Ma ka ʻōlelo ʻana i ka pale kani, pono nā mea a pau e kamaʻāina iā ia.Ma ke ʻano he kiaʻi alanui, kūkulu ʻia ma ke kumu walaʻau a i ʻole ma nā ʻaoʻao ʻelua o ke alanui.Ke hoʻouna ʻia ka walaʻau i ka pale leo, e hoʻopaʻa ʻia a e komo i kahi ʻāpana.A laila hoʻokumu nui ʻia ka pale leo ma ke ʻano o ke kani ʻana.He aha?I kēia lā, e haʻi aku nā mea hana pale kani iā ʻoe e pili ana.
Mea hana pale kani
1. Huluhulu aniani
ʻO ka huluhulu aniani Centrifugal kahi ʻano mea hoʻoheheʻe wela i puka mai i ka makahiki 1980.He lālā ia o ka ʻohana fiber aniani.Hoʻohana ia i ka ʻenehana puhi centrifugal kiʻekiʻe o ka honua e fibrillate i ke aniani i hoʻoheheʻe ʻia a pīpī ʻia me ka resin thermosetting.A laila ho'ōla wela ka mea.
Hana ʻia ka hulu hipa aniani i ke one quartz, feldspar, sodium silicate, boric acid, a me nā mea ʻē aʻe, i hana ʻia me ka pulupulu pulu aniani hoʻoheheʻe kiʻekiʻe.
ʻO nā hiʻohiʻona huahana o ke aniani kani-absorbing pulupulu: māmā kaumaha, kiʻekiʻe kani absorption coefficient, maikaʻi flame retardant hana a me ka maikaʻi loa kemika paʻa, a he moisture-hōʻoia.
2. Aluminum fiber
ʻO ka papa hoʻoheheʻe leo alumini he mea hoʻoheheʻe leo ʻano metala i hana ʻia e kahi ʻupena alumini ʻaoʻao ʻelua ʻaoʻao sandwiching i ka manaʻo alumini a me ka alumini alumini.Loaʻa iā ia ka hana hoʻoheheʻe kani maikaʻi, ka ikaika tensile kiʻekiʻe, nā mea māmā, ka halihali kūpono a me ke kūpaʻa maikaʻi o ka wā.
Loaʻa nā hiʻohiʻona o ka fiber alumini:
ʻO ka mānoanoa o ka alumini fiber sound absorbing panel ma waena o 0.8-2mm, a he 1.4-3.2kg/m2 ka mānoanoa o ka papa.Maʻalahi ka lawe ʻana ma muli o kona liʻiliʻi a me ke kaumaha māmā
1. ʻO ka 35mm mānoanoa hoʻemi haʻahaʻa haʻahaʻa he 0.7, a me ka 1.8mm mānoanoa hoʻemi hoʻohaʻahaʻa leo he 0.9.
Mea hoʻonani: Hiki ke pena ʻia ka papa i nā kala like ʻole, nani loa ke kala, me ka hopena hoʻonaninani a me ke kani ʻana.
Ka hana maʻalahi: Hiki ke hana maikaʻi ʻia ka pā alumini, maʻalahi e wili, kūlou a ʻokiʻoki.Ke hoʻokō ʻia ke kūkulu ʻana, ʻaʻohe lepo fiber e hoʻopuehu a hoʻohaumia i ke kaiapuni a pili i ke olakino o nā limahana.
2, pahu alumini
Hana ʻia ka pahu alumini me ka alumini maʻemaʻe a i ʻole i hoʻohui ʻia me nā mea hoʻohui i ka alumini alumini.He huʻa a loaʻa nā ʻano metala a me ka huʻa.
He maikaʻi loa ka hana hoʻoheheʻe leo o ka pā alumini foam, ʻaʻole ʻoi aku ka nui o ke kani ʻana o ka leo ma mua o 0.64, a ʻo ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa ma waena o NRCO.75, he mea maikaʻi loa ia no ka walaʻau kaʻa e pili ana i ka waena a me ke alapine haʻahaʻa. , a ʻoi aku ka maikaʻi ma mua o nā ʻano mea kani kani.Hiki ke hoʻomaʻemaʻe ponoʻī ka ʻili o ka alumini foamed ma hope o ka ua, me ka ʻole o ka pili ʻana i ka hana acoustic.
