Alumina Ceramic Rollers: Cov Kev Siv Ntau Yam Uas Ua Rau Muaj Zog Rau Kev Ua Haujlwm Zoo Hauv Kev Lag Luam Kub Siab

Hauv kev tsim khoom kub siab, qhov xav tau cov khoom siv ruaj khov thiab txhim khu kev qha yog tas li.Alumina ceramic rollerssawv tawm, siv cov khoom zoo tshaj plaws los txhawb kev ua haujlwm zoo thoob plaws hauv kev lag luam - los ntawm kev ua kom iav sov mus rau kev tsim khoom semiconductor. Cov khoom siv khov kho no txhais tau dua qhov kev ua tau zoo hauv qhov chaw ib puag ncig hnyav. Cia peb tshawb nrhiav lawv cov ntawv thov tseem ceeb uas ua rau lawv tsis tseem ceeb rau kev tsim khoom niaj hnub no.
1. Daim Ntawv Thov Tseem Ceeb: Cov Kilns Tsim Khoom Siv Ceramic & Iav

Cov lag luam ceramic thiab iav yog cov neeg siv tseem ceeb, qhov twg cov menyuam no ua lub hauv paus ntawm cov txheej txheem roller kiln. Hauv cov vuas ceramic, cov khoom siv huv, thiab cov khoom siv porcelain, lawv xa cov khoom los ntawm kev kub hnyiab (txog li 1400 ° C +). Lawv lub zog kub siab thiab kev nthuav dav thermal qis tiv thaiv kev hloov pauv thiab cov khoom warping, kom ntseeg tau tias cov khoom zoo sib xws.

Rau kev tsim iav (tempering, annealing, melting), alumina ceramic rollers zoo heev hauv qhov chaw ua kom sov. Tsis zoo li lwm txoj hauv kev hlau, lawv tiv taus kev xeb iav molten thiab tswj qhov ruaj khov, ua rau kev thauj mus los ntawm daim ntawv iav du yam tsis muaj kuab paug - qhov tseem ceeb rau kev tsim kho vaj tse thiab kho qhov muag iav, txhawb cov txiaj ntsig thiab txo lub sijhawm tsis ua haujlwm.

2. Kev Kho Mob Kub thiab Kub Siab

Kev kho cua sov (annealing, quenching, sintering) xav tau cov khoom uas tiv taus qhov kub thiab txias hloov pauv thiab kub heev. Alumina ceramic rollers yog siv dav hauv cov hlau tsis yog ferrous (zinc, txhuas, tooj liab) thiab alloy kho cua sov rauv taws. Lawv qhov kev tiv thaiv thermal shock zoo heev (500 ° C hloov pauv sai) thiab kev tiv thaiv oxidation ua rau lawv zoo tagnrho rau kev xa cov workpieces los ntawm cov txheej txheem no.

Hauv kev ua hlau (kev ua hlau uas tsis yog ferrous, kev ua cov khoom siv hauv av), lawv ua haujlwm ua cov khoom siv thauj khoom uas tsis yooj yim hnav. Nrog rau qhov nyuaj ntawm Mohs ntawm 9 (qhov thib ob tsuas yog pob zeb diamond), lawv tiv taus kev txhuam, ua rau lub neej ntawm cov khoom siv ntev dua li cov menyuam hlau ib txwm muaj.

3. Kev Tsim Khoom Siv Semiconductor & Electronic

Kev lag luam semiconductor vam khom cov khoom siv ultra-pure, high-precision rau kev tsim microchip. Alumina ceramic rollers, nrog rau kev rwb thaiv hluav taws xob zoo heev (ntim resistivity txog li 10¹⁴Ω ・ cm) thiab cov khoom tsis huv, yog siv rau hauv kev tuav wafer. Lawv ua rau muaj qhov tseeb ntawm ± 1μm, txo cov kuab paug thiab txhim kho cov txiaj ntsig ntawm chip.

Lawv cov tshuaj lom neeg tsis muaj zog kuj tseem haum rau cov khoom siv hluav taws xob sintering furnaces, xa cov khoom rhiab heev (capacitors, resistors) yam tsis muaj kev cuam tshuam, ua rau lawv yog cov khoom siv tseem ceeb hauv kev lag luam.

4. Kev Tsim Khoom Siv Hluav Taws Xob Tshiab & Roj Teeb

Thaum lub zog tshiab nce siab zuj zus, cov menyuam no tseem ceeb heev rau kev tsim roj teeb - txij li cathode/anode sintering mus rau kev kho cua sov ntawm lub cell. Lawv tiv taus 1600 ° C thiab tiv taus electrolyte corrosion, thaum cov thermal conductivity qis ua kom lub cub tawg kub sib npaug, lav qhov ua tau zoo ntawm roj teeb thiab kev nyab xeeb.

Lawv kuj siv rau hauv kev ua cov roj hydrogen, tiv taus hydrogen embrittlement thiab tswj kev ruaj khov ntawm qhov kub thiab txias, txhawb kev loj hlob ntawm lub zog huv.

5. Kev Siv Tshuab Dav Hlau thiab Kev Ntsuas Qhov Tseeb

Kev lag luam aerospace suav tias lawv qhov hnyav (3.5g/cm³, ib nrab hlau) thiab lub zog siab yog qhov tseem ceeb, siv lawv rau hauv kev kho cua sov ntawm lub cav thiab cov txheej txheem satellite los txo qhov hnyav thaum tseem khaws cia kev ua haujlwm zoo, txhawb kev siv roj thiab lub peev xwm thauj khoom.

Hauv kev siv cov cuab yeej siv precision (kho qhov muag, cov khoom siv kho mob), lawv qhov tseeb ntawm qib micron (≤2μm qhov yuam kev ntev rau 200mm rollers) ua kom muaj kev ua haujlwm zoo. Biocompatibility kuj tseem siv tau rau kev siv kho mob xws li kev cog hniav.
