Nikkel waa bir muhiim ah oo aan bacrin ahayn oo leh adeegsi badan.Waxay inta badan ku dhacdaa nikkel sulfide iyo macdanta nikkel oxide ee dabiiciga ah.30% kheyraadka nikkelku waa macdan sulfide halka 70% ay yihiin macdanta nikkel-ka dambe.Iyada oo ay sii kordhayso baahida loo qabo nikkel iyo hoos u dhaca tartiib tartiib ah ee macdanta nikkel sulfide, horumarinta macdanta nikkel dambe waxay muujinaysaa isbeddel xoog leh.Habka sulfuric acid kala-goynta macdanta nikkel-ka dambe, hadhaaga qashinka nikkel-ka dambe waxa uu noqday arrin xaddidaysa habka soo saarista nikkel qoyan.Sida soo saaraha eenikkel dharbaaxowarshad shiidi toosan, HCMilling(Guilin Hongcheng) ayaa kuu soo bandhigi doonta hababka soo kabashada iyo dib u isticmaalida qashinka dambe ee nikkel ore hoos.
Habka soo kabashada iyo dib-u-isticmaalka hadhaaga qashinka nikkel-ka dambe waa in la nadiifiyo qashinka qashinka nikkel-ka dambe ee 160 ~ 900 ℃ 20 ~ 120 min, ka dib qaboojinta dabiiciga ah, ku shiiddo walxo budada ah oo leh 0.08 mm hadhaaga shaandho ka yar 10% iyada oo loo marayo nikkel dharbaaxowarshad shiidi toosansi aad u diyaarisid wax cayriin ah oo ah sibidhka magnesium, wax lagu daaweeyo saldhigga wadada ama rinjiga dhismaha darbiga.Tallaabooyinka gaarka ah ee soo kabashada iyo dib-u-isticmaalka nikkel ore slag dambe waa sida soo socota:
(1) The nickel slag leh content qoyaan ah 12% ~ 18% (qaybaha ganaax ee ka hooseeya 3 mm xisaabaadka in ka badan 70%, iyo viscosity waa xoog) waxaa la qalajiyey by qallajiye degdeg ah karkaraya, content qoyaan la dhimay in ka yar. 3%, ka dibna waxaa la geliyaa kaydinta ka dib daawaynta ka saarista birta ee marxaladaha badan, iyo maaddooyinka ayaa lagu ridayaanikkel dharbaaxoshiidid.
(2) Dharka nikkel ee la qalajiyey waxaa lagu quudiyaa nikkel slag milix si ay u soo baxaan oo u jajabiyaan ka dib marka la isku daro (ku dar qadar ku habboon ee firfircoonida), ka dibna waxaa lagu kala saaraa kala-soocidda hawada.Qaybaha aan fiicneyn ayaa lagu soo celiyaanikkel dharbaaxotoosanrullaluistemadkawarshad, iyo budada ganaaxa ee soo hartay waxay gashaa qulqulka budada ee dabaysha si ay u diyaariso alaabta la dhammeeyey, ka dibna lagu dhejiyo kaydinta.Budada aan fiicneyn ee leh meel gaar ah oo ah<200m2/kg ayaa lagu celiyaa nikkel slag toosan wax shiida ka dibna la jajabiyey.Qaar ka mid ah budada aadka u fiican ee leh meel gaar ah oo gaar ah>450m2/kg waxaa aruuriya boodhka aruuriya ka dibna si toos ah ayaa loogu qaadaa bakhaarka alaabta la dhammeeyay.
Qashinka qashin-qubka ee nikkel-ka dambe waa isku dhafka calcium sulfate, magnesium hydroxide, calcium silicate hydrate iyo calcium aluminate hydrate.Kadib qalajinta ama caleenta heerkulka hooseeya, isku dhafka calcium sulfate anhydrous, magnesium oxide, dicalcium silicate iyo calcium aluminate ayaa la helaa.Waxay leedahay sifooyinka guud ee Portland cement, sibidhka magnesite iyo gypsum.Waa nooc cusub oo shamiito ah oo si balaadhan looga isticmaalo warshadaha dhismaha.Habka soo kabashada iyo dib-u-isticmaalka qashinka qashinka nikkel-ka dambe waa mid sahlan, kuma jiraan heerkul sare, cadaadis sare iyo qalab qaali ah, waana sahlan tahay in la hirgeliyo.Habkanikkel dharbaaxotoosanrullaluistemadkawarshadwaa tallaabada ugu muhiimsan ee dib u soo kabashada, dib-u-isticmaalka iyo ka faa'iidaysiga kheyraadka ee nikkel dambe, xisaabinta qiyaastii kala bar wadarta isticmaalka tamarta, si loo yareeyo kharashka wax soo saarka, isticmaalka tamarta iyo hagaajinta waxtarka nickel slag shiidid.Waxaan kugula talineynaa inaad dooratid nikkel ore-shiid kiimikaad toosan si aad u bedesho mashiinka kubbadda cagta ee dhaqanka ah oo ah qalabka ugu muhiimsan ee soo kabashada iyo dib u isticmaalka nikkel ore slag dambe.Thenikkel dharbaaxo ultra-gacanwarshadhabka of nikkel dharbaaxowarshad shiidi toosan waa la qaatay, iyo ganaaxa shiidi ku habboon waxaa lagu gaaraa iyadoo si macquul ah loo hagaajinayo kala soocida si loo hubiyo in wax soo saarka budo ultra-fine leh meel dusha gaar ah oo buuxinaya shuruudaha xoogga iyo hawlaha hoos isticmaalka awood yar, si looga fogaado dhibaatada of content budo ganaax xad-dhaaf ah. ama isticmaalka tamarta sare ee ay keento ifafaalaha shiidaalka badan ee kubbadda qadiimiga ah.
HLM taxanaha nikkel slagwarshad shiidi toosan ay soo saartay HCMilling (Guilin Hongcheng) ayaa si weyn loogu isticmaalay noocyada kala duwan ee qashinka dib-u-warshadaynta iyo dib-u-warshadaynta si loo soo saaro walxaha sibidhka cagaaran, iyada oo siinaya taageero qalab wanaagsan oo dib u soo kabashada iyo dib-u-isticmaalka qashinka qashinka nikkel-ka dambe.Haddii aad qabto baahida dib-u-warshadaynta qashinka nikkel ore iyo nikkel dharbaaxoshiidid, fadlan kala xidhiidh HCM si aad u hesho faahfaahinta qalabka.
