Fiberboard, tseem hu ua tus neeg ntom ntom, yog ib tus txiv neej -}}}} ill fiber ntau los yog lwm cov khoom siv roj fiber ntau. Fiberboard muaj cov yam ntxwv zoo thiab ua kom zoo thiab yog siv dav hauv kev lag luam xws li rooj tog tsim, tsim kho kom zoo, thiab kho kom zoo nkauj. Niaj hnub no, Cheng Cheng yuav muab cov lus qhia luv luv rau fiberboard fiberboard thiab nws cov qauv hauv tebchaws.
Fiberboard tuaj yeem muab faib ua cov mos fiberboard, semi {} {{{{{{}} kub fiberboard), thiab tawv fiberboard nyuaj raws li ntom ntom ntom. Nruab nrab - densab fiberboard, ua cov khoom siv homogeneous, yog siv dav ua ib qho ntoo lwm txoj. Nws muaj tus nqi qis, kev ua kom yooj yim, thiab siv tus nqi siab, ua rau nws muaj kev lag luam ntau dua li ntoo ntuj. Lub Tebchaws Txheej Txheem "GB / T 11718 {{{}}}}}}}}}}}}} Cov ncauj lus qhia nruab nrab rau nruab nrab- densab fiberboard khoom. Tus qauv txhais tau nruab nrab- densital fiberboard (ua kom muaj cov fiber ntau, ua tiav nrog cov fiber ntau, nrog rau cov khoom siv hluav taws xob, nrog rau ntau yam ntawm 0.65 g / cmà rau 0.80 g / cm³. Tus qauv no feem ntau siv los ua kom qhuav-} txheej txheem MDF. Nyob ntawm qhov kev npaj siv, MDF tuaj yeem raug categorized rau plaub hom: General- hom phiaj, ntim-kabmob, thiab kev tsim kho. Cov cai siv tshwj xeeb thiab cov lej ntaus ntawv yog qhia hauv qab rooj hauv qab no.
Qhov ua tau zoo rau MDF feem ntau yuav tsum muaj qhov tsos, qhov ntev, noo noo, formatdehyde emission epission txwv, thiab lwm yam uas yuav tsum muaj. Lub cev thiab tshuab cov cuab yeej yog cov tseem ceeb tshaj plaws. Qhuav MDF feem ntau suav nrog zoo li qub lub zog, Elastic Modulus, lub zog sab hauv lub zog, thiab dej nqus cov tuab loj hlob. Ntub thiab siab {- Cov av noo MDF kuj yuav tsum muaj kev ntsuam xyuas noo noo. Hais txog formaldehyde emission txwv, international nruab nrab {5 {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{ Rau cov rooj tog -} '}}}} qhov kev txwv no yog feem ntau txiav txim siab los ntawm kev sib tham thiab tus yuav. Lwm yam yuav tsum tau ua, nyob ntawm cov kev xav tau tshwj xeeb, feem ntau muaj kev txhawj xeeb cov ntsia hlau-tuav lub zog, cov khoom nqus dej, thiab seem ruaj khov.
Editor Cheng Cheng Qhov Kawg: Nruab Nrab - ntom ntom thiab lub zog, zoo rov ua haujlwm, thiab cov acoustic cov khoom lag luam. Nws yog cov khoom siv uas zoo nyiam rau cov rooj tog, cov ntaub ntawv zoo nkauj, cov twj paj nruag hauv TV, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag, thiab cov twj paj nruag rau ib qho khoom muag tseem ceeb ntawm cov khoom siv dag zog. Cov neeg tau txais kev qhia kom xaiv MDF cov khoom lag luam raws lawv cov kev siv thiab ib puag ncig kom ua kom zoo lawv lifespan thiab paub meej.
