Intshayelelo kwiplywood.

I-Plywood yibhodi enemigangatho emithathu okanye i-multi-layer-efana nebhodi eyenziwe ngamacandelwana emithi axotyulwe kwi-veneers okanye anqunyulwe kumthi obhityileyo, emva koko ancamathiselwe ngeglu.Ngokuqhelekileyo, kusetyenziswa ii-veneers ezinamanani angaqhelekanga, kwaye iileya ezikufutshane ze-veneers zisetyenziswa.Izalathiso zefiber zincanyathiselwe kwi-perpendicular enye kwenye.

IPlywood yenye yezinto ezisetyenziswa ngokuqhelekileyo kwifanitshala, kwaye yenye yeebhodi ezintathu eziphambili zeepaneli ezenziwe ngamaplanga.Ingasetyenziselwa iinqwelomoya, iinqanawa, oololiwe, iimoto, izakhiwo kunye neebhokisi zokupakisha.Iqela le-veneers lidla ngokudityaniswa kwaye lidityaniswe ngokuhambelana necala leenkozo zokhuni zomaleko ezimeleneyo ezihambelanayo.Ngokwesiqhelo, ibhodi yomphezulu kunye nebhodi yomaleko yangaphakathi icwangciswe ngokulinganayo kumacala omabini omgangatho weziko okanye umbindi.I-slab eyenziwe nge-veneer emva kwe-gluing i-criss-inqunyulwe ngokwendlela yengqolowa yokhuni, kwaye icinezelwe phantsi kweemeko ezifudumalayo okanye ezingenakufudumala.Inani leeleya lidla ngokuba linani elingumnqakathi, kwaye abambalwa banamanani alinganayo.Umahluko kwiipropati ezibonakalayo kunye noomatshini kwiindlela ezithe nkqo nezithe tye zincinci.Iindidi ezisetyenziswa ngokuqhelekileyo zeplywood zibhodi ezintathu, ibhodi ezintlanu kunye nokunye.I-Plywood inokuphucula ukusetyenziswa kweenkuni kwaye iyindlela enkulu yokugcina iinkuni.

Ukuze kuphuculwe iimpawu ze-anisotropic zomthi wendalo kangangoko kunokwenzeka, ukwenzela ukuba iipropati zeplywood zifanane kwaye umzobo uzinzile, isakhiwo seplywood jikelele kufuneka sihambisane nemigaqo emibini esisiseko: enye i-symmetry;enye yeyokuba iintsinga zomaleko okufutshane we-veneer zi-perpendicular omnye komnye.Umgaqo we-symmetry kukufuna ukuba i-veneers kumacala omabini e-symmetrical central plane yeplywood kufuneka ibe yi-symmetrical enye kwenye kungakhathaliseki ukuba luhlobo luni lomthi, ubukhulu be-veneer, inani leemaleko, isalathiso somgca. imicu, kunye nomxholo wokufuma.Kwi-plywood efanayo, i-veneers yohlobo olulodwa kunye nobukhulu bunokusetyenziswa, okanye i-veneers yeentlobo ezahlukeneyo kunye nobukhulu bunokusetyenziswa;nangona kunjalo, naziphi na iileya ezimbini zeveneers ezilinganayo enye kwenye kumacala omabini e-symmetrical central plane kufuneka ibe neentlobo ezifanayo kunye nobukhulu.Iiphaneli zobuso kunye nomqolo azivumelekanga ukuba zibe zodidi lwemithi efanayo.

Ukwenza ulwakhiwo lweplywood luhlangabezane nemigaqo emibini esisiseko ngexesha elinye, inani lalo lemigangatho kufuneka libe lingaqhelekanga.Ngoko ke, i-plywood idla ngokwenziwa ibe ngamaleko angama-odd-numbered likes three, five layers, and seven layers.Amagama oluhlu ngalunye lweplywood ngala: i-surface veneer ibizwa ngokuba yi-surface board, i-internal veneer ibizwa ngokuba yi-core board;ibhodi yangaphambili ibizwa ngokuba yiphaneli, kwaye ibhodi yangasemva ibizwa ngokuba yibhodi yangasemva;kwibhodi engundoqo, ulwalathiso lwefiber luhambelana nebhodi Ibizwa ngokuba yibhodi engundoqo ende okanye ibhodi ephakathi.Xa usenza i-cavity deck slabs, iipaneli zangaphambili nasemva kufuneka zijongane ngokuqinileyo ngaphandle.
