Hs Code Rau Dub Silicon Carbide
Dub silicon carbideyog ib tug nrov abrasive khoom siv nyob rau hauv ntau yam kev siv. Nws muaj nyob rau hauv cov duab sib txawv thiab ntau thiab tsawg rau kev sib tsoo, txiav, polishing, thiab kev ua haujlwm sandblasting. Raws li cov xim dub silicon carbide yog cov khoom siv ntau yam nrog qhov tshwj xeeb hardness thiab durability, nws pom daim ntawv thov hauv ntau hom kev lag luam, suav nrog tsheb, aerospace, kev tsim kho, thiab hluav taws xob.
Lub Harmonized System (HS) Code rau dub silicon carbide yog 2849.20. Nws yog categorized raws li cov khoom ntxhia ntu ntawm HS Code. HS Code yog ib qho kev lees paub thoob ntiaj teb rau kev faib cov khoom thiab cov khoom muag, thiab nws yog siv rau kev lis kev cai clearance thiab tariff lub hom phiaj. Dub silicon carbide yog tsim los ntawm cov txheej txheem hu ua smelting, uas muaj cua sov silica thiab carbon ntawm qhov kub thiab txias. Cov khoom tsim tau yog cov khoom siv tawv thiab nkig nrog cov qauv crystalline. Nws muaj Mohs hardness ntawm 9.5, ua rau nws yog ib qho nyuaj tshaj plaws rau txiv neej.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov xim dub silicon carbide yog nws lub peev xwm los tswj nws qhov ntse thiab tawv txawm nyob rau qhov kub thiab txias. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev txiav thiab sib tsoo daim ntaub ntawv uas muaj cov hlau tawv thiab alloys. Nws lub zog tshwj xeeb thiab kev ua haujlwm ntev kuj ua rau nws tsim nyog siv los ua cov abrasive hauv kev siv sandblasting.
Vim nws cov khoom tshwj xeeb,dub silicon carbideyog dav siv nyob rau hauv kev tsim ntawm kev sib tsoo log, txiav cov cuab yeej, polishing agents, thiab cov ntaub ntawv refractory. Nws kuj tseem siv rau hauv kev tsim cov khoom siv semiconductor, xws li diodes thiab transistors, thiab ua cov khoom siv txheej hauv cov hnub ci vaj huam sib luag. Kev siv cov dub silicon carbide xav tias yuav loj hlob ntau nyob rau xyoo tom ntej, uas tau tsav los ntawm kev xav tau ntau ntxiv rau kev ua haujlwm siab abrasives thiab cov khoom siv siab heev. Raws li qhov tshwm sim, lub ntiaj teb ua lag luam rau dub silicon carbide tau kwv yees kom ncav cuag $ 4.6 billion los ntawm 2025, raws li tsab ntawv ceeb toom los ntawm Grand View Research.
Hauv kev xaus, dub silicon carbide yog cov khoom siv ntau yam thiab ruaj khov, dav siv hauv ntau daim ntawv thov kev lag luam. Nws cov khoom tshwj xeeb ua rau nws cov khoom siv zoo heev rau kev txiav, sib tsoo, polishing, thiab kev ua haujlwm sandblasting, thiab lwm yam. Nrog rau qhov kev thov loj zuj zus rau kev ua haujlwm siab abrasives thiab cov khoom siv siab heev, kev siv cov dub silicon carbide yuav tsum tau nce sai hauv xyoo tom ntej.
