Junda Boehmite
Soo Bandhigidda Alaabta
Junda waxay bixisaa faylal balaadhan oo ah alaabta boehmite
Qalabka ayaa marka hore lagu kala soocaa dispersibility.Junda waxay bixisaa alaabooyin kala duwan oo ka mid ah kuwa aad u sarreeya, darajada xidhitaan, PB950, si ay u kala qaybiyaan yar, fasalka extrusion, PB250A iyo PB150. Oo wuxuu leeyahay sifooyinka daahirsanaanta sare, qaybinta xajmiga cidhiidhiga ah, kala firidhsan wanaagsan , xasilloonida dufcaddii wanaagsan, iwm, waxaa si ballaaran loo isticmaali karaa in olol retardant, daahan tamarta cusub diaphragm batari, lithium dahaarka xaashida electrode batari, saxan dahaarka naxaas ah, abrasive polishing iyo beeraha kale.
Fasal kasta oo maaddada ah ayaa lagu heli karaa noocyo kala duwan oo muhiim ah oo la beddeli karo, oo qeexaya sifooyinka sida cabbirka crystal, qaybinta mugga daloolka, iyo cabbirka qaybta. codsi gaar ah.
Waxqabadka alaabta
Taxanaha alaabooyinka waxay leeyihiin cabbirka qayb yar, mugga daloolka sare, aagga dusha sare ee gaarka ah, milanka jel wanaagsan, nadiifinta crystal sare, content wasakh hoose. Waxay leedahay sifooyinka gel thixotropic.
Waxqabadka alaabta
1, oo loo isticmaalo sidii batroolka iyo sifaynta warshadaha kicinta iyo isku dhafka shaandhada molecular ee isha aluminium
Pseudo-boehmite waxaa inta badan loo isticmaalaa sidii xire loogu talagalay kicinta dildilaaca catalytic. Pseudo-boehmite sida binder ma hagaajin karo oo kaliya xoogga kicinta, laakiin sidoo kale hagaajin qaybinta xajmiga dalool ee kicinta, hagaajinta kuleyl iyo hydrothermal xasilloonida kicinta, hagaajin cufnaanta acid xarunta firfircoon ee kicinta, iyo hagaajinta dhaqdhaqaaqa catalytic.
2. Loo isticmaalo sidii taageero kicin
Boehmite waxaa si weyn loogu isticmaalaa taageerada kimikalka, nadiifinta saliidda iyo falcelinta batroolka. Tusaalooyinka caadiga ah waxaa ka mid ah taageerada kicinta biyo-refining, dib-u-habaynta taageerada kicinta, taageerada kicinta methanation, iwm. Pseudo-boehmite sidoo kale waxaa loo isticmaali karaa kicin si ay u noqoto γ-alumina ka dib fuuqbaxa.
