ʻO ka hoʻonā anti-corrosion no ke kumu o ka shaft optical ana mea hana: ʻO ka pōmaikaʻi hope loa o ka granite i nā wahi humid.

Ma ke kahua o ke ana pololei, he mea koʻikoʻi nā mea ana ʻana no nā shafts i ka hōʻoia ʻana i ka pololei a me ke ʻano o nā ʻāpana shaft. ʻO ke kūpaʻa a me ka pale ʻana i ka corrosion o ko lākou mau kumu i nā wahi haʻahaʻa e pili pono i ka pololei o nā hopena ana a me ke ola lawelawe o nā mea hana. ʻO ke alo i nā kaiapuni paʻakikī me ka haʻahaʻa haʻahaʻa e like me nā hale hana ʻoihana a me nā wahi kahakai, nā kumu granite, me kā lākou mau waiwai kūʻokoʻa a me nā pono anti-corrosion, ua lilo i mea koho maikaʻi loa no nā mea ana optical no nā shafts.

ʻO nā pilikia o nā kaiapuni pulu i ke kumu o nā mea ana
He pilikia nui ke kaiapuni haʻahaʻa e ke kumu o nā mea ana ʻano optical shaft. ʻAʻole e hoʻokuʻu wale ka makū i ka lewa ma ka ʻili o ke kumu e hana i kahi kiʻi wai, akā hiki ke komo i loko o ka mea. No nā kumu metala, e like me ka hao a i ʻole nā ​​kumu kila, hiki ke maʻalahi kahi ʻano haʻahaʻa i ka oxidation a me ka ʻōpala, e alakaʻi ana i ka ʻino a me ka ʻili ʻana o ka ʻili kumu, a laila e hoʻopili i ka pololei o ka hoʻonohonoho ʻana a me ka paʻa o ka mea ana. I kēia manawa, hiki i ka ʻōpala i hana ʻia e ka ʻōpala ke komo i loko o nā ʻāpana pololei o ka mea ana, e hōʻeha ai a hoʻopaʻa i nā ʻāpana, e hoʻopilikia nui i ka pololei o ke ana a me ka hana maʻamau o nā mea hana. Eia kekahi, hiki i ka hoʻonui ʻana i ka wela a me ka hopena i ka hoʻololi ʻana i ka haʻahaʻa ke alakaʻi i nā hoʻololi liʻiliʻi i ka nui o ke kumu, e hoʻoneʻe ai ke kuhikuhi ʻana i ke ana ʻana a me ka hopena i nā hewa ana i hiki ʻole ke nānā ʻole ʻia.
ʻO ka waiwai anti-corrosion kūlohelohe o ka granite
ʻO Granite, e like me ke ʻano o ka pōhaku maoli, loaʻa iā ia kahi pono o ka anti-corrosion. Hoʻopili paʻa ʻia nā kristal koʻikoʻi kūloko a paʻa a paʻa ke ʻano, e hana ana i kahi pale pale kūlohelohe e pale nui i ke komo ʻana o ka wai. ʻAʻole e like me nā mea metala, ʻaʻole i loaʻa ka granite i nā hopena kemika me nā mea ʻawaʻawa maʻamau a i ʻole alkaline. ʻOiai inā e ʻike ʻia i kahi wahi haʻahaʻa i loaʻa nā kinoea corrosive a i ʻole nā ​​​​wai no ka manawa lōʻihi, hiki iā ia ke mālama i nā waiwai kemika paʻa a ʻaʻole e loaʻa nā pilikia e like me ka corrosion a me ka ʻōpala.

I nā ʻoihana hana mechanical ma nā kahakai, ʻoi aku ka kiʻekiʻe o ka ea i loko o nā hale hana i loko o ka makahiki a loaʻa i kahi nui o ka paʻakai. E hōʻike ana ka mea ana ʻike no nā kumu me nā kumu hao hoʻoheheʻe ʻia i loko o kekahi mau mahina wale nō, a e piʻi mau ana ka hewa ana. ʻO ka mea ana me kahi kumu granite ua noho maʻemaʻe a hou e like me ka wā ma hope o kekahi mau makahiki o ka hoʻohana ʻana, a ua paʻa mau kāna ana ʻana, e hōʻike pono ana i ka hana anti-corrosion koʻikoʻi o ka granite i loko o kahi ʻāina humid.
ʻO nā pono hana piha o nā kumu granite
Ma waho aʻe o kona pale ʻana i ka corrosion maikaʻi loa, ʻoi aku ka nui o nā pono ʻē aʻe o ka base granite, e hāʻawi ana i ka pale piha no ka hana paʻa o ka mea ana o ka shaft optical i loko o kahi wahi humid. He haʻahaʻa loa ka coefficient o ka hoʻonui wela o ka granite, ʻo 5-7 wale nō × 10⁻⁶/℃. Ma lalo o ka hoʻololi ʻana o ka mahana ma muli o ka hoʻololi ʻana o ka haʻahaʻa, ʻaʻole hiki ke hoʻololi i ka dimensional deformation, e hōʻoiaʻiʻo ana i ka paʻa lōʻihi o ka ʻike ana. I kēia manawa, hiki i nā hiʻohiʻona haʻalulu maikaʻi loa o ka granite ke hoʻopaʻa pono i nā haʻalulu o waho. ʻOiai inā loaʻa i nā mea hana ke kani iki ʻana ma muli o ka mana o ka mahu wai i loko o kahi wahi haʻahaʻa, hiki ke hoʻemi koke ʻia ka haʻalulu, e pale aku i ka hoʻopilikia ʻana i ke ana pololei.

Eia kekahi, ma hope o ka hana ultra-precision, hiki i ke kumu granite ke hoʻokō i ka pālahalaha kiʻekiʻe loa, e hāʻawi ana i kahi kuhikuhi hilinaʻi no ke ana kiʻekiʻe o nā ʻāpana shaft. ʻO kona ʻano paʻakikī kiʻekiʻe (Mohs hardness of 6-7) e hana i ka ʻili kumu i ke kūpaʻa maikaʻi loa. ʻOiai me ka hoʻohana pinepine ʻana i kahi wahi haʻahaʻa, ʻaʻole ia e luhi, e hoʻonui i ke ola lawelawe o ka mea ana.

Ma ke kahua o ke ana ʻana o nā ʻōpuʻu me nā koi kikoʻī kiʻekiʻe loa, ʻaʻole hiki ke nānā ʻole ʻia nā pilikia corrosion a me ke kūpaʻa i hoʻokumu ʻia e nā wahi humid. ʻO nā kumu Granite, me kā lākou mau waiwai anti-corrosion kūlohelohe, ka hana kino kūpaʻa a me nā pōmaikaʻi ākea koʻikoʻi, ua lilo i hopena hope loa i kēia mau pilikia. ʻO ke koho ʻana i kahi mea ana optical no nā shafts me kahi kumu granite hiki ke hōʻoia i ka hana hoʻomau a paʻa i kahi ʻano haʻahaʻa, hoʻopuka i ka ʻikepili ana pono a hilinaʻi, a mālama i ka hoʻomohala kiʻekiʻe o nā ʻoihana e like me ka hana mechanical a me ka aerospace.
