Potassium chloride (KCl) waxaa loo isticmaalaa diyaarinta daroogada iyo sidii cunto lagu daro iyo reagen kiimikaad.Waa suurtogal in la yareeyo soodhiyamka cuntadaada adiga oo ku beddelaya potassium chloride milixda miiska (sodium chloride), kaas oo laga yaabo in uu ka caafimaad badan yahay.chloride potassium-ka dhalaalaysa ayaa sidoo kale loo isticmaalaa soo saarista elektrolytka ee potassium macdan ah.KCl sidoo kale waxaa laga helaa brine biyaha badda waxaana laga soo saari karaa carnallite macdanta.
Potassium Chloride waa nafaqo, kaabis cunto, iyo wakiilka gelling ee u jira sida crystals ama budo.waxay leedahay milmi 1 g 2.8 ml oo biyo ah 25°c iyo 1 g 1.8 ml oo biyo ah karkaraya.hydrochloric acid, iyo sodium chloride iyo magnesium chloride waxay yareeyaan milanka biyaha.Waxa loo isticmaalaa beddelka milixda iyo kaabista macdanta.waxay leedahay isticmaalka ikhtiyaari ah ee jelly macaan oo macmal ah iyo kaydinta.waxa loo isticmaalaa sida isha potassium ee noocyada qaar ka mid ah jeelka carrageenan.waxaa loo isticmaalaa in lagu beddelo sodium chloride ee cuntooyinka sodium-yar.
Potassium chloride waa reagent shaybaar oo loo isticmaalo in lagu kordhiyo viscosity sheyga ee isqurxinta iyo diyaarinta daawooyinka.
Potassium chloride (KCl), oo loo yaqaan muriate of potash, ayaa ah isha ugu badan ee laga helo potash (K2O), waxayna ka tahay qiyaastii 95% wax soo saarka potash-ka adduunka.Ku dhowaad dhammaan (90%) potash-ganacsiyeedka ayaa laga soo saaraa ilaha dabiiciga ah ee kaydka milixda potassium ee ku dhaca sariiraha khafiifka ah ee ku dhex yaal barkadaha milixda ee waaweyn ee ay sameeyeen uumi-baxa badaha hore.Harooyinka milixda ee wakhtigan iyo brines-ka dabiiciga ah waxay ka dhigan yihiin 10% wadarta guud ee potash la soo kaban karo.Soo saarista waxaa ku xiga wax-shiidid, dhaqid, baaris, sabbeyn, crystallization, sifeyn iyo qallajin.
In ka badan 90 % wadarta guud ee isticmaalka KCl waxa loo isticmaalaa soosaarka bacriminta.Soo saarista potassium hydroxide waxay ka dhigan tahay in ka badan 90 % isticmaalka aan bacriminta ahayn ama warshadaha ee KCl.KOH waxa kale oo loo isticmaalaa soo saarista qaar ka mid ah bacriminta dareeraha heerka-beeraha.Isticmaalka KCl waxaa ka mid ah:
Potassium chloride (KCl) waa milix aan organic ahayn oo loo isticmaalo samaynta bacriminta, maadaama koritaanka dhir badan ay xaddidan tahay qaadashada potassium.Potassium ee dhirta ayaa muhiim u ah nidaamka osmotic iyo ionic, waxay door muhiim ah ka ciyaartaa homeostasis biyaha waxayna si dhow ula xiriirtaa hababka ku lug leh isku-darka borotiinka.
Sawir qaade.Xallinta kaydinta, unugyada korantada.
Potassium chloride waxa loo isticmaali karaa diyaarinta phosphate buffered salineed, iyo soo saarista iyo milanka borotiinada.
Loo isticmaalo xalalka kaydinta, daawada, codsiyada sayniska, iyo habaynta cuntada.
Loo isticmaalo nafaqeynta;wakiilka jelling;beddelka milixda;cuntada khamiirka.
Cunnooyinka/cuntooyinka lagu daro: KCl waxa loo isticmaalaa nafaqayn iyo/ama cunto lagu daro cunto ahaan.KCl waxay sidoo kale u adeegtaa sidii kabka potassium ee quudinta xoolaha.
Alaabooyinka dawooyinka: KCl waa wakiil daawayn oo muhiim ah, kaas oo inta badan loo isticmaalo daawaynta hypokalemia iyo xaaladaha la xidhiidha.Hypokalemia (yaraanta potassium) waa xaalad halis ah oo jirku ku guuldareysto inuu hayo potassium ku filan si uu u ilaaliyo caafimaadka.
kiimikooyinka shaybaadhka: KCl waxaa loo isticmaalaa unugyada elektiroonigga ah, xalalka kaydinta, iyo spectroscopy.
qodista dhoobada warshadaha wax soo saarka saliida: KCl waxaa loo isticmaalaa sidii qaboojiyaha dhoobada qodista saliidda iyo xasilinta shale si looga hortago bararka.
dab-demiska iyo walxaha ka-hortagga dabka: KCl waxa loo isticmaalaa qayb ahaan dab-demiska kiimikada engegan.
wakiilada qaboojinta: KCl waxaa loo isticmaalaa in lagu dhalaalliyo baraf waddooyinka iyo waddooyinka.
Qiyaastii 4-5% wax-soo-saarka potash waxaa loo isticmaalaa codsiyada warshadaha (UNIDOIFDC, 1998).Sannadkii 1996-kii, sahayda adduunka ee heerka wershadaha potash wuxuu ku dhowaa 1.35 Mt K2O.Qalabkan warshaduhu waa 98-99% saafi ah, marka la barbar dhigo qeexida potash-beeraha ee 60% K2O ugu yaraan (oo u dhiganta 95% KCl).Potash-ka warshaduhu waa inuu ka kooban yahay ugu yaraan 62% K2O waana inuu leeyahay heerar aad u hooseeya oo Na, Mg, Ca, SO4 iyo Br.Potash-kan heerka sare ah waxa soo saara dhawr-soosaarayaal adduunka oo dhan ah.
Potassium hydroxide (KOH), oo sidoo kale loo yaqaan potassium caustic, waa badeecada ugu weyn ee K ee isticmaalka aan bacriminta ahayn.Waxaa soo saara korantada ee warshadaha KCl waxaana si weyn loogu isticmaalaa soo saarista saabuunta, saabuunta, dufanka, kicinta, caagga synthetic, taraq, midabada iyo cayayaanka.Potash-ka Caustic sidoo kale waa sida bacriminta dareeraha ah iyo sida qayb ka mid ah baytariyada alkaline-ka iyo kiimikooyinka farsamaynta filimada sawirada.
Potassium hydroxide waa wax cayriin in wax soo saarka ee cusbada K kala duwan, inta badan K carbonates, iyo sidoo kale citrates, silicates, acetates, iwm. , chinaware iyo tuubooyinka TV-ga.Potassium bicarbonate waxaa inta badan loo isticmaalaa cuntada iyo warshadaha dawooyinka.
Iskudhisyada Potash-ka laga keeno iyo cusbada ayaa sidoo kale loo isticmaalaa soo saarista qulqulka birta, hilibka la daweeyay, birta kulul, qiiqa waraaqaha, birta adag, walxaha warankiila, budada dubista, kareemka tartar iyo cabitaanada.Adduunka oo dhan, warshadaha KCl waxaa lagu qiyaasaa in loo isticmaalo sida soo socota: saabuunta iyo saabuunta, 30-35%;dhalooyinka iyo ceramics, 25-28%;dharka iyo dheeha 20-22%;kiimikooyinka iyo daroogooyinka, 13-15%;iyo isticmaalka kale, 7-5% (UNIDO-IFDC, 1998).
Potassium chloride waa reagent aad loogu isticmaalo bayoolaji iyo bayoolaji molecular.Waa qayb ka mid ah cusbada phosphate buffered (PBS, Product No. P 3813) iyo falcelinta silsiladda polymerase (PCR) kaydiyaha (50 mM KCl).
KCl waxaa sidoo kale loo isticmaalaa daraasadaha gaadiidka ion iyo kanaalada potassium.
KCl waxa kale oo loo adeegsadaa solubilization, saarista, nadiifinta, iyo crystallization ee borotiinada.
Isticmaalka KCl ee crystallization of histone core octamers ayaa la soo sheegay.
