Acoustic panels rau phab ntsa: hom, yam ntxwv, xaiv

Niaj hnub no, txoj kev tsim ntawm ib qho chaw kawm zoo tshaj plaws yog tsis tuaj yeem ua rau rooj tog zaum thiab ua yeeb yam. Lub rov tshwm sim ntawm khw chaw zov me nyuam, chaw ua hauj lwm qauv ntawm qhib qhov chaw, kev kho mob tshiab, kev kawm ntawv ntau ceg thiab cinemas muaj txhab lub Scope ntawm suab-absorbing cov ntaub ntawv. Los tsim ib qho chaw zoo nyob rau hauv kev kho kom zoo ntawm thaj chaw ntau dua siv cov acoustic panels rau phab ntsa thiab ceilings. Lawv siv ua kom txo qis ntawm qhov kev xav, ua rau kev txawj ntse ntawm kev hais lus, thiab normalize lub siab.

Acoustic cov ntaub ntawv

Nyhuv ntawm acoustic panels yog tiav los ntawm kev siv lawv absorbing cov ntaub ntawv. Lawv tuaj yeem yog cov neeg muaj keeb kwm ntuj tsim thiab keeb kwm. Feeb ntau, qhov kho kom zoo nkauj ntawm cov chav siv khoom raws li ntoo, textiles los yog gypsum. Tam sim no, acoustic panels rau phab ntsa yog tsim los ntawm gypsum, ntoo, pob zeb hauv av ntaub plaub, fiberglass, polyurethane ua npuas thiab melomin.

Hom phab ntsa acoustic panels

Nyob ntawm cov ntaub ntawv siv, lub suab-ci ntsa iab rau phab ntsa tau muab faib ua hom nram qab no:

• Ntoo fiber, cellulose. Nyob rau hauv ib lub cement los yog gypsum phau ntawv, cov paib ntawm qhov ntau thiab tsawg, ntau ntawm 600 mm, thiab thicknesses txog li 25 hli yog tsim. Xws li cov iav tau pleev xim rau hauv cov xim twg.
• Basalt paj rwb ntaub plaub. Phiaj basalt wool muaj siab suab haum thiab hluav taws. Muaj peev xwm muaj moth-eye, structural or smooth surface.
• Ntoo Phom Ntoo. Sheet perforated khoom yog characterized los ntawm kev tsis txaus siab. Muaj peev xwm ua tau txawv txawv txawv. Cov khoom yog yooj yim dyed.
• Gypsum. Embossed daim hlau ntawm cov ntaub ntawv no, thiaj li hu ua 3D panels, muaj kev nyab xeeb ntawm thaj tsam thiab tsis muaj hluav taws xob. Muaj nyob rau hauv ntau hom ntawv, tuab thiab cov qauv. Cov khoom siv yog ntsia nruab nrab ntawm "ntub" cov tshuab, tsis siv lub thav duab thiab cov txheej txheem. Yuav pleev xim rau xim.
• Fiberglass. Hauv kev tsim cov khoom siv acoustic panels, cov khoom siv ntom ntom nrog lub fiberglass txheej los yog pleev xim rau. Vuas seem yog mounted rau ntawm phab ntsa uas siv cov khoom tshwj xeeb. Qhov loj ntawm cov ntawv yog txiav txim los ntawm cov khw, piv txwv li, acoustic panels rau phab ntsa ntawm "Ekofon" muaj qhov loj ntawm 2700 x 1200 hli, ib tug tuab ntawm 40 mm.
• Polyurethane ua npuas ncauj. Daim hlau los ntawm cov khoom siv no ua tau yooj yim nrog cov nplaum ncaj qha rau ntawm cov phab ntsa. Lub thickness ntawm cov khoom siv yog los ntawm 20 mus rau 100 mm nrog qhov ntev ntawm 1000 x 1000 hli. Tus qauv xim yog graphite nrog txawv txawv qauv.
• Melamine. Sound absorbing panels rau cov phab ntsa uas ua los ntawm cov khoom siv hluavtaws yog tsim nyob rau hauv ib tug loj uas yog ib tug ntau ntawm 600 mm, nrog ib tug tuab ntawm 20 mus rau 100 mm. Lub hauv paus xim ntawm cov khoom yog lub teeb grey, xim muaj pub rau hauv cov xim.

Ntsiab Ntaus

• Sound absorption coefficient. Cwj pwm muaj peev xwm ntawm lub vaj huam sib luag kom nqes suab tsis. Tus nqi yuav muaj tus nqi ntawm 0 mus 1. Xoom sib sau mus rau tag nrho lub suab ntawm lub suab, 1 - mus rau tag nrho nqus. Rau unit unit tau txais kev qhib lub qhov rai ntawm 1 square. M
• Coefficient ntawm lub teeb pom kev zoo. Tshaj tawm hauv feem pua, 0% sib haum rau tag nrho nqhuab lub teeb, 100% sib ntsib rau tag nrho cov kev xav. Qhov nruab nrab, cov kab lus cuam tshuam yeej muaj lub teeb pom kev zoo ntawm 60-80%. Nws yog qhov tseem ceeb tshaj plaws kom coj tus cwj pwm no mus rau hauv tus account rau cov qab nthab.
• Hws noo tuaj yeem. Cov nqi no qhia tau hais tias cov khoom ua rau cov dej. Muab hais tias cov ntaub ntawv acoustic muaj ib tus qauv ntxeem tau, lawv yog cov raug cov dej no. Tshwj xeeb tshaj yog qhov kev ntsuas no tseem ceeb heev rau cov qab nthab.
• Thermal conductivity. Cwj pwm lub peev xwm ntawm cov khoom siv los ua kom sov. Vim nws txoj kev ntxeem tau, pob ntsa acoustic yog lub ntsuas kub zoo nyob rau hauv no.

Qab nthab Acoustic Panels

Nyob rau hauv niaj hnub interiors, lub qab nthab nrog lub suab nrov-absorbing yog ntsib ntau zaus. Acoustic ceilings, raws li txoj cai, yog kev txhawb rau ntawm lub wireframe (piv txwv li, daim hlau "Armstrong"), uas tso cai rau koj mus nkaum tom lawv cov kev sib txuas lus. Cov kab xev tuaj yeem ua tau ntawm hom qhib los yog nraim. Qab nthab panels ntxiv rau qhov yuav tsum tau ua kom muaj kev xav kom txo tau cov khoom ntawm cov qauv uas txhawb nqa. Yog li ntawd, rau cov khoom ntawm cov khoom qab nthab acoustic, cov ntaub ntawv fibrous ntuj lossis cov iav fibers siv. Cov duab qhov ntev ntawm cov ntsiab lus no feem ntau yog ua hauv ntau ntawm 600 hli, piv txwv li cov dav hlau Armstrong, tab sis tuaj yeem ncav cuag txog li ntawm 2400 hli. Lub thickness ntawm lub panels yog los ntawm 12 mus rau 40 hli. Cov nplais ntawm cov phab ntsa acoustic slabs yuav ua tau los yog ua los yog ntxhib. Cov phiaj xwm yuav tau pleev xim, tab sis feem ntau yog muab dawb.

Qhov feem ntau nyob rau hauv lub dai kom zoo nkauj ntawm chav yog acoustic paib "Armstrong", hom "Baikal". Cov lus qhia hauv qab no yog muab rau hauv qab no:

• Kev nqus suab - 0,45.
• Hws noo yog 90%.
• Teeb reflection yog 85%.
• Cov thermal conductivity yog 0.052 W / (m × deg).
• Qhov ntev qhov ntev yog 600 x 600 x 12 hli.
• Cov hluav taws kub-kev ntxawg - G1, V1, D1, T1.

Xaiv cov ntaub ntawv Acoustic

Qhov kev txiav txim siab parameter ntawm kev xaiv yog suab absorption. Nws tus nqi yog txiav txim tau los ntawm acoustic xam, thiab yog hais tias nws yog qhov nyuaj ua nws, ces xaiv cov khoom nrog lub siab tshaj plaws suab nqus tus nqi. Xaiv cov acoustic panels rau phab ntsa, tshwj xeeb tshaj yog sab nraum zoov, nws yog ib qhov tsim nyog los siv cov khoom siv nrog thermal conductivity. Qhov no yuav txo tau cov nqi cua sov.

Rau qab nthab panels nws yog ib qho tseem ceeb them sai sai mus rau lub teeb thiaj: lub siab nws yog, lub zog lub chav tsev, thiab yog tsawg tshaj li tus nqi ntawm hluav taws xob teeb pom kev zoo. Tsis tas li ntawd rau saum qab nthab vuas ntau yam pauv loj dej kuj, nws tsis tshua muaj nqi yuav ua tau kom sagging.

Cov hluav taws kub

Vim tias cov khoom siv hluav taws xob siv rau hauv thaj chaw lossis pej xeem cov chaw, xws li hauv cov chav nrog loj heev nyob ntawm tib neeg, nws tseem ceeb heev rau kev suav cov khoom hluav taws kub ntawm cov ntaub ntawv. Cov tseem ceeb yog:

• Flammability.
• Alienability.
• Kev haus luam yeeb ua kom muaj peev xwm.
• Toxicity.
