Oriented Strand Board (OSB) yog ib yam ntawm cov txheej txheem board ua los ntawm lub tiaj tiaj nqaim thiab ntev shavings uas tau qhuav, tshuaj xyuas, siv nrog cov nplaum thiab cov khoom ntxiv, thiab kub-nias tom qab kev taw qhia paving. Nws muaj lub zog siab vim nws yog ua los ntawm ntau txheej ntawm ntoo chips. Hauv Nyij Pooj thiab Tebchaws Europe thiab Tebchaws Meskas, OSB raug suav hais tias yog qhov kev loj hlob sai tshaj plaws, feem ntau cog lus thiab thev naus laus zis loj.
Tam sim no, kev siv OSB hauv Tebchaws Meskas tau suav txog ib nrab ntawm tag nrho kev siv cov neeg tsim vaj huam sib luag, thiab tau maj mam hloov plywood, veneer thiab lwm cov txiv neej ua vaj huam sib luag hauv ntau qhov kev siv.

OSB Board cov qauv tsim

Nws yog ib hom kev taw qhia cov phaj ua los ntawm cov ntoo me me, nyias ntoo thiab ntoo, ua tiav rau hauv 40-100 hli ntev, 5-20 hli dav thiab 0.3-0.7 hli tuab flakes los ntawm cov cuab yeej tshwj xeeb, thiab ua tiav los ntawm deoiling, ziab, gluing, directional paving, kub nias thiab lwm yam txheej txheem. Nws cov txheej txheej flakes yog teem rau longitudinally, thiab cov tub ntxhais txheej flakes yog teem transversely. Qhov kev npaj crisscross no reorganizes ntoo kev ntxhib los mos qauv, kiag li tshem tawm qhov cuam tshuam ntawm ntoo sab hauv kev nyuaj siab ntawm kev ua, thiab ua rau nws yooj yim heev rau txheej txheem thiab ya raws-pov thawj.

Vim tias OSB muaj cov qauv kev taw qhia, tsis muaj cov pob qij txha, cov kab nrib pleb, cov kab nrib pleb, zoo tag nrho cov kev sib raug zoo, thiab kev sib koom ua ke siab, ob qho tib si hauv nruab nrab thiab ntug ntawm OSB muaj tus ntsia thawv super tuav lub peev xwm uas cov hlau tsis sib xws. Relying ntawm lub teb chaws Yelemees, lub nceeg vaj ntawm tshuaj lom neeg kev lag luam, cov nplaum siv los ntawm European phaj yeej ib txwm tuav txoj hauj lwm nyob rau hauv lub ntiaj teb no. Lub formaldehyde emission ntawm cov khoom tiav ua raws li cov qauv European siab tshaj (European E1 tus qauv), uas tuaj yeem sib piv nrog cov ntoo ntuj.

Qhov zoo thiab cov yam ntxwv ntawm OSB Board

1. Nws muaj lub cev thiab cov khoom siv kho tshuab siab, cov qauv compact thiab lub zog siab.
2. Nws muaj peb yam ntxwv ntawm deformation kuj, tev tsis kam thiab warpage kuj.
3. Anti-corrosion, mothproof, deformation resistant, thiab muaj zog nplaim retardant.
4. Ua kom tiav cov dej tsis zoo, tuaj yeem raug mus tas li rau ib puag ncig ntuj thiab ntub dej.
5. Formaldehyde emission yog tsawg heev, uas yog ib tug tiag tiag ntsuab ib puag ncig tiv thaiv khoom.
6. Cov ntsia hlau ruaj khov, yooj yim rau pom, ntsia thawv, laum, qhov, dav hlau, ntaub ntawv lossis xuab zeb.
7. Nws muaj cov rwb thaiv tsev zoo heev, lub suab rwb thaiv tsev zoo thiab cov xim zoo nkauj.

OSB lub hom phiaj kev ua haujlwm
OSB muaj kev ruaj ntseg zoo thiab siab ntsia hlau tuav quab yuam. Nws cov ntaub ntawv raw yog cov ntoo softwood, me-inch hardwood, ceev-loj hlob thinning ntoo, thiab lwm yam., xws li eucalyptus, fir, poplar thinning ntoo, thiab lwm yam., uas muaj ntau qhov chaw thiab tuaj yeem tsim rau hauv cov vaj huam sib luag loj (xws li. raws li 8 × 32 ko taw lossis 12 × 24 ko taw). Cov txheej txheem tsim khoom yog tsuas yog kom qhuav, kua nplaum, taw qhia thiab kub-nias cov shavings nrog qee cov duab geometric (feem ntau yog 50 hli - 80 hli ntev, 5 hli - 20 hli dav, thiab 0.45 hli - 0.6 hli tuab). Cov txheej txheem nyuaj yog siab, thiab cov cuab yeej siv peev nyiaj kuj tseem loj, feem ntau yog rau cov khoom siv txawv teb chaws, feem ntau rau ob peb billion lossis ntau dua. Tam sim no, Tuam Tshoj tus "OSB" kev tsim tshuab thiab cov cuab yeej tsim khoom muaj peev xwm nyob deb dhau ntawm North America thiab Europe. Tam sim no, lub ntsiab "OSB" hauv kev ua lag luam tseem yog nyob ntawm kev xa khoom.

Piv nrog plywood, nruab nrab-qhov ntom ntom fiberboard thiab blockboard, OSB muaj cov kab sib txuas qis qis, kev ruaj ntseg zoo, cov khoom siv sib xws thiab cov ntsia hlau siab tuav; Vim hais tias nws cov particle yog teem nyob rau hauv ib tug tej yam kev taw qhia, nws longitudinal dabtsi yog khoov lub zog yog ntau dua li ntawm lub transverse, yog li nws yuav siv tau raws li cov khoom siv thiab load-bearing tswv cuab. Tsis tas li ntawd, nws tuaj yeem raug sawed, sanded, npaj, drilled, nailed thiab ntaub ntawv zoo li ntoo, thiab yog cov khoom siv zoo rau kev tsim vaj tsev, kho kom zoo nkauj sab hauv thiab tsim rooj tog. Qhov tsis zoo yog tias cov thickness ruaj khov tsis zoo, feem ntau yog vim qhov loj ntawm cov khoom sib txawv, thiab cov kev taw qhia thiab lub kaum sab xis ntawm cov khoom hauv cov txheej txheem paving tsis tuaj yeem ua tiav kab rov tav thiab zoo ib yam, uas yuav ua rau qee qhov ceev gradient, uas muaj qhov sib txawv. tej yam cuam tshuam rau lub thickness stability.

Qhov kom zoo dua ntawm formaldehyde emissions tsawg yog txais los ntawm kev ua lag luam raws li kev cog lus ntoo zoo tshaj plaws nyob rau yav tom ntej, thiab OSB muaj qhov dav dav rau kev siv thiab kev loj hlob. Kev ua lag luam tab tom nrhiav kom zoo dua ntawm formaldehyde pub dawb, uas tuaj yeem siv tau hauv: cov plag tsev, phab ntsa thiab ru tsev, I-beams, cov khoom siv cais tawm, cov thawv ntim khoom, cov khoom pallets thiab cov thawv ntim khoom, cov khoom txee, cov khoom lag luam, hardwood floor core, cua baffle thiab guardrail, hniav phab ntsa panels, precast vaj pob zeb molding, thawv pem teb, bowling alley, thiab lwm yam.

Tom qab ua tiav, nws yuav hloov blockboard, plywood, plywood, tsev formwork, fireproof board, hniav board thiab MDF. Lub liner nruab nrab ntawm cov khoom ntoo hauv pem teb thiab keel, los yog cov khoom siv hauv paus ua los ntawm cov ntoo hauv pem teb. Cov qauv phaj ntawm cov rooj tog zaum thiab chav ua noj. Sab hauv vaj huam sib luag, vaj huam sib luag sab hauv, hluav taws xob rwb thaiv tsev board, suab-absorbing board, qab nthab thiab phab ntsa vaj huam sib luag rau lub tsev. Retaining phaj, ditch formwork, puag phaj, thiab lwm yam rau kev tsim kho. Tom qab OSB nto yog pasted rau ntawm ib sab, nws yuav siv tau rau lub tiaj board, tub rau khoom puag phaj, thawv, txee muab faib, pem teb board, txaj board, thiab lwm yam rau cov rooj tog tsim.
