Peb kuj tau ua cov rooj tog ua los ntawm lwm cov ntaub ntawv ntxiv rau cov cav ntoo, suav nrog plywood thiab ntiv tes boards, tab sis tam sim no peb tsuas yog ua cov plywood siv cov ntaub ntawv hauv qab no: E0, E1, thiab E2 txhua tus xa mus rau ib puag ncig cov qauv uas txwv tsis pub muaj formaldehyde tso tawm.E2 (≤ 5.0mg / L), E1 (≤1.5mg / L), E0 (≤0.5mg / L)
E1 yog qhov yuav tsum tau ua hauv kev lag luam plywood kom tau raws li kev ua neej nyob.Nrog kev xav tau ntau ntxiv rau cov khoom,
Cov khoom ntoo ntau txheej plywood tau nce lawv cov kev tiv thaiv ib puag ncig mus rau E0.
Yuav ua li cas paub qhov zoo ntawm plywood, nws tuaj yeem paub qhov txawv ntawm cov ntsiab lus hauv qab no:
Ua ntej, lub zog sib txuas yog qhov zoo;Txhua hom board nplaum quab yuam zoo dua, uas txhais tau hais tias lub nplaum nplaum yog qhov yuav tsum tau ua ua ntej.Ua ntej, saib seb puas muaj cov xwm txheej pom tseeb nyob ib puag ncig thiab seb puas muaj npuas ntawm qhov chaw.Secondly, los ntawm manually thawb thiab nias lub clamp, koj puas hnov tej suab nrov.Tau kawg, yog tias muaj suab nrov, nws yuav tsis tas yuav yog vim cov nplaum tsis zoo.Tej zaum nws yuav yog vim lub hollow core los yog cov khoom siv tsis zoo siv rau lub rooj tsavxwm, tab sis nws tag nrho qhia tias qhov zoo tsis zoo.
Qhov thib ob, qhov flatness yog qhov zoo;Los ntawm qhov no, nws tuaj yeem pom tias cov khoom siv sab hauv ntawm lub rooj tsavxwm yog siv.Thaum peb tab tom saib ntawm lub rooj tsavxwm, peb kov nws nrog peb txhais tes kom hnov yog tias muaj qhov tsis sib xws.Yog tias muaj, nws qhia tau hais tias ob lub ntsiab lus: qhov saum npoo tsis zoo sanded, los yog lub core board yog ua los ntawm cov ntaub ntawv tsis zoo, uas yog fragmented.
Thirdly, Lub thickness ntawm lub rooj tsavxwm, qhov yooj yim dua nws pom.Piv txwv li, 18cm multi-layer plywood yog tsim los ntawm nias 11 txheej ntawm core board.Yog hais tias txhua txheej yog ua los ntawm tag nrho cov khoom, cov khaubncaws sab nraud povtseg yog heev meej thiab yuav tsis muaj tshwm sim ntawm overlapping txheej.Yog tias cov ntaub ntawv tsis siv zoo thiab muaj ntau cov ntaub ntawv crushed, vim lub siab, cov khaubncaws sab nraud povtseg yuav sib tshooj thiab tsim qhov tsis sib xws.
Plaub, lub rooj tsavxwm zoo yeej tsis deform;Qhov degree ntawm deformation yog feem ntau cuam tshuam nrog lub cev ntawm cov ntoo nws tus kheej, nws cov ntsiab lus noo noo, thiab kev nyab xeeb.Qhov peb tuaj yeem tswj tau yog cov dej noo.Peb kuj tuaj yeem xaiv ntoo nrog tsawg deformation.
Thib tsib, seb lub thickness yog nyob rau hauv tus txheej txheem ntau yam;Feem ntau hais lus, lub thickness ntawm cov boards zoo yog nyob rau hauv ntau yam ntawm lub teb chaws tus qauv.
Lub pem hauv ntej ntawm lub rooj tsavxwm ntiv tes yog tib yam li ntawm cov plywood ntau txheej.Finger board yog ib lub rooj tsavxwm uas ua los ntawm kev sib txuas cov khoom pov tseg tom qab ua cov ntoo nyoos, thiab cov txheej txheem ntau txheej yog ib lub rooj tsavxwm uas txiav cov ntoo thawj zaug rau hauv nyias daim thiab muab lawv ua ke.Tus nqi ntawm ob yog qhov zoo sib xws, tab sis vim tsis muaj txheej txheej ntawm cov ntiv tes ntiv tes, nws yooj yim dua rau deformation piv rau ntau txheej plywood.
Qhov siv tau ntawm cov ntiv tes sib koom ua ke tsis yog qhov dav li ntawm ntau txheej daim hlau.Piv txwv li, yog tias qee qhov elongated Cheebtsam siv nrog cov ntiv tes sib koom ua ke, lawv lub peev xwm thauj khoom tsis zoo li cov txheej plywood ntau, thiab lawv yuav ua rau tawg nyob rau hauv qee qhov kev quab yuam sab nraud.Finger boards feem ntau yog siv los ua cov rooj zaum loj thiab cov txee.Thiab cov plywood ntau txheej no tuaj yeem ua tau, yog li peb tsis tshua siv cov ntiv tes sib koom ua ke tam sim no.
