Qhov txawv ntawm Lvl thiab Plywood

Qhov txawv ntawm lvl thiab plywood

Qhov sib txawv tseem ceeb yog qhov tuab ntawm veneer rau lvl yog qhov loj, feem ntau ntau dua 3 hli; dawb paug. lvl feem ntau yog tsom rau kev hloov cov ntoo sawn, hais txog kev txhim kho ntawm cov khoom siv kho qhov ntev ntawm cov khoom, qhia txog anisotropy ntawm cov ntoo, thaum plywood yog kev hloov pauv ntawm anisotropy ntawm ntuj ntoo, hais txog isotropic.

lvl paving yog txawv ntawm plywood:

1) Lub veneer ntawm lvl yuav tsum tau xyuam xim rau pem hauv ntej thiab nraub qaum, thiab nws yuav tsum rov qab-rau-rov qab thiab lub ntsej muag-rau-lub ntsej muag thaum paving, txwv tsis pub cov teeb meem deformation ntawm lvl tsis tuaj yeem daws tau; 2) Lub zog ntawm cov veneer yuav tsum tau txheeb xyuas kom zoo, nrog lub zog siab Thaum lub veneer yog paving, nws muab tso rau ntawm txheej txheej, thiab cov veneer tsis muaj zog yog muab tso rau ntawm cov tub ntxhais txheej. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tiav tag nrho ntawm veneer laminate; 3) Lub veneer laminate yog paved raws cov nplej, thiab cov veneer khiav raws txoj kab ntev. 4) Cov pob qij txha ntawm veneer miter pob qij txha yuav tsum tau staggered raws li qee qhov kev xav tau nyob rau hauv lem, uas tsis yog qhov yuav tsum tau ntawm cov tsos zoo, tab sis qhov yuav tsum tau muaj lub zog sib xws.

Qhov kub nias ntawm veneer yog txawv ntawm cov plywood

Vim qhov loj ntawm cov khoom siv, nws yog ib qho nyuaj rau siv ntau txheej thiab loj-txheej presses zoo ib yam li plywood, tab sis cov zis ntawm ib-txheej presses yog tsawg, thiab nws ntev yuav tsis tau ncua mus tas li vim muaj teeb meem nqi. Xav txog cov xwm txheej saum toj no, thaum nws yuav tsum tau ua kom cov zis ntau ntxiv, nws yog qhov tsim nyog los siv ob txheej, peb txheej lossis plaub txheej xovxwm rau kev tsim cov veneer laminates. Lwm qhov teeb meem hauv kev tsim cov txheej txheem veneer laminates yog qhov ntev ntawm cov xovxwm. [1-2] Cov khoom ntev tsis txaus.
