I-garnet sand abrasive yendalo iye yaba yi-abrasive eqhelekileyo yokusika i-waterjet (AWJ) ngenxa yeempawu zayo zomzimba, zoomatshini, zoqoqosho kunye nezokusingqongileyo ezilungelelaniswe ngokugqibeleleyo apho kungekho enye i-abrasive (i-aluminium oxide, i-silicon carbide, i-olivine, i-slag, i-glass bead) enokulingana ngokupheleleyo. Apha ngezantsi kukho uhlalutyo olupheleleyo lwamandla ayo:

1. Ubulukhuni Obulungeleleneyo (Mohs 7.5–8.5)

• Iqinile ngokwaneleyo ukusika intsimbi engagqwaliyo, intsimbi yekhabhoni, i-aluminium, ilitye, iglasi, i-ceramic, i-composite kunye ne-titanium ngokufanelekileyo; inika amazinga okususa izinto ngokukhawuleza ngokungafaniyo nezinto ezithambileyo (i-olivine, isanti yeglasi, i-slag) ezisika kancinci kwaye zichithe uxinzelelo lwamanzi.
• Ayiqinanga kakhulu njenge-aluminium oxide (Al₂O₃) okanye i-silicon carbide (SiC). Ii-abrasives eziqinileyo zitshabalalisa iityhubhu zokuxuba, zigxile kwii-nozzles kwaye zisika iintloko ngokukhawuleza kakhulu—zinokunciphisa ubomi benkonzo yee-nozzles ukuya kuthi ga kwi-90% xa kuthelekiswa ne-garnet, nto leyo enyusa iindleko eziphezulu zokutshintshwa kwezixhobo ezisele.
• IGarnet iphumelele kakhulu: amandla okusika aqinileyo + ukuguguleka kwezixhobo okuphakathi ukuze kuncitshiswe iindleko zokugcinwa komatshini ezisebenza ixesha elide.
• 2. Ukuqina Okufanelekileyo kunye nolwakhiwo lweenkozo eziqhekekayo kancinci
• Iinkozo zeGarnet zinokumelana nokuqhekeka okuphakathi (ezinokuqhekeka kancinci). Xa zibetha izinto zokusebenza ngoxinzelelo oluphezulu kakhulu, iinkozo ziyaqhekeka ecaleni kweenkozo zeconchoidal ukuze ziqhubeke nokuveza imiphetho emitsha ebukhali ye-angular cutting kuyo yonke i-jet stream.
• Izinto ezithambileyo ezirhabaxa ziyacolwa zibe luthuli olucolekileyo ngoko nangoko emva kokungqubana, zilahlekelwa ngumthamo wokusika ngokukhawuleza kwaye zifuna ukusetyenziswa okuphezulu kokurhabaxa.
• Izinto ezirhabaxa eziqinileyo zihlala ziqinile kwaye zinomphetho omdaka, nto leyo ebangela ukuba iindawo ezisikiweyo zibe rhabaxa, zigobile kwaye zibe nemiqolo enzulu.
• I-Garnet igcina ukusebenza kokusika rhoqo kunye nomthamo omncinci wesanti yokutya, igcina iindleko zokurhawuzelela ngokusika ngakunye.

• 3. Uxinano oluLungileyo (~4.0 g/cm³)

  Ubunzima bayo buphindwe kane ngaphezu kwamanzi, umlinganiselo ofanelekileyo wobunzima ukuya kumthamo kwiinkqubo ze-AWJ

  Zinzima ngokwaneleyo ukufumana amandla e-kinetic aneleyo xa zikhawuleziswa yi-water jet enoxinzelelo oluphezulu ukuze zichebe izinto eziqinileyo ngokufanelekileyo.

• Ayixinene kakhulu ukuze ingaphumeleli ukuxubana ngokulinganayo kumjelo wamanzi kwaye ibangele ukusika okungalinganiyo okanye ukuvaleka kwejethi. Izinto ezirhabaxa ezinoxinano oluphantsi azikwazi ukuhambisa amandla aneleyo okungqubana, nto leyo ekhokelela ekunqumleni okucothayo kunye nemiphetho erhabaxa.
• 
• 4. Imilo yeParticle yeNdalo engaphantsi kwe-Angular yoMgangatho oPhezulu wokuSika
• Iigrains zegarnet ezicocekileyo zinejometri ebukhali nengalinganiyo ye-sub-angular:
• Ivelisa imiphetho yokusika egudileyo kakhulu, engenamigxobhozo enobubanzi obuncinci be-kerf; ukugaya/ukupolisha okwesibini kudla ngokungabalulekanga.
• Ezinye iindlela ezifana neentsimbi zeglasi ezingqukuva zenza kuphela ukupholisha umphezulu ngaphandle kwamandla okusika anzulu; izinto ezisusa inkunkuma zivelisa ukugquma okunzima kunye nemikrwelo yomphezulu kwiindawo ezigqityiweyo.
• Uluhlu olubanzi lwe-mesh luyafumaneka (60# / 80# / 100#): i-grit erhabaxa yokusika isinyithi esityebileyo/ilitye ngokukhawuleza, i-grit ecolekileyo yokusika ipleyiti ebhityileyo ngokuchanekileyo, iglasi kunye nokusika iipateni ezintsonkothileyo.
  

  5. Ukunxiba kwezixhobo okuphantsi kunye neendleko zokusebenza ezisezantsi

  Le yenye yezona nzuzo zinkulu zorhwebo zegarnet:

• Ukuwohloka okucothayo kwezinto ezibalulekileyo ezisetyenziswayo: iityhubhu zokuxuba, ii-nozzles zejewel, iintloko zokusika, iimpompo kunye neepayipi ngokuchasene nezinto eziqholiweyo eziqinileyo ezenziweyo.
• Izinga lokusetyenziswa kwe-abrasive eliphantsi ngeyunithi nganye yokusika; i-garnet yendalo ixabisa kancinci ngetoni nganye kune-aluminium oxide okanye i-silicon carbide.
• Ixesha elincinci lokungasebenzi lokutshintsha umlomo/ityhubhu, ukunyusa ukusetyenziswa komatshini kunye nokuveliswa kwemveliso iyonke.
• Ayisebenzi ngokweekhemikhali, ayisebenzi kuzo zonke izinto eziqhelekileyo ezisikiweyo (iintsimbi ze-ferrous/non-ferrous, imabula, igranite, ifoam, i-carbon fiber, iglasi, irabha) kwaye ayithathi cala xa amanzi enoxinzelelo oluphezulu.
• Akukho dayi yeekhemikhali, i-oxidation okanye ungcoliseko lomphezulu kwiindawo zokusebenza ezigqityiweyo, zibalulekile ekusikeni inqwelo moya, ukutya kunye nokusika izinto zonyango.
• Iyamelana ne-asidi kunye ne-alkali, ifanelekile ukusika i-alloy ekhethekileyo kunye nezinto ezimelana nokubola.
• Iiminerali ezimbiwe ngokwendalo nge-silica ekhululekileyo ephantsi kakhulu, nto leyo esusa iingozi zempilo ze-silicosis eziziswa sisihlabathi se-silica kubaqhubi.
• Ivelisa uthuli oluncinci kakhulu oluhamba emoyeni ngexesha lokusika kune-slag, i-olivine okanye i-crushed stone abrasives, nto leyo eyenza kube lula ukukhupha uthuli kunye nemithwalo yenkqubo yokungenisa umoya.
• Inkunkuma engenabungozi, engenasinyithi esinzima; i-garnet slurry esetyenzisiweyo ingaphinda isetyenziswe (ihlolwe kwakhona ukuze inqunyulwe/iqhunyiswe okwesibini) okanye isetyenziswe kwakhona njengesizalisi se-asphalt, ikhonkrithi kunye nezixhobo zokwakha ngaphandle kwentlawulo yokulahla inkunkuma enobungozi.

• 6. Uzinzo oluBalaseleyo lweeKhemikhali kunye nokuhambelana kwezinto ezibanzi

  7. Indawo yokusebenzela enobuhlobo nokusingqongileyo, enothuli oluphantsi kwaye ikhuselekile

  8. Ukukwazi ukuphinda kusetyenziswe

  I-slurry ye-garnet esetyenzisiweyo ingahluzwa, ihlanjwe kwaye ihlelwe ngokutsha ukuze isetyenziswe kwakhona ekusikeni okuchanekileyo okuphantsi ukuya kokuphakathi okanye ekuqhumiseni umphezulu, nto leyo enciphisa ngakumbi iindleko zezinto kunye nokukhutshwa kwenkunkuma—inzuzo engenakufikeleleka kwizinto ezilahlwayo ezenziweyo.

  Ukuthelekisa Okukhawulezileyo vs Ezinye Ii-Abrasives Eziqhelekileyo

  Isishwankathelo

  Isanti yeGarnet iphumelela ngaphezu kwazo zonke ezinye izimbangi kuba ilungelelanisa ukusebenza kakuhle kokusika, ukuchaneka komphezulu, ubomi benkonzo yoomatshini, iindleko zokusebenza kunye nokhuseleko lokusingqongileyo ngaxeshanye—akukho enye into erhabaxa enokwenza oku kusebenza ngokupheleleyo, nto leyo eyenza ukuba ibe yeyona nto iphambili kwiiworkshop zokusika i-waterjet kwihlabathi liphela.
