Kev ziab ntoo yog ua tiav kom tshem tawm qee feem pua ntawm cov dej noo los ntawm nws. Nws yog nqa tawm nyob rau hauv thiaj li yuav ua kom ruaj khov linear qhov ntev ntawm cov khoom. Qhov no tseem ceeb heev hauv kev tsim kho thiab qee qhov chaw. Nco ntsoov tias kev ziab ntoo muaj ob txoj hauv kev: hloov cov dej noo thiab hloov cov dej noo. Thawj yog qhov txav ntawm cov dej hauv tsob ntoo, qhov thib ob yog nws cov evaporation rau hauv ib puag ncig. Txhawm rau kom tau txais cov txiaj ntsig xav tau, tib qhov kev siv ntawm cov txheej txheem yog tsim nyog. Txwv tsis pub, kev ntxhov siab sab hauv tuaj yeem tshwm sim, uas thaum kawg yuav ua rau deformation thiab tawg.
Qhov teeb meem tseem ceeb uas cov tshuab ziab khaub ncaws yuav tsum daws yog qhov nrawm nrawm ntawm cov dej ntws los ntawm cov txheej sab hauv mus rau sab nrauv. Rau dehumidification, muaj ntau yam khoom siv sib txawv. Kev txav ntawm cov dej hauv tsob ntoo yog ua raws li cov hauv qab no: av noo, kub, siab. Yuav kom meej meej, lawv muaj qhov sib txawv ntawm cov ntsiab lus sib txawv hauv cov khoom.
Kev ziab ntoo yuav tsum tau ua los ntawm kev siv cov khoom siv uas tuaj yeem muab cov haujlwm hauv qab no: txo cov kab nrib pleb thiab deformations, txo kev siv hluav taws xob thiab sijhawm ntau li ntau tau. Ib qho ntawm cov thev naus laus zis siv rau cov txheej txheem no yogziab hauv chav tshwj xeeb. Lub tshuab nqus tsev ziab ntawm cov ntoo muaj kev npaj ntawm ib pawg ntawm cov ntoo ntub dej, nws preheating, cov txheej txheem tseem ceeb ntawm kev tshem dej, nruab nrab thiab zaum kawg kev kho cua sov thiab txias.
Nyob ntawm lub hom phiaj ntxiv ntawm kev siv cov khoom siv, muaj plaub pawg ntawm kev ua ntoo: I, II, III, 0. Qhov zoo tshaj plaws yog ziab ntawm cov ntoo ntawm qeb kuv zoo. Nws yog tsim rau lumber siv nyob rau hauv lub neej yav tom ntej rau kev tsim khoom ntawm tej yam uas yuav tsum tau ua kom muaj kev khiav hauj lwm. Qeb xoom txhais tau tias tshem tawm cov dej noo mus rau theem uas tso cai rau cov khoom thauj mus los rau kev xa tawm thiab siv hauv tsev.
Kev ziab kom zoo yog txiav txim siab los ntawm ob peb yam. Ntawm lawv yog cov tseem ceeb: qhov nruab nrab noo noo cov ntsiab lus ntawm ib tsob ntoo nyob rau hauv ib pawg thiab nws deviation los ntawm ib tug tej yam lub hom phiaj tus nqi, residual kev nyuaj siab nyob rau hauv cov txheej txheem lumber, kev sib piv ntawm tus nqi ntawm noo noo nyob rau hauv ib tug boards nrog ib tug qhia tag nrho rau ib tug uniformly. folded batch. Tsis tas li ntawd, qhov sib txawv ntawm feem pua ntawm cov ntsiab lus ntawm cov kua hauv cov thickness.
Tsis tas li cov txheej txheem ziab tuaj yeem ua tiav qhov kev xav tau, nrog rau kev sib txawv, ntau yam tsis xws luag tuaj yeem tshwm sim. Lub ntsiab tseem ceeb yog: pwm, plhaub, underdrying ntawm pawg ntawm cov khoom raws li tag nrho, muaj zog warping ntawm cov laug cam, unevenly tshem tawm ntawm noo noo raws lub thickness ntawm assortment los yog lub ntim ntawm ib tug uniformly folded batch ntawm ntoo, vau,tawg. Cov laj thawj ntawm qhov tsis xws luag yog feem ntau: tsis ua raws li kev siv thev naus laus zis, kev tswj tsis zoo ntawm cov txheej txheem, cua sov tsis sib xws, kev faib tawm thiab cov cua tsis zoo, tsis zoo ntawm cov khoom siv hauv pawg, ntau dhau kev quab yuam kom qhuav., hom ntoo (qhov no, yuav tsum tau npaj ntxiv).

Kev siv tshuab ntoo thiab tsim cov khoom ntoo
Ntoo yog ib yam khoom txawv txawv thiab tshwj xeeb tshaj yog muaj txiaj ntsig. Rau tag nrho nws cov kev paub, nws muaj cov txheej txheem zoo tshaj plaws thiab lub cev muaj zog uas tus neeg tsis tuaj yeem rov ua dua nrog kev pab ntawm cov khoom siv hloov pauv. Qhov no yog vim muaj kev siv dav ntawm cov khoob khoob uas ua los ntawm ntuj ntoo hauv ntau yam kev lag luam. Niaj hnub nimno wood processing technologies thiab kev tsim cov khoom ntoo feem ntau ua rau nws muaj peev xwm muab cov neeg tuaj yeem nrog cov rooj tog zaum, cov khoom siv hauv tsev, kho kom zoo nkauj, tais diav, thiab lwm yam
