Vim li cas fiberglass muaj lub suab zoo heev thiab txo cov suab nrov?

Kev ua tau zoo ntawmfiberglassyog txiav txim siab los ntawm nws cov tshuaj muaj pes tsawg leeg, kev tsim khoom, thiab cov qauv morphological. Ntawm nws cov khoom zoo heev, nws lub suab zoo dua thiab kev ua haujlwm rwb thaiv tsev ua rau nws yog cov khoom siv tseem ceeb rau kev tswj lub suab nrov thiab txhim kho acoustic kev nplij siab hauv cov chaw tsim khoom, cov cuab yeej siv, thiab tsheb thauj mus los, nrog rau kev siv dav heev.

 

01 Lub hauv paus ntawm Kev Ua Haujlwm Zoo Tshaj Plaws: Suab Absorption Coefficient

 

Lus Txhais: Lub suab nqus coefficient yog qhov taw qhia tseem ceeb rau kev ntsuas cov khoom siv lub suab nqus lub peev xwm. Nws sawv cev rau qhov sib piv ntawm lub suab lub zog nqus los ntawm cov khoom siv thiab tag nrho lub suab lub zog tshwm sim ntawm qhov chaw thaum lub suab nthwv dej tawm mus rau nws.

 

Tus nqi ntau: Lub suab nqus coefficient yog tus nqi ntawm 0 thiab 1.

 

Coefficient ntawm 0: Qhia tias cov khoom tsis nqus suab txhua, thiab tag nrho cov suab lub zog yog tshwm sim (xws li ib qho nyuaj, du pob zeb nto).

 

Coefficient ntawm 1: Qhia tau hais tias cov khoom absorbs suab tag nrho, thiab tag nrho cov suab zog yog absorbed (lub xeev zoo tagnrho, uas tsis muaj nyob rau hauv kev muaj tiag).

 

Qhov tseem ceeb: Qhov siab dua lub suab nqus coefficient, qhov muaj zog ntawm cov khoom muaj peev xwm nqus tau lub suab, uas yuav pab txo lub sij hawm reverberation nyob rau hauv ib qho chaw, txo suab nrov, thiab txhim kho lub suab clarity.

 

02 Suab Absorption Mechanism ntawm Fiberglass:

 

fiberglass cov ntaub ntawv (xws li iav ntaub plaub boards, felts, suab-absorbing ceilings, thiab lwm yam) muaj ib tug ntxeem tau, interwoven fiber ntau qauv. Thaum lub suab tsis nkag mus rau hauv cov khoom:

 

1. Lub suab nthwv dej nthuav tawm los ntawm cov kab tortuous ntawm cov fibers, tsim kev sib txhuam nrog cov fiber ntau.

2. Qhov kev sib txhuam no hloov lub zog ntawm lub zog (suab zog) ntawm lub suab tsis muaj zog mus rau lub zog hluav taws xob (tej me me ntawm cov cua sov).

3. Lub zog suab yog li noj thiab txo qis, ua tiav lub suab nqus.

03 Yam tseem ceeb cuam tshuam rau lub suab nqus kev ua haujlwm:

 

Lub suab nqus kev ua tau zoo ntawm fiberglass (nws qhov nqus coefficient thiab nws zaus -tus yam ntxwv nyob ntawm) tsis tas li tab sis cuam tshuam loj heev los ntawm nws lub cev cov qauv:

 

1. Tej qhov ntom ntom:

Txoj Cai Tseem Ceeb: Nyob rau hauv qhov tsim nyog, raws li qhov ceev ntawm cov ntaub ntawv fiberglass nce, nws lub suab nqus coefficient feem ntau qhia txog kev nce siab.

 

Yog vim li cas: Kev ceev ceev txhais tau hais tias muaj fiber ntau cov ntsiab lus nyob rau hauv ib chav tsev ntim, ua rau me thiab ntau tortuous pores ntawm cov fibers. Qhov no txhim kho qhov kev sib txhuam tsis zoo ntawm cov suab nthwv dej nthuav tawm hauv cov khoom siv, txhim kho kev nqus ntawm nruab nrab - mus rau - lub suab nrov zaus.

 

1. Balance Point: Ntau qhov ntom ntom tuaj yeem ua rau cov porosity tsawg dhau, ua rau nws nyuaj rau lub suab tsis yooj yim kom nkag mus rau cov khoom siv zoo, yog li cuam tshuam lub suab nqus. Yog li ntawd, muaj ib tug optimal density ntau yam.

 

2. Khoom Thickness:

Kev cuam tshuam tseem ceeb: Cov khoom tuab muaj qhov cuam tshuam tshwj xeeb rau qis - zaus suab nqus kev ua haujlwm.

 

Regularity: Ua kom tuab zoo txhim kho qhov nqus ntawm - zaus suab tsis zoo. Qhov no yog vim qhov tsawg- zaus suab tsis muaj qhov ntev wavelengths, yuav tsum tau lub suab tuab dua -absorbing txheej los muab cov suab txaus zog hloov pauv txoj kev thiab qhov chaw attenuation.

 

Siab -Frequency Impact: Thickness kuj txhim kho siab - zaus lub suab nqus, tab sis qhov nce hauv siab - zaus nqus coefficient feem ntau yog toj siab tom qab ncav cuag ib lub thickness.

 

3. Fiber taub:

Mechanism: Finer fibers muab qhov loj dua qhov chaw ntawm qhov chaw (surface area per unit mass or volume).

 

Cov nyhuv: Ntawm qhov ntom ntom, cov kab me me fiber ntau ua rau thaj chaw loj dua, ua rau lub sijhawm rau lub suab tsis sib cuag thiab rub tawm tsam cov fibers, uas feem ntau txhim kho lub suab nqus kev ua haujlwm, tshwj xeeb tshaj yog nyob rau nruab nrab - mus rau - ntau zaus.

 

Daim Ntawv Thov: Ultrafine iav ntaub plaub feem ntau pom zoo broadband suab haum kev ua tau zoo . 04 Daim Ntawv Thov Cheeb Tsam: Shapers of Tranquil Environments

 

Nrog nws cov suab nrov zoo heev (txo qis hauv tsev reverberation thiab suab nrov) thiab suab rwb thaiv tsev (txhim kho lub suab sib kis) cov khoom, cov ntaub ntawv fiberglass tau dav siv hauv:

 

Architectural Acoustics:

 

Phab ntsa thiab qab nthab kho lub suab nrov rau kev ua yeeb yam, kev hais kwv txhiaj, cov chaw kaw suab, chav sib tham, thiab cov chav hais lus (kev txhim kho suab zoo thiab txo cov suab nrov).

 

Ceiling systems rau chaw ua haujlwm, tsev so, tsev kho mob, thiab tsev kawm ntawv (txo cov suab nrov sab hauv tsev thiab txhim kho kev ceev ntiag tug thiab kev nplij siab).

 

Qhov chaw nyob hauv phab ntsa txhaws thiab hauv pem teb suab rwb thaiv tsev pads (thaiv cov suab nrov ntawm cov chav lossis hauv pem teb).

 

Industrial Noise Reduction:

 

Soundproof enclosures los yog suab -absorbing hauv ob sab phlu rau cov khoom siv fais fab xws li kiv cua, cua txias chav tsev, compressors, thiab generators.

Kev thauj mus los:

 

Cov vaj huam sib luag sab hauv, cov plag tsev, qab nthab, thiab cov phab ntsa hauv tsheb, siab - tsheb ciav hlau ceev, thiab lub dav hlau cabins (txo lub cav, cua, thiab lub suab nrov, txhim kho kev tsav tsheb thiab caij tsheb).

 

Suab rwb thaiv tsev rau lub nkoj cav chav thiab suab haum rau cov neeg caij tsheb cabins.

 

Cov khoom siv hauv tsev:

 

Kev tswj lub suab nrov rau cov khoom siv xws li lub tshuab nqus tsev, lub tshuab cua txias sab hauv tsev, thiab lub tshuab ntxuav tais diav.

 

Cov ntsiab lus

 

Fiberglass, los ntawm nws cov qauv ntxeem tau fiber ntau, muaj txiaj ntsig hloov suab lub zog rau hauv lub zog hluav taws xob, nthuav tawm suab nrov zoo heev. Nws cov nyhuv nqus suab (suab nqus coefficient thiab zaus tus yam ntxwv) tuaj yeem ua kom zoo dua los ntawm kev kho qhov tseem ceeb xws li volumetric ntom, tuab, thiab fiber ntau txoj kab uas hla kom tau raws li qhov xav tau ntawm kev tswj lub suab nrov hauv ntau zaus bands. Qhov no ua rau fiberglass yog ib qho khoom siv tseem ceeb hauv kev daws teeb meem suab nrov hauv kev tsim kho, kev lag luam, thiab kev thauj mus los thiab tsim kom muaj kev noj qab haus huv thiab xis nyob hauv acoustic. Kev nkag siab thiab siv cov kev sib raug zoo ntawm cov khoom no thiab cov yam ntxwv tsis zoo yog qhov tseem ceeb ntawm kev tsim cov suab nrov zoo thiab kev daws teeb meem.
