I-OSB (i-OrientedStrandBoard) luhlobo lwenkuni eyenziwe ngobunjineli efana nebhodi yamasuntswana, ngokongeza iileya zemisonto yeplanga (iiflekhi) kwi-orientation ethile eyenza i-binder kwaye emva koko icinezele iinkuni.
Yasungulwa ngo-1963 nguArmin Elmendorf waseCalifornia. I-OSB inokuba nomphezulu orhabaxa kunye nokwahluka-hlukeneyo, kunye nemicu eyodwa malunga ne-2.5 cm x 15 cm (1.0 x 5.9 ngaphakathi) ebekwe ngokungalinganiyo enye nenye, kwaye kwiindidi ezahlukeneyo kunye nobukhulu.

Injongo ye-OSB

I-OSB yimathiriyeli eneempawu ezilungileyo zoomatshini, okwenza ukuba ifaneleke ngokukodwa kwizicelo zokuthwala umthwalo ekwakhiweni.
Ngoku idume kakhulu kuneplywood, ibalwa kwi-66% yemarike yephaneli yolwakhiwo. Olona setyenziso luxhaphakileyo lufana nokushela iindonga, imigangatho kunye nophahla.
Ukusetyenziswa kweendonga zangaphandle, iipaneli zinokuthi zenziwe nge-laminated kunye nomqobo okhanyayo kwicala elinye; oku kwenza kube lula ukufakela kunye nokuphucula ukusebenza kwamandla kwimvulophu yokwakha. I-OSB ikwasetyenziswa kwimveliso yefenitshala.

Ukwenziwa kweebhodi ze-OSB

Iindidi ze-resin zokubambelela ezisetyenziswe yi-OSB ziquka: i-urea-formaldehyde (uhlobo lwe-OSB 1, olungelulo, olungenawo amanzi); i-isocyanate-based adhesives (okanye i-PMDI polymethylene diphenyl diisocyanate-based) kwiindawo zangaphakathi kunye ne-melamine-urea-formaldehyde okanye i-phenol-formaldehyde Resin glue phezu komhlaba (i-OSB uhlobo lwe-2, i-structural, i-surface waterproofing); i-phenolic resin (uhlobo lwe-OSB 3 kunye ne-4, uhlobo lwesakhiwo, kwiindawo ezimanzi nangaphandle).

Iimaleko zenziwe ngokukrazula iinkuni zibe yimicu ehluzwayo kwaye ijongiswe kwibhanti okanye i-wire mesh. I-cushions yenziwa kumgca wokubumba. I-slats yokhuni yomgangatho wangaphandle ihambelana ne-axis yamandla yeepaneli, ngelixa i-layer yangaphakathi imile. Inani leengqimba ezibekwe kuxhomekeke kwinxalenye yobukhulu bepaneli, kodwa inqunyelwe yizixhobo ezifakwe kwindawo yokuvelisa. Ubukhulu bomaleko ohlukeneyo bunokwahluka ukunika ubungqingqwa bephaneli obugqityiweyo obahlukeneyo (ngokuqhelekileyo, umaleko we-15 cm (5.9 in) uya kunika i-15 mm (0.59 in) ubukhulu bephaneli). I-mat ifakwe kwi-press eshushu ukuze icinezele amaphepha kwaye idibanise ngokuvuselela i-thermal kunye nokunyanga i-resin egqunywe kumaphepha. Iiphaneli zomntu ngamnye zisikwa ukusuka kwimethi ukuya kubungakanani obugqityiweyo. Uninzi lwe-OSB yehlabathi iveliswa kwiindawo ezinkulu zemveliso eMelika naseCanada.

Iimveliso ezinxulumeneyo

Izinto ezingaphandle kweenkuni zisetyenzisiwe ukuvelisa iimveliso ezifana ne-OSB. Oriented isakhiwo istraw ibhodi ibhodi yobunjineli eyenziwe ngokwahlula istraw, ukongeza P-MDI incamathiso, kwaye eshushu ngokucinezela umaleko istraw kwicala elithile. I-particleboard ingenziwa kwakhona kwi-bagasse.
