Hoʻoponopono i ka hana wili ʻana o nā huila wili ma o ka granularity hui ʻia o nā abrasives

ʻO ka wili ʻana he kaʻina hana e hoʻohana ʻia ai kahi huila wili abrasive (GS, e like me ke kiʻi. Hoʻokumu ʻia ka huila wili me nā abrasives, binding agent, fillers and pores, etc. I loko o ia mea, hoʻokani ka abrasive i ke ʻano o ka ʻoki ʻana i ka wā o ka hana wili. ʻO ka paʻakikī, ka ikaika, nā ʻano haʻihaʻi, ka geometry o ka abrasive he hopena koʻikoʻi i ka hana wili (ka mana wili, ka pono o ka ʻili o ka mea hana mīkini, a pēlā aku) o ka huila wili [2, 3].

Fig. 1.ʻO nā huila wili maʻamau me ka granularity hui ʻia o nā abrasives.

Ua ho'āʻoʻia ka ikaika o ka zirconia alumina (ZA) me ka granularity o F14 ~ F30. Ua māhele ʻia nā mea abrasive o F16 a i ʻole F30 ma GS i hoʻomākaukau ʻia i ʻelima mau māka mai ke kiʻekiʻe a i ka haʻahaʻa: ultrahigh (UH), kiʻekiʻe (H), waena (M), haʻahaʻa (L), a haʻahaʻa loa (EL). Ua ʻike ʻia ʻo ka Weibull paʻi ikaika o F14, F16 a me F30 o ZA he 198.5 MPa, 308.0 MPa a me 410.6 MPa, e hōʻike ana ua ulu ka ikaika o ZA me ka emi ʻana o ka nui abrasive grit. ʻO ka modulus Weibull nuimhōʻike i kahi ʻokoʻa liʻiliʻi ma waena o nā ʻāpana i hoʻāʻo ʻia [4-6]. ʻO kamUa emi ka waiwai me ka emi ʻana o ka nui abrasives grit, e hōʻike ana ua ʻoi aku ka nui o ka ʻokoʻa ma waena o nā abrasive i hoʻāʻo ʻia me ka emi ʻana o ka abrasive grit [7, 8]. Ma muli o ka mau o nā hemahema o ka abrasive, ʻoi aku ka liʻiliʻi o nā hemahema a me ka ikaika kiʻekiʻe o nā abrasive liʻiliʻi, no laila ua ʻoi aku ka paʻakikī o ka haki ʻana i nā abrasive maikaʻi.

Fig.2. ʻO ke koʻikoʻi ʻano Weibulls₀a me ka modulus Weibullmno nā granularities like ʻole o ZA.

Ua hoʻomohala ʻia ke kumu hoʻohālike abrasive piha o ke kaʻina hana lawelawe kūpono [9], e like me ka mea i hōʻike ʻia ma ka Fig. 3. Ma lalo o nā kūlana kūpono, he kiʻekiʻe ka hoʻohana ʻana o ka abrasive a hōʻike ka GS i kahi hana wili maikaʻi [3]. Ma lalo o ka ukana wili i hāʻawi ʻia a me ka ikaika o ka mea hoʻopaʻa paʻa, ua hoʻololi ʻia nā mīkini lole nui mai ka lole attrition a me ka micro-facture no ka F16 a hiki i ka lole attrition a huki ʻia no ka F30 nona ka ʻokoʻa o ka ikaika abrasive [10,11]. ʻO ka hoʻokomo ʻana i ka hoʻohaʻahaʻa ʻana i ka GS a me ka hoʻomaʻamaʻa ʻana i ka huki ʻana i hiki ke hoʻokō i kahi kūlana equilibrium, no laila e hoʻoikaika nui ai i ka mana wili [9]. No ka hoʻomohala hou ʻana o ka GS, pono e hoʻoponopono ʻia a hoʻoponopono ʻia ka ikaika o ka abrasive, ka ikaika o ka mea hoʻopaʻa a me ka ukana wili, a me ka hoʻololi ʻana o nā mīkini abrasives.

Fig.3.ʻO ke kaʻina hana lawelawe kūpono o kahi abrasive

ʻOiai ua hoʻohuli ʻia ka hana wili o GS e nā kumu he nui, e like me ka ikaika abrasive crushing, binding agent strength, grinding ukana, abrasive cut behaviors, grinding condition, etc.
