I-Cerium oxide iyisithako esingaphili esinefomula yamakhemikhali i-CeO2, impuphu ephuzi noma ephuzi ensundu. Ubuningi bayo buyi-7.13g/cm3, iphuzu lokuncibilika lingu-2397℃, ayincibiliki emanzini nase-alkali, incibilika kancane kwi-asidi. Ku-2000℃ kanye ne-15MPa, i-cerium oxide ingancishiswa nge-hydrogen ukuze kutholakale i-cerium trioxide. Uma izinga lokushisa liphakathi kuka-2000℃ futhi ingcindezi iphakathi kuka-5MPa, i-cerium oxide iba phuzi kancane ibe bomvu, futhi ibe pinki. Ukusebenza kwayo kufanele kusetshenziswe njengezinto zokupholisha, i-catalyst, i-catalyst carrier (i-ejenti yokusiza), i-ultraviolet absorber, i-fuel cell electrolyte, i-exhaust absorbent yemoto, i-electronic ceramics, njll.
Njengomprosesa nomhlinzeki we-cerium oxide ochwepheshe ohamba phambili eShayina, I-UrbanMines Tech Limited.I-rare earth resource yaseShayina kanye nezinzuzo zobuchwepheshe bokuhlukanisa nokukhipha zenkampani ukuze ikhonze amakhasimende omhlaba wonke iminyaka eyi-16. Irabha ye-silicone engashisi ukushisa iyindlela eyinhloko yokusetshenziswa kanye nensimu ye-cerium oxide kumakhasimende ethu. Ithimba lethu le-R&D lihlanganise lesi sihloko ukuze liphendule imibuzo yobuchwepheshe yamakhasimende.
Izici zerabha ye-silicone engamelana nokushisa ye-cerium oxide
Irabha ye-silicone engangenisi ukushisa ye-Cerium oxide iyinto yerabha ye-silicone esebenza kahle kakhulu enezici ezilandelayo eziyinhloko:
1. Ukumelana nokushisa okuphezulu: Irabha ye-silicone engamelani nokushisa ye-Cerium oxide ingasebenza isikhathi eside endaweni enokushisa okuphezulu, futhi izinga lokushisa layo lokumelana nokushisa lingafinyelela ngaphezu kuka-300°C.
2. Ukulwa nokushiswa kwe-oxidation: Irabha ye-silicone engangeni ukushisa ye-Cerium oxide inezakhiwo ezinhle kakhulu zokulwa nokushiswa kwe-oxidation futhi ingasetshenziswa isikhathi eside ezindaweni ezinzima njenge-oxidation, i-acidity, kanye ne-alkalinity.
3. Ukumelana nemisebe: Irabha ye-silicone engamelani nokushisa ye-Cerium oxide ingasetshenziswa ezindaweni ezinemisebe eminingi, futhi ukumelana kwayo nemisebe akunakuqhathaniswa nezinye irabha ze-silicone.
4. I-Anti-ultraviolet: Irabha ye-silicone engangenisi ukushisa ye-Cerium oxide inokusebenza okuhle kokulwa ne-ultraviolet futhi ingasetshenziswa isikhathi eside ezindaweni zangaphandle ngaphandle kokuguga.
Amasimu okusetshenziswa kwerabha ye-silicone engangenisi ukushisa ye-cerium oxide
Irabha ye-silicone engashisi i-Cerium oxide isetshenziswa kabanzi ezindizeni, ezindizayo, embonini yenuzi, kuma-elekthronikhi, kugesi, kuphethiloli, embonini yamakhemikhali, nakweminye imikhakha. Isidingo sayo emikhakheni yobuchwepheshe obuphezulu njengezindiza, izindiza, kanye nemboni yenuzi sivelele kakhulu. Lokhu kungenxa yokushisa kwayo okuphezulu, ukumelana nemisebe, ukumelana nokugqwala kwamakhemikhali.
Umehluko phakathi kwerabha ye-silicone engamelani nokushisa ye-cerium oxide kanye nenye irabha ye-silicone
Uma kuqhathaniswa nerabha ye-silicone ejwayelekile,i-cerium oxideIrabha ye-silicone engamelani nokushisa inokumelana nokushisa okuphezulu, ukumelana okungcono kwe-oxidation, ukumelana okukhulu kwemisebe, ukumelana okungcono kokugqwala kwamakhemikhali, njll. Ngakho-ke, kwezinye izindawo ezinzima njengokushisa okuphezulu, imisebe ephezulu, i-asidi, kanye ne-alkali, irabha ye-silicone engamelani nokushisa ye-cerium oxide ingadlala indima yayo kangcono.
【Ekuphetheni】
Irabha ye-silicone engamelani nokushisa ye-Cerium oxide iyinto yerabha esebenza kahle kakhulu enokumelana nokushisa okuphezulu, ukumelana nokushiswa kwe-oxidation, ukumelana nemisebe, ukumelana ne-UV, nezinye izici. Isetshenziswa kabanzi ezindizeni, ezindizayo, embonini yenuzi, kuma-elekthronikhi, kugesi, kuphethiloli, embonini yamakhemikhali, nakwamanye amasimu. Uma iqhathaniswa namanye amarabha e-silicone, irabha ye-silicone engamelani nokushisa ye-cerium oxide inezinzuzo zokusebenza okuphezulu futhi iyinto ebalulekile.
