摘要
]本研究将经过硝化氧解的年轻褐煤粉与聚乙烯酸水溶液在酸性条件下和醛类发生缩醛化反应，制取煤粉成型用型煤粘结剂。本文介绍了型煤粘结剂制备及压制工艺的研究，并对合成反应机理进行了探讨。
The adhesive used in pelletizing fine coal can be prepared by the acetalation of nitrified and oxidated fine young brown coal with PVA solution and aldehyde in acid condition. Research on the process of preparation and press for the adhesive was introduced, and systhetic mechanism was discussed in this paper.
