Hoʻohana i ka vermiculite
Hoʻohana ʻia no ka insulation thermal
Loaʻa i ka vermiculite i hoʻonui ʻia nā hiʻohiʻona o ka porous, ke kaumaha māmā a me ka helu hoʻoheheʻe kiʻekiʻe, a ʻoi aku ka maikaʻi no nā mea wela wela (ma lalo o 1000 ℃) a me nā mea pale ahi.Ua puhi ʻia ka papa vermiculite sima ʻumikūmālima kenimika-mānoanoa ma 1000 ℃ no 4-5 mau hola, a ʻo ka mahana ma ke kua he 40 ℃ wale nō.Ua puhi ʻia ka ʻāpana vermiculite mānoanoa ʻehiku kenimika ma kahi wela kiʻekiʻe o 3000 ℃ no ʻelima mau minuke e kahi ʻupena lapalapa ahi.Ua hehee ka ʻaoʻao mua, ʻaʻole i mahana ka lima ma hope.No laila ʻoi aku ia ma mua o nā mea insulation āpau.E like me ka asbestos a me nā huahana diatomite.
Hiki ke hoʻohanaʻia ka vermiculite ma keʻano he mea hoʻoheheʻe wela i nā keʻena wela kiʻekiʻe, e like me nā pōhaku lepo wela, nā papa hoʻoheheʻe wela a me nā pāpale wela i kaʻoihana hoʻoheheʻe.Hiki ke hoʻopaʻa ʻia nā mea hana e pono ai ka insulation thermal me ka pauka vermiculite, nā huahana vermiculite sima (nā pōhaku vermiculite, nā pā vermiculite, nā paipu vermiculite, a me nā mea ʻē aʻe) a i ʻole nā huahana vermiculite asphalt.E like me nā paia, nā hale, nā waihona anu, nā paila, nā paipu mahu, nā paipu wai, nā hale kiaʻi wai, nā kapuahi hoʻololi, nā mea hoʻololi wela, ka mālama ʻana i nā waiwai weliweli, etc.
Hoʻohana ʻia no ka papa hoʻopuʻu kani
Hoʻonui ʻia ka vermiculite ma muli o ka hoʻokumu ʻia ʻana o ka ʻāpana o ka ea maikaʻi, e hana ana i kahi mea insulation porous, i ka wā o ke alapine o 2000C / S, vermiculite mānoanoa 5mm i ka wā o ke kani absorption rate o 63%, kahi mānoanoa o ka vermiculite 6mm i ka wā o ke kani ʻana o 84. % , vermiculite ʻO 90% ka nui o ka hoʻoheheʻe ʻana i ke kani inā 8mm ka mānoanoa pōhaku.
No nā keʻena pale radiation
Hiki i ka vermiculite ke komo i ka radiation.Hiki i ka pā vermiculite i hoʻokomo ʻia i loko o ke keʻena ke hoʻololi i ka pā alakaʻi kumu kūʻai kiʻekiʻe e hoʻomoʻa i ka radiation hoʻopuehu ʻia e 90%.ʻO ka mānoanoa o ka vermiculite he 65mm, ʻo ia ka mea like me 1mm papa alakaʻi.
No ka mahi kanu
No ka mea ʻo ka vermiculite pauka ka wai maikaʻi o ka lawe ʻana i ka wai, ka ea permeability, adsorption, looseness, non hardening a me nā waiwai ʻē aʻe, a he sterile a ʻaʻohe mea ʻawaʻawa ma hope o ka hoʻomoʻa ʻana i ka wela kiʻekiʻe, kahi kūpono i ke aʻa a me ka ulu ʻana o nā mea kanu.Hiki ke hoʻohana ʻia no ke kanu ʻana, ka hoʻoulu ʻana a me ka ʻoki ʻana i nā pua makamae a me nā kumulāʻau, nā mea kanu, nā kumu huaʻai a me nā hua waina, a me ka hana ʻana i nā mea kanu pua a me ka lepo momona.
ʻO ka hana ʻana no ka uhi kemika
ʻO ka vermiculite me ka pale ʻana i ka ʻakika, ʻo 5% a i ʻole ka liʻiliʻi o ka sulfuric acid, hydrochloric acid, acetic acid, 5% aqueous ammonia, sodium carbonate, hopena anti-corrosive.Ma muli o kona kaumaha māmā, looseness, smoothness, nui anawaena-a-mānoanoa ratio, ikaika adhesion, a me ke kiʻekiʻe wela kū'ē, hiki ke hoʻohana 'ia i mea hoʻopiha i ka hanaʻana o nā pena (pena ahi, anti-irritant pena, wai pena. ) no ka pale ʻana i ka pena ʻana a me ka hoʻouna ʻana i ka hana huahana.
No nā mea piliki
Loaʻa ka vermiculite i hoʻonui ʻia i ka lau a me nā waiwai insulation wela, hiki ke hoʻohana ʻia no nā mea friction a me nā mea braking, a he hana maikaʻi loa, ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole, a he mea hoʻonaninani hou no ka hoʻohaumia ʻana i ke kaiapuni.
