ʻO ka quartzite keʻokeʻo, ʻaʻole e like me nā ʻano ʻē aʻe ʻē aʻe, pono ke nānā ʻia. He wahi wai kiʻekiʻe e pale nui i nā kiʻekiʻe kiʻekiʻe. Hoʻohana pinepine ʻia ka Quartzite no ka kūkulu ʻana i nā ʻauʻau, no laila i kekahi mau kumu i kapa ʻia ʻo ia he ʻano ʻauʻau ʻauʻau. Kēia loa hiki ke loaʻa i nā kūlana kūlohelohe, ʻo ka manawa pinepine ka mea i hoʻokaʻawale ʻia no ke kūkulu hale ʻana.
Hiki i kēia ʻano ʻāpana metamorphic ke loaʻa i nā kukui māmā, ma ka maʻamau hiki ke maʻalahi ke aniani a ʻulaʻula keʻokeʻo paha. He mea nui hoʻi e hoʻomaopopo e loaʻa i nā ʻano hana like ʻole. ʻO ka maʻamau, ʻo kāna mea hoʻokomo e loaʻa i kahi nui o nā haumia o nā pōhaku ʻē aʻe. Hiki ke ʻike i nā mea'āpana kala i ka luhi o ka mea.
Pioʻa wai - quartzite keʻokeʻo
Hoʻohana pinepine ʻia kēia pōhaku i ka hoʻolālā a me ka hoʻokaʻawale ʻana i nā kaukau, no ka mea hiki ke kū i nā loli nui. Akā, ma mua o ka hoʻohana ʻana iā ia, he mea pono ke aʻo maʻa i kona mau waiwai āpau. Hoʻopili i kahi pale wela, ke kuapo keʻokeʻo ka nui o ka refractoriness.
ʻO nā hiʻohiʻona a me ka mechanical o ka quartzite keʻokeʻo
Aia ka pōhaku i ka silicon oxide SiO2, aʻo kona ikaika compressive he 100-400 MPa, me kahi kaulike o 2.6 g / cm3 a me ke ahi kū'ē i 2000 degere Celsius. ʻO ia mau hiʻohiʻona e hiki ai ke hoʻohana ʻia no ke kūkulu ʻana i nā ʻāʻī a me nā huahana ʻē aʻe, a me nā mea i wehe ʻia ke ahi e hana. Ma kona ikaika, he lua ka quartzite wale nō i ka kila a me ka corundum. Hoʻohana pinepine ia i nā kaukau i nā kau ma mua o hoʻokahi makahiki, ma hope o kahi a ke hoʻololi ʻia i kahi hou.
Akā, akā, ʻo ke kumu nui o ka noi ʻana o kēia pōhaku ua hoʻomau ka kūkulu ʻana a me ka hoʻolālā. Ma kāna hoʻohana e hiki ai iā ʻoe ke hoʻomau i ke kūkulu ʻana i ke ua nui, no ka mea, he maikaʻi ʻole ka eme. Eia kekahi, loaʻa nō hoʻi ke kū'ē kūlohelohe kiʻekiʻe. Akā, ke kumu, kaulana loa kēia pōhaku ma muli o ka loaʻa ʻole o ka mākaukau e hōʻili i nā lepili.
