Hoʻokaʻawale ʻia nā huahana huluhulu aniani no nā paia sandwich i ʻelua ʻano: ka huluhulu aniani a me ka papa huluhulu aniani.Hiki ke uhi ʻia ka ʻili o ka ʻili a i ʻole ka papa me ka ʻeleʻele ʻeleʻele a i ʻole e hoʻopili ʻia me kahi papa ʻeleʻele (kumu: China Insulation Network) i manaʻo ʻia no ka hoʻoikaika ʻana.He kūpono no ka hoʻohana pāʻoihana., Ka wela wela o na paia papalua ma na hale hana a me na hale aupuni.

Hiki i nā huahana hulu hipa aniani no nā paia sandwich ke hāʻawi iā ʻoe i kēia mau pōmaikaʻi: Kāohi i ka condensation, hoʻemi i ke kaumaha o ka pā, hoʻonui i ka wahi hoʻohana, mālama i ka ikehu, hoʻonui i ka hōʻoluʻolu, ka hoʻoheheʻe leo, a me ka pale ʻana i ke ahi.

ʻO ka huluhulu aniani Centrifugal he maikaʻi ke kani absorption no ke kani waena a kiʻekiʻe.ʻO nā kumu nui e pili ana i ka hoʻokō kani ʻana o ka huluhulu aniani centrifugal ʻo ka mānoanoa, ka nui a me ke kū ʻana o ka ea.ʻO ka Density ke kaumaha o ka mea ma ka mika cubic.ʻO ke kūpaʻa kahe o ka ea ka ratio o ke kaomi ea a me ka wikiwiki o ka ea ma nā ʻaoʻao ʻelua o ka mea ma kēlā me kēia mānoanoa.ʻO ke kū ʻana o ka ea ka mea nui loa e pili ana i ka hoʻokō kani ʻana o ka huluhulu aniani centrifugal.Inā he liʻiliʻi loa ke kahe o ke kahe ʻana, ʻo ia hoʻi he mea liʻiliʻi ka mea a ua maʻalahi ka haʻalulu o ka ea, a ua hoʻemi ʻia ka hana hoʻokō kani;inā ʻoi aku ka nui o ke kūpaʻa kahe, ʻo ia hoʻi, paʻakikī ka mea, paʻakikī ka haʻalulu o ka ea, a hoʻemi ʻia ka hana hoʻoheheʻe kani.

No ka hulu hipa aniani centrifugal, ʻoi aku ka maikaʻi o ka hoʻokō ʻana i ke kani.Ma ka ʻenekinia maoli, paʻakikī ke ana ʻana i ke kūpaʻa kahe o ka ea, akā hiki ke hoʻohālikelike ʻia a hoʻomalu ʻia e ka mānoanoa a me ka nui.

1. Me ka hoʻonui ʻana o ka mānoanoa, piʻi nui ka coefficient absorption leo o ke alapine a me ke alapine haʻahaʻa, akā hoʻololi liʻiliʻi ke alapine kiʻekiʻe (ʻoi aku ka nui o ka absorption kiʻekiʻe).
2. Ke hoʻololi ʻole ka mānoanoa, piʻi ka nui o ka nui, a piʻi pū ka coefficient absorption leo o ke alapine waena haʻahaʻa;akā, i ka piʻi ʻana o ka puʻupuʻu puʻupuʻu i kekahi pae, lilo ka mea i mea paʻakikī, ʻoi aku ka nui o ke kahe ʻana ma mua o ke kūpaʻa kahe maikaʻi loa, a e emi iho ka coefficient absorption leo.No ka hulu hipa aniani centrifugal me ka mānoanoa nui o 16Kg/m3 a me ka mānoanoa o ʻoi aku ma mua o 5cm, ʻo ka haʻahaʻa haʻahaʻa 125Hz ma kahi o 0.2, a ʻo ke alapine a me ke alapine kiʻekiʻe (> 500Hz) kokoke i ka 1.
3. Ke hoʻomau nei ka mānoanoa o ka mānoanoa mai 5cm, piʻi mālie ka helu haʻahaʻa haʻahaʻa haʻahaʻa.Ke oi aku ka mānoanoa ma mua o 1m, e pili pū ana ka helu haʻahaʻa haʻahaʻa haʻahaʻa 125Hz i ka 1. I ka wā e mau ai ka mānoanoa a piʻi ka nui o ka puʻupuʻu, e hoʻomau ka piʻi ʻana o ka haʻahaʻa haʻahaʻa o ka huluhulu aniani centrifugal.Ke kokoke ka nui o ka nui i ka 110kg/m3, hiki i ka hana hoʻoheheʻe leo i kona waiwai kiʻekiʻe, kahi kokoke i 0.6-0.7 ma kahi mānoanoa o 50mm a me ke alapine o 125Hz.Ke ʻoi aku ka nui o ka nui ma mua o 120kg/m3, e emi ana ka hana hoʻoheheʻe ʻana i ke kani no ka mea e paʻa ana ka mea, a ʻoi loa ka hopena o ka hana hoʻoheheʻe leo waena a me ke kiʻekiʻe.Ke ʻoi aku ka nui o ka nui ma mua o 300kg/m3, hoʻemi nui ka hana hoʻoheheʻe kani.

ʻO ka mānoanoa o ke kani-absorbing aniani hulu hipa maʻamau i hoʻohana ʻia i ka acoustics architectural he 2.5cm, 5cm, 10cm, a ʻo kona mānoanoa nui he 16, 24, 32, 48, 80, 96, 112kg/m3.Hoʻohana maʻamau 5cm mānoanoa, 12-48kg/m3 centrifugal aniani hulu hipa.
