1. Plywood tau muab faib ua peb lossis ntau txheej ntawm cov ntoo nyias nyias thiab nplaum. Feem ntau ntawm cov ntoo nyias ua tam sim no yog spun nyias ntoo, uas feem ntau hu ua veneer. Feem ntau siv cov veneers uas tsis muaj lej. Cov lus qhia fiber ntau ntawm cov veneers uas nyob ib sab yog perpendicular rau ib leeg. Peb ply, tsib ply, xya ply thiab lwm yam khib tus lej plywood feem ntau yog siv. Sab nrauv veneer yog hu ua veneer, pem hauv ntej veneer hu ua vaj huam sib luag, rov qab veneer yog hu ua phaj rov qab, thiab sab hauv veneer hu ua core phaj lossis nruab nrab phaj.
2. Hom ntawm plywood vaj huam sib luag yog hom ntawm plywood. Hauv Suav teb, cov ntoo uas siv dav dav yog basswood, Fraxinus mandshurica, birch, poplar, elm, maple, xim ntoo, Huangbo, maple, nanmu, Schima superba, thiab Suav wolfberry. Cov ntoo coniferous uas nquag siv yog masson ntoo thuv, Yunnan ntoo thuv, larch, spruce, thiab lwm yam.
3. Muaj ntau txoj hauv kev rau kev faib cov plywood, uas tuaj yeem faib raws li hom ntoo, xws li ntoo plywood (birch plywood, tropical hardwood plywood, thiab lwm yam) thiab coniferous plywood;
4. Raws li lub hom phiaj, nws tuaj yeem muab faib ua cov plywood zoo tib yam thiab cov plywood tshwj xeeb. Ordinary plywood yog cov plywood haum rau ntau lub hom phiaj, thiab cov plywood tshwj xeeb yog cov plywood rau lub hom phiaj tshwj xeeb;
5. Raws li cov dej tsis kam thiab ua haujlwm ntev ntawm cov nplaum txheej, cov plywood zoo tib yam tuaj yeem muab faib ua huab cua plywood (chav kawm I plywood, nrog durability, boiling resistance lossis chav kho, tuaj yeem siv sab nraum zoov), dej-resistant plywood (chav kawm II plywood, tuaj yeem soaked hauv dej txias, lossis feem ntau soaked hauv dej kub rau ib lub sij hawm luv luv, tab sis tsis resistant rau boiling) Moisture resistant plywood (Class III plywood, uas muaj peev xwm tiv taus dej txias rau lub sij hawm luv luv thiab yog haum rau siv sab hauv tsev) thiab cov plywood tsis ya raws (chav kawm IV plywood, uas yog siv nyob rau hauv ib txwm nyob sab hauv tsev thiab muaj tej yam kev sib raug zoo zog).
6. Raws li cov qauv ntawm plywood, nws tuaj yeem muab faib ua plywood, sandwich plywood thiab composite plywood. Sandwich plywood yog plywood nrog phaj core, thiab cov plywood composite yog cov plywood nrog phaj core (los yog ib co txheej) muaj li ntawm cov ntaub ntawv uas tsis yog cov khoom ntoo los yog veneer. Ob sab ntawm lub phaj tub ntxhais feem ntau muaj tsawg kawg yog ob txheej ntawm veneers nrog ntoo grain vertically teem nrog ib leeg.
7. Raws li kev ua haujlwm saum npoo, nws tuaj yeem muab faib ua sanded plywood, scraped plywood, veneered plywood thiab pre veneered plywood. Sanded plywood yog cov plywood uas nws nto yog sanded los ntawm sander, scraped plywood yog cov plywood uas nto yog scraped los ntawm scraper, thiab veneered plywood yog cov khoom siv veneer xws li hniav veneer, ntoo grain ntawv, impregnated ntawv, yas, resin nplaum zaj duab xis los yog hlau ntawv, Lub prefabricated plywood yog cov plywood uas tau tshwj xeeb kho thaum lub sij hawm tsim khoom thiab tsis tas yuav tsum tau hloov kho thaum siv.
8. Raws li cov duab ntawm plywood, nws tuaj yeem muab faib ua dav hlau plywood thiab tsim plywood. Tsim plywood hais txog cov plywood uas tau ncaj qha nias rau hauv cov duab nkhaus hauv cov pwm raws li qhov yuav tsum tau ua ntawm cov khoom, rau cov kev xav tau tshwj xeeb, xws li phab ntsa tiv thaiv board, corrugated plywood ntawm lub qab nthab, backrest thiab nraub qaum ntawm lub rooj zaum.
9. Txoj kev tsim cov plywood feem ntau yog cov txheej txheem cua sov qhuav, uas yog, tom qab cov veneer qhuav yog coated nrog cov kua nplaum, nws tau muab tso rau hauv ib lub xovxwm kub kom glued rau hauv plywood. Cov txheej txheem tseem ceeb muaj xws li cav scribing thiab hla sawing, ntu ntoo thaum tshav kub kub kho, ntu ntu nruab nrab thiab teb txiav, veneer kom qhuav, veneer sizing, slab npaj, slab pre pressing, kub nias, thiab ib tug series ntawm tom qab kho.
Lub hom phiaj ntawm kev kho cua sov ntawm cov ntoo yog kom muag cov ntu ntoo, ua kom cov yas ntawm cov ntoo, ua kom cov ntu ntoo tom qab txiav los yog npaj, thiab txhim kho qhov zoo ntawm veneer. Cov txheej txheem ntawm ntoo ntu kev kho cua sov muaj xws li boiling, kev kho cua sov ib txhij ntawm dej thiab cua, thiab kev kho cua sov.
