Plywood ndi bolodi la magawo atatu kapena angapo osanjikiza ngati zinthu zopangidwa pozungulira ndikudula zigawo zamatabwa kukhala matabwa kapena matabwa kukhala matabwa owonda, kenako kumangiriza ndi zomatira.Nthawi zambiri amapangidwa ndi mikwingwirima yosamvetseka, ndipo mayendedwe a ulusi wa zigawo zoyandikana za veneer amakhala perpendicular kwa wina ndi mzake.
Plywood ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pamipando, imodzi mwamapulogalamu akuluakulu atatu opangira, ndipo imatha kugwiritsidwanso ntchito ngati zida zandege, zombo, masitima apamtunda, magalimoto, nyumba, ndi mabokosi onyamula.Gulu la veneers zambiri aumbike ndi gluing moyandikana zigawo za matabwa tirigu perpendicular mzake, ndi pamwamba ndi mkati zigawo symmetrically anakonza mbali zonse za chapakati wosanjikiza kapena pachimake.Chovala chopangidwa polumikizira cholumikizira chomata polowera kunjere ndikukanikizira potenthetsa kapena osatenthetsa.Chiwerengero cha zigawo nthawi zambiri chimakhala chosamvetseka, ndipo ochepa amatha kukhala ndi manambala ofanana.Kusiyana kwa thupi ndi makina azinthu zowongoka ndi zopingasa ndizochepa.Plywood imatha kupititsa patsogolo kugwiritsa ntchito nkhuni ndipo ndi njira yayikulu yopulumutsira nkhuni.
Matchulidwe a plywood ndi: 1220 × 2440mm, pomwe makulidwe ake amaphatikiza: 3, 5, 9, 12, 15, 18mm, ndi zina. Mitundu yayikulu yamitengo imaphatikizapo beech, camphor, msondodzi, popula, bulugamu, birch, etc.

Mfundo Yoyambira
Pofuna kupititsa patsogolo mphamvu ya anisotropic ya matabwa achilengedwe momwe mungathere, ndikupanga mawonekedwe a plywood yunifolomu ndi mawonekedwe okhazikika, mapangidwe a plywood nthawi zambiri amatsatira mfundo ziwiri zofunika: choyamba, symmetry;Chachiwiri ndi chakuti zigawo zoyandikana za ulusi wa veneer ndi perpendicular kwa wina ndi mzake.Mfundo ya symmetry amafuna kuti veneer mbali zonse za symmetrical chapakati ndege plywood, mosasamala kanthu za matabwa katundu, veneer makulidwe, chiwerengero cha zigawo, CHIKWANGWANI malangizo, chinyezi, etc., ayenera symmetrical wina ndi mzake.Mu plywood yomweyo, mitundu ya mtengo umodzi ndi makulidwe a veneer angagwiritsidwe ntchito, komanso mitundu yosiyanasiyana ya mitengo ndi makulidwe a veneer;Koma zigawo ziwiri zilizonse zamitengo yofanana mbali zonse za symmetrical yapakati ndege iyenera kukhala yokhuthala mofanana.Zapamwamba ndi zam'mbuyo zimaloledwa kukhala zamitundu yosiyanasiyana yamitengo.
Kuonetsetsa kuti mapangidwe a plywood akugwirizana ndi mfundo zonse zomwe zili pamwambazi, chiwerengero chake cha zigawo chiyenera kukhala chosamvetseka.Choncho plywood nthawi zambiri imapangidwa kukhala zigawo zitatu, zigawo zisanu, zisanu ndi ziwiri, ndi zina zosamvetseka.Mayina a gulu lirilonse la plywood ndi: pamwamba pa veneer amatchedwa pamwamba bolodi, ndipo mkati mwa veneer amatchedwa core board;Gulu lakutsogolo limatchedwa gulu, ndipo gulu lakumbuyo limatchedwa gulu lakumbuyo;Pakatikati pa bolodi, mawonekedwe a ulusi wofanana ndi gulu lapamwamba amatchedwa bolodi lalitali kapena bolodi lapakati.Popanga slab ya tebulo, gululi ndi gulu lakumbuyo liyenera kuyang'ana kunja mwamphamvu.
