Lub neej hauv lub nroog niaj hnub no muaj kev cuam tshuam tsis zoo rau kev noj qab haus huv. Kev ntxhov siab tas li, ib puag ncig tsis zoo thiab suab nrov tuaj yeem ua rau koj nyob tsis tswm. Ib qho kev ntxhov siab ntau ntxiv yog tshwm sim hauv kev puas siab puas ntsws ntawm tus neeg. Yog li ntawd, cov khoom siv suab nrov tau dhau los ua dav.
Cov khoom siv no feem ntau muaj cov ntaub txhuam cev thiab cov khoom ua npuas ncauj. Lawv, vim qhov porosity ntawm cov qauv, tsis xav txog lub suab, tab sis nqus nws rau hauv lawv tus kheej.
Scope of application
Muaj ntau cov ntaub ntawv pov thawj suab siv niaj hnub no rau kev lag luam, thaj chaw, kev lom zem thiab kev siv tsheb.
Nyob hauv tsheb, nrog rau cov khoom siv suab nrov, kev co-kev cais cov khoom feem ntau siv.
Hauv thaj chaw muaj kev lag luam, lub suab rwb thaiv tsev tau teeb tsa raws li GOSTs rau chav ua haujlwm.
Cov khoom siv suab nrov yog siv dav hauv kev tsim kho ntau yam kev ua kis las. Active txav thiab cuam tshuam thaum lub sij hawm ua hauj lwm ntawm cov khoom ua si thiab kev cob qhia nrogpob tsim tus yam ntxwv suab tom qab. Hauv cov chav no, cov khoom siv suab nrov-insulating thiab shock-absorbing yog siv, uas zoo nqus tau ntau yam nthwv dej.
Cov ntaub ntawv pov thawj suab yog siv rau cov chav ua haujlwm nrog cov khoom siv suab nrov. Cov no yog kaw studios, concert halls thiab xinemas.
Tsis tas li, cov khoom siv suab nrov yog siv rau cov tsev nyob. Thaum lub sij hawm tsim kho cov tsev niaj hnub, feem ntau tsis muaj suab nrov zoo heev. Yog li ntawd, nws yuav tsum tau siv cov kev ntsuas ntxiv los txhim kho nws txhawm rau ua kom muaj kev nyob zoo.
hom suab nrov thiab lawv qhov kev sib cais
Nyob rau hauv txhua rooj plaub, ib yam khoom siv yog siv. Nws qhov tsos yog nyob ntawm hom suab nrov uas tsim. Muaj peb hom suab nrov.
1. Lub suab nrov nrov yog tsim los ntawm ntau yam khoom siv hauv tsev, tsheb thiab kev sib tham nrov. Txhawm rau tiv thaiv lub suab zoo li no, ntau txheej soundproofing ntawm lub qab nthab yog qhov zoo. Cov no tuaj yeem yog cov ntaub ntawv mos mos xws li cov ntaub plaub mos mos thiab iav ntaub plaub. Lawv muab tso rau hauv lub thav duab system thiab hemmed nrog drywall. Nthuav lub qab nthab thiab acoustic cuav ceilings, uas muaj suab nrov-absorbing nyhuv thiab yog ib puag ncig tus phooj ywg kiag li, kuj tuaj yeem pab tawm tsam cov suab nrov hauv huab cua.
2. Cov suab nrov cuam tshuam tau hnov thaum raug rau hauv pem teb. Lawv tuaj yeem tshwm sim thaum kho cov haujlwm thiab cov menyuam yaus ua si. Nyob rau hauv cov ntaub ntawv no, suab nrov-absorbing qab nthab panels nrog ib tug tshwj xeeb kaw cell qauv yuav pab tau. Ntau yam khoom ntxeem tau kuj siv, tab sis lawv yuav tsum tau muab tso rau hauv pem teb, ceslub qab nthab ntawm chav tsev qis yuav tiv thaiv lub suab nrov. Rau qhov no, cork, rubberized substrates, cov khoom sib xyaw lossis polystyrene ua npuas ncauj tuaj yeem siv. Qhov tseem ceeb tshaj plaws yog tsim kom muaj lub hauv paus ntab uas muaj ob peb txheej.
3. Cov qauv suab nrov yog tsim thaum lub ntsiab load-bearing qauv txuas nrog yam tsis siv cov khoom siv suab nrov. Tom qab ntawd cov nyhuv suab yuav kis thoob plaws hauv lub tsev, tsis hais qhov twg los ntawm qhov tshwm sim. Cov suab nrov zoo li no nyuaj dua rau kev daws teeb meem. Txhawm rau tiv thaiv cov pob qij txha ntawm cov khoom siv thauj khoom, nws yog qhov yuav tsum tau yuav cov khoom siv gasket. Nws tuaj yeem yog cov khoom siv elastomeric, fiberglass lossis vibroacoustic sealant.
khoom siv suab nrov
txhawm rau tshem tawm ntau lub suab nrov hauv peb cov lus qhia - qab nthab, phab ntsa thiab hauv pem teb - siv ntau yam suab nrov-absorbing khoom. Rau cov phab ntsa, xws li kev tiv thaiv yog qhov tseem ceeb tshwj xeeb. Piv txwv li, nyob rau hauv vaj huam sib luag vaj tse, lub ntsiab lub suab nrov nkag mus rau hauv lub phab ntsa, txawm lub ntsiag to quaj ntawm ib tug me nyuam yog hnov. Qhov no ua rau muaj kev tsis sib haum xeeb thiab tsis sib haum xeeb nrog cov neeg nyob ze. Yog li ntawd, cov suab nrov-absorbing panels feem ntau yog siv rau cov phab ntsa soundproofing.
Nyob ntawm qib ntawm kev nruj ntawm cov khoom, lawv txawv:
- Cov ntaub ntawv mos rau rwb thaiv tsev. Lawv yog ua los ntawm paj rwb ntaub plaub, iav ntaub plaub, muaj los yog jute. Kev nqus coefficient yog 70%. Advantage – low bulk density – 70 kg/m3;
- Cov ntaub ntawv Semi-rigid. Qhov no yog compressed ntxhia ntaub plaub los yog fiberglass nyob rau hauv daim ntawv ntawm daim hlau. Ob qho khoom sivcellular hauv cov qauv (piv txwv li, polyurethane ua npuas ncauj). Suab rwb thaiv tsev coefficient - 50-75%. Qhov ntom ntom - 80-130 kg / m 3;
- khoom siv tawv. Lawv yog raws li granulated los yog tshem tawm cov ntxhia wool. Lub suab nqus - 50%. Qhov ntom ntom - 400 kg / m 3.
Sandwich dampening
Cov khoom siv suab nrov hauv cov tshuab no muaj ntau yam. Ntawd yog, tus qauv tsim muaj cov txheej txheem nyuaj rau sab nraud, ntom ntom thiab mos sab hauv.
Cov khaubncaws sab nraud tuaj yeem ua los ntawm cov slabs hauv pem teb lossis cov phab ntsa ntub dej. Nyob rau hauv cov ntaub ntawv no, lub suab rwb thaiv tsev yog ncaj qha proportional rau lawv ceev. Cov khoom siv ntom ntom ua haujlwm ua lub suab absorber. Qhov no yog cov uas twb hais lawm iav ntaub plaub los yog lwm yam ntaub ntawv nrog ib tug fibrous qauv. Lub thickness ntawm cov khoom, raws li txoj cai, tsis tsawg tshaj li 5 cm.
Dab tsi yog cov khoom siv suab nrov
Muaj ntau cov khoom npaj ua suab nrov-absorbing. Piv txwv li, panels. Lawv yog siv rau txhua yam kev tiv thaiv cov ntxaij vab tshaus thiab rau soundproofing chav tsev. Lub vaj huam sib luag muaj ib tug ncej, nyob rau hauv uas muaj ib tug tshwj xeeb suab nrov-absorbing insert. Cov ntxig no muaj cermet lossis txhuas ua npuas ncauj suab nrov absorbers.
Lub laj kab nrov nrov tau nthuav tawm hauv arsenal ntawm cov khoom siv rau kev sib ntaus suab nrov. Lawv yog ua los ntawm pob zeb, corrugated board, thiab tuaj yeem ua vaj tse pob zeb. Monolithic laj kab yog ua los ntawm cov blocks, pob zeb lossis cib. Cov laj kab laj kab yog ntsia tau sai heev thiab muaj zog ua haujlwm. Lawv tuaj yeem ua los ntawm cov pob zeb zoo nkauj. Lub suab nrov-absorbing zog ntawm ib lub laj kab ua los ntawm corrugated board tsis muaj zog dua li pob zeb lossis monolithic. Tab sis lawv pheej yig dua.
Ib txoj hauv kev zoo los tshem tawm cov suab nrov hauv chav tsev yog lub qhov rooj uas muaj suab nrov. Lub qhov rooj sab hauv hauv chav tsev ua lub thermal thiab suab insulator. Kev siv lub suab pov thawj zoo ntawm cov qauv qhov rooj muaj cov hauv qab no tseem ceeb:
- Cov khoom siv qhov rooj: iav inserts, khoom ntoo, canvas nrog muab tub lim.
- Hniav tsim: hinged, zawv zawg, folding.
- Qhov nruj ntawm lub qhov rooj module, uas tsim qhov tsim nyog nruj.
CV
Muaj ntau cov khoom siv suab nrov tshem tawm hauv khw niaj hnub no. Cov no yog cov khoom siv hauv tsev thiab sab nraum zoov. Yog li ntawd, nws yog ib qho tsim nyog yuav tau coj lub luag haujlwm mus kom ze rau qhov teeb meem ntawm lub suab rwb thaiv tsev. Tom qab tag nrho, xaiv kom raug thiab teeb tsa cov khoom siv suab nrov tuaj yeem tswj tau qhov chaw nyob ntsiag to thiab xis nyob hauv txhua chav.
