ʻO Donspray 504 HFC-245fa i hui pū ʻia me nā polyols
OLELO HOOLAHA
ʻO DonSpray504 he polyols spray blend, he 245fa ka mea puhi puhi ma kahi o HCFC-141B, hana ia me ka isocyanate e hana i ka huʻa i loaʻa nā hana maikaʻi loa, e like me kēia.
1) nā pūnaewele maikaʻi a kūlike
2) haʻahaʻa thermal conductivity
3) pale ahi maikaʻi loa
4) maikaʻi haʻahaʻa-mahana dimensional paʻa.
Hoʻopili ia i nā ʻano ʻenehana insulation thermal a pau e hoʻohana ana i ka ʻenehana spray, e like me nā lumi anu, nā ipu hao, nā pipeline nui a me ke kūkulu ʻana metope etc.
