摘要
采用自行生产的 PTMG型聚氨酯预聚体为原料 ,通过对物料配比、浇注工艺、添加剂等条件的研究 ,制得物理机械性能优良、机械加工性能好的聚氨酯密封胶筒 ,可替代进口产品。
The polyurethane airproof canisters which had good physical mechanical properties and machining behavior by the study on material proportion, casting technology and additive were developed based on PTMG type polyurethane preplymer made by ourselves, and it could replace the imports.
