Silicon carbide hnav tsis kam, nws yog tsim los ntawm silicon carbide thiab carbon ntawm qhov kub thiab txias, belongs rau ib yam ntawm silicon carbide khoom.Lub silicon carbide coj kuj qhov chaw yog dav siv nyob rau hauv mining, ore crushing, tshuaj ntsuam thiab thauj ntawm siab coj, siab corrosive. Cov kua dej, kuj tsim nyog rau cov khoom siv kho tshuab nrog kev ua haujlwm siab thiab kev sib khi, xws li lub twj tso kua mis siab, lub twj tso kua mis sib nqus thiab lwm yam.Yog ib yam tshiab ntawm cov khoom siv tiv thaiv.Reaction-bonded silicon carbide hnav tsis kam bushing muaj cov yam ntxwv ntawm siab hardness, siab. hnav tsis kam, cuam tshuam tsis kam, kub tsis kam, acid thiab alkali corrosion kuj thiab lwm yam, thiab lub neej kev pab cuam tiag tiag yog ntau tshaj 6 npaug ntawm polyurethane. Cov ntaub ntawv ntxhib-grained, tau ua tiav hauv ntau lub mines.Our lub tuam txhab yog cov kws tshaj lij silicon carbide hnav tsis kam ceramic cov khoom lag luam, hardness thib ob tsuas yog pob zeb diamond, nrog rau siab hnav tsis kam, kev pab lub neej ntev. nrog silicon carbide hnav tsis kam hauv ob sab phlu, nws cov ceramic hauv ob sab phlu thickness yog 6-35mm, cov qauv yog rau nruab cov twb sintered ceramic raj rau hauv cov caliber steel raj, nrog cov kua nplaum nyob rau hauv nruab nrab. Hnav kuj ceramic kav muaj cov nram qab no zog piv nrog. yav dhau los saws cam khwb cia-pob zeb kav, hnav-resistant alloy cam khwb cia steel kav thiab ceramic puas kav.
Cov tshuaj tiv thaiv kev sib raug zoo silicon carbide (RBSC) muaj kev hnav zoo heev tiv taus peformance, cov khoom zoo ntawm qhov kub siab, zoo yaig thiab abrasive tsis kam, cov khoom no tuaj yeem siv rau ntau yam kev siv xws li yeeb nkab liner, ceramic luj tshib, tshuaj tsuag nozzles, txhaj tshuaj blast nozzles thiab hydrocyclone Cheebtsam.
ZPC linings deb tshaj cov pobzeb thiab hlau liners. ZPC silicon carbide ceramics yog thermal shock kuj thiab puas resistant uas ua rau ncua sij hawm khiav thiab txo downtime.
Cov tshuaj tiv thaiv kev sib raug zoo silicion carbide ceramic (RBSIC) yog ib qho zoo tagnrho hnav cov khoom siv tiv thaiv, tshwj xeeb tshaj yog tsim rau lub zog abrasive, ntxhib hais, kev faib tawm, concentration, lub cev qhuav dej thiab lwm yam haujlwm. Vim cov khoom saum toj no, lubRBSiC / SiSiC silicon carbide liner luj tshib / liner rajtuaj yeem tiv thaiv qhov zoo ntawm qhov hnav thiab kub kom ntev lub neej kev pab cuam ntawm cov khoom siv.

Kev ua haujlwm ntawm silicon carbide ceramic hnav-resistant yeeb nkab
Cov yam ntxwv ntawm silicon carbide muaj xws li:
- Tsawg ceev
- Siab zog
- Zoo kub siab zog (Reaction bonded)
- Oxidation kuj (Reaction bonded)
- Zoo heev thermal shock kuj
- High hardness thiab hnav tsis kam
- Cov tshuaj tiv thaiv zoo heev
- Tsawg thermal expansion thiab siab thermal conductivity
Tej yam silicon carbide daim ntaub ntawv muaj xws li:
Lawv siv ntau dua rau kev ua haujlwm nrog hnav ntawm qhov kub thiab txias dua li kev coj tus cwj pwm kub. SiC daim ntaub ntawv yog xws li sandblasting injectors, automotive dej twj tso kua mis seals, bearings, twj tso kua mis Cheebtsam, thiab extrusion tuag uas siv siab hardness, abrasion kuj, thiab corrosion kuj ntawm carbide ntawm silicon.
- Tsau thiab txav turbine Cheebtsam
- Seals, bearings, twj tso kua mis vanes
- Pob valve qhov chaw
- Hnav daim hlau
- Kiln rooj tog
- Kub exchangers
- Semiconductor wafer ua khoom siv
Kev lag luam metallurgy thiab fais fab kev lag luam: vim li cas vim li cas ob qhov kev lag luam no tau muab tso ua ke yog qhov tseem ceeb vim tias ob lub lag luam muaj kev lag luam.
Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd yog ib qho ntawm cov loj tshaj plaws silicon carbide ceramic cov khoom siv tshiab hauv Suav teb. SiC technical ceramic: Moh lub hardness yog 9 (New Moh's hardness yog 13), nrog zoo heev tiv taus yaig thiab corrosion, zoo heev abrasion - kuj thiab anti-oxidation. SiC khoom lub neej kev pab cuam yog 4 mus rau 5 zaug ntev dua 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 npaug ntawm SNBSC, nws tuaj yeem siv rau cov duab ntau dua. Cov txheej txheem hais tau nrawm, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob. Peb ib txwm pheej sim sim peb lub hom phiaj thiab muab peb lub siab rov qab los rau zej zog.
