Donspray 504 HFC-245fa garo sanganisa polyols
NHANGANYAYA
DonSpray504 ndiye mwaya mubatanidzwa polyols, anoridza mumiririri ndiyo 245fa panzvimbo HCFC-141B, izvozvo zvaanoita pamwe isocyanate kune zvibereko furo rine zvesimba zvakaisvonaka, izvo zviri sezvinotevera:
1) akanaka uye zvakafanana masero
2) pasi chafariz conductivity
3) akakwana murazvo nemishonga
4) chakanaka yakaderera-tembiricha ndeiya yakaita pakusimba.
Pachirehwa ose kumbogadzirwa kuti mudziye okugadzira rinoshandisa pfapfaidzo michina, akadai pachando makamuri, nehari, pamwero mukuru mapaipi uye kuvakwa metope etc.
