Bincike akan Rage Hayaniyar Na'urori masu Sauyawa-Mai-Tsarki Amfani da Basalt Fiber-Felt Composite
I. Bayanan Bincike da Muhimmanci
Gurbacewar hayaniyar mahalli ya zama wani muhimmin al'amari da ke shafar lafiyar ɗan adam da ingancin rayuwa, tare da kayan aikin masana'antu (misali, masu matsa lamba masu canzawa) kasancewa babban mai ba da gudummawa. Abubuwan sha na al'ada na amo (misali, fiber auduga ji) suna nuna iyakacin aiki a cikin babban mitoci kuma suna da saurin kamuwa da abubuwan muhalli kamar zazzabi. Basalt fiber, wani babban aiki inorganic abu tare da porous tsari da kuma m acoustic Properties, ya fito a matsayin manufa madadin ga amo sarrafa aikace-aikace.
II. Halaye da Kerawa na Basalt Fiber
1. Abubuwan Amfani
Basalt fiber, daya daga cikin manyan filaye masu inganci guda hudu na kasar Sin, yana inganta shayar da sauti ta hanyar canza girgizar iska a cikin pores zuwa makamashin zafi. Ingantattun yawa da tsarin sa sun sa ya fi tasiri fiye da zaren auduga don shayar da amo.
2. Tsarin Kerawa
Masu bincike daga Jami'ar Qingdao sun ɓullo da wani nau'in ji ta hanyar haɗa filayen basalt da zaren auduga. Ta hanyar inganta ma'auni da sigogin sarrafawa, haɗin gwiwar ya sami babban sassauci da aikin ƙararrawa. Gwaje-gwaje sun nuna mafi girman raguwar amo a manyan mitoci (85 Hz) idan aka kwatanta da ƙananan mitoci (45 Hz), tare da ingantaccen inganci a cikin ƙananan yanayin zafi.
III. Ƙirƙirar Gwaji da Binciken Rage Surutu
1. Yanayin Gwaji
Gwaje-gwaje sun ƙididdige matakan amo a ƙarƙashin yanayin aiki daban-daban (zazzabi, mitar) na madaidaicin matsa lamba, mai rufe ƙasa (45 Hz), tsakiyar (65 Hz), da manyan (85 Hz) mitoci. An yi kwatancen kwatance tsakanin jigon basalt fiber da ji na auduga na al'ada.
2. Mabuɗin Sakamako
Maɗaukaki Mai Girma: The basalt fiberya sami daidaitaccen ɗaukar sauti na 0.85-0.95 a manyan mitoci, yana kusa da aikin phenolic. Gilashin Fiber ji.
Dogaro da Zazzabi: Ƙarfinsa na hana amo ya inganta a ƙananan yanayin zafi, yayin da kayan gargajiya sun lalace ƙarƙashin yanayin zafi.
Aiki Gabaɗaya: Haɗin basalt ya inganta raguwar amo ta ~ 20% idan aka kwatanta da auduga da aka ji a mitar guda ɗaya, yadda ya kamata yana rage hayaniyar faɗaɗa daga girgizar kwampreso da kwararar iska.
IV. Kwatanta da Fasahar Rage Hayaniyar Gargajiya
1. Kayan Aiki
Duk da yake kayan al'ada (misali, ulun gilashi) suna nuna ƙimar haɓaka mai girma (0.90-0.99), suna fama da matsalolin tsufa da muhalli. Basalt fiber ji yayi daidai da aikin su na sauti yayin da yake ba da ingantaccen juriya da yanayin yanayi.
2. Yanayin aikace-aikace
Ba kamar hanyoyin da ba za a iya amfani da su ba (misali, shinge, mufflers), filaye na basalt ana iya nannade shi kai tsaye a kusa da compressors ko haɗa su cikin sigar hana sauti, sauƙaƙe sake fasalin. Misali, a cikin tsarin HVAC, yana rage saurin watsa amo ta bututun tagulla zuwa sararin cikin gida.
V. Halaye da kalubale
1. Masana'antu da Aikace-aikacen Gida
Basalt fiber ji yana ɗaukar alƙawarin don kwampreshin masana'antu, raka'a na kwandishan, da ƙari. Haɗe tare da shinge, zai iya rage hayaniyar iyakar masana'anta zuwa ƙasa da 45 dB, saduwa da ƙa'idodin muhalli.
2. Inganta Fasaha
Haɓaka Ƙarƙashin Mitar: Ƙirar ƙira (misali, tsarin sanwici) na iya haɓaka ƙarancin mitoci.
Rage farashi: Haɓaka samarwa yana da mahimmanci don rage farashi, saboda fiber na basalt ya kasance mai tsada.
VI. Kammalawa
Basalt fiber-fet composites, tare da ingantattun sifofi da hanyoyin ƙirƙira, suna nuna mahimmancin yuwuwar sarrafa amo mai girma a cikin masu matsa lamba masu canzawa. Ya kamata bincike na gaba ya mayar da hankali kan kwanciyar hankali a ƙarƙashin hadaddun yanayin aiki da haɗin kai tare da sauran fasahohin rage amo don faɗaɗa aiki.
