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

ʻO ka papa pōhaku granite kahi mea hana kuhikuhi pololei i hana ʻia mai nā mea pōhaku maoli. Hoʻohana nui ʻia ia no ka nānā ʻana i nā mea kani, nā mea hana pololei, a me nā ʻāpana mechanical, e lawelawe ana ma ke ʻano he papa kuhikuhi kūpono i nā noi ana kiʻekiʻe. Ke hoʻohālikelike ʻia me nā pā hao kuʻuna, hāʻawi nā papa ʻāina granite i ka hana ʻoi aku ka maikaʻi ma muli o ko lākou mau waiwai kino.

Pono ʻia ke kākoʻo ʻenehana no ka hana ʻana i nā pā ili Granite

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

   • Maʻiʻo mika <5%

   • ʻO ka modula lohi > 0.6 × 10⁻⁴ kg/cm²

   • ʻO ka hoʻoheheʻe wai <0.25%

   • Ka paakiki > 70 HS

2. ʻenehana hana

   • ʻOki ʻoki a wili ʻia ka mīkini a ukali ʻia e ka lapping manual ma lalo o nā kūlana wela mau e loaʻa ai ka palahalaha kiʻekiʻe.

   • ʻO ka waihoʻoluʻu like ʻole me ka ʻole o nā māwae, pores, inclusions, a i ʻole nā ​​​​hanana wehe.

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

3. Nā Kūlana Pono

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

   • ʻOka ʻili ʻaoʻao: ≤ 10 μm.

   • ʻO ka hoʻomanawanui pololei o nā alo ʻaoʻao: kūlike me GB/T1184 (Papa 12).

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

4. Nā Manaʻo Kūleʻa

   • ʻĀpana haʻawe waena i hoʻolālā ʻia e kū i nā haʻawe i helu ʻia me ka ʻole o nā koina deflection ʻae ʻia.

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

   • ʻAʻole pono e hoʻonui i nā puka wili a i ʻole T-slots (inā makemake ʻia ma nā papa 0-grade a i ʻole 1-grade) ma luna o ka ʻili hana.

Pono e hoʻohana i nā ʻāpana ʻili Granite

1. Ka Pono o ka Ili

   • Pono e noho kaʻawale ka ʻili hana mai nā pōʻino koʻikoʻi e like me nā pores, nā māwae, nā hoʻopili, nā ʻōpala, a i ʻole nā ​​​​hōʻailona ʻōpala.

   • ʻAe ʻia ka ʻoki ʻoki liʻiliʻi a i ʻole nā ​​kihi kihi liʻiliʻi ma nā wahi hana ʻole, akā ʻaʻole ma ka ili ana.

2. Ka lōʻihi
   He kiʻekiʻe ka paʻakikī a me ke kūpaʻa ʻana o nā papa Granite. ʻOiai ma lalo o ka hopena koʻikoʻi, hiki mai nā ʻāpana liʻiliʻi wale nō me ka ʻole o ka hoʻopili ʻana i ka pololei holoʻokoʻa - ʻoi aku ka maikaʻi ma mua o nā ʻāpana kuhikuhi hao a kila paha.

3. Nā Kūlana Hoʻomalu

   • Hōʻalo i ka waiho ʻana i nā ʻāpana kaumaha ma ka pā no ka manawa lōʻihi e pale i ka deformation.

   • E mālama maʻemaʻe ka ʻili hana a me ka ʻole o ka lepo a i ʻole ka aila.

   • E mālama a hoʻohana i ka pā ma kahi maloʻo a paʻa ka mahana, ma kahi mamao aku i nā kūlana corrosive.

I ka hōʻuluʻulu ʻana, hoʻohui ka papa pōhaku granite i ka ikaika kiʻekiʻe, ke kūpaʻa dimensional, a me ke kūpaʻa ʻokoʻa o ka lole, no laila he mea nui ia i ke ana pololei ʻana, nā papa hana mīkini, a me nā laboratories. Me ke kākoʻo ʻenehana kūpono i ka hana ʻana a me nā hana hoʻohana pololei, hiki i nā papa granite ke mālama i ka pololei a me ka lōʻihi ma luna o nā noi lōʻihi.
