Kev Tshawb Fawb Txog Kev Txo Suab Nrov Ntawm Cov Compressors Hloov Pauv Zaus Siv Basalt Fiber-Felt Composite
I. Keeb Kwm thiab Qhov Tseem Ceeb ntawm Kev Tshawb Fawb
Kev ua qias tuaj ntawm suab nrov ib puag ncig tau dhau los ua teeb meem tseem ceeb uas cuam tshuam rau tib neeg kev noj qab haus huv thiab lub neej zoo, nrog rau cov khoom siv hauv kev lag luam (piv txwv li, cov tshuab compressor uas hloov pauv zaus) yog qhov tseem ceeb uas ua rau muaj kev cuam tshuam. Cov ntaub ntawv nqus suab nrov ib txwm muaj (piv txwv li, cov ntaub paj rwb) ua rau muaj kev ua haujlwm tsawg hauv cov zaus siab thiab yooj yim rau cov yam ntxwv ib puag ncig xws li kub. Cov fiber basalt, ib yam khoom siv inorganic ua tau zoo nrog cov qauv porous thiab cov khoom zoo acoustic, tau tshwm sim ua lwm txoj hauv kev zoo tshaj plaws rau kev tswj suab nrov.
II. Cov yam ntxwv thiab kev tsim khoom ntawm Basalt Fiber
1. Cov Khoom Siv Zoo
Cov fiber basalt, yog ib qho ntawm plaub lub fibers tseem ceeb hauv Suav teb, ua rau lub suab nqus tau zoo dua los ntawm kev hloov cov cua co hauv nws cov qhov hws mus ua lub zog thermal. Nws qhov ceev thiab cov qauv zoo tshaj plaws ua rau nws zoo dua li cov paj rwb rau kev nqus suab nrov dav dav.
2. Txheej Txheem Tsim Khoom
Cov kws tshawb fawb los ntawm Qingdao University tau tsim ib daim ntaub sib xyaw ua ke los ntawm kev sib xyaw cov fibers basalt nrog cov fibers paj rwb. Los ntawm kev ua kom zoo dua qhov sib piv thiab cov txheej txheem ua tiav, cov khoom sib xyaw ua ke tau txais kev ywj pheej siab thiab kev ua tau zoo ntawm lub suab. Cov kev sim tau ua pov thawj tias nws txo qis suab nrov ntawm cov zaus siab (85 Hz) piv rau cov zaus qis (45 Hz), nrog rau kev ua haujlwm zoo dua hauv qhov chaw kub qis.
III. Kev Tsim Qauv Sim thiab Kev Tshawb Fawb Txog Kev Txo Suab Nrov
1. Cov Xwm Txheej Kev Ntsuas
Cov kev sim tau soj ntsuam cov suab nrov nyob rau hauv ntau yam kev ua haujlwm (kub, zaus) ntawm lub tshuab compressor uas hloov pauv tau, uas npog cov zaus qis (45 Hz), nruab nrab (65 Hz), thiab siab (85 Hz). Kev sib piv kev ua tau zoo tau ua ntawm cov ntaub basalt fiber thiab cov ntaub paj rwb ib txwm muaj.
2. Cov Txiaj Ntsig Tseem Ceeb
Kev Ua Zoo Tshaj Plaws ntawm Zaus Siab: Lub basalt fiber ntautau txais lub suab nqus coefficient ntawm 0.85-0.95 ntawm cov zaus siab, ze li ntawm kev ua tau zoo ntawm phenolic Iav Fiber xav tias.
Kev Nyob Ntawm Qhov Kub: Nws lub peev xwm txo suab nrov tau zoo dua ntawm qhov kub qis dua, thaum cov ntaub ntawv ib txwm poob qis thaum kub siab.
Kev Ua Tau Zoo Tag Nrho: Cov khoom sib xyaw ua ke basalt tau txhim kho kev txo suab nrov los ntawm ~ 20% piv rau paj rwb uas muaj tib lub zaus, ua kom txo tau suab nrov dav dav los ntawm kev co ntawm lub compressor thiab cua.
IV. Kev sib piv nrog cov thev naus laus zis txo suab nrov ib txwm muaj
1. Kev Ua Haujlwm ntawm Cov Khoom Siv
Txawm hais tias cov ntaub ntawv ib txwm muaj (piv txwv li, cov iav ntaub plaub) muaj cov coefficients nqus tau zoo (0.90–0.99), lawv raug kev txom nyem los ntawm kev laus thiab kev txhawj xeeb txog ib puag ncig. Cov ntaub basalt fiber phim lawv cov kev ua tau zoo acoustic thaum muab kev tiv thaiv cua sov zoo dua thiab kev phooj ywg ib puag ncig.
2. Cov Xwm Txheej Thov
Tsis zoo li cov kev daws teeb meem passive (piv txwv li, enclosures, mufflers), basalt fiber felt tuaj yeem qhwv ncaj qha rau ntawm compressors lossis koom ua ke rau hauv cov qauv soundproof, ua kom yooj yim rau kev kho dua tshiab. Piv txwv li, hauv HVAC systems, nws txo qis qhov kev sib kis suab nrov qis los ntawm cov kav dej tooj liab mus rau hauv qhov chaw sab hauv tsev.
V. Tej Yam Uas Yuav Tau Ua Thiab Tej Kev Cov Nyom
1. Kev Siv Hauv Tsev thiab Kev Lag Luam
Cov ntaub basalt fiber muaj kev cia siab rau cov tshuab compressors hauv kev lag luam, cov tshuab cua txias, thiab ntau ntxiv. Ua ke nrog cov qhov rooj kaw, nws tuaj yeem txo cov suab nrov ntawm lub Hoobkas kom qis dua 45 dB, ua tau raws li cov qauv ib puag ncig.
2. Kev Txhim Kho Kev Txawj Ntse
Kev Txhim Kho Zaus Qis: Cov qauv tsim sib xyaw (piv txwv li, cov qauv sandwich) tuaj yeem txhim kho kev nqus zaus qis.
Txo Tus Nqi: Kev nthuav dav ntawm kev tsim khoom yog qhov tseem ceeb rau kev txo cov nqi, vim tias cov fiber basalt tseem kim.
VI. Xaus Lus
Cov khoom sib xyaw ua los ntawm basalt fiber-felt, nrog rau cov qauv zoo tshaj plaws thiab cov txheej txheem tsim khoom, qhia tau tias muaj peev xwm tswj tau suab nrov ntau zaus hauv cov compressors hloov pauv zaus. Kev tshawb fawb yav tom ntej yuav tsum tsom mus rau kev ruaj khov nyob rau hauv cov xwm txheej ua haujlwm nyuaj thiab kev sib koom tes nrog lwm cov thev naus laus zis txo suab nrov kom dav dua.
