摘要
PEPSET酚基尿烷自硬砂具有反应滞后、快速硬化的特点,可使用时间与起模时间的比值高,型砂流动性好.本文论述了PEPSET自硬砂的工艺特点以及PEPSET自硬砂的应用现状和应用前景.
PEP SET phenolic urethane nobake sand possesses the features of delayed reaction and setting fast, so the ratio of working time and stripping time is very high and the flowability of molding sand is good. This paper has described the technology feature of PEP SET process. The present application and development are discussed too.
