Plywood em i wanpela bilong ol diwai we planti manmeri i save yusim long wok konstraksen, wokim ol fenija, pinisim ol samting insait long haus, na ol wok insait long indastri. Tasol maski em i stap planti, planti baia, disaina, na tu ol wokman bilong indastri i no gat klia save long hau ol i save makim 'plywood'.
Gutpela save long ol kain kain 'plywood' em i bikpela samting long mekim ol gutpela disisen long baim ol samting, stretim ol wok bilong wokim ol samting, na mekim gutpela wok long ol prodak.
Dispela atikol i givim wanpela gutpela, profesenel 'breakdown' bilong ol 'plywood' klasifikesen stat long straksa na kain bilong en i go inap long wok na rot bilong prosesim.
1. Save long as bilong 'Plywood'
Ol i wokim 'plywood' longtripela o moa leia bilong ol 'veneer'(ol liklik hap diwai), planti bilong ol i save kamap long rot bilong katim. Long strongim straksa, planti taim ol i save wokim 'plywood' insait long'odd-numbered layers-planti taim 3-pela, 5-pela, o 7-pela.
Olgeta wan wan 'veneer' leia i stap stretperpendikulai go long wanpela we i stap klostu, na i kamapim wanpela 'cross-grain structure' we i kamap gutpela moa:
Strong bilong bendim
Dimensenel stebiliti
Em i no inap long bruk na bruk
Ol as samting bilong straksa em:
Pes 'veneer'– antap, ples we yu ken lukim
Back veneer– narapela sait bilong pes
Ol 'core veneers'– ol insait leia, we i makim strong bilong masin
Kain, gret, na lukluk bilong 'face veneer' i save makim gutpela na maket posisen bilong 'plywood'.
2. Spesies-Klasifikesen: Hau kain diwai i save makim 'plywood'
Planti taim ol i save makim 'plywood' bihainimkain bilong pes veneer, long wanem, dispela leia i save bagarapim lukluk, wok bilong masin, na wok bilong en.
Ol kain strongpela diwai we planti manmeri i save yusim em:
Basswood
Sit bilong paia
Birch
Poplar
Elm
Maple
Beech
Okoume
Eucalyptus
Ol i save yusim 'hardwood plywood' long wokim ol fenija, ol kabot, bilasim haus, na ol wok we i nidim gutpela kwaliti o strong bilong masin.
Ol 'softwood' we planti manmeri i save yusim em:
Radiata Pine
Spruce
Lach
Masson Pine
Ol 'softwood plywood' em i lait, strongpela, na planti taim ol i save yusim long wokim ol haus, putim ol samting insait long ol paket, na wokim ol samting long haus.
3. Klasifikesen long Kain Diwai: Hatwut na Sofwut Plywood
Long sait bilong indastriel, ol i brukim 'plywood' i go long:
Hatwut plaiwut– planti taim ol i save tingim lukluk bilong en, strong bilong en, na strong bilong en
Softwood plywood– ol i save yusim planti long ol wok bilong wokim haus, indastriel, na konstraksen
Olgeta wan wan kategori i stret long ol narapela narapela nid bilong maket na ol kos straksa.
4. Klasifikasen long pinis bilong yusim: Jeneral vs. Spesel Plywood
Jeneral-pepos plaiwut
Ol i wokim bilong planti kain wok olsem:
Sia na tebol
Kabinet
Ol wol insait
Pakejing
Dispela em i nambawan samting ol i save salim long ol global maket.
Spesel plaiwut
Ol i wokim bilong ol spesifik pefomens rikwaemen, olsem:
Marine plywood(i no inap kisim wara)
Anti-slip plywood(bilong ol trela, kontena, plua)
Fomwok plaiwut(konstraksen-yusim)
Plaiwut we i no gat nois o i gat mak bilong paia
Fleksibel plaiwut(long ol benk pes)
Ol dispela prodak i nidim stretpela 'adhesive' fomulasen na strongpela proses kontrol.
5. Klasifikesen long Bonding Pefomens: Klas I-IV
Long Saina na planti intenesenel maket, ol i save makim tu 'plywood' long 'bonding durability' bilong ol 'adhesive layers' bilong en.
Klas I - Weather & Boil Proof (WBP)
Em inap long sanap strong long wara i boil, stim, na ausait
Em i gutpela long solwara, ausait, na hai- aplikesen we i gat planti wara
Klas II - Wara-I no inap long sakim
Em i no inap long go insait long kol wara na sampela taim wara i hat
Em i no gutpela long boilim o stap long wara oltaim
Klas III - Moisture-Resistant
Em inap long karim sotpela taim wara
Planti taim ol i save yusim long wokim ol fenija insait long haus na ol narapela samting insait long haus
Klas IV - Non-Moisture-Resistant
Em i gutpela long ol ples we i no gat wara insait long haus tasol
I givim strong bilong pasim ol samting
Long ol baia long wol, pefomens bilong 'adhesive' em i wanpela bikpela samting we i save mekim wok bilong makim prodak.
6. Klasifikasen long straksa komposesen
Ol narapela narapela intanel straksa i save helpim ol narapela narapela wok nid.
(1) Standet Plywood
Ol i wokim olgeta long ol 'cross-laminated veneers-na em i gutpela long yusim insait long haus na ol samting we i no insait long haus.
(2) Core Blockboard / Lumber Core Plywood
Ol i wokim wantaim wanpela strongpela diwai blok we i stap namel long ol 'face veneer'.
Ol gutpela samting:
Gutpela strong bilong holim skru
Strongpela straksa i antap moa
Daunim hevi bilong 'warping'
Planti taim ol i save yusim long ol bikpela fenija, dua, na ol samting insait long haus.
(3) Komposit Plywood
Ol i senisim wanpela o moa leia wantaim ol 'engineered substrates' olsem:
MDF
HDF
OSB
Particleboard
Planti taim ol i save yusim long skelim kos, hevi, na pefomens.
7. Klasifikasen long Surface Tritmen
Pasin bilong pinisim 'surface' i save makim lukluk bilong en, strong bilong en, na wok bilong en.
(1) Sanded Plywood (S2S o S1S)
Smutpela pes, i gutpela long penim o laminetim.
(2) Polished/Planed Plywood
Wanpela gutpela rot bilong pinisim we i save mekim 'surface texture' i kamap gutpela moa.
(3) Veneered Plywood
Kavremap wantaim:
Dekoretiv naturela diwai veneer
Pepa karamapim
PVC film
Metal foil
Hai-presa laminet (HPL)
Em i gutpela long ol fenija na insait disain.
(4) Pre-finis Plywood
Factory-kotim wantaim:
UV koting
Lak
Pinis bilong melamin
Stein
Redi long putim na i no gat moa wok bilong pinisim long ples.
8. Klasifikesen long Seip: Flet o Molded Plywood
Maski planti 'plywood' i flat, ol i save presim 'plywood' we ol i wokim longol ben o 3D seipyusim ol spesel mol.
Ol aplikesen i gat:
Baksait bilong sia na ol sia
Ol wol panel we i ben
Ol akostik wev panel
Insait bilong kar
Plywood we ol i wokim long 'molded' i makim ples we wok bilong wokim ol samting na wok bilong wokim ol samting bilong nau i bung.
9. Rot bilong wokim: Stat long 'Log' i go inap long 'Finish Panel'
Rot we ol i save yusim emdrai-hot presing proses, we i gat:
Log seleksen na trimim
Log kondisening (bikpela step)
Senta na tanim skin
Draim 'veneer'
Aplikesen bilong glu
Putim-ap na bungim
Kol presing
Hot presing
Katim, sendim, gredim
Bilong wanem 'log conditioning' em i bikpela samting
Ol rot i gat:
Hot wara i sokim
Wota na win i hatim wantaim
Stim tritmen
As tingting bilong en em long mekim 'log' i kamap malumalum, mekim 'veneer' i kamap wankain, na mekim prodak i stap gut.
