Donspray 502 HCFC-141b garo sanganisa polyols
NHANGANYAYA
DonSpray 502 iri mwaya mubatanidzwa polyols pamwe HCFC-141B sezvo anoridza mumiriri, izvozvo zvaanoita pamwe isocyanate kune zvibereko furo rine zvesimba zvakaisvonaka, izvo zviri sezvinotevera:
1) akanaka uye zvakafanana masero
2) pasi chafariz conductivity
3) akakwana moto nemishonga
4) kwazvo pasi tembiricha dimentional pakusimba.
Pachirehwa ose kumbogadzirwa kuti mudziye muzvirongwa izvo vanoshandisa pfapfaidzo, akadai pachando makamuri, makuru hari, pamwero mukuru mapaipi uye kuvakwa kunze-rusvingo kana mukati-rusvingo etc.
