Pamene anthu akuganizira kwambiri za malo okhala m'nyumba, zipangizo zoyamwa mawu, monga njira yofunika kwambiri yowongolera malo okhala m'nyumba, zakhala zikugwiritsidwa ntchito kwambiri m'nyumba zosiyanasiyana, m'magalimoto, ndi m'makina. Ndiye, kodi mfundo yoyamwa mawu ya zipangizo zoyamwa mawu ndi iti?
Mfundo yotengera mawu ya zida zotulutsa mawu imatha kukhala yamitundu iwiri: mtundu wa impedance ya mpweya ndi mtundu wa pore impedance. Mfundo ziwirizi zidzafotokozedwa mwatsatanetsatane pansipa.
Choyamba, mpweya impedance mtundu absorbent zakuthupi
Air impedance zida zotulutsa mawu zimagwiritsa ntchito kuwunikira ndi kufalitsa mafunde amawu ndi gasi wosanjikiza pamwamba pa zinthuzo kuti akwaniritse kuyamwa kwamawu. Makamaka, mafunde akamagunda pamwamba pa chinthu chomwe chimatulutsa mawu, amalumikizana ndi mpweya womwe uli pamwamba pa chinthucho. Ndiko kuti, gawo la phokoso la phokoso likuwonekera, ndipo gawo lina la phokoso la phokoso limadutsa pamtunda wa mpweya ndikulowa mkati mwa zinthu zomwe zimamveka phokoso, ndiyeno mosalekeza zimawonetsera, zimachepetsetsa, ndikubalalitsa mkati mwa zinthuzo, ndipo potsirizira pake zimasandulika kukhala mphamvu ya kutentha ndikuyamwa.
Pochita izi, kutsekeka kwa gasi wosanjikiza ndi chinthu chofunikira kwambiri pozindikira kuwonetsera ndi kufalitsa mafunde amawu. Kusiyanitsa kwakukulu pakati pa kusanjikiza kwa gasi wosanjikiza ndi kutsekeka kwa mpweya, kumapangitsa kuti mafunde amawu azitha kudutsa pamwamba pa zinthuzo, potero amapeza kuyamwa kwabwinoko. Chifukwa chake, zida zotulutsa mpweya zotulutsa mpweya nthawi zambiri zimagwiritsa ntchito njira zina zapadera zochizira pamwamba pa zinthuzo, monga kuwonjezera zida zaporous, kuchepetsa kuuma kwapamtunda, kukulitsa kuuma kwapamtunda, ndi zina zambiri, kuonjezera kusanjikiza kwa gasi, potero kumapangitsa kuti mawuwo amve bwino.
Chachiwiri, zida za pore impedance zotengera mawu
Pore impedance yamtundu wa zinthu zotulutsa mawu ndikugwiritsa ntchito kapangidwe ka pore mkati mwazinthu zomwe zimawunikiridwa pamawu, kubalalitsa ndi kuyamwa kuti mumve bwino. Mfundo yaikulu ya pore impedance zipangizo zomangira phokoso ndikuti mafunde a phokoso mkati mwa zinthuzo amalumikizana ndi mamolekyu a mpweya mkati mwa zinthu, zomwe zimapangitsa kusintha kwamphamvu ndi kuyenda, motero kumatulutsa kuwonetsera, kubalalikana ndi kuyamwa.
Mosiyana ndi zipangizo zogwiritsira ntchito mpweya, phokoso la phokoso la pore-impedance-absorbent-sound-absorbent likugwirizana ndi mapangidwe a pore azinthu. Makamaka, pamene pore m'mimba mwake ndi yaikulu kuposa phokoso wavelength, phokoso phokoso akhoza kulowa pore, resonance ndi mayamwidwe; ndipo pamene pore awiri ndi ang'onoang'ono kuposa phokoso wavelength, phokoso funde sangathe kulowa mkati mwa pore, koma pore mozungulira kusinkhasinkha ndi kubalalika.
Chifukwa chake, zipangizo zoyamwa mawu za pore impedance nthawi zambiri zimagwiritsa ntchito kapangidwe kapadera ka pore kuti zikwaniritse zotsatira zabwino kwambiri zoyamwa mawu . Mwachitsanzo, zipangizo zina zoyamwa mawu za pore-impedance zimapangidwa ndi zipangizo za ulusi wambiri, ndipo kapangidwe ka pore ka ulusi uliwonse ndi kosiyana, kuti zikwaniritse kuyamwa kwa mafunde a mawu a ma frequency osiyanasiyana. Zipangizo zina zoyamwa mawu za pore-impedance zimapangidwa ndi thovu kapena uchi, zomwe zimagwiritsa ntchito ma pores ndi mipata ya kukula kosiyana kuti zikwaniritse zotsatira zoyamwa mawu.
Tikumbukenso kuti phokoso-absorbsorbent zotsatira mpweya-impedance ndi pore-impedance phokoso absorbent zipangizo zimakhudzidwa ndi zinthu zingapo, monga makulidwe a zinthu, kachulukidwe, porosity, pamwamba mankhwala njira ndi zina zotero. Chifukwa chake, popanga ndikusankha zida zoyamwitsa mawu, m'pofunika kuganizira zochitika zenizeni ndi zofunikira, ndikusankha zida zoyenera zomvera mawu.
Chidule
Mfundo yotengera mawu ya zida zotulutsa mawu imatha kufotokozedwa mwachidule m'mitundu iwiri: mtundu wa air-impedance ndi pore-impedance. Kutulutsa mawu kwamtundu wa Air impedance ndiko kugwiritsa ntchito wosanjikiza wa gasi pamwamba pa zinthuzo kuwonetsa ndikutumiza mafunde amawu kuti azindikire kuyamwa kwamawu, pomwe pore impedance yamtundu wa pore imagwiritsa ntchito mawonekedwe amkati azinthu kuti awonetse, kubalalitsa ndi kuyamwa mafunde amawu kuti azindikire kuyamwa kwamawu. Pogwiritsa ntchito, m'pofunika kusankha zinthu zomveka bwino zomwe zimamveka bwino molingana ndi momwe zimagwiritsidwira ntchito ndi zofunikira, ndipo panthawi imodzimodziyo, samalani ndi zotsatira za makulidwe a zinthu, kachulukidwe, porosity, chithandizo chapamwamba ndi zinthu zina zomwe zimakhudzidwa ndi mawu.
