In this paper, a new craft of organic ester-sodium silicate self-hardening sand was used owing to shortage of traditional technology in which red mire organic ester-sodium silicate self-hardening sand was used originally.
针对赤泥水玻璃自硬砂传统工艺的不足,改用有机酯水玻璃自硬砂新工艺,通过工艺试验,确定了有机酯水玻璃自硬砂的生产工艺,经过试生产之后,已经在球铁和铸铁件上应用,取得了成功,获得了满意的效果。
The collapsibility of self-hardening sand is improved by modified silicate sodium.
采用改性水玻璃改善自硬砂溃散性的试验研究表明,改性水玻璃—酯自硬砂溃散性良好,再配以QM附加物,自硬砂残留抗压强度进一步降低,在800℃时残留强度小于0。
