Iyo yakazara yekudzikisa ruzha coefficient yechinhu chitsva chealuminium foam inosvika 0.75, uye iyo inopfenyura coefficient mukati-kati-frequency renji ye250 ~ 1000Hz inosvika kupfuura 0.9, ichipfuura zvinonyanya kushandiswa-inobata zvinonzwika senge rock wool, gypsum board. , perforated metal plate, etc. Its comprehensive sound insulation and noise kuderedza kugona ndeye polyurethane foam. I7-10 nguva yepurasitiki, girazi faibha uye huchi aruminiyamu, uye ruzha rwayo rwekuvharisa rwuri padyo ne30dB kana ichishandiswa muzvitima zvinomhanya zvakanyanya nemabhokisi emotokari. Iyo itsva aluminiyamu furo zvinhu inoshandiswa muminda yakawanda uye yakawanda yekunyura kwekurira uye kuderedza ruzha uye zvinhu zvine hukama, kunyanya mumigwagwa mikuru yezvipingamupinyi, mugwagwa mukuru wenzira kuderedza ruzha, pasi pemvura mugero kuderedza ruzha, tunnel mavhavha; kurira kutorwa kwemadziro ekutuhwina; nyowani foam aluminium zvinhu kugadzira zvivakwa zvinotora ruzha, senge masitudiyo ekurekodha, makamuri ekudhibhura, mahoro emakonsati, horo dzemisangano, nhandare, nezvimwe.
Zvinhu zvikuru zvinokanganisa kunyudzwa kweruzha uye kudzikisa ruzha rwezvinhu zvitsva zvefoam aluminium ndeaya anotevera:
1. Iyo itsva aluminium foam material iine porous material, uye kurira kwayo kutorwa kwekuita kunonyanya kuoneka kune yakakwira frequency ruzha, kureva kuti, iyo inopfenyura coefficient yakakura munzvimbo yakakwirira frequency. Nekudaro, iyo inzwi yekunyudza mhedzisiro yeyakaderera frequency ruzha haina kunyatsonaka, saka iyo inzwi rekutora coefficient munharaunda yakaderera frequency idiki;
2. Ukobvu hwebhodhi rinotora inzwi rakagadzirwa nemhando itsva yealuminium foam yakasiyana, uye mhepo inopinza inzwi yakasiyana. Nekuwedzera kwehupamhi, iyo yakanakisa frequency yekutorwa-inzwi inokura yakananga kune yakaderera-frequency absorption. Nekudaro, kana kuwanda kweruzha kwakakura kupfuura 500Hz, iyo inopfenyura coefficient yechinhu chitsva chealuminium furo haina chekuita nekukora;
3. Kana kuwanda kwechinhu chitsva chealuminium furo kuchiwedzera, iyo yakanakisa kunyudzwa kweruzha panguva ino inozokurawo kusvika kune yakaderera-frequency ruzha, uye saizi yepore uye nhamba yechinhu chitsva chealuminium furo zvakare zvine misiyano iri pachena mukutorwa kweruzha. kushanda kwepaneru inotorwa inzwi.
Kuzvitaura zviri nyore, sarudzo dzakasiyana dzezvitsva zvealuminium furo zvinhu, senge ukobvu, density, porosity, nezvimwewo, zvinozokonzera akasiyana manzwiro ekunyudza. Hazvina mhosva kuti zvinhu zvitsva zvealuminium foam zvinosarudzwa sei, zvinonyanya kushanda kuenderana nemamiriro avo.
