Kev yuavDub Silicon Carbidetsis yog tsuas yog ib qho teeb meem ntawm kev xaiv grit loj thiab thov rau cov lus hais. Rau cov neeg yuav khoom lag luam, ib qho ntawm cov lus nug tseem ceeb tuaj tom qab: Koj yuav ua li cas thiaj paub tseeb tias cov khoom koj tau txais yog qhov tsim nyog rau kev tsim khoom? Tus neeg muag khoom tuaj yeem muab cov khoom lag luam tshwj xeeb, cov ntaub ntawv qhia kev, lossis Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (COA), tab sis tsis yog txhua tus neeg yuav khoom paub cov ntaub ntawv twg tsim nyog tau txais kev saib xyuas tshaj plaws. Kev ua tau zoo- cov txheej txheem kuaj xyuas tuaj yeem pab cov tuam txhab txo qis qhov sib txawv ntawm cov qauv sim thiab cov khoom xa tuaj, tshwj xeeb tshaj yog thaum kev ua haujlwm abrasive nyob ntawm cov yam ntxwv ruaj khov.
Pib Nrog Cov Khoom Specification.
Ua ntej tshuaj xyuas cov ntaub ntawv hauv chav kuaj, xyuas kom tseeb tias cov ntaub ntawv ntawm cov khoom lag luam muaj tseeb. Xyuas seb cov ntaub ntawv puas qhia meej: Cov khoom npe; Grit los yog particle loj; Qib; Cov qauv siv tau; Batch naj npawb; Hnub tsim khoom; Cov ntaub ntawv ntim khoom; Qhov no suab yooj yim, tab sis nws yog thawj kauj ruam tseem ceeb.
Daim ntawv tshaj tawm kev xeem no muaj txiaj ntsig tsuas yog thaum koj tuaj yeem txuas nws mus rau cov khoom siv tiag tiag. Piv txwv li, ib daim ntawv tshaj tawm rau ib qho me me yuav tsum tsis txhob raug kho raws li pov thawj rau lwm qib.
Saib Chemical Composition - Tab sis Tsis Txhob Nres.
Cov tshuaj muaj pes tsawg leeg yog ib qho ntawm feem ntau tshuaj xyuas ntu ntawm COA. Raws li qhov tshwj xeeb, cov neeg yuav khoom yuav them sai sai rau SiC cov ntsiab lus thiab qib impurity xws li: dawb silicon; Dawb carbon; Hlau; Aluminium; Calcium; Lwm yam hlau lossis ntxhia impurities; Kev purity siab dua tuaj yeem yog qhov tseem ceeb rau cov ntawv thov uas muaj tshuaj lom neeg ruaj khov, qhov zoo ntawm qhov chaw, lossis cov khoom siv ua haujlwm zoo rau kev sib kis. Txawm li cas los xij, tshuaj muaj pes tsawg leeg ib leeg tsis qhia tag nrho zaj dab neeg. Ob pawg tuaj yeem pom cov txiaj ntsig zoo sib xws thaum coj tus cwj pwm sib txawv yog tias lawv cov khoom faib tawm, cov qoob loo, lossis kev ua haujlwm sib txawv. Tias yog vim li cas kev ntsuam xyuas zoo yuav tsum muab cov ntaub ntawv tshuaj lom neeg nrog cov yam ntxwv ntawm lub cev.
Particle Loj Distribution feem ntau siv tau ntau dua li ib tus lej Grit.
Ib qho ntawm cov ntsiab lus tsis pom zoo tshaj plaws thaum yuav cov nplej abrasive yog qhov sib txawv ntawm lub npe grit thiab qhov tseeb particle- qhov loj me.
Ib yam khoom yuav raug muag nyob rau hauv tib tus lej grit, tab sis kev faib tawm ntawm cov khoom hauv qib ntawd tseem tuaj yeem cuam tshuam rau kev tsim khoom. Rau cov chaw tsim khoom ntawm coated abrasives, cov cuab yeej sib tsoo, lossis lwm yam khoom siv abrasive, particle tis tuaj yeem cuam tshuam: txiav tus cwj pwm; Nto tiav; Cov khoom tshem tawm; Txheej uniformity; Cov khoom sib xws; Yog li ntawd, thaum muab piv rau cov qauv, nug seb puas particle- tswj qhov loj npaum li cas los ntawm batch mus rau batch. Qhov no yog tshwj xeeb tshaj yog muaj txiaj ntsig thaum ntsuam xyuas Black Silicon Carbide grain loj rau cov txheej txheem ntau lawm.
Grain Shape tuaj yeem cuam tshuam rau Abrasive Cwj Pwm.
Tshuaj purity tau txais kev saib xyuas ntau, tab sis cov nplej morphology kuj tsim nyog xav txog. Abrasive hais tsis zoo ib yam. Lawv cov duab, sharpness, tawg yam ntxwv, thiab cov qauv saum npoo tuaj yeem cuam tshuam li cas lawv cuam tshuam nrog kev ua haujlwm lossis kev sib txuas. Rau cov ntawv thov uas yuav tsum tau txiav nruj, cov ntsiab lus txiav ntse tuaj yeem muaj txiaj ntsig. Rau lwm daim ntawv thov, cov yam ntxwv ntawm cov khoom siv tswj tau yuav yog qhov tseem ceeb tshaj qhov tsuas yog ua kom pom tseeb. Cov qoob loo zoo yog li txiav txim siab los ntawm daim ntawv thov es tsis yog los ntawm ib tus lej kuaj.
Tshawb xyuas seb tus qauv sawv cev rau Cov Khoom Siv Loj.
Ib qho qauv tuaj yeem ua tau zoo hauv kev sim, tab sis cov lus nug tseem ceeb dua yog seb cov yam ntxwv zoo li cas yuav nyob ruaj khov thaum lub sijhawm yuav khoom.
Qhov no yog qhov uas batch traceability yuav pab tau. Nug tus neeg muag khoom seb cov khoom puas tuaj yeem txheeb xyuas los ntawm: Batch tooj; Cov ntaub ntawv ntau lawm; Daim ntawv xeem; Ntim daim ntawv lo; Cov ntaub ntawv soj ntsuam; Rau cov neeg yuav khoom rov qab, khaws cov qauv qub thiab cov ntaub ntawv zoo sib xws tuaj yeem ua rau kev sib piv yav tom ntej yooj yim dua. Yog tias kev xa khoom tom qab ua tiav qhov sib txawv, tus neeg yuav khoom muaj cov ntsiab lus siv los tshawb xyuas qhov txawv.
Tsis txhob kho COA raws li kev lees paub ntawm Daim Ntawv Thov Kev Ua Haujlwm.
COA yog ib daim ntawv tseem ceeb, tab sis nws yuav tsum tsis txhob to taub yuam kev. Ib daim ntawv tshaj tawm hauv chaw soj nstuam ib txwm lees paub cov yam ntxwv uas tau xaiv tawm tsam cov kev xav tau tshwj xeeb. Nws tsis tuaj yeem lav tias cov khoom siv yuav ua tau zoo tib yam kev ua tiav abrasive hauv txhua qhov kev tsim. Vim li cas? Vim tias qhov kawg tshwm sim kuj tseem nyob ntawm: Bonding system; Kev sib xyaw; Txheej txheej; Kho tej yam kev mob; Tshuab parameters; Cov khoom siv ua haujlwm; Kev tsim khoom ib puag ncig; Yog li ntawd, cov txheej txheem kev yuav khoom muaj zog tshaj plaws ua ke nrog kev txheeb xyuas cov ntaub ntawv nrog rau kev sim cov ntawv thov.
Siv peb -Txoj Kev Tshawb Fawb Txog Qhov Zoo.
Rau kev lag luam kev lag luam, ib qho yooj yim peb -theem mus kom ze tuaj yeem ua rau kev ntsuam xyuas zoo dua.
Cov ntaub ntawv tshawb xyuas
Tshawb xyuas cov kev qhia tshwj xeeb, COA, cov ntaub ntawv xeem, cov ntaub ntawv batch, thiab cov qauv siv tau.
Kev Xeem
Siv tus qauv tus neeg sawv cev hauv koj tus kheej cov txheej txheem tsim khoom. Saib xyuas kev ua tau zoo, nto tiav, noj, thiab kev ruaj ntseg ntau lawm.
Kev lees paub ntau
Tom qab tau txais cov khoom xa tuaj thawj zaug, sib piv nws qhov zoo ntawm cov qauv pom zoo thiab cov ntaub ntawv qub. Qhov no tsim ib qho yooj yim tab sis muaj txiaj ntsig zoo- tswj lub voj: Specification → Qauv → Kev xa khoom loj → Cov lus qhia ntau lawm; Yog tias cov txiaj ntsig tau zoo ib yam, cov khoom yuav yooj yim dua kom tsim nyog rau kev yuav khoom dua.
Cov neeg yuav khoom yuav tsum muab tso rau hauv lawv daim ntawv tshuaj ntsuam xyuas dab tsi?
Hloov chaw ntawm kev tshuaj xyuas kaum ob ntawm cov ntsiab lus tsis muaj qhov tseem ceeb, faib cov kev tshuaj xyuas ua plaub pawg.
| Qeb | Yuav kuaj xyuas dab tsi |
|---|---|
| Tus kheej | Khoom, grit, batch, standard |
| Chemistry | SiC cov ntsiab lus thiab impurities |
| Lub cev muaj zog | Particle faib thiab grain yam ntxwv |
| Kev sib raug zoo | Sample-rau-bulk thiab batch-rau-batch stability |
Cov qauv no ua rau kev sib txuas lus yooj yim dua ntawm lub chaw yuav khoom, pab pawg zoo, thiab tus neeg muag khoom.
Ib lo lus nug muaj txiaj ntsig: "Yuav ua li cas hloov pauv los ntawm pawg dhau los?"
Rau kev yuav khoom dua, qhov no yuav muaj txiaj ntsig ntau dua li nug seb qhov khoom xa tuaj tshiab tsuas yog "dhau mus." Yog tias cov batch yav dhau los ua haujlwm zoo, sib piv cov batch tshiab tawm tsam nws. Nrhiav kev hloov hauv: Tshuaj muaj pes tsawg leeg; Particle faib; Qhov tsos; Cov yam ntxwv ntawm cov nplej; Kev ua haujlwm ntau lawm; Qhov sib txawv me me hauv cov ntaub ntawv kuaj yuav muaj qhov tseem ceeb me me hauv ib daim ntawv thov tab sis ua qhov tseem ceeb hauv lwm qhov. Qhov tseem ceeb yog kom nkag siab tias qhov twg ua tau cuam tshuam rau koj txoj kev tsim khoom.
Yuav ua li cas los tsim kom tau ib tug zoo dua dub Silicon Carbide zoo Standard?
Rau ntev - kev yuav khoom, cov neeg yuav khoom tuaj yeem tsim cov khoom siv sab hauv raws li cov kev xav tau tiag tiag. Tsis yog sau ntawv xwb:
"Dub Silicon Carbide, txheem grit."Ib qho kev yuav khoom muaj zog tuaj yeem txheeb xyuas: Yuav tsum tau grit; Kev txwv tshuaj lom neeg; Particle- qhov xav tau loj; Ntim; Kev soj ntsuam xyuas; Qauv kev pom zoo; Batch kev cia siab; Qhov no ua rau yav tom ntej cov lus sib piv tau yooj yim dua thiab txo cov teeb meem kev sib txuas lus. Nws kuj tseem tso cai rau koj pab neeg yuav khoom los ntsuas cov neeg xa khoom tshiab tawm tsam tib lub hauv paus txheej txheem.
Qhov zoo ntawm Black Silicon Carbide yuav tsum tsis txhob txiav txim los ntawm cov tsos lossis tus nqi ib leeg. Ib txoj hauv kev txhim khu kev qha ntau dua yog txhawm rau txuas cov ntaub ntawv thev naus laus zis, cov yam ntxwv ntawm cov khoom, cov qauv kuaj, thiab cov khoom loj- pov thawj cov khoom xa tuaj. Rau cov neeg yuav khoom, cov lus nug tseem ceeb tshaj plaws tsis yog qhov yooj yim:
"Cov khoom no puas ua tau raws li qhov tshwj xeeb?" Nws yog: "Cov khoom no puas tuaj yeem ua tau raws li qhov tshwj xeeb thiab ua haujlwm hauv kuv cov txheej txheem ntau lawm?" Qhov kev hloov ntawm kev xav no tuaj yeem ua rau cov khoom siv raw khoom abrasive - kev yuav khoom ntau dua.
