Uses:.Lanthanum carbonateis an inorganic compound inoumbwa nelanthanum element uye carbonate ion. Iyo inoratidzirwa nekugadzikana kwakasimba, kuderera kwekugadzirisa uye kushanda kwemakemikari zvinhu. Muindasitiri, lanthanum carbonate inogona kushandiswa zvakanyanya mumakeramiki, zvemagetsi, mushonga uye mamwe minda. Pakati pavo, lanthanum carbonate inoita basa rinokosha muindasitiri yekeramics, inogona kushandiswa se pigment, glaze, girazi additives, nezvimwewo; mumunda wemagetsi, lanthanum carbonate inogona kugadzirirwa nepamusoro yemagetsi conductivity, kutsika-kupisa sintering yezvinhu zvakasimba, zvakakodzera kugadzirwa kwepamusoro-simba-density capacitors, inoshandiswa mukugadzira ternary catalysts, cemented carbide additives; mumunda wemishonga,lanthanum carbonatechinhu chinowedzera kumishonga, uye chinogona kushandiswa kurapa Mumunda wemishonga,lanthanum carbonatechinhu chakajairika chemishonga chinowedzera, chinogona kushandiswa pakurapa hypercalcemia, hemolytic uremic syndrome uye zvimwe zvirwere, uye inokodzera kurapwa kwe hyperphosphatemia mumagumo erenal chirwere varwere. Neshoko rimwe chete,lanthanum carbonateine mabasa akawanda uye inoshandiswa zvakanyanya muindasitiri yemakemikari yemazuva ano, sainzi yezvinhu, mushonga uye mamwe minda.
Packing: 25, 50/kg, 1000kg/tani mubhegi rakarukwa, 25, 50kg/barrel mukadhibhodhi dhiramu.
Kugadzira sei:
Lanthanum carbonatendicho chinhu chikuru chekugadzirwa kwelanthanum oxide [1-4]. Nekuwedzera kuri kukurumidza kwemamiriro ekuchengetedzwa kwezvakatipoteredza, ammonium bicarbonate, senzvimbo yechinyakare yekugadzirira lanthanum carbonate, yakashandiswa zvakanyanya mukugadzirwa kwemaindasitiri [5-7], kunyangwe iine zvakanakira mutengo wakaderera wekugadzira uye kuderera kwetsvina. ye carbonate yakawanikwa. Nekudaro, nekuda kweiyo eutrophication yeNH + 4 mumvura yetsvina yeindasitiri, iyo ine simba rakakura pane zvakatipoteredza, huwandu hweammonium salt inoshandiswa muindasitiri iyi yakaiswa pamberi zvakanyanya kuomarara zvinodiwa. Seimwe yeakanyanya precipitants, sodium carbonate, ichienzaniswa neammonium bicarbonate, mukugadzirira kwelanthanum carbonate in nzira yemvura yakasvibiswa yeindasitiri isina ammonia, tsvina yenitrogen, iri nyore kubata nayo; kana ichienzaniswa nesodium bicarbonate, kugadzirisa kune zvakatipoteredza yakasimba [8 ~ 11].Lanthanum carbonateine sodium carbonate semvura inonaya pakugadzirira kwepasi-sodium isingawanzoitiki pasi carbonate haiwanzo kutaurwa mumabhuku, iyo inotora yakachipa, kushanda kuri nyore kweiyo yakanaka feeding precipitation method, uye low-sodium.lanthanum carbonateinogadzirirwa nekudzora nhevedzano yemamiriro ekuita.
Precautions pakufambisa kwelanthanum carbonate: Mota dzekufambisa dzinofanirwa kunge dzakashongedzerwa nemhando dzakakodzera uye huwandu hwemidziyo yekudzimisa moto uye inodonha yemidziyo yekukurumidzira yekurapa. Izvo zvinorambidzwa zvachose kusanganisa uye kutakura neoxidizers uye makemikari anodyika. Iyo pombi yekupopota yemotokari inotakura zvinhu inoda kuve yakashongedzerwa nemurazvo wemoto. Kana marori anotakura matangi achishandiswa kutakura, cheni dzepasi dzinofanirwa kuiswa. Kuti uderedze iyo static magetsi anogadzirwa ne vibration, zvinokwanisika kuisa gomba dividers mutangi. Izvo zvinorambidzwa kurodha kana kuburitsa michina michina uye maturusi anowanzo kupfava. Muzhizha mangwanani uye manheru kutakura kwakanaka, mukufambisa kwekutakura, kudzivirira zuva nemvura uye kupisa kwakanyanya. Gara kure nenzvimbo yemoto, sosi yekupisa uye nzvimbo yekupisa yakanyanya panguva yekumira. Kufambiswa kwemigwagwa kunofanirwa kuitwa nenzira dzakatarwa, uye hakufanirwe kumira munzvimbo dzinogara vanhu uye munzvimbo dzine vanhu vakawanda. Kufambiswa kwenjanji kunorambidzwa kubva pakutsvedza. Kutakurwa kwehuwandu nengarava dzemapuranga kana simende kunorambidzwa zvachose. Zviratidzo zvengozi uye zviziviso zvichaiswa munzira dzekufambisa zvinoenderana nezvinodiwa zvekufambisa.
