silicon carbide VS aluminium oxide

Xaiv cov ntawv xuab zeb kom raug / abrasive tuaj yeem ua rau cov txheej txheem sanding / sib tsoo siv sijhawm tsawg dua los ntawm kev ua kom lub ntsej muag sai dua. Koj tuaj yeem txhim kho qhov chaw tiav los ntawm kev siv cov abrasives tshwj xeeb, cov tswv yim, thiab kev sib zog, nyob ntawm cov khoom siv. Txoj cai abrasives yuav txo kev sib txhuam thiab kub, cia koj khaws cov abrasive ntev dua thiab tsis txhob hlawv cov khoom.

 

Dab tsi yog Aluminium Oxide Abrasives siv rau?

 

Aluminium oxide sandpaper yog cov khoom siv dav siv ntau tshaj plaws vim nws ua haujlwm zoo heev ntawm feem ntau cov hlau, ntoo, thiab cov xim pleev xim. Cov khoom siv tau ruaj khov thiab pheej yig dua los tsim dua li feem ntau ntawm cov kev xaiv thiab.

 

Aluminium oxide abrasives tuaj hauv cov xim sib txawv. Koj tuaj yeem pom xim av, dawb, thiab paj yeeb aluminium oxides, nrog rau xim av yog feem ntau.

 

Dawb thiab liab dawb yuav hnav sai dua, tab sis lawv ua kom tiav smoother. Ob qho txhuas oxides no piv feem ntau rau silicon carbide. Koj tuaj yeem pom cov dawb aluminium oxide hauv ntxhib los ntawm kev ntxhib los mos zoo. Nws ua haujlwm zoo tshaj plaws ntawm ntoo thiab lacquers vim nws ua kom sov tsawg. Koj tuaj yeem siv cov nplej dawb ntawm cov tsho loj ntawm cov ntoo. Pink aluminium oxide los ntawm ntxhib los ntawm kev ntxhib los mos, thiab koj tuaj yeem siv nws ntawm cov ntoo softer.

 

Brown aluminium oxide kav ntevtxij li thaum nws cov nplej zom qeeb qeeb dua li cov xim liab thiab dawb ntau yam. Koj tuaj yeem pom nws hauv ntxhib los ntawm micro-grit textures, thiab nws tuaj yeem xuab zeb cov ntaub ntawv hardness xws li hlau, phab ntsa ntub dej, fiberglass, ntoo, thiab pleev xim rau saum npoo. Thaum lub npoo tiav tsis zoo li zoo li liab dawb lossis dawb, koj tuaj yeem pheej yig dua thiab ceev nrooj zom koj cov khoom nrog xim av aluminium oxide.

 

Koj nrhiav taufriable, semi-friable, tsis tu ncua, thiab hnyav-duty aluminium oxides. Hloov ntawm dulling cia, friable abrasive nplej zom kom rov ua kom rov qab thaum siv, tas li nthuav tawm cov npoo ntse. Coarser grits tuaj yeem tshem tawm cov khoom siv hlau los ntawm kev cia cov nplej rov ua dua li no, thaum cov nplej me tuaj yeem ua tiav cov hlau.

 

Brown aluminium oxide yog semi-friable. Cov nplej yuav tawg thiab rov ua dua, tab sis lawv siv ntau dua los ua kom tawg. Qhov txiaj ntsig ntawm qhov no yog qhov ntev abrasive.

 

Yog tias koj siv aluminium oxide sanding siv, koj yuav pom cov tsho qhib, kaw, thiab hloov tau yooj yim kaw. Ib lub tsho qhib ua haujlwm zoo tshaj plaws ntawm cov hlau mos thiab ntoo vim nws 60% - 65% cov qoob loo.

 

Kaw cov tsho tiv no npog 90% - 95% ntawm txoj siv tawv, ua cov txheej txheem no yog qhov tsim nyog tshaj plaws rau cov hlau tsis muaj hlau thiab ferrous. Thaum kawg, qhov hloov tau yooj yim kaw lub tsho tiv no siv rau qhov chaw so thiab nkhaus ntawm cov ntoo thiab hlau.

Koj tsuas tuaj yeem siv aluminium oxide sanding siv rau kev ua haujlwm qhuav. Yog tias koj npaj yuav siv lub log sib tsoo hlau, koj tuaj yeem siv aluminium oxide ntawm cov ntaub ntawv nrog lub zog tensile siab, zoo li stainless hlau thiab siab tensile bronze thiab aluminium alloys.

 

Dab tsi yog Silicon Carbide Abrasives siv rau?

 

Silicon carbide sandpaper yog qhov nyuaj tshaj plaws thiab ntse tshaj plaws abrasive, tab sis nws tsis muaj zog vim nws cov brittleness. Tsis tas li ntawd, qhov nqaim particle loj hnav sai dua. Cov nplej yog rab chais ntse kom lawv tuaj yeem xuab zeb hlau, marble, iav, pob zeb, cork, nruab nrab-qhov ntom ntom fiberboard, thiab yas nrog lub siab tsawg. Txawm li cas los xij, lawv tawm tsam rau xuab zeb nyuaj hlau thiab ntoo.

 

Silicon carbide ua haujlwm zoo rau ntawm qhov chaw ntxhib thiab polishing. Nws yog friable ntau dua aluminium oxide, thiab koj tuaj yeem siv nws hauv kev ua haujlwm ntub dej. Koj tuaj yeem polish qhov chaw hauv kev siv tsheb, tshem tawm xeb, kho cov plag tsev ntoo, cov hlau deburr, cov iav du, thiab cov xuab zeb ntawm cov tsho loj.

 

Cov neeg feem coob siv silicon carbide sandpaper ua ke nrog txhuas oxide. Cov neeg yuav ua cov xuab zeb ntxhib nrog aluminium oxide abrasives thiab ua tiav qhov project nrog silicon carbide. Ua li ntawd, koj tuaj yeem tsim kom zoo nkauj tiav yam tsis tau hnav koj daim ntawv xuab zeb.

 

Koj tuaj yeem pom friable (ntsuab) thiab tsis tu ncua (dub) silicon carbide, nrog rau cov friable yog purer thiab nyuaj tsis tau nkig ntau dua li niaj zaus.

 

Dub silicon carbidetuaj yeem zom cov hlau tsis-ferrous, ceramics, thiab tawv nonmetals, thaum xaiv ntsuab ua haujlwm zoo tshaj plaws rau polishing lub hom phiaj. Txawm li cas los xij, nws tsis pom zoo kom grind steel nrog silicon carbide.

 

Silicon carbide sanding siv ua haujlwm zoo ntawm cov ntaub ntawv nyuaj xws li ntoo tiav, pob zeb, hlau, xim, thiab cov softer xws li roj hmab, iav, thiab yas. Cov nplej yuav microfracture nrog rov siv dua (friability), ua rau lawv tsis haum rau softwood vim lawv yuav tsis sharpen ntug. Cov hnab looj tes no muaj lub tsho kaw nrog lub ntsej muag zoo tshaj plaws, yog li koj tuaj yeem siv cov nplej rau cov khoom siv tawv los yog ua tiav qhov chaw nrog sealers lossis lacquers.

 

Cov log sib tsoo thiab cov xuab zeb xuab zeb ua haujlwm zoo ntawm cov ntaub ntawv xws li cam khwb cia hlau, aluminium, thiab cemented carbide. Yog tias koj qhov project cuam tshuam nrog cov khoom siv uas tsis yog xim hlau lossis tsis muaj zog tensile, koj yuav xav siv silicon carbide es tsis yog txhuas oxide.
