Dab tsi yogOSB(OrientedStrand Bua oard)
OSByog ib yam tshiab ntawm particle board.Thaum lub sij hawm tsim ntawm particle paving, lub sab sauv thiab sab saum toj ntawm lub oriented strand particle board yog teem longitudinally nyob rau hauv lub fiber kev taw qhia ntawm mixed particle board, thaum lub core txheej particles yog teem horizontally los tsim ib tug peb-txheej txheej txheem board embryo, uas. yog ces kub nias rau hauv oriented strand particle board.Cov duab ntawm hom particle board no yuav tsum muaj qhov sib piv loj, thiab cov thickness ntawm cov khoom yog me ntsis thicker dua li ntawm cov particle boards.Cov txheej txheem ntawm kev taw qhia paving muaj xws li mechanical orientation thiab electrostatic orientation.Lub qub yog haum rau loj particle oriented paving, thaum lub tom kawg yog haum rau me me particle oriented paving.Cov kev taw qhia paving ntawm oriented particle board muab nws cov yam ntxwv ntawm siab zog nyob rau hauv ib tug tej yam kev taw qhia thiab feem ntau yog siv raws li ib tug yam ntxwv khoom siv plywood.
OSByog lub rooj tsav xwm particle ua los ntawm cov ntoo me me ntawm cov hav zoov dav dav, thiab cov ntoo loj hlob sai, thiab ua tiav los ntawm cov txheej txheem xws li deoiling, ziab, gluing, directional paving, thiab kub nias.Nws tseem hu ua oriented strand board.Nws muaj cov ntsia hlau zoo heev, nws tus kheej lub zog, ib puag ncig tus phooj ywg, thiab dej tsis kam.Tshwj xeeb yog ib puag ncig tus phooj ywg, siv ib puag ncig tus phooj ywg isocyanate adhesive (MDI) ua tus neeg sawv cev sib txuas, tsis muaj ntxhiab tsw phem, noj qab haus huv thiab zoo ib puag ncig.
Ntau lawm txheej txheem ntawmOSB
1. Kev npaj cov khoom siv raw
OSB yog ua los ntawm cov ntoo me me thiab cov ntoo loj hlob sai nrog txoj kab uas hla ntawm 8 mus rau 10 centimeters.Cov ntoo raw cov ntaub ntawv yog tev thiab impurities tshem tawm los ntawm cov cuab yeej tshwj xeeb, thiab tom qab ntawd ua tiav rau hauv cov khoom me me nrog cov duab geometric.
2. Qhuav
Lub tshuab ziab khaub ncaws rau oriented strand board feem ntau siv ib lub tshuab ziab khaub ncaws, siv cov tshuab ziab khaub ncaws nruab nrab kub.Tag nrho cov txheej txheem ziab yog muab faib ua ntej ziab, theem ziab, thiab theem sib npaug, thiab thaum kawg yuav tsum tau xyuas kom meej tias cov dej noo ntawm cov chipboard yog tswj los ntawm ib ncig ntawm 2%.
3. Particle sorting
Muaj ob hom kev sorting particle, ib qho yog siv cov txheej txheem los txheeb cov khoom raws li geometric qhov ntev los ntawm cov kab sib txawv nrog cov apertures sib txawv los yog teeb tsa, thiab lwm qhov yog los txheeb cov khoom sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov sib txawv los ntawm kev kho cov airflow ceev.
4. Kev taw qhia paving
Sib tov txheej txheej ntawm shavings nrog kua nplaum thiab npaj lawv vertically nyob rau hauv cov kev taw qhia fiber ntau, thaum lub core txheej ntawm shavings yog teem horizontally los tsim ib tug peb-txheej qauv ntawm lub board embryo.Thaum kawg, ntau txheej txheej ntawm lub rooj tsavxwm yog tsim los ntawm kev kub nias.
Yam ntxwv ntawmOSB
1. Cov khoom siv siab heev
Piv nrog rau lwm hom khoom vaj huam sib luag, taw qhia strand particle board muaj cov txiaj ntsig zoo dua, thiab kev tsim cov khoom siv strand particle board siv cov kab ntawv me me tau hloov qhov muag ntawm cov ntaub ntawv me me ntawm cov ntoo, ua rau nws muaj cov khoom siv zoo nrog siab zog thiab stability.Qhov no tsis yog tsuas yog txhim kho kev siv tus nqi ntawm cov khoom siv ntoo hauv Suav teb, tab sis kuj txo qhov siab ntawm cov khoom siv log tsis txaus.
2. Kev nyab xeeb thiab kev tiv thaiv ib puag ncig
Hauv cov txheej txheem tsim khoom, isocyanate (MDI) tau siv los hloov cov tshuaj phenolic resin adhesives, nrog rau daim ntawv thov qis thiab qis formaldehyde tso tawm, uas yuav tsis ua mob rau ib puag ncig thiab tib neeg kev noj qab haus huv.Nws yog ib qho kev nyab xeeb thiab ib puag ncig tus phooj ywg cov khoom ntsuab.
3. Kev ua tau zoo tshaj plaws
Lub cev thiab cov khoom siv kho tshuab ntawm OSB yog qhov zoo tshaj plaws rau cov khoom siv hluav taws xob zoo tib yam, feem ntau muaj cov yam ntxwv hauv qab no:
(1) Los tiv thaiv deformation, tiv thaiv tev, tiv thaiv warping, nrog cov yam ntxwv xws li lub zog tsis sib xws thiab qhov loj me.
(2) Anticorrosive, mothproof, nplaim taws retardant, haum rau sab nraum zoov thiab kub-kub ib puag ncig;
(3) Kev ua haujlwm tsis zoo ntawm cov dej tsis zoo, tuaj yeem raug rau ib puag ncig ntuj thiab huab cua nyob rau lub sijhawm ntev;
(4) Muaj kev ua haujlwm zoo txhua yam, nws tuaj yeem txiav, drilled, thiab npaj rau txhua qhov kev taw qhia;
(5) Nws muaj cov rwb thaiv tsev zoo thiab lub suab rwb thaiv tsev, thiab cov xim zoo nkauj.
Daim ntawv thov ntawmOSB
1. Rooj tog
Cov khoom zoo ntawm lub cev thiab cov khoom siv hluav taws xob zoo ntawm lub rooj tsavxwm particle board txiav txim siab tias nws tuaj yeem siv los ua cov khoom thauj khoom rau cov rooj tog zaum xws li sofas, TV txee, txaj txaj, rooj thiab rooj zaum, thiab tuaj yeem siv rau hauv vaj huam sib luag rooj tog los ua cov khoom txee. , desktop panels, qhov rooj vaj huam sib luag, thiab lwm yam.
2. Kho kom zoo nkauj sab hauv
Oriented strand board yog qhov zoo nkauj heev, thiab cov ntoo sib txawv tuaj yeem nthuav tawm txawv textures thiab xim.Tsis zoo li cov khoom siv zoo nkauj thiab du, cov txheej txheem taw qhia strand particle board muaj qhov tshwj xeeb thiab ntxhib zoo nkauj ntawm nws qhov chaw vim yog txoj kab ntsug thiab kab rov tav ntawm cov flakes.Raws li cov khoom siv kho kom zoo nkauj, nws muaj cov nyhuv ntuj thiab vivid thaum siv rau hauv tsev kho kom zoo nkauj.
3. Cov ntaub ntawv ntim khoom
Oriented strand particle board yog ib qho kev lees paub thoob ntiaj teb kev tshuaj xyuas cov khoom ntim khoom dawb, uas muaj lub zog zoo dua thiab ua haujlwm tsis zoo dua li cov khoom siv ntoo.
