Kafukufuku Wokhudza Kuchepetsa Phokoso la Ma Compressor Osinthasintha Ogwiritsa Ntchito Basalt Fiber-Felt Composite

I. Mbiri ndi Kufunika kwa Kafukufuku
Kuipitsidwa kwa phokoso m'malo ozungulira kwakhala vuto lalikulu lomwe likukhudza thanzi la anthu komanso moyo wabwino, ndipo zida zamafakitale (monga ma compressor osinthasintha) ndizo zomwe zimathandizira kwambiri. Zipangizo zakale zoyamwa phokoso (monga thonje la thonje) sizigwira ntchito bwino m'malo opezeka ma frequency ambiri ndipo zimakhudzidwa ndi zinthu zachilengedwe monga kutentha. Ulusi wa basalt, chinthu chosapangidwa ndi zinthu zachilengedwe chomwe chimagwira ntchito bwino kwambiri chokhala ndi machubu komanso mphamvu zabwino kwambiri zoyankhulira, chakhala njira ina yabwino kwambiri yogwiritsira ntchito poletsa phokoso.

II. Makhalidwe ndi Kupanga kwa Ulusi wa Basalt 
1. Ubwino wa Zinthu Zofunika
Ulusi wa basalt, umodzi mwa ulusi anayi ofunikira kwambiri ku China, umathandiza kuyamwa mawu mwa kusintha kugwedezeka kwa mpweya mkati mwa pores ake kukhala mphamvu yotentha. Kuchulukana kwake ndi kapangidwe kake kabwino zimapangitsa kuti ukhale wogwira mtima kwambiri kuposa ulusi wa thonje woyamwa phokoso la broadband.

2. Njira Yopangira
Ofufuza ochokera ku Qingdao University adapanga chida chopangira zinthu mwa kusakaniza ulusi wa basalt ndi ulusi wa thonje. Mwa kukonza ma ratios ndi magawo ogwiritsira ntchito, chida chopangira zinthucho chinapeza kusinthasintha kwakukulu komanso magwiridwe antchito a mawu. Kuyesera kunawonetsa kuchepetsa kwake phokoso kwambiri pama frequency apamwamba (85 Hz) poyerekeza ndi ma frequency otsika (45 Hz), ndikugwira ntchito bwino kwambiri m'malo otentha kwambiri.

III. Kusanthula Kapangidwe Koyesera ndi Kuchepetsa Phokoso
1. Mikhalidwe Yoyesera
Kuyesera kunayesa kuchuluka kwa phokoso pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito (kutentha, kuchuluka) kwa compressor yosinthasintha, yokhala ndi ma frequency band otsika (45 Hz), apakati (65 Hz), ndi apamwamba (85 Hz). Kuyerekeza magwiridwe antchito kunapangidwa pakati pa basalt fiber felt ndi thonje wamba.

2. Zotsatira Zofunika
Kupambana Kwambiri Kwambiri: The nsalu ya basalt yopangidwa ndi ulusiadapeza chiŵerengero cha kuyamwa kwa mawu cha 0.85–0.95 pama frequency apamwamba, kuyandikira magwiridwe antchito a phenolic Ulusi wa Galasi chomverera.
Kudalira Kutentha: Mphamvu yake yoletsa phokoso imakula kutentha kotsika, pomwe zipangizo zachikhalidwe zimawonongeka kutentha kwambiri.
Kugwira Ntchito Konse: Chopangidwa ndi basalt chinachepetsa phokoso ndi ~20% poyerekeza ndi thonje lomwe linamveka pafupipafupi, zomwe zinachepetsa bwino phokoso la broadband kuchokera ku kugwedezeka kwa compressor ndi mpweya.

IV. Kuyerekeza ndi Ukadaulo Wachikhalidwe Wochepetsa Phokoso
1. Magwiridwe antchito a zinthu
Ngakhale zipangizo zachikhalidwe (monga ubweya wagalasi) zimakhala ndi ma coefficients ambiri oyamwa (0.90–0.99), zimavutika ndi ukalamba komanso nkhawa zachilengedwe. Fayilo ya basalt imagwirizana ndi magwiridwe antchito ake a mawu pomwe imapereka kukana kutentha kwambiri komanso kukonda zachilengedwe.

2. Zochitika Zogwiritsira Ntchito
Mosiyana ndi njira zothetsera mavuto (monga zotchingira, zotsekera muffler), nsalu ya basalt fiber felt imatha kuzunguliridwa mwachindunji ndi ma compressor kapena kuyikidwa muzinthu zosamveka bwino, zomwe zimapangitsa kuti zikhale zosavuta kuzikonzanso. Mwachitsanzo, mu machitidwe a HVAC, imachepetsa kutumiza phokoso lotsika kudzera m'mapaipi amkuwa kupita m'malo amkati.

V. Ziyembekezo ndi Mavuto
1. Ntchito Zamakampani ndi Zapakhomo
Felt ya basalt fiber ndi yabwino kwambiri pa ma compressor a mafakitale, ma air conditioner, ndi zina zambiri. Pophatikizidwa ndi ma enclosures, imatha kuchepetsa phokoso la malire a fakitale kufika pansi pa 45 dB, kukwaniritsa miyezo ya chilengedwe.

2. Kukonza Zaukadaulo
Kukweza Ma Frequency Ochepa: Mapangidwe osakanikirana (monga mapangidwe a masangweji) angathandize kuti ma frequency asamagwire bwino ntchito.
Kuchepetsa Mtengo: Kukulitsa kupanga ndikofunikira kwambiri pochepetsa ndalama, chifukwa ulusi wa basalt umakhalabe wokwera mtengo.

VI. Mapeto
Ma composites a basalt-felt-felt, okhala ndi mapangidwe abwino komanso njira zopangira, akuwonetsa kuthekera kwakukulu kowongolera phokoso la ma frequency apamwamba mu ma compressor a ma frequency osiyanasiyana. Kafukufuku wamtsogolo ayenera kuyang'ana kwambiri kukhazikika pansi pa zovuta zogwirira ntchito komanso mgwirizano ndi ukadaulo wina wochepetsa phokoso kuti awonjezere kugwiritsidwa ntchito.
