OSB (Oriented Strand Board)

Ndi chiyaniOSB (OmakondaStrand Bpansi)

OSBndi imodzi mwa mitundu yatsopano ya particle board.Pa mapangidwe tinthu kuyatsa, chapamwamba ndi m'munsi pamalo a oriented strand tinthu bolodi anakonza longitudinally mu CHIKWANGWANI malangizo a osakaniza tinthu bolodi, pamene pachimake wosanjikiza particles anakonza horizontally kupanga atatu wosanjikiza structural bolodi mwana wosanjikiza. ndiye otentha mbamuikha mu oriented strand tinthu bolodi.Maonekedwe a mtundu uwu wa tinthu bolodi amafuna ndi lalikulu mbali chiŵerengero, ndipo makulidwe a particles ndi wokhuthala pang'ono kuposa wamba tinthu matabwa.Njira zopangira zowongolera zimaphatikiza kuwongolera kwamakina ndi ma electrostatic orientation.Yoyamba ndi yabwino kwa tinthu tating'ono zochokera pansi paving, pamene yotsirizira ndi oyenera yaing'ono tinthu zochokera kupondaponda.Kuyika kwa ma particle board omwe amawongolera kumapereka mawonekedwe amphamvu kwambiri mbali ina yake ndipo nthawi zambiri amagwiritsidwa ntchito ngati zomangira m'malo mwa plywood.

OSBndi matabwa a tinthu tating'onoting'ono opangidwa makamaka ndi matabwa ang'onoang'ono a nkhalango zotakata, ndi matabwa omwe amakula mofulumira, ndipo amasinthidwa kupyolera mu njira monga kupukuta, kuyanika, gluing, kupaka njira, ndi kukanikiza kotentha.Imadziwikanso kuti oriented strand board.Ili ndi misomali yabwino kwambiri, mphamvu yodzilimbitsa, yogwirizana ndi chilengedwe, komanso kukana chinyezi.Makamaka okonda zachilengedwe, kugwiritsa ntchito zomatira za isocyanate (MDI) ngati zomangira, zopanda fungo loyipa, ndizathanzi komanso zachilengedwe.

Kupanga ndondomeko yaOSB

1. Kukonzekera kwa zipangizo

OSB imapangidwa ndi matabwa ang'onoang'ono komanso nkhuni zomwe zimakula mwachangu ndi mainchesi 8 mpaka 10.Zopangira zamatabwa zimasenda ndipo zonyansa zimachotsedwa pogwiritsa ntchito zida zapadera, kenako ndikusinthidwa kukhala tinthu tating'onoting'ono tating'ono tating'ono ta mawonekedwe a geometric.

2. Kuyanika

Chowumitsira cha oriented strand board nthawi zambiri chimagwiritsa ntchito chowumitsira tchanelo chimodzi, pogwiritsa ntchito ukadaulo wanthawi yayitali wowumitsa kutentha.Njira yonse yowumitsa imagawidwa mu siteji yowumitsa, kuyanika, ndi siteji yofanana, ndipo pamapeto pake iyenera kuwonetsetsa kuti chinyezi cha chipboard chikuyendetsedwa pafupifupi 2%.

3. Kusankha tinthu

Pali mitundu iwiri ya kusanja tinthu, imodzi ndiyo kugwiritsa ntchito njira zamakina kusanja tinthu tating'onoting'ono molingana ndi miyeso ya geometric kudzera m'ma gridi okhala ndi ma apertures osiyanasiyana kapena mipata, ndipo ina ndiyo kusankha tinthu tating'onoting'ono tosiyanasiyana komanso kuyimitsidwa koyimitsidwa posintha liwiro la mpweya.

4. Paving Directional

Sakanizani pamwamba wosanjikiza wa shavings ndi guluu ndi kukonza iwo vertically mu ulusi malangizo, pamene pachimake wosanjikiza wa shavings anakonza horizontally kupanga atatu wosanjikiza dongosolo la gulu mluza.Pomaliza, gulu lamitundu yambiri la bolodi limapangidwa ndi kukanikiza kotentha.

Makhalidwe aOSB

1. Zokolola zambiri zakuthupi

Poyerekeza ndi mitundu ina ya matabwa yokumba, oriented strand tinthu bolodi ali zokolola apamwamba, ndi kupanga zochokera strand tinthu bolodi ntchito yaing'ono m'mimba mwake matabwa matabwa wasintha chikhalidwe chofewa yaing'ono m'mimba mwake matabwa zipangizo, kupanga izo apamwamba yokumba bolodi ndi mphamvu zapamwamba ndi kukhazikika.Izi sizimangowonjezera kuchuluka kwa ntchito zamatabwa ku China, komanso zimachepetsanso kusowa kwa zida zogulitsira kuchokera kunja.

2. Chitetezo ndi kuteteza chilengedwe

Popanga, isocyanate (MDI) idagwiritsidwa ntchito m'malo mwa zomatira zachikhalidwe za phenolic resin, zokhala ndi kuchuluka kwa ntchito komanso kutsika kwa formaldehyde, zomwe sizingawononge chilengedwe komanso thanzi la anthu.Ndi otetezeka ndi chilengedwe wochezeka zobiriwira.

3. Kuchita bwino kwambiri

Zakuthupi komanso zamakina a OSB ndizapamwamba kwambiri kuposa bolodi wamba, makamaka okhala ndi izi:

(1) Anti deformation, anti peeling, anti warping, yokhala ndi mawonekedwe monga mphamvu yofanana ndi kukula kokhazikika.

(2) Anticorrosive, mothproof, mphamvu yamoto retardant, yoyenera panja ndi kutentha kwambiri;

(3) Kuchita bwino kosalowa madzi, kumatha kuwonetsedwa kumadera achilengedwe komanso chinyezi kwanthawi yayitali;

(4) Kukhala ndi magwiridwe antchito amakina abwino, kumatha kudulidwa, kubowola, ndi kukonzedwa mbali iliyonse;

(5) Ili ndi zotchingira zabwino kwambiri komanso zotulutsa mawu, komanso utoto wabwino.

Kugwiritsa ntchito kwaOSB

1. Mipando

Zowoneka bwino komanso zamakina zamakina opangidwa ndi tinthu tating'onoting'ono zimatsimikizira kuti zitha kugwiritsidwa ntchito ngati gawo lonyamula katundu monga sofa, makabati a TV, makabati am'mphepete mwa bedi, matebulo ndi mipando, komanso atha kugwiritsidwa ntchito mumipando yamapaneli kupanga magawo a makabati. , mapanelo apakompyuta, mapanelo a zitseko, ndi zina zotero.

2. Kukongoletsa mkati

Oriented strand board ndi yokongoletsa kwambiri, ndipo mitundu yosiyanasiyana yamitengo imatha kuwonetsa mawonekedwe ndi mitundu yosiyanasiyana.Mosiyana wosakhwima ndi yosalala yokumba matabwa, oriented strand tinthu bolodi ali wapadera ndi akhakula kapangidwe pamwamba chifukwa ofukula ndi yopingasa makonzedwe a flakes.Monga chinthu chokongoletsera, chimakhala ndi chilengedwe komanso chowoneka bwino chikagwiritsidwa ntchito pa zokongoletsera zamkati.

3. Zida zoyikamo

Oriented strand particle board ndi chinthu chodziwika padziko lonse lapansi choyang'anira ma CD chaulere, chomwe chili ndi mphamvu zabwino komanso zosagwirizana ndi madzi kuposa bolodi lamatabwa lolimba.
