LVL, LVB, le plywood kaofela ke liboto tse nang le mekhahlelo e mengata, tse entsoeng ka sekhomaretsi le ho hatella likarolo tse ngata tsa veneer ea lehong.
Ho ea ka litaelo tse otlolohileng le tse otlolohileng tsa tlhophiso ea veneer ea lehong, e ka aroloa ka LVL le plywood.
Laminated Veneer Lumber, eo hape e tsejoang e le LVL (Laminated Veneer Lumber), ke mofuta oa veneer e entsoeng ka lehong le tala ka ho seha ka rotary kapa planing.Ka mor'a ho omisoa le ho khomarela, e bokelloa ka lehlakoreng la lijo-thollo ebe e chesa e hatelloa le ho khomareloa.E na le litšobotsi tsa sebopeho tseo lepolanka le tiileng le sakhang le se nang tsona: matla a holimo, ho tiea ho hoholo, botsitso bo botle, le lintlha tse nepahetseng, tse matla le ho thatafala ka makhetlo a mararo ho feta lehong le tiileng le sakhang.Sehlahisoa sena se ka sebelisoa bakeng sa ho haha likarolo tsa template, maballo a mohaho, liphanele tsa likoloi, thepa ea ka tlung, fatše, mokhabiso oa kamore ea lehong keel, le lisebelisoa tsa ho paka, tse nang le mefuta e mengata ea likopo.
Ka kakaretso tse tlaase li sebelisoa ho etsa LVL Scaffolding Planks , LVL Formwork Beams, thepa ea ka tlung, liphanele tsa mantlha tsa menyako, le liphutheloana tsa lihlahisoa, ha tse phahameng li sebelisetsoa ho etsa maballo, litšiea, le Mehaho ea Structural LVL bakeng sa mehaho ea lehong.
LVL kaofela e hlophisitsoe ka nqa e le 'ngoe, ha plywood e hlophisitsoe ka tsela e le 'ngoe e otlolohileng le e otlolohileng.Mefuta e 'meli ea mapolanka e na le mekhoa e fapaneng le liphapang tsa ts'ebetso, e' ngoe le e 'ngoe e na le maikutlo a eona le botsitso ba ho tiea, e ka hlahlojoang.
LVB ke mokhoa oa ho kopanya li-veneers tsa plywood, hape e na le tlhophiso e fapaneng ea liphahlo tsa lehong.Leha ho le joalo, palo ea li-veneers tsa lehong tse hlophisitsoeng ka mokhoa o otlolohileng le ka nako e telele nako le nako ha li aroloe ka ho lekana, tse laetsoeng ho ea ka litlhoko tse khethehileng (tse kang 3 tse rapameng, tse 2 tse otlolohileng, le tse 3 tse tšekaletseng)
Haeba botenya bo batla bo le tšesaane (hangata bo ka tlase ho 25mm), joale LVB e sebelisoa ka kakaretso, hobane ho eketsa li-transverse veneer ho ka laola deformation ea bophara ba boto ho isa tekanyong e itseng.Haeba ho na le tlhokahalo e phahameng ea matla, joale ho molemo ho sebelisa sebopeho sa LVL.Ka kakaretso ho na le mefuta e 'meli ea matla ho LVL: ka pele le ka lehlakoreng,' me ka kakaretso ho na le mefuta e 'meli ea tlhahlobo ea matla: matla a ho kobeha a tsitsitseng le modulus elastic.
Hangata, phapang ea bona e ka hlalosoa ka tsela e latelang:
Tšebeliso: LVL veneer laminated lehong le sebelisoa haholo-holo mehahong le mehaho ea mapolanka;Plywood e sebelisoa haholo bakeng sa mokhabiso, thepa ea ka tlung le ho paka.Ke ’nete hore lifeme tse ling li hlahisa LVL e kang popoliri, e ka sebelisoang le ho etsa thepa ea ka tlung, ho khabisa le ho paka.
Sebopeho: Veneer ea laminated ea LVL le Plywood ka bobeli li entsoe ka veneer ea lehong ka ho tobetsa ho chesang le ho kopanya, empa tataiso ea tlhophiso ea veneer e fapane.Li-veneers tsohle tsa LVL li hlophisitsoe ka tsela e le 'ngoe hammoho le lijo-thollo,' me tataiso ea lihlopha tse haufi tsa lehong li tšoana;Plywood e hlophisitsoe ka mokhoa o otlolohileng le o otlolohileng, ka likarolo tse haufi tsa mapolanka a lebisitsoeng holimo.
Ponahalo: Ka lehlakoreng le leng, sebopeho se fapane ha se talingoa ka lehlakoreng le leng, 'me ka lehlakoreng le leng, bokaholimo ba Plywood le tlase hangata bo entsoe ka matlalo a lehong a masesaane joalo ka Okoume, Bintangor, Red Oak, Ash, joalo-joalo. e ntle haholo mme e hatisa mokhabiso;LVL laminated veneer, e le mohaho kapa thepa ea mohaho, e hatisa matla le ho kheloha, empa ha e na litlhoko tse phahameng tsa liphanele.
Boitsebiso: LVL laminated veneer e entsoe haholo-holo ka lehong la phaene + phenolic resin (e sa keneleng metsi, formaldehyde e lokolloa E0), ha Plywood hangata e entsoe ka poplar/eucalyptus wood+MR glue (ka kakaretso e thibela mongobo, e lokolloa formaldehyde E2, E1, E0).
Phapang e kholo ka ho fetisisa pakeng tsa tse peli e itšetlehile ka sebopeho, ho hatella ho chesang, le ho sebetsa ka poso ea veneer.Ho latela pono ea mekhoa ea tlhahiso, mapolanka a LVL a rarahane haholoanyane mekhoeng ea tlhahiso le ho sebetsa, ha plywood e batla e le bonolo.
Liphapang tsa ts'ebetso ea pele le tlhahiso li etsa qeto ea tšebeliso e fapaneng ea sehlahisoa pakeng tsa tse peli.Ha ho bapisoa le plywood, boto ea LVL e na le melemo e mengata ho matla, botsitso, ts'ebetso, ho lieha ha lelakabe, ho kenya molumo, le likarolo tse ling.
