Silicon carbide ceramic lined hnav-resistant yeeb nkab
Cov kav dej uas tiv taus silicon carbide yog cov kav dej uas ua los ntawm silicon carbide thiab muaj kev siv dav hauv ntau qhov chaw. Nws qhov kev sib tw tseem ceeb yog raws li nram no:
（1）Kev Hloov Pauv Lub Neej
Thaum thauj cov khoom siv abrasive xws li slurry thiab thee tshauv, lub neej ntev yog 10 npaug ntawm cov hlau, txo cov kev hloov pauv ntau zaus thiab kev poob sijhawm tsis ua haujlwm.
(2) Cov xwm txheej ua haujlwm hnyav heev yog thoob ntiaj teb
Kev ua haujlwm ruaj khov ntawm -50 ℃ txog 1600 ℃, nrog kev tiv thaiv thermal shock kom tiv thaiv kev tawg, tsim nyog rau cov xwm txheej kub siab xws li metallurgy thiab kev lag luam tshuaj lom neeg.
(3) Siv ntau yam khoom siv ib zaug
Tib lub sijhawm daws plaub qhov teeb meem loj ntawm kev hnav, xeb, kub siab, thiab kev tiv thaiv kev tawg.
(4) Lub teeb yuag thiab txuag hluav taws xob
Kev tsim qauv sib dua txo cov nqi thauj mus los thiab kev teeb tsa, thiab cov coefficient sib txhuam qis txo cov kev siv zog ntawm cov twj tso kua mis.
Qhov zoo ntawm cov kav dej silicon carbide piv rau cov ntaub ntawv ib txwm muaj:
| Kev ntsuas kev ua tau zoo | Cov kav dej silicon carbide | Cov kav hlau/yas |
| Kev hnav tsis kam | Hardness 2800HV (5 zaug ntawm hlau), lub neej ntev dua 10 zaug ntawm cov kav dej uas tsis yog hlau | Hlau yog ib qho yooj yim hnav thiab rhuav, thaum yas muaj qhov nyuaj tsawg (PE <1 HV) |
| Kub siab kev tiv thaiv | Tiv taus qhov kub siab ntawm 1600 ℃ thiab thermal shock (coefficient ntawm thermal expansion 4 × 10 ⁻⁶/℃) | Cov hlau tsis xeb yooj yim rau oxidation ntawm qhov kub siab, thaum cov yas muaj qhov kub tsis kam tsawg dua 80 ℃ |
| Kev tiv thaiv xeb | Tiv taus cov kua qaub muaj zog (concentrated sulfuric acid), cov hauv paus muaj zog, thiab cov hlau molten corrosion | Cov hlau tsis xeb muaj kev xeb thaum raug rau cov chloride ions, thaum cov yas muaj kev tiv thaiv tshuaj tsawg |
| Sib dua | Qhov ceev ntawm 3.0 ~ 3.14 g / cm ³ (60% sib dua li hlau) | Cov kav dej hlau loj heev thiab muaj cov nqi teeb tsa siab |
| Kev nthuav dav ntawm kev ua haujlwm | Tiv thaiv kev ua haujlwm zoo li qub (kev coj ua tsis muaj zog), kev huv ntawm qib semiconductor | Cov hlau xav tau kev kho mob ntxiv rau kev tiv thaiv kev tawg, thaum cov yas yooj yim raug kuab paug |
Hauv ntej, yuav luag tsis muaj lwm txoj kev daws teeb meem rau cov kav dej silicon carbide thaum thauj cov xov xwm uas muaj zog heev thiab hnav-resistant xws li acidic slurries thiab cov tshauv roj flue kub siab.
Yog tias koj muaj lus nug, thov koj xav tiv tauj peb txhua lub sijhawm.
Shandong Zhongpeng Special Ceramics Co., Ltd yog ib qho ntawm cov khoom siv tshiab silicon carbide ceramic loj tshaj plaws hauv Suav teb. SiC technical ceramic: Moh qhov nyuaj yog 9 (New Moh qhov nyuaj yog 13), nrog kev tiv thaiv zoo heev rau kev yaig thiab xeb, kev puas tsuaj zoo heev - kev tiv thaiv thiab kev tiv thaiv oxidation. SiC cov khoom lub neej kev pabcuam yog 4 txog 5 zaug ntev dua li 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 zaug ntawm SNBSC, nws tuaj yeem siv rau cov duab nyuaj dua. Cov txheej txheem hais nqe yog ceev, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob rau tsis muaj leej twg. Peb ib txwm mob siab rau kev sib tw peb lub hom phiaj thiab muab peb lub siab rov qab rau lub zej zog.
