Lithium Bromide (LiBr)
Lithium Bromide (LiBr), oo ah isku-dhis hygroscopic ah oo ka kooban lithium iyo bromine, ayaa si weyn loogu isticmaalaa codsiyada warshadaha iyo kiimikada sababtoo ah sifooyinka gaarka ah ee fiisikokemikaalkeeda. Waxaa lagu sameeyaa falcelinno sida daaweynta lithium carbonate oo lagu daweynayo hydrobromic acid ama ka falcelinta lithium hydroxide oo lagu daray bromine, taasoo soo saarta hydrates kristal ah oo ka duwan bromides-ka kale ee birta alkali.
LiBr waxay muujisaa milmi aad u fiican biyaha, khamriga, iyo ether, iyadoo xalalka biyaha ee xooggan ay muujinayaan cadaadis uumiga biyaha oo hooseeya. Hantidan, oo ay weheliso hygroscopicity-geeda sare, waxay ka dhigaysaa mid wax ku ool ah oo nadiifiya oo dareere ah, gaar ahaan qaboojinta nuugista iyo nidaamyada qaboojinta hawada. Intaa waxaa dheer, awooddeeda ay ku milmi karto isku-dhafka dabiiciga ah ee polar sida cellulose waxay ballaarinaysaa adeeggeeda hababka kiimikada ee gaarka ah, oo ay ku jiraan dehydrohalogenation catalytic ee sameynta olefin.
Daaweynta biyaha iyo codsiyada koritaanka kiristaalka, milmida LiBr iyo qaababka saafiga aadka u sarreeya (submicron/nanopowders) ayaa faa'iido leh. Bromide ion-ka waxaa lagu ogaan karaa xalalka biyaha iyadoo la adeegsanayo kaarboon disulfide iyo koloriin. Si kastaba ha ahaatee, maaraynta waxay u baahan tahay taxaddar: LiBr waxay dhalisaa kulayl weyn marka la milmo (sababtoo ah enthalpy taban oo xalka ah) waxayna keentaa khataro ah walax khafiif ah oo wax u dhimaysa maskaxda.
UrbanMines waxay siisaa LiBr darajooyin kala duwan (Mil Spec, ACS, Pharmaceutical, iwm.), xulashooyinka baakadaha, iyo nadiifnimada, iyagoo u hoggaansamaya heerarka ASTM, USP, iyo EP/BP. Taageerada farsamada, xogta badbaadada (MSDS), iyo qalabka beddelka cutubyada ayaa la bixiyaa si loo hubiyo adeegsiga badbaadada leh oo la hagaajiyay ee warshadaha oo dhan.

Maxaa loo isticmaalaa Lithium Bromide (LiBr)?
Lithium Bromide (LiBr)- Codsiyada iyo Isticmaalka
Lithium Bromide (LiBr) waa milix aan dabiici ahayn oo aad u milmi karta oo hygroscopic leh oo leh sifooyin heerkulbeeg iyo kiimiko oo gaar ah. Waa walax muhiim u ah qaboojinta tamarta ee baaxadda weyn waxayna u adeegtaa sidii falgal badan oo ku jira isku-darka kiimikada ee horumarsan. Lithium Bromide-keena saafiga ah ee sare, oo laga heli karo qaabab xal biyood oo adag iyo kuwa xooggan labadaba, waxaa loo sameeyay isku halaynta iyo waxqabadka codsiyada kala duwan.

Astaamaha Muhiimka ah & Faa'iidooyinka:
* Hygroscopicity-ga Gaarka ah: Aad waxtar ugu leh nuugista uumiga biyaha, taasoo ka dhigaysa mid ku habboon nuugista nuugista iyo qalajinta.
* Milmi Sare: Waxay muujisaa milmi aad u fiican oo ku jira dareeraha dabiiciga ah ee biyaha iyo kuwa cidhifyada, iyadoo bixinaysa dabacsanaan qaab-dhismeed.
* Xasiloonida Thermodynamic: Waxay bixisaa waxqabad la isku halleyn karo xaaladaha warshadaha ee adag, sida qaboojiyaha nuugista heerkulka sare.
* Waxyeelo Kala Duwan: Wuxuu u shaqeeyaa sidii kiciyaha, dhiirrigeliyaha, iyo wakiilka nadiifinta ee isku-darka kiimikada casriga ah.
Afeef: Lithium Bromide waa in si taxaddar leh loo maareeyaa, maadaama xalalka xooggan ay noqon karaan kuwo wax dumin kara. Waa mas'uuliyadda isticmaalaha inuu hubiyo dhaqamada maaraynta badbaadada leh iyo inuu go'aamiyo ku habboonaanta badeecadda ee codsigooda gaarka ah iyadoo la raacayo dhammaan xeerarka khuseeya.
