Yini i-lanthanum carbonate futhi uhlelo lokusebenza, umbala?

I-Lanthanum Carbonate(i-lanthanum carbonate), ifomula yamangqamuzana leLa2 (CO3) 8H2O, ngokuvamile iqukethe inani elithile lama-molecule amanzi. Luhlelo lweRhmbohedral Crystal System, lungasabela ngama-acid amaningi, i-solubility 2.38 × 10-7mol / l emanzini ngo-25 ° C. Kungaba ukubola ngokushisayo kube yi-lanthanum trioxide ngo-900 ° C. Enqubweni yokubola okushisayo, kungakhiqiza u-Alkali. Esezinhlelweni zokubola okushisayo kungakhiqiza u-Alkali.I-Lanthanum CarbonateKungenziwa nge-ALKALI Metal Carbonates ukwakha usawoti omnandi wamanzi we-carbonate.I-Lanthanum CarbonateI-Precipitate ingenziwa ngokungeza i-ammonium carbonate ethe xaxa kwikhambi le-dilute likasawoti we-soluble lanthanum usawoti.

Sebenzisa:.I-Lanthanum CarbonateI-Inorganic Compound eyakhiwa nge-lanthanum element ne-carbonate ion. Kuboniswa ukuqina okuqinile, ukusongela okuphansi kanye nezakhiwo zamakhemikhali ezisebenzayo. Embonini, iLanthanum Carbonate ingasetshenziswa kabanzi kuma-ceramics, ama-elekthronikhi, umuthi kanye nezinye izinkambu. Phakathi kwazo, uLanthanum Carbonate udlala indima ebalulekile embonini ye-ceramics, angasetshenziswa njenge-pigment, glaze, izithasiselo zengilazi, njll.; Emkhakheni we-elekthronikhi, i-lanthanum carbonate ingalungiswa nge-high kagesi esebenza ngogesi, ukoniwa okushisa okuphansi kwezinto zokwakha eziqinile, ezilungele ukukhiqizwa kwama-capacitors aphezulu wamandla, asetshenziswa ekwengezelweni kwama-catalysts aseThernary, ama-carbide angezeli; Emkhakheni wezemithi,I-Lanthanum Carbonateisengezo esivamile emithini, futhi ingasetshenziselwa ukwelapha emkhakheni wezokwelapha,I-Lanthanum CarbonateIngabe isengezo sezidakamizwa esivamile, esingasetshenziselwa ukwelashwa kwe-hypercalcemia, i-hemolytic uremic syndrome nezinye izifo, futhi ilungele ukwelashwa kwe-hyperphosphatemia ezigulini zezifo ze-End-Stage Renal. Ngezwi,I-Lanthanum CarbonateInemisebenzi eminingi futhi isetshenziswa kabanzi embonini yamakhemikhali yanamuhla, isayensi yezinto ezibonakalayo, umuthi kanye nezinye izinkambu.

Ukufaka ndawonye: 25, 50 / Ama-KG, 1000kg / tonne esikhwameni sokwehla, 25, 50kg / umgqomo ekhadinibhodi.

Ungakhiqiza kanjani:

I-Lanthanum Carbonateyindawo eyinhloko yokukhiqizwa kweLanthanum oxide [1-4]. Ngokwesimo esiphuthumayo sokuvikelwa kwemvelo, i-ammonium bicarbonate, njengento yendabuko yokulungiselela i-lanthanum carbonate, isetshenziselwe ikakhulukazi ekukhiqizeni kwezimboni [5-7], yize inezinzuzo zezindleko eziphansi zokukhiqiza nokungcola okuphansi kwe-carbonate etholakele. Kodwa-ke, ngenxa yokuphazamiseka kwe-NH + 4 kumanzi angcolile wezimboni, okunomthelela omkhulu emvelweni, inani le-ammonium usawoti osetshenziswe embonini selibekwe phambili izidingo eziqinile. Njengomunye wabaphambili, i-sodium carbonate, uma iqhathaniswa ne-ammonium bicarbonate, lapho kulungiswalanthanum carbonate in Inqubo yamanzi angcolile wezimboni ngaphandle kwe-ammonia, ukungcola kwe-nitrogen, okulula ukubhekana nakho; Uma kuqhathaniswa ne-sodium bicarbonate, ukuzivumelanisa nemvelo kunamandla [8 ~ 11].I-Lanthanum Carbonatenge-sodium carbonate njenge-precipitant yokulungiswa kwe-lodium emhlabeni ephansi i-carbonate akuvamile ukubikwa ezincwadini, ezisebenzisa ukusebenza okuthe xaxa kwendlela yokudla yemvula, ne-sodium ephansiI-Lanthanum Carbonateilungiselelwe ukulawula uchungechunge lwezimo zokuphendula.

Izindlela zokutholwa zokuhamba zeI-Lanthanum Carbonate: Izimoto zokuhamba kufanele zifakwe izinhlobo ezifanele kanye nenani lemishini yokulwa nomlilo nemishini yokwelashwa okuvuzayo. Kuvinjelwe ngokuphelele ukuxuba nokuhambisa ngama-oxidizers namakhemikhali adliwayo. Ipayipi eliphumayo lemoto ethwala izimpahla - idinga ukufezekiswa i-flame retardant. Lapho amaloli e-tanker esetshenziselwa izinto zokuhamba, kufanele kufakwe amaketanga emhlabathini. Ukuze unciphise ugesi ovuthiwe owenziwe nge-vibration, kungenzeka ukufaka izihlukanisi ze-hole ethangini. Kwenqatshelwe ukulayisha noma ukulayisha imishini emishini namathuluzi athambekele ezinhlathini. Ehlobo ekuseni nasekuseni kusihlwa kulungile, kuyinqubo yokuhamba, ukuvikela ilanga nemvula kanye nokushisa okuphezulu. Hlala kude nomthombo womlilo, umthombo wokushisa nendawo yokushisa ephezulu ngesikhathi sokumisa. Ukuhamba ngomgwaqo kufanele kwenziwe ngokuhambisana nemizila ebekiwe, futhi akufanele kuyeke ezindaweni zokuhlala kanye nezindawo ezinabantu abaningi. Ukuhamba ngezitimela kuvinjelwe ukweqa. Ukuhamba ngobuningi ngemikhumbi yokhuni noma yokwenqatshelwa kwenqatshelwe ngokuphelele. Izimpawu zengozi nezaziso zizothunyelwa ngezindlela zokuhamba ngokuya ngezidingo zokuhamba.

Izinkomba zomzimba nangamakhemikhali (%).

Qaphela: Imikhiqizo ingakhiqizwa futhi ifakwe ngokusho kwemininingwane yabasebenzisi.
