1. Cov Khoom Siv Cov Khoom Siv Txiav Txim Siab Rwb Thaiv Tsev
Cov khoom siv tseem ceeb ntawm PVC tiv thaiv kev sib tsoo yog polyvinyl chloride (PVC). Txawm hais tias nws qhov ntom ntom yog qis dua li ntawd ntawm cov khoom ntoo lossis cov hlau ua kom zoo nkauj ntub dej tsim hluav taws xob (xws li filling honeycomb panels lossis suab rwb thaiv tsev paj rwb thaiv sab hauv). Kev sim cov ntaub ntawv qhia tau tias PVC tiv thaiv cov rooj sib tsoo nrog cov qauv tuab ({mm 3}} mm yuav ua tiav lub suab rwb thaiv tsev ntawm {}} decibels. Qhov no txhais tau tias thaum lub suab nrov sab nraum zoov yog 70 decibels (sib npaug rau lub suab nrov), lub suab nrov hauv nroog tuaj yeem raug txo qis dua 45 daim ntawv sau tseg hauv lub tsev qiv ntawv ib puag ncig).

2. Fealing qauv txhim kho cov suab nrov txo cov nyhuv
Piv nrog cov qhov rooj zoo tib yam, qhov kom zoo ntawm PVC tawm tsam cov qhov rooj nyob hauv lub systematic sealing seading tsim:
EPDM Sealing cov kab txaij yog siv ib ncig ntawm lub qhov rooj thav duab los ua ib qho kev thaiv huab cua huab cua tom qab kaw
Hauv qab tsis siv neeg Lifting Seev Cev Sawb Fills qhov sib txawv hauv av
Ntau-qhov chaw xauv tes ua haujlwm kom ntseeg tau tias lub qhov rooj lub qhov rooj yog tusyees convivered
Cov qauv uas tag nrho tuaj yeem thaiv tau ntau dua 90% ntawm cov suab nrov high-zaus (xov tooj ringtones), thiab tseem muaj zog tsis muaj zog (xws li footsteps).

3. Qhov cuam tshuam ntawm kev saib xyuas ntawm lub suab rwb thaiv tsev ua haujlwm
Txhawm rau kom muaj suab zoo rwb thaiv tsev ntev ntev, thov saib xyuas rau cov hauv qab no:
Txheeb xyuas cov elasticity ntawm cov sealing sawb txhua lub quarter thiab hloov chaw laus nyob rau lub sijhawm
Zam kev sib tsoo muaj zog uas yuav ua rau muaj kev cuam tshuam ntawm lub qhov rooj qauv
Ntxuav cov cheeb tsam khiav tsis tu ncua kom tiv thaiv cov plua plav ntxiv los ntawm kev cuam tshuam cov qib ntawm kaw
Nrog rau kev saib xyuas kom tsim nyog, PVC tawm tsam sib tsoo tuaj yeem tswj lub suab ruaj khov rwb thaiv tsev rwb thaiv tsev ua tau zoo rau {1}} xyoo.
