Txhawm rau txo cov khoom anisotropic ntawm cov ntoo ntuj thiab kom cov qauv zoo uas yuav tsum tau ua raws li nyob rau hauv nws cov qauv: kev sib xws ntawm Veneer fibers ntawm cov khaubncaws sab nraud povtseg. Lub hauv paus ntsiab lus ntawm cov kev sib dhos uas yuav tsum tau hais tias cov Veneers ntawm ob tog ntawm cov plymethness, tooj ntawm txheej, fiber ntau taw kev taw qhia, lossis cov ntsiab lus noo noo. Ib daim ntawv plywood tuaj yeem siv cov veneers ntawm ib hom tsiaj thiab cov tuab tuab, lossis veneers ntawm cov hom sib txawv thiab cov thickinges; Txawm li cas los xij, muaj ob qho txheej txheem sib piv ntawm ob sab ntawm cov dav hlau symmetrical Central yuav tsum muaj tib hom thiab tuab. Lub ntsej muag thiab rov qab veneers tuaj yeem yog hom sib txawv.
Rau cov plywood qauv los ua ib txhij sib ntsib ob lub ntsiab cai, nws tus naj npawb ntawm cov khaubncaws sab nraud povtseg yuav tsum khib. Yog li ntawd, plywood feem ntau yog ua nrog peb, tsib, xya, lossis lwm yam khib {{}}}} cov khaubncaws sab nraud. Cov npe ntawm txheej hauv plywood muaj raws li hauv qab no: tus veneer sab saum toj yog hu ua lub ntsej muag veneer, thiab sab hauv veneer hu ua tus tseem veneer; Cov Veneer pem hauv ntej yog hu ua lub ntsej muag Veneer, thiab lub ntsej muag sab nraub qaum yog hu ua sab nraud veneer; Ntawm cov neeg ua yeeb yam tseem ceeb, cov neeg nrog cov fibers sib piv rau lub ntsej muag veneer tau hu ua ntev cov veneers lossis nruab nrab ntawm cov neeg sib tw nruab nrab. Thaum sib dhos cov kab noj hniav Board dawb, lub ntsej muag Veneer thiab rov qab Veneer thiab rov qab Veneer thiab rov qab Veneer thiab rov qab nce sab sab nraud ntsib sab nraud.
