Aluminium Foam Yakakwirira-Kushanda Acoustic Panels Tunnel Inzwi Inofa uye Kuderedza Ruzha
Product Description:
Yakavharwa-sero foam aluminium mapaneru anogadzirwa kuita yakakwirira-inoshanda-inobata mapaneru mushure mekuvhiyiwa kweperforation (Φ2mm maburi, perforation rate ye1-3%), ane yakanakisa kuita-kunanzva kunoita ruzha, uye mwero wekutora ruzha unogona kusvika 60% kusvika 90%. Sezvo pamusoro pechinyorwa ichi chisina ndege, ine yakanakisa nzvimbo inotaridza kutaridzika kwekurira kwekuita basa, uye panguva imwecheteyo, ine mutsindo wekunyudza basa re perforated Helmholtz resonance acoustic absorber, iyo inova nechokwadi chekukwirira kwekunzwa kwekurira. Uye zvakare, munzvimbo ine hunyoro, yakajairwa acoustic zvinhu inotora mvura uye inowedzera, iyo inzwi yekunyudza coefficient inodzikiswa zvakanyanya, nepo aluminium furo zvinhu isingatore mvura, kurira kwayo kunyura hakudzike.
Aluminium foam plate kuseri kweseti yehukobvu hwakasiyana hwedenga remhepo, iyo huru frequency yekutorwa kwekurira kwakasiyana, nehupamhi hwedenga remhepo kubva pa0mm kusvika 90mm, iyo huru frequency yekutorwa kwezwi kubva pa2000Hz zvichidzika kusvika 300Hz kana zvakadaro. Kana ukobvu hwemhepo yemhepo iri 10, 30, 60, 90mm, iyo huru frequency yeyakanyanya kunyura ruzha ndeye 1000Hz, 500Hz, 400Hz, 300Hz kana zvakadaro. Zvinoenderana neruzha frequency kugovera dhizaini foam rate acoustic pani kuseri kwemhepo layer gobvu. Mugwagwa mukuru, pasi perwizi, tunzira dzepasi pegungwa uye dzimwe mota dzakagadzira ruzha rukuru runosvika 400Hz, rwekudzika-ruzha, saka zvipingamupinyi zvemugwagwa mukuru, pasi perwizi uye pasi pegungwa tunnel-inonyudza madziro ealuminium foam acoustic mapaneru kuseri kwekugadzika. iyo 60mm gobvu yemhepo layer, ruzha rwekudzikisa ruzha rwakanaka. Ruzha rweRailroad rwuri pakati nepakati uye rwakakwira frequency ruzha pamusoro pe1000Hz, 20mm gobvu remhepo rakaiswa kuseri kwealuminium foam inopfeza-inobata ndiro ine yakanaka yekudzikisa ruzha.
