Kushandiswa kweCerium oxide

Cerium Oxide, inonziwo Ceria, inoshandiswa zvakanyanya mugirazi, ceramics uye catalyst kugadzira.Muindasitiri yegirazi, inoonekwa seyakanyanya kushanda girazi yekupolisha mumiriri weiyo chaiyo optical polishing.Inoshandiswawo kuita decolorize girazi nekuchengeta iron iri muferrous state.Kugona kwegirazi reCerium-doped kuvharisa mwenje we ultra violet kunoshandiswa mukugadzira girazi rekurapa uye mahwindo emuchadenga.Inoshandiswawo kudzivirira mapolymer kubva mukusviba muchiedza chezuva uye kudzvanyirira kushanduka kwegirazi reterevhizheni.Inoshandiswa kune optical components kuti uvandudze kushanda.Kuchena kwepamusoro Ceria inoshandiswawo muphosphors uye dopant kune crystal.

Cerium oxide, inozivikanwawo seceria, isanganiswa inoumbwa nezvinhu cerium uye oxygen ine kemikari formula CeO2.Ihwo hupfu hwakajeka hweyero kana huchena, hunogadzikana pasi pemamiriro ezvinhu.Cerium oxide ine zvakasiyana-siyana zvekushandisa, kusanganisira:

1. Catalyst: Cerium oxide inoshandiswa sechinhu chinokonzeresa mune dzakawanda maindasitiri maitiro, senge muindasitiri yemotokari kune catalytic converters kuderedza kuburitswa uye kugadzirwa kwemafuta ekugadzira.

2. Polishing agent: Cerium oxide inoshandiswa sechinhu chinopenya chegirazi nezvimwe zvinhu.Inoshanda zvakanyanya pakutsvedzerera nzvimbo dzakashata uye kubvisa makwara.

3. Mafuta ekuwedzera: Inogona kushandiswa sechinhu chinowedzera mafuta kukurudzira kuchena uye kunyatsoita kupisa kwemafuta.

4. Girazi indasitiri: Cerium oxide inoshandiswa muindasitiri yegirazi kugadzira girazi remhando yepamusoro nekuti inogona kuwedzera refractive index uye kuwedzera kusimba kwegirazi.

5. Solar cell production: Cerium oxide inoshandiswa sechinhu chinoputira pakugadzirwa kwemasero ezuva.Pakazere, cerium oxide ine akawanda maapplication uye iyo yakakosha komisheni mumaindasitiri akasiyana nekuda kweiyo yakasarudzika zvivakwa.

6.inoshandiswa segirazi decolorizing agent uye girazi rinopisa poda.Inoshandiswawo seyakagadzirwa mukugadzira simbi cerium.Kuchena kwepamusoro Cerium dioxide yakakosha mukushandiswa kwezvinhu zvisingawanzo pasi pefluorescent

Packaging yeCerium Oxide: 25kg / bhegi kana 50 kg / bhegi Muine bhegi, rine 1000Kg net imwe neimwe, PVC bhegi mukati, rakarukwa bhegi kunze

KugadzirirayeCerium oxide:

Carbonate precipitation method ine solution yecerium chloride sechinhu chekutanga chakaparadzaniswa nekucherwa neaqueous ammonia Ph iri 2, pamwe neprecipitated cerium carbonate uye ammonium bicarbonate, kupisa kupisa, kugeza, kupatsanura, uyezve calcined pa900 ~ 1000 ℃ cerium oxide.

Safety ofCerium oxide:
Isiri-chepfu, isingaravike, isingatsamwire, yakachengeteka, yakavimbika, yakagadzikana kuita, ine mvura uye organic kemikari maitiro haaitike, ndiyo yakanaka nyowani kana UV sunscreen agents.
Acute toxicity: Oral - Rat LD50:> 5000 mg / kg;intraperitoneal - mbeva LD50: 465 MG / kg.
Inopisa ine njodzi maitiro: isingabatike.
Storage features: yakaderera tembiricha yakaoma uye ventilated warehouse.
Kudzima Media: Mvura.
