Hiki i ke corundum ʻeleʻele ke pani i ke corundum keʻokeʻo i nā mea abrasives a me nā mea wili? ——Nā Nīnau a me nā Pane ʻIke
Q1: He aha nā corundum ʻeleʻele a me nā corundum keʻokeʻo?
ʻO ke korundum ʻeleʻelehe mea hoʻoheheʻe i hana ʻia me ka bauxite ma ke ʻano he mea maka nui a hoʻoheheʻe ʻia i ka mahana kiʻekiʻe. ʻO kāna ʻāpana nuiʻokikene alumini(Al₂O₃), me kahi ʻike o kahi 94% a ʻoi aku paha, a loaʻa iā ia kahi liʻiliʻi o ka hao oxide a me ka silicon oxide. He mea hoʻomaʻemaʻe kiʻekiʻe ka corundum keʻokeʻo, a ʻo kāna ʻāpana nui he alumini oxide hoʻi, akā me ka maʻemaʻe kiʻekiʻe (ma kahi o 99%) a ʻaneʻane ʻaʻohe haumia.
Q2: He aha ka ʻokoʻa ma waena o ka corundum ʻeleʻele a me ka corundum keʻokeʻo ma ka paʻakikī a me ka toughness?
Paʻakikī: ʻOi aku ka paʻakikī o ka corundum keʻokeʻo ma mua ocorundum ʻeleʻele, no laila he kūpono ia no ka hana ʻana i nā mea paʻakikī kiʻekiʻe. Paʻakikī: ʻOi aku ka paʻakikī o ka corundum ʻeleʻele ma mua o ka corundum keʻokeʻo, a kūpono ia no nā hiʻohiʻona me nā koi kū'ē i ka hopena kiʻekiʻe e like me ka wili ʻino a i ʻole ka wili kaumaha.
Q3: He aha nā wahi hoʻohana nui o ka corundum ʻeleʻele?
Ma muli o kona paʻakikī kiʻekiʻe a me ka paʻakikī kaulike, hoʻohana nui ʻia ka corundum ʻeleʻele i: ka ikaika kiʻekiʻewili ʻananā hiʻohiʻona e like me ka wili ʻana i nā mea ʻino a me ka wili kaumaha. Ka hana ʻana i nā mea me ka paʻakikī kūpono, e like me ke kila, nā mea i hoʻoheheʻe ʻia, a me ka lāʻau. Ka wili ʻana a me ka hoʻopāpā ʻana i ke one, ʻoiai ka wili ʻana i nā mea ʻino.
Q4: He aha nā hoʻohana maʻamau o ka corundum keʻokeʻo?
Ma muli o kona paʻakikī kiʻekiʻe a me ka maʻemaʻe kiʻekiʻe, hoʻohana pinepine ʻia ka corundum keʻokeʻo no: ka wili pololei a me ka poli ʻana, e like me ka hana ʻana i nā metala paʻakikī kiʻekiʻe a me ke kila kila. Ka hana ʻana i nā ʻāpana uila a me nā keramika me nā koi ʻili kiʻekiʻe. Nā kahua hana kiʻekiʻe e like me nā mea lapaʻau a me nā mea hana optical.
Q5: I nā hihia hea e hiki ai i ka corundum ʻeleʻele ke pani i ka corundum keʻokeʻo?
Nā hiʻohiʻona kahi e hiki ai i ka corundum brown ke panicorundum keʻokeʻoe komo pū me: haʻahaʻa ka paʻakikī o ka mea i hana ʻia, a ʻaʻole pono ke kiʻekiʻe loa ka paʻakikī abrasive. ʻAʻole kiʻekiʻe nā koi pololei o ka hana ʻana, e like me ka wili ʻana i ka ʻili a i ʻole ka deburring. Ke kaupalena ʻia nā kumukūʻai waiwai, hiki i ka hoʻohana ʻana i ka corundum ʻeleʻele ke hōʻemi nui i nā lilo.
Q6: I nā hihia hea e hiki ʻole ai ke pani ʻia ke corundum keʻokeʻo e ka corundum ʻeleʻele?
ʻO nā kūlana kahi i hiki ʻole ai ke pani ʻia ka corundum keʻokeʻo e ka corundum ʻeleʻele: ka hana pololei ʻana o nā mea paʻakikī kiʻekiʻe, e like me ke kila kalapona kiʻekiʻe a me ke kila kila. Nā hiʻohiʻona hana me nā koi ʻili kiʻekiʻe loa, e like me ka poli ʻana o ke aniani optical. Nā noi i pili i nā haumia abrasive, e like me nā lako lapaʻau a i ʻole ka hana semiconductor.
Q7: He aha ka ʻokoʻa o ke kumukūʻai ma waena o ka corundum ʻeleʻele a me ka corundum keʻokeʻo?
ʻO nā mea maka nui o ka corundum ʻeleʻele a me ka corundum keʻokeʻo he pōhaku alumini; akā ma muli o nā ʻano hana like ʻole, ʻoi aku ka haʻahaʻa o ke kumukūʻai hana o ka corundum ʻeleʻele, no laila ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka corundum keʻokeʻo. No nā papahana me nā kālā palena, ʻoi aku ka maikaʻi o ke koho ʻana i ka corundum ʻeleʻele.
Q8: I ka hōʻuluʻulu manaʻo, pehea e koho ai i ka abrasive kūpono?
Pono e hoʻoholo ʻia ke koho ʻana o ka corundum ʻeleʻele a i ʻole ka corundum keʻokeʻo e like me nā pono kikoʻī:
Inā ʻo kāu mau pono hana e wili ai a i ʻole ka kaohi ʻana i ke kumukūʻai, ua ʻōlelo ʻia e hoʻohana i ka corundum ʻeleʻele. Inā kiʻekiʻe nā koi pololei o ka hana ʻana a he metala ka mea hana me ka paʻakikī kiʻekiʻe a i ʻole nā ʻāpana kikoʻī, pono e koho ʻia ka corundum keʻokeʻo. Ma ka nānā pono ʻana i nā ʻano o nā mea ʻelua, hiki iā ʻoe ke loaʻa ke kaulike maikaʻi loa ma waena o ka hana a me ke kumukūʻai. Inā he mau nīnau kāu, hiki iā ʻoe ke kūkākūkā hou aku i nā loea e like me ke ʻano o ka noi maoli.
