ʻO ka papa ʻili Granite Calibration-Grade no ka hoʻohana ʻana i ka Metrology

ʻO ka papa pōhaku granite he mea ana e ana pono ai i hana ʻia mai ka granite maoli, i hoʻolālā ʻia no ka hoʻohana ʻana i ka nānā ʻana, calibration, a me ka hana hoʻonohonoho e pili ana i nā mea kani, nā mea hana pololei, a me nā ʻāpana mechanical. Me ke kūpaʻa dimensional maikaʻi loa a me ka pale ʻana i ka lole, hoʻohana nui ʻia ia i ka mana maikaʻi a me nā kaiapuni metrology. Hoʻohālikelike ʻia me nā pā hao, hāʻawi nā papa granite i ka hana ʻoi aku ka maikaʻi no nā noi kiʻekiʻe.

Nā mea nui a me nā pono:

1. Paʻa pololei a me ka mālama maʻalahi
   ʻO ka hoʻolālā paʻa, ka ʻili maʻemaʻe, ke kūpaʻa maikaʻi o ka lole, a me ka haʻahaʻa haʻahaʻa o ka ʻili e hōʻoia i ka pololei o ka wā lōʻihi a me ka mālama liʻiliʻi.

2. Maikaʻi Kahiko & Stress-Free Material
   Hoʻokumu ʻia ma luna o nā miliona mau makahiki, ua hoʻokuʻu maoli ka granite i nā koʻikoʻi kūloko, ka hopena i ke kūpaʻa waiwai kiʻekiʻe a ʻaʻohe deformation i ka manawa.

3. Kū'ē i ka Corrosion, Acid, a me Magnetism
   ʻAʻole magnetik ka Granite a kūpaʻa loa i ka corrosion kemika, kūpono ia no ka koi ʻana i nā wahi hana.

4. ʻAʻohe ʻele a me ka maʻu
   ʻAʻole like me ka hao hoʻolei, ʻaʻole ʻeleʻele ka granite a koi ʻole i nā lāʻau anti-corrosion kūikawā. He mea maʻalahi ke hoʻomaʻemaʻe a mālama i nā kūlana humid.

5. Hoʻonui Thermal Haʻahaʻa
   He haʻahaʻa ka helu hoʻonui laina, e hōʻemi ana i ka hopena o ka hoʻololi ʻana o ka mahana ma nā hopena ana.

6. Paʻa kūʻē i ka pōʻino
   Ke hoʻopā ʻia a ʻānai ʻia, hana ʻia nā lua liʻiliʻi wale nō ma kahi o nā burr a i ʻole nā kihi i hāpai ʻia, e mālama ana i ka pololei o ke ana ʻana.
