采用水热热压法回收废玻璃，生产高密度压坯。研究了不同反应变量(温度、时间、含水率和加载压力)对几种废玻璃压实过程的影响。所有玻璃的致密化开始于120°C左右，并随着温度的升高而迅速进行。在水热热压条件下，废玻璃的压实受温度和水含量的影响最大，受反应时间和加载压力的影响较小。在200℃、10wt%含水率下，施加60 Mpa的加载压力2小时后，‘蓝色’玻璃的最大拉伸强度为65 Mpa。
Abstract Recycling of waste glasses has been conducted by a hydrothermal hot-pressing method to produce high density compacts. Our research was focussed on the intluence of various reaction variables (temperature, time, water content and loading pressure) during compaction of several types of waste glasses. The compaction of all glasses starts around 120°C and proceeds rapidly with increasing temperature. Under hydrothermal hot pressing conditions, the compaction of the waste glass is most strongly controlled by temperature and water content, and affected to a lesser degree by reaction time and loading pressure. A maximum tensile strength of 65 MPa was obtained for ‘blue’ glass at 200°C, 10wt% water content, after applying 60 MPa loading pressure for 2 hours.
