Phokoso lathunthu lochepetsera phokoso la zinthu zatsopano za aluminiyamu za thovu limafika pa 0.75, ndipo mphamvu yoyamwitsa yapakati pa 250 ~ 1000Hz imafika kupitilira 0.9, kupitilira zida zomwe zimagwiritsidwa ntchito nthawi zambiri zotulutsa mawu monga ubweya wa miyala, gypsum board. , perforated zitsulo mbale, etc. ake mabuku kutchinjiriza phokoso ndi phokoso kuchepetsa mphamvu ndi polyurethane thovu. Ndi nthawi 7-10 kuposa pulasitiki, ulusi wagalasi ndi aluminiyamu ya uchi, ndipo kutsekemera kwake kumakhala pafupi ndi 30dB kumagwiritsidwa ntchito m'masitima othamanga kwambiri ndi mapanelo a bokosi lamagalimoto. Chithovu chatsopano cha aluminiyamu chimagwiritsidwa ntchito m'magawo ochulukirachulukira chifukwa cha mayamwidwe ake apamwamba kwambiri komanso kuchepetsa phokoso ndi zinthu zina zofananira, makamaka m'misewu yayikulu yotchinga, kuchepetsa phokoso la misewu yayikulu, kuchepetsa phokoso la sitima zapamadzi, zolowera mumsewu; phokoso mayamwidwe a dziwe osambira khoma; zida zatsopano za aluminiyamu zopangira zingwe zomangirira mawu, monga ma situdiyo ojambulira, zipinda zojambulira, malo ochitirako konsati, mabwalo amisonkhano, mabwalo amasewera, ndi zina zambiri.
Zinthu zazikulu zomwe zimakhudza kuyamwa kwa mawu komanso kuchepetsa phokoso la zida zatsopano za aluminiyamu ndi izi:
1. Chithovu chatsopano cha aluminiyamu ndi chinthu cha porous, ndipo kutsekemera kwake kumamveka bwino kwambiri kwa phokoso lapamwamba kwambiri, ndiko kuti, kutsekemera kwa phokoso kumakhala kwakukulu m'dera lapamwamba. Komabe, kuyamwa kwamphamvu kwamawu otsika pafupipafupi sikoyenera kwambiri, kotero kuti kutulutsa mawu kumadera otsika pafupipafupi kumakhala kochepa;
2. Makulidwe a bolodi lotulutsa mawu lopangidwa ndi aluminiyamu yatsopano ya thovu ndi yosiyana, ndipo ma frequency omvera amasiyana. Ndi kuchuluka kwa makulidwe, ma frequency abwino kwambiri amayamwa mawu amakula mpaka kumayamwa otsika kwambiri. Komabe, kumveka kwa phokoso kukakhala kokulirapo kuposa 500Hz, mphamvu yoyamwitsa yamtundu watsopano wa aluminiyamu ya thovu ilibe chochita ndi makulidwe;
3. Pamene kachulukidwe ka zinthu zatsopano za aluminiyamu chithovu chikuwonjezeka, kumveka bwino kwa mayamwidwe a phokoso panthawiyi kudzakhalanso ndi phokoso laling'ono, ndipo kukula kwa pore ndi chiwerengero cha zinthu zatsopano za aluminiyumu zimakhalanso ndi kusiyana koonekeratu pamayamwidwe a phokoso. magwiridwe antchito a gulu lotengera mawu.
Kunena mwachidule, zosankha zosiyanasiyana za zida zatsopano za aluminiyamu, monga makulidwe, kachulukidwe, porosity, ndi zina zotere, zimabweretsa mayamwidwe osiyanasiyana amawu. Ziribe kanthu momwe zida zatsopano za aluminiyamu zimasankhidwa, ndizothandiza kwambiri kuti zigwirizane ndi zomwe zikuchitika.
