Galasi Lokhala ndi Ukadaulo Woyamwa Mazwi Pochepetsa Phokoso
Phokoso lakhala limodzi mwa "zonyansa zosaoneka" zomwe timakumana nazo m'moyo wamakono. Phokoso la magalimoto pamsewu waukulu, sitima zodutsa, ntchito zomanga, ndi chisokonezo cha malo amalonda zonse zimatha kulowa m'malo amkati ndikusokoneza chitonthozo. Kunyumba, phokoso limatha kuchepetsa kupuma ndi kukhazikika. Muofesi, limawonjezera kupsinjika ndikuchepetsa zokolola. Pachifukwa ichi, zatsopano mu zipangizo zomangira zikukhala zofunika kwambiri, kuphatikizapo kupanga magalasi okhala ndi ukadaulo wokoka mawu ndi kuchepetsa phokoso womwe umapangidwira kuthandiza kuchepetsa phokoso popanda kuwononga kuwala kwachilengedwe ndi kukongola.
N’chifukwa Chiyani Galasi Ndi Lofooka Pakulamulira Mafoni?
M'nyumba zamakono, magalasi amagwiritsidwa ntchito kwambiri: mawindo akuluakulu, makoma a pakhoma, makoma a maofesi, komanso zitseko zagalasi. Komabe, galasi lokhazikika ndi "lolimba" komanso lopyapyala poyerekeza ndi makoma a njerwa kapena konkire, zomwe zimapangitsa kuti mafunde a phokoso alowe mosavuta. Phokoso lakunja lingalowe m'chipinda kudzera mu kugwedezeka kwa galasi, mipata mu chimango, ndi malo olumikizirana omasuka. Zotsatira zake, ngakhale makoma ali okhuthala ndipo madenga ndi osamveka, galasi nthawi zambiri limakhala njira yayikulu yolowera mawu.
Apa ndi pomwe ukadaulo wa magalasi olankhulidwa umathandizira: osati kungopangitsa galasi kukhala "lokulirapo," komanso kupanga kapangidwe kake ndi zigawo zake kuti achepetse kutumiza mawu pamene akuchepetsa mphamvu ya mawu.
Mfundo Zoyambira: Kuthetsa Kugwedezeka ndi Kusamalira Kumveka
Phokoso ndi mafunde opanikizika omwe amayenda mumlengalenga. Mafunde a phokoso akagunda galasi, mphamvu ina ya phokoso imaonekera, ina imayamwa, koma yotsalayo imagwedezeka mu galasi ndipo imatumizidwa m'chipindamo. Kuchepetsa phokoso kumachitika kudzera mu njira zingapo zofunika:
1. Onjezani kulemera: chinthucho chikalemera komanso chokhuthala, chimakhala chovuta kugwedezeka.
2. Pangani dongosolo lokhala ndi zigawo: zigawo ziwiri za galasi zokhala ndi malo opumira pakati pawo zimapangitsa kuti pakhale kukana kwina.
3. Kugwiritsa ntchito gawo lonyowa: gawo la polima limatha kuyamwa mphamvu ya kugwedezeka kotero kuti kumveka bwino kuchepe.
4. Kukonza mipata ndi mafelemu: magwiridwe antchito a galasi amakhudzidwa kwambiri ndi ubwino wa kuyika ndi kulimba kwa chimangocho.
Ukadaulo woyamwa/kuchepetsa phokoso mu galasi nthawi zambiri umaphatikiza njira zoposa imodzi mwa zomwe zili pamwambapa.
Mitundu ya Ukadaulo wa Galasi Wochepetsera Phokoso
1. Galasi Lopaka Ma Acoustic
Mtundu uwu ndi umodzi mwa njira zodziwika kwambiri m'nyumba za m'mizinda. Galasi lopaka utoto limakhala ndi mapepala awiri (kapena kuposerapo) agalasi omangiriridwa pamodzi ndi filimu pakati. Mu galasi lopaka utoto, filimuyi si filimu wamba, koma ndi filimu yolumikizana ndi mawu (monga acoustic PVB kapena polymer yapadera) yomwe ili ndi mphamvu yayikulu yochepetsera kugwedezeka.
Pamene mafunde a phokoso apangitsa galasi kugwedezeka, cholumikiziracho chimayamwa mphamvu zina za kugwedezeka, kuchepetsa kuchuluka kwa phokoso lomwe limatuluka. Ubwino wina wa galasi lopangidwa ndi laminated ndi chitetezo chake: ngati litasweka, zidutswa za galasi zimatsalira pa cholumikiziracho ndipo sizimabalalika.
2. Chipinda cha Magalasi Chophimba Kawiri kapena Choteteza (IGU)
Kuphimba kawiri kumagwiritsa ntchito magalasi awiri olekanitsidwa ndi chipinda cholumikizira ndi chipinda cha mpweya (kapena mpweya wopanda mpweya). Malo amenewa amakakamiza mawu kudutsa mu "media" ndi ma interfaces angapo, zomwe zimachepetsa kutumiza kwa mawu. Komabe, ndikofunikira kudziwa kuti mphamvu ya mawu ya kuvala kawiri imadalira kwambiri:
– makulidwe a galasi lililonse,
- m'lifupi mwa mpweya,
- mtundu wa mpweya wodzaza,
- ndi ubwino wa chosindikizira.
Kuti zinthu ziyende bwino, opanga nthawi zambiri amaphatikiza magalasi awiri ndi magalasi opangidwa ndi laminated mbali imodzi, zomwe zimapangitsa kuti zinthu zikhale bwino kwambiri.
3. Kupaka utoto kosafanana
Galasi yokhala ndi makulidwe ofanana mbali zonse ziwiri nthawi zina imakhala ndi vuto la kumva kugwedezeka kwa ma frequency ena. Mwa kusintha makulidwe a galasi (mwachitsanzo, 6 mm mbali imodzi ndi 8 mm mbali inayo), kugwedezeka kwa ma frequency kumatha "kusweka," motero kuchepetsa phokoso, makamaka pamitundu yosiyanasiyana ya mawu monga kuchuluka kwa magalimoto.
4. Galasi yokhala ndi Microstructured Coating kapena Metamaterial Technology (Innovation Direction)
Mu kafukufuku wa zinthu, njira zogwiritsira ntchito ma micro-peforations kapena metamaterial structures kuti zisinthe mafunde a mawu zabuka. Lingaliroli likufanana ndi ma acoustic panels okhala ndi mabowo ang'onoang'ono omwe "amakola" mphamvu ya mawu pafupipafupi inayake. Ngakhale kuti kugwiritsidwa ntchito kwake kwakukulu sikudziwika bwino monga magalasi opangidwa ndi laminated kapena mawindo opangidwa ndi magalasi awiri, njira yaukadaulo iyi ikulonjeza njira zina zenizeni zamitundu ina ya phokoso.
Kodi Ukadaulo Umenewu Ukufunika Kwambiri Kuti?
Magalasi onyamula mawu amagwiritsidwa ntchito kwambiri m'malo ndi m'nyumba zomwe zimakhala ndi phokoso lalikulu, mwachitsanzo:
- nyumba zomwe zili pafupi ndi misewu ikuluikulu, njanji, kapena ma eyapoti,
- nyumba zogona pakati pa mzinda,
- mahotela ndi zipatala zomwe zimafuna malo abata,
- studio ya nyimbo, chipinda chochitira misonkhano, ndi chipinda chophunzirira,
- maofesi otseguka omwe amafuna magalasi olekanitsa koma amasungabe chinsinsi.
Chochititsa chidwi n'chakuti, magalasi olankhulirana akufunidwa kwambiri pa zosowa zapakhomo, chifukwa kalembedwe ka nyumba zamakono komwe kamagwiritsa ntchito mipata yambiri ikuluikulu kamakonda kuwonjezera kukhudzidwa ndi mawu ochokera kunja.
Kuyimba kwa Acoustic: Kodi Muyenera Kuyang'ana Chiyani?
Mu dziko la ma acoustics omanga, chizindikiro chimodzi chomwe chimagwiritsidwa ntchito kwambiri ndi kuthekera kwa chinthu chomanga kuchepetsa phokoso, nthawi zambiri chimafotokozedwa mu ma decibel (dB) pogwiritsa ntchito magawo monga Sound Transmission Class (STC) kapena Rw (m'miyezo ina yapadziko lonse). Manambala apamwamba nthawi zambiri amasonyeza kuti mawu amatetezedwa bwino.
Komabe, ndikofunikira kumvetsetsa kuti magwiridwe antchito a galasi mu labotale amatha kusiyana ndi momwe zinthu zilili m'munda. Izi nthawi zambiri zimachitika chifukwa cha zinthu zotsatirazi:
- mipata yomwe ili mu chimango cha zenera yomwe si yolimba,
- ma gaskets opanda khalidwe labwino,
- kukhazikitsa kosalondola,
- kukhalapo kwa njira zotulutsira mawu kudzera m'makoma, mpweya wopuma, kapena nyumba (kutumiza kwa flanking).
Izi zikutanthauza kuti ngakhale galasi labwino kwambiri silingakhale labwino ngati mawindo sakuteteza phokoso ndipo kapangidwe kake sikoyenera.
Kuphatikiza ndi Kapangidwe Koyenera ka Nyumba
Magalasi oletsa kuyamwa/kuchepetsa phokoso adzakhala othandiza kwambiri ngati atathandizidwa ndi kapangidwe kake, mwachitsanzo:
- sankhani mafelemu abwino a mawindo (monga ndi makina otsekera ambiri),
- onetsetsani kuti malo oyikamo ndi osavuta komanso kuti mipata ikhale yochepa,
- gwiritsani ntchito makatani okhuthala kapena makatani omveka ngati chowonjezera,
- kuwonjezera zinthu za m'malo monga mitengo kapena mipanda yolimba kuti muchepetse phokoso lisanafike m'nyumbamo,
- ganizirani malo omwe pali mipata komanso momwe nyumbayo ikuyendera poyang'ana komwe phokoso likuchokera.
Mwa kuyankhula kwina, galasi la acoustic si yankho limodzi, koma ndi gawo la njira yopangira chitonthozo cha acoustic.
Ubwino Wina Woposa Kuchepetsa Phokoso
Chochititsa chidwi n'chakuti, makina ena a magalasi a acoustic amaperekanso maubwino ena:
- kugwiritsa ntchito mphamvu moyenera: kuphimba kawiri kumatha kuchepetsa kusamutsa kutentha,
- kuchepetsa kuwala kwa dzuwa likaphatikizidwa ndi zophimba zina,
– chitetezo (makamaka galasi lopangidwa ndi laminated),
- chitonthozo cha maganizo chifukwa cha malo opanda phokoso.
Kwa eni nyumba ambiri, ubwino wophatikizana uwu umapangitsa kuti kuyika ndalama mu galasi la acoustic kumveke ngati "kothandiza" kuposa njira zotetezera phokoso pang'ono.
Mavuto ndi Zoganizira za Mtengo
Ukadaulo wa magalasi onyamula mawu nthawi zambiri umakhala wokwera mtengo kuposa galasi wamba, makamaka ngati umagwiritsa ntchito magalasi opangidwa ndi laminated acoustic ndi mayunitsi apamwamba okhala ndi magalasi awiri. Kuwonjezera pa ndalama zogulira zinthu, kuyika bwino kumawonjezeranso ndalama zogwirira ntchito. Komabe, ngati ndalamazo zagwiritsidwa ntchito kwa nthawi yayitali—makamaka m'malo aphokoso—galasi lopangidwa ndi lacoustic lingathandize kwambiri moyo wabwino, mtengo wa nyumba, komanso magwiridwe antchito a chipinda.
Kusankha kwa zinthu zomwe ziyenera kusinthidwa kuti zigwirizane ndi kuchuluka kwa phokoso lozungulira. Pamalo aphokoso kwambiri, kugwiritsa ntchito zinthu monga magalasi awiri ophimbidwa ndi galasi lopangidwa ndi acoustic laminated + mafelemu osamveka nthawi zambiri kumakhala kothandiza kwambiri kuposa kungowonjezera makulidwe a galasi limodzi.
Mapeto
Galasi yokhala ndi ukadaulo woyamwa mawu ndi kufinya ndi chinthu chofunikira kwambiri pa zomangamanga zamakono, makamaka m'malo okhala ndi phokoso komanso odzaza kwambiri m'mizinda. Kudzera m'njira monga magalasi opangidwa ndi laminated, mawindo awiri opangidwa ndi magalasi (IGUs), mapangidwe osafanana, ndi kafukufuku wa zinthu zakuthupi, magalasi salinso malo ofooka pakulamulira phokoso. Komabe, kuti mupeze zotsatira zabwino kwambiri, kusankha magalasi kuyenera kutsagana ndi kuyika koyenera, kuletsa phokoso la chimango, ndi njira yonse yopangira nyumba.
Pogwiritsa ntchito bwino, magalasi opangidwa ndi acoustic amatithandiza kusangalala ndi kuwala kwamakono komanso zithunzi popanda "mtengo" wa phokoso. Pakati pa kufunikira kwakukulu kwa malo abwino komanso athanzi, ukadaulo uwu si chinthu chongowonjezerapo, koma ndi gawo lofunikira kwambiri pa moyo wabwino m'nthawi ya mizinda.
