Qhov Ua Haujlwm Zoo ntawm Dawb Corundum Micropowder hauv Pob Zeb Polishing
Yog hais qhov tseeb, thaum nws los txog rau "kev txhuam pob zeb," ntau tus neeg thawj zaug xav txog tej zaum yuav yog cov tshuab loj, cov chaw tsim khoom nrov nrov, thiab cov discs sib tsoo hauv tes ntawm cov neeg txhuam uas muaj kev paub dhau los. Tab sis yog tias koj nkag siab txog kev lag luam tiag tiag, koj yuav pom tias feem ntau nws yog cov hmoov me me uas yuav luag tsis pom uas txiav txim siab qhov kawg. Piv txwv li,hmoov av dawb corundumPeb tab tom tham txog hnub no yog tus "master of polishing" uas zais tom qab qhov xwm txheej. Thaum kuv thawj zaug pib ua haujlwm hauv daim teb no, kuv kuj xav tsis thoob: Puas yog nws tsuas yog pob zeb polishing xwb? Txhua "hmoov" tsis muaj teeb meem. Tab sis tom qab pom ntau ntxiv, kuv paub tias kev xaiv cov micropowder zoo tuaj yeem ua rau muaj qhov sib txawv loj heev hauv cov txiaj ntsig.
1. Hmoov dawb corundum yog dab tsi? Vim li cas nws thiaj tsim nyog rau kev txhuam?
Dawb corundum, kom yooj yim hais, yog ib qho tib neeg ua, muaj kev ntshiab siabtxhuas oxide (Al₂O₃). Nws nyuaj dua li cov corundum ntuj, nrog Mohs hardness ntawm 9.0, thib ob tsuas yog pob zeb diamond thiab silicon carbide. Raws li lub npe qhia, "micropowder" txhais tau tias cov khoom uas tau raug tsoo thiab sieved rau micron-level hmoov zoo. Tej zaum koj yuav nug: "Cov khoom no puas yuav khawb lub pob zeb?" Qhov no coj peb mus rau nws qhov zoo: siab hardness tab sis zoo heev toughness: dawb corundum particles yog resistant rau breakage, tswj uniform txiav quab yuam thaum lub sij hawm polishing; tshuaj stability: lawv tsis react nrog minerals hauv lub pob zeb, ua rau tsis muaj discoloration lossis corrosion; thiab heev tswj tau qhov loj me me: lawv muab kev pabcuam tag nrho los ntawm kev sib tsoo ntxhib mus rau polishing zoo, ua rau lawv tshwj xeeb tshaj yog tsim rau ntau theem polishing txheej txheem. Cov yam ntxwv no ua rau nws tshwj xeeb tshaj yog tsim rau kev ua cov pob zeb zoo nkauj xws li marble, granite, thiab pob zeb dag.
II. Dab tsi ua rau nws "ua haujlwm tau zoo" hauv kev txhuam hniav tiag tiag?
Muaj ntau tus neeg xav tias kev txhuam tsuas yog hais txog kev ua kom lub pob zeb ci ntsa iab xwb, tab sis qhov ntawd tsis yog qhov tseeb. Kev txhuam zoo yuav tsum tshem tawm cov khawb sai sai thaum maj mam txhim kho qhov ci ntsa iab, thaum tseem zam kev txhuam ntau dhau lossis ua rau cov noob puas tsuaj.
1. Kev txhuam kom ntxhib, nruab nrab, thiab zoo, ua tiav zoo kawg nkaus
Piv txwv li, thaum ua haujlwm nrog cov plag tsev marble:
Kev txhuam kom ntxhib (80 # -200 #): Siv cov txhuam ntxhib duahmoov corundum dawb(xws li W40-W20) kom sai sai ua kom qhov chaw du thiab tshem tawm cov khawb tob;
Kev txhuam nruab nrab (400 # -800 #): Hloov mus rau hmoov zoo dua (xws li W14-W7) rau kev txhuam thawj zaug;
Kev txhuam zoo (1500 # -3000 #): Txawm tias cov hmoov nrog W3.5 lossis tsawg dua tuaj yeem siv los ua kom tiav zoo li daim iav.
Koj yuav pom tias cov hmoov ntawm tib yam khoom, hauv ntau qhov loj me ntawm cov khoom me me, tuaj yeem siv tau thoob plaws hauv cov txheej txheem polishing, tshem tawm qhov xav tau hloov cov khoom siv ntau zaus - txuag lub sijhawm, kev siv zog, thiab qhov yuam kev.
2. Muaj zog nplaum thiab ceev ceev polishing
Piv rau cov ntaub ntawv ib txwm muaj xws li diatomaceous earth thiab cerium oxide, cov hmoov corundum dawb, nrog nws cov khoom me me ntse (tsis yog spherical), yooj yim nqus mus rau hauv qhov chaw ntawm pob zeb, ua rau kev txiav zoo dua. Peb tau ua qhov kev sib piv: kev txhuam cov granite tib daim nrog cov hmoov corundum dawb tuaj yeem ua tiav qhov ci ntsa iab tib yam hauv 1/3 lub sijhawm tsawg dua li kev txhuam nrog cov ntaub ntawv ib txwm muaj.
3. Tsis xaiv cov khoom siv pob zeb, muaj ntau yam siv tau
Dawb corundumyog qhov siv tau thoob ntiaj teb, txawm tias nws yog marble lossis granite uas muaj cov kua qaub ntau heev. Qhov no yog qhov tseeb tshwj xeeb rau cov pob zeb cuav sib xyaw (xws li quartz), uas muaj cov khoom siv resin thiab cov khoom siv minerals. Ntau cov khoom siv abrasives ib txwm muaj peev xwm ua rau nws ua matte lossis hazy, thaum cov corundum dawb ib txwm muab qhov ntse.
4. Lub neej ntev thiab txo tus nqi tag nrho
Txawm hais tias cov hmoov av dawb corundum yuav kim dua me ntsis rau ib chav dua li qee cov khoom siv ib txwm muaj, nws tsis yooj yim hnav, tiv taus kev laus, thiab muaj kev siv rov qab tau zoo. Feem ntau, ib pawg khoom tuaj yeem npog thaj chaw ntau dua 20% -30%, ua rau nws pheej yig dua rau lub sijhawm ntev.
3. Puas muaj tej yam piv txwv uas siv tau tiag tiag? Puas yog qhov ntawd yeej ua tau zoo tiag?
Cia kuv muab ib qho piv txwv rau koj: Xyoo tas los, ib lub tsev so tau kho dua tshiab. Lub pem teb marble beige tau raug khawb los ntawm ntau xyoo siv thiab muaj qib ci tsawg dua 30. Pab neeg tsim kho thawj zaug siv cov hmoov txhuam zoo li qub, tab sis tom qab peb txheej, cov txiaj ntsig tseem tsis txaus siab. Tom qab ntawd lawv hloov mus rau cov tshuaj txhuam polishing raws li cov hmoov corundum dawb. Tom qab ob txheej xwb, lawv tau txais qib ci ntau dua 75 degrees. Qib ci kawg thaum xa khoom yog ze li ntawm 85. Tus neeg siv khoom tam sim ntawd tau rov ua daim ntawv cog lus. Tus kws ua tes ua taw tau hais ib yam dab tsi tiag tiag los ntawm lub siab: "Qhov no zoo li tau txais riam phom tshiab hauv kev ua si - nws tua cov dab phem sai sai thiab tsis ua rau koj raug mob."
IV. Cov Qauv Kev Loj Hlob Yav Tom Ntej? Puas Yuav Hloov Nws?
Tam sim no, hmoov corundum dawb tswj hwm txoj haujlwm ruaj khov hauv kev txhuam pob zeb, tab sis nws kuj tseem hloov zuj zus:
Qhov loj me me thiab me dua: Nano-qib dawb corundum hmoov (piv txwv li, W1.0 thiab hauv qab) tau pib siv rau kev ua kom zoo nkauj ultra-mirror, tshwj xeeb tshaj yog hauv kev kho kom zoo nkauj thiab kev ua pob zeb kos duab;
Cov ntawv thov ua ke: Piv txwv li, thaum sib xyaw nrog cerium oxide thiab pob zeb diamond hmoov, nws ua tiav lub zog txiav thiab ci ntsa iab, tsim nyog rau cov ntaub ntawv pob zeb tshwj xeeb;
Kev tiv thaiv ib puag ncig thiab kev nyab xeeb zoo dua: Ib tiam tshiab ntawm cov tshuaj txhuam hniav uas siv dej maj mam hloov cov hmoov qhuav qub, txo cov plua plav paug thiab ua rau lawv tsim nyog rau kev siv tshuab;
Xaus Lus: Cov Khoom Me Me, Qhov Cuam Tshuam Loj
Feem ntau, peb tsom mus rau qhov pom tseeb - xws li lub npe ntawm lub tshuab polishing lossis lub koob npe nrov ntawm pab pawg tsim kho - tab sis tsis quav ntsej txog cov ntsiab lus uas cuam tshuam rau cov txiaj ntsig tiag tiag.Hmoov dawb corundum yog ib yam khoom siv uas "tsis tshua muaj neeg paub, tab sis tseem ceeb heev". Yog tias koj tab tom kho koj lub tsev lossis ua haujlwm hauv kev lag luam saib xyuas pob zeb, lub sijhawm tom ntej koj koom nrog hauv cov txheej txheem polishing, koj yuav tsum nug ib lo lus nug ntxiv: "Peb siv hom hmoov me me twg?" Qhov tshwm sim kawg yuav txawv kiag li vim yog lo lus nug no.
