Cov xuab zeb garnet ntuj tau dhau los ua cov khoom siv txhuam thoob ntiaj teb rau kev txiav dej abrasive (AWJ) vim nws cov khoom siv lub cev, kev siv tshuab, kev lag luam thiab ib puag ncig zoo sib npaug uas tsis muaj lwm yam khoom siv txhuam (aluminum oxide, silicon carbide, olivine, slag, iav hlaws dai) tuaj yeem sib piv tau zoo. Hauv qab no yog kev faib tawm tag nrho ntawm nws cov zog:

1. Kev Nyuaj Siab Sib Npaug Zoo Kawg Nkaus (Mohs 7.5–8.5)

• Nyuaj txaus los txiav cov hlau tsis xeb, cov hlau carbon, txhuas, pob zeb, iav, ceramic, composite thiab titanium tau zoo; muab cov khoom tshem tawm sai sai tsis zoo li cov khoom siv abrasives mos (olivine, iav xuab zeb, slag) uas txiav qeeb thiab pov tseg dej siab.
• Tsis tawv dhau zoo li txhuas oxide (Al₂O₃) lossis silicon carbide (SiC). Cov khoom siv abrasives superhard ua rau cov raj sib tov lwj, ua rau cov nozzles thiab cov taub hau txiav sai heev - lawv tuaj yeem ua rau lub neej ua haujlwm ntawm nozzle luv dua txog li 90% piv rau garnet, ua rau cov nqi hloov khoom seem siab dua.
• Garnet ntaus qhov chaw zoo tshaj plaws: lub zog txiav muaj zog + kev hnav khoom siv nruab nrab kom txo cov nqi kho tshuab mus sij hawm ntev.
• 2. Kev Ruaj Ntseg Zoo Tshaj Plaws & Cov Qauv Nplej Semi-Friable
• Cov noob garnet muaj qhov tsis kam tawg nruab nrab (semi-friable). Thaum cuam tshuam rau cov workpieces ntawm qhov siab heev, cov noob tawg raws cov pob txha conchoidal kom pom cov ntug txiav ntse tshiab thoob plaws hauv cov dej ntws.
• Cov khoom siv abrasive mos mos yuav tawg ua hmoov me me tam sim ntawd tom qab raug tsoo, ua rau lub peev xwm txiav poob sai sai thiab xav tau kev siv abrasive ntau dua.
• Cov khoom siv abrasives uas tawv dhau lawm tseem zoo li qub nrog cov npoo tsis ci, ua rau cov nplaim txiav ntxhib, jagged nrog cov kab tob.
• Garnet tswj tau qhov kev txiav zoo sib xws nrog qhov ntim xuab zeb tsawg dua, txuag cov nqi abrasive rau ib qho kev txiav.

• 3. Qhov Ceev Zoo Tshaj Plaws (~ 4.0 g / cm³)

  Nws qhov ceev yog 4 npaug hnyav dua li dej, qhov sib piv ntawm qhov hnyav thiab qhov ntim zoo tshaj plaws rau AWJ systems.

  Hnyav txaus kom tau txais lub zog kinetic txaus thaum nrawm los ntawm lub tshuab dej siab kom txiav cov khoom tawv kom zoo.

• Tsis ntom dhau kom tsis sib xyaw sib npaug hauv cov dej ntws thiab ua rau txiav tsis sib npaug lossis txhaws. Cov khoom siv abrasives uas tsis ntom dhau tsis tuaj yeem xa cov zog sib tsoo txaus, ua rau txiav qeeb thiab ntug ntxhib.
• 
• 4. Cov duab puab me me uas zoo li lub pob zeb ntuj rau qhov zoo tshaj plaws
• Cov noob garnet ntshiab muaj cov duab geometry ntse, tsis sib npaug ntawm cov ces kaum hauv qab:
• Tsim cov ntug txiav uas du thiab tsis muaj burr nrog qhov dav kerf tsawg kawg nkaus; kev sib tsoo/kev txhuam thib ob feem ntau tsis tsim nyog.
• Lwm txoj hauv kev zoo li cov hlaws iav puag ncig tsuas yog tsim cov nplaim ci xwb yam tsis muaj lub zog txiav tob; cov slag abrasives tsim cov kab nrib pleb hnyav thiab khawb ntawm qhov chaw tiav lawm.
• Muaj ntau hom mesh (60# / 80# / 100#): cov xuab zeb ntxhib rau cov hlau tuab/pob zeb txiav sai, cov xuab zeb zoo rau cov phaj nyias, iav thiab cov qauv txiav nyuaj.
  

  5. Kev Siv Khoom Siv Tsawg & Tus Nqi Ua Haujlwm Tag Nrho Qis Dua

  Qhov no yog ib qho ntawm garnet qhov zoo tshaj plaws hauv kev lag luam:

• Kev puas tsuaj qeeb dua ntawm cov khoom siv tseem ceeb: cov raj sib tov, cov taub hau pob zeb diamond, cov taub hau txiav, cov twj tso kua mis thiab cov kav dej piv rau cov khoom siv hluavtaws superhard abrasives.
• Tus nqi siv abrasive qis dua rau ib chav tsev txiav cov khoom siv; garnet ntuj pheej yig dua ib tuj dua li txhuas oxide lossis silicon carbide.
• Tsawg dua lub sijhawm tsis ua haujlwm rau kev hloov lub nozzle / raj, ua kom muaj kev siv tshuab ntau dua thiab ua rau muaj txiaj ntsig ntau ntxiv.
• Chemically inert, non-reacting nrog txhua yam khoom siv txiav (ferrous / non-ferrous hlau, marble, granite, ua npuas ncauj, carbon fiber, iav, roj hmab) thiab nruab nrab hauv cov dej ntws siab
• Tsis muaj tshuaj lom neeg staining, oxidation lossis kev ua qias tuaj ntawm qhov chaw ua tiav, qhov tseem ceeb rau kev txiav cov khoom siv aerospace, qib zaub mov thiab cov khoom siv kho mob.
• Acid & alkali resistant, tsim nyog rau kev txiav cov hlau tshwj xeeb thiab cov ntaub ntawv tiv taus corrosive.
• Cov zaub mov uas tau khawb los ntawm ntuj tsim uas muaj silica tsawg heev, tshem tawm cov kev pheej hmoo ntawm kev noj qab haus huv ntawm silicosis uas xuab zeb silica coj los rau cov neeg ua haujlwm.
• Tsim cov hmoov av me me tsawg dua li cov slag, olivine lossis cov pob zeb tawg, ua rau kev rho tawm hmoov av thiab kev ua pa ntawm lub tshuab yooj yim dua.
• Cov khib nyiab tsis muaj tshuaj lom, tsis muaj hlau hnyav; cov garnet slurry siv lawm tuaj yeem rov ua dua tshiab (rov tshuaj xyuas rau kev txiav / blasting thib ob) lossis rov siv dua ua cov khoom ntim rau asphalt, concrete thiab cov ntaub ntawv tsim kho yam tsis muaj nqi pov tseg cov khib nyiab phom sij.
• 

• 6. Kev Ruaj Ntseg Tshuaj Zoo heev & Kev Sib Tw Dav Dav

  7. Chaw Ua Haujlwm Zoo Rau Ib puag ncig, Tsis Muaj Plua Plav & Muaj Kev Nyab Xeeb

  8. Kev siv rov qab tau

  Cov kua nplaum garnet uas siv lawm tuaj yeem lim, ntxuav thiab rov faib ua pawg dua rau kev siv dua hauv kev txiav qhov tseeb qis mus rau nruab nrab lossis kev tua qhov chaw, txo cov nqi khoom siv thiab cov khib nyiab tawm ntxiv - qhov txiaj ntsig tsis tau rau cov khoom siv hluavtaws pov tseg.

  Kev Sib Piv Sai vs Lwm Cov Abrasives Feem Ntau

  Kev Txheeb Xyuas

  Cov xuab zeb garnet ua tau zoo dua txhua tus neeg sib tw vim nws sib npaug ntawm kev txiav zoo, qhov tseeb ntawm qhov chaw, lub neej ua haujlwm ntawm lub tshuab, tus nqi khiav thiab kev nyab xeeb ib puag ncig tag nrho ib zaug - tsis muaj lwm yam abrasive tuaj yeem xa qhov kev ua tau zoo no, ua rau nws yog cov khoom siv tseem ceeb rau kev cob qhia txiav dej thoob ntiaj teb.
