Kev Ntsuas Kev Ua Haujlwm Thiab Cov Qauv Rau PET Filament Sound Insulation Felt

Kev ntsuas kev ua tau zoo yog ib kauj ruam tseem ceeb hauv kev ntsuas lub suab rwb thaiv tsev zoo thiab ua haujlwm ntev ntawm PET filament suab rwb thaiv tsev. Cov kev ntsuas tseem ceeb muaj xws li lub suab rwb thaiv tsev kev ua tau zoo (kev sib kis tsis tau), kev soj ntsuam cov lus teb zaus, cov khoom siv ntom ntom, thickness uniformity, suab nqus coefficients, acoustic impedance, thiab suab rwb thaiv tsev spectrum tsom xam. Ntev-lub sij hawm thiab kev ntsuas kev ua tau zoo tshwj xeeb suav nrog kev ua haujlwm ntev, thermal aging kuj, hygrothermal stability, kub hloov pauv (xws li, thermal conductivity, thermal expansion coefficient, qis- kub brittleness), thiab cov yam ntxwv resilience (xws li, tus nqi rov qab, compression tas li).
Cov qauv ntsuas cuam tshuam suav nrog cov qauv thoob ntiaj teb xws li ASTM E90 thiab ISO 10140 series, nrog rau cov qauv hauv Suav teb xws li GB / T 19889.3 thiab GB 50009. Qee cov khoom ua raws li cov qauv tshiab hauv tebchaws hais txog cov kev xav tau ntawm lub suab rwb thaiv tsev. Cov khoom siv uas siv ntau tshaj plaws suav nrog acoustic test chambers, microphones, suab ntsuas ntsuas, teeb liab generators, ib puag ncig aging chambers, universal material testers, thiab thermal conductivity testers.
