Txhawm rau txhim kho anisotropy ntawm cov ntoo zoo li ntau li ntau tau, thiab ua kom cov plywood muaj cov yam ntxwv zoo thiab lub cev ruaj khov, feem ntau plywood yuav tsum ua raws li ob lub hauv paus ntsiab lus hauv kev teeb tsa: ib qho yog symmetry; lwm qhov yog tias cov fibers ntawm cov khaubncaws sab nraud povtseg uas nyob ib sab ntawm txiav yog sib sib tshuam. Lub hauv paus ntsiab lus ntawm kev sib xyaw ua ke xav tau tias cov veneers ntawm ob sab ntawm nruab nrab ntawm lub dav hlau ntawm symmetry ntawm cov plywood yuav tsum yog ua kom sib npaug tsis hais cov ntoo zoo li cas, cov tuab ntawm lub veneer, cov naj npawb ntawm cov txheej, cov kev taw qhia ntawm cov fiber , thiab cov ntsiab lus ya raws. Hauv cov ntoo plywood zoo tib yam, koj tuaj yeem siv cov veneers ntawm ib hom ntoo thiab tuab, lossis cov veneers ntawm hom ntoo thiab tuab; txawm li cas los xij, txhua ob txheej txheej ntawm cov ntoo loj ntawm cov ntoo veneer uas muaj ob sab ntawm nruab nrab ntawm lub nruab nrab dav hlau ntawm cov kab hluav taws xob yuav tsum zoo ib yam nkaus hauv tuab. Cov ncej pem hauv ntej thiab nram qab tsis raug tso cai rau tib hom ntoo.
Txhawm rau ua cov qauv ntawm plywood ntsib qhov saum toj no ob lub hauv paus ntsiab lus tib lub sijhawm, nws tus naj npawb ntawm cov khaubncaws sab nraud povtseg yuav tsum yog khib. Yog li no, plywood feem ntau yog ua los ntawm peb txheej, tsib txheej, xya txheej thiab lwm txheej khib. Cov npe ntawm cov khaubncaws sab nraud povtseg ntawm cov plywood yog: cov npoo ntawm qhov chaw hu ua qhov chaw saum npoo, sab hauv veneer yog hu ua pawg thawj coj; lub rooj tsavxwm sab saum toj yog hu ua pawg thawj coj saib, thiab pawg sab qaum yog hu ua pawg thawj coj saib; hauv pawg thawj coj saib, fiber kev taw qhia yog mus tib seem rau saum npoo. Nws yog hu ua ntev pawg thawj coj saib lossis nruab nrab board. Thaum tsim cov kab noj hniav ntawm lub rooj zaum, cov ntsej muag ntsej muag thiab phaj sab nraud yuav tsum tig sab nraud sab nraud.
