Laminated Veneer lumber (LVL) yog cov khoom txua ntoo ua los ntawm ntau txheej ntawm cov ntoo nyias nyias veneer ua ke thiab nias ua ke. Nws muab lub zog siab, seem ruaj khov, thiab kev kho kev cai. Txawm li cas los xij, ntau hom LVL sib txawv hauv cov qauv, ntawv thov, thiab nkag siab txog cov kev sib txawv no tuaj yeem pab koj xaiv cov khoom raug.
Ua ntej, raws li kev tsim khoom, LVL yog cov customized rau hauv tus qauv LVL thiab taw qhia Laminated Veneer lumber (PSL). Txheem Lvl siv cov khoom siv tev los yog hlais cov ntawv sib dhos thiab cov khoom siv hluav taws xob zoo li cov kab ke xws li kab teeb thiab trusses. PSL, ntawm qhov tod tes, siv cov ntoo thinner wood (feem ntau 0.00} 2 mm) uas tau kaw kom nruj thiab ua ke nrog cov khoom siv sib txawv thiab lub zog. Nws feem ntau yog siv hauv kev txhawb nqa qauv rau ntev {}} surges panings lossis siab-nce tsev.
Qhov thib ob, qhov sib txawv ntawm kev ua tau zoo ntawm laminated Veneer lumber (LVL) tau cuam tshuam hauv lawv cov cuab yeej siv thiab kav ntev. Thaum tus qauv Lvl muaj lub zog tsis muaj zog, nws yuav qis me ntsis dua li cov khoom tawv tawv. Txawm li cas los xij, nws muaj cov kev ruaj khov nyob ruaj khov thiab tsis tshua muaj peev xwm ua rau deformation lossis tawg vim av noo kev hloov pauv. PSL, ntawm qhov tod tes, siv cov qauv denser laminate tus qauv, ua rau muaj zog compressive ntau dua thiab tensile muaj zog, ua kom haum rau nrog kev thauj khoom heev. Tsis tas li ntawd, qee cov laminated lumer lumber undergoes corrosion lossis kho hluav taws kub kom thiaj li txhim kho nws cov chaw nyob sab nraud lossis tshwj xeeb.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, txheem LVL tau siv dav hauv cov chaw nyob thiab cov khoom lag luam hauv pem teb vim nws yooj yim ntawm cov fabrication thiab pheej yig. Siab - muaj zog psp thiab LSL)) feem ntau siv hauv cov ru tsev hnyav, Choj txhawb nqa, choj txhawb nqa.
Thaum kawg, kev ua phooj ywg ib puag ncig kuj tseem yog tus neeg sib txawv ntawm Laminated Veneer lumber (LVL). Los ntawm kev siv me me- txoj kab uas lub taub lossis cov khoom seem ua haujlwm ua cov khoom siv roj hmab, lvling nrog cov qauv rau kev ua kom muaj hav zoov. Qhov kev xaiv ntawm cov nplaum rau ntau hom ntawm laminated veneer lumener tseem cuam tshuam nws txoj kev ua tau zoo ib puag ncig. Piv txwv li, kev nce qib ntawm formaldehyde - Cov khoom noj kom zoo nkauj dua rau kev kho kom zoo sab hauv.
Hauv cov ntsiab lus, muaj ntau ntau hom laminated lumer, thiab lawv cov kev sib txawv tau muab los ntawm cov txheej txheem tsim khoom, cov khoom siv mechanies, thiab cov yam ntxwv ib puag ncig. Xaiv hom yog tuaj yeem ua kom zoo tshaj plaws thiab raug nqi - ua haujlwm tau zoo ntawm tsev qauv.
