Choyamba, tanthauzo la plywood Plywood ndi thabwa lopangidwa ndi matabwa ozungulira kukhala ma veneers akuluakulu molunjika kwa mphete zapachaka, kuyanika ndi kumamatira, kenako kupanga zosoweka ndikumamatira molingana ndi mfundo yakuti mayendedwe ambewu yamatabwa a zigawo zoyandikana ndi veneer. ndi perpendicular kwa wina ndi mzake.Kuchuluka kwa zigawo za veneer ndizosamvetseka, nthawi zambiri zigawo zitatu mpaka khumi ndi zitatu, plywood zitatu, plywood zisanu, plywood zisanu ndi zinayi, ndi plywood khumi ndi zitatu (zomwe zimadziwika kuti plywood zitatu, plywood zisanu, plywood zisanu ndi zinayi, plywood khumi ndi zitatu pamsika) mbale).Chovala chakunja chakutsogolo chimatchedwa gulu, chotsaliracho chimatchedwa backplane, ndipo chamkati chimatchedwa core board.
Gulu la plywood
Mtundu umodzi wa plywood ndi plywood yolimbana ndi nyengo komanso yosawira madzi otentha, yomwe ili ndi ubwino wokhalitsa, kukana kutentha, ndi kutentha kwa nthunzi;
Mtundu wachiwiri wa plywood ndi plywood yosagwira madzi, yomwe imatha kuviikidwa m'madzi ozizira ndi madzi otentha kwa nthawi yochepa;
Mtundu wachitatu wa plywood ndi plywood yosamva chinyezi, yomwe imatha kumizidwa m'madzi ozizira kwakanthawi kochepa ndipo ndi yoyenera kugwiritsidwa ntchito m'nyumba kutentha.zopangira mipando ndi zomangamanga;
Mitundu inayi ya plywood si plywood yosamva chinyezi, yomwe imagwiritsidwa ntchito m'nyumba yabwinobwino.Zida za plywood zomwe zimagwiritsidwa ntchito nthawi zonse ndi monga beech, basswood, phulusa, birch, elm, ndi poplar.
Mfundo yopangira
Mfundo ya Symmetry: Veneer kumbali zonse ziwiri za symmetrical center ndege, mosasamala kanthu za makulidwe a veneer, kuchuluka kwa zigawo, njira yopangira, njira ya fiber ndi chinyezi cha veneer, ziyenera kugwirizana. , mfundo yofananira ya plywood kumbali zonse za ndege yapakati Zigawo zofananira zili m'njira zosiyanasiyana.Kupanikizika ndi kofanana ndi kukula kwake.Choncho, pamene chinyezi cha plywood chimasintha, mapangidwe ake ndi okhazikika, ndipo sipadzakhala zolakwika monga kusokoneza ndi kusweka;m'malo mwake, ngati pali kusiyana pakati pa zigawo lolingana mbali zonse za symmetrical likulu ndege, kupsyinjika kwa veneer mbali zonse za symmetrical likulu ndege sichidzakhudzidwa.Mofananamo, plywood idzakhala yopunduka komanso yosweka.
Mfundo yosamvetseka: Popeza mapangidwe a plywood ndikuti maulalo a ulusi wa zigawo zoyandikana za veneers ndi perpendicular kwa wina ndi mzake ndipo ayenera kutsatira mfundo ya symmetry, chiwerengero chake chonse cha zigawo ayenera kukhala nambala yosamvetseka.Monga: atatu wosanjikiza bolodi, asanu wosanjikiza bolodi, asanu wosanjikiza bolodi, etc. Pamene osawerengeka owerengeka plywood ndi akupiringa, pazipita yopingasa kukameta ubweya maganizo amachita pa pakati veneer, zomwe zimapangitsa kukhala ndi mphamvu yaikulu.Pamene plywood yokhala ndi manambala imapindika, kupanikizika kwakukulu kwa kukameta ubweya kumachita pa zomatira m'malo mwa veneer, zomwe zimakhala zosavuta kuwononga zomatira ndikuchepetsa mphamvu ya plywood.
Zokongoletsa mapanelo
Dzina lonse la chovalacho ndi chokongoletsera chokongoletsera plywood.Ndi mtundu wamtundu womwe umagwiritsidwa ntchito kukongoletsa mkati kapena kupanga mipando, yomwe imapangidwa podula matabwa achilengedwe kapena matabwa aukadaulo kukhala magawo oonda amtundu wina, kumamatira pamwamba pa plywood, kenako kukanikiza kotentha.Zakuthupi.Zovala zamtundu wamba zimagawidwa kukhala zoveketsa zamatabwa zachilengedwe komanso zopangira zopangira.Kusiyanitsa kwa maonekedwe pakati pa zojambula zowonongeka ndi matabwa achilengedwe ndizokuti mawonekedwe oyambirirawo ndi olunjika kapena okhazikika;pamene chotsiriziracho ndi matabwa achilengedwe ndi mapangidwe achilengedwe ndi chitsanzo, ndi kusiyana kwakukulu ndi kusakhazikika.Makhalidwe ake: sikuti ali ndi chitsanzo chokongola cha nkhuni, komanso amakwaniritsa ntchito zonse zamatabwa ndi kuchepetsa ndalama.
Plywood ndi plywood yopangidwa kuchokera ku nkhuni monga zopangira zazikulu.Chifukwa cha kumveka kwa kapangidwe kake ndi kukonza bwino popanga, zimatha kuthana ndi zolakwika zamatabwa ndikuwongolera kwambiri ndikuwongolera mawonekedwe akuthupi ndi makina amitengo.Kupanga plywood ndiko kugwiritsa ntchito nkhuni mokwanira komanso moyenera., njira yofunikira yopititsira patsogolo ntchito zamatabwa.Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pamipando ndi gulu lamatabwa.Gulu la veneer nthawi zambiri amapangidwa ndi gluing moyandikana zigawo za matabwa mbewu perpendicular kwa mzake.Kawirikawiri, mbale pamwamba ndi wosanjikiza wamkati anakonza symmetrically mbali zonse za pakati wosanjikiza kapena pachimake.Ndi slab yopangidwa ndi zingwe zomatira zomwe zimadutsana ndi njere zamatabwa, ndipo zimakanikizidwa ndi kutentha kapena kusatenthedwa.Chiwerengero cha zigawo nthawi zambiri chimakhala chosamvetseka, ndipo ena amakhala ofanana.The thupi ndi makina katundu mu ofukula ndi yopingasa malangizo ndi osiyana pang'ono.Zomwe zimagwiritsidwa ntchito ndi plywood zitatu, plywood zisanu ndi zina zotero.Plywood imatha kupititsa patsogolo kuchuluka kwa nkhuni ndipo ndi njira yayikulu yopulumutsira nkhuni.Itha kugwiritsidwanso ntchito ngati ndege, zombo, masitima apamtunda, magalimoto, nyumba ndi mabokosi onyamula.
