通过对动物蛋白质胶型（芯）砂的两种固化工艺的试验比较，表明用微波加热固化动物蛋白质胶型（芯）砂的硬透性好、固化速度快、节能，且不易过烧，砂型（芯）强度稳定。差热分析和红外光谱分析表明，动物蛋白质胶为含有系列氨基酸的多肽物质，其固化机理包括化学反应和物理脱水，特别适合于利用微波加热固化。 By comparing the two curing processes of animal protein gel (core) sand, it shows that the hard protein permeability (core) sand solidified by microwave heating has good hard permeability, fast curing speed, energy saving, and is not easy to overheat. The sand type (Core) strength and stability. Differential thermal analysis and infrared spectroscopy analysis showed that the animal protein glue is a polypeptide material containing a series of amino acids. The curing mechanism includes chemical reaction and physical dehydration, and is particularly suitable for curing by microwave heating.
