I-garnet sand abrasive yemvelo isibe yindlela ejwayelekile yokusika i-waterjet (AWJ) ngenxa yezakhiwo zayo ezilinganiselayo ngokomzimba, ngomshini, ngokomnotho nangokwezemvelo okungekho okunye ukuguguleka (i-aluminium oxide, i-silicon carbide, i-olivine, i-slag, i-glass bead) okungafanelana ngokuphelele. Ngezansi kukhona ukuhlukaniswa okugcwele kwamandla ayo:

1. Ukuqina Okulinganiselwe Kahle (Mohs 7.5–8.5)

• Kuqinile ngokwanele ukusika insimbi engagqwali, insimbi yekhabhoni, i-aluminium, itshe, ingilazi, i-ceramic, i-composite kanye ne-titanium ngempumelelo; kunikeza amazinga okususa izinto ngokushesha ngokungafani nezinto ezithambile (i-olivine, isihlabathi sengilazi, i-slag) ezisika kancane futhi zichithe ingcindezi yamanzi.
• Ayiqinile kakhulu njenge-aluminium oxide (Al₂O₃) noma i-silicon carbide (SiC). Ama-abrasives aqinile aqeda amashubhu okuxuba, agxilise ama-nozzle futhi anqume amakhanda ngokushesha okukhulu—anganciphisa impilo yesevisi yama-nozzle ngo-90% uma kuqhathaniswa ne-garnet, okuphakamisa izindleko eziphezulu zokufaka esikhundleni izingxenye ezisele.
• I-Garnet ifika endaweni efanelekile: amandla okusika aqinile + ukuguguleka kwemishini okulingene ukuze kwehliswe izindleko zokulungisa umshini isikhathi eside.
• 2. Ukuqina Okuhle kanye Nesakhiwo Sokusanhlamvu Okungahlungiwe Kancane
• Izinhlamvu ze-garnet zinokumelana okulinganiselwe kokuqhekeka (okungaqhekeka kancane). Uma zithinta izingxenye zokusebenza ngokucindezela okuphezulu kakhulu, izinhlamvu ziyaqhekeka ngokuqhekeka kwe-conchoidal ukuze ziveze njalo imiphetho emisha ebukhali yokusika kuyo yonke i-jet stream.
• Izinto zokukhuhla ezithambile ziyaqhekeka zibe uthuli olucolekile ngokushesha ngemva kokushayisana, zilahlekelwa amandla okusika ngokushesha futhi zidinga ukusetshenziswa okukhulu kokukhuhla.
• Izinto zokubhula eziqinile kakhulu zihlala ziphelele futhi zinemiphetho efiphele, okuholela ezindaweni ezisikiwe ezimagebhugebhu, ezigobile ezinemigqa ejulile.
• I-Garnet igcina ukusebenza kokusika okuqhubekayo ngevolumu encane yokudla kwesihlabathi, isindisa izindleko zokukhuhla ngokusika ngakunye.

• 3. Ubuningi Obufanele (~4.0 g/cm³)

  Ubuningi bayo bunzima ngokuphindwe kane kunamanzi, okuyisilinganiso esifanele sesisindo kuya kuvolumu yezinhlelo ze-AWJ

  Inzima ngokwanele ukuthola amandla e-kinetic anele uma isheshiswa yi-water jet enomfutho ophezulu ukuze igunde izinto eziqinile ngempumelelo.

• Akuyona into eqinile kakhulu ukuze yehluleke ukuxubana ngokulinganayo emfudlaneni wamanzi futhi ibangele ukusika okungalingani noma ukuvaleka kwejethi. Izinto zokuhudula eziphansi azikwazi ukudlulisa amandla anele okushaya, okuholela ekusikeni okuhamba kancane kanye nemiphetho emabi.
• 
• 4. Isimo Sezinhlayiyana Zemvelo Ezingaphansi Kwe-Angular Sekhwalithi Ephakeme Yokusika
• Izinhlamvu ze-garnet ezimsulwa zine-geometry ebukhali, engalingani ye-sub-angular:
• Ikhiqiza imiphetho yokusika ebushelelezi kakhulu, engenama-burr enobubanzi obuncane be-kerf; ukugaya/ukupholisha kwesibili ngokuvamile akudingeki.
• Ezinye izindlela ezifana nobuhlalu beglasi obuyindilinga zidala ukupholisha ubuso kuphela ngaphandle kwamandla okusika ajulile; ama-slag abrasives akhiqiza ukunamathela okunzima kanye nemihuzuko ebusweni ezingxenyeni eziqediwe.
• Ububanzi be-mesh buyatholakala (60# / 80# / 100#): i-grit eqinile yokusika insimbi ejiyile/itshe ngokushesha, i-grit encane yokusika ipuleti elincane ngokunemba, ingilazi kanye nokusika amaphethini okuyinkimbinkimbi.
  

  5. Ukugqokwa Kwemishini Okuphansi kanye Nezindleko Zokusebenza Eziphansi

  Lena enye yezinzuzo ezinkulu ze-garnet kwezentengiselwano:

• Ukuguguleka okuhamba kancane kwezinto ezibalulekile ezisetshenziswayo: amapayipi okuxuba, ama-nozzle ayigugu, amakhanda okusika, amaphampu namapayipi uma kuqhathaniswa nezinto zokwenziwa eziqinile kakhulu.
• Izinga lokusetshenziswa okunamandla eliphansi ngeyunithi ngayinye yokusikwa kwezinto; i-garnet yemvelo ishibhile ngethani kune-aluminium oxide noma i-silicon carbide.
• Isikhathi esincane sokungasebenzi sokushintsha i-nozzle/i-tube, ukukhulisa ukusetshenziswa komshini kanye nomphumela wokukhiqiza jikelele.
• Ayisebenzi ngamakhemikhali, ayisebenzi ngazo zonke izinto ezivamile ezisikiwe (izinsimbi zensimbi/ezingenazo insimbi, imabula, igranite, igwebu, i-carbon fiber, ingilazi, irabha) futhi ayithathi hlangothi ekugelezeni kwamanzi okucindezela okuphezulu
• Akukho kungcola ngamakhemikhali, ukungcoliswa kwe-oxidation noma ubuso ezindaweni zokusebenza eziqediwe, kubalulekile ekusikeni kwezindiza, izinga lokudla kanye nezingxenye zezokwelapha.
• Imelana ne-asidi kanye ne-alkali, ifanele ukusika i-alloy ekhethekile kanye nezinto ezimelana nokugqwala.
• Amaminerali ambiwe ngokwemvelo nge-silica ekhululekile ephansi kakhulu, okususa izingozi zempilo ze-silicosis ezilethwa yisihlabathi se-silica kubasebenzisi.
• Ikhiqiza uthuli oluncane kakhulu oluhamba emoyeni ngesikhathi sokusika kune-slag, i-olivine noma i-crushed stone abrasives, okwenza kube lula ukukhipha uthuli kanye nemithwalo yesistimu yokungenisa umoya.
• Imfucuza engenabo ubuthi, engenansimbi esindayo; i-slurry ye-garnet esetshenzisiwe ingaphinde isetshenziswe (ihlolwe kabusha ukuze inqunywe/iqhunyiswe okwesibili) noma isetshenziswe kabusha njenge-aggregate filler ye-asphalt, ukhonkolo kanye nezinto zokwakha ngaphandle kwezimali zokulahla imfucuza eyingozi.

• 6. Ukuqina Kwamakhemikhali Okuhle Kakhulu Nokuhambisana Nezinto Ezibanzi

  7. Indawo Yokusebenza Enobungani Nemvelo, Ephansi Kothuli Futhi Ephephile

  8. Ukuphinda kusetshenziswe

  I-slurry ye-garnet esetshenzisiwe ingahlungwa, igezwe futhi ihlelwe kabusha ukuze isetshenziswe kabusha ekusikeni okunembile okuphansi kuya kokuphakathi noma ekuqhumeni komhlaba, okunciphisa kakhulu izindleko zezinto kanye nokukhishwa kwemfucuza—inzuzo engafinyeleleki ye-abrasives yokwenziwa elahlwayo.

  Ukuqhathanisa Okusheshayo vs Ezinye Iziphazamiso Ezivamile

  Isifinyezo

  Isihlabathi se-garnet sidlula zonke izimbangi ngoba silinganisela ukusebenza kahle kokusika, ukunemba kwendawo, impilo yesevisi yomshini, izindleko zokusebenza kanye nokuphepha kwemvelo konke ngesikhathi esisodwa—akukho okunye ukuklwebheka okungaletha lokhu kusebenza okuphelele, okwenza kube yinto ejwayelekile evelele yezindawo zokusebenzela zokusika ama-waterjet emhlabeni wonke.
