Donpipe 302 HCFC-141b puag muab polyols rau pipeline rwb thaiv tsev
Donpipe 302 HCFC-141b puag muab polyols rau pipeline rwb thaiv tsev
TAW qHIA
Cov khoom no yog ib hom ntawm muab polyols premixed nrog HCFC-141B, uas yog tshwj xeeb uas researched rau txhav PUF yuav tsim thermal rwb thaiv tsev kav. Nws yog dav siv nyob rau hauv chav kav, liquefied xwm roj khiav kav, roj kav thiab lwm yam liaj teb. Tus yam ntxwv raws li nram no:
(1) zoo flowability, los ntawm regulating mis kom haum txawv yeeb nkab diameters.
(2) rau yav tom ntej uas tsis muaj kub seem stability
