Mabda'a Shaqada ee Shaandhaynta dhoobada

Shaandheeyaha dhoobada wuxuu u shaqeeyaa iyada oo ku saleysan mabda'a ficilka ee capillary iyo micropore, waxay isticmaashaa ceramics microporous sida dhexdhexaadiyaha shaandhada, waxay isticmaashaa tiro badan oo ceramics microporous ah oo cidhiidhi ah, iyo qalabka kala soocida dareeraha adag ee loogu talagalay iyada oo ku saleysan mabda'a ficilka capillary.Shaydhiyaha disc ee ku jira cadaadiska xun ee shaqada ayaa isticmaala biyaha gaarka ah iyo sifooyinka hawada adag ee saxanka shaandhada microporous si ay u soo saaraan faakuumka gudaha gudaha ee saxanka shaandhada dhoobada oo ay dhaliyaan farqiga cadaadiska dibadda lagu dhajiyay saxanka shaandhada dhoobada ee hoos yimaada ficilka cadaadiska xun.Qalabka adag laguma dhexgalin karo dusha sare ee saxanka dhoobada iyada oo loo marayo saxanka filter dhoobada microporous, halka dareeraha uu si habsami leh u geli karo qalabka qaybinta dareeraha gaaska (foostada vacuum) ee dareeraha dibadda ama dib-u-warshadaynta sababtoo ah saameynta farqiga cadaadiska vacuum iyo hydrophilicity ee saxanka filter dhoobada, si loo gaaro ujeedada kala soocida dareeraha adag.

Qaabka iyo habka shaandhada dhoobada waxay la mid yihiin mabda'a shaqada ee filter vacuum disc, taas oo ah, iyadoo la raacayo ficilka kala duwanaanshaha cadaadiska, marka laalidu ay dhex maraan dhexdhexaadiyaha shaandhada, qaybaha waxaa lagu dhexqabaa dusha sare ee dhexdhexaadka ah samee keega shaandhada, dareeruhuna wuxuu ka soo baxaa dhex dhexaadiyaha shaandhada si loo gaaro ujeedada kala soocida dareeraha adag.Farqiga u dhexeeya ayaa ah in saxanka shaandhada dhexdhexaadka ah ee dhoobada ah uu leeyahay micropores kuwaas oo soo saara saamaynta capillary, si ay xoogga xididka ee micropores ka weyn tahay xoogga ay keento faakuum, sidaas darteed micropores mar walba waxaa ka buuxa dareere.Xaalad kasta ha ahaatee, saxanka filter-ka dhoobada ah ma ogola in hawada ay dhex marto.Sababtoo ah ma jirto hawo la dhex maro, isticmaalka tamarta inta lagu jiro kala-soocidda dareeraha adag waa mid hooseeya iyo heerka faakuumka ayaa sarreeya.
