1. Ua ntej tshaj plaws, cov khoom siv los ua ob qhov sib txawv.Cov qub yog ua los ntawm cov ntoo veneers ntawm tib lub thickness, sib txuas nrog cov kua nplaum, thiab tom qab ntawd kho nrog kub thiab siab siab;thaum lub tom kawg muaj ib tug thicker nruab nrab ib feem.Lub rooj ntoo ntoo yog ua los ntawm cov veneer nyias nyias ntawm ob sab.Lub rooj tsavxwm ntoo thiab veneer yog sib koom ua ke nrog cov kua nplaum thiab tom qab ntawd ua tiav los ntawm qhov kub thiab txias.
2. Plywood muaj cov qauv ruaj khov, lub zog siab, thiab tsis yooj yim rau deform, yog li nws tuaj yeem tsim cov duab tsawg dua, thiab cov kua nplaum ntau ntxiv thaum lub sijhawm tsim khoom, yog li yog tias nws siv tsis raug, nws yuav ua rau muaj kuab paug ntau dua rau cov khoom siv. ib puag ncig;thiab Qhov saum npoo ntawm lub rooj tsavxwm ntoo yog tiaj tus thiab du thiab tuaj yeem deformed me ntsis.
3. Raws li ib txwm muaj, tus nqi ntawm plywood yog qis dua li ntawm cov ntoo ua haujlwm.
Plywood yog ib txheej peb-txheej los yog ntau-txheej phaj cov khoom ua los ntawm cov ntu ntoo uas yog rotary txiav rau hauv veneers los yog npaj rau hauv cov ntoo nyias, thiab tom qab ntawd glued ua ke nrog cov nplaum.Feem ntau siv cov khib nyiab ntawm cov veneers, thiab cov khaubncaws sab nraud povtseg ntawm veneers raug cais.Cov lus qhia fiber ntau yog glued vertically rau ib leeg.Plywood yog ib qho ntawm cov khoom siv feem ntau siv rau cov rooj tog zaum thiab yog ib hom khoom siv board.Ib pawg ntawm veneers feem ntau yog tsim los ntawm gluing nyob ib sab cov khaubncaws sab nraud povtseg rau ib leeg nyob rau hauv cov kev taw qhia ntawm ntoo grain.Feem ntau cov vaj huam sib luag saum npoo thiab sab hauv txheej panels yog symmetrically teem rau ob sab ntawm lub hauv paus txheej los yog cov tub ntxhais.Lub slab yog ua los ntawm cov nplaum nplaum veneers criss-hla nyob rau hauv cov kev taw qhia ntawm ntoo grain, thiab yog nias nrog los yog tsis muaj cua sov.
