Kev txhuam hniav muaj peev xwm muab faib ua kev txhuam hniav ntxhib, kev txhuam hniav nruab nrab, thiab kev txhuam hniav zoo. Kev txhuam hniav ntxhib yog cov txheej txheem ntawm kev txhuam ib qho chaw nrog lossis tsis muaj lub log tawv, uas muaj qee qhov kev sib tsoo ntawm lub substrate thiab tuaj yeem tshem tawm cov cim ntxhib. Kev txhuam hniav nruab nrab yog kev ua tiav ntxiv ntawm cov chaw txhuam hniav ntxhib siv cov log txhuam hniav tawv dua. Nws tuaj yeem tshem tawm cov khawb uas tshuav los ntawm kev txhuam hniav ntxhib thiab tsim cov chaw ci ntsa iab nruab nrab. Kev txhuam hniav zoo yog cov txheej txheem kawg ntawm kev txhuam hniav, siv lub log mos los txhuam thiab tau txais qhov chaw ci ntsa iab zoo li daim iav. Nws muaj me ntsis kev sib tsoo ntawm lub substrate.
Ⅰ.Lub log txhuam
Cov log txhuam hniav yog ua los ntawm ntau yam ntaub sib txawv, thiab lawv cov qauv feem ntau suav nrog cov hauv qab no:
1. Hom xov: Nws yog ua los ntawm kev xaws daim ntaub ua ke. Cov txheej txheem xov suav nrog lub voj voog concentric, radial, radial arc, spiral, square, thiab lwm yam. Raws li qhov sib txawv ntawm kev xaws thiab cov ntaub, cov log polishing nrog qhov nyuaj sib txawv tuaj yeem ua tau, uas feem ntau yog siv rau kev polishing ntxhib.
2. Tsis muaj xov: Nws muaj ob hom: hom disc thiab hom tis. Txhua lub log tau sib dhos ua ke ua cov log mos siv cov ntaub ntawv, tsim tshwj xeeb rau kev txhuam kom meej. Tis muaj lub neej ua haujlwm ntev dua.
3. Kev tais: Nws yog tsim los ntawm kev tais cov ntaub puag ncig ua ob lossis peb zaug kom ua ib lub "hnab zoo li cas", thiab tom qab ntawd muab lawv tso rau saum ib leeg. Lub log txhuam no yooj yim khaws cov tshuaj txhuam, muaj qhov elasticity zoo, thiab kuj ua rau huab cua txias.
4. Hom kab ntswj: Txiav cov ntaub dov ua 45 daim kab txaij, xaws lawv ua cov yob txuas ntxiv, thiab tom qab ntawd qhwv cov yob ib puag ncig lub tog raj kheej kom ua rau cov duab ntswj. Lub plawv ntawm lub log tuaj yeem muab tso rau hauv daim ntawv cardboard kom lub log haum nrog lub tshuab ncej. Cov log hlau nrog qhov cua kuj tuaj yeem ntsia tau (daim ntawv no zoo dua). Lub yam ntxwv ntawm lub log polishing no yog qhov cua sov zoo, tsim nyog rau kev polishing ceev ntawm cov khoom loj.
Ⅱ. Tus neeg sawv cev txhuam hniav
1. Cov tshuaj txhuam hniav
Cov tshuaj txhuam hniav yog ua los ntawm kev sib xyaw cov khoom siv txhuam hniav nrog cov nplaum (xws li stearic acid, paraffin, thiab lwm yam) thiab tuaj yeem yuav tau hauv khw. Nws cov kev faib tawm, cov yam ntxwv, thiab kev siv tau qhia hauv daim duab hauv qab no.
| Hom | Cov yam ntxwv | Lub Hom Phiaj |
| Cov tshuaj txhuam dawb
| Ua los ntawm calcium oxide, magnesium oxide, thiab cov nplaum, nrog rau qhov me me tab sis tsis ntse, yooj yim rau huab cua thiab puas tsuaj thaum khaws cia ntev. | Kev txhuam cov hlau mos dua (txhuas, tooj liab, thiab lwm yam) thiab cov khoom siv yas, kuj siv rau kev txhuam kom raug |
| Cov tshuaj txhuam polishing liab | Ua los ntawm hlau oxide, oxidized diav, thiab nplaum, thiab lwm yam, Nruab nrab hardness | Kev txhuam cov khoom siv hlau dav dav, rau txhuas, tooj liab thiab lwm yam khoomKev pov cov khoom tsis zoo |
| Cov tshuaj txhuam polishing ntsuab | Siv cov ntaub ntawv xws li Fe2O3, alumina, thiab cov nplaum uas ua los ntawm cov khoom siv sib tsoo muaj zog | Polishing hlau alloy nyuaj, txheej kev, hlau tsis xeb |
2. Kev daws teeb meem
Cov tshuaj txhuam polishing siv rau hauv cov kua txhuam polishing zoo ib yam li cov uas siv rau hauv cov tshuaj txhuam polishing, tab sis tus qub siv rau hauv cov roj lossis dej emulsion ntawm chav tsev kub (cov khoom siv hluav taws xob yuav tsum tsis txhob siv) los hloov cov nplaum khov kho hauv cov tshuaj txhuam polishing, ua rau muaj cov kua txhuam polishing.
Thaum siv cov tshuaj txhuam hniav, nws raug txau rau ntawm lub log txhuam hniav los ntawm lub thawv muab siab, lub thawv muab siab, lossis lub twj tso kua mis nrog rab phom txau. Lub siab ntawm lub thawv pub mis lossis lub zog ntawm lub twj tso kua mis yog txiav txim siab los ntawm cov yam xws li viscosity ntawm cov tshuaj txhuam hniav thiab qhov xav tau. Vim muaj cov tshuaj txhuam hniav tas li raws li qhov xav tau, kev hnav ntawm lub log txhuam hniav tuaj yeem txo qis. Nws yuav tsis tso ntau tus neeg sawv cev txhuam hniav rau ntawm qhov chaw ntawm cov khoom thiab tuaj yeem txhim kho kev ua haujlwm ntau lawm.
