1. Nyob rau hauv tej khoom conveying, thermal ua, ntxhia ua thiab tshuaj industries, muaj cov khoom siv nto tsis tu ncua fim loj particle scouring, abrasive hnav, tshuaj corrosion thiab kub alternation. Ib txwm hnav- cov ntaub ntawv tiv taus xws li hlau alloy, roj hmab thiab qis- qib ceramics feem ntau ua tsis tiav, ua rau cov khoom siv thinning, perforation, cov khoom to, nquag kaw thiab cov nqi kho mob siab. Nrog rau qhov yuav tsum tau nruj zuj zus ntxiv rau cov khoom siv ruaj khov, txuag hluav taws xob thiab tus nqi qis qis, kev hnav zoo tib yam - cov ntaub ntawv tiv thaiv tsis tuaj yeem ua tau ntev - lub sij hawm siab - load ua hauj lwm tej yam kev mob. Raws li qib siab-kawg hloov kho tshiab ntawm alumina ceramic cov ntaub ntawv, 95 alumina ceramic ntawv tau dhau los ua cov txheej txheem kev nyiam rau siab -txheej txheem kev lag luam los tiv thaiv- hnav kho dua tshiab vim nws cov compact microstructure, ruaj khov siv lead ua theem thiab kev ua haujlwm zoo.
2. Cov khoom siv tseem ceeb ntawm 95 Alumina Ceramic Sheet
Qhov kev ua tau zoo ntawm 95 alumina ceramic ntawv yog los ntawm nws qhov siab - purity -Al₂O₃ siv lead ua qauv thiab ze rau - puv - ntom ntom sintered lub xeev. Nws cov txheej txheem sab hauv yog sib xws, nrog qhib porosity ze rau xoom, ua kom tuab, tawv thiab ruaj khov ceramic matrix.
Ua ntej, nws muaj qhov nyuaj hardness thiab superior hnav tsis kam. Nrog Mohs hardness mus txog qib 9 thiab ultra- tsis tshua muaj kev puas tsuaj, nws hnav tsis kam yog 20-30 npaug siab dua carbon steel thiab deb tshaj 92% alumina ceramics. Nws tuaj yeem tiv taus ntev - lub sij hawm txiav thiab cuam tshuam los ntawm coal gangue, ore particles, ya tshauv thiab abrasive hmoov.
Qhov thib ob, nws muaj cov tshuaj lom neeg inertness zoo heev. Qhov ruaj khov alumina siv lead ua theem tiv taus acid corrosion, alkali yaig thiab ntsev nruab nrab kev laus, thiab yuav tsis hnov mob nrog sulfur - muaj cov thee slurry, cov dej khib nyiab thiab tshuaj lom neeg flue gas. Nws tswj kev ua haujlwm ruaj khov hauv cov av noo, corrosive thiab plua plav chaw ua haujlwm.
Thib peb, nws muaj thermal stability zoo heev thiab tsis tshua muaj thermal expansion . 95 alumina los xij tuaj yeem tiv taus ntev -lub sij hawm kub siab txog 1000 degree, muaj zog thermal shock tiv thaiv tsis tshua muaj txias thiab kub alternation. Nws yuav tsis deform, tawg los yog tev nyob rau hauv industrial kub fluctuation.
Tsis tas li ntawd, nws cov ultra- du nto zoo heev txo cov khoom adhesion, zoo daws cov khoom thaiv thiab phab ntsa- dai teeb meem uas feem ntau pom nyob rau hauv cov thee tuav thiab hmoov conveying tshuab.
3. Engineering Advantages thiab Industrial Value
Piv nrog rau cov tsoos hnav- cov ntaub ntawv tiv taus, 95 alumina ceramic los xij qhia pom tseeb tag nrho - lub neej zoo. Nyob rau hauv cov nqe lus ntawm kev pab cuam lub neej, nws ruaj khov lub cev muaj zog ua kom tsis tu ncua kev ua hauj lwm rau 5-10 xyoo nyob rau hauv cov kev ua hauj lwm hnyav, tag nrho hloov lub sij hawm hloov lub voj voog ntawm hlau thiab roj hmab liner. Nws zoo heev txo cov sij hawm tsis tau npaj tseg thiab txhim kho tag nrho cov cuab yeej ua haujlwm tus nqi.
Hais txog kev ua haujlwm ruaj khov, qhov siab - qhov ntom ntom tsis yog- cov qauv ntxeem tau zam kev nkag mus rau nruab nrab, degumming tsis ua haujlwm thiab muaj kev pheej hmoo ntawm tev hauv zos. Piv nrog rau qis-purity ceramic sheets, 95- cov khoom qib muaj tsawg dua qhov tsis xws luag, cov qauv tsim muaj zog dua thiab muaj zog tiv taus, haum rau hnyav-load thiab hnyav scouring txoj hauj lwm xws li hopper cuam tshuam nto, yeeb nkab luj tshib thiab chute tig seem.
Kev lag luam, txawm hais tias thawj zaug peev yog me ntsis siab dua li cov ntaub ntawv zoo tib yam, nws ultra- lub neej ua haujlwm ntev thiab kev saib xyuas- cov yam ntxwv dawb txo qis tom qab ua haujlwm thiab cov nqi khoom siv. Tus nqi tag nrho yog txo los ntawm ntau dua 50% thoob plaws hauv lub neej ntawm cov cuab yeej siv, ua tiav cov nqi siab tiag tiag -kev ua tau zoo.
Tsis tas li ntawd, lub teeb yuag ceramic daim ntawv yuav tsis ua rau muaj kev thauj khoom ntau dhau ntawm cov qauv hlau, thiab txhawb kev txiav yooj yim thiab ntawm - qhov chaw nteg, yoog rau cov khoom siv nyuaj uas tsis muaj kev hnav - cov ntaub ntawv tiv thaiv tsis tuaj yeem npog.
4. Cov ntawv thov kev lag luam
95 alumina ceramic los xij yog dav siv nyob rau hauv siab -tus qauv tiv thaiv- coj cov xwm txheej thoob plaws kev lag luam. Nyob rau hauv thermal fais fab nroj tsuag, lawv yog siv nyob rau hauv thee hoppers, tshauv chutes, hmoov concentrators thiab flue gas desulfurization khoom los daws cov tshauv abrasion thiab corrosion teeb meem. Hauv kev lag luam thee thiab thee chemical industries, lawv kab cov phab ntsa ntawm cov bunker, hloov cov chutes thiab slurry pipelines los tiv thaiv cov coal adhesion ntub thiab gangue cuam tshuam hnav.
Nyob rau hauv metallurgy thiab ntxhia ua, cov nplooj ntawv pab cov hlau ore hmoov conveying tshuab, tailings chutes thiab sintering khoom, muab ruaj khov los tiv thaiv - hnav tiv thaiv rau siab - hardness ntxhia hais. Hauv cov cement, cov ntaub ntawv hauv tsev thiab tshuaj lom neeg kev lag luam, lawv tau siv rau cov khoom siv raw khoom siv thiab cov hmoov ua cov hmoov corrosive, txhim kho cov khoom txuas ntxiv thiab txo cov khoom siv tsis ua haujlwm.
5.
95 alumina ceramic daim ntawv sawv cev rau cov paub tab thiab siab - theem kev ua tau zoo ntawm alumina hnav tam sim no - cov ntaub ntawv ceramic resistant. Nrog rau ultra-siab hardness, zoo heev hnav tsis kam, muaj zog corrosion kuj thiab ruaj khov thermal kev ua tau zoo, nws muaj txiaj ntsig zoo daws qhov ntev - sawv ntsug cov ntsiab lus ntawm cov khoom siv hnav, thaiv thiab ua haujlwm luv luv. Nyob rau hauv cov ntsiab lus ntawm kev txhim kho kev lag luam, kev txuag hluav taws xob thiab kev txhim kho kev nyab xeeb, 95 alumina ceramic los xij tau maj mam hloov cov tsoos hnav-cov ntaub ntawv tiv taus thiab dhau los ua cov ntsiab lus siab- tus qauv tiv thaiv-cov ntaub hauv ob sab phlu rau hnyav- cov khoom siv ua haujlwm, xa cov txiaj ntsig tseem ceeb ntawm kev lag luam thiab kev lag luam ntev - lub sijhawm ua lag luam.
