Lub ntim ntim ntawm cov khoom siv abrasives hauv thawj ib nrab xyoo 2022 yog US $ 110 lab, nqis 4.5% xyoo-rau- xyoo. Ntawm lawv, cov ntshuam xim av corundum poob 81.43% xyoo- ntawm- xyoo, thiab tus nqi ntshuam tau nce 14.02% xyoo-rau- xyoo; ntshuam ntim ntawm lwm yam khoom dag corundum (feem ntau yog dawb corundum) poob 27.82% xyoo-rau- xyoo, thiab tus nqi ntshuam poob 23.23% xyoo-rau- xyoo; ntshuam ntim ntawm silicon carbide tau nce 420.51% xyoo-rau- xyoo, thiab tus nqi ntshuam nce 52.87% xyoo-rau- xyoo; ntshuam ntim ntawm abrasives poob 3.55% xyoo-rau- xyoo, thiab tus nqi ntshuam poob 5.33%.
Sib piv cov lus 1 thiab Table 2, peb tuaj yeem pom tau tias Tuam Tshoj, raws li cov neeg tsim khoom loj ntawm abrasives, kev xa tawm yog 13 npaug ntau dua li kev xa tawm, uas yog qhov tseem ceeb ntawm kev lag luam, vim tias cov ntim ntim me me, yog li qhov kev hloov pauv ntawm ntau yam khoom kuj tshwm sim ntau dua. Nws yog ib qho tseem ceeb uas piv nrog tus nqi nruab nrab ntawm kev xa tawm thiab kev xa tawm, tus nqi nruab nrab ntawm kev xa tawm ntawm txhua yam khoom yog siab dua li kev xa tawm, uas tseem qhia tau tias feem ntau ntawm cov khoom tuaj txawv teb chaws yog siab- cov khoom qib siab, ntxiv kev xav tias Tuam Tshoj txoj kev lag luam abrasives tseem nyob rau hauv lub xeev loj tab sis tsis muaj zog, thiab qee qhov siab - cov khoom lag luam qib siab ntawm kev xa khoom.
Nyob rau hauv cov nqe lus ntawm kev faib ua feem ntawm ntshuam ntawm plaub yam khoom tseem ceeb, lub ntsiab ntshuam destinations rau tag nrho cov hom ntawm cov khoom yog tsim kev lag luam xws li cov teb chaws Europe, lub tebchaws United States, Nyiv thiab South Kauslim, tshwj tsis yog cov silicon carbide, uas yog ib qho yooj yim raws li cov qeb duas ntawm ntshuam cheeb tsam nyob rau hauv 2021, thiab kuj tau lees paub los ntawm sab uas imports 1} cov khoom qib siab {{ Kev rov pib dua ntawm smelting ntawm dub silicon carbide hauv cheeb tsam ntawm North Kauslim tau ua rau muaj kev nce ntxiv hauv kev xa khoom ntawm silicon carbide.
Raws li kev kwv yees los ntawm ntau lub tog neeg, cov cim qhia txog kev poob qis hauv Tebchaws Europe thiab Tebchaws Meskas yuav pom meej dua nyob rau ib nrab xyoo 2022, thiab tseem muaj qhov tsis paub tseeb txog seb qhov kev xa tawm rov qab tuaj rau lub Rau Hli yuav muaj kev txhawb nqa. Ntau tshaj 30% ntawm kev lag luam cov khoom siv rau kev xa tawm, yog li peb cia siab tias cov tuam txhab tuaj yeem npaj ua ntej thiab ua raws li kev ruaj ntseg yog qhov tseem ceeb los tswj kev noj qab haus huv.
