Potaziyamu kloridi (KCl) amagwiritsidwa ntchito pokonzekera mankhwala komanso ngati chowonjezera cha chakudya ndi mankhwala.Ndizotheka kuchepetsa sodium muzakudya zanu polowa m'malo mwa potassium chloride m'malo mwa mchere wa tebulo (sodium chloride), yomwe ingakhale yathanzi.Kusungunula potaziyamu kolorayidi amagwiritsidwanso ntchito electrolytic kupanga zitsulo potaziyamu.KCl imapezekanso m'madzi a m'nyanja yamchere ndipo imatha kuchotsedwa ku mineral carnallite.
Potaziyamu Chloride ndi chopatsa thanzi, chopatsa thanzi, komanso chothandizira chomwe chimakhala ngati makhiristo kapena ufa.imakhala ndi kusungunuka kwa 1 g mu 2.8 ml ya madzi pa 25 ° c ndi 1 g mu 1.8 ml ya madzi otentha.hydrochloric acid, ndi sodium kolorayidi ndi magnesium kolorayidi amachepetsa kusungunuka kwake m'madzi.amagwiritsidwa ntchito ngati cholowa m'malo mwa mchere ndi mchere.ali ndi mwayi wogwiritsa ntchito popanga zotsekemera zotsekemera komanso zosungira.amagwiritsidwa ntchito ngati gwero la potaziyamu kwa mitundu ina ya ma gels a carrageenan.amagwiritsidwa ntchito m'malo mwa sodium chloride muzakudya zotsika kwambiri za sodium.
Potaziyamu kolorayidi ndi labotale reagent ntchito kuonjezera kukhuthala kwa mankhwala mu zodzoladzola ndi mankhwala kukonzekera.
Potaziyamu chloride (KCl), yomwe imadziwika kuti muriate of potashi, ndiye gwero lodziwika bwino la potashi (K2O), ndipo limapanga pafupifupi 95% ya potashi padziko lonse lapansi.Pafupifupi onse (90%) potashi wamalonda amachokera ku magwero achilengedwe a mchere wa potaziyamu womwe umapezeka m'mabedi opyapyala m'mabeseni akulu amchere opangidwa ndi kutuluka kwa nyanja zakale.Masiku ano nyanja zamchere zamchere ndi mchere wachilengedwe zimayimira pafupifupi 10% ya potashi yonse yomwe imatha kubwezedwa.M'zigawo zimatsatiridwa ndi mphero, kutsuka, kuwunikira, kuyandama, crystallization, kuyenga ndi kuyanika.
Zoposa 90% za KCl zonse zimagwiritsidwa ntchito popanga feteleza.Kupanga kwa potaziyamu hydroxide kumapangitsa zoposa 90% zamafuta osagwiritsa ntchito feteleza kapena kugwiritsa ntchito mafakitale a KCl.KOH imagwiritsidwanso ntchito popanga feteleza wamadzi amtundu waulimi.Kugwiritsa ntchito KCl kumaphatikizapo:
Potaziyamu chloride (KCl) ndi mchere wosakhazikika womwe umagwiritsidwa ntchito popanga feteleza, chifukwa kukula kwa zomera zambiri kumachepa chifukwa cha kudya kwawo kwa potaziyamu.Potaziyamu muzomera ndiyofunikira pakuwongolera kwa osmotic ndi ionic, imagwira ntchito yofunika kwambiri m'madzi a homeostasis ndipo imalumikizidwa kwambiri ndi njira zomwe zimakhudzidwa ndi kaphatikizidwe ka mapuloteni.
Mu kujambula.Mu njira za buffer, ma electrode cell.
Potaziyamu kolorayidi angagwiritsidwe ntchito pokonza phosphate buffered saline, ndi m'zigawo ndi solubilization wa mapuloteni.
Amagwiritsidwa ntchito mu buffer mayankho, mankhwala, ntchito zasayansi, ndi kukonza chakudya.
Amagwiritsidwa ntchito muzakudya;gelling wothandizira;mchere wolowa m'malo;yisiti chakudya.
zakudya/zakudya zowonjezera: KCl imagwiritsidwa ntchito ngati chowonjezera chopatsa thanzi komanso/kapena chowonjezera chazakudya.KCl imagwiranso ntchito ngati chowonjezera cha potaziyamu pazakudya za ziweto.
KCl ndi yofunika achire wothandizira, amene ntchito makamaka pa matenda a hypokalemia ndi kugwirizana zinthu.Hypokalemia (kuchepa kwa potaziyamu) ndi vuto lomwe limatha kupha pomwe thupi limalephera kusunga potaziyamu wokwanira kuti ukhale wathanzi.
mankhwala a labotale: KCl imagwiritsidwa ntchito m'maselo a elekitirodi, mayankho a buffer, ndi ma spectroscopy.
kubowola matope kwa makampani opanga mafuta: KCl imagwiritsidwa ntchito ngati chowongolera mumatope obowola mafuta komanso ngati chokhazikika cha shale kuteteza kutupa.
zozimitsa moto ndi zozimitsa moto: KCl imagwiritsidwa ntchito ngati chigawo chazozimitsa moto chamankhwala owuma.
anti-freezing agents: KCl imagwiritsidwa ntchito kusungunula ayezi m'misewu ndi ma driveways.
Pafupifupi 4-5% ya potashi imagwiritsidwa ntchito m'mafakitale (UNIDOIFDC, 1998).Mu 1996, kuchuluka kwa potashi padziko lonse lapansi kunali pafupi ndi 1.35 Mt K2O.Zida zamafakitalezi ndi 98-99% zoyera, poyerekeza ndi ma potashi aulimi a 60% K2O osachepera (wofanana ndi 95% KCl).Potashi waku mafakitale akuyenera kukhala ndi osachepera 62% K2O ndipo akhale ndi milingo yotsika kwambiri ya Na, Mg, Ca, SO4 ndi Br.Potashi yapamwambayi imapangidwa ndi opanga ochepa padziko lonse lapansi.
Potaziyamu hydroxide (KOH), yomwe imadziwikanso kuti caustic potashi, ndiye chinthu chachikulu kwambiri cha K chosagwiritsa ntchito feteleza.Amapangidwa ndi electrolysis ya mafakitale KCl ndipo chimagwiritsidwa ntchito popanga sopo, zotsukira, mafuta, chothandizira, mphira kupanga, machesi, utoto ndi mankhwala.Caustic potashi imakhalanso ngati feteleza wamadzimadzi komanso ngati chophatikizira mu mabatire amchere ndi mankhwala opangira mafilimu.
Potaziyamu hydroxide ndi zopangira popanga mchere wa K osiyanasiyana, makamaka K carbonates, komanso citrate, silicates, acetates, ndi zina. Potaziyamu carbonate imapangitsa kumveka bwino kwa galasi motero imagwiritsidwa ntchito ngati magalasi abwino kwambiri, magalasi, magalasi abwino, magalasi owoneka bwino. , Chinaware ndi machubu a TV.Potaziyamu bicarbonate imagwiritsidwa ntchito kwambiri m'mafakitale azakudya ndi mankhwala.
Mankhwala opangidwa ndi potashi ndi mchere amagwiritsidwanso ntchito popanga zitsulo zachitsulo, nyama zochiritsidwa, zitsulo zowonongeka, zofukiza mapepala, zitsulo zolimba, bleaching agents, ufa wophika, kirimu wa tartar ndi zakumwa.Padziko lonse lapansi, KCl yamakampani ikuyembekezeka kugwiritsidwa ntchito motere: zotsukira ndi sopo, 30-35%;galasi ndi zoumba, 25-28%;nsalu ndi utoto 20-22%;mankhwala ndi mankhwala, 13-15%;ndi ntchito zina, 7-5% (UNIDO-IFDC, 1998).
Potaziyamu kloridi ndi reagent yomwe imagwiritsidwa ntchito kwambiri mu biochemistry ndi molecular biology.Ndi chigawo cha phosphate buffered saline (PBS, Product No. P 3813) ndi polymerase chain reaction (PCR) buffer (50 mM KCl).
KCl imagwiritsidwanso ntchito pofufuza za kayendedwe ka ion ndi potaziyamu.
KCl imagwiritsidwanso ntchito mu solubilization, kuchotsa, kuyeretsa, ndi crystallization ya mapuloteni.
Kugwiritsa ntchito KCl mu crystallization ya histone core octamers kwanenedwa.
