摘要
用废腈纶经催化水解制得了一种新型铸造黏合剂,探讨了影响样砂抗拉强度的各种因素,结果表明,该黏合剂具有砂强度高、溃散性好,发气量少,无污染等优良特点。
The waste polyacrylonitrile hydrolyzed catalytically was processed into a new type of foundry binder. The main factors affecting bonding strength were studied. The result of the binder was high strength, good collapsibility and few pollution.
