水玻璃砂的常温强度越高，其溃散性通常越差。
In general, the higher the atmospheric temperature strength of the sodium silicate sand is, the more deteriorative its collapsibility becomes.
试验结果表明，超声处理虽然提高了水玻璃砂的常温强度，却也恶化了溃散性；
The experimental results indicate that ultrasonic processing can improve the normal temperature strength of sodium silicate sand, but deteriorate its collapsibility.
