吸气量的关系,可以保证真空玻璃50年真空寿命。

The life-cycle of vacuum glass includes mechanical life and vacuum life, which could be guaranteed by many respects such as structure design, material selection, manufacture process etc. Bonding strength can bear deadweight, wind load and temperature stress so as to ensure that the edge could not crack and keep long physical life. By using low out-gassing materials, high-temperature baking exhausting process and application of getter, vacuum glass could have longer vacuum life. Making the best of the relationship between out-gassing of insulating glass and aspiratory capacity of getter through theoretical calculations, 50 years of vacuum life of insulating glass can be guaranteed.
