I-Plywood luhlobo lwebhodi eyenziwe ngumntu edityaniswe ngokutsha ngokuxobula.
I-Plywood yenziwe ngokusikwa kwii-veneers zendawo enkulu kwicala leendandatho zonyaka. Emva kokumisa kunye nokudibanisa, kuveliswa ngokomgangatho we-vertical mahogany grain orientation of veneers ezikufutshane.
Inani leebhodi ezingundoqo ngokuqhelekileyo linani elingaqhelekanga leeleya, ngokwesiqhelo iileya ezintathu ukuya kwishumi elinesithathu, kwaye inani eliqhelekileyo lomaleko lidla ngokuba ziimaleko ezintathu, iileya ezintlanu, iileya ezilithoba, kunye neeleya ezili-13 (imarike yokuthengisa ibizwa ngokuba ngamaplanga amathathu, amahlanu. i-plywood, i-plywood elithoba, ishumi elinesithathu leesentimitha). Iveneer yangaphambili yomaleko ongaphandle ibizwa ngokuba yiphaneli yangaphambili, umva ubizwa ngokuba yipaneli yangasemva, kwaye umaleko ongaphakathi ubizwa ngokuba yibhodi engundoqo.
Uhlobo loku-1 lweplywood lunoncedo lokumelana nemozulu, ukumelana namanzi abilayo, ukuqina, ukumelana nobushushu obuphezulu, kunye nokumelana nomphunga.
Ezi ntlobo ze-2 zeplywood ziyi-plywood engenamanzi, enokuthi ifakwe emanzini abandayo kunye namanzi ashushu ngexesha elifutshane.
Uhlobo lwe-3 ye-plywood yi-plywood engenamanzi, enokuthi ifakwe emanzini abandayo ixesha elifutshane, elifanele ukushisa kwangaphakathi kwigumbi. Ifenitshala kunye neenjongo zokwakha jikelele;
Uhlobo lwe-4 ye-plywood yi-plywood enganyangekiyo ukufuma, edla ngokusetyenziswa ngaphakathi endlini. I-plywood esetyenziswa ngokuqhelekileyo iquka i-birch, i-eucalyptus, kunye ne-poplar.
I-Plywood isetyenziswa kakhulu kwiimeko zangaphandle, ezifana nokwakhiwa komhombiso wangaphandle kunye ne-formwork yekhonkrithi. Ekuhombiseni, isetyenziswa ikakhulu kwiisilingi, iziketi eludongeni, kunye ne-floor liners.
Ukubunjwa okusisiseko kweplywood
Ukuze kuphuculwe i-anisotropy yomthi wendalo kangangoko kunokwenzeka, i-plywood ineempawu ezifanayo kunye nesimo esizinzile. Ngokuqhelekileyo, i-plywood kufuneka ilandele imigaqo emibini esisiseko kwisakhiwo: enye i-symmetrical; enye yeyokuba imicu ye-optical fibers ekufutshane yebhodi enye i-perpendicular enye kwenye.
Umgaqo we-symmetry kukuba i-plywood iyadingeka kumacala omabini eplani ephakathi ye-symmetry ye-plywood, kungakhathaliseki ukuba luhlobo luni lomthi, ubukhulu beplali, inani leeleya, icala le-fiber kunye nokufuma. umxholo kufuneka ulingane omnye komnye.
Kwiplywood enye, imithi enye kunye ne-veneers of thickness inokusetyenziswa, okanye i-veneers yeentlobo ezahlukeneyo zemithi kunye nobukhulu bunokusetyenziswa; nangona kunjalo, naziphi iileyi ezimbini zemithi ye-veneer elinganayo kunye nobukhulu kumacala omabini we-symmetry center plane ziyafana.
Ukuze wenze isakhiwo seplywood sihlangabezane nale migaqo mibini ingasentla, inani leengqimba kufuneka libe lingaqhelekanga.
Ngoko ke, i-plywood idla ngokwahlulahlula ibe ngamanqwanqwa amathathu, iileya ezintlanu, iileya ezisixhenxe kunye nezinye iileya ezingaqhelekanga.
Igama le-plywood layer yile: i-surface veneer ibizwa ngokuba yitafile, i-internal veneer ibizwa ngokuba yibhodi engundoqo; iphaneli yangaphambili ibizwa ngokuba yiphaneli, kwaye ipaneli yangasemva ibizwa ngokuba yiphaneli yangasemva; kwibhodi engundoqo, ulwalathiso lwefiber luhambelana nephaneli.
Ibizwa ngokuba yibhodi engundoqo ende okanye ibhodi ephakathi.
Izinto eziluncedo zeplywood
Iinzuzo zeplywood zinamandla okuthwala amandla, akulula ukukhubaza kunye nokugoba, akulula ukuqhekeza, kunye nokwandiswa okuncinci. Ibhodi ye-Multilayer inekhono elihle lokuziqhelanisa nokushisa kwangaphakathi kunye nomswakama. Umphezulu webhodi ye-multilayer yimithi yendalo. Ingqolowa yokhuni isondele kwindalo kwaye ifomathi inkulu. Iingenelo zeebhodi ezinamanqwanqwa amaninzi kulula ukuzilungisa. Xa kuthelekiswa neplanga eliqinileyo leplanga, ibhodi enamaleko amaninzi inqanda ezinye iziphene zendalo zomthi wendalo, njengokuthintitha, ububanzi, ukonakala, kunye nokunganyangeki kakuhle.
Iibhodi ze-Multi-layer nazo zinenzuzo enkulu ngaphezu komthi wendalo kwixabiso. Ekubeni iibhodi ezinamanqwanqwa amaninzi zihlalutya kwakhona kwaye zilungelelanise iilogi, zinoqoqosho ngakumbi kuneebhodi zeplanga eziqinileyo zomthi.
Ukungalungi kwebhodi ye-multilayer
Ibhodi ye-multi-layer yenziwe ngebhodi engundoqo yomthi wendalo ngokusebenzisa ukushisa okuphezulu kunye noxinzelelo oluphezulu kwi-press eshushu kunye ne-adhesive. Ngoko ke, malunga nokukhuselwa kwendalo, kuya kubakho ukukhululwa kwe-formaldehyde. Kodwa ikufutshane kakhulu kumthi wendalo kwaye ikwayeyona bhodi yokwenziwa ehambelana nokusingqongileyo.
Ukuchongwa kweplywood elungileyo okanye embi
Okokuqala, jonga ukuthambeka kwephaneli. Ukusuka kweli nqanaba, sinokubona izinto zangaphakathi zebhodi. Xa sijonga ibhodi, sinokuyibamba ngezandla zethu kwaye sive ukuba kukho ukungalingani. Ukuba kukho, oko kuthetha ukuba i-sanding engaphezulu ayilungile.
Okanye kuthetha ukuba izinto zebhodi ezingundoqo azilungile kwaye izinto eziphathekayo zaphukile. Ngamafutshane, akukhuthazwa ukuthenga ukungalingani.
Okwesibini, jonga ingqiqo yolawulo lwebhodi ye-multilayer. Okukhona ibhodi ijiyile, kokukhona kulula ukubona umaleko webhodi enamaleko amaninzi. Ukuba uluhlu ngalunye lwenziwe ngezinto eziphathekayo ze-monolithic, iileyile ziya kucaca kakhulu kwaye aziyi kubakho i-cross-layer phenomenon. Ukuba imathiriyeli ayilungile, zininzi izinto ezilahliweyo.
Ngenxa yempembelelo yoxinzelelo, inqanaba liya kuba libi kakhulu emva kokuxinana.
