Yini i-plywood

I-Plywoodingenye yemikhiqizo yephaneli esekelwe ngokhuni esebenza ngezindlela eziningi futhi eyaziwa kabanzi esetshenziswa kuwo wonke amaphrojekthi okwakha ahlukahlukene emhlabeni wonke.Idalwe ngokubopha i-resin kanye namashidi e-veneer yokhuni ukuze kwakheke into eyinhlanganisela ethengiswa ngamaphaneli.Ngokuvamile, izici ze-plywood zibhekana nama-veneers ebanga eliphakeme kunama-core veneers.Umsebenzi oyinhloko wezingqimba eziwumgogodla ukwandisa ukuhlukana phakathi kwezingqimba zangaphandle lapho izingcindezi zokugoba ziphakeme kakhulu, ngaleyo ndlela kuthuthukiswe ukumelana namandla okugoba.Lokhu kwenza i-plywood ibe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezidinga amandla nokuguquguquka.

Isingeniso sezinqubo zokukhiqiza

I-Plywood, evame ukubizwa ngokuthi ibhodi elinezingqimba eziningi, ibhodi le-veneer, noma ibhodi eliwumgogodla, yenziwa ngokusika ama-veneers ezingxenyeni zamalogi bese ihlanganiswa futhi iwashise ibe yizingqimba zebhodi ezintathu noma ngaphezulu (inombolo eyinqaba).Inqubo yokukhiqiza i-plywood ihlanganisa:

Ukusika izingodo, ukuxebula, nokusika izingodo; Ukomisa okuzenzakalelayo; Ukuhlanganisa okuphelele; Ukuhlanganiswa kwe-Gluing ne-billet; Ukucindezela okubandayo nokulungisa; Ukucindezela okushisayo nokwelapha; Ukusaha, ukuklwebha, nokugawula isihlabathi; Ukucindezelwa kathathu, ukulungisa kathathu, ukusaha kathathu, nokusarha kathathu; Ukugcwalisa; Ukuhlolwa komkhiqizo kuqedile; Ukupakisha nokugcina; Ezokuthutha

I-Log Cutting and Peeling

I-peeling iyisixhumanisi esibaluleke kakhulu ekukhiqizeni i-plywood, futhi ikhwalithi ye-veneer ehlutshiwe izothinta ngokuqondile ikhwalithi ye-plywood eqediwe.Izingodo ezinobubanzi obungaphezu kuka-7cm, njenge-eucalyptus kanye ne-miscellaneous pine, ziyasikwa, zihlutshiwe, bese zisikwa zibe imifino enogqinsi olungaphansi kuka-3mm.Ama-veneers ahlutshiwe anokuqina okuhle okufanayo, awathambekele ekungeneni kweglue, futhi anamaphethini amahle e-radial.

Ukomisa Okuzenzakalelayo

Inqubo yokomisa ihlobene nokuma kwe-plywood.Ama-veneers ahlutshiwe adinga ukumiswa ngesikhathi ukuze kuqinisekiswe ukuthi umswakama wawo ufinyelela izidingo zokukhiqiza ze-plywood.Ngemuva kwenqubo yokumisa okuzenzakalelayo, okuqukethwe komswakama we-veneers kulawulwa ngaphansi kwe-16%, i-warpage yebhodi incane, akulula ukuyicisha noma i-delaminate, futhi ukusebenza kokucubungula kwama-veneers kuhle kakhulu.Uma kuqhathaniswa nendlela yendabuko yokomisa yemvelo, inqubo yokomisa ngokuzenzekelayo ayithinteki isimo sezulu, isikhathi sokumisa sifushane, umthamo wokomisa nsuku zonke unamandla, ukusebenza kahle kokumisa kuphakeme, isivinini siyashesha, futhi umphumela ungcono.

Ukuhlanganisa Okugcwele, i-Gluing, kanye ne-Billet Assembly

Indlela ye-splicing kanye ne-adhesive esetshenzisiwe inquma ukuzinza kanye nobungane bemvelo bebhodi le-plywood, okubuye kube yinkinga ethintekayo kakhulu kubathengi.Indlela yakamuva yokuhlanganisa embonini iyindlela egcwele yokuhlanganisa kanye nesakhiwo se-toothed splicing.Ama-veneers omisiwe futhi ahlutshiwe ahlanganiswe ebhodini elikhulu lonke ukuze kuqinisekiswe ukunwebeka okuhle nokuqina kwama-veneers.Ngemuva kwenqubo yokunamathisela, ama-veneers ahlelwe ngendlela ye-crisscross ngokusho kwesiqondiso sokusanhlamvu kwezinkuni ukuze enze i-billet.

Ukucindezela Okubandayo Nokulungisa

I-Cold pressing, eyaziwa nangokuthi i-pre-pressing, isetshenziselwa ukwenza ama-veneers anamathele komunye nomunye, ukuvimbela amaphutha afana nokugudluka kwe-veneer kanye nokupakishwa kwebhodi okuyisisekelo ngesikhathi sokunyakaza nokuphatha, kuyilapho futhi kukhulisa ukuguquguquka kweglue ukuze kube lula ukwakheka kwefilimu yeglue enhle ebusweni be-veneers, ukugwema ukwenzeka kokuntuleka kweglue kanye neglue elomile.I-billet ihanjiswa emshinini wokucindezela ngaphambili futhi ngemva kwemizuzu engu-50 yokucindezela okubandayo okusheshayo, ibhodi eliyinhloko lenziwa.

Ukulungiswa kwe-billet yebhodi kuyinqubo eyengeziwe ngaphambi kokucindezela okushisayo.Abasebenzi balungisa ungqimba olungaphezulu lwebhodi eliwumgogodla ngongqimba ukuze baqinisekise ukuthi ubuso balo bushelelezi futhi buhle.

Ukucindezela Okushisayo Nokwelapha

Umshini wokucindezela oshisayo ungomunye wemishini ebaluleke kakhulu ekukhiqizeni i-plywood.Ukucindezela okushisayo kungagwema ngempumelelo izinkinga zokwakheka kwebhamuza kanye ne-delamination yendawo ku-plywood.Ngemuva kokucindezela okushisayo, i-billet idinga ukupholiswa cishe imizuzu engu-15 ukuqinisekisa ukuthi isakhiwo somkhiqizo sizinzile, amandla aphezulu, futhi ugweme ukuguqulwa kwe-warping.Le nqubo yilokho esikubiza ngokuthi "inkathi yokwelapha".

Ukusaha, ukuklwebha kanye nokusaha

Ngemuva kwesikhathi sokuphulukisa, i-billet izothunyelwa emshinini wokusika ukuze isikwe emibhalweni ehambisanayo namasayizi, ahambisanayo futhi ahlanzekile.Bese, ingaphezulu lebhodi liyakwalwa, lomiswe, futhi linenhlabathi ukuze kuqinisekiswe ukushelela okuphelele, ukuthungwa okucacile, nokucwebezela okuhle kwendawo yebhodi.Kuze kube manje, umzuliswano wokuqala wezinqubo zokukhiqiza eziyi-14 zenqubo yokukhiqiza i-plywood usuphothuliwe.

Ukucindezelwa kathathu, ukulungisa kathathu, ukusaha kathathu, nokusaha kathathu

I-plywood yekhwalithi ephezulu idinga ukudlula kuzinqubo eziningi zokupholisha ezinhle.Ngemuva kokugcotshwa kwesihlabathi kokuqala, i-plywood izofakwa okwesibili, ukucindezela okubandayo, ukukhanda, ukucindezelwa okushisayo, ukusaha, ukuklwebha, ukomiswa, ukuseshwa kwesihlabathi, nokukhuhlwa kwamabala, okuyingqikithi yezinqubo ezingu-9 emzuliswaneni wesibili.

Ekugcineni, i-billet inamathiselwe ngokhuni oluhle futhi oluhle lobuchwepheshe, i-mahogany surface, futhi i-plywood ngayinye iphinde idlule ekucindezeleni okubandayo okwesithathu, ukulungisa, ukucindezela okushisayo, ukuklwebula, ukusefa, ukusaha, nezinye izinqubo ezingu-9.Ingqikithi "yokucindezelwa okuthathu, ukulungiswa okuthathu, amasaha amathathu, ama-sanding amathathu" izinqubo zokukhiqiza ezingama-32, indawo yebhodi eyisicaba, ezinzile ngokwesakhiwo, inenani elincane lokuguqulwa, futhi yinhle futhi ihlala isikhathi eside iyakhiqizwa.

Ukugcwalisa, Ukuhlunga Komkhiqizo Okuphelile

I-plywood eyakhiwe iyahlolwa futhi igcwaliswe ngemva kokuhlolwa kokugcina bese ihlungwa.Ngokuhlolwa kwesayensi kogqinsi, ubude, ububanzi, umswakama, nekhwalithi yendawo, namanye amazinga, ukuze kuqinisekiswe ukuthi ipulangwe ngalinye elikhiqizwayo lisezingeni elifanele nelizinzile, elinomzimba kanye nokusebenza okuhle kakhulu kokucubungula.

Ukupakisha kanye Nesitoreji

Ngemva kokuba umkhiqizo osuphelile usukhethiwe, izisebenzi zipakisha ipulangwe endaweni yokugcina ukuze zigweme ilanga nemvula.

TONGLI TIMBER

Lapha, abakhiqizi be-plywood base-China bakukhumbuza ukuthi lapho uthenga i-plywood, kubalulekile ukuthola umkhiqizi womthombo ukuze uthole ukukhetha okuchwepheshile, okuphephile, nokongayo.

I-plywood isetshenziselwa ini?

I-plywood iwuhlobo olujwayelekile lwebhodi olusetshenziswa kuzo zonke izimboni ezahlukahlukene.Ahlukaniswa ngokwezigabai-plywood evamilefuthiplywood ekhethekile.

Ukusetshenziswa okuyinhloko kweplywood ekhethekilezimi kanje:

1.Ibanga lokuqala lilungele imihlobiso yezakhiwo ezisezingeni eliphezulu, ifenisha esezingeni eliphakathi kuya kwephezulu, namakesi ezinto ezisebenza ngogesi ezinhlobonhlobo.

2.Ibanga lesibili lifanele ifenisha, ukwakhiwa okujwayelekile, imoto, kanye nemihlobiso yemikhumbi.

3.Ibanga lesithathu lilungele ukulungiswa kwesakhiwo esisezingeni eliphansi kanye nezinto zokupakisha.Ibanga elikhethekile lifanele imihlobiso yezakhiwo ezisezingeni eliphezulu, ifenisha ephezulu, neminye imikhiqizo enezidingo ezikhethekile.

I-plywood evamileihlukaniswa yaba Ikilasi I, Ikilasi II, kanye Nekilasi III ngokusekelwe ekulimaleni kwezinto ezibonakalayo kanye nokukhubazeka kokucubungula ku-plywood ngemva kokucubungula.

1.I-Plywood yekilasi I: I-plywood ekwazi ukumelana nesimo sezulu, ehlala isikhathi eside futhi ekwazi ukumelana nokubilisa noma ukwelashwa ngesitimu, elungele ukusetshenziswa ngaphandle.

I-2.I-plywood ye-Class II: I-plywood engavimbeli amanzi, engacwiliswa emanzini abandayo noma ifakwe emanzini ashisayo isikhathi esifushane, kodwa ayifanele ukubiliswa.

3.I-plywood ye-Class III: I-plywood engazweli umswakama, ekwazi ukumelana nokucwiliswa kwamanzi abandayo isikhathi esifushane, ilungele ukusetshenziswa endlini.
