Niaj hnub no peb tab tom tham txog ntau yam kev ntsuas ntawmmineral fiber qab nthab board.

1.Ua ntej, peb tab tom tham txogNRC.NRC yog lub npe luv ntawm lub suab nrov txo Coefficient.Lub suab nrov txo coefficient yog hais txog qhov nruab nrab ntawm tus lej ntawm lub suab nqus coefficient ntawm cov khoom ntawm qhov nruab nrab zaus ntawm 250Hz, 500Hz, 1000Hz thiab 2000Hz, raug rau ob qhov chaw decimal, thiab tus lej kawg yog 0 lossis 5, uas tau hais los ntawm NRC .Obviously, qhov loj dua lub suab nrov txo coefficient, qhov zoo dua lub suab nqus cov nyhuv thiab qhov zoo ntawm acoustic kev ua tau zoo.

2.Qhov thib ob, nws yog CAC, Ceiling Attenuation Class.CAC Performance index yog ib qho kev ntsuas ntawm lub suab rwb thaiv tsev ntawm qhov chaw nyob ib sab.Qhov siab dua qhov CAC Performance index, qhov ua tau zoo ntawm acoustic.

3.Tom ntej no, nws yog lub teeb reflectivity.Mineral fiber ntau qab nthab board feem ntau yog siv hauv chaw ua haujlwm ib puag ncig.Rau cov chaw ua haujlwm, feem ntau ntawm cov ceilings yog xim dawb.Yog tias lub qab nthab muaj lub teeb pom kev siab, tag nrho cov chaw ua haujlwm yuav ci dua thiab txo qhov pom kev qaug zog.Kev siv lub sij hawm ntev ntawm lub qab nthab qis tuaj yeem ua rau pom kev qaug zog.

4. Qhov kawg yog qhov tsis kam ntawm cov av noo.Moisture resistance coefficient yog qhov tseem ceeb ntawm cov ntxhia fiber ntau qab nthab board zoo.Hauv qee qhov chaw, nws los nag thiab ntub dej txhua xyoo, yog li thaum xaiv qab nthab, peb yuav tsum xyuam xim rau kev siv cov ntxhia fiber ntau qab nthab board nrog siab RH.Tsis txhob xaiv cov khoom uas tsis tshua muaj RH rau pheej yig, thiaj li tsis txhob poob tom qab ntsia.

Cov ntsuas saum toj no tuaj yeem pab peb xaiv cov pob zeb hauv av fiber ntau qab nthab.Nws yog qhov tseeb tias cov pob zeb ntxhia wool feem ntau yog siv hauv cov tsev ua haujlwm thiab tuaj yeem pom txhua qhov chaw hauv chaw ua haujlwm.Ntawm qhov tod tes, lub qab nthab zoo li no tsis muaj teeb meem, ntawm qhov tod tes, nws muaj lub suab zoo nqus.Qhov tseem ceeb tshaj, cov khoom siv zoo li no pheej yig heev thiab tuaj yeem pab txo qis qhov project pob nyiaj siv.Nws yog cov khoom siv zoo nkauj zoo nkauj.
