Zirconia Alumina cov xuab zeb hauv teb kev ua hlau

 

I. Keeb kwm muaj zirconia colundum bandpaper

Lub hnub nyoog ntawm Zircama Alumina Sandpaper cim ib lub ntsiab lus nyob rau hauv abrasive tshuab kev hloov kho ntawm 20 caug xyoo.

 

Ii. Cov ntaub ntawv txuj ci, Eutectic Cov Qauv

Cov tshuaj siv tshuaj essence ntawm zirconia alumina yog Eutecic Composite ntawm Aluminium Oxide (Al₂o₃) thiab zirconium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (ZroConium oxide (Zroirnon Los ntawm kev kub siab - kub yaj nyob rau hauv ib qho hluav taws xob sib xyaw ua saum toj no 2000℃sau cov Crystal theem ntawm zircon (zog teb). Tus qauv no xaus zirconia alumina nrog peb cov ntsiab lus zoo:

      Gradient hardness yam ntxwv: Raws li Zro₂ cov ntsiab lus (10% {- 40%), zirconia alumina tuaj yeem faib rau hauv qis, cov tiaj. Kev sim cov ntaub ntawv qhia tau tias ZA40 (nrog 40% ZO₂ cov ntsiab lus) ua tiav cov sib tsoo ntim ntawm lub tshuab sib tsoo ntawm cov neeg sib tsoo.

     Cov me me pob txha lov Tov: Lub pob txha lov todness ntawm zirconia alumina ncav cuag 5.2 mpa ₂ / ₂, deb tshaj plaws ntawm dawb alumina (3.8 mpa · / ₂). Qhov no txhais tau tias kev sib tsoo cuam tshuam, zirconia qos qoob loo tsim ib lub micro- nrum network txiav thiab tswj cov khoom siv tshiab kom zoo.

    Thermal ruaj khov: Lub thermal conductivity ntawm zirconia alumina yog 0.2718 cal / cmor · kev ruaj khov, thiab nws tuaj yeem tswj hwm kev ruaj ntseg ntawm qhov kub ntawm 1000 degree. Cov xeeb ceem no ua rau nws zoo tshaj plaws abrasive rau qhov nyuaj- {4 {}-} raws li alloys thiab titanium alloys.

 

 

III. Cov txheej txheem tsim khoom

    1. Raw Khoom Siv Rawific: Xaiv cov siab -} Zoo zircon xuab zeb (Zrifeum Cawv
    2. Eutectic Melting: Sib tov Zro₂ nrog cov hmoov av alumin, ntxiv tio₂, cr₂o₃ thiab lwm yam ntxiv, thiab sau ib qho kev sib ntxiv, thiab ua kom muaj lwm yam ntxiv} tus txiv duaj oxide eutectic rauv taws.
    3. Crushing thiab ntsuam xyuas: Txias zircon corundum blocks, tom qab ntawd tsoo lawv nrog lub puab tsaig crusher thiab screen lawv los ntawm ib qho kev faib tawm hydraulic kom tau txais cov sib txawv ntawm cov loj me (F36-F2000).
    4. Cov xuab zeb electrostatic implantation: Siv qhov siab -} voltage electrostatic teb (5-10
    5. Resin Kho: Tom qab coating nrog phenolic resin binder, cov xuab zeb yog ci ntawm 180℃rau tag nrho kho lub zog ntawm 8.5 n / mm² rau abrasive.
    6. Tshaj tawm -} kev kho: Txheej txheem cov xuab zeb rau hauv rolls, cov ntawv txheeb lossis cov duab tsis xwm yeem siv ultra - precision txiav cov khoom sib tsoo.

 

 

IV. Cov Khoom Siv Lub Cev

 

    Kev ntsuas hardness: Mohs hardness 9.0, knoop hardness 1450-2000 kg / mg / mm², muaj peev xwm ntawm txiav nyuaj alloys nrog lub hardness ntawm dhau hrc50.
    Puas Ua Haujlwm Kev Ntsuam Xyuas: Ntawm ML-10 qhov kev ua phem, cov hnav ntim ntawm zirconia alumina cov xuab zeb tsuas yog 60% ntawm cov silicon carbide xuab zeb, thiab nws cov kev pabcuam lub neej tau txuas ntxiv los ntawm 2.5 zaug.
    SELF - Lub Zog Kev Soj Ntsuam: Los ntawm kev ntsuas hluav taws xob electron me me) (SEM) Alummina Alumina cov nplais txuas ntxiv mus ua cov khoom tshiab thaum sib tsoo, tswj hwm qhov chaw ntawm Ra0.4 μm.
 Xav Yuam Kev Ntsuas: Nyob rau hauv 1j cuam tshuam lub zog, zirconia alumina crackpape khaws cia 95% ntawm nws qhov kev txiav kev ua tiav, thaum muaj alumina crumpilation tsuas yog khaws cia 78%.

V. Daim Ntawv Thov Kev Thov

 

    Ib tug tub rog: Rau kev ua inconel 718 nickel {{1} based alloy turning lub sij hawm yog txo los ntawm 30%, thiab cov kev ntxhov siab saum npoo txo ​​los ntawm 50%.
   Kev Siv Nkab Automotive: Hauv lub tog raj kheej block honing txheej txheem ua tiav ib qho chaw ntawm RA0.2μm, txo lub cav roj roj tau haus los ntawm 2%.
   Pwm Raug: Rau kev ua kom meej meej polishing ntawm H13 steel hlau pwm nce ntxiv daim iav nto sib txuam los ntawm 40%, mus txog ntawm qhov ci ntawm # 8000.
   Khoom Siv Khoom Siv Zog: Nyob rau hauv phab ntsa sab hauv sib tsoo ntawm lub zog ua haujlwm ntawm lub zog ua haujlwm hauv lub zog

 

 

VI. Kev Siv thiab Kev Txij Nkawm: Txoj kev tshawb fawb rau lub neej pabcuam sijhawm ntev
Yog siv thiab kev saib xyuas yog cov yuam sij rau kev ua kom zoo tshaj plaws ntawm Zirconia Alumina Sandpaper:

1. Kev xaiv abrasive promaterciples:
Kev sib tsoo ntawm kev sib tsoo (F36-F80): Tshem tawm cov nplai thiab Weld Seams
Kev sib tsoo kom zoo (F120-F320): Theem Sab Theem
Superfine Sib Tsoo (F400-F2000): Daim iav Polishing
2. Kev tswj siab:
Nws raug nquahu kom siv cov kab tawm ntawm 0.8-1.5n / cm². Ntau dhau los yuav ua rau daim ntawv abrasive ua npub sai sai, thaum tsis muaj kev sib tsoo kom txo tau kev sib tsoo.
3.Txoj kev ua tswv yim:
Kev sib tsoo qhuav, siv cov sib sib tsoo sib tsoo thiab txias rau 1 feeb txhua 5 feeb. Kom ntub kev sib tsoo, siv dej - Soluble tej kua dej nrog lub concentration ntawm 3-5%.
4. Kev tswj kev cai:
Chaw Cia Ib Cheeb Tsam Muaj Tsawg Dua lossis sib npaug rau 60%, Kub 15-25 Degree
Ntxuav cov ntaub ntawv saum npoo tom qab siv kom tsis txhob khawb ntawm cov khoom tawv
Nquag xyuas lub tiaj tus ntawm cov ntawv abrasive. Hloov nws yog tias deformation ntau dua 0.5 hli.
