Donfoam 824PIR HFC-245fa base musanganiswa polyols inoenderera PIR block furo
NHUNGAMIDZO
DonFoam 824/PIR imhando yekusanganisa polyols inoshandisa hfc-245fa foaming agent, ine polyol seyakanyanya mbishi zvinhu, yakasanganiswa neyakakosha mubatsiri mumiriri, yakakodzera kuvharwa kwekuvaka, chekufambisa, goko uye zvimwe zvigadzirwa.Ichi chinyorwa chakanyatsogadzirirwa kuenderera mberi mutsara .Chigadzirwa che polyurethane chakagadzirirwa nekuchigadzirisa ne isocyanate chine zvinotevera zvakanakira:
- Eco-hushamwari, pasina kuparadza ozone layer
- Yakakwira yekumanikidza simba uye yakanaka homogeneity ye isotropic simba
-- Yakanakisa thermal insulation performance uye dimensional kugadzikana
