Donpipe 302 HCFC-141b tushe saje polyols ga bututun rufi
GABATARWA
Wannan samfurin ne mai irin saje polyols premixed da HCFC-141B, wanda aka musamman gudanar da bincike don m PUF don samar da thermal rufi bututu. An yadu amfani da tururi bututu, liquefied halitta gas a guje bututu, mai bututu da kuma sauran filayen. A halaye su ne kamar haka:
(1) mai kyau flowability, ta gudãnar dabara don dacewa daban-daban bututu diameters.
(2) m low zazzabi girma kwanciyar hankali
