Inkcazo kunye neempawu

Inkcazo: I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluUbungakanani obukhulu beCerium Carbonate.

Ezona mpawu:

Ubunyulu obuphezulu:Ubungakanani obukhulu beCerium Carbonate ayinazo izinto ezingcolisayo ezivela kwizinto ezinqabileyo zomhlaba (ezifana nesinyithi, ikhalsiyam, isodiyam), kwaye umxholo wokungcola uphantsi.

Ukunyibilika Okulungileyo:Ubungakanani obukhulu beCerium Carbonate inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki: Ulawulo olungqongqo lwebhetshi ekuvelisweni kweUbungakanani obukhulu beCerium Carbonate iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

I-catalyst yeshishini leekhemikhali: I-cerium carbonate enkulu yinto ebalulekileyo yokulungiselela ii-catalysts ezintathu-way zokukhupha umoya zeemoto. Ngokusebenzisa i-calcination yobushushu obuphezulu, ingaguqulwa ibe yi-cerium oxide enomthamo ophezulu wokugcina ioksijini, ngaloo ndlela ikhuthaza ngempumelelo ii-catalytic cleansing reactions ze-carbon monoxide, ii-hydrocarbons, kunye ne-nitrogen oxides.

I-Agent yokususa i-Phosphorus esebenzayo: Ngokusekelwe kubudlelwane obuphezulu phakathi kwee-ion ze-cerium kunye nee-ion ze-phosphate, i-cerium carbonate enkulu ingasetyenziswa njenge-arhente yokususa i-phosphorus yonyango lwamanzi kunye nokubuyiselwa kwemizimba yamanzi e-eutrophic. Ubungakanani bayo obukhulu bee-particle buvumela ukusebenza ngcono kwe-sedimentation kwizicelo ezisebenzayo, okwenza kube lula ukwahlukana kunye nokubuyiselwa, kwaye kuncitshiswe ngempumelelo ukuxinana kwe-phosphorus iyonke kwi-dfluent ukuya kwinqanaba eliphantsi kakhulu (umz., ukusuka kwi-0.55 mg-P/L ukuya kwi-≤0.03 mg-P/L).

Iiceramics kunye nezinto zokuPolisha: I-cerium carbonate enkulu yimpahla ebalulekileyo yokwenza iiceramics ezikhethekileyo (ezifana neeceramics ze-elektroniki) kunye neepowders zokupolisha ezisebenzayo. Ubungakanani bayo obukhulu beesuntswana bunceda ekufezekiseni umphezulu wokupolisha ogudileyo, obaluleke kakhulu kwi-chemical mechanical polishing (CMP) yeglasi ye-optical kunye nee-semiconductor wafers. Ingasetyenziswa njengesongezelelo kwi-alloys ezinzima ukuphucula ukusebenza kwezixhobo.

Izinto ezidityanisiweyo zekhemikhali: Njengesandulela esibalulekileyo seekhompawundi ze-cerium, i-cerium carbonate enkulu isetyenziselwa ukuvelisa iityuwa ezahlukeneyo ze-cerium (ezifana ne-cerium nitrate, i-cerium chloride, njl.njl.) kwaye ekugqibeleni ukulungiselela i-cerium oxide ecocekileyo kakhulu. Ngokulawula ngokungqongqo iimeko zemvula (ezifana noxinzelelo lwesisombululo se-rare earth, ubushushu bokusabela, kunye nexesha lokwaluphala), ubungakanani be-particle yemveliso bunokulungiswa ngokulawulwayo (ubungakanani be-particle ephakathi i-D50 bunokufikelela malunga ne-150μm), ukuhlangabezana neemfuno ezithile zezicelo ezahlukeneyo ezisezantsi zobungakanani bamasuntswana ezinto ezikrwada.
