Umehluko Phakathi Kwe-Lvl Ne-Plywood

Umehluko phakathi kwe-lvl ne-plywood

Umehluko omkhulu ukuthi ubukhulu be-veneer ye-lvl bukhulu kakhulu, ngokuvamile bungaphezu kuka-3 mm; ngenalutho. I-lvl ihloselwe kakhulu ukufaka esikhundleni sokhuni olusahliweyo, kugcizelela ukuthuthukiswa kwezakhiwo zemishini yobude bomkhiqizo, okugqamisa i-anisotropy yokhuni, kuyilapho i-plywood iwukuguqulwa kwe-anisotropy yokhuni lwemvelo, okugcizelela ukuthi isotropic.

I-lvl paving ihlukile ku-plywood:

1) I-veneer ye-lvl kufanele inake ngaphambili nangemuva, futhi kufanele ibuyele emuva futhi ibhekane ubuso nobuso lapho igandaywa, ngaphandle kwalokho inkinga yokuguqulwa kwe-lvl ayikwazi ukuxazululwa; I-2) Amandla we-veneer kufanele ahlungwe kahle, ngamandla aphezulu Lapho i-veneer igandayiwe, ibekwe phezu koqweqwe olungaphezulu, futhi i-veneer ebuthakathaka ibekwe phezu kohlaka oluyisisekelo. Kungale ndlela kuphela lapho ukusebenza okuphelele kwe-veneer laminate kungaqinisekiswa; 3) I-laminate ye-veneer igandaywe eduze nokusanhlamvu, futhi i-veneer ihamba ngendlela ye-longitudinal. 4) Amalunga amajoyinti e-veneer miter kufanele anyakaze ngokuya ngezidingo ezithile zesikhawu ngokulandelana, okungeyona imfuneko yekhwalithi yokubukeka, kodwa imfuneko yamandla afanayo.

Ukucindezela okushisayo kwe-veneer kuhlukile kulokho kwe-plywood

Ngenxa yobukhulu obukhulu bezinto zokwakha, kunzima ukusebenzisa izingqimba eziningi ze-multi-layer kanye nefomethi enkulu efana ne-plywood, kodwa ukukhishwa komshini wokunyathelisa okukodwa kuphansi, futhi ubude bawo abukwazi ukunwetshwa ngokungapheli ngenxa yezinkinga zezindleko. Uma kucatshangelwa lezi zici ezingenhla, lapho kudingekile ukwandisa umkhiqizo, kunengqondo ukusebenzisa ungqimba oluphindwe kabili, ungqimba oluthathu noma ungqimba olune umshini wokukhiqiza ama-veneer laminates. Enye inkinga ekukhiqizeni i-structural veneer laminates ubude bomshini wokunyathelisa. [1-2] Ubude bomkhiqizo obanele.
