Laminated Veneer lumber (LVL) yog qhov siab - Performed wood engineer nplooj ntawv uas tau qhuav, thiab ces laminated nyob rau hauv qhov kub thiab siab. Nws cov txheej txheem tsim muaj kev puas tsuaj los ntawm lub zog ntuj ntawm cov ntoo thaum kov yeej cov ntoo muaj teeb meem zoo li cov ntaub pua ntoo, thiab tsis muaj qhov tsis txaus ntseeg los ntawm kev ua haujlwm Lamination.
Micrl's Veneer txheej yog feem ntau yog npaj nrog cov nplej, lub ntsiab lus ntawm txhua qhov ntev ntawm cov khoom siv, muab lub zog Axial zoo heev thiab txhav. Cov fibers ntawm cov pas dej ib sab tuaj yeem sib piv lossis hla - laminated. Thaum npaj cov kev ua kom sib dhos, LVL cov khoom pov thawj zoo ntev tensile thiab compressive cov khoom, ua rau nws haum rau thauj khoom {{}} Cov ris ris cov kabmob kab thiab kab. Hla - laminarization ntawm qee qhov venerets cov khaubncaws sab nraud povtseg kom ruaj khov thiab shear tiv taus. Kev xaiv ntawm cov nplaum kuj tseem cuam tshuam cuam tshuam ncaj qha; Phenolic Resin lossis {-} formaldehyde resin feem ntau siv los xyuas kom muaj kev sib raug zoo thiab ruaj khov.
LVL cov txheej txheem kev sib tw muaj kev sib tw muaj cov txiaj ntsig tseem ceeb hauv kev siv daim ntawv thov engineering. Piv rau cov ntoo khov kho, lvl tshem tawm cov kev cuam tshuam ntawm qhov tsis xws luag pom, muaj kev ruaj khov siab ruaj khov, thiab tsis tshua muaj kev tawg lossis tawg. Nws qhov loj me tso cai rau txoj kev sib tw ntawm ntev-} spa span ci thiab txhim kho kev sib koom tes thiab txhim kho kev ua haujlwm. Tsis tas li ntawd, LVL tuaj yeem hloov kho nws txoj kev ua tiav los ntawm kev kho cov naj npawb ntawm venerets thiab tuab kom tau raws li cov kev xav tau muaj ntau lub tsev.
Hais txog kev nyab xeeb, lvl siv me me -} Lub cev ntaj cua daj, thiab ua kom zoo nkauj nrog kev lom zem. Nws cov qauv tsim khoom tsim cov qauv khoom siv tseem txo cov khoom pov tseg, ua rau nws tsis tseem ceeb {} Kev ua tau zoo cov khoom siv hauv kev tsim kho niaj hnub no.
