Taw qhia
Honeycomb ceramics yog hom tshiab ntawm cov khoom siv ua haujlwm ceramic uas muaj cov qauv ntxeem tau zoo li niaj zaus. Lawv feem ntau yog tsim los ntawm raw cov ntaub ntawv xws li silicon carbide (SiC), cordierite (Mg₂Al₄Si₅O₁₈), thiab mullite (3Al₂O₃·2SiO₂) los ntawm extrusion molding thiab high-temperature sintering.
Tsim los khaws thiab tso tawm thermal zog, honeycomb ceramics tau siv dav hauv kev txuag hluav taws xob rau cov khoom siv thermal. Lawv cov qauv yooj yim muaj ntau qhov pores me me uas muaj nyob rau hauv hexagonal lossis square qauv, ua rau cov honeycomb lattice. Qhov kev tsim no txhim kho thaj chaw saum npoo, txhim kho thermal conductivity, thiab ua kom muaj cua sov nqus thiab tso tawm, yog li muab cov cua sov ruaj khov thiab kav ntev.
Qhov zoo
Thermal Performance: Paradoxical Unity ntawm High-Efficiency Thaum tshav kub kub cia thiab rwb thaiv tsev
Ultra-Efficient Thaum tshav kub kub Exchange Capacity:Lub qhov hws ntom ntom tsim cov nyhuv "kub daim txhuam cev", ua rau muaj kev kub ntxhov ntawm cov pa hluav taws kub kub thiab cua hauv qhov pores. Qhov no txo cov sij hawm sib pauv cua sov los ntawm 5 vib nas this (nrog ib txwm checker cib) kom tsawg dua 1 thib ob.
Qhov ntxeem tau ntawm honeycomb qauv muab honeycomb ceramics ib thaj tsam ntawm 100-500 m² / m³ (ib txwm refractory cib tsuas muaj 1-10 m² / m³). Piv txwv li, nyob rau hauv ib tug steel reheating rauv, siv cordierite honeycomb ceramics nce flue roj pov tseg thaum tshav kub kub rov qab efficiency ntawm 60% mus rau ntau tshaj 90%, txo roj noj los ntawm 30%, thiab ua tiav txhua xyoo txuag hluav taws xob sib npaug rau 2,000 tons ntawm cov qauv thee.
Qhov sib npaug ntawm cov thermal conductivity tsawg thiab thermal poob siab kuj
Honeycomb ceramics muaj thermal conductivity ntawm tsuas yog 0.2-1.0 W / (m·K) (high-alumina cib muaj 1.5-3.0 W / (m·K)), uas tuaj yeem txo qhov kub ntawm cov phab ntsa sab nraud los ntawm 50-80℃thiab kub poob los ntawm 15-20%. Lub caij no, cov qauv ntxeem tau ua raws li "kev poob siab absorber" kom dissipate thermal stress. Cordierite-raws li honeycomb ceramics tuaj yeem tiv taus thermal shock ntawm 800℃(tsuas yog refractory cib tsuas yog 300-500 degree), ua rau lawv tsis tshua muaj kev tawg thaum lub khob cij pib-nres.
Erosion Resistance: Innovative Corrosion Resistance nyob rau hauv ntau yam scenarios
Muaj zog tiv taus hlau thiab iav Melts
Nyob rau hauv txhuas alloy casting, SiC honeycomb tej hub lim ntes inclusions loj tshaj 50 μm, txo casting impurity ntsiab lus los ntawm 0.3% mus rau hauv qab 0.05%. Lawv kuj nthuav tawm qhov hnav qis dua 0.1 hli rau 1000 lub voj voog hauv qab 1100℃aluminium melt scouring (piv rau 0.5 mm / 1000 cycles rau cov tsoos quartz xuab zeb lim).
Hauv iav kilns, mullite-based honeycomb ceramics qhia plaub zaug muaj zog tiv thaiv Na₂O thiab lwm yam oxide yaig dua li av nplaum cib. Lawv lub neej kev pab cuam nyob rau hauv 1600℃iav melt volatile ib puag ncig mus txog tsib xyoos (ib txwm refractory bricks tsuas yog ob xyoos).
Adaptability rau Complex Atmospheres
Nyob rau hauv khib nyiab incinerators, SiC honeycomb ceramics tiv taus corrosion los ntawm acidic gases (xws li, HCl, SO₂) nyob rau hauv 850℃+ flue gas thaum preheating combustion cua kom siab tshaj 800 degree, txhawb dioxin decomposition tus nqi siab tshaj 99.9%.
Qhov zoo ntawm cov qauv: Subversive breakthrough nyob rau hauv lub teeb yuag thiab siab zog
Ob chav Optimization ntawm ntim thiab qhov hnyav
Nrog lub porosity ntawm 70-90%, honeycomb ceramics txo qhov ntim los ntawm 50% thiab hnyav los ntawm 30% piv rau cov tsoos refractory cib nyob rau hauv tib lub tshav kub cia peev.
Scratch Resistance thiab Kev Pabcuam Ntev
Lub pore phab ntsa ntawm honeycomb ceramics yog du (roughness Ra < 5 μm), nrog rau hnav tus nqi tsawg dua 0.05 mm / xyoo nyob rau hauv high-temperature flue gas scouring (ntws tus nqi 15-20 m / s) - qhov tseem ceeb qis dua cov tsoos refractory cib (0.2 mm / xyoo).
Ntsuab thiab txuag hluav taws xob: Cov khoom siv tseem ceeb rau kev txo cov pa roj carbon monoxide hauv kev lag luam kilns
Honeycomb ceramic tshav kub cia tshuab txhim khu cov thermal efficiency ntawm 25-35%. Cov khoom siv honeycomb ceramics tuaj yeem raug crushed thiab rov siv dua li cov khoom siv tshiab, nrog cov nqi rov qab mus txog 90% rau SiC-raws li thiab 70% rau cov khoom siv cordierite. Qhov no txo qis cov khoom pov tseg emissions piv rau cov tsoos refractory bricks (rov qab tus nqi tsawg dua 30%).
Catalytic-Thermal Storage Integration
Hauv kev kho cov roj av ceramic, TiO₂-loaded honeycomb ceramics ua rau tib lub sijhawm pov tseg thaum tshav kub kub rov qab (preheating cua mus rau 300 degree) thiab catalytic VOC degradation (efficiency tshaj 95%), txo cov cuab yeej siv peev los ntawm 40%.
