Donspray 504 HFC-245fa puag muab polyols
TAW qHIA
DonSpray504 yog tsuag muab polyols, tshuab neeg uas sawv cev 245fa es tsis txhob ntawm HCFC-141B, nws reacts nrog isocyanate rau khoom ua npuas ncauj uas muaj zoo heev nrug, uas yog raws li nram no,
1) zoo thiab uniformity hlwb
2) tsis muaj thermal conductivity
3) zoo meej nplaim kuj
4) zoo uas tsis muaj-kub seem stability.
Nws siv rau tag nrho cov hom ntawm thermal rwb thaiv tsev engineering uas siv cov tshuaj tsuag technology, xws li mob khaub thuas chav, huam, loj-scale pipelines thiab siv Metope etc.
