Xaaladaha isticmaalka ee molybdenum silig kululaynta inta badan waxaa ka mid ah deegaanka isticmaalka, size iyo design qaab, doorashada iska caabin ah, iyo habka rakibo.
Deegaanka la isticmaalo: Silig kuleyliyaha Molybdenum waxaa badanaa lagu isticmaalaa meel faaruq ah ama gaas aan shaqaynayn oo la ilaaliyo, sida qalabka heerkulka sare sida foornooyinka faakuumka. Doorashada deegaankani waxay gacan ka geysaneysaa in la ilaaliyo xasilloonida fiilada kuleylka molybdenum waxayna kordhisaa nolosha adeegga.
Cabbirka iyo qaabka qaabaynta: Baaxadda iyo qaabka xariijinta kuleylka molybdenum waxay u baahan tahay in la go'aamiyo iyadoo loo eegayo xajmiga iyo qaabka gudaha ee foornada faakuumka si loo hubiyo inay si isku mid ah u kululayn karto alaabta gudaha foornada. Isla mar ahaantaana, qaabka xariijinta kuleylka molybdenum waxay sidoo kale u baahan tahay inay tixgeliso meelaynta walxaha iyo dariiqa haynta kulaylka si loo hagaajiyo waxtarka kuleylka.
Xulashada caabbinta: Iska caabbinta xariijimaha kuleylka molybdenum waxay saameyn doontaa saameynteeda kuleylka iyo isticmaalka tamarta. Guud ahaan, hoos u dhigista iska caabbinta, ayaa si fiican u saameynaysa kuleylka, laakiin isticmaalka tamarta ayaa sidoo kale kordhin doona si waafaqsan. Sidaa darteed, habka naqshadeynta, waxaa lagama maarmaan ah in la doorto caabbinta ku habboon ee ku salaysan baahiyaha dhabta ah.
Habka Rakibaadda: Xarigga kuleyliyaha molybdenum waa in lagu dhejiyaa barkinta gudaha foornada faakuumka oo lagu hayaa masaafo gaar ah si uu kulaylka u baabi'iyo. Isla mar ahaantaana, waa in fiiro gaar ah loo yeesho ka hortagga xiriir toos ah oo u dhexeeya xariijinta kuleylka molybdenum iyo darbiga foornada si looga fogaado wareegyada gaaban ama kulaylka.
Xaaladahan isticmaalku waxay xaqiijinayaan waxtarka iyo badbaadada fiilooyinka kuleylka molybdenum ee deegaanno gaar ah, iyagoo sidoo kale bixinaya dammaanad qaadka codsigooda deegaan heerkul sare ah.
Waqtiga ay ku qaadanayso foornada siliga molybdenum si ay ugu kululaato 1500 darajo Celsius way kala duwanaan kartaa iyadoo ku xiran foornada gaarka ah, awooddeeda iyo heerkulka hore ee foornada. Si kastaba ha ahaatee, waxaa guud ahaan lagu qiyaasaa in foornada kuleylkeedu sarreeyo oo awood u leh in ay gaarto 1500 darajo Celsius ay qaadan karto ku dhawaad 30 ilaa 60 daqiiqo si ay uga soo kabsato heerkulka qolka ilaa heerkulka shaqada ee loo baahan yahay.
Waxaa xusid mudan in waqtiyada kuleylka ay saameyn ku yeelan karaan arrimo ay ka mid yihiin cabbirka foornada iyo dahaarka, gelinta tamarta, iyo walxaha gaarka ah ee kuleylka la isticmaalo. Intaa waxaa dheer, heerkulka bilowga ah ee foornada iyo xaaladaha deegaanka ee deegaanka ku hareeraysan ayaa sidoo kale saameeya wakhtiga kuleylka.
Si loo helo waqtiyo kuleyl oo sax ah, waxaa lagu talinayaa in la tixraaco qeexida soo saaraha iyo tilmaamaha foornada molybdenum ee gaarka ah ee la isticmaalayo.
Gaaska ugu fiican ee foornooyinka siliga molybdenum caadi ahaan waa hydrogen saafi ah oo sarreeya. Sababtoo ah hydrogen waa mid aan firfircooneyn oo yareyn, waxaa badanaa loo isticmaalaa foornooyinka kulaylka sare ee molybdenum iyo biraha kale ee soo noqnoqda. Marka loo isticmaalo jawiga foornada, hydrogen waxay ka caawisaa ka hortagga oksaydhka iyo faddaraynta fiilada molybdenum heerkulka sare.
Isticmaalka hydrogen-nadiifinta sare waxay caawisaa abuurista jawi nadiif ah oo la kantaroolo foornada dhexdeeda, taas oo muhiim u ah ka hortagga oksaydhyada inay ku sameeyaan siliga molybdenum xilliga kuleylka. Tani waxay si gaar ah muhiim u tahay sababtoo ah molybdenum waxay si sahal ah u oksijiinta heerkulka sare, iyo joogitaanka ogsijiinta ama gaasaska kale ee falcelinta waxay yareyn kartaa waxqabadkeeda.
Waxaa muhiim ah in la hubiyo in hydrogen-ka la isticmaalo uu yahay nadiif sare si loo yareeyo khatarta wasakheynta iyo ilaalinta sifooyinka loo baahan yahay ee siliga molybdenum. Intaa waxaa dheer, foornada waa in loo qaabeeyaa si badbaado leh oo loo xakameeyo socodka hydrogen si loo hubiyo hawlgal badbaado leh. Markaad isticmaalayso hydrogen ama gaas kasta foornada molybdenum, had iyo jeer raac tilmaamaha soo saaraha iyo talooyinka badbaadada.
