Donspray 504 HFC-245fa polyols boorish saldhig
HORDHAC
DonSpray504 waa buufin polyols boorish, buunankay wakiilka waa 245fa halkii HCFC-141B, waxa ay sameynayso la isocyanate in xumbo soo saarka taas oo uu leeyahay qaab aad u fiican, kuwaas oo ah sida soo socota,
1) aad u wanaagsan oo midayso unugyada
2) conductivity kaamerada hooseeyo
3) kaamil ah iska caabin olol
4) wanaagsan low-kulka xasiloonida waji leh.
Waxay khusaysaa dhammaan noocyada kala duwan ee injineernimada ningax kaamerada kaas oo isticmaala technology buufiyo, sida qolalka qabow, oo dheryay ku, dhuumaha baaxad weyn oo dhismaha metope iwm
