Internal Duct Acoustic rwb thaiv tsev Liner
Internal duct acoustic rwb thaiv tsev Liner yog engineered rau huab cua -sab installation nyob rau hauv HVAC ductwork. Nws absorbs ducts - ua suab nrov los ntawm cov kiv cua thiab airflow thaum xa cov thermal rwb thaiv tsev kom qis zog poob thiab tiv thaiv condensation.
Kev yuav khoom yuav tsum muaj kev sib txuam ntawm kev tsim kho lub cev, cov ntaub ntawv hauv chav kuaj acoustic, kev ntsuas hluav taws kub, huab cua-sab durability, thermal zog, thiab qhov ntev kam rau ua ncaj qha rau qhov project specifications.

Core Performance Criteria
Acoustic Absorption:Kev ntsuam xyuas los ntawm cov zaus band thiab Noise Reduction Coefficient (NRC). Cov ntaub ntawv xeem yuav tsum ua raws li qhov tseeb installation thickness thiab mounting txoj kev (xws li, Hom A mounting).
Cua -Side Durability:High - Cov kab hluav taws xob nrawm yuav tsum muaj kev ncaj ncees ntawm qhov chaw kom tiv thaiv kev yaig fiber ntau thiab tuav lub ntsej muag adhesion dhau lub sijhawm ua haujlwm ntev.
Tshwj xeeb Hygiene Environments:Cov chaw xws li tsev kho mob, chav huv huv, thiab cov chaw ua zaub mov yuav tsum tsis muaj - ntxeem tau ntsej muag, tiv thaiv - microbial kev loj hlob tsis kam (ASTM C1338), thiab ntawv pov thawj qis -VOC ua raws.
Kauj Ruam -los ntawm - Kauj Ruam Engineering Xaiv Phau Ntawv Qhia
Daim ntawv qhia Acoustic Requirements:Match attenuation xav tau thoob plaws octave bands tiv thaiv kiv cua nrov profiles.
Xam xam Internal Clearance:Tus account rau lub liner thickness, raws li mounting nyob rau hauv thiaj li yuav ua tau zoo duct cross-sectional cheeb tsam thiab ua rau kom huab cua tshaj tawm.
Txheeb xyuas Air Velocity Limits:Xyuas kom lub kaw lus tsim kev tshaj tawm tsis tshaj qhov kev lees paub UL 181 huab cua yaig txwv ntawm cov khoom.
Confirm Kev Ua Raws Cai:Txheeb xyuas cov qauv kev nyab xeeb hluav taws (ASTM E84 Class A lossis EN 13501-1) thiab cov cai hauv cheeb tsam ib puag ncig.
Txiav txim siab txoj kev Fastening:Qhia meej rau cov nplaum sib xws, ntug- txheej sealants, thiab mechanical pin ntom ua ntej kev teeb tsa.

FAQ
Q: Dab tsi yog lub hom phiaj tseem ceeb ntawm lub hauv paus acoustic rwb thaiv tsev liner?
A: Nws cov kab sab hauv ntawm lub qhov cua tshuab kom nqus cov suab nrov los ntawm cov kiv cua thiab cua txav thaum muab thermal rwb thaiv tsev los tswj qhov kub thiab txias.
Q: Kuv yuav txiav txim siab qhov raug rwb thaiv tsev thickness li cas?
A: Kev xaiv nyob ntawm lub hom phiaj suab nrov attenuation frequencies, qhov chaw txwv nyob rau hauv lub duct, yuav tsum tau thermal R- tus nqi, thiab tso cai rau lub siab poob.
Cov acoustic liner no puas tuaj yeem siv rau hauv siab -ceev duct systems?
Yog lawm, yog tias cov khoom tau dhau los kuaj huab cua yaig (xws li UL 181) thiab raug ntsuas rau huab cua nrawm sib npaug lossis ntau dua li qhov siab tshaj plaws.
Q: Hauv ob sab phlu cuam tshuam li cas ntawm cov kav dej?
A: Sab hauv hauv ob sab phlu txo qhov chaw sab hauv ntawm lub ductwork. Kev tsim kev suav yuav tsum suav rau cov kab tuab kom tswj tau qhov xav tau airflow ntim thiab siab zoo li qub.
Q: Cov ntaub ntawv dab tsi yog muab rau kev pom zoo qhov project?
A: Cov pob ntawv xa tawm txheem suav nrog TDS, SDS, acoustic absorption test reports, fire Safety certificate, UL 181 air erosion test data, thiab batch quality compliance certificates.
