Inkcazo kunye neempawu

Inkcazo: I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluI-Lanthanum Sulfate Hydrare.

Ezona mpawu:

Ubunyulu obuphezulu:I-Lanthanum Sulfate Hydrare ayinazo izinto ezingcolisayo ezivela kwizinto ezinqabileyo zomhlaba (ezifana nesinyithi, ikhalsiyam, isodiyam), kwaye umxholo wokungcola uphantsi.

Ukunyibilika Okulungileyo:I-Lanthanum Sulfate Hydrare inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki: Ulawulo olungqongqo lwebhetshi ekuvelisweni kweI-Lanthanum Sulfate Hydrare

iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

I-catalyst yeshishini leekhemikhali: I-hydrated lanthanum sulfate yinxalenye ebalulekileyo ye-catalytic cracking (FCC) catalyst esetyenziswa kwishishini le-petrochemical. Ingaphucula ngempumelelo ukusebenza kakuhle kokuguqula i-oyile enzima ekrwada ibe yi-high-octane gasoline kunye ne-diesel. Ingasebenza njenge-catalyst okanye i-catalyst precursor ye-organic synthesis reactions ezithile.

Izixhobo zokugcina ubushushu beekhemikhali: Ngenxa yeempawu zayo zokuphendula ngokuphelelwa ngamanzi emzimbeni/ukufuma, i-lanthanum sulfate hydrate sisixhobo sokugcina ubushushu beekhemikhali esithembisayo kakhulu. Ingafumana iimpendulo eziguqukayo ngaphakathi komgangatho wobushushu ophantsi (malunga ne-100).°C ukuya kwi-250°C), kwaye isetyenziselwa ukubuyisa nokugcina ubushushu benkunkuma yemizi-mveliso. Inobuninzi bokugcina amandla kunye nokuqina komjikelo ogqwesileyo.

Isithambisi sePhosphorus echibini: Ngenxa yeempawu zayo zeekhemikhali, i-lanthanum sulfate inokususa i-phosphate ngokufanelekileyo kwimizimba yamanzi ngokuna kwemvula, nto leyo eluncedo ekusombululeni ingxaki yokususwa kwe-eutrophication emzimbeni wamanzi.

Izinto ezidityanisiweyo zekhemikhali: Njengomthombo obalulekileyo we-lanthanum, i-lanthanum sulfate emanzi yimbangela ephambili yokwenziwa kwezinye iikhompawundi ze-lanthanum, kwaye isetyenziselwa ukulungiselela izinto ezahlukeneyo ezisebenzayo ezifana ne-lanthanum oxide kunye ne-lanthanum-based phosphors. Ikwasetyenziswa njenge-reagent kuphando lwesayensi olufana nohlalutyo lwe-spectroscopy kunye nokumisela ubunzima be-athomu yezinto.
