结合实际生产情况,将酚醛尿烷树脂自硬砂中原砂的几种主要性能对最终造型结果的影响进行了归纳和总结,并通过正交实验验证,得出酚醛尿烷树脂各组分的最小质量分数和各组分之间的最佳配比关系。
Combined with the actual production situation, the influence of several main properties of the raw sand of phenolic urethane resin from the hard sand on the final molding result was summarized and concluded. Through the orthogonal experiment, the minimum of each component of the phenolic urethane resin was obtained Mass fraction and the best ratio between the components.
