Moisture -Cov ntaub ntawv pov thawj MDF Acoustic Phab ntsa Panels

Yuav ua li cas paub qhov zoo ntawm MDF Sound Absorbing Panels

MDF substrate ncaj qha txiav txim siab qhov ntev thiab ib puag ncig tus phooj ywg ntawm cov vaj huam sib luag, thiab yog tus yuam sij rau kev sib txawv zoo. Hais txog qhov ntom ntom, siab - cov vaj huam sib luag zoo feem ntau muaj qhov ntom ntom ntawm 800-850 kg/m³, tsis muaj qhov dents thaum nias thiab tiv thaiv deformation thaum khoov. Low-priced, inferior products often have a density below 600 kg/m³, are mostly made from compressed wood chips, and are prone to cracking and moisture absorption. Hais txog ib puag ncig tus phooj ywg, ua ntej cov khoom lag luam nrog formaldehyde emissions Tsawg dua lossis sib npaug li 0.05 mg / m³, ua tau raws li cov qauv hauv tsev thiab thoob ntiaj teb ib puag ncig zoo xws li E0 thiab CARB P2, zam cov khoom uas muaj urea ntau dhau - formaldehyde resin cov ntsiab lus uas tuaj yeem ua rau muaj ntxhiab tsw. Tsis tas li ntawd, xyuam xim rau cov txheej txheem kho substrate. Rau kev ya raws- cov ntaub ntawv pov thawj, xaiv cov substrates kho nrog cov tshuaj tiv thaiv dej noo; rau thaj chaw pej xeem, xyuas kom cov substrate muaj qhov ntsuas hluav taws kub ntawm B1 lossis siab dua, qhov twg tsuas yog cov pa roj carbonization tshwm sim tom qab hlawv, tsis muaj qhov qhib nplaim taws.
