Nā ʻano o ka pōhaku maoli
Ke kūpale hau
ʻOi aku ka paʻakikī o ka pōhaku anuanu i ka hau, ʻoi loa i ke anuanu ʻākau, ke koho ʻana o nā mea hoʻohana pōhaku kūlohelohe, ʻaʻole nani wale ia, a he 20 mau kekelē Celsius, ʻaʻole e paʻa.
Ke kūpaʻa i ke kaomi
ʻO nā mea pōhaku kūlohelohe ka mea kūkulu me ke kaomi kūpaʻa ikaika i ka mākeke, e like me ka lehulehu. Ke kūʻai ʻana i nā mea pōhaku kūlohelohe, pono e ʻike i kona nui. E ʻokoʻa ka ikaika compressive o nā mea pōhaku ma muli o nā kumu e like me ka likelika o ka haku ʻana o ka mineral, ka mānoanoa o ka aniani, nā mea hoʻowahāwahā ʻia, kahi e hoʻouka ai, ka hopena o ka ukana a me ka huina o ka huina. Kūlike like nā mea ʻē aʻe, kahi mea lahilahi kahi i maʻa mau nā kinikini crystalline a pili i kekahi i kekahi me kahi kiʻekiʻe kiʻekiʻe.
Kūʻē ahi
ʻOi aku ka ikaika o ka hana fireproof o nā mea pōhaku kūlohelohe, hiki ke halihali i ka mahana kiʻekiʻe ma luna o 600 ℃ maʻamau. Akā he aha ka mea e pono ai ka nānā ʻana, ʻano like nā mea pōhaku kūlohelohe, ʻokoʻa ia i ke ahi ʻokoʻa, hāʻule kekahi mea pōhaku i ka hana wela kiʻekiʻe, hana i ka palaho kemikola.
1. Gypsum: decomposition ma luna o 107 ℃.
2. Limestone a me ke kinikini: decomposition ma nā mahana i ʻoi aku ma mua o 910 ℃.
Pohaku: pāhaʻi kaulike wela ma muli o ka hoʻohui mineral ma 600 ℃.
Ma muli o ka hoʻohana ʻia ʻana o ka pōhaku i mālama ʻia ka hale nui o ka hale pule ʻo Notre Dame ma Palisa i ke ahi.
Ola ka pōhaku, e hanu nā lua liʻiliʻi e like me nā ʻili o ka ʻili, ka hopena o ke komo ʻana i ka wai, ka omo ʻana i ke kani a me ka hoʻōlohe kani, i ʻoluʻolu a maikaʻi ke kino o ke kanaka.
Mālama ʻo "Jade i ka poʻe, a hānai ka poʻe i ka jade" ke aniani mālama olakino o Kina no nā makahiki he mau kaukani, a hōʻike pū kekahi hoʻi he pili ka noho ʻana o nā mea āpau i ke ao holoʻokoʻa. ʻO Jade ka mahele o ka pōhaku, loaʻa i kēlā me kēia pōhaku kahi ʻike jade, ʻaʻole hiki ke hoʻokaʻawale ʻia ke ola kanaka mai ke kūlohelohe, ka pōhaku ma ke ʻano he mea hoʻonaninani e pani i ka pilina ma waena o ka poʻe a me ke kūlohelohe. Hoʻopaʻa ka puke compendium o nā taleni i ka hopena o nā mea pōhaku maoli i ka hoʻoulu ʻana i ʻelima mau kino zang a me ke kōkua ʻana i nā uaua koko. ʻO ka coral, aniani a me nā pōhaku semi-waiwai ʻē aʻe ke kuleana o ka pale ʻana i nā iwi a me ke kaulike ʻana i ka ph o ke kino o ke kanaka.
ʻO ka pōhaku ka hana o ka mālama wela a me ka mālama ʻana i ka ikehu. Mai ka wā kahiko a hiki i kēia manawa, hoʻohana ʻia nā pola pōhaku i nā pā meaʻai e pono ai e mālama i ka wela kiʻekiʻe. I ʻEulopa, ua hoʻohana ʻia ka pōhaku no ka hoʻonaninani hale no nā makahiki he mau makahiki i hala
ʻO nā mea pōhaku he huahana pono kūkulu hale, ʻo ia wale nō nā huahana kūkulu hale i hoʻokuʻu ʻia mai ka nānā ʻana, no "ka pōhaku radioactive pōhaku e like me ka radiation, pili i nā ʻoihana mea hana o ka hoʻokūkū kaulike ʻole, ke ʻano o ka alakaʻi hewa, ka hui pōhaku Kina, ka nānā ʻana o ka pono aupuni a me ka nānā ʻana. ke kikowaena, ke kōmike loea standardization pōhaku lāhui e like me ka 2013 i hui pū ʻia i hoʻolaha e pili ana i nā huahana kinikini me ka hōʻeha ʻole i ke kino o ke kanaka.
ʻO ka Pōhaku nā mea hoʻonaninani olakino a maikaʻi loa i ka nohona, pōhaku kūlohelohe i kūlohelohe, hana ʻia i ke kūlohelohe, e like me nā pua a me nā kumulāʻau i ka nui, ʻaʻohe hopena o nā mea radioactive i ke olakino kanaka.
ʻO nā hana mining pōhaku kūlohelohe o kēia manawa, ua haʻalele loa i ka pohā ʻana o ka pauda a me nā mea kūlohelohe ʻē aʻe i ka hana o ka ʻenehana, "mining mining" ʻenehana a me ka paipai ʻana, hoʻomaikaʻi maikaʻi i ka uku mining a me ka hoʻohana ʻana o kaʻu mau kumuwaiwai, akā e hōʻino nō hoʻi ia i ka nohona kūlohelohe. i ka palena iki.CCTV kahawai kālā i loko o ka papahana "2016 home mea hoʻonani alakaʻi alakaʻi" ua hana i nā ana a me nā hoʻokolohua, ma hope o ka hoʻāʻo ʻana ua ʻike ʻia ka marble kūlohelohe i hoʻouna ʻia no ka radiation radiation ma lalo o ka lāʻau, sima, ʻo ia nā mea radiation i haʻahaʻa loa o ka honua. , no ka papa 'āina A (' ohana kaiapuni pale) nā pono hana. E nānā ʻole, ʻo ka pāhawewe o nā kumuwaiwai pōhaku ka ikehu e hoʻokuʻu i ke kumu o ka lani a me ka honua, ʻo kēia ka ikehu e hāʻawi ai ke kūlohelohe i ke olakino olakino.
ʻOiai ʻaʻole hiki i ka pōhaku ke ʻōlelo, akā hiki ke ʻike maka i nā hoʻololi o ke ola, hoʻomālamalama ka civili civilisation, e waiho ana i ka poʻe me ka waiwai pau ʻole, ka hoihoi a me ka hoʻomana ʻana i ka pōhaku maoli, mālama i kēlā me kēia ʻoihana pōhaku.
