I-Donpipe 302 HCFC-141b ehlanganisa i-polyols yesisekelo sokufakwa kwamapayipi
ISINGENISO
Lo mkhiqizo uwuhlobo lwenhlanganisela ye-polyols exutshwe kuqala ne-HCFC-141B, ecutshungulwa ngokukhethekile i-PUF eqinile ukuze kukhiqizwe amapayipi okushisa ashisayo.Isetshenziswa kabanzi kumapayipi esitimu, amapayipi egesi emvelo ane-liquefied, amapayipi kawoyela neminye imikhakha.Izici zimi kanje:
(1) ukugeleza okuhle, ngokulawula ifomula ukuze ivumelane nobubanzi obuhlukene bamapayipi.
(2) izinga lokushisa eliphansi lokuzinza kwe-dimensional elihle kakhulu
