开孔泡沫塑料
open-cell foamed plastics
- 通过碳酸氢铵发泡法发泡制得开孔改性脲醛树脂泡沫塑料。
Gain Modified urea formaldehyde resin foam plastics by the carbonic acid hydrogen ammonia. - 采用全水发泡工艺，通过对配方的调节，研制了一种具有较高耐压强度和较好降噪性能的聚氨酯开孔硬质泡沫塑料。
The water-blown rigid polyurethane foam which had higher compressive resistance and better noise reduction effect were prepared by formulation adjustment. - 采用全水发泡工艺，通过对配方的调节，研制了一种具有较高耐压强度和较好降噪性能的聚氨酯开孔硬质泡沫塑料。
The result showed that noise reduction effect of the foam was the best when aniline polyether polyol A and low viscosity polyether polyol B were used, with the open-cell agent content was 3.
