Cov dej noo- pov thawj Board Core Functions

Lub npe "moisture-resistant board" qhia ncaj qha rau nws cov haujlwm tseem ceeb: tiv thaiv lub cev puas tsuaj los ntawm qhov chaw ntub dej. Txhawm rau kom nkag siab txog nws cov khoom muaj pes tsawg leeg, ib tus tsis tuaj yeem tsuas yog nres ntawm qhov kev piav qhia ntawm "moisture-} tiv taus," tab sis yuav tsum txheeb xyuas los ntawm ob qib sib cuam tshuam ntawm "barrier" thiab "structure" hauv cov ntaub ntawv science. Cov dej noo- cov boards tiv taus tsis yog tsim los ntawm ib qho, tag nrho cov tshuaj tshiab; lawv cov ntsiab lus yog nyob rau hauv kev hloov kho ntawm cov khoom siv ntoo uas siv los ua kom lawv muaj peev xwm tiv thaiv kev tawm tsam ntawm cov kua dej thiab dej vapor. Qhov kev hloov kho no feem ntau yog nyob ib ncig ntawm ob lub hom phiaj tseem ceeb: ua ntej, thaiv txoj hauv kev ntawm cov dej noo nkag; thiab thib ob, ntxiv dag zog rau cov qauv kev ruaj ntseg ntawm cov khoom nws tus kheej nyob rau hauv cov av noo.

Los ntawm qhov kev xav ntawm kev thaiv txoj hauv kev ntawm cov dej noo, noo noo- tiv thaiv kev kho mob ua ntej ua rau lub substrate ntawm lub rooj tsavxwm. Cov feem ntau engineered ntoo substrates, xws li particleboard thiab nruab nrab - ntom fiberboard (MDF), yog tsim los ntawm cov ntoo fibers los yog ntoo chips. Cov ntoo no lawv tus kheej yog hygroscopic, thiab suav tsis txheeb micropores tsim thaum lawv tau sib koom ua ke nyob rau hauv qhov kub thiab siab siab ua raws li ntuj tsim rau kev nkag mus rau cov dej noo.
