Cov Lus Qhia Kawm Tau Los ntawm Kev Siv thiab Kev Txhim Kho ntawm Plywood

Los ntawm ntau xyoo ntawm kev tsim thiab kev xyaum, kev lag luam plywood tau sau ntau yam kev paub. Qhov kev paub no tsis yog tsuas yog siv rau hauv iteration ntawm cov txheej txheem thiab thev naus laus zis tab sis kuj qhia txog kev nkag siab zoo ntawm cov khoom siv, kev xav tau ntawm kev lag luam, thiab kev txhim kho kom ruaj khov. Synthesizing thiab siv qhov kev paub no tuaj yeem muab kev txhawb nqa zoo rau kev txhim kho kev lag luam thiab siab - daim ntawv thov zoo.
Ib zaj lus qhia tseem ceeb yog nyob rau hauv kev tswj xyuas kev tsim qauv. Lub ntsiab kom zoo dua ntawm plywood stems los ntawm nws symmetrical qauv, qhov twg ib tug khib tus naj npawb ntawm veneers yog laminated nrog lawv fibers oriented perpendicularly rau ib leeg. Qhov kev tsim no zoo tiv thaiv qhov kev ntxhov siab deformation los ntawm anisotropy ntawm ntoo. Kev xyaum qhia tau hais tias kev xaiv ntawm tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab qhov sib txuam ntawm veneer thickness yuav tsum tau ua ke nrog cov kev npaj siv thiab cov yam ntxwv ntawm tsob ntoo; txwv tsis pub, teeb meem xws li warping thiab kev sib raug zoo tsis zoo yuav tshwm sim. Ntau xyoo ntawm kev paub ntau lawm qhia tau hais tias nruj symmetry nyob rau hauv veneer kev npaj thiab fiber ntau cov kev taw qhia tswj yog ib qho tseem ceeb prerequisites los xyuas kom meej qhov seem stability thiab mechanical kev ua tau zoo.
Lwm zaj lus qhia hais txog qhov tseem ceeb ntawm kev sib koom tes raw khoom thiab cov txheej txheem. High-Kev tsim cov plywood zoo yuav tsum tau kaw- kev tswj lub voj voog hauv cov khoom xws li kev txheeb xyuas cov khoom siv raw, kev tswj cov dej noo thaum lub sij hawm ziab, thiab kev npaj veneer raug. Kev paub dhau los ua pov thawj tias kev ruaj khov ntawm cov dej noo ntawm cov ntaub ntawv raw hauv qhov tsim nyog thiab kho cov kev txiav tawm los yog slicing tsis tau rau ntau hom ntoo tuaj yeem txhim kho veneer flatness thiab kev sib txuas zoo. Kev xaiv ntawm cov nplaum thiab qhov sib xws ntawm daim ntawv thov kuj yuav tsum tau ua kom zoo sib xws nrog kub nias kub, siab, thiab lub sij hawm kom tsis txhob delamination los yog ntau tshaj formaldehyde tso tawm vim cov txheej txheem deviations.
Ib zaj lus qhia thib peb yog los ntawm segmentation ntawm daim ntawv thov scenarios thiab lub hom phiaj kev ua tau zoo. Cov teb sib txawv muaj ntau yam kev xav tau rau plywood lub zog, dej tsis kam, nto zoo, thiab qib kev tiv thaiv ib puag ncig. Cov kev paub dhau los tau hais meej tias daim ntawv thov scenario simulation thiab kev kuaj xyuas kev ua tau zoo yuav tsum tau ua thaum lub sijhawm txhim kho cov khoom tsim los tsim cov kev daws teeb meem tshwj xeeb rau lub tsev formwork, rooj tog tsim khoom, ntim khoom, thiab kev thauj mus los. Piv txwv li, dej - resistant phenolic plywood yog nyiam rau sab nraum zoov engineering, thaum tsawg-formaldehyde ib puag ncig tus phooj ywg cov khoom tau txais kev pom zoo rau kev kho kom zoo nkauj sab hauv, ua tiav qhov zoo tshaj plaws sib npaug ntawm kev ua tau zoo thiab tus nqi.
Ib zaj lus qhia thib plaub qhia txog qhov tseem ceeb ntawm kev tswj kom zoo thiab kev ua qauv zoo. Ntev- lub sijhawm xyaum qhia tau hais tias tsim kom muaj cov txheej txheem kev tshuaj ntsuam xyuas thiab cov khoom lag luam tiav, suav nrog cov cim qhia xws li kev sib koom ua ke lub zog, formaldehyde tso tawm, qhov sib txawv ntawm qhov sib txawv, thiab cov tsos mob tsis zoo, tuaj yeem tsis tsuas yog txhim kho cov khoom sib xws tab sis kuj txhim kho kev lag luam kev ntseeg siab. Kev sib sau ntawm kev lag luam kev paub dhau los tau txhawb nqa kev ua kom zoo dua qub thiab ua raws li cov qauv tsim nyog, muab lub hauv paus rau kev tsim khoom thiab kev siv. Tsis tas li ntawd, kev paub txog kev siv cov peev txheej zoo thiab kev tsim ntsuab ntsuab tau txais kev saib xyuas ntxiv. Los ntawm kev sib koom ua ke me me -inch thiab ceev- ntoo loj hlob, thiab txhawb formaldehyde-dawb adhesives thiab lub zog- txuag kub- xovxwm tshuab, kev lag luam plywood tau txo nws cov ecological hneev taw thaum tswj kev ua haujlwm. Qhov no yog ob qho tib si los ntawm kev ua lag luam siab thiab kev paub txog kev hloov pauv rau kev lag luam.
Hauv cov ntsiab lus, kev txhim kho ntawm kev lag luam plywood nthuav tawm qhov kev sib txuas ntawm cov qauv kev ua kom zoo, kev sib koom ua ke, kev siv segmentation, kev tswj kom zoo, thiab kev loj hlob ntsuab, muab cov lus qhia tseem ceeb rau kev lag luam kom muaj kev vam meej hauv kev tsim kho tshiab thiab kev lag luam kev sib tw.
