ʻOi aku ka kiʻekiʻe o ka Sound Absorption Coefficient ʻoi aku ka maikaʻi no nā acoustics i loko o kou lumi.

ʻOi aku ka paʻakikī o ka hoʻopaʻa leo ʻana i ka hopena kūpono no kāu pilikia. Inā mākou e nānā iā ia ma ke ʻano o nā mea ʻoi loa, e noʻonoʻo kākou i kahi pā paʻa i hoʻohālikelike ʻia me ka pā i haku ʻia me nā ʻāpana fiberglass māmā māmā wale nō (ʻaʻohe pale maloʻo). Inā ʻoe i loko o ke keʻena pili ma hope o ka pā paʻa, e lohe ana ʻoe i nā kamaʻilio ʻana o kou hoalauna ʻoi aku ka liʻiliʻi ma mua o ka pā fiberglass wale nō ma waena o ʻoe a me kou hoalauna. I kēia laʻana, ʻoi aku ka maikaʻi o ka mea hoʻopaʻa leo ʻoi aku ka ʻoi aku ma mua o ka insulation batt fiberglass wale nō. Inā ʻoe i loko o ka lumi e kamaʻilio ana, eia naʻe, e lohe ana ʻoe i ka liʻiliʻi o ka leo inā ʻo kou pā he fiberglass batt i hoʻohālikelike ʻia me ka pā paʻa. I kēia laʻana, ʻoi aku ka maikaʻi o ka hoʻopaʻa leo fiberglass batt ma mua o ka pā pōhaku.

Ma kahi o 20 - 40% ʻoi aku ka lahilahi o nā scrim maʻamau ma mua o nā huahana i ulana ʻia mai ka wili like a me ke ʻano like.
He nui nā kūlana ʻEulopa e koi ana i ka uhi ʻana o nā membrane i ka liʻiliʻi ma nā ʻaoʻao ʻelua o ka scrim. Kōkua ka laid scrim i ka hana ʻana i nā huahana ʻoi aku ka lahilahi me ka ʻole e ʻae i nā waiwai ʻenehana i hoʻemi ʻia. Hiki ke mālama ʻia ma mua o 20% o nā mea maka e like me PVC a i ʻole PO.
ʻO nā scrim wale nō ka mea e ʻae i ka hana ʻana i kahi membrane uhi ʻekolu ʻāpana ʻāpana lahilahi (1.2 mm) i hoʻohana pinepine ʻia ma Central Europe. ʻAʻole hiki ke hoʻohana ʻia nā lole no nā membrane uhi ʻoi aku ka lahilahi ma mua o 1.5 mm.
ʻAʻole ʻike ʻia ke ʻano o kahi scrim i waiho ʻia ma ka huahana hope ma mua o ke ʻano o nā mea i ulana ʻia. ʻO kēia ka hopena i kahi ʻili maʻalahi a ʻoi aku ka maikaʻi o ka huahana hope.
ʻO ka maʻalahi o ka ʻili o nā huahana hope loa i loaʻa nā scrim i hoʻopaʻa ʻia e hiki ai ke wili a hoʻopili i nā papa o nā huahana hope me ka maʻalahi a me ka lōʻihi me kekahi.
ʻO nā ʻili maʻemaʻe e pale aku i ka lepo no ka lōʻihi a me ka hoʻomau.
ʻO ka hoʻohana ʻana i ka glassfibre scrim reinforced nonwovens per-mits i ʻoi aku ka wikiwiki o ka mīkini no ka hana ʻana i nā pā hale bitu-men. No laila hiki ke pale ʻia nā waimaka o ka manawa a me ka hana ma ka hale kanu bitumen.
Hoʻomaikaʻi maikaʻi ʻia nā waiwai mechanical o nā pā hale bitumen e nā scrims.
ʻO nā mea e maʻalahi ka nahae, e like me ka pepa, ka pepa a i ʻole nā ​​kiʻiʻoniʻoni mai nā plastik like ʻole, e pale ʻia mai ka haehae maikaʻi ʻana ma o ka laminating ʻana i kēia me nā scrim i hoʻopaʻa ʻia.
ʻOiai hiki ke hoʻolako ʻia nā huahana i ulana ʻia, e hoʻopili mau ʻia kahi scrim i hoʻopaʻa ʻia. Ma muli o kēia ʻoiaʻiʻo ua loaʻa iā mākou ka ʻike nui e pili ana i ka mea hoʻopili i kūpono i nā noi like ʻole. ʻO ke koho ʻana i ka mea hoʻopili kūpono hiki ke hoʻonui i ka hoʻopaʻa ʻana o ka scrim i waiho ʻia me ka huahana hope loa.
ʻO ka ʻoiaʻiʻo o ka ʻaoʻao o luna a me lalo i ka ʻaoʻao hoʻokahi o nā wili weft e hōʻoiaʻiʻo ʻia e paʻa mau nā kaula ma lalo o ka ʻāʻī. No laila, e hoʻopili koke ʻia nā mana tensile ma ka ʻaoʻao warp. Ma muli o kēia hopena, hōʻike pinepine ʻia nā scrims i hoʻemi nui ʻia. Ke laminating i kahi scrim ma waena o ʻelua mau ʻāpana o ke kiʻiʻoniʻoni a i ʻole nā ​​​​mea ʻē aʻe, e pono ka liʻiliʻi a hoʻopili ʻia a hoʻomaikaʻi ʻia ka cohesion o ka laminate. kaʻina hoʻomaloʻo. Ke alakaʻi nei kēia i ka preshrinking o ka polyester a me nā wili thermoplastic ʻē aʻe e hoʻomaikaʻi nui ai i nā hoʻomaʻamaʻa hope i hana ʻia e ka mea kūʻai.
