Icyerekezo cya Strand Board (OSB) ni ubwoko bwububiko bwubatswe bukozwe muburyo buringaniye kandi buringaniye bwumye, bwerekanwe, bushyirwa hamwe nibindi byongeweho, kandi bishyushye nyuma yo gutondeka icyerekezo. Ifite imbaraga nyinshi kuko ikozwe mubice byinshi byimbaho. Mu Buyapani n'Uburayi no muri Amerika, OSB ifatwa nk'isahani ikura vuba, itanga icyizere kandi ikuze mu ikoranabuhanga.
Kugeza ubu, ikoreshwa rya OSB muri Amerika ryagize kimwe cya kabiri cy’ikoreshwa rusange ryakozwe n'abantu, kandi ryagiye risimbuza buhoro buhoro pani, icyuma n’ibindi bikoresho byakozwe n'abantu mu gukoresha byinshi.

Imiterere yubuyobozi bwa OSB

Nubwoko bwicyerekezo cyubatswe cyakozwe mubiti bito bya diametre, ibiti byoroheje hamwe nibiti byimbaho, bitunganyirizwa muri mm 40-100 z'uburebure, mm 5-20 z'ubugari na 0.3-0.7 mm z'uburebure hakoreshejwe ibikoresho bidasanzwe, kandi bigatunganywa na deoiling, gukama, gufunga, gushiraho icyerekezo, gukanda bishyushye nibindi bikorwa. Ubuso bwacyo bwa flake butunganijwe neza, kandi ibice byibanze bitondekanye. Iyi gahunda ya crisscross itunganya imiterere yimiterere yimbaho, ikuraho burundu ingaruka ziterwa nimbaho ​​zimbere mugutunganya, kandi byoroshye cyane gutunganya no kutagira ubushuhe.

Kuberako OSB ifite imiterere yicyerekezo, nta guhuza, gucamo, gucamo, guhuza neza muri rusange, hamwe nimbaraga zo hejuru zo guhuza imbere, haba hagati ndetse no kumpera ya OSB bifite ubushobozi bwo gufata imisumari ikomeye isahani isanzwe idashobora guhura. Twishingikirije ku Budage, ubwami bw’inganda zikora imiti, ibishishwa bikoreshwa ku isahani y’iburayi byahoraga bikomeza umwanya wa mbere ku isi. Imyuka ya formaldehyde y’ibicuruzwa byarangiye ihuye n’ibipimo bihanitse byo mu Burayi (igipimo cy’iburayi E1), gishobora kugereranywa n’ibiti bisanzwe.

Ibyiza nibiranga Ubuyobozi bwa OSB

1. Ifite imiterere yumubiri nubukanishi, imiterere yegeranye nimbaraga nyinshi.
2. Ifite ibintu bitatu biranga kurwanya deforme, gukuramo ibishishwa no kurwanya intambara.
3. Kurwanya ruswa, inyenzi zidashobora kwangirika, zirwanya ubumuga, hamwe n’umuriro ukomeye.
4. Imikorere yuzuye idafite amazi, irashobora guhura burundu nibidukikije nibihe bitose.
5. Ibyuka bihumanya ikirere ni bike cyane, nigicuruzwa nyacyo cyo kurengera ibidukikije.
6. Gufata imisumari ikomeye, byoroshye kubona, imisumari, umwitozo, ahantu, indege, dosiye cyangwa umucanga.
7. Ifite ubushyuhe buhebuje, ingaruka zo gukurura amajwi no gukora neza.

Intego yimikorere ya OSB
OSB ifite ituze ryiza hamwe ningufu ndende zifata imbaraga. Ibikoresho byayo bibisi ahanini ni ibiti byoroshye, ibiti bito bito bya diametre, ibiti bikura vuba vuba, nibindi, nka eucalyptus, fir, ibiti byangiza ibiti, nibindi, bifite amasoko menshi kandi bishobora gukorerwa mubice binini (nkibi nka metero 8 × 32 cyangwa metero 12 × 24). Igikorwa cyo gukora cyane cyane kumisha, kole, icyerekezo no gushyushya-kanda shavings ifite imiterere ya geometrike (mubisanzwe mm 50 - mm 80 z'uburebure, mm 5 - 20 mm z'ubugari, na 0,45 mm - 0,6 mm z'ubugari). Ikibazo cya tekiniki ni kinini, kandi ishoramari ryibikoresho ni rinini cyane, kubikoresho bitumizwa mu mahanga, ahanini kuri miliyari nyinshi cyangwa zirenga. Kugeza ubu, Ubushinwa "OSB" bwo gukora inganda n’ubushobozi bwo gukora ibikoresho biri inyuma cyane y’Amerika y'Amajyaruguru n'Uburayi. Kugeza ubu, "OSB" nyamukuru ku isoko iracyaterwa ahanini n’ibitumizwa mu mahanga.

Ugereranije na pani, fibre yububiko buciriritse hamwe na bande, OSB ifite coefficente yo kwagura umurongo muke, ihagaze neza, ibikoresho bimwe hamwe nimbaraga nini zifata; Kuberako igice cyacyo gitunganijwe muburyo runaka, imbaraga zacyo zigihe kirekire zunamye ziruta iz'inyuma, bityo rero irashobora gukoreshwa nkibikoresho byubatswe hamwe nabanyamuryango bitwaje imitwaro. Byongeye kandi, irashobora kubonwa, kumusenyi, gutegurwa, gucukura, imisumari no gutangwa nkibiti, kandi nibikoresho byiza byubaka inyubako, imitako yimbere no gukora ibikoresho. Ikibi ni uko umubyimba uhagaze neza, ahanini kubera ko ingano yikintu itandukanye, kandi icyerekezo nu mpande zingingo mugikorwa cya kaburimbo ntibishobora kuba bitambitse rwose kandi bihuje, bizakora igipimo cyinshi cyinshi, gifite a Ingaruka zimwe kumubyimba uhamye.

Ibyiza byo gusohora imyuka mibi ya formaldehyde byemewe nisoko nkikibaho cyiza cyane gishingiye ku biti mu gihe kiri imbere, kandi OSB ifite umwanya mugari wo gukoresha no kwiteza imbere. Isoko ririmo gushakisha inyungu zo kurekurwa kubuntu, bishobora gukoreshwa cyane cyane: amagorofa, inkuta nigisenge, I-beam, imbaho ​​zo kwigunga zubatswe, udusanduku twapakiye, ibicuruzwa pallets hamwe nagasanduku ko kubikamo, ububiko bwibicuruzwa, desktop yinganda, igiti gikomeye intangiriro, ikirere cyo mu kirere na guardrail, imbaho ​​zometseho urukuta, ibishushanyo mbonera bya beto yububiko, hasi ya kontineri, inzu yo gukiniraho, nibindi.

Nyuma yo gutunganywa, izasimbuza ikibaho, pani, pani, inyubako zubaka, ikibaho kitagira umuriro, ikibaho cyiza na MDF. Umurongo uri hagati yimbaho ​​zikomeye na keel, cyangwa ibikoresho fatizo bikozwe mubiti byubatswe. Isahani yububiko bwibikoresho byo mu gikoni. Ikibaho cyimbere, ikibaho cyimbere, ikibaho cyubushyuhe, ikibaho gikurura amajwi, igisenge hamwe nurukuta rwo kubaka. Kugumana isahani, gukora umwobo, isahani fatizo, nibindi byo kubaka. Ubuso bwa OSB bumaze kwomekwa kuruhande rumwe, burashobora gukoreshwa kububaho busanzwe, icyapa gikurura, agasanduku, kugabana abaminisitiri, ikibaho hasi, ikibaho cyo kuryama, nibindi byo gukora ibikoresho.
