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 hwepanhi rinotora inzwi rakagadzirwa nemafuta matsva ealuminium foam rakasiyana, uye mhepo inobata inzwi yakasiyana. Sezvo hukobvu huchiwedzera, iyo inobata-inzwi frequency inokura munzira yekutora yakaderera frequency. 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, ruzha rwekutorwa kweruzha panguva ino zvakare runowedzera kusvika kune yakaderera-frequency ruzha, uye saizi uye saizi yemapores eiyo nyowani yealuminium furo zvinhu zvakare zvine misiyano iri pachena mukunzwika. kutorwa kwekuita kwepaneru-inotora ruzha.
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.
