  1994年,日本板硝子株式會社(NSG)購買了悉尼大學的專利使用權,并于1997年正式生產出真空玻璃產品。1998年,中國真空玻璃開始發展,但直到2008年,中國制定了世界上第一個真空玻璃行業標準JC-T1079-2008后,真空玻璃的“廬山真面目”才快速地被國人所知曉。

  二、真空玻璃的主要性能

  【真空玻璃的保溫不性能】

 
  真空玻璃中間的真空層將氣體的傳導和對流傳遞的熱量降至很低,以至于可以忽略不計。因此,真空玻璃比具有更好的保溫隔熱性能。真空玻璃優異的性能具體表征的技術參數是—,其表示熱量通過玻璃中心部位而不考慮邊緣效應,穩態條件下,玻璃兩面單位空氣溫度差時,單位時間通過單位面積的熱量,U值的單位是:W/(㎡•K)。而真空玻璃的真空層內無空氣,更無水汽分子,極嚴,大,到了冬天不會產生結露現象。
