Plywood ndi mtundu wamatabwa wopangidwa ndi anthu womwe umakumananso ndi khungu.
Plywood imapangidwa ndikudula m'malo akulu akulu mozungulira mphete zapachaka. Pambuyo kuyanika ndi kulumikizana, imapangidwa molingana ndi muyezo wa mawonekedwe ofukula wa mahogany wa veneers oyandikana nawo.
Chiwerengero cha matabwa oyambira nthawi zambiri chimakhala chosamvetseka, nthawi zambiri magawo atatu kapena khumi ndi atatu, ndipo magawo wamba amakhala zigawo zitatu, zigawo zisanu, zigawo zisanu ndi zinayi, ndi magawo 13 (msika wogulitsa umatchedwa plywood zitatu, zisanu plywood, plywood zisanu ndi zinayi, masentimita khumi ndi atatu). Choyang'ana kutsogolo chakunja kumatchedwa gulu lakumaso, kumbuyo kumatchedwa gulu lakumbuyo, ndipo gawo lamkati limatchedwa bolodi lalikulu.
Mtundu wa plywood 1 uli ndi ubwino wokana nyengo, madzi otentha, kulimba, kutentha kwambiri, komanso kukana nthunzi.
Mitundu iwiriyi ya plywood ndi plywood yopanda madzi, yomwe imatha kuviikidwa m'madzi ozizira komanso madzi otentha munthawi yochepa.
Mtundu wa 3 plywood ndi plywood yopanda madzi, yomwe imatha kumizidwa m'madzi ozizira kwakanthawi kochepa, komwe kuli koyenera kutenthetsera mkati. Mipando ndi zomangamanga;
Mtundu wa plywood 4 ndi plywood yosagwira chinyezi, yomwe imagwiritsidwa ntchito kwambiri m'nyumba. Plywood yomwe imagwiritsidwa ntchito nthawi zambiri imaphatikizapo birch, bulugamu, ndi popula.
Plywood imagwiritsidwa ntchito kwambiri panja, monga kukongoletsa kunja kwa nyumba ndi mawonekedwe a konkriti. Pokongoletsa, imagwiritsidwa ntchito makamaka kudenga, masiketi apampanda, ndi zapansi.
Zomwe zimapangidwira plywood
Pofuna kukonza matabwa achilengedwe momwe zingathere, plywood imakhala ndi mawonekedwe ofanana ndi mawonekedwe okhazikika. Nthawi zambiri, plywood imayenera kutsatira mfundo ziwiri zofunikira: imodzi ndiyofanana; china ndikuti pafupi ndi bolodi lamtundu umodzi limayenderana.
Mfundo yofananira ndiyoti plywood imafunika mbali zonse ziwiri za ndege yofananira, mosasamala kanthu za nkhuni, makulidwe a plywood, kuchuluka kwa zigawo, kulumikizana kwa ulusi, ndi chinyezi okhutira ayenera symmetrical wina ndi mnzake.
Mu plywood yomweyo, mitengo imodzi ndi oundana okhwima atha kugwiritsidwa ntchito, kapena veneers amitengo ndi makulidwe osiyanasiyana angagwiritsidwe ntchito; komabe, magawo awiri amitengo yolumikizana yolingana ndi mbali zonse ziwiri za ndege yolumikizirana ndiyofanana.
Pofuna kuti mapangidwe a plywood akwaniritse mfundo ziwiri pamwambapa, kuchuluka kwa zigawo ziyenera kukhala zosamvetseka.
Chifukwa chake, plywood nthawi zambiri imagawika magawo atatu, magawo asanu, magawo asanu ndi awiri ndi mitundu ina yosamvetseka.
Dzinalo la plywood wosanjikiza ndi: mawonekedwe owonekera amatchedwa tebulo, mawonekedwe amkati amatchedwa bolodi yayikulu; gulu lakumaso limatchedwa gulu, ndipo kumbuyo kumbuyo kumatchedwa gulu lakumbuyo; mu bolodi lalikulu, cholumikizira cholumikizira chikufanana ndi gululi.
Amatchedwa bolodi yayitali yayikulu kapena pakati pa bolodi.
Ubwino plywood
Ubwino plywood ndi amphamvu zimakhudza mphamvu, zovuta deform ndi unakhota, zovuta osokoneza, ndi kukula ang'onoang'ono. Multilayer board imatha kusintha kuzolowera m'nyumba ndi chinyezi. Malo osanjikiza a multilayer board ndi matabwa achilengedwe. Njere za nkhuni zili pafupi ndi chilengedwe ndipo mawonekedwe ake ndi akulu. Ubwino wama board angapo osanjikiza ndiosavuta kuwumbapo. Poyerekeza ndi chipika cholimba, bolodi lamitundu ingapo limapewa zolakwika zina zamatabwa achilengedwe, monga chibwibwi, m'lifupi, mapindikidwe, komanso kukanikiza pang'ono.
Ma board angapo osanjikiza amakhalanso ndi mwayi woposa matabwa achilengedwe pamtengo. Popeza matabwa amitundu yambiri amasanthulanso ndikukonzanso mitengo, imakhala yotsika mtengo kuposa mitengo yamtengo wapatali yolimba.
Zoyipa zama board angapo
Bolodi losanjikiza limapangidwa ndi matabwa achilengedwe amtengo wapakati pamatenthedwe otentha komanso kukanikizika kwambiri mumakina otentha ndi zomatira. Chifukwa chake, poteteza zachilengedwe, padzakhala kutulutsa kwa formaldehyde. Koma ili pafupi kwambiri ndi matabwa achilengedwe ndipo ndiyonso bolodi yokumba yosavuta kuwononga zachilengedwe.
Kuzindikiritsa plywood yabwino kapena yoyipa
Choyamba, yang'anani kusunthika kwa gululi. Kuchokera pano, titha kuwona zinthu zamkati mwa bolodi. Tikayang'ana bolodi, titha kuigwira ndi manja athu ndikumva ngati pali kusiyana kulikonse. Ngati alipo, zikutanthauza kuti mchenga wapamwamba si wabwino.
Mwina zikutanthauza kuti pachimake bolodi zakuthupi sizabwino ndipo nkhaniyi ndi yosweka. Mwachidule, sikulimbikitsidwa kugula zosagwirizana.
Chachiwiri, onaninso malingaliro olowezana a board multilayer. Kukula kwa bolodi, ndikosavuta kuwona kuyika kwa bolodi losanjikiza. Ngati gawo lililonse limapangidwa ndi zinthu za monolithic, zigawozo zidzakhala zomveka bwino ndipo sipadzakhala zochitika zapadera. Ngati nkhaniyo siyabwino, pamakhala zinyalala zambiri.
Chifukwa cha kukakamizidwa, msinkhuwo umakulirakulira mukapanikizana.
