Dab tsi yog cov abrasives thiab lawv yog dab tsi

Abrasive yog ib yam khoom ntawm ib qho hardness thiab ntom uas tso cai rau lwm cov ntaub ntawv los ntawm kev tshem tawm cov khoom nws tus kheej. Piv txwv li, ib qho ntawm cov haujlwm tshaj plaws uas tuaj yeem ua nrog abrasives yog polishing ntawm ib qho chaw lossis polishing ntawm tib yam. Lawv kuj tuaj yeem siv rau ntau lub hom phiaj.

Abrasives yog cais raws li hardness, grain loj, thiab cov khoom abrasive. Txhua qhov kev hloov pauv no cuam tshuam rau qhov kawg tshwm sim. Xaiv qhov zoo abrasive yog qhov tseem ceeb kom ua tiav qhov xav tau.

Lawv ua dab tsi

Abrasives yog lub hauv paus chiv keeb los yog hluavtaws. Lawv txawv tsuas yog los ntawm lawv cov degree ntawm hardness. Nws tau hais tias ib qho khoom tuaj yeem cuam tshuam lwm tus thaum ib tus kov lwm tus ntawm lawv qhov kev sib cuag. Lawv qib hardness yog ntsuas los ntawm kev ntsuas tshwj xeeb (Knopp, Mohs, thiab lwm yam).

Cov khoom siv tawv tawv tshaj plaws tam sim no nyob rau hauv qhov xwm txheej yog pob zeb diamond. Kuj tseem muaj lwm cov ntaub ntawv ntawm ob qho tib si ntuj thiab hluavtaws, xws li silicon carbide, corundum, thiab zirconium. Cov no tsis ncav cuag tib lub hardness li pob zeb diamond, tab sis lawv nyob ze rau nws.

Yuav kom ua tau ib qho abrasive, yuav tsum muaj kev txhawb nqa los ua cov hmoov abrasive. Cov kev txhawb nqa siv feem ntau yog ntawv lossis canvas. Resin los yog kua nplaum yog siv los kho cov abrasive. Cov cuab yeej abrasive tseem ceeb yog ua li no. Piv txwv yog cov ntawv abrasive (tseem hu ua sandpaper), abrasive strips, thiab lwm yam. Txhawm rau tsim cov cuab yeej nyuaj xws li discs thiab lub log nrov plig plawg, yuav tsum muaj cov txheej txheem nyuaj me ntsis uas koom nrog kev siv cov tshuab ua haujlwm.

 

 

Lawv siv thiab siv lawv li cas
Abrasives feem ntau yog siv hauv kev lag luam. Lawv yog cov tseem ceeb tshwj xeeb hauv metallurgical thiab automotive kev lag luam. Ntau yam khoom siv yog tsim los ntawm cov khoom siv abrasives. Sim xav txog lub cev ntawm lub tsheb. Cov khoom uas ua rau lub tsheb yog welded ua ke, tsim burrs ntawm cov hlau pob qij txha. Tshem tawm vuam burrs yog kev ua haujlwm los ntawm kev siv cov abrasives.

Ntawm qhov tod tes, craftsmen thiab cov tub txawg kuj siv abrasives los ua tej yam hauj lwm. Piv txwv li, cov kws ntoo thiab cov neeg ua haujlwm ntoo siv cov abrasives rau cov xuab zeb thiab ua kom tiav qhov chaw ntawm parquet. Tsis tas li ntawd, ntau tus kws kos duab kos duab siv cov abrasives los tsim cov rooj tog lossis cov duab kos duab. Cov kws kos duab siv cov abrasives los tsim thiab txiav stainless hlau. Nrog cov cuab yeej zoo, koj tuaj yeem tsim cov duab kos duab txawv txawv. Abrasives yog qhov zoo tshaj plaws txhais tau tias ua kom tiav cov haujlwm no. Nrog kev pab los ntawm abrasives, koj muaj peev xwm muab cov khoom tiav ib tug flawless nto thiab tau ib tug glossy los yog matte nto raws li koj xav tau kev pab.

Zoo, kev ntxhib los mos, thiab loj
Kev sib txawv abrasives sib txawv ntawm ntau hom kev ua haujlwm, yog li muaj kev sib tsoo disc, sib tsoo log, sib tsoo log, riam, thiab ntau yam ntaub ntawv. Lawv feem ntau txawv ntawm cov duab, qhov loj, thiab grit.

Xaiv qhov zoo abrasive zoo yog qhov tseem ceeb rau kev ua cov nto. Kev siv cov abrasive zoo tshaj plaws pab kom ua tiav cov txiaj ntsig xav tau. Piv txwv li, ob qho tib si tiaj thiab conical abrasive discs tuaj yeem siv rau qhov chaw tiaj tus. Cov qub muab kev sib tsoo ntau dua rau ntawm qhov chaw nqaim, thaum lub sijhawm tom kawg tso cai rau koj ua haujlwm ntau dua rau ntawm qhov loj dua. Rau cov ces kaum los yog khib-zoo li tus nto, khob-zoo li tus abrasives raug pom zoo.

Lub grit ntawm abrasive cuam tshuam rau kev ceev ceev thiab cov qauv tsim. Abrasives nrog grit ntawm 8 thiab 16 feem ntau yog ntxhib heev. Lawv tsim nyog rau tsim cov qauv sib sib zog nqus ntawm qhov chaw. Abrasives nrog grit ntawm 20 thiab 40 (nruab nrab grit) yog tsim rau kev siv dav thiab ntau yam kev siv. Thaum kawg, abrasives nrog grit saum toj no 120 yog nplua-grained abrasives thiab yog siv los ua kom tiav.

Lawv kuj muaj nyob rau hauv ntau qhov ntau thiab tsawg kom haum rau cov cuab yeej koj muaj thiab cov haujlwm uas yuav tsum tau ua.
