1. Plywood imagawidwa m'magulu atatu kapena kuposerapo a nkhuni zopyapyala ndi zomatira. Mitengo yambiri yopyapyala yomwe imapangidwa masiku ano ndi yopota yopyapyala, yomwe nthawi zambiri imatchedwa veneer. Ma veneers osawerengeka nthawi zambiri amagwiritsidwa ntchito. Mayendedwe a ulusi wa ma veneers oyandikana ali ndi perpendicular kwa wina ndi mnzake. Ma plywood atatu, plywood asanu, ma plywood asanu ndi awiri ndi zina zosawerengeka zomwe zimagwiritsidwa ntchito nthawi zambiri. Veneer yakunja kwambiri imatchedwa veneer, kutsogolo kwake amatchedwa panel, reverse veneer amatchedwa back plate, ndipo mkati mwake amatchedwa core plate kapena middle plate.
2. Mitundu ya plywood panel ndi mitundu ya plywood. Ku China, mitengo yomwe imagwiritsidwa ntchito kwambiri ndi basswood, Fraxinus mandshurica, birch, poplar, elm, mapulo, nkhuni zamtundu, Huangbo, mapulo, nanmu, Schima superba, ndi nkhandwe zaku China. Mitengo ya coniferous yomwe imagwiritsidwa ntchito kwambiri ndi mason pine, Yunnan pine, larch, spruce, etc.
3. Pali njira zambiri zamagulu a plywood, zomwe zingagawidwe molingana ndi mitundu ya mitengo, monga plywood yolimba (birch plywood, plywood tropical hardwood plywood, etc.) ndi coniferous plywood;
4. Malingana ndi cholingacho, chikhoza kugawidwa kukhala plywood wamba ndi plywood yapadera. Plywood wamba ndi plywood yoyenera pazifukwa zosiyanasiyana, ndipo plywood yapadera ndi plywood pazifukwa zapadera;
5. Malinga ndi kukana kwa madzi ndi kulimba kwa zomatira zosanjikiza, plywood wamba imatha kugawidwa kukhala plywood yolimbana ndi nyengo (gulu loyamba la plywood, lolimba, kukana kuwira kapena kutentha kwa nthunzi, lingagwiritsidwe ntchito panja), plywood yosagwira madzi (kalasi II). plywood, ikhoza kuviikidwa m'madzi ozizira, kapena kuviikidwa m'madzi otentha kwa nthawi yochepa, koma osagonjetsedwa ndi kuwira) Plywood yosamva chinyezi (Plywood ya Class III, yomwe imatha kupirira kumizidwa m'madzi ozizira kwakanthawi kochepa ndipo ndi yoyenera kugwiritsidwa ntchito m'nyumba) ndi plywood yosamva chinyezi (plywood ya kalasi IV, yomwe imagwiritsidwa ntchito m'nyumba yabwinobwino komanso imakhala ndi mphamvu zomangirira).
6. Malingana ndi mapangidwe a plywood, akhoza kugawidwa kukhala plywood, sandwich plywood ndi plywood composite. Sangweji ya plywood ndi plywood yokhala ndi pulasitiki, ndipo plywood yopangidwa ndi plywood ndi plywood yokhala ndi pulasitiki (kapena zigawo zina) zopangidwa ndi zipangizo zina osati matabwa olimba kapena veneer. Mbali ziwiri za pachimake mbale nthawi zambiri amakhala ndi zigawo ziwiri za veneers ndi matabwa njere vertically anakonza ndi mzake.
7. Malinga ndi kukonzedwa pamwamba, akhoza kugawidwa mu mchenga plywood, scraped plywood, veneered plywood ndi pre veneered plywood. Mchenga wa plywood ndi plywood yomwe pamwamba pake imapangidwa ndi mchenga ndi mchenga, plywood yowonongeka ndi plywood yomwe pamwamba pake imadulidwa ndi scraper, ndipo plywood yopangidwa ndi veneer ndi zinthu zowoneka ngati zokongoletsera, mapepala a tirigu, mapepala opangidwa ndi pulasitiki, pulasitiki, filimu yomatira utomoni kapena pepala lachitsulo, Plywood yomalizidwa kale ndi plywood yomwe yakhala ikugwiritsidwa ntchito mwapadera panthawi yopangidwa ndipo sichiyenera kusinthidwa panthawi yogwiritsidwa ntchito.
8. Malinga ndi mawonekedwe a plywood, akhoza kugawidwa mu plywood plywood ndi kupanga plywood. Plywood yopangidwa imatanthawuza plywood yomwe idakanikizidwa mwachindunji mumpangidwe wokhotakhota mu nkhungu malinga ndi zofunikira za chinthucho, pazosowa zapadera, monga bolodi lachitetezo cha khoma, matabwa a denga, kumbuyo ndi miyendo yakumbuyo yampando.
9. Njira yodziwika bwino yopangira plywood ndi njira yowuma yowuma, ndiko kuti, pambuyo pothira zitsulo zowuma ndi zomatira, zimayikidwa muzitsulo zotentha kuti zigwirizane ndi plywood. Njira zazikuluzikulu zimaphatikizira kulemba zipika ndi kuwotcha pamtanda, chithandizo cha kutentha kwa gawo lamatabwa, kuyika matabwa ndi kudula mozungulira, kuyanika kwa veneer, kusanja kwa veneer, kukonzekera kwa slab, kukanikiza kwa slab, kukanikiza kotentha, komanso chithandizo chambiri pambuyo pake.
Cholinga cha chithandizo cha kutentha kwa nkhuni ndikufewetsa zigawo zamatabwa, kuonjezera pulasitiki ya zigawo zamatabwa, kuthandizira zigawo zamatabwa zotsatiridwa kuti zidulidwe kapena kukonzedwa, ndikuwongolera mtundu wa veneer. Njira zodziwika bwino zochizira kutentha kwa gawo la nkhuni zimaphatikizapo kuwira, kuthira madzi ndi mpweya munthawi imodzi, komanso kutentha kwa nthunzi.
