  ④高效无味胺类催化剂的使用,有效调整发泡-凝胶反应的平衡,使喷涂层间表皮较薄,利于冷库保温材料性能的体现;

  ①特种高官能度聚醚复配使用,使泡沫形成立体网状结构,大大提高了泡沫耐低温性能;而目前喷涂料常使用的4110聚醚中含有大量二官能度成分,反应后形成的大量的线性分子结构在低温情况下很难稳定;

四、 关于聚氨酯冷库保温材料发方数的建议:

冷库投资是一项长期的、有收益回报的投资,发方数高诚然能够减小初期投资,但需要把握一定的限度,要把长期的能耗与初期投资综合考虑,因为聚氨酯冷库保温材料的保温效果与其容重有着抛物线性的关联性;大量研究表明泡沫容重在33~35公斤/立方米时具有较好的保温性能,因此通常建议恒温冷库发方数在22~23/吨比较合适。
