Umahluko phakathi kweLvl kunye nePlywood

Umahluko phakathi kwe-lvl kunye neplywood

Umahluko omkhulu kukuba ubukhulu be-veneer ye-lvl bukhulu kakhulu, ngokubanzi ngaphezu kwe-3 mm; blank. I-lvl ijolise ikakhulu ekutshintsheni amaplanga asarhayo, kugxininise ukuphuculwa kweepropathi zoomatshini bexesha elide lemveliso, iqaqambisa i-anisotropy yomthi, ngelixa i-plywood iyinguqu ye-anisotropy yomthi wendalo, kugxininiswa isotropic.

I-lvl paving yahlukile kwiplywood:

I-1) I-veneer ye-lvl kufuneka inikele ingqalelo ngaphambili nangasemva, kwaye kufuneka ibuyele emva kunye nobuso ngobuso xa i-paving, ngaphandle koko ingxaki yokuguqulwa kwe-lvl ayinakusonjululwa; I-2) Amandla e-veneer kufuneka ahlelwe ngokufanelekileyo, ngamandla aphezulu Xa i-veneer ihlanjululwa, ifakwe kwi-surface layer, kwaye i-veneer ebuthakathaka ifakwe kwi-core layer. Kuphela ngale ndlela kuya kuqinisekiswa ukusebenza ngokubanzi kwe-laminate ye-veneer; 3) I-laminate ye-veneer igayiwe ecaleni kweenkozo, kwaye i-veneer ihamba ngendlela ye-longitudinal. 4) Amalungu e-veneer miter joints kufuneka adideke ngokweemfuno ezithile zekhefu ngokulandelelana, okungekho mfuneko yomgangatho wembonakalo, kodwa imfuneko yokuqina okufanayo.

Ukucofa okushushu kweveneer kwahlukile kuleyo yeplywood

Ngenxa yobukhulu obukhulu bezinto zokwakha, kunzima ukusebenzisa i-multi-layer kunye ne-fomat-format presses efana ne-plywood, kodwa imveliso yokushicilela i-single-layer iphantsi, kwaye ubude bayo abunakwandiswa ngokungapheliyo ngenxa yeengxaki zeendleko. Ukuqwalasela le miba ingentla, xa kufuneka ukwandisa imveliso, kunengqiqo ngakumbi ukusebenzisa i-double-layer, i-layer-three okanye i-press-layer press for production of veneer laminates. Enye ingxaki kwimveliso ye-structural veneer laminates ubude bokushicilela. [1-2] Ubude bemveliso obungonelanga.
