Koj puas tau xav paub dab tsi cov cuab yeej ua khawv koob no ua rau qhov chaw du thiab ci? Lawv yog cov ntaub emery, ib qho khoom siv sib tsoo hauv peb lub neej txhua hnub. Niaj hnub no, peb yuav delve rau hauv cov teeb meem kev tshaj lij ntawm emery ntaub.
Dab tsi yog qhovdaim ntaub xuab zeb?
xuab zeb daim ntaub yog ib yam khoom uas muaj li ntawm daim ntaub thiab abrasive hais, uas yog feem ntau siv rau kev sib tsoo ntawm ntau yam khoom. Nws cov khoom abrasive yog embedded rau hauv cov ntaub, thiab los ntawm kev sib txhuam nrog cov khoom nto, qhov saum npoo ntawm cov khoom raug tshem tawm ntawm qhov tsis xws luag thiab irregularities, yog li ntawd lub nto ntawm cov khoom yuav du.
Dab tsi yog cov ntawv thov tseem ceeb ntawm cov ntaub xuab zeb?
Kev siv lub ntsiab ntawm emery ntaub yog polish thiab polish ntau yam ntaub ntawv, xws li hlau, ntoo, yas thiab lwm yam. Emery daim ntaub plays lub luag haujlwm tseem ceeb hauv kev tsim khoom, kev kho tsheb, kev tsim rooj tog, kos duab tsim thiab lwm yam haujlwm.
Cov khoom siv thiab qhov loj me ntawm cov ntaub xuab zeb cuam tshuam li cas rau nws txoj kev sib tsoo?
Ua ntej ntawm tag nrho cov, cov khoom ntawm emery daim ntaub txiav txim siab nws hardness, hnav tsis kam thiab kev pab cuam lub neej. Cov ntaub ntawv emery feem ntau yog alumina, silicon carbide, ntuj abrasive thiab lwm yam. High hardness ntawm alumina emery daim ntaub, haum rau kev sib tsoo cov ntaub ntawv nyuaj, xws li hlau; Silicon carbide emery daim ntaub muaj kev hnav zoo dua, haum rau polishing softer cov ntaub ntawv, xws li ntoo, yas thiab lwm yam. Natural abrasive daim ntaub muaj kev ua haujlwm zoo dua, haum rau kev sib tsoo zoo.
Qhov thib ob, qhov loj me me ntawm daim ntaub emery kuj yog qhov tseem ceeb cuam tshuam rau kev sib tsoo. Qhov loj me yog hais txog qhov loj ntawm cov khoom hauv av ntawm daim ntaub emery, feem ntau qhia hauv mesh (tus naj npawb ntawm cov khoom ib nti). Qhov me me particle loj, qhov finer particle, lub smoother lub polished nto. Hloov pauv, qhov loj dua qhov loj me me, qhov coarser lub particle, thiab coarser lub polished nto. Yog li ntawd, thaum xaiv daim ntaub emery, qhov tsim nyog particle loj yuav tsum tau xaiv raws li qhov chaw ntawm cov khoom yuav tsum polished thiab yuav tsum tau sib tsoo nyhuv.
Hauv kev siv tswv yim, cov khoom siv thiab qhov loj me ntawm daim ntaub emery yuav tsum tau txiav txim siab ua tiav. Piv txwv li, rau qhov tsis xws luag ntawm cov hlau nto, alumina emery daim ntaub nrog siab hardness thiab coarse particle loj tuaj yeem xaiv rau kev sib tsoo ua ntej; Rau cov hlau nto uas xav tau polishing zoo, lub ntuj abrasive emery daim ntaub nrog zoo particle loj thiab zoo abrasive kev ua tau zoo tuaj yeem raug xaiv rau kev kho mob tom ntej.
Tsis tas li ntawd, kev siv cov ntaub emery thiab kev txawj ntse tseem yuav cuam tshuam rau nws txoj kev sib tsoo. Piv txwv li, thaum siv daim ntaub emery, nws yog ib qho tsim nyog yuav tsum tswj kom muaj lub siab tsim nyog thiab lub kaum sab xis kom tsis txhob sib tsoo ntau dhau los yog khawb. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau lub sijhawm hloov ntawm cov ntaub emery hnyav hnyav kom tswj tau qhov kev ruaj ntseg ntawm kev sib tsoo.
Nyob rau hauv luv luv, cov khoom thiab particle loj ntawm lubdaim ntaub xuab zebyog cov yam tseem ceeb uas cuam tshuam rau nws txoj kev sib tsoo. Hauv kev xaiv thiab siv cov ntaub emery, nws yog ib qho tsim nyog yuav tsum xav txog cov khoom siv, qhov loj me, siv txoj kev thiab lwm yam raws li qhov xwm txheej tiag tiag kom ua tiav qhov kev sib tsoo zoo tshaj plaws.
