I-OSB (i-OrientedStrandBoard) iwuhlobo lokhuni olubunjiwe olufana nebhodi lezinhlayiyana, ngokwengeza izingqimba zemicu yokhuni (ama-flakes) ngendlela ethile eyakha i-binder bese icindezela ukhuni.
Yasungulwa ngo-1963 ngu-Armin Elmendorf waseCalifornia. I-OSB ingaba nendawo emangelengele futhi ehlukahlukene, enemicu engayodwana cishe engu-2.5 cm x 15 cm (1.0 x 5.9 in) ebekwe ngokungalingani phakathi kwenye, futhi ezinhlotsheni ezihlukahlukene nogqinsi.

Inhloso ye-OSB

I-OSB iyimpahla enezici ezinhle zomshini, okuyenza ifaneleke ikakhulukazi izinhlelo ezithwala umthwalo ekwakhiweni.
Manje isidume kakhulu kuneplywood, ibalwa ku-66% wemakethe yamaphaneli esakhiwo. Izinto ezisetshenziswa kakhulu zifana nokushelela izindonga, phansi kanye nophahla.
Ngezinhlelo zokusebenza zodonga lwangaphandle, amaphaneli angenziwa nge-laminated nge-radiant barrier ohlangothini olulodwa; lokhu kwenza ukufakwa kube lula futhi kuthuthukisa ukusebenza kwamandla emvilophu yokwakha. I-OSB nayo isetshenziswa ekukhiqizeni ifenisha.

Ukwenziwa kwamabhodi we-OSB

Izinhlobo zezinhlayiya zokunamathisela ezisetshenziswa yi-OSB zifaka: i-urea-formaldehyde (uhlobo lwe-OSB 1, olungenasakhiwo, olungenawo amanzi); i-isocyanate-based adhesives (noma i-PMDI polymethylene diphenyl diisocyanate-based) ezindaweni zangaphakathi ezine-melamine-urea-formaldehyde noma i-phenol-formaldehyde Resin glue ebusweni (uhlobo lwe-OSB 2, lwesakhiwo, ukuvimbela amanzi ngaphezulu); i-phenolic resin (uhlobo lwe-OSB 3 no-4, uhlobo lwesakhiwo, lwezindawo ezimanzi nezingaphandle).

Izendlalelo zakhiwa ngokuhlehla ukhuni lube yimicu ehluzwayo bese iqondiswa ebhandeni noma emshinini wocingo. Ama-cushions akhiqizwa emgqeni wokubumba. Ama-slats okhuni ongqimba lwangaphandle ahambisana ne-axis yamandla yamaphaneli, kuyilapho ungqimba lwangaphakathi luqondile. Inani lezendlalelo ezibekwe ngokwengxenye lincike ebukhulu bephaneli, kodwa linqunyelwe impahla efakwe endaweni yokukhiqiza. Ugqinsi lwezendlalelo ezingazodwana lungaphinda luhluke ukuze lunikeze ukujiya okuhlukile kwephaneli eqediwe (imvamisa, isendlalelo esingu-15 cm (5.9 in) sizokhipha ugqinsi lwephaneli engu-15 mm (0.59 in). Umata ufakwa emshinini wokunyathelisa oshisayo ukuze ucindezele amashidi futhi uwabophe ngokusebenza ngokufudumele futhi uphulukise inhlaka eboshwe emashidini. Amaphaneli angawodwana abe esesikwa kusuka kumata kuya kusayizi ophelile. Iningi le-OSB yomhlaba likhiqizwa ezindaweni ezinkulu zokukhiqiza e-United States naseCanada.

Imikhiqizo Ehlobene

Izinto ezingaphandle kokhuni zisetshenziselwe ukukhiqiza imikhiqizo efana ne-OSB. Ibhodi lotshani lesakhiwo esimakiwe liyibhodi lobunjiniyela elenziwe ngokuhlukanisa utshani, ukwengeza okunamathelayo kwe-P-MDI, nokucindezela okushisayo ungqimba lotshani ohlangothini oluthile. I-Particleboard nayo ingenziwa nge-bagasse.
