Donspray 502 HCFC-141b puag muab polyols
Taw qhia
DonSpray 502 yog cov tshuaj tsuag sib xyaw polyols nrog HCFC-141B ua tus neeg sawv cev tshuab, nws reacts nrog isocyanate los ua npuas dej uas muaj kev ua tau zoo, uas yog raws li hauv qab no,
1) zoo thiab uniformity cell
2) Tsawg thermal conductivity
3) zoo meej hluav taws kub
4) zoo heev tsis tshua muaj kub dimentional stability.
Nws siv rau txhua yam ntawm thermal rwb thaiv tsev tej yaam num uas siv cov tshuaj tsuag, xws li chav txias, lauj kaub loj, loj-scale pipelines thiab kev tsim kho tawm-phab ntsa los yog puab phab ntsa thiab lwm yam.
