Kubbadda dhoobada Porous ee dabool -hayaha iyo agabka taageeraya

Sharaxaad Gaaban:

Kubbadda dhoobada dhoobada ah ayaa sidoo kale loo yaqaan kubbadaha shaandhaynta. Waxaa lagu sameeyaa 20-30% daloolada gudaha kubadaha dhoobada ee aan firfircoonayn. Sidaa darteed looma adeegsan karo oo keliya taageeridda iyo daboolidda kiciyaha, laakiin sidoo kale shaandhaynta iyo baabi'inta wasakhda hadhuudhka, gelatin, asphalting, bir culus iyo ions birta oo ka yar 25um. Haddii kubbadda daloolka ah lagu dejiyo dusha sare ee fal -celiyaha, nijaasta ayaa ku guuldaraysata in laga takhaluso geeddi -socodkii hore waxaa lagu dhejin karaa daloolada kubbadaha dhexdooda, halkaasna waxaa laga ilaaliyaa kiciyaha oo la dheereeyaa wareegga hawlgalka ee nidaamka. Maaddaama nijaasta ku jirta agabku ay kala duwan tahay, adeegsaduhu wuxuu ku dooran karaa badeecada cabbirkooda, daloolada iyo porosity -ka, ama haddii loo baahdo, ku dar molybdenum, nikkel iyo cobalt ama qaybo kale oo firfircoon si looga hortago soo -kiciyaha in uu coking ama sumeeyo.
