In the first part of this publication, selected technological and strength properties of synthetic molding sand bound with sodium bentonite with the addition of a new lustrous carbon carrier (R, R, R, W, P, Z, P, P, S, ρ) were determined. The introduction of polyethylene as a substitute for hydrocarbon resin, and shungite as a replacement for coal dust, demonstrated the achievement of an optimal molding sand composition for practical use in casting technology. The sand containing a new lustrous carbon carrier (SH/PE) demonstrates the highest permeability and flowability. Based on the analysis of the obtained results, it should be concluded that to achieve the desired level of the measured properties in the sand with the mixture of precursors SH/PE, the moisture content should be in the range of 1.5% to 1.7%.
在本出版物的第一部分，测定了添加新型光亮碳载体（R、R、R、W、P、Z、P、P、S、ρ）的钠膨润土粘结合成型砂的选定工艺性能和强度性能。引入聚乙烯替代烃类树脂，引入水镁石替代煤粉，证明获得了用于铸造技术实际应用的最佳型砂成分。含有新型光亮碳载体（SH/PE）的型砂具有最高的透气性和流动性。基于对所得结果的分析，应该得出结论，为了在用前驱体SH/PE混合物制成的型砂中达到所需的测量性能水平，含水量应在1.5%至1.7%的范围内。
