Donpipe 322 hcfc-141b base base pold polyols yePipeiline Shell
INtbroction
Donpipe 322 rudzi rwepamhepo blend neHCFC-141B sekusimudzira mumiririri, kutora polyol seyakanyanya zvinyorwa zvekushandisa, kusanganisa neyakajairwa. Izvi zvinyorwa zvakakodzera kunze kwehunyanzvi hwekunze masisita ayo anoshandiswa mvura, mafuta uye gasi peilline chigadzirwa chakagadzirirwa nekuzviita neoCocyanate ine zviitiko zvinotevera:
- Yakanaka compressive simba uye dimensional kugadzikana
- Yakakwira-sero-cell chiyero uye yakanaka mvura proproof kuita
- yakanaka insulation performance
