Kev faib tawm ntawm Fiberboard

Feem ntau muab faib ua ob pawg ntawm cov uas tsis muaj qhov-khaus thiab ntsuas raws qhov ceev cov khoom. Cov khoom tsis-compressed yog mos fiberboard nrog qhov ntom tsawg dua 0.4 g / cm3; compression cov khoom xws li cov khoom nruab nrab ntawm fiberboard (tseem hu ua semi-rigid fiberboard nrog qhov ntom ntawm 0.4 rau 0.8g / cm3) thiab cov tawv fiberboard (nrog rau qhov ntom ntau dua 0.8g / Cm3). Raws li cov txheej txheem ua ntu zus, nws tuaj yeem faib ua cov fiberboard ntub dej, qhuav fiberboard, thiab cov tsom iav fiberboard. Raws li cov txheej txheem tom qab ua tiav, nws tuaj yeem faib ua cov fiberboard zoo tib yam thiab roj-kho kho fiberboard. Cov ntoo fiberboard yog qhov hnyav hauv qhov hnyav thiab muaj qhov porosity loj. Nws muaj lub rwb thaiv cua kub zoo thiab lub suab nqus tau. Tom qab kev kho mob tshwj xeeb, lub teeb fiberboard nrog ntau lub qhov hws tuaj yeem tau txais, uas muaj cov adsorption kev ua tau zoo thiab tuaj yeem siv rau kev lim cua. Cov koob fiberboard nruab nrab muaj cov qauv tsis sib xws, cov khoom nruab nrab ntawm lub cev thiab lub zog, thiab ua haujlwm zoo. Cov khoom lag luam muaj ntau yam tuab thiab muaj ntau yam siv, xws li cov rooj tog khoom siv thiab cov khoom siv TV hauv tsev. Cov khoom siv fiberboard nyuaj muaj qhov tuab me me, ntawm 3 txog 8 hli. Lub zog siab, 3 txog 4 hli tuab tawv fiberboard yuav siv tsis tau 9 txog 12 hli sawn cov ntawv ntoo. Feem ntau siv hauv cov tsev, nkoj, tsheb, thiab lwm yam.
