sodium silicate-bonded sand%butyl acetate%retained strength
本文选择乙酸丁酯对水玻璃砂进行硬化。研究结果表明,水玻璃加入量为4.0wt%时,乙酸丁酯加入量控制在9.0wt%为宜,此时水玻璃砂的残留强度较低,可解决铸钢件生产过程中存在的残留强度高、铸件落砂困难的问题。
本文選擇乙痠丁酯對水玻璃砂進行硬化。研究結果錶明,水玻璃加入量為4.0wt%時,乙痠丁酯加入量控製在9.0wt%為宜,此時水玻璃砂的殘留彊度較低,可解決鑄鋼件生產過程中存在的殘留彊度高、鑄件落砂睏難的問題。

This paper chooses the butyl acetate for the induration of sodium silicate-bonded sand. The result shows that: when the addition of sodium silicate-bonded is 4.0wt%, the best addition of butyl acetate is 9.0wt%. in this addition, the retained strength of sodium silicate-bonded sand is low. It can solve the problems of the high retained strength and the difficulties of casting shakeout in the steel production process.
