Kusiyana Pakati pa Lvl Ndi Plywood

Kusiyana pakati pa lvl ndi plywood

Kusiyana kwakukulu ndikuti makulidwe a veneer kwa lvl ndi yayikulu, nthawi zambiri kuposa 3 mm; opanda kanthu. lvl makamaka imayang'ana m'malo mwa matabwa ocheka, kugogomezera kukulitsa kwautali wamakina a chinthucho, kuwonetsa anisotropy yamatabwa, pomwe plywood ndikusintha kwa anisotropy yamitengo yachilengedwe, kutsindika ndi isotropic.

Kupaka kwa lvl ndikosiyana ndi plywood:

1) Veneer ya lvl iyenera kuyang'anitsitsa kutsogolo ndi kumbuyo, ndipo iyenera kukhala kumbuyo ndi kumbuyo ndi maso ndi maso pamene ikuyendetsa, apo ayi vuto la deformation la lvl silingathe kuthetsedwa; 2) Mphamvu yamagetsi iyenera kusanjidwa bwino, ndi mphamvu yayikulu Pamene chojambulacho chimayikidwa, chimayikidwa pamwamba, ndipo chofooka chochepa chimayikidwa pakatikati. Ndi njira iyi yokha yomwe ntchito yonse ya veneer laminate ingatsimikizidwe; 3) Veneer laminate imayikidwa pambali pa njere, ndipo chovalacho chimayenda motsatira njira yotalikirapo. 4) Malumikizidwe a mipiringidzo ya veneer amayenera kugwedezeka molingana ndi zofunikira zina, zomwe sizofunikira mawonekedwe amtundu, koma kufunikira kwamphamvu yofananira.

Kukanikizira kotentha kwa veneer ndikosiyana ndi plywood

Chifukwa cha kukula kwakukulu kwa zipangizo zamapangidwe, zimakhala zovuta kugwiritsa ntchito makina osindikizira amitundu yambiri komanso akuluakulu ofanana ndi plywood, koma kutulutsa kwa makina osindikizira amodzi kumakhala kochepa, ndipo kutalika kwake sikungapitirire mpaka kalekale chifukwa cha mavuto a mtengo. Poganizira zomwe zili pamwambazi, zikafunika kuonjezera zotulukapo, ndizomveka kugwiritsa ntchito makina osindikizira awiri, osanjikiza atatu kapena anayi kuti apange ma veneer laminates. Vuto lina popanga ma structural veneer laminates ndi kutalika kwa makina osindikizira. [1-2] Kusakwanira kwa mankhwala kutalika.
