Kev paub txog kev tswj hwm thiab tiv thaiv koj OSB yuav ua li cas txuag koj lub sijhawm, nyiaj txiag, thiab mob taub hau hauv kab, ua qhov no tsim nyog nyeem rau txhua tus neeg koom nrog hauv kev tsim kho lossis txhim kho tsev.
Dab tsi yog OSB thiab vim li cas nws thiaj li yog ib qho khoom siv hauv tsev nrov?
Oriented strand board, lossis OSB, yog cov khoom siv ntoo tsim los ntawm cov txheej txheem ntawm cov ntoo - feem ntau aspen, ntoo thuv, los yog fir - hauv kev taw qhia tshwj xeeb thiab compressing lawv ua ke nrog cov nplaum thiab cov resin. Cov txheej txheem no tsim lub vaj huam sib luag muaj zog, khoom siv dav siv hauv kev tsim kho. Xav txog nws zoo li high-tech version ntawm plywood, tab sis es tsis txhob nyias cov nplooj ntawv ntawm veneer, nws siv loj, duab plaub strands. Nws cov koob meej tshwm sim los ntawm ntau qhov txiaj ntsig tseem ceeb. Ua ntej, OSB feem ntau siv nyiaj ntau dua li cov plywood, ua rau nws yog qhov kev xaiv zoo rau cov haujlwm loj. Qhov thib ob, nws khav theeb qhov ntev thiab qhov tsis muaj qhov tsawg dua piv rau cov ntoo ntoo, ua rau kev ua tau zoo dua. Thaum kawg, OSB muaj lub zog shear zoo heev, ua rau nws zoo tagnrho rau kev siv cov txheej txheem xws li ru tsev sheathing thiab phab ntsa sheathing. Raws li lub Hoobkas tshwj xeeb hauv cov khoom siv ntoo, suav nrog cov khoom zoo LVL Ntoo thiab cov khoom siv plywood, peb nkag siab qhov tseem ceeb ntawm kev muaj cov khoom siv tau zoo thiab muaj txiaj ntsig zoo li OSB muaj nyob hauv khw.
Puas yog OSB Inherently Waterproof?
Tsis yog, txawm tias nws lub zog thiab ntau yam, tus qauv OSB yogtsis waterproof. Qhov no yog lub ntsiab lus tseem ceeb kom nkag siab. Thaum cov resin thiab adhesives siv nyob rau hauv nws manufacturing muab ib tug degree ntawm noo noo tsis kam, OSB tseem yog ib tug ntoo khoom thiab inherently ntxeem tau. Thaum OSB ntub dej, cov ntoo fibers yuav nqus dej noo, ua rau lub vaj huam sib luag o. Xav txog daim txhuam cev - nws nqus dej. Qhov o tuaj yeem ua rau ntau yam teeb meem, suav nrog kev poob ntawm cov qauv kev ntseeg siab, delamination (cov txheej txheem sib cais), thiab muaj peev xwm ua rau pwm thiab pwm loj hlob. Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm cov dej-resistant thiab waterproof. Qee cov ntaub ntawv raug tsim los tiv thaiv lub sijhawm luv luv ntawm kev ya raws, tab sis ntev los yog kev sib cuag nrog dej ntau dhau yuav ua rau muaj kev puas tsuaj. Ib yam li pebzaj duab xis ntsib plywood, uas muaj lub ntsej muag ruaj khov los tiv thaiv cov dej noo, tus qauv OSB tsis muaj kev tiv thaiv qib no.
Los nag cuam tshuam li cas rau OSB Roof Sheathing tshwj xeeb?
Thaum OSB siv los ua lub ru tsev sheathing, nws tau ncaj qha mus rau cov ntsiab lus, suav nrog los nag. Los nag hnyav, tshwj xeeb tshaj yog tias ntev, tuaj yeem ua rau OSB panels saturate. Cov npoo ntawm cov vaj huam sib luag tshwj xeeb yog qhov yooj yim rau absorbing noo noo. Yog tias lub ru tsev tsis zoo nrog cov khoom thaiv dej, xws li cov ntawv tar lossis cov khoom siv hluavtaws, thiab tom qab ntawd ua tiav nrog shingles tam sim ntawd, OSB tuaj yeem muaj kev nqus dej tseem ceeb. Qhov no yog qhov tseeb tshwj xeeb tshaj yog thaum lub sij hawm tsim kho ua ntej lub ru tsev raug kaw tag nrho. Kev rov ua dua ntawm kev ntub dej thiab ziab tawm tuaj yeem ua rau OSB tsis muaj zog thaum lub sijhawm, uas tuaj yeem ua rau warping lossis sagging ntawm lub ru tsev lawj. Los ntawm peb cov kev paub dhau los hauv kev muab cov txheej txheem plywood rau kev siv lub vov tsev, peb paub tias thaum OSB muaj lub hauv paus ruaj khov, nws yuav tsum muaj kev tiv thaiv raws sijhawm los ntawm nag los tswj nws cov kev ua tau zoo.
Yuav ua li cas thaum OSB ntub dej? Nkag siab qhov o thiab puas.
Qhov laj thawj tseem ceeb ntawm OSB tau ntub yog o. Raws li cov ntoo strands nqus noo noo, lawv nthuav.
