      如何消除鋼化玻璃中硫化鎳引起的玻璃自爆?
      發(fā)布時(shí)間:2023-02-22 閱讀量:2043

      1. 為了消除硫化鎳對(duì)鋼化玻璃引起的不利影響,在鋼化爐對(duì)玻璃完成鋼化后,應(yīng)采用均質(zhì)爐對(duì)鋼化玻璃進(jìn)行均質(zhì)處理;

      2. 均質(zhì)爐是將鋼化玻璃加熱到硫化鎳的相變溫度,以促使硫化鎳迅速相變,硫化鎳的體積會(huì)膨脹2%~4%;

      3. 如果硫化鎳的位置是在鋼化玻璃張應(yīng)力區(qū)內(nèi),則其體積膨脹就會(huì)引爆存在自爆隱患的鋼化玻璃;在剔除了自爆玻璃后,就相應(yīng)的提高了鋼化玻璃的成品率;
