Daim ntawv thov
Cerium fluoride tef3, yog cov khoom siv tseem ceeb rau cov hmoov polishing, tshwj xeeb iav, metallurgical daim ntaub ntawv. Hauv kev lag luam iav, nws tau suav tias yog qhov ua tau zoo tshaj plaws iav polishing tus neeg sawv cev rau precision kho qhov muag polishing. Nws tseem siv los daws teeb lub khob los ntawm kev khaws cov hlau hauv nws lub xeev ferrous. Hauv kev tsim cov hlau, nws yog siv los tshem cov pa oxygen dawb thiab leej faj los ntawm kev tsim cov kab khiav tawm oxysulfide thiab los ntawm khi cov kab tsis muaj kev cia siab, xws li cov hmoov txhuas thiab tshuaj pleev ib ce.
