Kākoʻo ʻenehana a me nā koi hoʻohana no ka papa ʻili Granite

He mea hana kuhikuhi pololei ka papa ʻili granite i hana ʻia mai nā mea pōhaku maoli. Hoʻohana nui ʻia ia no ka nānā ʻana i nā mea hana, nā mea hana pololei, a me nā ʻāpana mīkini, e lawelawe ana ma ke ʻano he ʻili kuhikuhi kūpono i nā noi ana pololei kiʻekiʻe. Ke hoʻohālikelike ʻia me nā papa hao i hoʻolei ʻia maʻamau, hāʻawi nā papa ʻili granite i ka hana maikaʻi loa ma muli o ko lākou mau waiwai kino kūikawā.

Kākoʻo ʻenehana e pono ai no ka hana ʻana i nā papa ʻili Granite

1. Koho Mea Hana
   Hana ʻia nā papa ʻili Granite mai ka granite kūlohelohe kiʻekiʻe (e like me ka gabbro a i ʻole diabase) me ke ʻano crystalline maikaʻi, ka ʻano mānoanoa, a me ke kūpaʻa maikaʻi loa. ʻO nā koi koʻikoʻi:

   • Ka nui o ka mika < 5%

   • Modulus elastic > 0.6 × 10⁻⁴ kg/cm²

   • Ka omo ʻana o ka wai < 0.25%

   • Paʻakikī > 70 HS

2. ʻenehana hana

   • ʻO ka ʻoki ʻana a me ka wili ʻana me ka mīkini a ukali ʻia e ka ʻūmiʻi lima ʻana ma lalo o nā kūlana mahana mau e hoʻokō ai i ka palahalaha kiʻekiʻe loa.

   • ʻAno like ke kala o ka ʻili me ka ʻole o nā māwae, nā pores, nā inclusion, a i ʻole nā ​​​​​​hale wehe.

   • ʻAʻohe ʻōpala, kuni, a i ʻole nā ​​kīnā e hiki ke hoʻopilikia i ka pololei o ke ana ʻana.

3. Nā Kūlana Pololei

   • ʻO ka ʻoʻoleʻa o ka ʻili (Ra): 0.32–0.63 μm no ka ʻili hana.

   • ʻO ka ʻoʻoleʻa o ka ʻaoʻao: ≤ 10 μm.

   • Ke ahonui perpendicularity o nā ʻaoʻao ʻaoʻao: kūlike me GB/T1184 (Papa 12).

   • Pololei pālahalaha: loaʻa i nā māka 000, 00, 0, a me 1 e like me nā kūlana honua.

4. Nā Manaʻo Kūkulu

   • Wahi halihali ukana waena i hoʻolālā ʻia e kū i nā ukana i helu ʻia me ka ʻole o ka ʻoi aku ma mua o nā waiwai deflection i ʻae ʻia.

   • No nā papa 000 a me 00-papa, ʻaʻole i ʻōlelo ʻia nā lima hāpai e mālama i ka pololei.

   • ʻAʻole pono e hoʻolōʻihi ʻia nā lua wili a i ʻole nā ​​​​​​ʻāpana T (inā makemake ʻia ma nā papa 0-grade a i ʻole 1-grade) ma luna o ka ʻili hana.

Nā Koina Hoʻohana o nā Papa ʻIli Granite

1. Ka Pono o ka ʻIli

   • Pono e kaʻawale ka ʻili hana mai nā kīnā koʻikoʻi e like me nā pores, nā māwae, nā inclusions, nā scratches, a i ʻole nā ​​māka popo.

   • ʻAe ʻia nā ʻoki liʻiliʻi o ka lihi a i ʻole nā ​​​​hemahema liʻiliʻi o ke kihi ma nā wahi hana ʻole, akā, ʻaʻole ma ka ʻili ana.

2. Ka paʻa
   He paʻakikī kiʻekiʻe ko nā papa granite a me ke kūpaʻa i ka ʻaʻahu. ʻOiai ma lalo o ka hopena nui, hiki ke hana ʻia nā ʻāpana liʻiliʻi me ka ʻole o ka hoʻopilikia ʻana i ka pololei holoʻokoʻa—e hoʻolilo ana iā lākou i ʻoi aku ka maikaʻi ma mua o nā ʻāpana kuhikuhi hao a kila paha.

3. Nā Alakaʻi Mālama

   • Mai kau i nā ʻāpana kaumaha ma luna o ka pā no ka wā lōʻihi e pale ai i ka deformation.

   • E mālama i ka ʻili hana i maʻemaʻe a ʻaʻohe lepo a ʻaila paha.

   • E mālama a hoʻohana i ka pā i kahi maloʻo, paʻa i ka mahana, kahi ʻē aʻe mai nā kūlana ʻino.

I ka hōʻuluʻulu manaʻo, hoʻohui ka papa ʻili granite i ka ikaika kiʻekiʻe, ke kūpaʻa o ka dimensional, a me ke kūpaʻa ʻana i ka ʻaʻahu, e lilo ia i mea nui loa i ke ana pololei, nā hale hana mīkini, a me nā keʻena hoʻokolohua. Me ke kākoʻo loea kūpono i ka hana ʻana a me nā hana hoʻohana pololei, hiki i nā papa granite ke mālama i ka pololei a me ke kūpaʻa i nā noi lōʻihi.
