Luv luv qhia cov khoom siv abrasive qis thiab sab hauv qhov sib tsoo pas nrig
Nov 24, 2021
Abrasives yog ib qho khoom siv hauv peb lub neej thiab ntau lawm. Nyob rau hauv lub neej, tib neeg siv pob zeb los yog steel mills rau grind riam; Sib tsoo saw hniav; Sandpaper rau phab ntsa sib tsoo; Iav puab qhov sib tsoo pas nrig rau kev sib tsoo iav; Drill ntsis rau reaming; Sib tsoo log rau kev sib tsoo ib leeg; Ib rab riam ntse ntse riam chav ua noj; Sib tsoo log rau kev sib tsoo tsheb log tsheb, xuab zeb tom qab pleev xim rau ntawm ntoo, thiab lwm yam kuj tseem muaj ntau yam hauv kev lag luam, xws li kev sib tsoo log rau kev sib tsoo laum me ntsis, sib tsoo lub log rau kev sib tsoo ntau lub pob zeb, lub xov tooj txawb iav sib tsoo pas nrig rau kev sib tsoo xov tooj ntawm tes, iav xuab zeb riam thiab reaming sib tsoo pas nrig rau lub xov tooj ntawm tes kov npo, pom hniav rau kev sib tsoo golf qws, pob zeb yuav tsum tau hauv av los ntawm lub tuam txhab cov cuab yeej, lub tuam txhab sib tsoo log, ntau yam ntaub ntawv, puab qhov sib tsoo pas nrig rau sib tsoo puab lub qhov, ceramic sib tsoo log rau sib tsoo ceramics, thiab lwm yam. Cov no yog peb feem ntau siv abrasives.
Cov cuab yeej siv rau kev sib tsoo, polishing, txiav, thiab sib tsoo. Lawv feem ntau yog ua los ntawm cov khoom siv dag zog. Tom qab qhov kub thiab txias siab, cov nplej abrasive yog sib koom ua ke rau lub substrate nrog binder, thiaj li ua rau cov khoom abrasive. Nws cov matrix yog raws li cov lus qhia tshwj xeeb thiab cov khoom siv, feem ntau yog hlau. Lub abrasives ntawm cov cuab yeej abrasive feem ntau suav nrog ntuj abrasives, cov khoom siv hluavtaws, cov pob zeb ntuj thiab cov pob zeb dag. Vim tias txhua yam ntawm cov ntaub ntawv muaj lawv tus kheej zoo thiab tsis muaj qhov tsis xws luag, lawv tuaj yeem tsim ntau yam khoom, uas tsim nyog rau kev sib tsoo thiab ua txhua yam khoom. Ntxiv rau pob zeb diamond, muaj tungsten steel, boron nitride thiab lwm yam khoom sib tsoo. Lawv cov yam ntxwv zoo sib xws yog tias lawv muaj zog heev, tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev sib tsoo, thiab tuaj yeem siv rau kev sib tsoo lwm yam khoom siv ntev, tab sis kuj tiv taus siab. Yog li lawv tsim nyog rau kev ua cov ntaub ntawv abrasive. Ntxiv nrog rau kev siv dav hauv kev ua hlau thiab lwm yam kev lag luam kev lag luam, abrasives kuj tau siv ntau lwm yam. Piv txwv li, nws yog siv rau cov ntawv ua, iav polishing, cov khoom ua liaj ua teb thiab cov nplej ua, ceramic polishing, pob zeb kev lag luam polishing, roj hmab kev lag luam sib tsoo, ntoo polishing, thiab lwm yam.
Tib yam yog qhov tseeb rau kev tsim khoom ntawm lub puab qhov sib tsoo pas nrig. Nws yog ib tug tswv cuab ntawm tsev neeg abrasive. Hlau pas nrig ntawm lub hauv paus ntawm lub puab qhov sib tsoo pas nrig yog CBN boron nitride. Los ntawm electroplating thiab lwm txoj kev, cov xuab zeb hais yog plated ntawm lub hauv paus hlau pas nrig nyob rau hauv qhov kub thiab txias. Tom qab txias, nws dhau los ua cov khoom tiav ntawm lub puab qhov sib tsoo pas nrig. Cov xim ntawm sab hauv qhov sib tsoo pas nrig yog cov nyiaj dawb thiab kub, Cov xim ob no muaj zog dua thiab nws yog xim hlau. Nws yog tsuas yog siv rau kev sib tsoo cov npoo, cov ces kaum, reaming thiab drilling ntawm lwm yam khoom.
