Aiki Gabaɗaya: Haɗin basalt ya inganta rage hayaniya da ~20% idan aka kwatanta da ji na auduga a daidai wannan mitar, yana rage hayaniyar broadband daga girgizar matsewa da iskar iska.
IV. Kwatantawa da Fasahar Rage Hayaniya ta Gargajiya
1. Aikin Kayan Aiki
Duk da cewa kayan gargajiya (misali, ulu na gilashi) suna da yawan shan ruwa (0.90–0.99), suna fama da tsufa da matsalolin muhalli. Jikin basalt fiber ya dace da aikin sautinsu yayin da yake ba da juriya ga zafi da kuma kyawun muhalli.
2. Yanayin Aikace-aikace
Ba kamar mafita marasa aiki ba (misali, wuraren rufewa, masu toshe iska), za a iya naɗe zaren fiber na basalt kai tsaye a kusa da na'urorin damfara ko kuma a haɗa su cikin tsarin hana sauti, wanda ke sauƙaƙa sake haɗa su. Misali, a cikin tsarin HVAC, yana rage yawan hayaniyar da ke yawo ta bututun tagulla zuwa cikin sararin cikin gida.
V. Abubuwan Da Za Su Faru Da Kuma Kalubale
1. Aikace-aikacen Masana'antu da Gidaje
Jikin zare na basalt yana da alhaki ga na'urorin compressor na masana'antu, na'urorin sanyaya daki, da sauransu. Idan aka haɗa shi da wuraren rufewa, yana iya rage hayaniyar iyaka ta masana'anta zuwa ƙasa da 45 dB, wanda ya cika ƙa'idodin muhalli.
2. Inganta Fasaha
