Dub Silicon Carbide (Sic)Yog ib qho khoom tseem ceeb thiab tsis siv cov khoom lag luam thiab kho kom dav dav siv hauv kev ua hlau, kev lag luam refractory, thiab semiconductor kev lag luam. Txawm li cas los xij, kev ua lag luam yog dej nyab nrog cov khoom lag luam sib txawv, thiab ntau tus neeg yuav khoom poob rau hauv cov ntsiab lus zoo li tsis tshua muaj kev cuam tshuam, lossis overpaying rau cov khoom seem.
Vim Li Cas Composition Testing tsis yog - sib ceg: sic cov ntsiab lus & Free}} changers
Kev ua yeeb yam ntawm cov dub silicon carbide ncaj qha yog yog nyob ntawm nws cov tshuaj lom neeg muaj pes tsawg leeg. Ntawm txhua qhov ntsuas, SIC cov ntsiab lus thiabCov pa roj carbon dawbCov ntsiab lus yog ob qho tseem ceeb tseem ceeb uas paub qhov txawv siab - cov khoom lag luam zoo los ntawm qis dua. Tsis quav ntsej cov kev sim no tuaj yeem ua rau cov khoom lag luam ntau lawm, cov nqi nce, thiab txawm tias cov khoom tsis xws luag.
1. Sic Cov Ntsiab Lus: Qhov taw qhia tseem ceeb ntawm kev ua tau zoo
Sic yog cov nquag tivthaiv ntawm dub silicon carbide, thiab nws cov ntsiab lus ncaj qha cuam tshuam kev nyuaj, thiab thermal conductivity. Cov xwm txheej sib txawv muaj cov cai nruj me ntsis rau cov ntsiab lus sic:
- Abrasive kev lag luam:Siab - qib abreeives (piv txwv li, sib tsoo log, Sandpaper) xav tau cov ntsiab lus sic ntau dua los yog sib npaug rau 97%. Cov ntsiab lus tsawg (qis dua 90%) yuav ua rau muaj cov nyom ntawm cov av loj, txo kev sib tsoo ua kom zoo, thiab tsis xwm yeem ntawm cov haujlwm.
-} kev lag luam refractory:Refractory cib thiab cov khoom siv cas yuav tsum muaj cov ntsiab lus sic ntawm 85% thiab 95%. Tsis muaj zog yuav tsis muaj zog siab - kub kuj, ua rau kev ua ntej yug los ntawm cov refractories hauv kilns.
- semiconductor kev lag luam:Siab - Purity Dub silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic Silic
Kev sim cov qauv los xyuas cov ntsiab lus SIC:
{{0 {}}} titration:Txoj kev tseeb tshaj plaws rau kev sim ntau, haum rau kev kuaj sim ua pov thawj. Nws tuaj yeem kuaj cov ntsiab lus siic nrog qhov yuam kev ntawm tsawg dua lossis sib npaug rau 0.5%.
-} Spectral tsom xam:Sai ntawm -}}} qhov chaw xeem (tshwm sim hauv 10 feeb) rau cov khoom xa tuaj, tsim nyog rau kev txheeb xyuas batch sib xws.
{{0 {{}} thb -}} Tog ntawv pov thawj:Thov SGS, BV, lossis ISO 14611 tsab ntawv ceeb toom los ntawm cov chaw muag khoom kom ntseeg tau cov ntaub ntawv tseeb.
2. Cov pa roj carbon dawb: Lub zais dab neeg uas muaj kev puas tsuaj zoo
Cov neeg siv roj carbon pub dawb yog ib qho tsis paub tab hauv cov xim dub silicon carbide ntau lawm (muab tau los ntawm cov tshuaj tiv thaiv tsis tiav ntawm cov khoom siv raw). Cov pa roj carbon ntau dhau yuav ua rau muaj teeb meem loj:
-} Daim Ntawv Thov Abrasive:Cov pa roj carbon dawb yuav ua raws li cov av uas muaj cov tawv nqaij sib tsoo, txo kev sib tsoo tsoo thiab ua rau "txhaws" ntawm cov log sib tsoo.
-} Refractory Daim Ntawv Thov:Thaum kub siab, pub roj carbon dawb nrog oxygen los ua co, tsim cov hws hauv kev ua haujlwm thiab txo qis ntom ntom.
-} ib qho kev cuam tshuam ib puag ncig:Cov pa roj carbon ntau dhau heev ua rau muaj cov hmoov av ntau dua thaum ua, nce cov kev tiv thaiv ib puag ncig.
Cov Qauv Yuav Tsum Tau Txais Cov Roj Carbon Dawb:
{{0- tus nqi hwm (rau abrasives):Tsawg dua los yog sib npaug rau 0.5%
{{0- muaj qib muaj kev lag luam (rau refactories):Tsawg dua los yog sib npaug rau 1.0%
{{0- qis - cov khoom lag luam zoo:Feem ntau tshaj 2.0%, nrog pom cov hmoov dub dub thaum dej nag thaum muaj dej ntws.
Yooj yim rau -}} Cov ncauj lus mus kuaj:Siv cov qauv me me, tsau nws hauv dej huv, thiab do. Yog tias cov dej hloov dub thiab muaj qhov pom tseeb tom qab sawv, cov ntaub ntawv muaj cov pa roj carbon dawb yuav siab dhau.
Tus nqi - Kev Yuav Khoom Zoo: Tshuav Nyiaj Zoo Thiab Nqe
Kev yuav dub silicon carbide tsis yog hais txog "tus pheej yig dua" lossis "tus nqi tshaj plaws yog qhov zoo tshaj plaws". Tus yuam sij yog kom phim nrog daim ntawv thov kev xav tau thiab zam dhau lossis them tus nqi.
Cov kev siv sib txawv uas yuav tsum muaj cov ntsiab lus sib txawv rau cov ntsiab lus sic.
-}}}}}}} Yog siv rau kev sib tsoo cov pa roj carbon hlau, Si5% yog tsis tas yuav yuav 97% qib (uas yog 10% -15% kim dua).
- rau cov roj me me ntawm cov khoom muaj cov khoom siv me me, txuag tau 20% nqi ntxiv rau 90% qib.
Kev yuav dub silicon carbide yuav tsum muaj feem sib npaug thiab tus nqi. Tus tub ntxhais yog kom tsom rau cov ncauj lus sic thiab cov ntsiab lus roj carbon dawb}}} Cart Kev ntsuas cov khoom lag luam qis dua. Nyob rau tib lub sijhawm, los ntawm daim ntawv thov kom paub meej, xaiv cov neeg muag khoom, thiab ua kom zoo rau cov nqi logistics, koj tuaj yeem ua tiav tus nqi {}} kev yuav khoom.
Yog tias koj xav tau kev cai dub silicon carbide (ntau qhov sib txawv lossis thib peb {}}} zoo dub silicon carbide rau thoob ntiaj teb cov neeg yuav khoom. Peb muab ISO 9001 ntawv pov thawj thiab SGS kev ceeb toom rau txhua pob.Tiv Tauj PebNiaj hnub no rau cov qauv dawb thiab tso lus!
