Plywood yog hom ntoo ntawm cov txiv neej-ua ntoo uas yog thim rov los ntawm tev.
Plywood yog tsim los ntawm kev txiav mus rau hauv thaj chaw loj hauv qhov chaw hauv kev coj ntawm txhua xyoo. Tom qab ziab thiab ua kom tiav, nws tsim tau raws li tus qauv ntawm txoj kab ntsug mahogany ntsug kev teeb tsa ntawm cov nyob ib sab.
Tus naj npawb ntawm cov tub ntxhais hluas feem ntau yog tus naj npawb khib ntawm cov khaubncaws sab nraud povtseg, feem ntau peb mus txog kaum peb txheej, thiab cov khaubncaws sab nraud ntawm cov khaubncaws sab nraud feem ntau yog peb txheej, tsib txheej, cuaj txheej, thiab 13 txheej (kev lag luam muag khoom feem ntau hu ua peb txheej ntoo, tsib plywood, cuaj plywood, Kaum peb centimeters). Lub xub ntiag ntawm sab nraud ntawm txheej sab nraud yog hu ua lub rooj vaj huam sib luag pem hauv ntej, sab nraub qaum yog hu ua vaj huam sib luag tom qab, thiab txheej sab hauv hu ua pawg thawj coj.
Hom 1 plywood muaj qhov zoo ntawm huab cua tsis kam, rhaub dej tsis kam, siab ntev, siab kub, thiab chav tiv taus.
Cov 2 hom plywood yog cov dej plywood, uas tuaj yeem tsau rau hauv cov dej txias thiab dej kub hauv lub sijhawm luv.
Hom 3 plywood yog dej plywood, uas tuaj yeem muab tso rau hauv dej txias rau lub sijhawm luv luv, uas yog haum rau qhov kub hauv tsev. Rooj tog thiab siv cov hom phiaj dav dav;
Hom 4 plywood yog noo plywood-resistant, uas feem ntau siv nyob hauv tsev. Cov ntoo plywood feem ntau suav nrog birch, eucalyptus, thiab poplar.
Plywood yog tsuas yog siv nyob rau sab nraum zoov tej yam kev mob, xws li kev ua vaj tsev sab nrauv kho kom zoo nkauj thiab pob zeb formwork. Hauv kev kho kom zoo nkauj, nws yog feem ntau yog siv hauv cov vov tsev, daim tiab phab ntsa, thiab cov kab hauv pem teb.
Cov qauv muaj pes tsawg leeg ntawm plywood
Txhawm rau txhawm rau txhim kho lub anisotropy ntawm ntuj ntoo kom ntau li ntau tau, plywood muaj cov yam ntxwv tsis sib xws thiab cov duab kom ruaj khov. Feem ntau, plywood yuav tsum ua raws li ob txoj hauv kev nyob hauv tus qauv: ib qho yog symmetrical; lwm qhov yog nyob ib sab ib leeg-tswj kho qhov muag cov hluav taws xob yog txiav kom sib.
Lub hauv paus ntsiab lus ntawm kev ua kom sib npaug yog plywood xav tau ntawm ob sab ntawm nruab nrab lub dav hlau ntawm symmetry ntawm cov plywood, tsis hais cov ntoo zoo li cas, tuab ntawm cov plywood, cov naj npawb ntawm cov khaubncaws sab nraud povtseg, kev taw qhia ntawm lub fiber, thiab cov av noo cov ntsiab lus yuav tsum yog symmetrical rau txhua lwm yam.
Hauv cov ntoo plywood ib leeg, ib leeg ntoo thiab lub veneers ntawm cov tuab tuaj yeem siv, lossis cov veneers ntawm cov ntoo sib txawv thiab tuab tau siv tau; txawm li cas los xij, txhua txheej txheej ob txheej ntawm cov ntoo ntawm cov ntoo thiab cov tuab tuab ntawm ob sab ntawm lub tshav puam nruab nrab zoo ib yam.
Txhawm rau ua tus qauv ntawm cov plywood ntsib qhov saum toj no ob lub hauv paus ntsiab lus, tus naj npawb ntawm cov khaubncaws sab nraud povtseg yuav tsum yog khib.
Yog li no, plywood feem ntau muab faib ua peb txheej, tsib txheej, xya txheej thiab lwm txheej tsis txawv.
Lub npe ntawm cov txheej txheej plywood yog: txheej txheem veneer yog hu ua rooj, sab hauv veneer yog hu ua pawg thawj coj; lub vaj huam sib luag pem hauv ntej yog hu ua vaj huam sib luag, thiab vaj huam sib luag tom qab yog hu ua vaj huam sib luag tom qab; hauv pawg thawj coj saib, kev taw qhia fiber ntau yog mus tib seem rau vaj huam sib luag.
Nws yog hu ua pawg thawj coj ntev lossis nruab nrab-board.
Qhov zoo ntawm plywood
Qhov zoo ntawm plywood yog muaj zog bearing peev xwm, tsis yooj yim rau deform thiab khoov, tsis yooj yim kom tawg, thiab nthuav me me. Multilayer board muaj lub peev xwm zoo los hloov rau qhov kub thiab txias thiab av noo. Cov txheej txheej saum npoo ntawm multilayer board yog ntuj ntoo. Cov noob ntoo ua si tau nyob ze rau cov qauv thiab hom loj heev. Qhov zoo ntawm cov thawv ntau txheej yog ib qho yooj yim rau kev thawb. Piv nrog lub cav ntoo, cov thooj ntau txheej ua kom tsis txhob muaj qee qhov tsis zoo ntawm cov ntoo zoo, xws li kev plam, dav, deformation, thiab tsis zoo nyem tsis kam.
Ntau txheej laug cam kuj muaj qhov zoo zoo dua li ntuj ntoo hauv tus nqi. Txij li cov txiag ntoo ua ntau txheej rov tshawb dua thiab rov txhim kho lub cav, lawv tau txuag nyiaj ntau dua li cov khoom lag luam ntoo khoom kim.
Qhov tsis zoo ntawm cov pawg multilayer
Lub Rooj Tswjhwm Saib ntau txheej yog ua los ntawm cov khoom siv ntoo tshwj xeeb board los ntawm kev kub thiab kub siab nias hauv xovxwm kub nrog lub nplaum. Yog li ntawd, hais txog kev tiv thaiv ib puag ncig, yuav muaj qee qhov kev tso tawm formaldehyde. Tab sis nws yog qhov ze rau ntuj ntoo thiab kuj yog qhov feem ntau ib puag ncig tus phooj ywg ntoo.
Kev txheeb xyuas qhov zoo lossis tsis zoo plywood
Ua ntej, saib ntawm lub tiaj tiaj ntawm lub vaj huam sib luag. Txij ntawm no, peb tuaj yeem pom cov khoom lag luam sab hauv. Thaum peb saib lub rooj tsavxwm, peb tuaj yeem kov nws nrog peb txhais tes thiab xav tias puas muaj qhov tsis sib xws. Yog tias muaj, nws txhais tau hais tias cov xuab zeb saum npoo tsis zoo.
Tog twg los nws txhais tau hais tias cov khoom siv hauv board board tsis zoo thiab cov khoom siv kuj sib tawg. Hauv ntej, nws tsis pom zoo kom yuav qhov tsis xwm yeem.
Thib ob, soj ntsuam qhov kev nkag siab ntawm qhov hierarchy ntawm lub multilayer board. Lub thicker lub Rooj Tswjhwm Saib, qhov yooj yim dua yog kom pom kev teeb tsa ntawm cov pawg ntau txheej. Yog tias txhua txheej tau ua los ntawm cov khoom siv monolithic, cov khaubncaws sab nraud povtseg yuav pom tseeb heev thiab yuav tsis muaj qhov pom tshwm sim ntawm txheej nruab nrab. Yog hais tias cov khoom tsis zoo, muaj ntau ntawm kev sib tw.
Vim los ntawm qhov tshwm sim ntawm lub siab, qib yuav ua zuj zus tom qab sib txhuam.
