Hnav Resistant Silicon carbide ceramic yeeb nkab
Silicon carbide ceramic: Moh lub hardness yog 9.0 ~ 9.2, nrog zoo heev tiv taus yaig thiab corrosion, zoo heev puas-ua hauj thiab tiv thaiv oxidation. Nws yog 4 mus rau 5 npaug zog dua nitride bonded silicon carbide. Lub neej kev pabcuam yog 7 mus rau 10 npaug ntev dua li cov khoom siv alumina. MOR ntawm RBSiC yog 5 txog 7 npaug ntawm SNBSC, nws tuaj yeem siv rau cov duab ntau dua.
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 hnav tsis kam qhov chaw yog dav siv nyob rau hauv mining, ore crushing, tshuaj ntsuam thiab thauj ntawm siab coj, siab corrosive kua, kuj zoo heev haum rau txhua yam khoom nrog high precision thiab sealing yam yuav tsum tau hnav, thiab lwm yam. Material.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 cov kev pab cuam lub neej yog ntau tshaj 6 npaug ntawm polyurethane. silicon carbide hnav tsis kam ceramic cov khoom lag luam, hardness thib ob tsuas yog pob zeb diamond, nrog siab hnav tsis kam, kev ua haujlwm ntev lub neej nta.Qhov hnav tsis kam cov yeeb nkab thiab lub luj tshib uas ua nrog silicon carbide hnav tsis kam hauv ob sab phlu, nws cov ceramic hauv ob sab phlu thickness yog 6-35mm, cov qauv yog los nruab cov twb sintered ceramic raj rau hauv cov khoom siv caliber kua nplaum hauv nruab nrab cov yeeb nkab, nrog rau cov khoom siv 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 resistant peformance, cov khoom zoo ntawm qhov kub thiab txias, zoo erosion 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 cov ntaub ntawv nyob deb tshaj cov pobzeb thiab cov hlau nplaum. 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 tau siv ntau dua rau kev ua haujlwm nrog kev hnav ntawm qhov kub qis 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
- Thaum tshav kub kub exchangers
- Semiconductor wafer ua khoom siv
Metallurgy thiab fais fab kev lag luam: Qhov laj thawj yog 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 qhov loj tshaj plaws silicon carbide ceramic cov ntaub ntawv tshiab daws teeb meem 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.
