摘要
比较了磷酸盐、水玻璃、呋喃树脂三种自硬砂的工艺性能，其结果为：磷酸盐自硬砂虽有良好的热稳定性和溃散性，但强度和吸湿性等较树脂自硬砂差，价格比水玻璃砂高得多，应用前景并不乐观．
The technical functions were compared for phosphate-bonded sand.silicate-bonded and furan nobake sand. The experimental results shows that phosphate-bonded sand has high quality for thermal stability and collapsibility. But its some function are worse than furan. for example,the strength and hygroscopicity. Its price is far costlier than silicate-bonded, therefore. the future is no more optimistic.
