Apa, opanga plywood aku China amakukumbutsani kuti pogula plywood, ndikofunikira kupeza wopanga gwero kuti musankhe mwaukadaulo, wotetezeka komanso wachuma.
plywood ndi chiyani
Plywoodndi imodzi mwazinthu zosunthika komanso zodziwika bwino zamapanelo opangidwa ndi matabwa zomwe zimagwiritsidwa ntchito pomanga zosiyanasiyana padziko lonse lapansi. Amapangidwa pomanga utomoni ndi ma sheet a matabwa kuti apange zinthu zophatikizika zomwe zimagulitsidwa mu mapanelo. Nthawi zambiri, plywood imakhala ndi ma veneers apamwamba kuposa ma core veneers. Ntchito yayikulu ya zigawo zapakati ndikuwonjezera kulekanitsa pakati pa zigawo zakunja komwe kupanikizika kopindika kumakhala kwakukulu, potero kumawonjezera kukana kwa mphamvu zopindika. Izi zimapangitsa plywood kukhala chisankho chabwino kwambiri pamapulogalamu omwe amafunikira mphamvu komanso kusinthasintha.
Chidziwitso cha njira zopangira
Plywood, yomwe imadziwika kuti multilayer board, veneer board, kapena core board, imapangidwa podula ma veneers kuchokera pamagawo a chipika ndiyeno kumamatira ndikuwotcha ndikukanikizira magawo atatu kapena kupitilira apo (zosawerengeka) za bolodi. Kupanga plywood kumaphatikizapo:
Kudula mitengo, kusenda, ndi kudula; Zowumitsa zokha; Full splicing; Gluing ndi billet msonkhano; Kuzizira kozizira ndi kukonza; Kutentha kotentha ndi kuchiritsa; Kucheka, kukwapula, ndi mchenga; Zopondereza katatu, kukonza katatu, macheke katatu, katatu mchenga; Kudzaza; Anamaliza kufufuza mankhwala; Kupaka ndi kusunga; Mayendedwe
Kudula ndi Kutchetcha
Peeling ndiye ulalo wofunikira kwambiri pakupanga plywood, ndipo mtundu wa peeled veneer umakhudza mwachindunji mtundu wa plywood yomalizidwa. Zipika zokhala ndi mainchesi opitilira 7cm, monga bulugamu ndi paini wosiyanasiyana, amadulidwa, kusenda, kenaka amadulidwa kukhala ma veneers okhala ndi makulidwe osakwana 3mm. Ma veneers osenda amakhala ndi makulidwe abwino, samakonda kulowa ndi glue, komanso amakhala ndi mawonekedwe okongola a radial.
Kuyanika Zodzichitira
Njira yowumitsa imagwirizana ndi mawonekedwe a plywood. Zopangira peeled ziyenera kuwumitsidwa munthawi yake kuti zitsimikizire kuti chinyezi chake chikufika pakupanga plywood. Pambuyo pa kuyanika kwa makina, chinyezi cha veneers chimayang'aniridwa pansi pa 16%, gulu lankhondo ndi laling'ono, losavuta kupunduka kapena delaminate, ndipo ntchito yokonza ma veneers ndi yabwino kwambiri. Poyerekeza ndi njira yachizoloŵezi yowumitsa zachilengedwe, kuyanika kwachangu sikumakhudzidwa ndi nyengo, nthawi yowumitsa ndi yochepa, mphamvu yowumitsa tsiku ndi tsiku imakhala yamphamvu, kuyanika kwabwino kumakhala kokwera, liwiro liri mofulumira, ndipo zotsatira zake zimakhala bwino.
Kuphatikiza Kwathunthu, Gluing, ndi Billet Assembly
Njira yophatikizira ndi zomatira zomwe zimagwiritsidwa ntchito zimatsimikizira kukhazikika komanso kuyanjana kwachilengedwe kwa bolodi la plywood, lomwenso ndilo vuto lalikulu kwa ogula. Njira yaposachedwa yolumikizirana pamakampani ndi njira yonse yolumikizirana komanso njira yolumikizira mano. Zouma zouma ndi zowonongeka zimayikidwa mu bolodi lalikulu kuti zitsimikizidwe bwino komanso zolimba za veneers. Pambuyo pa ndondomeko ya gluing, ma veneers amakonzedwa mwadongosolo la crisscross molingana ndi ndondomeko yambewu yamatabwa kuti apange billet.
Kuzizira Kozizira ndi Kukonza
Kupondereza kozizira, komwe kumadziwikanso kuti pre-pressing, kumagwiritsidwa ntchito kuti ma veneers azitsatirana, kuteteza zolakwika monga kusamuka kwa veneer ndi core board stacking panthawi yosuntha ndi kunyamula, komanso kuonjezera madzi a guluu kuti athandizire kupanga filimu yabwino ya guluu pamwamba pa zitsulo, kupewa chodabwitsa cha kusowa kwa guluu ndi guluu wouma. Billet imatengedwa kupita ku makina osindikizira asanayambe ndipo pambuyo pa mphindi 50 za kukanikiza kozizira kofulumira, bolodi lalikulu limapangidwa.
Board billet kukonza ndi njira yowonjezera isanayambe kukanikiza kotentha. Ogwira ntchito amakonza pamwamba pa core board wosanjikiza ndi wosanjikiza kuti atsimikizire kuti pamwamba pake ndi yosalala komanso yokongola.
Kutentha Kwambiri ndi Kuchiritsa
Makina osindikizira otentha ndi chimodzi mwazinthu zofunika kwambiri popanga plywood. Kukanikiza kotentha kumatha kupewa zovuta zamapangidwe a thovu ndi delamination wakomweko mu plywood. Pambuyo pa kukanikiza kotentha, billet imayenera kukhazikika kwa mphindi pafupifupi 15 kuti zitsimikizire kuti kapangidwe kake kamakhala kokhazikika, mphamvu ndi yayikulu, ndikupewa kupunduka kwankhondo. Njirayi ndi yomwe timatcha nthawi ya "kuchiritsa".
Kucheka, Kupukuta, ndi Kudula Mchenga
Pambuyo pa nthawi yochiritsa, billet idzatumizidwa ku makina ocheka kuti adulidwe muzofanana ndi kukula kwake, kofanana ndi kokongola. Kenako, pamwamba pa bolodi amapakulitsidwa, kuuma, ndi mchenga kuti zitsimikizire kusalala bwino, mawonekedwe owoneka bwino, ndi gloss yabwino ya bolodi. Pakadali pano, gawo loyamba la njira 14 zopangira zopangira plywood zatha.
Kupondereza katatu, kukonza katatu, macheke katatu, ndi mchenga katatu
Plywood yapamwamba imafunika kudutsa njira zingapo zopukutira bwino. Pambuyo pa mchenga woyamba, plywood idzayang'ananso kachiwiri, kukanikiza kozizira, kukonza, kukanikiza kotentha, kucheka, kupukuta, kuyanika, kupukuta mchenga, ndi kukwapula, zonse 9 mu kuzungulira kwachiwiri.
Potsirizira pake, billet imayikidwa ndi matabwa okongola komanso okongola, pamwamba pa mahogany, ndipo plywood iliyonse imadutsanso kuzizira kwachitatu, kukonzanso, kukanikiza kotentha, kupukuta, kupukuta mchenga, kucheka, ndi zina 9 njira. Chiwerengero cha "zosindikizira zitatu, kukonza katatu, macheka atatu, mchenga atatu" 32 kupanga njira zopangira, bolodi lomwe ndi lathyathyathya, lokhazikika, lokhala ndi mapindikidwe ochepa, ndipo ndi lokongola komanso lolimba limapangidwa.
Kudzaza, Kumaliza Kukonza Zinthu
Plywood yopangidwa imawunikiridwa ndikudzazidwa pambuyo poyang'anitsitsa komaliza ndikusanja. Kupyolera mu kuyesa kwa sayansi kwa makulidwe, kutalika, m'lifupi, chinyezi, ndi khalidwe lapamwamba, ndi miyezo ina, kuonetsetsa kuti plywood iliyonse yopangidwa ndi yoyenerera komanso yokhazikika, yogwira ntchito bwino komanso yokonza.
Kupaka ndi Kusunga
Pambuyo pomaliza kusankhidwa, ogwira ntchito amanyamula plywood kuti asungidwe kuti asatengere dzuwa ndi mvula.
TONGLI TIMBER
Kodi plywood imagwiritsidwa ntchito bwanji?
Plywood ndi mtundu wamba wa bolodi womwe umagwiritsidwa ntchito m'mafakitale osiyanasiyana. Iwo agawidwa m'maguluplywood wambandiplywood yapadera.
Ntchito zazikulu zaplywood yapaderandi izi:
1.Giredi imodzi ndiyoyenera kukongoletsa zomangamanga zapamwamba, mipando yapakatikati mpaka yapamwamba, ndi ma casings amagetsi osiyanasiyana.
2.Gulu lachiwiri ndiloyenera mipando, zomangamanga, galimoto, ndi zokongoletsera za sitima.
3.Gulu lachitatu ndiloyenera kukonzanso nyumba zotsika komanso zopangira zinthu. Gulu lapadera ndiloyenera zokongoletsera zomangamanga zapamwamba, mipando yapamwamba, ndi zinthu zina zomwe zili ndi zofunikira zapadera.
Plywood wambaamaikidwa m'magulu a I, Class II, ndi Class III kutengera zolakwika zowoneka ndi zolakwika pakukonza plywood pambuyo pokonza.
1.Class I plywood: Plywood yosagwira nyengo, yomwe imakhala yolimba ndipo imatha kupirira kutentha kapena kutentha kwa nthunzi, yoyenera kugwiritsidwa ntchito panja.
2.Pulogalamu ya Class II: Plywood yosagwira madzi, yomwe imatha kuthiridwa m'madzi ozizira kapena kuyika madzi otentha kwa nthawi yochepa, koma si yoyenera kuwira.
3.Pulogalamu ya Class III: Plywood yosamva chinyezi, yomwe imatha kupirira madzi ozizira kwa nthawi yochepa, yoyenera kugwiritsidwa ntchito m'nyumba.
