OSB.
Yahimbwe mu 1963 na Armin Elmendorf wo muri Californiya. OSB irashobora kuba ifite ubuso butandukanijwe kandi butandukanye, hamwe numurongo wihariye hafi cm 2,5 x x cm 15 (1.0 x 5.9 muri) ushyizwe hamwe, kandi mubwoko butandukanye nubunini.

Intego ya OSB

OSB ni ibikoresho bifite imiterere yubukanishi, bituma bikenerwa cyane cyane mubikorwa bitwara imitwaro mubwubatsi.
Ubu irazwi cyane kuruta pani, ihwanye na 66% yisoko ryimiterere. Ibikoreshwa cyane ni nko gukata inkuta, hasi no hejuru yinzu.
Kubikorwa byurukuta rwinyuma, panne irashobora kumurikirwa hamwe na bariyeri irabagirana kuruhande rumwe; ibi byoroshya kwishyiriraho kandi bitezimbere ingufu zamabahasha yinyubako. OSB nayo ikoreshwa mugukora ibikoresho.

Gukora Ubuyobozi bwa OSB

Ubwoko bwibisigarira bifata bikoreshwa na OSB birimo: urea-formaldehyde (ubwoko bwa OSB 1, butubatswe, butagira amazi); ibishingwe bishingiye kuri isocyanate (cyangwa PMDI polymethylene diphenyl diisocyanate ishingiye) mubice byimbere hamwe na melamine-urea-formaldehyde cyangwa fenol-formaldehyde Resin glue hejuru (OSB ubwoko bwa 2, imiterere, itangiza amazi); resin ya fenolike (ubwoko bwa OSB 3 na 4, ubwoko bwimiterere, kubidukikije bitose no hanze).

Ibice byakozwe mugutemagura inkwi mumirongo igenzurwa hanyuma ikerekanwa kumukandara cyangwa inshundura. Imyenda ikorerwa kumurongo. Ibiti byimbaho ​​byimbaho ​​byo hanze byahujwe nimbaraga zomwanya wibibaho, mugihe imbere imbere harahagaritse. Umubare wibice byashyizwe biterwa nubunini bwikibaho, ariko bigarukira kubikoresho byashyizwe ahakorerwa. Umubyimba wububiko bwa buriwese urashobora kandi gutandukana kugirango utange ubunini butandukanye bwuzuye (mubisanzwe, cm 15 (5.9 in)) bizatanga mm 15 (0.59 in) uburebure bwikibaho). Matasi ishyirwa mumashini ashyushye kugirango uhagarike impapuro hanyuma uyihambire mugukoresha ubushyuhe no gukiza ibisigazwa byashizwe kumpapuro. Ikibaho cyihariye noneho gicibwa kuva kumatiku kugeza mubunini bwuzuye. Hafi ya OSB kwisi yose ikorerwa mubikorwa binini byo gukora muri Amerika na Kanada.

Ibicuruzwa bifitanye isano

Ibikoresho bitari ibiti byakoreshejwe mu gukora ibicuruzwa bisa na OSB. Icyerekezo cyimiterere yicyatsi ni ikibaho cyubwubatsi gikozwe mukugabanya ibyatsi, ukongeramo P-MDI, hamwe no gushyushya gukanda ibyatsi mubyerekezo runaka. Particleboard irashobora kandi gukorwa muri bagasse.
