Silicon carbide ceramic lined hnav-resistant yeeb nkab thiab hydrocyclone nyob rau hauv fais fab nroj tsuag
Silicon Carbide Ceramic Piping Systems: Reinventing Power Plant Infrastructure
Cov chaw tsim hluav taws xob tau ntsib cov teeb meem kev ua haujlwm hnyav, nrog cov kav dej kav ntev:
-Nruam thermal cycling (100-650 ° C)
- Abrasive particle tshaj tawm tshaj 30 m / s
- pH variations ntawm 2-12 hauv flue gas scrubbers
- Cyclic siab hloov pauv (0-6 MPa)
Ib txwm siv hlau thiab cov kav dej polymer feem ntau ua tsis tau raws li cov xwm txheej no, ua rau silicon carbide (SiC) ceramic hnav-resistant kav cov kev daws teeb meem rau niaj hnub fais fab nroj tsuag.
Material Science Breakthrough
SiC ceramic kav muab cov khoom tshwj xeeb tseem ceeb rau kev siv hluav taws xob ua haujlwm:
- Vickers Hardness 28 GPa (4 × nyuaj dua tungsten carbide)
- Hnav tus nqi <0.1 mm³ / N·m (ASTM G65)
- Thermal conductivity 120 W / m·K (zoo tshaj rau stainless hlau)
- Chemical Inertness (tiv taus 98% H₂SO₄ ntawm 300 ° C)
Kev ua haujlwm zoo hauv cov txheej txheem tseem ceeb
1. Coal tuav & tshauv thauj
- Nrog 5-7 hli / xyoo erosive hnav los ntawm 60% cov ntsiab lus slurry
- Khaws <5% ntws txo ntau dua 10,000 teev ua haujlwm
2. Flue Gas Desulfurization (FGD)
- pH-resistant kev ua tau zoo nyob rau hauv limestone slurry circuits
- Tshem tawm chloride-induced pitting corrosion
3. Fly Ash Conveyance
- 0.08 μm nto roughness minimizes particle adhesion
- Kov 50 tph muaj peev xwm ntawm 35 ° inclination ces kaum
Kev hloov pauv nyiaj txiag
Cov neeg cog qoob loo qhia txog cov txiaj ntsig ntsuas tau:
- 70% txo qis hauv kev hloov cov yeeb nkab uas tsis tau npaj tseg
- 55% txo tus nqi ua haujlwm ua haujlwm
- 18% txhim kho thermal efficiency hauv chav voj voog
- 40% ncua qhov system lifespan vs. alloy lwm txoj
Installation & Kev Ua Haujlwm Flexibility
- Modular 1-6 m seem nrog flanged / xov txuas
- 60% yuag poob vs. steel sib npaug (3.2 g / cm³ ceev)
- Retrofittable rau cov yeeb nkab uas twb muaj lawm txhawb nqa thiab hangers
- Tau tshaj nrog cov kev soj ntsuam ntse rau kev coj ua kwv yees
Yav tom ntej-Focused Innovations
Tom ntej tsab xov xwm SiC piping solutions integrate:
- Gradient porosity rau thermal mitigation
- Conductive variants rau electrostatic nag lossis daus
- Hybrid ceramic-elastomer pob qij txha rau kev co damping
- Tus kheej tu nto nano-textures
Los ntawm cov chaw tsim hluav taws xob hluav taws xob mus rau cov chaw pov tseg-rau-zog, cov kav dej silicon carbide ceramic redefine kev ntseeg siab hauv cov khoom siv hluav taws xob. Lawv qhov tshwj xeeb ua ke ntawm kev ua haujlwm tsis muaj zog, thermal endurance, thiab tshuaj lom neeg ruaj khov ua kom muaj kev ua haujlwm tsis tu ncua nyob rau hauv cov xwm txheej hnyav - hloov cov sijhawm txij nkawm los ntawm kev kho reactive rau kev npaj, kev hloov kho kom zoo.
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.
