Umehluko phakathi kwe-LVL, i-LVB, ne-plywood

Amagama abo ahlukile, ukwakheka kwebhodi nakho kuhlukile, futhi amandla okucindezela nokuqina kuhlukile.
I-LVL, i-LVB, ne-plywood wonke amabhodi anezingqimba eziningi, enziwa ngeglue futhi acindezela izingqimba eziningi ze-wood veneer.
Ngokwezikhombisi-ndlela ezivundlile nezime mpo zohlelo lwe-veneer yokhuni, ingahlukaniswa ibe yi-LVL ne-plywood.
I-Laminated Veneer Lumber, eyaziwa nangokuthi i-LVL (I-Laminated Veneer Lumber), iwuhlobo lwe-veneer eyenziwe ngokhuni oluluhlaza ngokusikwa ngokuzungeza noma ukuhlela.Ngemva kokomiswa nokunamathiswa, ihlanganiswa iqonde okusanhlamvu bese ishisa icindezelwe futhi inamathiselwe.Inezici zesakhiwo ezingenazo ukhuni oluqinile olusahwe: amandla aphezulu, ukuqina okuphezulu, ukuzinza okuhle, kanye nokucaciswa okunembayo, okuphindwe kathathu ngamandla nokuqina kunokhuni oluqinile olusahwe.Lo mkhiqizo ungasetshenziselwa ukwakha izingxenye zesifanekiso, imishayo yokwakha, amaphaneli enqola, ifenisha, i-flooring, i-keel yokuhlobisa igumbi, nezinto zokupakisha, ezinohlu olubanzi lwezicelo.

Ezisezingeni eliphansi ngokuvamile zisetshenziselwa ukwenza i-LVL Scaffolding Planks, i-LVL Formwork Beams, ifenisha, amapaneli ayinhloko yeminyango, kanye nokupakishwa komkhiqizo, kuyilapho lezi ezisezingeni eliphezulu zisetshenziselwa ukwenza imishayo, amakholomu, kanye ne-Structural LVL Beams yezakhiwo zokhuni.
I-LVL yonke ihlelwe ngendlela efanayo, kuyilapho i-plywood ihlelwe ngendlela eyodwa evundlile neyodwa eqondile.Izinhlobo ezimbili zamabhodi zinezakhiwo ezihlukene kanye nomehluko wokusebenza, ngayinye inokugxila kwayo kanye nokuzinza kokuqina, okungabhekwa.

I-LVB iyindlela yokuhlanganisa ama-plywood veneers, futhi inohlelo oluhlukile lwezingubo zokhuni.Kodwa-ke, inani lama-veneers okhuni ahlelwe ngokuvundlile nangobude isikhathi ngasinye awasatshalaliswa ngokulinganayo, okunqunywa ngokuya ngezidingo ezithile (ezifana nezingu-3 ezivundlile, ezi-2 eziqondile, nezi-3 ezivundlile)
Uma ukushuba kuncane kakhulu (imvamisa kube ngaphansi kuka-25mm), i-LVB ivame ukusetshenziswa, ngoba ukwengeza i-transverse veneer kungalawula ukuwohloka kobubanzi bebhodi ngokwezinga elithile.Uma kunesidingo esiphezulu samandla, kungcono ukusebenzisa isakhiwo se-LVL.Ngokuvamile kunezinhlobo ezimbili zamandla ku-LVL: ngaphambili nangaseceleni, futhi ngokuvamile kunezinhlobo ezimbili zokuhlola amandla: amandla okugoba amile kanye ne-elastic modulus.

Umehluko wabo ngokuvamile ungaqedwa ngale ndlela elandelayo:
Ukusetshenziswa: I-LVL veneer laminated timber isetshenziswa ikakhulukazi ezakhiweni nezakhiwo zokhuni;I-plywood isetshenziselwa kakhulu ukuhlobisa, ifenisha, nokupakisha.Yiqiniso, ezinye izimboni zikhiqiza i-LVL efana ne-poplar, engasetshenziswa nasefenisha, ukuhlobisa, nokupakisha.
Isakhiwo: I-LVL laminated veneer ne-Plywood zombili zenziwe nge-veneer yokhuni ngokucindezela okushisayo nokuhlanganisa, kodwa indlela yokuhlela ye-veneer ihlukile.Wonke ama-LVL veneers ahlelwe ngendlela efanayo eduze nokusanhlamvu, futhi isiqondiso se-veneers yokhuni esiseduze siyahambisana;I-Plywood ihlelwe iqonde futhi ivundlile, inezingqimba eziseduze ze-veneers zokhuni eziqondiswe ngokuqondile.
Ukubukeka: Ngakolunye uhlangothi, isakhiwo sihlukile uma sibhekwa ohlangothini olulodwa, kanti ngakolunye uhlangothi, i-Plywood surface nangaphansi ngokuvamile yenziwe ngezikhumba zokhuni ezincane ezifana ne-Okoume, i-Bintangor, i-Red Oak, i-Ash, njll. enhle kakhulu futhi ugcizelele umhlobiso;I-LVL laminated veneer, njengesakhiwo noma impahla yesakhiwo, igcizelela amandla nokuchezuka, kodwa ayinazo izidingo eziphezulu zamaphaneli.
Material: I-LVL laminated veneer yenziwe ngokuyinhloko nge-pine wood+phenolic resin (engangeni manzi, i-formaldehyde release E0), kuyilapho i-Plywood ngokuvamile yenziwe nge-poplar/eucalyptus wood+MR glue (ngokuvamile ifaka umswakama, ukukhululwa kwe-formaldehyde E2, E1, E0).

Umehluko omkhulu phakathi kwalokhu okubili usekubunjweni, ukucindezela okushisayo, nokucubungula okuthunyelwe kwe-veneer.Ngokombono wamasu okukhiqiza, amabhodi e-LVL ayinkimbinkimbi kakhulu ekukhiqizeni nasekucubunguleni izinqubo, kuyilapho i-plywood ilula.
Umehluko ekucutshungulweni kokuqala nasekukhiqizeni unquma insiza yomkhiqizo ehlukene phakathi kwalokhu kokubili.Uma kuqhathaniswa ne-plywood, ibhodi le-LVL linezinzuzo ezengeziwe emandleni, ukuzinza, ukucutshungulwa, ukugoba amalangabi, ukwahlukanisa umsindo, nezinye izici.
