Orgrasive kev lag luam (sib tsoo lub log, polishing hmoov)
3. High-purity alumina (99.9% -99. 999%)
• Nta: ultra-siab huv, qis impurities, rwb thaiv tsev hluav taws xob zoo heev
• Siv tau kev lag luam:
o coj & semiconductor (sapphire substrate, ntim ntim hluav taws xob hauv tshuab hluav taws xob)
o Lithium roj teeb (Diaphragm txheej, khoom electrolyte)
o Optical iav (Laser Crystal, pob tshab ceramic)
4. Tshwj xeeb alumina (hloov alumina)
• Nta: Tom qab kev kho mob saum npoo lossis doping, nws muaj cov haujlwm tshwj xeeb (xws li conduction, tshuaj tua kab mob)
• Siv tau kev lag luam:
o Tshuaj (tshuaj pab txhawb nqa cov cab kuj)
o Cov tub rog kev lag luam (infrared cov khoom siv)
o 3D luam ntawv (tej hub sib xyaw ua ke)
Kev lag luam sib txawv muaj cov kev xav tau sib txawv rau Alumina. Nov yog qee cov lus qhia rau ntau yam lag luam:
1. Petrochemical Kev Lag Luam
Cov tseev kom muaj: thaj chaw tshwj xeeb, kev siv zoo lub zog, kub tiv
• Cov khoom pom zoo kom cov khoom: Ua kom tiav alumina (-al₂o₃)
• Thov ua piv txwv:
o Catalyst tus cab kuj (hydrodesulfurization, hloov kho cov tshuaj tiv thaiv)
o Desiccant (Nrib pleb roj lub cev qhuav dej, ntuj ua kom huv)
2. Kev tiv thaiv ib puag ncig kev lag luam (Whastewaterater \/ khib nyiab roj)
• Xav tau: cov adsorption muaj zog, ua dua tshiab dua, tus nqi qis
• Pom cov khoom lag luam: Macroporous activated alumina
• Thov ua piv txwv:
o defluorination tus neeg sawv cev (haus dej haus huv)
o Vocs adsorption (kev lag luam khib kev kho)
3. Ceramics thiab Refractory Kev Lag Luam
• Xav tau cov kev ua kom siab kub, muaj qhov kub siab, qis shrinkage
• Pom cov khoom kom pom zoo: escined alumina (-al₂o₃)
• Thov ua piv txwv:
o hauv hluav taws xob ceramics (ua ke Cegrcuit Court afrate)
O Refractory cib (steel smelting rauv taws)
4. Kev lag luam hluav taws xob tshiab (roj teeb lithium, photovoltaic)
• Xav tau: ultra-siab purity, nano-particle loj, electrochemical ruaj khov
• Pom cov khoom lag luam pom zoo: kev siab dawb-Alumina (99.99% lossis ntau dua)
• Thov ua piv txwv:
o Lithium roj teeb cais txheej (txhim kho thermal stability)
o Khoom electrolyte (txhim kho ionic conductivity)
5. Kws ua tshuaj thiab kev lag luam khoom noj khoom haus
• Xav tau: Tsis muaj tshuaj lom, zoo biocompatibility, tswj tso tawm
• Pom cov khoom lag luam: Cov qib Tshuaj siab siab-purity alumina
• Thov ua piv txwv:
o Cov tshuaj muaj zog-tso cov cab kuj
o Khoom noj khoom haus ntxiv (tiv thaiv tus neeg sawv cev)
Xaiv lub alumina sab xis yuav tsum xav txog kev siv kev lag luam, cov khoom lag luam, nqi thiab lwm yam. Piv txwv li: Kev lag luam petrochemical nyiam cov alumina nrog thaj chaw tshwj xeeb; Txoj kev lag luam ceramic yuav tsum kub siab qhov kub tau rov qab kho Alumina; Kev lag luam hluav taws xob tshiab kev lag luam kev lag luam ntawm ultra-siab huv 99.99% alumina.
Los ntawm kev xaiv tshawb fawb, kev ua tau zoo ntawm alumina tuaj yeem ua kom tiav, kev ua tau zoo, ntau lawm tau txhim kho thiab cov nuj nqis tuaj yeem raug txo kom tsawg. Yog tias koj tsis paub yuav ua li cas xaiv, koj tuaj yeem tiv tauj peb kom paub meej qhov kev sib tw zoo tshaj plaws.
