Yuav ua li cas kom tau txais qhov zoo tshaj plaws suab rwb thaiv tsev rau niaj hnub sab hauv xim xim - dawb Ntoo Qhov Rooj?

1. Qhov Rooj Nplooj Thickness: Thawj "Qhov Zoo Tshaj Plaws" rau lub suab rwb thaiv tsev

Seb koj tab tom nrhiav ibsoundproof ntoo qhov roojrau koj lub tsev, ibacousticntoo qhov roojrau lub tsev kawm ntawv chav kawm, los yog asoundproof tsev so qhov rooj, lub thickness ntawm lub qhov rooj yog ib qho ntawm cov tseem ceeb yam cuam tshuam rau nws lub suab rwb thaiv tsev kev ua tau zoo.

Raws li "ACOUSTIC MASS LAW", qhov ntom ntom ntom ntom (kg / m²) ntawm nplooj ntawv lub qhov rooj ncaj qha txiav txim siab nws cov huab cua - xa suab rwb thaiv tsev (Rw). Rau xim - dawb lub qhov rooj ntoo, thickness yog qhov ncaj qha lub cev tsis muaj zog. Cov ntaub ntawv soj ntsuam dav dav qhia pom (hauv tib lub qhov rooj tiav thiab cov khoom ntim khoom):

• 40mm Thickness: Qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom Rw tsuas yog 30 ~ 33dB. Cov qib no tsuas tuaj yeem thaiv kev sib tham txhua hnub (kwv yees li 60dB), nrog rau kev ua haujlwm tsis zoo tiv thaiv kev nrov nrov lossis qis - suab TV zaus, haum rau chav cia lossis chav nres tsheb.
• 45mm Thickness: Rw nce mus rau 35 ~ 38dB. Ua tau zoo txo ​​qhov nruab nrab - mus rau - lub suab nrov nrov, ua tau raws li qhov xav tau ntawm kev ceev ntiag tug ntawm cov chav pw zoo tib yam, uas tuaj yeem siv rau ib qhochav tsev lub qhov rooj, tab sis tseem nyuaj rau tiv nrog cov suab nrov hauv pem teb lossis lub suab nrov ntawm cov khoom siv loj.

  

   

• 50 ~ 55mm Thickness: Rw mus txog 40 ~ 43dB. Ntawm qhov tuab no, lub qhov rooj nplooj tuaj yeem txo cov suab nrov sab nraum zoov, thiab nrog kev sib khi zoo, nws tuaj yeem tsim "qib tsev qiv ntawv-" qib" qhov chaw nyob ntsiag to, qhov kev teeb tsa tseem ceeb rau siab - kawg cov xim ntsiag to- lub qhov rooj dawb, uas yog qhov zoo rau lub hnub qub - cov chav tsev qhua thiab cov tsev qiv ntawv loj.
• Rau cov thicknesses ntawm 60mm thiab saum toj no: Rw tuaj yeem tshaj 45dB, mus txog lub teb chaws suab rwb thaiv tsev txheej txheem qib 6 (GB/T 8485-2008). Txawm li cas los xij, cov thickness nce ntxiv rau pob khawm, xav tau cov pob khawm ntxiv, thiab qhov chaw xav tau siab heev ntawm qhov verticality ntawm lub qhov rooj thiab phab ntsa. Yog li ntawd, nws yog feem ntau siv nyob rau hauv tshwj xeeb scenarios xws li kaw studios los yog tsev ua yeeb yam.

Vim muaj qhov sib txawv ntawm cov tub ntxhais filling ntom ntom, lub suab rwb thaiv tsev ntawm cov xim xim - cov qhov rooj dawb tuaj yeem hloov pauv los ntawm ± 2dB ntawm tib lub thickness, tab sis cov ntaub ntawv saum toj no tuaj yeem siv los ua tus qauv xaiv. Rau txhua txhua 5 hli nce nyob rau hauv thickness, tsawg- zaus suab rwb thaiv tsev zoo los ntawm kwv yees li 2-3dB, tab sis cov txiaj ntsim marginal txo qis tom qab 60 hli, xav tau cov khoom optimization.

 

2.The Acoustic Game of Filling Materials:

Khoom Wood Mechanical Soundproofing Board vs. Aluminium Honeycomb Ntawv. Cov core filling cov ntaub ntawv yog cov tub ntxhais uas txiav txim siab suab rwb thaiv tsev efficiency. Tam sim no, kev ua lag luam rau xim - qhov rooj dawb feem ntau siv ob txoj hauv kev:

2-1. Khoom Wood Mechanical Soundproofing Board

Los ntawm CNC milling, ob npaug -X sib tshuam kab pheeb ces kaum kev txhawb nqa network yog tsim, rhuav tshem cov kev ntxhov siab sab hauv ntawm cov ntoo thiab txhim kho txoj kab ntsug elastic coefficient thiab tsis kam deformation. Sab hauv ntxeem tau / ntau- kab noj hniav qauv, ua ke nrog lub suab yoj thaiv cov ntsiab lus, thiab qee cov khoom ntim nrog lub suab- nqus cov ntaub ntawv xws li quartz wool hauv grooves;

Nws qhov zoo ntawm acoustic nyob rau hauv: ntau- kab noj hniav qauv zoo thaiv lub suab nthwv dej propagation txoj kev, ua rau muaj kev cuam tshuam thiab dissipating suab zog;

Cov yam ntxwv damping: Ntoo fibers lawv tus kheej muaj anelasticity, uas tuaj yeem hloov kev vibrational mechanical zog rau hauv lub zog sab hauv (lub zog hluav taws xob), tshwj xeeb tshaj yog absorbing 500 ~ 2000Hz tib neeg lub suab ntau zaus.

Cov kev ntsuam xyuas pom tau tias cov xim 46 hli - lub qhov rooj acoustic dawb uas siv qhov ntim no tuaj yeem ua tiav Rw ntawm 37dB, nrog cov khoom zoo sib xws thiab tsis kam mus rau deformation, ua rau nws tus nqi ntau tshaj - cov khoom siv suab nrov zoo.

2-2. AluminiumHoneycombCore Qhov Rooj Qauv

Cov qauv no siv cov honeycomb-zoo li txheej txheej ua los ntawm txhuas ntawv ci lossis ntawv, nrog cov laug cam txuas rau saum thiab hauv qab. Thaum qhov no yog qhov tseeb heev lub teeb thiab ruaj khov, nws muaj ntau yam teeb meem nrog lub suab rwb thaiv tsev:

Ua ntej, suab "siv lub shortcut." Honeycomb lub lattice phab ntsa yog rigidly txuas; suab tsis qaug zog thaum nws tsoo lawv, tab sis es tsis txhob mus ncaj qha los ntawm cov phab ntsa nyuaj, zoo li footsteps ntawm ib qho nyuaj pem teb mus deb.

Qhov thib ob, lub hlwb honeycomb "hu nkauj." Cov huab cua hauv txhua lub xov tooj ntawm tes ua haujlwm zoo li cov kab noj me me, thiab thaum nws ntsib qee zaus ntawm lub suab, lawv resonate (xws li tshuab cua rau hauv lub raj mis), ua rau nruab nrab - lub suab nrov nrov tau pom ntau dua thiab tawm tau yooj yim dua.

Feem ntau, rau 45mm thickness, aluminium honeycomb core xim xim -dawb qhov rooj muaj acoustic tsis kam (Rw) tsuas yog li 32-34dB thiab zoo li tsis muaj tsawg- zaus cais. Txawm li cas los xij, nws qhov zoo muaj xws li lub teeb yuag thiab hluav taws kub tsis kam, ua rau nws tsim nyog rau cov chaw ua haujlwm qhov chaw uas lub suab rwb thaiv tsev yuav tsum tsis siab. Rau qhov zoo tshaj plaws suab rwb thaiv tsev, khoom ntoo acoustic panels yuav tsum tau ua ntej. Yog hais tias lub teeb yuag thiab tus nqi tsim nyog tau txiav txim siab, daim ntawv honeycomb tuaj yeem siv tau, tab sis lub thickness yuav tsum tau nce mus rau tsawg kawg yog 55 hli los them rau nws qhov tsis zoo acoustic.

3. Ntau-theem Kev Tiv Thaiv Sealing Strips: Los ntawm Ib Leeg - txheej mus rau tag nrho

Qhov rooj qhov khoob yog "qhov tsis txaus ntseeg" hauv lub suab rwb thaiv tsev-txawm tias muaj lub qhov rooj vaj huam sib luag Rw ntawm 40dB, qhov sib txawv ntawm 1mm tuaj yeem txo cov suab nrov tag nrho los ntawm 10-15dB. Tus qauv ntawm lub sealing sawb txiav txim siab cov huab cua nruj:

• Ib leeg sealing sawb (ib leeg EPDM lossis silicone sawb): ntsia ntawm ib sab ntawm lub qhov rooj, nws tsuas yog compressed ntawm ib qho taw tes thaum lub qhov rooj kaw. Nws qhov compression stroke yog txwv, thiab ntev - siv lub sij hawm tuaj yeem ua tau yooj yim ua rau deformation mus tas li, ua rau qhov khoob nyuaj kho. Kev sim cov ntaub ntawv qhia tau hais tias tag nrho cov suab rwb thaiv tsev ntawm lub qhov rooj nyob rau hauv ib lub foob yog txo los ntawm 5-8dB piv rau lub qhov rooj liab qab vaj huam sib luag, thiab nws tsuas yog haum rau ib puag ncig uas tsis tshua muaj suab nrov tsis rhiab heev.
• Ob tus nplaig-thiab- zawj sealing sawb (stepped ob lub foob): Lub npoo ntawm lub qhov rooj nplooj yog ua tiav rau hauv ob kauj ruam, nrog rau ib txoj hlua khi ntawm txhua kauj ruam, ua ob txoj hlua khi. Lub suab nthwv dej yuav tsum ua ntej dhau los ntawm thawj txheej ntawm kev xav thiab attenuation, thiab tom qab ntawd nkag mus rau txheej thib ob los ntawm cov kab noj hniav tortuous, uas yog sib npaug rau kev nthuav dav txoj kev ntev. Qhov kev tsim no tuaj yeem txhim kho lub suab rwb thaiv tsev tag nrho ntawm lub qhov rooj los ntawm 3-4 dB thiab muaj kev kam rau siab dua rau kev teeb tsa tsis raug, ua rau nws ua tus qauv hauv nruab nrab - mus rau - siab- kawg cov qhov rooj tsis muaj xim.
• Muab ob npaug rau- taug qab, ntim tag nrho EPDM sealing sawb: Qhov no yog tam sim no qhov kev sib khi zoo tshaj plaws. Lub qhov rooj thiab lub qhov rooj nplooj txhua tus muaj kev ywj pheej khiav nrog EPDM ua npuas ncauj strips. Thaum lub qhov rooj kaw, ob lub strips cuam tshuam los ua ib qho kev sib txuas mus tas li, ib puag ncig. Nyob rau tib lub sijhawm, EPDM cov khoom siv tiv thaiv kev laus thiab muaj qhov compression rebound tus nqi ntau dua lossis sib npaug li 95%. Ua ke nrog lub hollow ua npuas ncauj raj qauv, nws tuaj yeem hloov mus rau qhov tsis sib xws me me hauv phab ntsa. Thib peb- kev sim tog qhia tau hais tias siv qhov kev sib khi no rau ntawm tib lub qhov rooj vaj huam sib luag txhim kho lub suab rwb thaiv tsev tag nrho los ntawm 6-9 dB piv rau ib qho kev sib khi ib leeg, yuav luag tshem tawm qhov sib txawv ntawm qhov cuam tshuam, uas yog qhov tseem ceeb lav rau kev ua tiav Rw Ntau dua lossis sib npaug rau 40.

4. Qhov Zoo Tshaj Plaws ntawm Cov Pem Teb Sweeping Sawb:

Qhov sib txawv nruab nrab ntawm lub hauv qab ntawm lub qhov rooj nplooj thiab hauv av (feem ntau yog 5-10 hli) yog ib qho "shortcut" rau suab tsis dhau. Ordinary ruaj plua plav cheb strips tsuas yog tiv thaiv plua plav thiab tsis muaj kev cuam tshuam rau lub suab rwb thaiv tsev. Lub tshuab nqa tsis siv neeg nqa cheb sealing sawb siv cov tshuab compression lossis sib nqus ua rau thaum lub qhov rooj kaw ua rau lub hauv qab sawb nqis los vertically thiab nias nruj nreem rau hauv av (los yog qhov chaw pib), ua tiav lub foob airtight.

 

Cov cuab yeej no tuaj yeem pab txhawb 3-5 dB ntawm lub suab rwb thaiv tsev ntawm nws tus kheej, nrog rau kev cuam tshuam tshwj xeeb hauv 125-500 Hz qis zaus ntau, vim cov suab tsis tshua muaj suab muaj qhov ntev wavelengths thiab yooj yim cuam tshuam los ntawm qhov sib txawv hauv qab.

 

Ua ke nrog cov lus hais saum toj no ob- taug qab tag nrho- cov ntaub ntawv sib khi, lub qhov rooj tag nrho lub suab rwb thaiv tsev tuaj yeem txhim kho ntxiv. Piv txwv li, 45 hli tuab xim - qhov rooj dawb (cov khoom siv tseem ceeb: cov khoom ntoo) muaj Rw ntawm kwv yees li 36 dB yam tsis muaj lub foob cheb; Tom qab kev teeb tsa, kev ntsuas qhov tseeb qhia tau hais tias Rw ntawm 39-40 dB, nce mus txog qhov cuam tshuam ntawm 50mm tuab qhov rooj.

5. Qhov cuam tshuam ntawm Qhov Rooj Ntawm Qhov Ncauj Qhov Ncauj ntawm Lub Suab Rwb Thaiv Tsev:

5-1. Kev sib piv ntawm MelamineVeneerthiab PVCVeneer:

Melamine Paper + HDF (Kub-Nias Txoj Kev):

Raumelamine tiav qhov rooj, melamine- daim ntawv impregnated yog fused nrog HDF substrate nyob rau hauv qhov kub siab (170 ~ 200 degree) thiab siab siab (5 ~ 8MPa). Cov resin nkag mus rau hauv fiber ntau pores ntawm HDF nto (2 ~ 3mm), ua ib txheej nruj thiab ntom ntom ntom ntom ntom ntom tom qab kho. Qhov sib npaug sib npaug ntawm thaj chaw no tuaj yeem ncav cuag 1.1 ~ 1.3 g / cm³, siab dua li ntawm HDF core (feem ntau yog 0.8 ~ 0.9 g / cm³), sib npaug rau ntxiv txheej ntxiv ntawm "thin armor" rau lub qhov rooj ntawm daim tawv nqaij.

PVC zaj duab xis + HDF (Nqus tsim / tiaj tus txheej txheem thov):

RauPVC chav dej qhov rooj, PVC zaj duab xis yog txuas rau HDF nto los ntawm kub yaj nplaum los yog lub tshuab nqus tsev tsim. Kev ua haujlwm kub tsuas yog 80 ~ 120 degree, thiab lub siab tsis tshua muaj siab. Cov zaj duab xis txheej tsuas yog lub cev ua raws li txheej txheej sab nraud ntawm lub substrate, tsis muaj kev nkag mus tob ntawm cov nplaum txheej thiab cov fibers. Yog li, qhov pom tseeb ntawm qhov sib xyaw txheej no yog qhov tseem ceeb sib npaug ntawm HDF substrate nws tus kheej (kwv yees li 0.85 g / cm³). Txawm hais tias qhov ntom ntawm PVC zaj duab xis nws tus kheej yog kwv yees li 1.2 ~ 1.4 g / cm³, nws qhov kev pab cuam rau tag nrho qhov chaw ntom ntom yog qhov tsis txaus ntseeg vim nws cov tuab tuab heev (0.15 ~ 0.3 hli).

5-2. Kev soj ntsuam ntau ntawm Areal Density Difference thiab Sound Insulation

Ua ib qho kev siv 3.8mm tuab qhov rooj veneer ua piv txwv, qhov ntsuas qhov ntsuas thaj tsam loj (areal ntom) sib piv yog raws li hauv qab no:

Hom veneer	Areal ntom (kg / m²)	Kwv tij sib txawv
Melamine + HDF	4.2~4.8	Lub hauv paus
PVC zaj duab xis + HDF	3.5~3.9	Kwv yees li 0.6 ~ 0.9 kg / m² qis dua

Raws li txoj cai acoustic zoo, nyob rau hauv nruab nrab - mus rau - ntau zaus (1000 ~ 3150Hz), rau txhua txhua 1kg / m² nce nyob rau hauv qhov chaw ntom ntom, lub suab rwb thaiv tsev nce li ntawm 1.5 ~ 2dB. Yog li ntawd, nyob rau hauv tib lub core thiab thickness tej yam kev mob, ib tug pleev xim rau - dawb qhov rooj siv melamine kub- pressed qhov rooj ntawm daim tawv nqaij muaj peev xwm muaj ib tug suab rwb thaiv tsev theem (Rw) kwv yees li 1.5 ~ 2.5dB siab tshaj PVC-coated qhov rooj daim tawv nqaij. Rau siab - kawg qhov rooj ntsiag to aiming rau Rw Ntau dua lossis sib npaug rau 40, qhov sib txawv 2dB no tuaj yeem txiav txim ncaj qha seb cov khoom puas tuaj yeem hla qhov "40dB qhov pib ua haujlwm".
