ʻAʻole maʻalahi ka pane. ʻAʻole lanakila nā mea ʻelua ma nā wahi āpau. ʻO ka hoʻomaopopo ʻana i nā waiwai kumu o nā mea hana ana seramika a me granite—a me kahi e ʻoi aku ai kēlā me kēia mea—hiki ke mālama i nā tausani o nā mea hana i nā kumukūʻai hana hou, hoʻolōʻihi i nā manawa calibration, a hāʻawi i nā ʻāpana maikaʻi aʻe i nā mea kūʻai aku.
He aha ka mea e ʻokoʻa ai kēia mau mea
Hoʻomaka ka ʻokoʻa ma ka pae atomika. ʻO nā mea hana ana seramika he mau mea hana ʻenekinia, i hana pinepine ʻia mai ka alumini oxide (Al₂O₃), zirconium oxide (ZrO₂), a i ʻole silicon carbide (SiC). Koho ʻia kēlā me kēia hui no nā ʻano hana kikoʻī a sintered i nā mahana kiʻekiʻe e hana i kahi ʻano paʻa a ʻaʻohe pore. ʻO kēia kaohi hana ʻana ʻo ia hoʻi kēlā me kēia pūʻulu hana e hoʻokō i nā waiwai kūlike, e hiki ai ke hoʻomanawanui paʻa ma nā nui he nui.
ʻO nā mea hana ana Granite, ma ke ʻano ʻē aʻe, mai ke ʻano maoli mai. ʻO ka granite ʻeleʻele a i ʻole diabase i kālai ʻia mai nā ʻano geological kikoʻī e hāʻawi i ka mea maka. ʻOiai aia ka ʻokoʻa kūlohelohe ma waena o nā kumu, ʻo nā ʻenehana hana hou—me ka hoʻomehana wela a me nā pōʻaiapuni hoʻomaha-pilikia—ua hoʻoponopono nui i nā hopohopo koʻikoʻi kūloko i hoʻopilikia i nā mea hana granite mua. Hāʻawi ka ʻano crystalline o ka mea i kāna ʻano damping ʻano.
ʻO kēia ʻokoʻa nui i ke kumu e hoʻohālike i aneane kēlā me kēia ʻano hana ma hope.
ʻO ka Pōmaikaʻi o ka Ceramic: Paʻakikī, Insulation, a me ke Kaumaha Māmā
Hōʻike ka hoʻāʻo paʻakikī Vickers i ke kumu e lanakila ai ka keramika i nā noi palupalu. Loaʻa i nā keramika alumina ka HV 1400-1800, hoʻohālikelike ʻia me ke kila ma HV 600-800 a me ka granite ma kahi o HS 70. ʻOi aku kēlā ma mua o ka pālua o ke kūpaʻa o ka ʻili i ka abrasion i hoʻohālikelike ʻia me ke kila. Ma nā wahi hana kahi e hoʻopili ai nā ana i nā ʻāpana i nā tausani manawa i kēlā me kēia neʻe ʻana, ʻoi aku ka lōʻihi o nā ʻāpana keramika ma mua o ka pono o ka recalibration. Hoʻohui ʻia nā hopena waiwai ma luna o nā makahiki o ka hoʻohana ʻana i kēlā me kēia lā.
ʻO ka modulus a Young o 300–380 GPa e haʻi i kahi moʻolelo like. ʻOi aku ka paʻakikī o ka seramika ma mua o ke kila ma kahi o 1.5 a me ka granite ma kahi o 4–5. Ma lalo o ke kaumaha ana, emi ka hoʻohuli ʻana o nā mea hana seramika a hoʻi pololei i ke ʻano kumu. He mea waiwai nui kēia pono o ka paʻakikī i nā ana dimensional kahi e hoʻokomo ai ka deflection probe i ka hewa ʻōnaehana.
ʻO ke kaumaha paha ka mea e haʻi mai ana i ka moʻolelo kupaianaha loa. Aia ka nui o ka seramika ma kahi o 3.90 g/cm³—ma kahi o ka hapalua o ke kila a me ka hapakolu o ka granite. Hiki i kahi loea hoʻokahi ke hāpai i kahi pā ana keramika e pono ai kahi hoist a crane paha no kahi granite like. Loaʻa ka pōmaikaʻi nui o nā noi ana lawe lima mai kēia ʻano. Hōʻike nā hui lawelawe kahua i ka emi nui ʻana o ka luhi o ka mea hoʻohana i ka wā e hoʻololi ai i nā mea hana seramika, a hoʻomaikaʻi pinepine ka pololei o ke ana ʻana o ke kahua no ka mea hiki i nā loea ke lawelawe pono i nā ana me ka ʻole o ka hakakā ʻana me ke kaumaha.
Hoʻopau nā waiwai uila i ka ʻaoʻao keramika. ʻO ke kū'ē ʻana o ka leo ma mua o 10¹⁴ Ω·cm ʻo ia hoʻi ka insulation uila piha. ʻAʻole hana ka keramika i kahi kahua magnetic, ʻaʻohe alakaʻi o ke au, a ʻaʻohe mea ferrous i loko. No ka hana ʻana i ka semiconductor, ka hana ʻana i nā mea lapaʻau, a me kekahi hana e pili ana i nā ʻāpana uila magnetic sensitive, hoʻopau nā mea hana ana keramika i kahi ʻano holoʻokoʻa o ka hewa ana. Hōʻike nā mīkini ana hoʻonohonoho i lako me nā styli probe keramika i ka emi ʻana o ka thermal drift ma nā ʻano hiki ʻole i nā styli metala ke hoʻohālikelike.
Hoʻohui ka pale ʻana i ka palaho i kahi ʻano ʻē aʻe. Kūʻē nā ʻili seramika i ka hoʻouka ʻia mai aneane nā kemika ʻoihana āpau. ʻO ka waikawa hydrofluoric a me nā alkalis ikaika i nā mahana kiʻekiʻe e hōʻike i nā ʻokoʻa liʻiliʻi. ʻOiai ʻo ka granite e lawelawe pono i nā wahi hana maʻamau, ulu maikaʻi ka seramika i loko o nā lumi maʻemaʻe, nā keʻena hana lāʻau lapaʻau, a me nā hale hana kemika kahi e hoʻohaʻahaʻa mālie ai nā mea hoʻomaʻemaʻe ikaika i nā mea liʻiliʻi. ʻO ka hōʻino ʻana o ka ʻili ma nā mea hana ana e unuhi pololei i ka hewa ana—pale loa ka seramika i kēia ʻano hāʻule.
Pono ka hana wela e kūkākūkā nui ʻia. Me ka coefficient hoʻonui wela o 7–8 ×10⁻⁶/°C, hoʻonui ka keramika ma kahi o ʻelua ka nui o ka granite ma kēlā me kēia kekelē loli mahana. Eia nō naʻe, ke kūpaʻa nei ka hoʻopaʻapaʻa no ka keramika i nā wahi koʻikoʻi. Mālama kekahi mau ʻano keramika i ka hana ma luna o 1000°C, ʻoi aku ma mua o nā mea hao a granite paha. No nā mea kūʻai aku e ana ana i nā ʻāpana ma nā mahana kiʻekiʻe, hāʻawi nā kūlana hoʻoili keramika i kahi hopena kūpono ʻaʻole hiki i ka granite ke hāʻawi.
Hōʻoia nā kūlana ʻoihana i nā ʻano hana seramika. Kuhikuhi ʻo ISO 14704 i nā kaʻina hana hoʻāʻo Flexural Strength, ʻoiai ʻo ISO 6507 e uhi ana i ke ʻano hana ana o ka paʻakikī. Hōʻoia nā palapala hōʻoia calibration NIST-traceable e hoʻokō nā mea hana ana seramika i nā koi metrological like i hoʻopili ʻia i nā mea hana kila a me ka granite kuʻuna.
ʻO ka Pōmaikaʻi o ka Granite: Damping, Paʻa, a me ka Hoʻokele Waiwai
Hōʻike ʻo Granite i kahi moʻolelo ʻokoʻa—hoʻokahi i kākau ʻia ma luna o nā miliona mau makahiki o ka hoʻokumu ʻana o ka honua. ʻO ka hopena he mea me nā ʻano damping kupaianaha. ʻO kahi kumu pohō (damping ratio) o 0.012–0.015 ʻo ia hoʻi ke omo nei ka granite i ka ikehu haʻalulu ma mua o ka keramika a i ʻole ke kila. Ke holo nā mīkini CNC i nā pōʻaiapuni kokoke, ke lūlū ke kaʻa forklift i nā hale papahele, ke holo a pio nā ʻōnaehana HVAC, mālama nā papa ʻili granite i nā ʻili ana i paʻa.
He mea nui loa ka manaʻo kūpono i nā wahi hana maoli. Hiki i kahi papa granite ma kahi papahele hana paʻahana ke hōʻike i nā ʻano ana o 0.5 μm ma lalo o nā kūlana e hoʻokuke ai i nā mea hana keramika i ka oscillation 2-3 μm. No nā mīkini ana hoʻonohonoho a me nā lako hana ʻē aʻe e pili ana i ka haʻalulu, hāʻawi nā kumu granite i ka paʻa passive ʻaʻole hiki i nā ʻōnaehana hoʻokaʻawale hana wale nō ke hoʻohālikelike. Kuhikuhi ka nui o nā mea hana CMM i nā kumu granite ma ke ʻano he lako maʻamau no kēia kumu.
Hahai ke ʻano wela i kahi ʻano like. ʻO ke koina hoʻonui haʻahaʻa o 4.5 × 10⁻⁶/°C e hāʻawi i ka granite i ka paʻa maikaʻi o ka dimensional ma o nā loli mahana. ʻOi aku ka mea nui, hōʻike ka granite i ka inertia thermal kiʻekiʻe. Hoʻolaha mālie nā loli mahana ma o ka nuipa mea, e hōʻemi ana i nā hewa ana transient i ka wā o nā loli wela o ka papahele hale kūʻai. Hiki i kahi papa ʻili granite ke mahana mālie ma o ka neʻe kakahiaka i ka wā e wela ai nā lako, me ka hoʻonui mālie a wānana ʻia e hiki ai i nā mea hana akamai ke uku. Pane wikiwiki nā ʻili seramika i nā loli mahana, e hana ana i ka hiki ke holo wikiwiki.
ʻIke pinepine nā hale hana me ka ʻole o ka mana o ke aniau i ka hana granite ʻoi aku ka maikaʻi ma mua o ka keramika ma lalo o kēia mau kūlana. ʻO nā hale hana mīkini nui me nā kaupaku kiʻekiʻe, nā loli o ka mahana o ke kau, a me nā lako hana wela e hōʻike ana i nā pilikia e hoʻoponopono maikaʻi ʻia e ka granite ma mua o ka hapa nui o nā koho ʻē aʻe. ʻO nā hale hana hana kaʻa, nā hale hana lako kaumaha, a me nā hale hana hana e kuhikuhi pinepine i nā ʻili ana granite no kēia mau kumu.
ʻO nā noʻonoʻo kumukūʻai e makemake nui i ka granite i nā noi ʻano nui. Loaʻa nā mea maka Granite mai nā kumu kūlohelohe he nui, a ua hoʻokumu maikaʻi ʻia nā ʻano hana quarrying. Nā kaʻina hana nonā papa ʻili granite, nā kumu mīkini, a me nā ʻano hana nui like i hoʻomaʻemaʻe ʻia i nā makahiki he ʻumi. Ke piʻi nei ke kumukūʻai o ka hana ʻana i ka seramika ma nā nui nui ma muli o nā palena sintering, nā palena umu, a me nā pilikia hua. ʻO kahi papa ʻili granite e ana ana i hoʻokahi mika kuea paha ke kumukūʻai i kahi hapa o kahi panela seramika like—a ʻo nā panela seramika o kēlā nui ʻaʻole i kūʻai ʻia ma ka hapa nui o nā mākeke.
No nā noi e pono ai nā ʻili kuhikuhi nui a pālahalaha—nā alahaka CMM, nā kahua mīkini CNC nui, nā kumu papa ʻike optical, nā ʻōnaehana gantry—hāʻawi ka granite i ka pololei i ʻae ʻia ma nā kumukūʻai hiki ke loaʻa. Hoʻākāka nā kūlana ISO 8512-2 a me ASME B89.3.7 i nā hoʻomanawanui pālahalaha hiki ke hiki no nā papa ʻili granite, a hoʻokō mau nā mea hana i nā koi i nā ʻano nui kahi i loaʻa ʻole ai nā koho seramika ma ke kālepa.
ʻO ke kaumaha o ka granite e lilo maoli i mea maikaʻi i nā noi paʻa. Ke hoʻokomo ʻia ma kahi kahua i hoʻolālā pono ʻia, e noho mau nā lako granite ma kahi. Hiki ke hoʻomaikaʻi ʻia nā pads hoʻokaʻawale haʻalulu ma lalo o nā kumu granite no ka hoʻouka nui ʻana. ʻO ke kūpaʻa kūlohelohe o kahi hale granite nui e hāʻawi i kahi kuhikuhi ana e hiki ʻole i nā mea māmā ke hoʻokūkū.
