I-1) I-plywood ye-veneer yokuhlobisa ibhodi elenziwe ngabantu elenziwe nge-veneer yokuhlobisa yokhuni yemvelo enamathiselwe ku-plywood.I-decorative veneer iwukhuni oluncanyana olwenziwe ngokhuni lwekhwalithi ephezulu ngokusebenzisa i-planing noma ukusika okujikelezayo
2) Izici ze-plywood ye-veneer yokuhlobisa:
I-plywood ye-veneer yokuhlobisa ingenye yezinto ezisetshenziswa kakhulu zokuhlobisa kwangaphakathi.Ngenxa yokuthi i-veneer yokuhlobisa ebusweni balo mkhiqizo yenziwe ngezinkuni ezisezingeni eliphezulu ngokusebenzisa i-planing noma i-rotary cutting, inomsebenzi wokuhlobisa ongcono kune-plywood.Lo mkhiqizo ulula ngokwemvelo, wemvelo futhi uhloniphekile, futhi ungakha indawo yokuhlala enhle enobudlelwane obuhle kakhulu babantu.
3) Izinhlobo ze-plywood ye-veneer yokuhlobisa:
I-veneer yokuhlobisa ingahlukaniswa ibe yi-veneer yokuhlobisa ehlangothini olulodwa kanye ne-double-sided veneer yokuhlobisa ngokusho kwendawo yokuhlobisa;Ngokusho kokumelana kwayo namanzi, ingahlukaniswa nge-plywood ye-veneer yokuhlobisa ye-Class I, i-plywood ye-veneer yokuhlobisa ye-Class II, kanye ne-Class III yokuhlobisa i-veneer plywood;Ngokusho kokuthungwa kwe-veneer yokuhlobisa, ingahlukaniswa ibe yi-radial yokuhlobisa i-veneer kanye ne-chord yokuhlobisa i-veneer.Okuvamile i-plywood ye-veneer yokuhlobisa ehlangothini olulodwa.Izinhlobo zokhuni ezivame ukusetshenziselwa ama-veneers okuhlobisa zihlanganisa i-birch, umlotha, i-oki, i-elm, i-maple, i-walnut, njll.
4) Ukuhlukaniswa kwe-plywood ye-veneer yokuhlobisa:
Izinga le-plywood ye-veneer yokuhlobisa e-China ibeka ukuthi i-plywood ye-veneer yokuhlobisa ihlukaniswe ngamaleveli amathathu: Imikhiqizo ephezulu, imikhiqizo yezinga lokuqala kanye nemikhiqizo efanelekayo.Lokhu kukhumbuza abakhiqizi nabathengi ukuthi ezinye izinhlobo zokugreda azihambisani nezindinganiso zaseShayina ze-plywood ye-veneer yokuhlobisa.Isibonelo, abanye abakhiqizi banezinga lelebula elithi "AAA", okuwukuziphatha kwenkampani.
5) Izidingo zokusebenza zamazinga kazwelonke we-plywood ye-veneer yokuhlobisa: Izinga elinconyiwe lamanje e-China yi-GB/T 15104-2006 "Ibhodi lokufakelwa le-Decorative veneer", elisetshenziswa iningi lamabhizinisi ekukhiqizeni.Leli zinga licacisa izinkomba ze-plywood ye-veneer yokuhlobisa ngokuya ngekhwalithi yokubukeka, ukunemba kokucubungula, kanye nezakhiwo zomzimba nezomshini.Izinkomba zayo zokusebenza ngokomzimba nangokwemishini zihlanganisa umswakama, amandla okubopha phezulu, nokuxebuka kokucwiliswa.I-GB 18580-2001 "Imikhawulo Yokuphuma Kwe-Formaldehyde Yezinto Zokuhlobisa Ngaphakathi, Amaphaneli Okwenziwa Nemikhiqizo Yawo" iphinda icacise izinkomba zomkhawulo wokukhishwa kwe-formaldehyde zalo mkhiqizo.
① Izinga likazwelonke libeka ukuthi inkomba yokuqukethwe komswakama we-plywood ye-veneer yokuhlobisa ingu-6% kuya ku-14%.
② Amandla okubopha phezulu abonisa amandla okubopha phakathi kongqimba lwe-veneer yokuhlobisa kanye ne-plywood substrate.Izinga likazwelonke libeka ukuthi le nkomba kufanele ibe ngu-≥ 50MPa, futhi inani lezingcezu zokuhlola eziqeqeshiwe kufanele libe ngu-≥ 80%.Uma le nkomba ingafanelekile, ibonisa ukuthi ikhwalithi yokubopha phakathi kwe-veneer yokuhlobisa kanye ne-substrate plywood impofu, engabangela ungqimba lwe-veneer yokuhlobisa ukuba luvuleke futhi luqhume ngesikhathi sokusetshenziswa.
③ Ukucwecwa kokukhulelwa kubonisa ukusebenza kokubopha kwesendlalelo ngasinye seplywood yevene yokuhlobisa.Uma le nkomba ingafanelekile, ibonisa ukuthi ikhwalithi yokubopha ibhodi impofu, engabangela ukuvulwa kokunamathela ngesikhathi sokusetshenziswa.
④ Umkhawulo wokukhishwa kwe-formaldehyde.Le nkomba iyindinganiso kazwelonke eyimpoqo eyasetshenziswa yiShayina ngoJanuwari 1, 2002, "okuyimvume yokukhiqiza" yemikhiqizo ehlobene.Imikhiqizo engahlangabezani naleli zinga ayivunyelwe ukukhiqizwa kusukela ngomhlaka-1 Januwari 2002;Lesi futhi "isitifiketi sokufinyelela emakethe" semikhiqizo ehlobene, futhi imikhiqizo engahlangabezani naleli zinga ayivunyelwe ukungena emkhakheni wokusakazwa kwemakethe kusukela ngomhlaka-1 Julayi, 2002. Ukweqa umkhawulo we-formaldehyde kuzothinta impilo engokomzimba yabathengi.Izinga libeka ukuthi ukukhishwa kwe-formaldehyde yeplywood ye-veneer veneer yokuhlobisa kufanele kufinyelele:E0level : ≤0.5mg/L, ileveli E1 ≤ 1.5mg/L, ileveli E2 ≤ 5.0mg/L.
Ukukhetha
Ekukhiqizeni i-plywood, kuye kwatholakala izinhlobo eziningi zemiklamo nemibala, phakathi kwazo okubaluleke kakhulu ukunamathisela ungqimba oluncane lwe-veneer yokuhlobisa ebusweni be-plywood yasekuqaleni, eyaziwa ngokuthi i-plywood ye-veneer yokuhlobisa, efushanisiwe njengebhodi lokuhlobisa noma iphaneli yokuhlobisa emakethe.
Kuyaqapheleka ukuthi amaphaneli okuhlobisa ajwayelekile ahlukaniswe ngamaphaneli okuhlobisa okhuni lwemvelo kanye namaphaneli okuhlobisa amapulangwe amancane.I-natural wood veneer i-veneer encane eyenziwe ngokhuni lwemvelo oluyigugu ngokusebenzisa i-planing noma i-rotary cutting processing.I-Artificial Veneer iyivene yokuhlobisa eyenziwe ngokhuni olungavuthiwe olushibhile, oluphothwayo bese lunqunywa lube izikwele zokhuni ngenqubo ethile yokunamathisela nokucindezela.Bese ihlelwa futhi isikwe ibe yi-veneer yokuhlobisa ngamaphethini amahle.
Ngokuvamile, amapulangwe emvelo ahlotshiswe ngezingubo zokuhlobisa ezinamaphethini amahle nenani eliphakeme, njenge-cypress, i-oki, i-rosewood, nomlotha.Kodwa-ke, kufanele icaciswe egameni lomkhiqizo, njengokuthi "i-cypress veneer plywood", "i-plywood yamanzi eqoshiwe", noma "i-cherry wood veneer".Izici eziyisisekelo "zebhodi lokuhlobisa" zibonakala ngezindlela eziningana zokuqamba amagama njenge "veneer", "slicing", kanye "nebhodi lokuhlobisa".Kodwa-ke, ayikwazi ukufushaniswa njenge-cypress plywood noma i-water ash plywood, njengoba lezi zifinyezo zibhekisela kumapaneli e-plywood namapuleti aphansi enziwe nge-cypress noma umlotha wamanzi.Enye inkinga ukuthi ukukhiqizwa kwefenisha ngamapaneli okuhlobisa kuyanda.Nakuba le fenisha ingase ibe nokubukeka "kokhuni lomsayiphuresi" noma ezinye izinhlamvu zokhuni, ukhuni oluphelele olusetshenziselwa ifenisha lwenziwa ngezinye izinkuni.Namuhla, izitolo zilebula le fenisha ngokuthi “
Amaphuzu abalulekile okukhetha
1) Khetha izinhlobo ezahlukene, amabanga, izinto zokwakha, imihlobiso, nosayizi beplywood ngokusekelwe ezintweni ezifana nezakhiwo zobunjiniyela, izindawo zokusetshenziswa, nezimo zemvelo.
2) Umhlobiso kufanele usebenzise izinkuni eziyigugu ezine-veneer encane
3) I-plywood esetshenziselwa ukuhlobisa kwangaphakathi kwezakhiwo kufanele ihambisane nezinhlinzeko ze-GB50222 "Ikhodi Yokuvikela Umlilo Yomklamo Wokuhlobisa Kwangaphakathi Kwezakhiwo"
4) Izingxenye ezifihliwe ezingase zithintwe umswakama kanye nezikhathi ezinezidingo eziphakeme zokungangeni kwamanzi kufanele zicabange ukusebenzisa i-plywood Yekilasi I noma Yekilasi II, futhi i-plywood Yekilasi I kufanele isetshenziselwe ukusetshenziswa ngaphandle.
I-5) Ukuhlobisa kwephaneli kudinga ukusetshenziswa kwe-varnish ebonakalayo (eyaziwa nangokuthi i-varnish) ukuze kugcinwe umbala wemvelo nokuthungwa kwendawo yokhuni.Kumelwe kugcizelelwe ekukhethweni kwezinto zamaphaneli, amaphethini, nemibala;Uma iphethini nombala wephaneli kungadingeki kucatshangelwe, ibanga nesigaba se-plywood kufanele futhi kukhethwe ngokunengqondo ngokusekelwe endaweni kanye nezindleko.
