Cov txheej txheem ntau lawm ntawmdub silicon carbidefeem ntau suav nrog cov kauj ruam hauv qab no:
1.Raw Material Preparation: Cov ntaub ntawv tseem ceeb rau cov dub silicon carbide ntau lawm yog cov zoo silica xuab zeb thiab roj av coke.Cov ntaub ntawv no tau ua tib zoo xaiv thiab npaj rau kev ua haujlwm ntxiv.
2.Mixing: Cov silica xuab zeb thiab roj av coke yog tov rau hauv qhov xav tau proportions kom ua tiav cov tshuaj muaj pes tsawg leeg xav tau.Lwm cov additives kuj tseem yuav ntxiv rau theem no los txhim kho cov khoom tshwj xeeb ntawm cov khoom kawg.
3.Crushing thiab Sib Tsoo: Cov khoom sib xyaw ua ke yog crushed thiab hauv av rau hauv cov hmoov zoo.Cov txheej txheem no yuav pab kom ua tiav ib qho kev faib khoom me me, uas yog qhov tseem ceeb rau kev tau txais cov khoom zoo ib yam.
4.Carbonization: Cov hmoov sib tov yog tom qab ntawd muab tso rau hauv qhov cub hluav taws xob lossis lub qhov cub graphite.Qhov kub tau nce mus txog 2000 txog 2500 degrees Celsius hauv qhov chaw tsis muaj zog.Ntawm qhov kub siab no, carbonization tshwm sim, hloov cov sib tov rau hauv cov khoom hnyav.
5.Crushing thiab Sieving: Lub carbonized loj yog txias thiab ces crushed mus rau hauv me me pieces.Cov khoom no ces sieved kom tau qhov xav tau particle loj tis.Cov khoom siv sieved yog hu ua ntsuab silicon carbide.
6.Grinding thiab Classification: Cov xim ntsuab silicon carbide tau ua tiav ntxiv los ntawm kev sib tsoo thiab kev faib tawm.Kev sib tsoo yuav txo qhov me me ntawm cov khoom mus rau qhov xav tau, thaum kev faib cais cov khoom raws li qhov loj me.
Purification thiab Acid Washing: Txhawm rau tshem tawm cov impurities thiab cov pa roj carbon monoxide, cov silicon carbide tau muab faib ua cov txheej txheem purification.Acid ntxuav feem ntau yog siv los tshem tawm cov hlau tsis huv thiab lwm yam kab mob.
7.Drying thiab Ntim: Cov purified silicon carbide yog qhuav kom tshem tawm cov dej noo.Tom qab ziab, nws yog npaj rau ntim.Cov khoom kawg yog feem ntau ntim rau hauv hnab lossis ntim rau kev faib khoom thiab muag.
