Suab-absorbing panels yog zoo kawg nkaus haum rau lub qab nthab installation thiab yog ib qho ntawm feem ntau cov kev daws teeb meem nyob rau hauv tam sim no architectural acoustic engineering.
Technical Feasibility: Muaj ntau hom khoom siv hauv suab-absorbing panels txiav txim seb lawv tsim nyog rau lub qab nthab installation. Cov khoom lag luam tseem ceeb hauv kev ua lag luam suav nrog polyester fiberboard, ntxhia wool board, perforated wood board, thiab fiberglass board, tag nrho cov uas txhawb joist installation systems. Siv polyester fiberboard ua piv txwv, nws qhov ceev yog feem ntau ntawm 0.2-0.4 g / cm³, thiab nws lub zog khoov tuaj yeem ncav cuag tshaj 15 MPa, muaj peev xwm tiv taus qhov hnyav ntawm lub qab nthab thiab me me vibrations. Mineral wool board, vim nws cov ntxhia fiber ntau cov ntsiab lus, ua tiav qhov ntsuas hluav taws kub ntawm Chav A (GB8624-2012), ua rau nws tsim nyog rau cov chaw uas muaj kev nyab xeeb hluav taws kub. Thaum lub sij hawm installation, yuav tsum tau them nyiaj mloog mus rau lub joist spacing. Rau cov pa joists, qhov sib nrug ntawm 400-600 mm raug pom zoo, thaum lub teeb steel joists, qhov no tuaj yeem so mus rau 600-800 hli kom ntseeg tau tias cov panels ruaj khov.
Application Scenario Expansion: Daim ntawv thov ntawm qab nthab suab-absorbing vaj huam sib luag tau nthuav dav dhau qhov xwm txheej hauv chav sib tham mus rau ntau yam xws li kev kawm, kev kho mob, thiab kev lom zem. Piv txwv li, tom qab txhim kho lub suab- nqus cov qab nthab hauv cov chav kawm hauv tsev kawm ntawv, Speech Intelligibility Index (STI) tuaj yeem txhim kho ntau dua 0.2, txhim kho kev kawm tau zoo. Hauv tsev kho mob CT scan cov chav, kev teeb tsa cov suab sib xyaw ua ke-absorbing panels tuaj yeem ua tau raws li kev tiv thaiv hluav taws xob thaum txo cov cuab yeej ua haujlwm suab nrov qis dua 35dB. KTV chav feem ntau siv perforated ntoo suab-absorbing vaj huam sib luag, ua ke nrog tsawg-frequency trapping designs, kom ua tiav tag nrho - zaus tswj suab nrov. Nws yog ib nqi sau cia hais tias nyob rau hauv ib puag ncig ntub, noo noo{12}} cov ntaub ntawv resistant yuav tsum tau xaiv, xws li cov ntxhia wool boards nrog ib tug melamine txheej, uas nws cov dej nqus tus nqi yuav tswj tau qis dua 5%.
Cov Txheej Txheem Txhim Kho Cov Ntsiab Lus Tseem Ceeb: Kev tsim kho qab nthab yuav tsum ua raws li lub hauv paus tseem ceeb ntawm "kev nyab xeeb ntawm cov qauv - acoustic kev ua tau zoo - cov nyhuv zoo nkauj." Ua ntej, cov txheej txheem load-cov kabmob muaj peev xwm yuav tsum raug txheeb xyuas; ib qho - taw tes dai quab yuam yuav tsum tsis pub tsawg tshaj 50kg (JGJ16-2008). Qhov thib ob, lub suab-absorbing cheeb tsam yuav tsum tau xam raws li nyob rau hauv lub chav tsev ntim, nrog ib tug kev pab them nqi ntawm 30% -50% feem ntau pom zoo. Thaum kawg, kev sib koom tes zoo nkauj yuav tsum tau txiav txim siab; Piv txwv li, thaum sib koom ua ke nrog lub teeb pom kev zoo, lub vaj huam sib luag 200-300mm yuav tsum tau tshwj tseg. Cov txheej txheem tsim kho suav nrog: ntsuas thiab teeb tsa → teeb tsa lub ntsiab keel → kho cov keel thib ob → txiav cov panels → sealing kho. Cov pob qij txha ntawm cov panels yuav tsum tau ntim nrog elastic sealant kom tsis txhob muaj suab nrov bridging. Rau qhov tsis xwm yeem zoo li lub qab nthab, tus qauv tsim qauv tuaj yeem siv tau. Qhov loj ntawm ib lub vaj huam sib luag yog pom zoo kom tswj tsis pub dhau 600 × 1200mm rau kev thauj mus los yooj yim thiab kev teeb tsa.
