Ib qho ntawm cov khoom siv ntau tshaj plaws yog edged board. Nws yog tsim los ntawm sawing tawm ntawm ib lub cav. Nyob rau hauv cov ntaub ntawv no, cov npoo yog txiav nyob rau hauv xws li ib txoj kev uas tsis muaj bark (wane) rau lawv. Qee qhov xwm txheej, qhov tsis xws luag muaj nyob rau hauv me me. Feem ntau, nws tus nqi yog tswj los ntawm GOST cov qauv. Hom ntoo no tau siv dav hauv kev tsim kho.
Nyob rau hauv Russia, edged boards yog muag nyob rau hauv ntau qhov ntau thiab tsawg tus qauv. Yog li, cov khoom yog tsim nrog ib tug tuab ntawm 22, 25, 30, 40, 50, 100 los yog 150 mm, ib tug dav ntawm 100, 150 thiab 200 mm, thiab qhov ntev yuav ua tau 3, 4 los yog ntau tshaj kev xaiv - 6 meters. Thaum ua haujlwm, qhov zoo tshaj plaws qhov sib txawv ntawm qhov ntev yog xaiv, uas tso cai rau kev siv tau zoo tshaj plaws ntawm cov ntoo ntoo, thaum ua kom ntseeg tau qhov tsim nyog ntawm cov qauv. Nws tseem tsim nyog sau cia tias nws tuaj yeem tsim cov laug cam ntawm tus kheej xaj yog tias xav tau qee qhov loj.
Ntxiv rau qhov sib txawv ntawm qhov loj me, edged boards kuj yog cov yam ntxwv ntawm cov ntoo, kev huv huv, thiab cov txheej txheem ua tiav. Nyob rau hauv tag nrho cov noCov ntsuas ntsuas ntsuas qib ntawm cov ntoo. Thiab nws yog qhov kev ntsuas no uas feem ntau tsim tus nqi ntawm cov khoom thiab, tau kawg, qhov zoo.
Edged board muab faib ua tsib qib, uas yog: xaiv (qhov zoo tshaj) thiab qib 1, 2, 3 thiab 4. Qhov taw qhia yog muab rau lumber raws li GOST 6564-84.
Hauv kev tsim kho, cov laug cam ua los ntawm ntoo thuv, spruce, larch, birch, thiab lwm yam. Txhua yam ntawm cov ntoo no muaj nws tus kheej tshwj xeeb pros thiab cons. Qhov kev xaiv feem ntau nyob ntawm thaj tsam ntawm cov ntoo, kev ua haujlwm, kev tsim kho.
Nyob rau hauv ntau txoj kev, qhov zoo ntawm edged boards yog txiav txim los ntawm cov xwm txheej ntawm lawv cia. Feem ntau lawv yog stacked. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los xyuas kom meej huab cua zoo, tshwj xeeb tshaj yog, nws cov dej ntws hauv cov ntoo nteg. Ua tsaug rau qhov no, ntoo qhuav thiab cov laug cam tsis rot.
Ntxiv rau, txhawm rau khaws cia qhov zoo li qub thiab zoo, lub rooj tsav xwm edged tau kho nrog cov tshuaj tua kab mob tshwj xeeb uas tiv thaiv kev lwj, kab mob fungal, thiab kab tsuag ntoo. Cov neeg tsim khoom feem ntau ua tiav cov txheej txheem no nyob rau hauv qhov siab, vim tias qhov kev nkag mus tob dua ntawm cov khoom siv hauv cov khoom tau ua kom ntseeg tau. Uas, raws li, ua rau kev tiv thaiv zoo ntawm cov khoom. Ib yam khoom kho tau zoo li no yuav kav ntev thiab ntseeg tau.
Edged board yog dav siv hauv kev tsim kho ob qho tib si rau qee yam haujlwm thiab tsim cov qauv tshwj xeeb,rau ob qho tib si sab hauv thiab sab nrauv tiav. Feem ntau, edged boards yog siv rau hauv kev tsim kho ntawm cov plag tsev, nrog rau hauv kev tsim cov ru tsev, tsim cov ceilings, thav ntawv rau partitions, ntxhib flooring thiab ntau ntxiv. Lumber pom nws siv hauv kev tsim cov rooj tog. Cov pawg qis qis raug xaiv rau kev ua tiav ntxhib, thiab cov ntoo zoo dua yog siv rau cov khoom tseem ceeb hauv tsev.
