Koj tab tom yuav khoom siv xuab zeb, thiab tus neeg muag khoom taw qhia rau ob qho kev xaiv ntawm lub txee:
"Qhov no ceramic abrasive siv ob zaug ntau npaum li qhov txhuas oxide ib."
Koj tam sim xav:
"Lawv ob leeg zom cov hlau. Vim li cas cov ceramics thiaj li kim dua? Yog tias kuv yuav tus nqi pheej yig dua thiab hloov nws ntau zaus, nws puas yuav raug nqi ntau dua - zoo?"
Qhov no yog ib lo lus nug uas tshwm sim txhua hnub hauv khw muag khoom thoob ntiaj teb.
Niaj hnub no, peb yuav siv ob qho tib si cov ntaub ntawv tseeb thiab tiag- ntiaj teb tus nqi tsom xam los nthuav tawm qhov twg tus nqi sib txawv ntawm cov ceramic abrasives thiab aluminium oxide abrasives (xws li xim av fused alumina thiab dawb fused alumina) tiag tiag los ntawm.
1. Ntau lub hauv paus chiv keeb: Lawv ua li cas?
Yuav kom nkag siab tias yog vim li cas ceramic abrasives raug nqi ntau dua, peb yuav tsum xub nkag siab tias lawv tsim tau li cas.
Aluminium Oxide Abrasives: Cov Neeg Ua Haujlwm Ua Haujlwm
Aluminium oxide, feem ntau hu ua fused alumina, suav nrog cov khoom xws li xim av fused alumina thiab dawb fused alumina.
Cov txheej txheem tsim khoom yog ib txwm ua. Cov ntaub ntawv nyoos xws li bauxite yog yaj hauv qhov cub hluav taws xob ntawm qhov kub siab heev. Tom qab txias thiab crushing, cov khoom raug tshuaj xyuas rau hauv ntau qhov sib txawv grit.
Yam ntxwv:High hardness thiab tsim nyog toughness. Txawm li cas los xij, nws cov qauv microscopic yog ib qho siv lead ua. Xav txog nws zoo li lub khob qab zib- nyob rau hauv siab, nws tuaj yeem tiv taus qee qhov quab yuam, tab sis thaum qhov txwv tau mus txog, nws tawg tag nrho.
Ceramic Abrasives: High-Tech Newcomer
Txoj kev loj hlob ntawm ceramic abrasives (SG los yog TG abrasives) sawv cev rau ib tug loj technological breakthrough nyob rau hauv abrasive manufacturing.
Lawv raug tsim los ntawm kev siv cov txheej txheem sol-gel, uas suav tsis txheeb microscopic lossis txawm nanoscale crystals yog chemically bonded thiab sintered ua ke los tsim ib qho abrasive grain.
Yam ntxwv:Es tsis txhob ua ib qho khoom siv lead ua, txhua cov nplej muaj ntau txhiab microcrystals. Xav txog kev hloov ib lub suab thaj nrog lub zog compressed bar. Nws tseem muaj zog, tab sis nyob rau hauv siab, txheej ntawm microcrystals maj mam tawg, tsis tu ncua nthuav tawm tshiab ntse txiav npoo.
2. Qhov sib txawv ntawm cov tub ntxhais kawm: Kev sib ntaus sib tua Microscopic thaum sib tsoo
Vim li cas cov qauv nplej sib txawv tsim cov nqi sib txawv? Cov lus teb nyob rau hauv yuav ua li cas cov abrasives ua thaum sib tsoo.
1. Tus kheej -Sharpening Peev Xwm: Qhov Kev Sib Tw Loj Tshaj Plaws
Aluminium Oxide Abrasives
Aluminium oxide abrasives paub dab tsi tuaj yeem piav qhia tias "tag nrho hnav."
Raws li cov nplej ua npub, nws nyuaj rau ib qho - cov qauv siv lead ua kom tawg nyob rau hauv txoj kev uas nthuav tawm cov npoo tshiab. Nyob rau tib lub sijhawm, cov qoob loo tsim ib qho chaw tiaj tus, kev sib txhuam nce, thiab kub nce mus txog thaum tag nrho cov nplej yog thaum kawg rub tawm ntawm txoj siv xuab zeb.
Qhov tshwm sim:Cov nplej ua npub ntev ua ntej nws noj tag nrho.
Thaum cov neeg ua haujlwm hais tias,"Txoj siv tsuas yog tsis txiav lawm,"qhov no feem ntau yog qhov lawv tab tom ntsib.
Ceramic Abrasives
Ceramic abrasives muaj ib qho tshwj xeeb microcrystalline tus kheej -sharpening yam ntxwv.
Thaum ib qho microcrystal ua npub, lub tshav kub thiab kev sib tsoo quab yuam ua rau cov microcrystal tshwj xeeb kom tawg, nthuav tawm ib hom npe - tshiab ntse microcrystal hauv qab.
Qhov tshwm sim:Lub abrasive tseem ntse ntse thoob plaws hauv nws lub neej ua haujlwm.
Nws zoo li muaj riam phom Swiss Army uas yeej tsis ua npub -thaum ib ntug hnav, ib ntug tshiab tam sim ntawd yuav nws qhov chaw.
2. Thaum tshav kub kub ua hauj: tseem ceeb heev rau workpiece tiv thaiv
Thaum lub sij hawm siab - sib tsoo ceev, cua sov feem ntau yog tus yeeb ncuab loj tshaj plaws.
Nrog aluminium oxide abrasives, ib zaug cov nplej ua npub, kev sib txhuam nrawm nrawm. Qhov no tuaj yeem ua rau kub hnyiab, tawg, thiab txawm tias microcracks hauv qhov chaw ua haujlwm -tshwj xeeb tshaj yog thaum sib tsoo stainless hlau lossis titanium alloys.
Vim tias ceramic abrasives nyob twj ywm ntse, lawv txiav tau zoo nrog kev sib txhuam tsawg. Yog li ntawd, kev tsim hluav taws xob tau txo qis. Cov ntaub ntawv ceramic kuj muaj cov cua sov ua haujlwm zoo, tso cai rau ntau lub tshav kub tawm nrog cov chips es tsis txhob nkag mus rau hauv cov khoom ua haujlwm.
Qhov no pab tiv thaiv thermal puas thiab tiv thaiv kev ncaj ncees ntawm cov khoom ua tiav.
3. Wb Ua lej: Cov Ceramic Abrasives puas kim dua?
Ntau tus tswv khw xav tias:
"Ceramic sanding bets raug nqi ob lossis peb zaug ntau dua li cov siv tawv aluminium oxide. Lawv kim heev."
Tab sis tus qauv tiag tiag yuav tsum yog:
Tus nqi tag nrho=Abrasive Purchase Price ÷ (Kev Pabcuam Lub Neej × Sib Tsoo Ua Haujlwm) + Tus Nqi Ua Haujlwm + Tus Nqi Ua Haujlwm
Cia peb sib piv ib daim ntawv thov nto sib tsoo:
| Qhov xwm txheej | Aluminium Oxide Belt | Ceramic Belt |
|---|---|---|
| Tus nqi yuav khoom | 1x | 2.5x |
| Kev Pabcuam Lub Neej | Lub hauv paus (1x) | 3-8x ntev dua (tshwj xeeb yog nyob rau hauv kev sib tsoo hnyav) |
| Sib tsoo Efficiency | Lub hauv paus (1x) | 1.5-2x siab dua (ua tau ceev pub tus nqi tau) |
| Belt Hloov zaus | Nquag (piv txwv li, ib zaug ib teev) | Tsawg heev (piv txwv li, ib zaug hauv ib hnub) |
| Workpiece Yield | Riam kub hnyiab thiab khawb | Stable, ho txhim kho tawm los |
Lub ntsiab lus
Yog tias koj tsuas saib tus nqi yuav khoom, ceramic abrasives yog undeniably kim dua.
Txawm li cas los xij, yog tias koj suav cov nqi siv tau rau ib qho haujlwm tiav, ceramic abrasives feem ntau yog qhov kev xaiv pheej yig dua.
Thiab qhov ntawd yog ua ntej txiav txim siab txog kev txuag nyiaj los ntawm kev txo qis qis, hloov siv txoj siv tsawg dua, thiab cov nqi qis dua.
4. Koj yuav tsum xaiv qhov twg?
Tsis yog txhua daim ntawv thov yuav tsum tau ceramic abrasives. Qhov tseem ceeb yog xaiv qhov zoo abrasive, tsis yog qhov kim tshaj plaws.
Xaiv Aluminium Oxide (xim av los yog Dawb Fused Alumina) Thaum:
- Sib tsoo me me hlau los yog cam khwb cia hlau.
- Ua lub teeb- siab phau ntawv sib tsoo.
- Ua hauj lwm rau kev ua tiav daim ntawv thov qhov chaw zoo yog qhov kev txhawj xeeb tseem ceeb (dawb fused alumina tseem yog qhov kev xaiv zoo tshaj).
- Kev ua haujlwm nrog kev siv nyiaj tsawg heev thiab kev tsim khoom tsim nyog yuav tsum tau ua.
Xaiv Ceramic Abrasives Thaum:
- Sib tsoo cov ntaub ntawv nyuaj xws li stainless hlau (304, 316, thiab lwm yam), titanium alloys, superalloys, los yog cov cuab yeej hardened.
- Ua haujlwm hnyav- kev sib tsoo nrog kev kub siab thiab kev tshem tawm cov khoom hnyav.
- Siv cov tshuab sib tsoo tshuab, CNC grinders, lossis hnyav- cov khoom siv sib tsoo.
- Khiav automated ntau lawm kab uas abrasive sib xws thiab kev pab cuam lub neej yog ib qho tseem ceeb tshaj li thawj tus nqi yuav khoom. Kev hloov txoj siv tsawg dua txhais tau tias tsis muaj sijhawm poob qis thiab ua haujlwm ntau dua.
- Kev tsim khoom siab -cov khoom muaj txiaj ntsig xws li cov khoom siv dav hlau, cov khoom siv kho mob, lossis cov pwm pwm. Txawm tias 1% seem tus nqi los ntawm kev sib tsoo kub tuaj yeem raug nqi ntau dua li qhov abrasive nws tus kheej.
Kev xav zaum kawg
Ceramic abrasives yog kim dua vim tias cov thev naus laus zis siab heev ua rau lawv cov qauv microscopic.
Koj tab tom them rau lawv tus kheej microcrystalline - muaj peev xwm ua kom ntse, lawv lub peev xwm nyob twj ywm ntse thoob plaws hauv cov txheej txheem sib tsoo, thiab kev txuag nyiaj lawv tsim los ntawm kev txo qis qis, txo nqi zog, thiab tsawg dua qhov tsis lees paub.
Nyob rau hauv lub ntiaj teb niaj hnub no ntawm kev ua haujlwm siab -kev ua tau zoo thiab kev tsim khoom, cov khoom siv abrasives tsis yog cov khoom siv ntxiv lawm- lawv yog qhov txiav ntawm kev tsim khoom lag luam.
Lub sij hawm tom ntej koj tab tom xaiv ntawm sanding siv, nug koj tus kheej:
Koj puas xav tau txoj siv tawv uas pheej yig tshaj plaws, lossis ib qho uas tuaj yeem pab koj khwv tau nyiaj ntau dua?
