Zoo Zoo Balsa Sawb los ntawm Ecuador
Ochroma Pyramidale, feem ntau hu ua tsob ntoo balsa, yog tsob ntoo loj, loj hlob sai tuaj rau Asmeskas.Nws yog ib tug tswv cuab ntawm genus Ochroma.Lub npe balsa los ntawm lo lus Spanish rau "raft".
Ib tug deciduous angiosperm, Ochroma pyramidale tuaj yeem loj hlob mus txog 30m siab, thiab raug cais raws li cov ntoo tawv txawm tias cov ntoo nws tus kheej yog mos heev; t yog cov khoom muag muag muag muag thiab siv dav vim nws yog lub teeb yuag.
Balsa Strips tuaj yeem muab khi rau hauv balsa blocks siv hauv cua turbine hniav ua cov ntaub ntawv tseem ceeb.
Balsa ntoo feem ntau yog siv los ua cov khoom tseem ceeb hauv cov khoom sib xyaw;Piv txwv li, cov hniav ntawm ntau cov cua turbines yog ib feem ntawm balsa.End-grain balsa yog cov khoom tseem ceeb txaus nyiam rau cov cua tshuab vim nws yog qhov pheej yig thiab ntom txaus kom muaj zog ntau dua li cov foams, ib qho tseem ceeb tshwj xeeb tshaj yog muaj txiaj ntsig tshwj xeeb hauv cov ntsiab lus cylindrical hauv paus ntawm cov hniav.Balsa wood sheet stock yog txiav rau qhov ntev, tau qhab nia los yog kerfed (raws li ob qho tib si ntev thiab dav, raws li qhia, rau qhov sib xyaw nkhaus) thiab tom qab ntawd sau thiab sau los ntawm cov neeg muab khoom tseem ceeb rau hauv cov khoom siv.
Tsuas yog 40% ntawm qhov ntim ntawm ib daim ntawm balsa yog ib qho khoom siv.Qhov laj thawj yog vim li cas nws tuaj yeem sawv siab thiab muaj zog hauv hav zoov yog qhov tseeb tias nws tau ntim dej ntau, zoo li lub log tsheb uas muaj huab cua.Thaum cov balsa ua tiav, cov ntoo tau muab tso rau hauv lub qhov cub thiab khaws cia rau ob lub lis piam kom tshem tawm tag nrho cov dej ntau dhau.Cua turbine hniav yog tsim los ntawm balsa ntoo uas yog sandwiched ntawm ob me me ntawm fiberglass.Rau kev lag luam ntau lawm, ntoo yog kiln-qhuav rau li ob lub lis piam, tawm hauv lub hlwb hollow thiab khoob.Qhov loj ntim-rau-nto qhov sib piv ntawm qhov ua rau nyias-walled, khoob hlwb muab cov ntoo qhuav ib qho loj-rau-qhov hnyav piv vim tias cov hlwb feem ntau yog huab cua.
