Kwiminyaka yakutshanje, ngokukhula kolwazi lwendalo esingqongileyo kunye nemfuno yezinto ezizinzileyo kushishino lokwakha, i-OSB (Ibhodi ye-Oriented Strand), imathiriyeli entsha yokwakha ehambelana nokusingqongileyo, ibe lukhetho oludumileyo kwimarike yamazwe ngamazwe. Inkqubo yemveliso ekhethekileyo kunye nokusebenza okugqwesileyo kubonisa amandla ayo amakhulu kwimveliso yefenitshala, izakhiwo zokwakha, ukuhombisa kwangaphakathi, kunye namanye amacandelo.
I-OSB yavela kuMntla Melika ngeminyaka yoo-1970. Yenziwe ngamaplanga amancinci -enziwe ngamaplanga, amaplanga amancinci, okanye iintsalela zokwenziwa komthi, i-OSB iveliswa ngenkqubo yendlela yokuqondisa kunye noxinzelelo oluphezulu{3}}lobushushu. Xa ithelekiswa neplywood yemveli okanye i-MDF, i-OSB inika uzinzo olukhulu lolwakhiwo, aphuculwe kakhulu amandla okugoba kunye nomthwalo{5}}umthamo wokuthwala, ukufunxwa kwamanzi aphantsi, kunye nokumelana nokufuma okugqwesileyo. Ezi mpawu zenza ukuba zifaneleke ngokukodwa ukwakhiwa kwezicelo kwiindawo ezifumileyo, ezifana nomgangatho, iipaneli zodonga, kunye nezakhiwo zophahla.
Ukusebenza kokusingqongileyo kwe-OSB kugqame ngokukodwa. Izinto zokuncamathelisa ezisetyenziswa kwinkqubo yayo yokuvelisa ikakhulu i-formaldehyde -esimahla okanye ephantsi{2}}i-formaldehyde resins, inciphisa ngokubonakalayo ukukhutshwa kwe-formaldehyde kunye nokuhlangabezana nemigangatho yokusingqongileyo yamazwe ngamazwe, efana ne-E1 yaseYurophu kunye nomgangatho ongqongqo we-CARB we-P2. Olu phawu lwenza kube yinto ekhethiweyo yezakhiwo eziluhlaza kunye nezindlu eziphilileyo. Ngaphaya koko, imveliso ye-OSB isebenzisa ngokupheleleyo izixhobo zokhuni, inciphisa uxinzelelo lokugawulwa kwamahlathi, kwaye ihambelane neendlela zophuhliso oluzinzileyo lwehlabathi.
Ngokwembono yemarike, imfuno ye-OSB ikhula ngokukhawuleza. Kwiimarike zaseYurophu naseMelika, isetyenziswa ngokubanzi kwinkxaso yolwakhiwo kwizakhiwo zokuhlala kunye nezorhwebo kwaye ifunwa kakhulu ekuhombiseni ikhaya ngenxa yendalo yayo, imbonakalo yerustic. Kwimarike yaseAsia, kunye nemfuno ekhulayo yezinto ezihambelana nokusingqongileyo kwishishini lokwakha, ukusetyenziswa kwe-OSB kuyanda ngokuthe ngcembe, ngakumbi kwizakhiwo ezenziwe ngaphambili kunye nefenitshala yesiko.
Kwixesha elizayo, ngenkqubela phambili yetekhnoloji kunye neenkqubo zokuvelisa eziphuculweyo, ukusebenza kwe-OSB kuya kwandiswa ngakumbi, kwaye iimeko zokusetyenziswa kwayo ziya kuhluka ngakumbi. Kubasebenzi borhwebo lwangaphandle, i-OSB ayilocandelo lemveliso kuphela elinamandla amakhulu, kodwa ikwayibhulorho ebalulekileyo edibanisa iindlela zokusingqongileyo kunye nemfuno yemarike.
