I-plywood iwuhlobo lwebhodi lezinkuni elenziwe umuntu elihlanganiswa kabusha ngokucwecwa.
I-Plywood yenziwe ngokusikwa ibe yi-veneers yendawo enkulu ekuqondeni izindandatho zonyaka. Ngemuva kokumisa nokubopha, kukhiqizwa ngokwezinga lokuma kwezinhlamvu ze-mahogany eziqondile zama-veneers aseduze.
Inombolo yamabhodi ayisisekelo ngokuvamile iyinani eliyinqaba lezendlalelo, ngokuvamile izingqimba ezintathu kuya kweziyishumi nantathu, futhi inani elivamile lezendlalelo ngokuvamile liyizendlalelo ezintathu, izingqimba ezinhlanu, izendlalelo eziyisishiyagalolunye, nezingqimba eziyi-13 (imakethe yokuthengisa ngokuvamile ibizwa ngokuthi ngamapulangwe amathathu, amahlanu. ipulangwe, ipulangwe eyisishiyagalolunye, amasentimitha ayishumi nantathu). I-veneer yangaphambili yongqimba olungaphandle kakhulu ibizwa ngokuthi i-front panel, ingemuva ibizwa ngokuthi i-back panel, kanti ungqimba lwangaphakathi lubizwa ngokuthi ibhodi eliyinhloko.
I-plywood yohlobo loku-1 inezinzuzo zokumelana nesimo sezulu, ukumelana namanzi abilayo, ukuqina, ukumelana nezinga lokushisa eliphezulu, nokumelana nomusi.
Lezi zinhlobo ezi-2 ze-plywood ziyi-plywood engenamanzi, engacwiliswa emanzini abandayo namanzi ashisayo ngesikhathi esifushane.
I-plywood yohlobo lwe-3 i-plywood engenawo amanzi, engacwiliswa emanzini abandayo isikhathi esifushane, efanelekile ekushiseni kwangaphakathi ekamelweni. Ifenisha kanye nezinjongo zokwakha jikelele;
I-plywood yohlobo 4 iyi-plywood engazweli umswakama, evame ukusetshenziswa endlini. I-plywood evame ukusetshenziswa ihlanganisa i-birch, i-eucalyptus, ne-poplar.
I-plywood isetshenziswa kakhulu ezimweni zangaphandle, njengokwakha umhlobiso wangaphandle kanye nefomu lekhonkolo. Ekuhlobiseni, isetshenziswa ikakhulukazi ophahleni, iziketi zodonga, nama-floor liners.
Ukwakheka okuyisisekelo kweplywood
Ukuze uthuthukise i-anisotropy yokhuni lwemvelo ngangokunokwenzeka, i-plywood inezici ezifanayo kanye nesimo esizinzile. Ngokuvamile, i-plywood kufanele ilandele izimiso ezimbili eziyisisekelo esakhiweni: eyodwa i-symmetrical; enye iwukuthi imicu ye-optical yebhodi elilodwa eseduze incikene.
Umgomo wokulinganisa ukuthi i-plywood iyadingeka ezinhlangothini zombili zendiza ephakathi ye-symmetry ye-plywood, kungakhathaliseki ukuthi imvelo yokhuni, ubukhulu be-plywood, inani lezendlalelo, isiqondiso se-fiber, kanye nomswakama. okuqukethwe kufanele kulingane komunye nomunye.
Ku-plywood efanayo, izihlahla ezilodwa kanye nama-veneers of thick zingasetshenziswa, noma ama-veneers ezinhlobo ezahlukene zezihlahla nokuqina kungasetshenziswa; Nokho, noma yiziphi izingqimba ezimbili zezihlahla ze-veneer ezilinganayo kanye nogqinsi ezinhlangothini zombili zendiza ephakathi nendawo ziyefana.
Ukuze wenze isakhiwo se-plywood sihlangabezane nezimiso ezimbili eziyisisekelo ezingenhla, inani lezendlalelo kufanele libe yinqaba.
Ngakho-ke, i-plywood ivame ukuhlukaniswa zibe izingqimba ezintathu, izingqimba ezinhlanu, izendlalelo eziyisikhombisa nezinye izingqimba ezingavamile.
Igama le-plywood layer lithi: i-surface veneer ibizwa ngokuthi itafula, i-veneer yangaphakathi ibizwa ngokuthi ibhodi eliyinhloko; iphaneli yangaphambili ibizwa ngokuthi iphaneli, futhi iphaneli yangemuva ibizwa ngokuthi iphaneli yangemuva; ebhodini eliyinhloko, isiqondiso se-fiber sihambisana nephaneli.
Ibizwa ngokuthi ibhodi eliwumgogodla omude noma ibhodi eliphakathi.
Izinzuzo zeplywood
Izinzuzo ze-plywood zinamandla okuthwala, akulula ukukhubaza nokugoba, akulula ukuqhekeka, nokunwetshwa okuncane. Ibhodi le-Multilayer linekhono elihle lokuzivumelanisa nezinga lokushisa langaphakathi kanye nomswakama. Isendlalelo esingaphezulu sebhodi le-multilayer yizinkuni zemvelo. Izinhlamvu zokhuni ziseduze nemvelo futhi ifomethi inkulu. Izinzuzo zamabhodi anezingqimba eziningi kulula ukukhanda. Uma kuqhathaniswa nokhuni oluqinile lwelogi, ibhodi elinezingqimba eziningi ligwema ezinye iziphambeko zemvelo zokhuni lwemvelo, njengokungingiza, ububanzi, ukuwohloka, kanye nokumelana nokucindezelwa okubi.
Amabhodi e-Multi-layer nawo anenzuzo enkulu ngaphezu kwezinkuni zemvelo ngentengo. Njengoba amabhodi anezingqimba eziningi ehlaziya futhi futhi ahlele kabusha izingodo, ayonga kakhulu kunamabhodi ogodo aqinile abizayo.
Ukungalungi kwebhodi le-multilayer
Ibhodi elinezingqimba eziningi lenziwe ngebhodi lesisekelo sokhuni lwemvelo ngokusebenzisa izinga lokushisa eliphezulu kanye nokucindezela okuphezulu emshinini wokushisa oshisayo nge-adhesive. Ngakho-ke, mayelana nokuvikelwa kwemvelo, kuzoba nokukhululwa okuthile kwe-formaldehyde. Kodwa iseduze kakhulu nokhuni lwemvelo futhi iphinde ibe ibhodi yokwenziwa enobungani kakhulu nemvelo.
Ukuhlonza i-plywood enhle noma embi
Okokuqala, bheka ukukhanya kwephaneli. Kusukela kuleli phuzu, singabona izinto zangaphakathi zebhodi. Uma sibheka ibhodi, singalithinta ngezandla zethu futhi sizwe ukuthi akukho yini ukungalingani. Uma kukhona, kusho ukuthi ukugcotshwa kwesihlabathi akukuhle.
Kuphakathi kokuthi kusho ukuthi impahla yebhodi ewumgogodla ayilungile futhi impahla iphukile ngokuqhathaniswa. Ngamafuphi, akunconywa ukuthenga okungalingani.
Okwesibili, bheka umuzwa wokulandelana kwebhodi lezingqimba eziningi. Uma ibhodi lijiyile, kuba lula ukubona uhlaka lwebhodi elinezingqimba eziningi. Uma ungqimba ngalunye lwenziwe ngezinto ezibonakalayo ze-monolithic, izendlalelo zizocaca kakhulu futhi ngeke kube khona ukwenzeka kwe-cross-layer. Uma impahla ingeyinhle, kunezinsalela eziningi.
Ngenxa yomphumela wengcindezi, izinga lizoba libi kakhulu ngemva kokucindezelana.
