Umgangatho olungileyo weBalsa Strips evela e-Ecuador
I-Ochroma Pyramidale, eyaziwa ngokuba ngumthi we-balsa, ngumthi omkhulu, okhula ngokukhawuleza owazalelwa eMelika. Lilungu lodwa le-genus Ochroma. Igama elithi balsa livela kwigama lesiSpanish elithi "raft".
I-angiosperm evuthulukayo, iOchroma pyramidale inokukhula ifike kuma-30m ubude, kwaye ihlelwa njengeplanga eliqinileyo nangona umthi wona uthambile kakhulu; ngowona mthi worhwebo uthambileyo kwaye usetyenziswa kakhulu kuba unobunzima obulula.
I-Balsa Strips inokudityaniswa kwiibhloko ze-balsa ezisetyenziswa kwiincakuba ze-injini yomoya njengemathiriyeli engundoqo yesakhiwo.
Umthi weBalsa udla ngokusetyenziswa njengento engundoqo kwii-composites; umzekelo, iincakuba zeeinjini zomoya ezininzi ziyinxalenye ye-balsa. I-End-grain balsa yinto ephambili enomtsalane kwiincakuba zomoya ngenxa yokuba ayibizi kakhulu kwaye ixinene ngokwaneleyo ukunika amandla amakhulu kunogwebu, uphawu oluluncedo ngakumbi kwicandelo leengcambu ze-cylindrical zeblade. Isitokhwe sephepha leplanga le-Balsa sisikwa ngokwemilinganiselo echaziweyo, ifakwe amanqaku okanye i-kerfed (kuzo zombini ubude nobubanzi, njengoko kubonisiwe, kwiigophe ezidityanisiweyo) kwaye emva koko ibhalwe kwaye idityaniswe ngababoneleli abaphambili kwiikhithi.
Kuphela i-40% yomthamo weqhekeza le-balsa yinto eqinileyo. Isizathu sokuba ikwazi ukuma mde kwaye yomelele ehlathini kukuba eneneni izaliswe ngamanzi amaninzi, njengetayara elizele ngumoya. Xa i-balsa ilungiswa, amaplanga afakwa kwi-oven aze agcinwe apho iiveki ezimbini ukuze kususwe onke amanzi angaphezulu. Amagqabi einjini yomoya enziwe ngomthi we-balsa odityaniswe phakathi kwamasuntswana amabini efiberglass. Kwimveliso yorhwebo, iinkuni zomiswa kwiziko malunga neeveki ezimbini, zishiya iiseli zingenanto kwaye zingenanto. Umlinganiselo omkhulu wevolumu ukuya kumphezulu wesiphumo esincinci, iiseli ezingenanto zinika iinkuni ezomileyo umlinganiselo omkhulu wamandla-to-ubunzima kuba iiseli zingumoya.
