Moisture resistant OSB plywood yog ib qho ntawm cov khoom tsim tshiab hauv kev lag luam ntoo. Cov khoom no yog tshwj xeeb nyob rau hauv nws versatility - nws yog dav siv nyob rau hauv kev tsim kho. Cov plywood no yog siv rau hauv kev tsim vaj tsev ntoo thiab thav duab, cov tsev los ntawm SIP panels, rau kev npaj subfloors.
OSB board structure
Cov khoom npe muaj npe tsuas yog cov khoom xyaw ntuj - ntoo chips thiab kua nplaum, uas yog raws li cov khoom siv ntuj tsim. Nrog kev pab los ntawm cov cuab yeej tshwj xeeb, cov chips tau muab tso rau hauv qee cov lus qhia, uas muab cov laug cam tsim nyog thiab elasticity. Xws li kev ua haujlwm siab ua rau cov khoom siv no muaj ntau yam.
Cov khoom siv ua kom noo noo plywood
OSB plywood yog ib qho kev taw qhia strand board. Rau nws cov ntau lawm, ntoo ntawm coniferous thiab qee hom deciduous, feem ntau cov ntoo loj hlob sai, feem ntau yog siv. Qhov kev xaiv no feem ntau cuam tshuam nrog ib puag ncig - cov neeg tsim khoom sim tsis ua phem rau xwm thiab tsis cuam tshuam nws qhov nyiaj tshuav.
OSB ntau lawm technology
Kev tsim cov khoom siv no yog ua los ntawm ntau theem. Cov no suav nrog:
- Kev xaiv ntoo kom haum.
- Nyob zoo ib tsoom phooj ywg.
- Kev.
- nias thiab ua tiav daim phaj.
Cia peb xav txog txhua yam ntawm lawv kom ntxaws ntxiv. Yog li ntawd, nyob rau hauv lub sorting theem, tsis ua hauj lwm, nyias ntoo yog xaiv. Lub cev yuav tsum tau saws kom qhov tshwm sim yog qhov khoob ntawm qhov ntev me me, tom qab ntawd lawv dhau los ntawm cov cuab yeej tshwj xeeb uas hloov cov blanks mus rau hauv ib pawg ntawm chips. Los ntawm txoj kev, rau qhov no, chips ntawm ntau qhov sib txawv yog siv. Tom ntej no, cov ntoo chips tau raug xa mus rau cov bunkers tshwj xeeb, qhov chaw uas lawv tau qhuav kom huv si, tom qab ntawd cov chips tau txheeb raws qhov loj me.
Nyob rau theem thib ob, qhov kev sib xyaw ua ke tshwm sim - tshwj xeeb phenolic lossis isocyanate resins ntxiv rau cov khoom siv. Qhov no yog qhov tsim nyog rau OSB plywood kom muaj lub zog sab hauv, rigidity thiab tsim nyog ya raws. Cov sib tov nkag mus rau hauv ib lub nruas tshwj xeeb, uas kuj tau pub nrog ib tug binder thiab paraffins.
Tom ntej yog theem molding. Cov txheej txheem no yog ua los ntawm kev siv lub chaw nres tsheb tshwj xeeb nrog lub siab rollers, nrog rau cov hlau nplaum thiab cov nplais. Cov hlau nplaum pab tshem tawm ntau lub cev txawv teb chaws thiab cov khoom ntawm lub phaj yav tom ntej. Nyob rau theem no, cov khoom yuav roughly chipped. Cov txheej saum toj kawg nkaus yog muab tso rau ntawm qhov ntev ntawm cov slab, thiab hla txheej sab hauv.
Tom qab ntawd, tom qab OSB plywood tau tsim, nws mus hauv qab xovxwm. nyob rau hauv siabthiab kub kub, cov ntaub pua plag ntawm shavings yog ho compacted. Cov txheej txheem no yog ua los ntawm kev siv cov hlua steel pre-lubricated nrog cov roj thermal tshwj xeeb. Lub zog quab yuam feem ntau yog 5 N / mm².
Ntse
Cov khoom siv hauv tsev no muaj ntau yam tshwj xeeb. Niaj hnub no, tsis muaj ib yam ntawm cov khoom ntoo uas twb muaj lawm nyob rau hauv lub lag luam muaj xws li qualities.
Cov paib tiv thaiv dej yog cov thev naus laus zis heev. Lawv yooj yim heev los ua haujlwm nrog cov cuab yeej ua haujlwm ntoo.
Cov khoom kuj muaj peev xwm tuav tau siab. Raws li ib feem ntawm hom plywood no, chips loj yog siv. Xws li canvases zoo kawg nkaus tuav cov ntsia hlau thiab lwm yam fasteners. Ntau tus kws ua haujlwm tsav tsheb ntsia hlau rau hauv plywood ntawm qhov deb ntawm 6 hli lossis ntau dua los ntawm ntug - nws tsis tawg.
Ntxiv rau, cov khoom siv hauv tsev no tau zoo los ntawm cov neeg koom nrog cov nplaum, raug rau kev sib tsoo ua ntej ntawm qhov chaw. Tsis tas li ntawd, lub phaj tuaj yeem pleev xim nrog txhua yam xim. Los ntawm txoj kev, yog tias plywood yuav siv sab nraum zoov, cov kws tshaj lij pom zoo kho nws qhov chaw nrog cov tshuaj tiv thaiv uas yuav tiv thaiv tsob ntoo kom ntseeg tau los ntawm cov teeb meem ntawm huab cua.
Slabs muaj lub cev zoo. Yog li, lawv qhov tseem ceeb hloov pauv hauv qhov tseem ceeb me me, nyob ntawm cov chaw tsim khoom tshwj xeeb (tus nqi nruab nrab ntawm cov nqi ceev yog 640 kg / mg /
OSB kev ua haujlwm
Raws li rau qib ntawm kev ya raws, OSB plywood yog cov khoom ntoo uas tsis hnov mob rau cov av noo thiab kub hloov pauv. Lub phaj tseem ua raws li North American tus qauv - raws li nws, cov khoom yuav tsum tsis txhob hloov nws cov yam ntxwv geometric yog tias nws ua haujlwm ntawm qhov kub ntawm + 20 ° C thiab av noo ntawm 65%..
Oriented strand board muaj kev nyab xeeb hluav taws kub. Cov ntaub ntawv piav qhia tau raug sim hauv cov chaw kuaj mob ywj pheej, uas tau lees paub los ntawm cov kev pabcuam kev nyab xeeb hluav taws. OSB board (plywood, raws li nws tseem hu ua) tau dhau tag nrho cov kev ntsuam xyuas rau hluav taws kub thiab qhov ceev ntawm cov nplaim taws yuav kis tau los ntawm nws.
Kev faib tawm raws lub hom phiaj
Hnub no, ob peb hom ntawm cov phiaj no muaj nyob rau hauv lub khw muag khoom. Lawv txawv ntawm lub hom phiaj thiab cov khoom. Nyob rau hauv tag nrho muaj plaub hom plywood.
OSB-1 yog lub npe pib. Cov khoom siv no muaj cov qauv tsis tshua muaj siab. Raws li kev txheeb xyuas, lub ntsiab drawback ntawm cov khoom no yog ua tiav tsis muaj tsawg kawg yog ib co ya raws. Plywood ntawm hom no feem ntau yog siv los ua cov rooj tog zaum.
OSB-2 twb muaj zog dua thiab cov yam ntxwv ntom ntom. Txawm li cas los xij, raws li cov kws tshaj lij, qhov no tseem tsis yog cov khoom siv tiv thaiv dej noo. Cov phaj no siv tau yuav luag txhua qhov chaw uas nws yuav tsis raug dej.
OSB-3 plywood twb yog cov khoom siv dej tsis zoo thiab yog ib qho nrov tshaj plaws ntawmcov neeg siv khoom ntawm hom oriented strand boards. Qhov no plywood yog heev ruaj thiab resistant rau ya raws. Nws yog zoo meej rau cladding prefabricated ncej tsev.
Tab sis ib qho nuance tau muab zais ntawm no, uas cov tuam ntxhab thiab cov muag khoom yuav tsis qhia txog - lub phaj tau ntseeg tau tiv thaiv los ntawm ya raws nkaus xwb nyob rau hauv cov xwm txheej ntawm qhov raug luv luv. Yog tias cov khoom zoo li no tau teeb tsa raws li phab ntsa tiav hauv chav dej, tom qab ntawd ib txheej ntawm kev tiv thaiv ntxiv yuav tsum tau siv rau saum npoo. Kev puas tsuaj tuaj yeem zam tau los ntawm kev pleev xim rau saum npoo thiab siv cov dej tsis muaj pov thawj impregnation. Nyob rau hauv peb lub teb chaws, OSB-3 yog heev hlub raws li ib tug khoom rau subfloors - nyob rau hauv cov ntaub ntawv no, tsuas yog tsis muaj dab tsi zoo dua.
OSB-4 yog, raws li kev tshuaj xyuas cov neeg siv khoom, lub canvas ntawm lub zog siab heev. Ib qho ntawm nws cov yam ntxwv yog kev tiv thaiv siab tiv thaiv cov dej noo txawm tias lub sijhawm ntev raug. Muaj qhov tsis zoo, thiab nws tsuas yog ib qho - qhov no yog pes tsawg lub npe OSB plywood nqi. Nws tus nqi yog siab heev - ib daim ntawv ntsuas 1250x2500 mm, thiab qhov no yog tus qauv loj, yuav raug nqi los ntawm 500 rubles. Tus nqi nyob ntawm qhov tuab - 8 hli cov khoom raug nqi ntawm 500 rubles, 12 mm - los ntawm 680 rubles, 15 mm - los ntawm 880 rubles, 18 mm - los ntawm 980 rubles. Tab sis tus nqi kuj nyob ntawm qhov chaw tsim khoom.
OSB board qhov ntev thiab qhov hnyav
Cia pib nrog tuab. Muaj ntau ntau txoj kev xaiv rau cov phaj no, xws li ntawm 8 mus rau 25 hli. Raws li qhov ntsuas no, cov phiaj tau muab faib ua peb pawg:
- Cov ntaub ntawv nyias yog 8, 9, thiab 10 mm.
- Nruab nrab tuab yog 12mm thiab 15mm.
- Thickcanvas - 18, 22 thiab 25 mm.
Qhov hnyav ntawm daim ntawv yog ncaj qha nyob ntawm qhov tuab. Yog li, nrog lub phaj tuab ntawm 8 hli, nws qhov hnyav yuav yog li 16.6 kg. 9 hli cov khoom yuav hnyav 18.4 kg, 10 mm - 20.6 kg.
Ib qho ntawm cov yam ntxwv uas OSB plywood xaiv yog qhov ntev. Qhov tseeb, muaj ob peb. Qhov nrov tshaj plaws ntawm cov neeg yuav khoom hauv tsev yog 2440x1200 mm, tus qauv European loj yog 2500x1250 mm thiab qhov loj me me yog 2440x950 mm. Nws ntseeg tau tias cov slabs tshiab tshaj plaws yog nrov rau kev teeb tsa hauv pem teb, txawm tias txhua yam khoom siv tau zoo sib xws.
Qhov twg zoo dua: OSB lossis plywood
Rau cov neeg paub tseeb tias OSB yog ib yam tshiab thiab niaj hnub, nws tsim nyog hais tias cov laug cam tau tsim ntau xyoo dhau los. Tom qab ntawd tsis muaj plywood ntau npaum li cas ntawm kev ua lag luam li niaj hnub no, thiab OSB tau yuav vim nws yog ib qho pheej yig dua ntawm plywood.
Nyob rau hauv kev tsim cov strand board, ntuj resins yog siv, nrog rau waxes thiab boric acid. Formaldehyde yog siv los tsim cov plywood. Hais txog kev nyab xeeb, OSB yog qhov zoo dua - cov phaj no tuaj yeem siv rau hauv thaj chaw nyob. Plywood tsis haum rau qhov no, vim muaj cov tshuaj phem.
Ntxiv rau, rau cov plag tsev, piv txwv li, OSB ntawm tus qauv tsim tshwj xeeb yog siv - qhov kawg ntawm cov khoom no yog tus nplaig-thiab-groove. Qhov no yog ua tiav kom ua tiav cov khoom zoo thiab yooj yim koom nrog ntawm lawv tus kheej.
Thaum xaiv, tau kawg, nws yog ib qho tseem ceeb rau kev taw qhia nyob ntawm qhov xwm txheej tshwj xeeb. TABSISYog tias koj xaiv los ntawm tus nqi, ces OSB tseem pheej yig dua li plywood.
Tseeb tiag, txawm hais tias tus nqi ntawm cov khoom siv qis dua li qhov tau thov rau plywood, lub phaj no yuav tsum tsis txhob siv rau cov plag tsev tiav - cov tsos yuav tsis zoo nkauj hlo li. Tab sis, raws li twb tau sau tseg, nyob rau hauv qhov kev sib cav - uas yog zoo dua, plywood los yog OSB nyob rau hauv pem teb - lub tom kawg yeej tseem ceeb nyob rau hauv ib puag ncig.
OSB lossis plywood rau phab ntsa?
Plywood ua cov khoom siv rau phab ntsa tsis pom zoo los ntawm cov kws tshaj lij, vim yog txhua yam formaldehydes. Los ntawm saum toj no, ob qho tib si cov ntaub ntawv tuaj yeem coated nrog ntau yam tshuaj tiv thaiv los yog varnishes. Cov slab zoo dua thiab nrawm dua rau kev sib tsoo, nws kuj zam cov primer zoo dua.
Yog li, nws yog qhov tseeb tias nyob rau hauv ntau lub sijhawm koj yuav tsum siv cov khoom sib txawv uas tsim nyog rau ib txoj haujlwm tshwj xeeb.
