1 聚氨酯蜂窝弹性体1.1.制造与加工聚氨酯蜂窝弹性体(PUR),或称发泡聚氨酯弹性体,如 Cellasto,其密度在200~650公斤/米~3之间。它是通过多羟基组分(聚酯或聚醚)和二异氰酸酯发生反应,随后利用蜂窝发泡剂发泡制成的。本文仅讨论由聚酯多元醇和1.5-萘二异氰酸酯制成的聚氨酯弹性体。蜂窝材料成形件的加工应根据零件的数量或重量以及加工属于连续性或非连续性而定。
1 Polyurethane Cellular Elastomer 1.1. Manufacture and Processing of Polyurethane Cellular Elastomer (PUR), also known as Foamed Polyurethane Elastomer, such as Cellasto, with a density between 200 and 650 kg / m3. It is made by reacting polyol components (polyesters or polyethers) with diisocyanates and subsequently foaming with a cellular foaming agent. This article discusses only polyurethane elastomers made from polyester polyols and 1.5-naphthalene diisocyanates. The processing of honeycomb formed parts should be based on the number or weight of the parts and on the continuity or discontinuity of the process.
