I-Cerium oxide yinto engaphiliyo enefomula yekhemikhali i-CeO2, umgubo otyheli okanye omdaka okhanyayo. Ubuninzi bayo yi-7.13g/cm3, indawo yokunyibilika yi-2397℃, ayinyibiliki emanzini nakwi-alkali, inyibilika kancinci kwi-asidi. Kwi-2000℃ kunye ne-15MPa, i-cerium oxide ingancitshiswa nge-hydrogen ukuze kufunyanwe i-cerium trioxide. Xa ubushushu buphakathi kwe-2000℃ kwaye uxinzelelo luphakathi kwe-5MPa, i-cerium oxide ityheli kancinci ibe bomvu, kwaye ipinki. Ukusebenza kwayo kufuneka kusetyenziswe njengezinto zokupholisha, i-catalyst, i-catalyst carrier (i-arhente yokuncedisa), i-ultraviolet absorber, i-fuel cell electrolyte, i-automobile exhaust absorbent, i-electronic ceramics, njl.
Njengomprosesa ophambili we-cerium oxide kunye nomthengisi ophambili waseTshayina, I-UrbanMines Tech Limited.I-Rare Earth Resources isebenzise ngokupheleleyo iingenelo zeTshayina ze-Rare Earth kunye neengenelo zenkampani zobuchwepheshe bokwahlukanisa nokukhupha iimveliso ukuze ikhonze abathengi behlabathi kangangeminyaka eli-16. Irabha ye-silicone engatshisi ubushushu yeyona nto isetyenziswa kakhulu kwaye yeyona ndawo iphambili ye-cerium oxide kubathengi bethu. Iqela lethu le-R&D liqulunqe eli nqaku ukuphendula imibuzo yobuchwephesha yabathengi.
Iimpawu zerabha ye-silicone engatshisi ubushushu ye-cerium oxide
Irabha ye-silicone engatshisiyo ye-Cerium oxide ngerabha ye-silicone esebenza kakuhle eneempawu ezilandelayo eziphambili:
1. Ukumelana nobushushu obuphezulu: Irabha ye-silicone engatshiyo ye-Cerium oxide inokusebenza ixesha elide kwindawo enobushushu obuphezulu, kwaye ubushushu bayo bokumelana nobushushu bunokufikelela ngaphezulu kwama-300°C.
2. I-Anti-oxidation: Irabha ye-silicone engangeni bushushu ye-Cerium oxide ineempawu ezintle kakhulu zokulwa ne-oxidation kwaye ingasetyenziswa ixesha elide kwiindawo ezinzima ezifana ne-oxidation, i-acidity, kunye ne-alkalinity.
3. Ukumelana nemitha: Irabha ye-silicone engatshisi ubushushu ye-Cerium oxide ingasetyenziswa kwiindawo ezinemitha ephezulu, kwaye ukumelana kwayo nemitha akunakuthelekiswa nezinye iirabha ze-silicone.
4. I-Anti-ultraviolet: Irabha ye-silicone engangeni bushushu ye-Cerium oxide inamandla amahle okulwa ne-ultraviolet kwaye ingasetyenziswa ixesha elide kwiindawo zangaphandle ngaphandle kokuguga.
Amasimi okusetyenziswa kwerabha ye-silicone engatshisi ubushushu ye-cerium oxide
Irabha yesilicone engatshisi ubushushu yeCerium oxide isetyenziswa kakhulu kwiinqwelomoya, kwi-aerospace, kwishishini lenyukliya, kwi-elektroniki, kumbane, kwi-petroleum, kwishishini leekhemikhali, nakwezinye iindawo. Imfuno yayo kwiinkalo zobuchwepheshe obuphezulu ezifana neenqwelomoya, kwi-aerospace, nakwishishini lenyukliya ibaluleke kakhulu. Oku kungenxa yobushushu bayo obuphezulu, ukumelana nemisebe, ukumelana ne-oxidation, kunye nokuxhathisa ukugqwala kweekhemikhali.
Umahluko phakathi kwerabha ye-silicone engatshisi ubushushu ye-cerium oxide kunye nenye irabha ye-silicone
Xa kuthelekiswa nerabha ye-silicone ngokubanzi,i-cerium oxideIrabha ye-silicone engatshiyo ubushushu inokumelana nobushushu obuphezulu, ukumelana ngcono ne-oxidation, ukumelana okunamandla kwemitha, ukumelana ngcono nokugqwala kweekhemikhali, njl. Ke ngoko, kwezinye iindawo ezinzima ezifana nobushushu obuphezulu, imitha ephezulu, i-asidi, kunye ne-alkali, irabha ye-silicone engatshiyo ye-cerium oxide inokudlala indima yayo ngcono.
【ukuququmbela】
Irabha ye-silicone enganyangekiyo kubushushu ye-Cerium oxide ngerabha esemgangathweni ophezulu enokumelana nobushushu obuphezulu, ukumelana ne-oxidation, ukumelana nemitha, ukumelana ne-UV, kunye nezinye iimpawu. Isetyenziswa kakhulu kwiinqwelomoya, kwi-aerospace, kushishino lwenyukliya, kwi-elektroniki, kumbane, kwi-petroleum, kushishino lweekhemikhali, nakwamanye amacandelo. Xa ithelekiswa nezinye iirabha ze-silicone, irabha ye-silicone enganyangekiyo kubushushu ye-cerium oxide ineenzuzo eziphezulu zokusebenza kwaye iyinto ebalulekileyo.
