Raws li lub ntsiab lus nruab nrab ntawm - mus rau - siab - kawg tiv thaiv - cov khoom siv hauv cov khoom siv hauv kev lag luam ceramic, nws ua rau qhov sib txawv ntawm qhov sib txawv ntawm 92% alumina ceramics thiab siab - nqi zirconia ceramics. Nws zoo hais txog cov ntsiab lus ntawm kev lag luam ntawm cov khoom siv nto abrasion, particle scouring, nruab nrab corrosion thiab cov khoom adhesion blockage. Daim ntawv no tshawb xyuas cov khoom siv microscopic, cov txiaj ntsig tseem ceeb ntawm kev ua tau zoo, kev sib tw sib txawv thiab cov txheej txheem kev lag luam ntawm 95 alumina ceramic nplooj ntawv, thiab sau cov ntsiab lus ntawm nws cov nqi engineering hauv tag nrho - kev tiv thaiv cov cuab yeej siv lub neej, muab cov txheej txheem kev siv rau kev lag luam los tiv thaiv- hnav kho dua tshiab thiab xaiv cov khoom siv kom zoo.
1.
Cov khoom siv thauj khoom ntau, thermal fais fab kev lag luam, thee chemical processing and mineral beneficiation industries are faced long-term composite damage to equipment in walls, including high-hardness particle cutting wear, cyclic material impact, humid medium corrosion and alternating thermal stress. Kev tiv thaiv ib txwm muaj xws li carbon steel, alloy steel, roj hmab thiab cam khwb cia basalt muaj cov cuab yeej cuab yeej cuab tam. Cov ntaub ntawv hlau raug kev txom nyem sai sai thiab perforation nyob rau hauv muaj zog scouring; cov roj hmab liners yog nquag mus rau kev laus, deformation thiab tev ntawm nruab nrab thiab siab kub; low-qib ceramics muaj xoob microstructure, tsis zoo compactness thiab tsis txaus cuam tshuam, tsis tuaj yeem hloov mus rau ntev -lub sij hawm tsis tu ncua hnyav-load ua hauj lwm tej yam kev mob.
Nrog kev txhim kho txuas ntxiv ntawm kev lag luam ntse thiab qis - carbon ntau lawm, cov lag luam muaj cov kev xav tau ntau dua rau cov khoom siv ua haujlwm ruaj khov, tsis tshua muaj txij nkawm thiab kev pabcuam ntev. Raws li ib qho kev hloov kho tshiab ntawm cov pa alumina ceramics, 95 alumina ceramic nplooj ntawv optimize siv lead ua qauv thiab sintering ntom, ua tiav kev sib tw hauv kev hnav tsis kam, kev ruaj ntseg thiab corrosion kuj. Nws tau maj mam dhau los ua tus nqi tshaj plaws - siv tau universal los tiv thaiv - cov ntaub ntawv hauv ob sab phlu rau kev ua haujlwm hnyav.
2. Microstructure thiab Intrinsic Material yam ntxwv
Qhov kev ua tau zoo tshaj ntawm 95 alumina ceramic los xij yog los ntawm nws qhov siab -purity crystalline qauv thiab siab - ntom sintering xeev. Tom qab siab -kub kua-theem sintering, cov ntaub ntawv tsim ib qho zoo thiab ntom -Al₂O₃ lis matrix, nrog qhib porosity ze rau xoom thiab dej nqus tsawg dua 0.05%. Piv nrog rau cov khoom siv alumina uas tsis muaj -purity alumina, nws tshem tawm cov pores me me thiab cov khoom tsis xws luag, txhim kho cov qauv kev ruaj ntseg thiab tiv thaiv kev muaj peev xwm nkag mus.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, 95 alumina ceramic ncav cuag Mohs hardness 9, thib ob tsuas yog pob zeb diamond ntawm cov khoom siv niaj hnub. Nws hnav tsis kam yog 20-30 npaug ntawm cov pa roj carbon zoo tib yam thiab 5-8 zaug siab dua 92% alumina ceramics. Lub siab tawv siv lead ua lattice qauv ua rau nws tiv thaiv kev txiav tsis tu ncua thiab scouring ntawm siab -hardness impurities xws li quartz, gangue thiab ntxhia hmoov yam tsis muaj qhov qaug zog hnav.
Chemically, cov ntaub ntawv exhibits heev inertness. Nws tuaj yeem tiv taus ntev - lub sij hawm yaig ntawm acidic coal slurry, sulfide nruab nrab, alkaline tshauv dej thiab muaj ntsev tov, tsis muaj tshuaj tiv thaiv, dissolution los yog deterioration. Nyob rau hauv cov nqe lus ntawm thermal kev ua tau zoo, nws tuav ruaj khov lub cev nyob rau hauv 0-1000 degree, nrog tsawg thermal expansion coefficient thiab zoo heev thermal poob siab kuj, tsis txhob tawg thiab tev tawm los ntawm ib tug heev txias thiab kub alternation.
Tsis tas li ntawd, daim iav - du sintered nto zoo heev txo qhov kev sib txhuam coefficient, zoo inhibiting adhesion thiab hardening ntawm ntub dej nplua coal hmoov, slurry thiab viscous cov ntaub ntawv, daws cov teeb meem ntev blockage ntawm industrial conveying khoom.
3. Core Engineering Advantages thiab Differentiated Competitiveness
Sib txawv ntawm ib qho -cov ntaub ntawv txhim kho kev ua tau zoo, 95 alumina ceramic sheets muaj cov txheej txheem tag nrho - lifecycle engineering zoo, ntsuas kev ua haujlwm ruaj khov, kev tsim kho yooj yim thiab kev lag luam.
Nws ua tiav ultra- lub neej ua haujlwm ntev thiab tus nqi saib xyuas qis. Raws li tus qauv hnyav kev lag luam ua haujlwm, lub neej kev pab cuam ntawm 95 alumina hauv ob sab phlu tuaj yeem ncav cuag 5-8 xyoo, deb tshaj 3-6 lub hlis ntawm cov hlau phaj thiab 1-2 xyoo ntawm cov roj hmab liners. Its dense structure avoids medium penetration and internal corrosion, and local damaged sheets can be replaced independently without overall pipeline disassembly, greatly reducing maintenance downtime and labor cost.
Nws sib npaug hnav tsis kam thiab cov qauv kev hloov pauv. Piv nrog nkig qis- qib ceramics, optimized grain grading thiab siab -density sintering endow 95 alumina sheets with better toughness and compression resistance, adapting to not only pa scouring surfaces but also medium- impact positions such as chute turning point and hopper buff . Lub caij no, daim ntawv- hom qauv tsim txhawb nqa ntawm - qhov chaw txiav thiab tso, haum rau cov kab nkhaus nyuaj, lub luj tshib thiab cov khoom tshwj xeeb- zoo li cov khoom siv uas cov kav dej ceramic tsis tuaj yeem hloov mus.
Nws muab lub zog zoo tshaj plaws -txuag thiab ntws- ua kom ruaj khov. Lub ultra- sab hauv phab ntsa du txo cov khoom siv thauj khoom, txo qis kev ua haujlwm ntawm cov kiv cua thiab cov twj slurry, thiab txo cov kev siv hluav taws xob zoo. Tsis muaj cov khoom adhesion thiab scaling ua kom ruaj khov thiab cov khoom zoo ib yam, tsis txhob muaj kev hloov pauv los ntawm cov kav dej thaiv thiab arching.
Nws muaj ib puag ncig zoo thiab tiv thaiv - tus nqi pa phem. Cov khoom siv ceramic tsis yog - tshuaj lom thiab tshuaj lom neeg ruaj khov, yuav tsis poob ntawm cov hlau impurities kom ua paug cov ntaub ntawv raw, thiab tshwj xeeb tshaj yog haum rau siab - purity ntxhia thiab cov khoom siv hluav taws xob tshiab. Nws kuj tseem tshem tawm cov khoom xau thiab ib puag ncig muaj kuab paug los ntawm cov khoom siv perforation.
4. Tej yam kev lag luam daim ntawv thov scenarios
95 alumina ceramic los xij muaj qhov hloov tau dav thiab dav siv hauv hnyav-cov haujlwm tiv thaiv- hnav thiab tiv thaiv- cov xwm txheej corrosion hauv ntau yam lag luam.
Hauv kev lag luam thermal fais fab, nws yog cov khoom siv tseem ceeb hauv cov khoom siv rau cov coal conveying chutes, tshauv tawm pipelines, hmoov separators, desulfurization thiab denitrification cov cuab yeej, daws cov abrasion thiab corrosion teeb meem tshwm sim los ntawm ya tshauv, slag thiab flue roj nruab nrab.
Hauv cov thee mining thiab thee chemical industries, nws yog siv rau hauv cov thee bunkers, hloov chutes, raw thee ntxuav pipelines thiab gangue conveying systems, tiv thaiv ntub coal adhesion thiab gangue particle cuam tshuam.
Nyob rau hauv metallurgy thiab ntxhia ua, nws kab hlau ore, quartz ore thiab tailings conveying cov cuab yeej, zoo tiv nrog ntev - lub sij hawm siab - lub zog scouring ntawm siab - hardness ntxhia hais thiab txhim kho cov kev ua haujlwm tas li ntawm cov txiaj ntsig zoo.
Hauv cov cement, cov ntaub ntawv hauv tsev thiab tshuaj lom neeg kev lag luam, nws yog siv rau cov hmoov nplej nyoos hmoov conveying, clinker chute thiab corrosive hmoov ua cov cuab yeej, txo cov cuab yeej tsis ua hauj lwm thiab ncua kev txij nkawm.
5. Kev xaus thiab kev lag luam Prospect
95 alumina ceramic daim ntawv sawv cev rau tus nqi tshaj plaws - siv tau siab - qauv kev teeb tsa hauv kev lag luam coj los siv - cov ceramics resistant. Nws zoo kawg nkaus ua ke nrog kev ua haujlwm siab hardness hnav tsis kam, tshuaj tiv thaiv corrosion, thermal stability thiab saj zawg zog kev ua tau zoo, ua rau kev ua haujlwm tsis zoo ntawm cov hlau, roj hmab thiab qis - qib ceramic liner. Txawm hais tias thawj zaug peev yog siab dua li cov ntaub ntawv ib txwm siv, nws ultra- lub neej ua haujlwm ntev, kev saib xyuas tsis zoo thiab lub zog- txuag tau zoo heev txo cov nqi ua haujlwm ntawm cov lag luam thoob plaws hauv lub neej.
Raws li kev lag luam hnyav txuas ntxiv txhawb kev hloov pauv kev txawj ntse, kev txuag hluav taws xob thiab kev tsim ntsuab, kev ua haujlwm siab -cov khoom siv hauv cov khoom siv ceramic yuav maj mam hloov cov ntaub ntawv hauv ob sab phlu. Nrog kev ua haujlwm ruaj khov, kev hloov pauv dav dav thiab cov txiaj ntsig zoo ntawm kev lag luam, 95 alumina ceramic los xij yuav nyob twj ywm qhov kev nyiam thoob ntiaj teb los tiv thaiv - coj kev daws teeb meem rau cov cuab yeej siv khoom lag luam, muab kev txhawb nqa kev ntseeg siab rau kev nyab xeeb, ua haujlwm tau zoo thiab qis dua - carbon ua haujlwm ntawm cov khoom siv niaj hnub thauj khoom.
