Donspray 504 HFC-245fa saldhigga isku dhafka polyols
Donspray 504 HFC-245fa saldhigga isku dhafka polyols
HORDHAC
DonSpray504 waa polyols isku dhafan oo buufin ah, wakiilka afuufaya waa 245fa halkii HCFC-141B, waxay la falgashaa isocyanate si ay u soo saarto xumbo leh qaab ciyaareed heer sare ah, kuwaas oo ah sida soo socota.
1) unugyo fiican oo isku mid ah
2) conductivity kaamerada hoose
3) caabbinta olol qumman
4) xasilooni cabbir heerkul hoose oo wanaagsan.
Waxay khusaysaa dhammaan noocyada injineerada dahaadhka kulaylka ee adeegsada tignoolajiyada buufinta, sida qolalka qabow, dheryaha, dhuumaha waaweyn iyo qaabka dhismaha iwm.
