OSBndi wamphamvu kuposa plywood mu kukameta ubweya.Kumeta ubweya wa ubweya, kupyolera mu makulidwe ake, ndi pafupifupi 2 nthawi zambiri kuposa plywood.Ichi ndi chimodzi mwazifukwa zomwe osb amagwiritsiridwa ntchito pa ma intaneti a I-joists yamatabwa.Komabe, luso logwira misomali limawongolera magwiridwe antchito pamakhoma ometa ubweya.

Kaya mukumanga, kukonzanso, kapena mukungokonza, nthawi zambiri mumafunika mtundu wa sheathing kapena underlayment pa polojekitiyo.Zosankha zambiri zilipo pachifukwa ichi, koma zinthu ziwiri zomwe zimagwiritsidwa ntchito kwambiri ndi strand board (OSB) ndiplywood.Mapulani onsewa amapangidwa ndi matabwa okhala ndi zomatira ndi utomoni, amakhala ndi makulidwe ambiri, ndipo amatha kugwiritsidwa ntchito pazinthu zosiyanasiyana.Koma sikuti aliyense ali woyenera pa ntchito iliyonse.Tikulongosola kusiyana pakati pawo pansipa kuti mutha kupanga chisankho chodziwa bwino chomwe chidzagwire ntchito yanu.

Mmene Amapangidwira

OSB ndi plywood amapangidwa kuchokera ku timitengo ting'onoting'ono ndipo amabwera m'mapepala akuluakulu kapena mapanelo.Komabe, ndi pamene kufanana kumathera.Plywood amapangidwa ndi zigawo zambiri zamitengo yopyapyala kwambiri, yotchedwa plys, yopanikizidwa ndi guluu.Itha kuperekedwa pamwamba pamitengo yolimba, pomwe zigawo zamkati nthawi zambiri zimapangidwa ndi nkhuni zofewa.

OSB imapangidwa ndi tizidutswa tating'ono tating'ono ta nkhuni zolimba ndi zofewa zosakanizidwa pamodzi mu zingwe.Chifukwa zidutswazo ndi zazing'ono, mapepala a OSB akhoza kukhala aakulu kwambiri kuposa mapepala a plywood.Ngakhale kuti plywood nthawi zambiri imakhala mamita 6 pa pepala, OSB ikhoza kukhala yokulirapo, mpaka mamita 12 pa pepala.

Maonekedwe

Plywoodikhoza kukhala ndi masitayelo ndi mawonekedwe osiyanasiyana.Chosanjikiza chapamwamba nthawi zambiri chimakhala nkhuni zolimba ndipo zimatha kukhala matabwa angapo monga birch, beech, kapena mapulo.Izi zikutanthauza kuti pepala la plywood limatenga mawonekedwe a matabwa apamwamba.Plywood yopangidwa motere imapangidwira kumanga makabati, mashelefu, ndi zinthu zina zomwe matabwa amawonekera.

Plywood imathanso kupangidwa kuchokera ku mitengo yofewa yocheperako pagawo lake lapamwamba.Pankhaniyi, ikhoza kukhala ndi mfundo kapena pamwamba pake.Plywood iyi nthawi zambiri imagwiritsidwa ntchito pansi pa zinthu zomalizidwa, monga matailosi kapena m'mbali mwake.

OSB nthawi zambiri ilibe pamwambaveneer .Amapangidwa ndi zingwe zambiri kapena timitengo ting'onoting'ono topanikizidwa, zomwe zimapangitsa kuti ikhale yolimba.OSB sichigwiritsidwa ntchito pomaliza chifukwa sichikhoza kugwiritsira ntchito utoto kapena kuwononga momwe plywood yolimba imatha.Chifukwa chake, nthawi zambiri imayikidwa pansi pa chinthu chomaliza, monga siding.

Kuyika

Pankhani yopangira denga kapena denga, OSB ndi plywood ndizofanana kwambiri pakuyika.Kusiyana kokhako ndikuti OSB ndi yosinthika pang'ono kuposa plywood, yomwe ili ndi zabwino ndi zoyipa kutengera malo ndi mtunda pakati pa ma joists omwe akuphimbidwa.

Muzochitika zonsezi, zinthuzo zimakhala zazikulu, zimayikidwa molingana ndi ma joists, ndipo zimakhomeredwa bwino.

Kukhalitsa

OSB ndi plywood zimasiyana malinga ndi kulimba.OSB imatenga madzi pang'onopang'onokuposa plywood, yomwe ingakhale yopindulitsa m'madera omwe ali ndi chinyezi chochepa.Komabe, ikatenga madzi, imauma pang’onopang’ono.Imapindikanso kapena kutupa pambuyo pa kuyamwa madzi ndipo sichibwereranso ku mawonekedwe ake oyambirira.

Plywood imatenga madzimwachangu kwambiri, koma imaumanso msanga.Ikauma, imabwereranso m’maonekedwe ake onse.Mphepete mwa plywood imakananso kuwonongeka kuposa OSB, yomwe imatha kusweka ndikuwonongeka pakapita nthawi.

OSB ndi yolemera kuposa plywood ndipo, ikatetezedwa bwino ndi madzi ndi kusamalidwa, nthawi zambiri imakhala yosalala.OSB imakhalanso yosasinthasintha kuposa plywood.Plywood imapezeka m'mabwalo ambiri komanso magawo osiyanasiyana amtundu.OSB nthawi zambiri imakhala yosasinthika pagulu lonse, kutanthauza kuti zomwe mukuwona ndi zomwe mumapeza.

Plywood ndi OSB nthawi zambiri amaonedwa kuti ali ndi mphamvu zofanana.Komabe, popeza plywood yakhala ikuzungulira nthawi yayitali, yawonetsa kuti imatha zaka 50 kapena kuposerapo pakuyika.OSB ilibe mbiri yofananira chifukwa idangogulitsidwa kwa zaka pafupifupi 30.Mbiri yotsimikizika ya plywood nthawi zambiri imapangitsa anthu ena kukhulupirira kuti ndi chinthu chokhalitsa komanso chokhalitsa, koma izi sizowona.Mitundu yatsopano ya OSB, yomwe idawonedwa kuti ndi yopanda madzi, imatha kukhalabe ngati plywood muzochitika zofanana.

Mukagwiritsidwa ntchito pansi ngati gawo lapansi, plywood nthawi zambiri imatengedwa kuti ndi yabwino kwambiri.OSB imasinthasintha kuposa plywood.Ikagwiritsidwa ntchito pansi pa tile, imatha kugwedezeka ikakwera bwino, ndipo poyipa kwambiri, imatha kuyambitsagrout kapena tile yokha kuti iphwanyike.Pachifukwa ichi, plywood nthawi zambiri imakhala gawo lapansi lovomerezeka ngati gawo lapansi lamatabwa likufunika.

Nkhawa Zachilengedwe

Pazinthu ziwirizi, OSB imatengedwa ngati njira yobiriwira.Chifukwa OSB imapangidwa ndi matabwa ang'onoang'ono, imatha kupangidwa pogwiritsa ntchito mitengo yaying'ono, yomwe imakula mwachangu komanso kulimidwa.

Komabe, plywood imafunika kugwiritsa ntchito mitengo ya m'mimba mwake ikuluikulu, yomwe imadulidwa mozungulira kuti ipange zigawo zofunika.Mitengo ikuluikulu ngati iyi imatenga nthawi yayitali kuti ikule ndipo imayenera kudulidwa kuchokera ku nkhalango zakale, zomwe zimapangitsaplywoodanjira yochepa yobiriwira.

OSB ikupangidwabe pogwiritsa ntchito formaldehyde, komabe, plywood iyenera kupangidwa popanda mankhwalawa molingana ndi malamulo atsopano a chilengedwe pofika chaka.Plywood yolimba imapezeka kale ndi zomatira za soya ndi zinthu zina zomwe sizitulutsa urea-formaldehyde mumlengalenga.Ngakhale kuti n'zotheka kuti OSB idzatsatira zomwezo, posachedwapa zidzatheka kupeza plywood popanda formaldehyde kulikonse, pamene kupeza OSB popanda mankhwalawa kungakhale kovuta.

Kugulitsanso Mtengo

Palibe chilichonse chomwe chili ndi phindu lililonse pakugulitsanso nyumba.Zida zonsezi zimatengedwa ngati zomangika zikagwiritsidwa ntchito mofanana.Pogwiritsidwa ntchito mwadongosolo, zinthuzo zimabisika, ndipo nthawi zambiri sizimawululidwa panthawi yogulitsa, zomwe zikutanthauza kuti sizikhudzidwa ndi ndalama.
