Qhov txawv ntawm MDF thiab Plywood
Jan 03, 2023
MDF yog nruab nrab ntom fiberboard thiab playwood yog plywood.
1. MDF yog nruab nrab ntom fiberboard
2. Medium density fiberboard yog ib hom khoom siv board ua los ntawm cov ntoo fiber ntau lossis lwm cov nroj tsuag fibers, uas yog crushed, fiber ntau sib cais, qhuav, siv nrog urea formaldehyde resin los yog lwm yam ntaub ntawv nplaum, thiab ces kub nias. Nws qhov ceev yog feem ntau nyob rau hauv thaj tsam ntawm 500-880kg / m3, thiab nws thickness feem ntau yog 5-30 hli.
3. Medium density fiberboard (MDF) yog ib yam khoom tsim nyob rau hauv nruab nrab -1960s, thiab nws cov zis tau tsim sai heev nyob rau hauv xyoo tas los no. Yog vim li cas yog hais tias nws muaj zoo heev lub cev thiab mechanical zog, zoo nkauj zog thiab ua cov khoom. MDF (Medium Density Fiberboard) tseem hu ua particle board thiab fiberboard. Nws yog ua los ntawm cov ntoo, cov ntawv siv dua tshiab, xyoob, carbon fiber thiab straw tom qab ua haujlwm ntau. Nws yog superior rau tej yam ntuj tso ntoo nyob rau hauv stability, siab kub kuj thiab lwm yam ntsuas, thiab nws cov nqi yog tsawg. Tsis tas li ntawd, kev tsim cov khoom siv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom tuaj yeem ua tiav kev siv cov khoom pov tseg thiab cov ntoo nrawm nrawm uas tsim tawm hauv kev txiav, txiav ntoo thiab ua cov cav ntoo, uas yog qhov tseem ceeb rau kev tiv thaiv hav zoov hauv Suav teb.. Plywood yog peb txheej lossis multilayer board zoo li cov khoom ua los ntawm cov ntoo uas tau tev rau hauv veneer los yog hlais rau hauv cov ntoo nyias los ntawm kev npaj ntoo, thiab tom qab ntawd glued nrog cov nplaum. Feem ntau, khib cov khaubncaws sab nraud povtseg ntawm veneer yog siv, thiab cov lus qhia fiber ntau ntawm cov khaubncaws sab nraud povtseg ntawm veneer yog perpendicular rau ib leeg.
