Ua lilo ka mea hoʻopōʻino one garnet maoli i mea hoʻopōʻino maʻamau no ka ʻoki ʻana i ka wai jet abrasive (AWJ) ma muli o kona mau waiwai kino, mechanical, hoʻokele waiwai a me ke kaiapuni i kaulike maikaʻi ʻia ʻaʻole hiki i kekahi mea hoʻopōʻino ʻē aʻe (aluminium oxide, silicon carbide, olivine, slag, glass bead) ke hoʻohālikelike piha. Aia ma lalo kahi wehewehe piha o kona mau ikaika:

1. Paʻakikī Kaulike Kūpono (Mohs 7.5–8.5)

• Paʻakikī e ʻoki i ke kila kila, ke kila kalapona, ka alumini, ka pōhaku, ke aniani, ka seramika, ka hui pū ʻana a me ka titanium me ka maikaʻi; hāʻawi i nā wikiwiki wehe mea ʻaʻole e like me nā abrasives palupalu (olivine, ke one aniani, ka slag) e ʻoki mālie ana a hoʻopau i ke kaomi wai.
• ʻAʻole paʻakikī loa e like me ka alumini oxide (Al₂O₃) a i ʻole silicon carbide (SiC). Hoʻopau nā mea abrasives Superhard i nā paipu hui, e kālele ana i nā nozzles a ʻokiʻoki i nā poʻo me ka wikiwiki loa—hiki iā lākou ke hoʻopōkole i ke ola lawelawe nozzle a hiki i ka 90% vs garnet, e hoʻonui ana i nā kumukūʻai hoʻololi ʻāpana ʻokoʻa kiʻekiʻe.
• Kūpono ʻo Garnet i ka mea kūpono: ka mana ʻoki ikaika + ka hoʻohana kūpono ʻana i nā lako e hoʻohaʻahaʻa i nā lilo mālama mīkini no ka wā lōʻihi.
• 2. ʻO ke kūpaʻa kūpono a me ke ʻano palaoa semi-friable
• He kūpaʻa haʻihaʻi koʻikoʻi ko nā hua garnet (semi-friable). Ke kuʻi ʻia nā ʻāpana hana ma ke kaomi kiʻekiʻe loa, haki nā hua ma nā haki conchoidal e hōʻike mau i nā ʻaoʻao ʻokiʻoki angular ʻoi hou ma loko o ke kahawai jet.
• Hoʻopili koke nā mea abrasive palupalu i lepo maikaʻi ma hope o ka pā ʻana, e nalowale koke ana ka hiki ke ʻoki a koi aku i ka hoʻohana ʻana i ka abrasive kiʻekiʻe.
• Noho paʻa nā mea abrasive paʻakikī loa me nā ʻaoʻao palalulu, e hopena ana i nā ʻili ʻoki ʻinoʻino a ʻāʻī me nā kaha hohonu.
• Mālama ʻo Garnet i ka hana ʻoki mau me ka liʻiliʻi o ka nui o ka hānai one, e mālama ana i ke kumukūʻai abrasive no kēlā me kēia ʻoki.

• 3. Ka nui kūpono (~4.0 g/cm³)

  ʻO kona nui he 4 mau manawa ke kaumaha ma mua o ka wai, ʻo ia ka lakio nui-a-leo kūpono no nā ʻōnaehana AWJ

  Kaumaha loa e loaʻa ai ka ikehu kinetic lawa ke hoʻolalelale ʻia e ka jet wai kiʻekiʻe e ʻoki pono i nā mea paʻakikī.

• ʻAʻole paʻa loa e hiki ʻole ai ke hui like ʻana i loko o ke kahawai a hana i ka ʻoki like ʻole a i ʻole ka pale ʻana o ka jet. ʻAʻole hiki i nā mea abrasives haʻahaʻa ke hoʻoili i ka ikaika hopena kūpono, e alakaʻi ana i ka ʻoki lohi a me nā ʻaoʻao ʻino.
• 
• 4. ʻAno ʻāpana Sub-Angular kūlohelohe no ka maikaʻi ʻoki kiʻekiʻe
• He ʻoi a ʻaʻole like ke ʻano o nā hua garnet maʻemaʻe:
• Hoʻopuka i nā ʻaoʻao ʻoki laumania loa, ʻaʻohe ʻōhū me ka laulā kerf liʻiliʻi; ʻaʻole pono pinepine ka wili/polishing lua.
• ʻO nā koho ʻē aʻe e like me nā momi aniani poepoe e hana wale i ka polishing ʻili me ka ʻole o ka mana ʻoki hohonu; hoʻopuka nā mea abrasives slag i ke komo kaumaha a me nā ʻōpala ʻili ma nā ʻāpana i pau.
• Loaʻa ka laulā o ka ʻupena (60# / 80# / 100#): ʻili ʻāwili no ka ʻoki wikiwiki ʻana i ka metala/pōhaku mānoanoa, ʻili maikaʻi no ka papa lahilahi pololei, ke aniani a me ka ʻoki ʻana i nā ʻano paʻakikī.
  

  5. Haʻahaʻa ka hoʻohana ʻana i nā lako a me ka emi ʻana o ke kumukūʻai hana holoʻokoʻa

  ʻO kēia kekahi o nā pono kālepa nui loa o ka garnet:

• ʻO ka ʻinoʻino ʻana o nā mea hoʻopau koʻikoʻi me ka lohi loa: ke kāwili ʻana i nā ʻōmole, nā nozzles makamae, nā poʻo ʻokiʻoki, nā pamu a me nā pipeline vs. nā mea abrasives paʻakikī loa synthetic.
• ʻOi aku ka haʻahaʻa o ka hoʻohana ʻana i ka abrasive no kēlā me kēia ʻāpana mea i ʻoki ʻia; ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka garnet maoli no kēlā me kēia tona ma mua o ka alumini oxide a i ʻole ka silicon carbide.
• ʻEmi ka manawa hoʻomaha no ka hoʻololi ʻana i ka nozzle/tube, e hoʻonui ana i ka hoʻohana ʻana o ka mīkini a me ka holoʻokoʻa o ka hana.
• He inert kemika, ʻaʻole reactive me nā mea ʻoki maʻamau a pau (nā metala ferrous/non-ferrous, kinikini, granite, foam, carbon fiber, aniani, rubber) a kūlike ʻole i ke kahe wai kiʻekiʻe
• ʻAʻohe hoʻoluʻu kemika, hoʻokeʻokeʻo a i ʻole haumia ʻili ma luna o nā ʻāpana hana i hoʻopau ʻia, koʻikoʻi no ka ʻoki ʻana i nā ʻāpana aerospace, ka ʻai a me ka lāʻau lapaʻau.
• Kūpaʻa i ka ʻakika a me ka alkali, kūpono no ka ʻoki ʻana i nā mea hao kūikawā a me nā mea kūpaʻa i ka ʻino.
• ʻO ka mineral i ʻeli kūlohelohe ʻia me ka silica manuahi haʻahaʻa loa, e hoʻopau ana i nā pilikia olakino silicosis e lawe mai ana i ke one silica i nā mea hoʻohana.
• Hoʻopuka i ka lepo liʻiliʻi loa i ka lewa i ka wā ʻoki ma mua o ka slag, olivine a i ʻole nā ​​​​mea abrasives pōhaku i kuʻi ʻia, e hoʻomaʻalahi ana i ka unuhi lepo a me nā ukana ʻōnaehana ea.
• ʻAʻohe ʻona, ʻaʻohe metala kaumaha; hiki ke hana hou ʻia ka slurry garnet i hoʻohana ʻia (kānana hou ʻia no ka ʻoki lua/pahū ʻana) a i ʻole hoʻohana hou ʻia ma ke ʻano he mea hoʻopiha aggregate no ka asphalt, concrete a me nā mea kūkulu hale me ka ʻole o nā uku hoʻolei ʻōpala weliweli.
• 

• 6. Paʻa Kemika Maikaʻi Loa a me ka Hoʻohālikelike Mea Laulā

  7. Kahi Hana Palekana, Maikaʻi i ka Lepo a Palekana

  8. Hiki ke hana hou ʻia

  Hiki ke kānana ʻia, holoi ʻia, a hoʻokaʻawale hou ʻia ka slurry garnet i hoʻohana ʻia no ka hoʻohana hou ʻana i ka ʻoki ʻana me ka pololei haʻahaʻa a i ʻole ka pahū ʻana i ka ʻili, e hōʻemi hou ana i ke kumukūʻai o nā mea a me ka hoʻopuka ʻana i nā ʻōpala—he pōmaikaʻi hiki ʻole ke loaʻa no nā abrasives synthetic hoʻolei ʻia.

  Hoʻohālikelike wikiwiki me nā Abrasives maʻamau ʻē aʻe

  Hōʻuluʻulu manaʻo

  ʻOi aku ka maikaʻi o ke one Garnet ma mua o nā hoa paio āpau no ka mea ke kaulike nei i ka pono o ka ʻoki ʻana, ka pololei o ka ʻili, ke ola lawelawe mīkini, ke kumukūʻai holo a me ka palekana o ke kaiapuni i ka manawa hoʻokahi—ʻaʻohe mea abrasive hoʻokahi e hiki ke hāʻawi i kēia hana holoʻokoʻa, e lilo ia i mea maʻamau no nā hale hana ʻokiʻoki waterjet honua.
