Kev txua ntoo yog qhov chaw ua khes mis thiab siv thev naus laus zis. Lawv sib tshooj rau ntau txoj kev, tab sis tseem sawv cev rau ob qho kev lag luam - woodworking thiab pulp thiab ntawv.
Cov Lus Qhia

Kev ua cov ntoo yog cais raws li qhov thev naus laus zis thiab cov yam ntxwv rau kev pom, npaj ua, txiav, txiav, txiav, tee, poob, poob. Qhov no yog ua raws li los ntawm gluing thiab hammering, spiking, ziab thiab tiv thaiv impregnation. Cov impregnations tshwj xeeb tuaj yeem siv los txhim kho cov khoom thiab tiv thaiv kev kho mob tshwj xeeb ntawm thaj chaw. Sawing, phiaj xwm thiab milling yog cov lus pom zoo thiab cov txheej txheem ncaj. Nrog kev pab ntawm lub sawmills tshwj xeeb nruab rau ntawm lub sawmills, lub cav nrog thiab tsis muaj tawv ntoo yog hloov mus rau hauv kab teeb, daim hlau lossis cov laug cam. Nyob rau tib lub sijhawm, ntau cov shavings thiab sawdust raug tsim, uas qee zaum qee feem ua tiav, tab sis ntau feem ntau hlawv.

Nyob ntawm seb siv ntoo ua li cas, khib nyiab los ntawm kev tsim khoom tuaj yeem yog 35-45%. Qhov no tsis yog tsuas yog sawdust thiab shavings, tab sis kuj tseem trimmings, bark, slab - tag nrho cov pov tseg no tuaj yeem rov siv dua. Cov khib nyiab los ntawm kev tsim ntoo ua tiav rau kev ua tiav zoo ntxiv yog txheeb raws li hauv qab no - nyuaj, lossis cov tawv nqaij, tawv thiab mos - ua haujlwm zoo thiab sawdust. Cov khib nyiab tau muab faib rau cov uas tau txais thaum lub sijhawm hav zoov, thaum siv cov cav ntoo thiab thaum lub sijhawm ua thawj thiab theem nrab. Tom qab ntawd sawdust tuaj yeem siv rau hauv cov nroj tsuag hydrolysis, hauv kev tsim cov av cib thiab gypsum nplooj ntawv. Cov phaj yog tsim los ntawm kev shavings: wood-shaving thiab cement-shaving. Kev lag luam ntawm cov roj briquettes los ntawm cov khib nyiab ntoo tseem tau txais cov koob meej. Kev ua liaj ua teb kuj siv ntau cov pov tseg ntawm cov txheej txheem ntoo.

Thaum npaj cov khib nyiab ntoo rau kev ua, lawv tau txheeb los ntawm cov hom ntoo, tom qab ntawd raug rau kev kho hydrothermal, txiav, thiab thaj chaw tsis zoo yuav raug tshem tawm. Hauv cov tshuab tshwj xeeb, pliaj, kho ua ntej nrog chav, yog hauv av nrog cov hniav to tshwj xeeb. Cov ntoo khoob ntxiv tau kho nrog ntsev cov tshuaj daws kom tshem tau cov teeb meem tsis zoo ntawm cov ntoo uas tuaj yeem tshwm sim los ntawm kev sib chwv nrog dej phwj lossis cov av tsis huv.

Cov npe ntawm cov khoom siv tuaj yeem sib txawv raws li cov kev taw qhia ntawm cov txheej txheem pov tseg, tab sis cov tshuab yuav tsum tau ua thiab cov tshuab ua haujlwm feem ntau zoo li qub. Cov no yog cov tes xuas nrig ntaus, lub tshuab nias, cov chippers, cov chaw sib xyaw, ntsia hlau conveyors thiab chav qhuav. Cov pwm lossis lub ncaig hluav ncaig, lub cav ntoo kom sib txig yuav tsum tau. Kev ua cov ntoo tiag tiag muaj ntau thaj chaw tshwj xeeb. Koj xav tau koj tus kheej cov khoom siv rau kev tsim cov ntawv, chipboard lossis hluav ncaig, yog li nws tsis zoo li nws tuaj yeem ua tiav cov ntoo hauv txhua qhov kev qhia ib zaug.
