Medium Density Fiberboard (MDF) yog ib hom khoom siv ntoo ua los ntawm me me - txoj kab uas hla, txiav thiab ua cov khoom seem, thiab tsis yog - ntoo cog fiber ntau raw cov ntaub ntawv. Cov txheej txheem suav nrog kev hlais, ua noj, sib cais fiber ntau, ziab, thiab tom qab ntawd siv urea -formaldehyde resin lossis lwm cov nplaum uas tsim nyog, ua raws li kub nias. Nws qhov ceev yog feem ntau nyob rau hauv thaj tsam ntawm 500-880 kg / cm³, thiab nws thickness feem ntau yog 2-30 hli.
MDF tau tsim nyob rau hauv nruab nrab-1960s thiab tau ntsib kev loj hlob sai txij thaum ntawd los. Qhov no yog vim nws zoo heev lub cev thiab txhua yam khoom, cov khoom zoo nkauj, thiab kev ua haujlwm.
Muaj pes tsawg leeg: Ntoo lossis tsob ntoo fibers uas tsis yog ntoo
Qhov ceev: 0.5-0.88 g / cm³
Txoj kev tsim khoom: Ntoo los yog tsob ntoo fibers yog mechanically cais thiab tshuaj kho, tov nrog nplaum thiab waterproofing agents, thiab ces molded nyob rau hauv kub thiab siab.
