Donspray 502 HCFC-141b puag muab polyols
TAW qHIA
DonSpray 502 yog tsuag muab polyols nrog HCFC-141B li tshuab neeg sawv cev, 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 hluav taws kuj
4) zoo heev uas tsis muaj kub dimentional stability.
Nws siv rau tag nrho cov hom ntawm thermal rwb thaiv tsev tej yaam num uas siv cov tshuaj tsuag, xws li mob khaub thuas chav, loj huam, loj-scale pipelines thiab siv tawm-phab ntsa los yog puab phab ntsa thiab lwm yam
