Cov kev pabcuam lub neej ntawm hnav-tiv thaiv Mosaic meem txheej: qhov kev pabcuam lub neej ntawm hnav-tiv taus cov nplais ceramic dua li qhov zoo uas muaj kev txhawj xeeb nrog nws tus kheej sab nraud, ib qho tseem ceeb yog sab nrauv qhov, nws yeej suav nrog qhov nruab nrab cov qoob loo loj, tawv, txoj kev txhuam, ib puag ncig, thauj khoom, scour ceev, qhov kub thiab lub sijhawm tos.Qhov dav dav, qhov me me qhov loj me, qhov qis qis dua qhov qis, qhov qis ntawm qhov nplawm tawg, qhov me me ntawm lub taub hau tawg, ntev dua kev pab cuam lub neej ntawm hnav-tiv taus cov ntawv ceramic. Feem ntau hauv kev sib txuas ntawm lub network ntawm lub slag hmoov ntau lawm kab, thaj tsam ntawm thaj chaw ntawm cov hmoov yog {{3}} ~ 450 m 2 / kg, lub siab yog {{6 }} g / Nm 3, qhov nrawm yog 2 8 ~ 3 0m / s, tus yaig Lub kaum ntse ntse yog 3 0 ℃, hnav 2 0 hli hnav -resistant ceramic daim ntawv tuaj yeem siv rau 8 ~ 10 xyoo.Raw kev sib tsoo thiab clinker sib tsoo cov ntaub ntawv yooj yim dua los zom dua li slag, tib cov tuab ntawm hnav-resistant ceramic daim ntawv, kev pab lub neej tuaj yeem ncav ntau dua {{1 4}} xyoo.
Cov yam ntxwv ntawm hnav tsis taus alumina microcrystalline hauv ob sab phlu: 1, siab hardness, hnav tsis kam, yaig tsis kam: 92 plooj (venice), {{{{5}}}, cov plooj (veneers) alumina hnav tiv taus tej daim ceramic, rockwell hardness ntawm hra 8 5 - 9 5, piv rau pob zeb diamond, hnav tsis kam yog siab dua li ntawm manganese steel thiab siab cam khwb cia hlau, nyob rau hauv tib lub sijhawm ua haujlwm tuaj yeem ncua kev pab lub neej ntawm cov khoom siv ntau dua 1 0 zaug; {{{5}}. Zoo heev tiv taus rau qhov kub thiab kub kom sov: nws tuaj yeem khiav mus ntev ntev ntawm 750 ℃; 3. Ua rau cov kua qaub thiab alkali ua rau xeb: alumina hnav-tiv thaiv cov ntaub ceramic muaj cov tshuaj lom neeg ruaj khov, tiv taus acid thiab alkali corrosion, tiv thaiv oxidation, thiab yoog raws ntau yam kev ua haujlwm hnyav; 4, lub teeb yuag: hnav-resistant ceramic daim ntawv ntom ntawm 3. 5 - 3. 8 g / cm 3, tsuas yog ib nrab ntawm cov hlau, tuaj yeem txo qhov hnyav ntawm cov khoom siv; 5, muaj zog sib khi, tsis yooj yim kom poob: hnav-resistant ceramic daim tuaj yeem siv los tiv thaiv kub inorganic nplaum nplaum, koov sib koom thiab cov vuam sib txuas thiab lwm txoj hauv kev ruaj khov, tuaj yeem ua kom paub tseeb tias cov xeb hauv cov kub , kev cuam tshuam loj rau lub sijhawm ntev kom tsis txhob poob.
Cov txheej txheem los kho cov kav dej txuas nrog hnav-tiv thaiv alumina microcrystalline hauv ob sab: ntxuav cov kav dej saum npoo → kho lub cev → polish thiab du → muab cov ntawv no → welding → nrhiav kom tau tuab → kuaj xyuas nws tus kheej.
Npaj: kev yuav khoom siv, khoom siv debugging, kev tsim kho cov neeg ua haujlwm, txuas hluav taws xob, cua xa mus, thiab lwm yam.
1. Ntxuav cov yeeb nkab nto: ua haujlwm zoo tshem cov av, xeb thiab lwm yam sundries.
Ii. Polishing: lub yeeb nkab phab ntsa yog kho los ntawm Angle grinder, thiab nws yog qhov yuav tsum tau hais tias cov yeeb nkab phab ntsa tsis pub los ntawm ntab thiab xeb. kom ua tiav cov qauv zoo.
Peb, kev ntsuas cais tawm: tom qab tshem tawm ntawm cov khib nyiab, yuav tsum khaws cia rau hauv chaw hluav taws xob qhuav, kom tiv thaiv kom tsis txhob muaj kuab paug.
4. Khaws cov micro-crystalline coj-resisting alumina txheej: sib xyaw ntu A thiab tshooj B hauv kev faib ua feem, muab tshuaj txhuam tusyees tusyees tom qab sib tov, tusyees zom cov ceramic qhov chaw, tsis muaj qhov ua kom muaj qhov ntsej muag virtual thiab tiv thaiv kev tshwm sim, cov coj-resisting ceramic txheej yog tus, qhov qhov sib txawv nruab nrab ntawm phaj thiab phaj yog tsawg dua 0. 4 mm.The ceramic phaj muaj du seams.
Tsib, vuam: cov cuab yeej kho vajtse tso rau hauv cov nplais ceramic ntawm lub qhov, vuam qhov ntev tag nrho ntawm lub tshuab vuam, nrog lub taub hau ceramic yuav raug muab lo rau saum npoo ntawm qhov kho vajtse.
Vi. Kev kuaj tus kheej: tom qab txuas lub qhov chaw ceramic, kev kuaj tus kheej yuav tsum tau ua, thiab cov khoom tsis muaj qhov tsim nyog yuav rov ua dua, thiab tom qab ntawd kev tshuaj xyuas tus kheej yuav tsum ua.
Kev coj los tiv thaiv thev naus laus zis zoo dua ntawm kev hnav-tiv thaiv Mosaic meem:
1. Lub hardness yog siab dua HRA 86, thib ob tsuas yog pob zeb diamond, thiab deb tshaj qhov hnav tsis kam ntawm hnav-tiv taus cov hlau thiab bimetal puas phaj.Wear-resisting ceramic daim ntawv adopts 95% Al {{5} } ntxiv rau ntau yam kev sib txawv ntawm cov khoom hnav coj los tiv thaiv cov mis, uas muaj cov yam ntxwv ntawm kev kub siab, siab toughness thiab hnav-tiv taus.Qhov zoo, hnav tsis kam, hnav tsis kam rau tshaj manganese hlau 266 zaug, siab chromium nrum hlau 1 7 1.
Peb, lub teeb phaus, tsuas yog ib nrab ntawm qhov hnyav ntawm steel, tuaj yeem txo qhov hnyav ntawm cov khoom siv.
Iv. Cr 203 thiab Ti 02, uas zoo heev li cov ntxaij ntoo ntawm A 1203, tau muab coj los ua cov txheej txheem ntawm kev poob siab tsis kam thiab hnav resistant ceramics.Meanwhile, zinc oxide whisker tau ntxiv nyob rau hauv cov txheej txheem sintering los tsim cov khoom nplej zoo nrog A 1203, rov qab lis qhov loj me, txhawb kom sintering thiab txhim kho pob txha tawv.Qhov pob txha tawv ntawm cov ntoo zoo-ceramics yog kic (GG gt; 4. {{ 6}} Mpa / m).
Cov nplaum muaj qhov ua kom muaj zog thiab zoo thaum tshav kub kub tiv thaiv.Yog li xyuas kom meej tias cov hnav-daim ntaub ceramic tsis poob tawm nyob ntev ntev hauv qhov kub.
