I-Donpipe 302 HCFC-141b ehlanganisa i-polyols yesisekelo sokufakwa kwamapayipi

I-Donpipe 302 HCFC-141b eyingxube yesisekelo se-polyols yokuvala amapayipi Isithombe Esifakiwe
  • I-Donpipe 302 HCFC-141b ehlanganisa i-polyols yesisekelo sokufakwa kwamapayipi
  • I-Donpipe 302 HCFC-141b ehlanganisa i-polyols yesisekelo sokufakwa kwamapayipi
  • I-Donpipe 302 HCFC-141b ehlanganisa i-polyols yesisekelo sokufakwa kwamapayipi

Incazelo emfushane:

Lo mkhiqizo uwuhlobo lwenhlanganisela ye-polyols exutshwe kuqala ne-HCFC-141B, ecutshungulwa ngokukhethekile i-PUF eqinile ukuze kukhiqizwe amapayipi okushisa ashisayo. Isetshenziswa kakhulu kumapayipi esitimu, amapayipi egesi yemvelo ewuketshezi, amapayipi kawoyela neminye imikhakha.

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 namadayamitha amapayipi ahlukene.

(2) okuhle kakhulu izinga lokushisa eliphansi ukuzinza ntathu
