Nqe Lus Nug 1: Lub suab rwb thaiv tsev ntawm ib daim ntawv galvanized steel zoo li cas?
Lub suab rwb thaiv tsev kev ua tau zoo ntawm ib qho - txheej nyias steel daim ntawv yog qhov tsis muaj zog, tshwj xeeb tshaj yog nyob rau hauv kev sib cais qis - mus rau - nruab nrab - nrov nrov xws li cov neeg niaj hnub lub suab thiab cov khoom siv ua haujlwm. Nws xa suab tau yooj yim, ib qho tshwm sim uas feem ntau hu ua "drumming effect," thiab nws tseem yuav tsim lub suab nrov "pitter-patter" thaum nws los nag.
Nqe Lus Nug 2: Dab tsi yog qee qhov kev paub daws teeb meem los txhim kho nws lub suab rwb thaiv tsev?
Tus yuam sij rau kev txhim kho yog nyob rau hauv kev hloov ib qho qauv, feem ntau yog los ntawm cov hauv qab no:
Sau nrog suab-absorbing cov ntaub ntawv: Qhov no yog txoj kev tseem ceeb tshaj plaws. Pob zeb wool los yog iav ntaub plaub, los yog lwm yam suab- absorbing cov ntaub ntawv, yog ntim ntawm ob txheej xim -coated steel los xij los tsim ib tug composite sandwich vaj huam sib luag. Cov qauv ntxeem tau ntawm pob zeb wool / iav ntaub plaub tuaj yeem nqus tau ntau lub zog ntawm lub zog los ntawm kev sib txhuam thiab kev sib hloov cua sov, ua tiav cov suab nrov txo coefficient (NRC) ntawm 0.7-0.9. Txoj kev no feem ntau siv nrog 100mm tuab nplooj ntawv, thiab ntsuas qhov hnyav ntawm lub suab rwb thaiv tsev (RW) tuaj yeem ncav cuag 30-35dB.
Kev kho perforation: Perforations ntawm ib txoj kab uas hla thiab ntom yog xuas nrig ntaus rau hauv cov xim -coated steel ntawv, thiab ces ua ke nrog suab- nqus cov ntaub ntawv los yog huab cua txheej nyob rau tom qab, zoo absorbing suab nrov. Piv txwv li, ib qho kev xyaum yog xuas nrig ntaus 4 hli qhov nyob rau hauv lub vaj huam sib luag, ua ke nrog ib tug siab - ceev (20%) perforation tus nqi thiab pob zeb wool nyob rau tom qab; Txawm li cas los xij, hauv kev siv tswv yim, ua tiav lub suab- cov vaj huam sib luag nqus tau zoo tiv thaiv los nag thiab lub suab nrov, thiab ib qho - txheej hlau suab thaiv tuaj yeem ua tiav lub suab rwb thaiv tsev ntawm ≥30dB.
Siv lub suab-absorbing coatings: Siv tshwj xeeb damping coatings (xws li elastic coatings zoo li polyurethane) rau saum npoo ntawm cov xim -coated steel ntawv yuav suppress steel phaj kev co, txo cov suab nrov ntawm qhov chaw, thiab yog tshwj xeeb tshaj yog haum rau kev daws ib nrab ntawm - mus rau -high zaus xws li footsteps tsis cuam tshuam.
Nqe Lus Nug 3: Puas muaj qhov tshwj xeeb rau kev sib piv cov txiaj ntsig ntawm cov kev daws teeb meem no?
Cov lus hauv qab no qhia txog cov ntaub ntawv kev ua haujlwm ntawm lub suab rwb thaiv tsev rau cov kev daws teeb meem sib txawv, muab kev nkag siab ntau dua:
Suab rwb thaiv tsev tshuaj|Ntsiab Parameters/Technology|Ntsuas suab rwb thaiv tsev nyhuv
Tib - txheej Galvanized Coated Steel Chev|Thickness 0.3 -0.8 hli|Tsawg suab rwb thaiv tsev nyhuv, tshwj xeeb tshaj yog pom tau rau cov suab nrov qis thiab nruab nrab
Perforated kho mob + Suab Absorbing paj rwb|Pore txoj kab uas hla Φ5-8mm, qhib tus nqi 20%-30%|Noise Reduction Coefficient (NRC) 0.7-0.9
Xim Hlau Pob Zeb Wool Sandwich Vaj Huam Sib Luag|Configuration: Ob txheej xim hlau phaj, pob zeb wool filling nyob rau hauv nruab nrab, thickness 100mm|Ntsuas suab rwb thaiv tsev (RW) 30-35 dB
Perforated Hlau Suab Barrier|Tib - txheej perforated hlau phaj + rov qab suab nqus|Ntsuas suab rwb thaiv tsev ≥30 dB
Nqe Lus Nug 4: Galvanized xim-coated steel coils feem ntau yog siv los ua suab nrov rau txoj kev loj. Lawv qhov zoo yog dab tsi?
Vim tias lawv tuaj yeem ua tiav thiab ua ke kom ua tiav cov suab nrov txo kev ua haujlwm zoo, lawv tau siv dav hauv txoj kev loj suab teeb meem. Lawv qhov zoo yog qhov tseem ceeb:
Kev sib xyaw ua ke yooj yim: Lawv tuaj yeem yooj yim ua ke nrog cov ntaub ntawv xws li pob zeb wool / iav ntaub plaub kom ua tiav ob qho txiaj ntsig ntawm "suab rwb thaiv tsev + suab nqus."
Tus nqi siab -kev ua tau zoo: Piv rau cov hlau tsis muaj steel thiab txhuas daim hlau, tus nqi qis dua, thaum tseem ua tau raws li qhov yuav tsum tau muaj kev tiv thaiv.
Muaj zog thiab ruaj khov: Lawv tuaj yeem tiv taus cov teeb meem sab nraum zoov xws li kev cuam tshuam ntawm tsheb thiab cua siab, thiab raug kho nrog txhua yam - huab cua tiv thaiv corrosion. Galvanized steel ntawv ntawm qib Q235B, tom qab txheej, tuaj yeem siv rau hauv qhov chaw xws li kev loj.
Nqe Lus Nug 5: Cov ntsiab lus ntawm kev teeb tsa dab tsi txiav txim siab lub suab rwb thaiv tsev tiag tiag ntawm cov xim -coated steel ntawv?
Suab rwb thaiv tsev zoo los yog tsis ua hauj lwm feem ntau hinges ntawm cov ntsiab lus. Ua tib zoo mloog cov hauv qab no thaum tsim kho:
Sealing pob qij txha: Qhov no yog qhov tseem ceeb tshaj plaws. Txhua qhov sib txawv tuaj yeem ua rau lub suab rwb thaiv tsev tsis ua haujlwm. Xyuas kom zoo sealing ntawm cov pob qij txha siv lub siab strips, sealant, thiab lwm yam, los tiv thaiv "suab luv luv circuits."
Zuag qhia tag nrho sealing: xyuas kom cov ntxhua khaub ncaws ntawm lub mounting screws yog lawm. Kev sib khi ntawm cov pob qij txha ntawm daim ntawv thiab lub qhov rooj / qhov rooj qhib yuav tsum nyob rau hauv qhov chaw los tsim kom muaj qhov chaw kaw.
Pav ca installation: Ib theem yuav tsum tau siv los xyuas kom meej cov ntawv yog ntsia tiaj tus, tsis txhob muaj unevenness los yog deformation. Qhov no ncaj qha cuam tshuam rau lub suab rwb thaiv tsev nyhuv thiab kev zoo nkauj ntawm cov khoom siv.
Tiv thaiv kom tsis txhob ya raws: Yog hais tias sab hauv yog ntim nrog suab - cov khoom nqus dej, xyuas kom cov ntawv tsis deformed los yog puas thiab cov pob qij txha raug kaw kom tsis txhob ya raws los yog dej nkag mus thiab ua rau cov qauv ntawm lub suab ntxeem tau - absorbing cov khoom, ua rau txo qis suab rwb thaiv tsev kev ua tau zoo.
