Ceramic balls muab cov yam ntxwv ua tau zoo rau cov ntawv thov raug rau cov tshuaj lom neeg lossis cov xwm txheej uas muaj qhov kub thiab txias heev. Hauv cov ntawv thov xws li cov twj siv tshuaj thiab cov hlua tho, qhov twg cov khoom siv ib txwm ua tsis tiav, cov pob zeb ceramic muab lub neej ntev, hnav tsis kam, thiab tej zaum kev ua tau zoo.
Alumina Ceramic Pob
Vim nws cov kev tiv thaiv zoo tshaj plaws thiab cov yam ntxwv ntawm kev ua haujlwm siab, alumina oxide (AL2O3) yog qhov kev xaiv nrov rau cov khoom siv ceramic. Cov cuab yeej ua haujlwm siv cov pob alumina oxide los txhim kho cov kabmob kev ua haujlwm. Piv nrog rau lawv cov steel counterparts, alumina oxide npas yog hnyav dua, nruj, smoother, tougher, corrosion-resistant, yuav tsum tau lubrication tsawg, thiab muaj ib tug qis thermal expansion, cia cov bearings ua hauj lwm ntawm ntau dua speeds thiab ua hauj lwm kub nrog tsawg torque. Alumina ceramic npas tau dav siv hauv roj av, tshuaj, chiv, roj av, thiab kev tiv thaiv ib puag ncig kev lag luam raws li cov catalysts hauv reactor npog cov khoom txhawb nqa thiab ntauwd ntim.
Zirconia Ceramic Pob
Nws yog ib yam khoom muaj zog uas ua haujlwm tau zoo ntawm qhov kub siab txog 1000 ° F (538 ° C) thiab ua haujlwm zoo hauv cov xwm txheej xws li cov hlau molten, cov kuab tshuaj organic, caustics, thiab feem ntau ntawm cov kua qaub. Nws yog feem ntau siv los ua lub pob valve rau kev tswj dej ntws vim tias nws zoo heev rau kev puas tsuaj thiab corrosion.
Silicon Nitride Ceramic Balls
Ceramic balls ua los ntawm silicon nitride (Si3N4) feem ntau siv rau hauv cov kabmob vim tias lawv muaj zog tiv thaiv tshav kub thiab tsis muaj kev sib txhuam. Lawv kuj tau nquag siv hauv kev lag luam suav nrog cov cuab yeej ua haujlwm hlau, roj turbines, automotive engine qhov chaw, tag nrho cov kabmob ceramic, tub rog thiab tiv thaiv, thiab aerospace.
Nyob rau hauv daim ntawv thov uas yuav tsum tau super high-speed tig, tag nrho cov ceramic thiab hybrid ceramic bearings siv silicon nitride npas. Silicon nitride muaj qhov ntom ntom uas tsawg dua li ib nrab ntawm cov hlau, txo cov quab yuam centrifugal thaum lub sijhawm sib hloov, uas tso cai rau kev ua haujlwm siab dua.
Lawv yog cov khoom siv hluav taws xob tsis zoo thiab tsim nyog rau kev siv xws li hluav taws xob lub cev muaj zog ncej bearings rau AC thiab DC motors thiab generators. Silicon nitride pob bearings tau sai dhau los ua tus qauv kev lag luam hauv kev tsim cov tshuab hluav taws xob rau hluav taws xob thiab tsheb tsis muaj tsheb.
Silicon nitride qhov tsis zoo ntawm cov hlau nplaum ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv hauv cov ntawv thov uas yuav tsum tau tiv thaiv cov hlau nplaum. Lub teb sib nqus lossis lub zog spinning tej zaum yuav cuam tshuam yog tias cov pob hlau siv rau hauv qee yam kev siv. Nyob qhov twg muaj cov teb sib nqus, silicon nitride pob bearings yog qhov zoo tshaj plaws rau kev siv hauv semiconductor manufacturing khoom thiab cov khoom siv kho mob.
