He aha nā pōmaikaʻi o nā kahua hoʻāʻo granite i hoʻohālikelike ʻia me ka pōhaku maʻamau?

I nā makahiki i hala iho nei, ua piʻi nui ka hoʻohana ʻana i nā kahua nānā granite a me nā mea hana ana, e pani mālie ana i nā ana hao kuʻuna ma nā ʻano he nui. ʻO ke kumu nui o kēia, ʻo ia ka hiki ke hoʻololi i ka granite i nā wahi hana paʻakikī ma ka pūnaewele a me kona hiki ke mālama i ka pololei kiʻekiʻe i ka hala ʻana o ka manawa. ʻAʻole ia e hōʻoia pono i ka pololei i ka wā o ka hana ʻana a me ka hoʻāʻo ʻana, akā hoʻomaikaʻi pū i ka maikaʻi o ka huahana i hoʻopau ʻia. ʻOi aku ka paʻakikī o nā kahua nānā granite me ke kila i hoʻomaʻemaʻe ʻia, a ʻoi aku ka pololei o ko lākou ʻili ma mua o nā mea maʻamau ʻē aʻe.

Hana ʻia mai ka granite ʻeleʻele kūlohelohe kiʻekiʻe, ua hana lima ʻia nā kahua nānā granite me ka hana lima ponoʻī a me ka hoʻopau pinepine ʻana, e hopena ana i kahi ʻili laumania, kahi ʻano paʻa a like, a me ke kūpaʻa maikaʻi loa. He paʻakikī a ikaika lākou, a he kūpaʻa i ka popo, kūpaʻa i ka waikawa a me ka alkali, ʻaʻole magnetic, ʻaʻole e pala, a kūpaʻa loa i ke komo ʻana. Mālama lākou i ke kūpaʻa i ka mahana o ka lumi a ma lalo o nā ukana kaumaha, e lilo ia i mau mea hana ana kuhikuhi pololei kūpono a hoʻohana nui ʻia no ka calibrating i ka pololei o nā mea hoʻāʻo, nā mea hana pololei, a me nā ʻāpana mechanical. ʻOi loa i nā noi ana pololei kiʻekiʻe, ʻoi aku ka maikaʻi o nā kahua granite ma mua o nā papa hao i hoʻolei ʻia.

Ke hoʻohālikelike ʻia me ka pōhaku maʻamau, hāʻawi nā kahua nānā granite i nā pono penei:

ʻAʻole hoʻololi ʻia: Hāʻawi lākou i ka paʻakikī koʻikoʻi, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa wela kiʻekiʻe.

Paʻa kino: He ʻano paʻa a like ko lākou, e hopena ana i nā ʻūlū ma ka ʻili i ka wā e pā ʻia ai, ʻaʻole ia e hoʻopilikia i ka pololei o ka ʻili. He maʻalahi lākou e mālama a mālama i ka pololei i ka hala ʻana o ka manawa, kū i ka popo, anti-magnetic, a insulated.

ʻO ka ʻelemakule kūlohelohe: Ma hope o nā miliona mau makahiki o ka ʻelemakule kūlohelohe, ua hoʻokuʻu loa ʻia nā pilikia kūloko, e hopena ana i kahi coefficient hoʻonui linear haʻahaʻa loa, rigidity maikaʻi loa, a me ke kū'ē ʻana i ka deformation.

Ke kūpaʻa ʻana i ka ʻino: He kūpaʻa lākou i ka ʻino waikawa a me ka alkali, ʻaʻole pono e aila ʻia, a he kūpaʻa i ka lepo, e maʻalahi ai ka mālama ʻana a e hōʻoiaʻiʻo ana i kahi ola lawelawe lōʻihi.

Ana paʻa: He kūpaʻa lākou i ke kahakaha ʻia a ʻaʻole i kaupalena ʻia e nā wahi mahana mau, e mālama ana i ka pololei o ke ana ʻana ma ka mahana o ka lumi.

ʻAʻohe makeneka: Neʻe mālie lākou i ka wā o ke ana ʻana me ke kūpaʻa ʻole a ʻaʻole i hoʻopilikia ʻia e ka makū.

Mahalo i kēia mau waiwai kiʻekiʻe, ua lilo nā kahua nānā granite i mea hana pono ʻole i ke ana pololei o kēia au a me ka kaohi maikaʻi.
