Tus qauv ntawm ntug ntoo-glued ntoo tsuas yog muaj veneer, nplaum thiab cov khaubncaws sab nraud. Veneer yog chav tsev yooj yim ntawm plywood, feem ntau tau los ntawm peeling lossis slicing cav, nrog ib thickness ntawm {}}. 3 hli thiab 4 hli. Veneer tuaj yeem faib ua ntsej muag, rov qab thiab cov tub ntxhais. Lub ntsej muag yog cov neeg sab nraud sab nraud, uas feem ntau yog ua los ntawm cov ntoo zoo dua los xyuas kom muaj qhov zoo nkauj; Sab nraub qaum yog cov veneer veneer, uas muaj qhov yuav tsum tau ua tau zoo dua; Cov tub ntxhais siv cov ntoo pheej yig dua lossis cov veneer tsawg.
Cov nplaum nplaum xws li urea-formaldehyde cob (UF), phenol-formatdehyde cob (PF) thiab Melamine Resin (MF). Urea-formaldehyde cob muaj tus nqi qis thiab haum rau hauv tsev siv hauv tsev, tab sis muaj dej tsis zoo thiab tiv thaiv cua sov; Phenol-formaldehyde cob muaj cov dej tsis kam thiab kub ua hauj lwm thiab yog qhov tsim nyog rau kev siv sab nraum zoov, tab sis muaj tus nqi ntau; Melamine Resin muaj cov dej tsis kam thiab kub ua hauj thiab yog qhov tsim nyog rau siv nyob rau hauv cov chaw noo.
Plywood feem ntau muaj tus lej khib ntawm txheej, xws li peb, tsib, thiab lwm yam Cov qauv no pab tswj cov kev ua kom zoo nkauj thiab txo qhov tau ua warping. Txhawm rau txhawm rau txhim kho qhov ruaj khov ntawm plywood, cov pas dej feem ntau yog staggered, uas yog, ntoo ntoo kab ke ntawm cov khaubncaws sab nraud povtseg. Piv txwv li, cov ntoo qoob loo ntawm thawj txheej ntawm veneer yog ntev, thib ob txheej yog transverse, thib peb txheej rov qab los ntev, thiab lwm yam.
Cov xwm txheej tshwj xeeb ntawm ntug-glued ntoo muaj xws li rooj tog, kev tsim kho, ntim thiab lwm thaj teb. Piv txwv li, peb-txheej pawg phab ntsa feem ntau siv nyob rau hauv cov rooj tog thiab kev tsim kho vim lawv txoj kev tsis zoo heev thiab cuam tshuam; Tsib-txheej pawg ntseeg muaj cov qauv kev cog lus, muaj kev nyuaj siab, thiab feem ntau siv tau los ua cov khoom rooj tog, flooring thiab ntim thawv; Xya-txheej pawg pab pawg muaj kev ruaj khov zoo thiab sib npaug, thiab lub zog zoo thiab hardness.
