Senze nefanitshala eyenziwe ngezinye izinto ngaphandle kweenkuni, kubandakanywa iplywood kunye neebhodi zeminwe, kodwa ngoku senza kuphela i-plywood sisebenzisa ezi zinto zilandelayo: E0, E1, kunye ne-E2 zonke zibhekisela kwimigangatho yokusingqongileyo kunye namanqanaba alinganiselweyo okukhululwa kwe-formaldehyde.E2（≤ 5.0mg/L), E1 (≤1.5mg/L), E0 (≤0.5mg/L)
I-E1 iyimfuneko esisiseko kwiplywood yorhwebo ukuhlangabezana neemeko zokuhlala.Ngokunyuka kwemfuno yeemveliso,
Iiplanga eziqinileyo zokhuni olunemigangatho emininzi iplywood ziya zinyusa izinga lokukhuselwa kwendalo ukuya kwi-E0.
Indlela yokwahlula umgangatho weplywood, unokwahlulwa kwezi zinto zilandelayo:
Okokuqala, amandla okubopha alungile;Naluphi na uhlobo lwamandla okubambelela ebhodini lungcono, oku kuthetha ukuba i-adhesive force iyimfuneko.Okokuqala, jonga ukuba kukho isenzeko esicacileyo somaleko malunga nokuba kukho amaqamza ngaphezulu.Okwesibini, ngokutyhala ngesandla kunye nokucofa i-clamp, ngaba uyeva nayiphi na ingxolo.Ewe, ukuba kukho ingxolo, isenokungabangelwa kukunganyaniseki komgangatho wokuncamathelisa.Isenokuba ngenxa yesiseko esingenanto okanye izinto ezimbi ezisetyenziselwa ibhodi engundoqo, kodwa konke kubonisa ukuba umgangatho awulungile.
Okwesibini, ukuba flatness kulungile;Ukusuka kweli nqanaba, kunokubonwa ukuba kusetyenziswe izinto zangaphakathi zebhodi.Xa sijonge ibhodi, siyibamba ngezandla ukuze sive ukuba kukho ukungalingani.Ukuba kukho nayiphi na, ibonisa iingongoma ezimbini: mhlawumbi umphezulu awukho isanti kakuhle, okanye ibhodi engundoqo yenziwe ngezinto ezihluphekileyo, eziqhekezayo.
Okwesithathu, Xa ibhodi ijiyile, kulula ukuyibona.Ngokomzekelo, i-plywood ye-18cm ye-multi-layer yenziwe ngokucinezela i-11 yebhodi engundoqo.Ukuba umaleko ngamnye wenziwe ngezinto ezipheleleyo, iileyile zicace kakhulu kwaye aziyi kubakho ziganeko zokugqithelana.Ukuba izinto azisetyenziswanga kakuhle kwaye zininzi izinto ezichotshoziweyo, ngenxa yoxinzelelo, iileyile ziya kukhwelana kwaye zenze ukungalingani komhlaba.
Okwesine, ibhodi elungileyo ayiguquki;Iqondo lokuguqulwa linxulumene ikakhulu neempawu ezibonakalayo zomthi ngokwawo, umxholo wokufuma, kunye nemozulu.Into esinokuyilawula sisiqulatho sokufuma.Sinokukhetha kwakhona ukhuni olune-deformation encinci.
Okwesihlanu, nokuba ubungqingqwa bungaphakathi koluhlu olusemgangathweni;Ngokuqhelekileyo, ubukhulu beebhodi ezilungileyo buphakathi koluhlu lwemigangatho yelizwe.
Umphambili webhodi yeminwe iyafana naleyo yeplywood ye-multi-layer.Ibhodi yeminwe yibhodi eyenziwe ngokudibanisa inkunkuma eshiyekileyo emva kokucubungula iinkuni ezikrwada, kwaye ibhodi ye-multi-layer yibhodi enqumla ibhodi yoqobo yamaplanga ibe ngamaqhekeza amancinci ize iwadibanise.Amaxabiso ezi zimbini ziyafana, kodwa ngenxa yokunqongophala kokubekwa kwibhodi yeminwe, ixhomekeke ngakumbi kwi-deformation xa kuthelekiswa ne-plywood ye-multi-layer.
Ukusebenziseka kweepleyiti ezidityanisiweyo zeminwe azikho banzi njengaleyo yeepleyiti zamaleko amaninzi.Umzekelo, ukuba amanye amacandelo amade asetyenziswa kunye neepleyiti ezidityanisiweyo zeminwe, umthamo wazo wokuthwala umthwalo awulunganga njengalowo weplywood yomaleko amaninzi, kwaye athanda ukuqhekeka phantsi komgangatho othile wamandla angaphandle.Iibhodi zeminwe zisetyenziselwa ukwenza iipaneli ezinkulu zeengcango kunye namashalofu.Kwaye ezi plywood zinamaleko amaninzi zisenokwenziwa, ngoko asifane sisebenzise iibhodi ezidityanisiweyo zeminwe ngoku.
