Thaum cov qauv zoo sib xws qhia txog qhov sib txawv ob tus lej ntawm kev puas tsuaj ntawm ob lub chaw kuaj mob, cov khoom siv - tsis yog lub tshuab - feem ntau yog qhov ua rau.
Kev ntsuas kev sib txhuampes tsawg cov khoom ploj mus rau hauv qab qhov kev thauj khoom thiab txoj kev uas tau teev tseg. Kev thauj khoom, qhov ntse ntawm cov khoom siv abrasive thiab qhov xwm txheej ntawm kev sib cuag yog peb yam kev hloov pauv, thiab cov khoom siv tau nqa tag nrho peb yam.
1. Cov Lus Qhia Txog Ib Nthuav Dav
| Txoj Kev | Cov Khoom Siv Tseem Ceeb & Cov Kev Ntsuas |
|---|---|
| MartindaleISO 12947 | Cov tshuaj txhuam plaub mos mos + daim ntaub mos mos (≥ 140 hli); tag nrho qhov hnyav(595 ± 7) g → 9 kPa, (795 ± 7) g → 12 kPaCov ntaub coated (198 ± 2) g → 3 kPa nrog 600 # daim ntawv tsis muaj dej |
| TaberASTM D3884 | Calibrate log CS-10/CS-17, Calibrate H-18/H-22; nqa tes 250 g, qhov hnyav muab500 / 1000 g; S-33 (360 FEPA), S-42 (180 ANSI-CAMI) |
| DINISO 4649 | Aluminium oxidexuab zeb 60daim ntawv, ~474 × 402 hli; lub zog ntsug10 N; 40 m hla |
| CrockmeterAATCC 8 / ISO 105-X12 | Daim ntaub paj rwb txheem; ntiv tes(16 ± 0.1) hlidia., 19 × 25.4 mm thaiv rau pawg; zog(9 ± 0.2) Ntxoj kab (104 ± 3) hli |
Cov qib tsis tuaj yeem hloov pauv tau: CS-10 ua rau muaj kev hnav me ntsis, H-18 txiav nyuaj dua - cov txiaj ntsig tuaj yeem txawv ntau npaug.
2. Kev Hloov Kho & Kev Kho Dua Tshiab
| Khoom siv tau | Cov Qauv |
|---|---|
| Martindale abradant & felt | Tau hloov kho dua tshiab ua ntej txhua qhov kev xeem; txhua 50,000 rubs ntawm kev khiav ntev dua |
| Cov ntawv xuab zeb Taber | Txhua200–500 lub voj voog |
| Cov log tsheb | So haujlwm thaum44.4 hli (1.75 nti)txoj kab uas hla — mus txog rau ntawm daim ntawv lo. Calibrate log tas sij hawm |
| Taber refacing | Cov log tsheb tshiab 2 × 50 lub voj voog; 25 lossis 50 ua ntej kev sim.Ib lub disc S-11 siv tau ib zaug xwb |
| DIN abrasive daim ntawv | Siv tau thaum qhov kev poob ntawm qhov siv los ua piv txwv tseem nyob hauv180–220 mg; saum 220 mg ces ntse dhau lawm, hauv qab 180 mg ces ntse dhau lawm |
⚠️
Qhov kev ua tsis tiav uas txaus ntshai tshaj plaws.Ib daim kab xev lossis daim ntaub abradant uas siv ntau dhau nyeem taucuav qis, yog li ntawd cov khoom tsis ua raws li txoj cai dhau mus.
3. Tshem tawm · Sib dhos · Ruaj ntseg
- Tsis txhob kovsiv tes liab qab los yog lub ntsej muag ntiv tes; tsis txhob khoov daim ntawv DIN.
- Khaws lub taub hau kom sib npaug nrog lub turntable (feem ntau ≤0.05 hlieccentricity); siv cov strips tiaj tus.
- Nias kom nruj raws kab pheeb ces kaum ua ntu zus; khiav tawm kom paub tseeb tias tsis muaj suab nrov lossis co.
A zoo li lub hli crescentcim es tsis yog lub nplhaib sib npaug txhais tau tias qhov tsis sib xws lossis lub ntsej muag log tsis sib npaug.
4. Rov kho dua tom qab txhua qhov kev hloov pauv
- Martindale— xyuas kom tseeb tias 595 g / 795 g rau 9 kPa / 12 kPa
- Taber— rhuav cov log tshiab 2 × 50; xyuas kom tseeb tias hnyav 250/500/1,000 g; txhuam cov khib nyiab tawm
- DIN— rov kuaj xyuas dua nrog cov tshuaj siv piv txwv li txhua 10 qhov kev sim; rov kuaj dua yog tias qhov kis tau ntau tshaj 15 mg
- Crockmeter— xyuas kom tseeb 9 N thiab qhov ntev ntawm txoj kab; mob raws li ISO 139
5. Cov Khoom Tseem Ceeb Rau Kev Khaws Cia
Tswj tau qhov kub thiab av noo (yuav tsum muaj rau S-42 strips); tiaj tus, tsis muaj dab tsi, tsis khoov; cov tshuaj ntxuav plaub mos mos thiab daim ntaub paj rwb raws li ISO 139; foob thiab hnub tim uas seem.
Hauv ib kab:tsis yog hais txog kev hloov pauv ntau zaus -Txoj kev zoo, lub sijhawm teev cia, kev teeb tsa sib dhos, kev kho dua tshiab tom qab hloov pauv, kev khaws cia tswj tau.
