OSB yog ua los ntawm cov ntoo loj loj ntawm cov duab thiab tuab tom qab gluing thiab nteg lawv nyob rau hauv ib qho kev taw qhia, thiab tom qab ntawd kub-nias los tsim ib tug ntau txheej txheej pawg thawj coj saib, thiab cov nto shavings yog oriented raws qhov ntev los yog dav ntawm lub rooj tsavxwm. .
Raws li lub rooj tsav xwm txheej txheem, OSB tau maj mam lees txais los ntawm Suav cov neeg siv khoom vim nws lub zog siab (ze rau plywood), zoo qhov ruaj khov, kev tiv thaiv ib puag ncig, ntau yam kev siv thiab kev ua haujlwm zoo, uas kuj txhawb OSB hauv Suav teb. kev loj hlob ntawm.
1. Kev npaj ntawm OSB raw khoom
Kev npaj cov khoom raw yog ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim OSB. Tom qab tev thiab tshem tawm impurities los ntawm cov khoom siv ntoo, nws tau ua tiav rau hauv cov shavings xav tau rau kev tsim khoom. Feem ntau, qhov ntev ntawm cov shavings siv los tsim OSB yog 100-120 hli, qhov dav yog 20-50 hli, thiab thickness yog li 0.6 hli. .
Qhov sib txawv ntawm qhov loj-ntev cav siv nyob rau hauv txawv teb chaws OSB ntau lawm, qhov chaw ntawm raw cov ntaub ntawv siv los tsim OSB nyob rau hauv Tuam Tshoj yog kuj dav thiab cov hom kuj nyuaj. Lawv feem ntau yog me me-ntev ceev-loj cav thiab ib tug loj tus naj npawb ntawm cov residues, xws li poplar, eucalyptus thiab ceg ntoo. Pom cov ntoo seem, thiab lwm yam.
1.1. OSB ntev cov khoom flaker tsim cov shavings loj
Kev tsim cov shavings loj los ntawm lub nplhaib-hom ntev ntoo flaker yog cov txheej txheem ib txwm ua ntawm cov txheej txheem npaj cov khoom ntawm OSB cov kab ntau lawm. Ua ntej, cov cav raug xa mus rau lub tshuab tev tawm rau tev. Cov cav tev tawm dhau los ntawm cov hlau ntes kom tshem tawm cov cav uas muaj hlau. Cov cav tsim nyog nkag mus rau hauv cov ntoo ntev Lub dav ntoo planer batch feeder, thiab tom qab ntawd xa mus rau chav txiav ntawm qhov ntev ntoo planer batch los ntawm batch txiav rau hauv shavings.
Feem ntau siv cov khoom siv ntev ntev feem ntau suav nrog riam nplhaib hom khoom siv ntev, txiav lub taub hau hom khoom siv ntev thiab riam ncej hom khoom ntev planer, ntawm cov ntawv thov riam nplhaib ntev khoom planer yog dav tshaj. Riam nplhaib hom ntev khoom planer yog tsim los ntawm ntau qhov chaw xws li batch feeding system, alignment mechanism, nias fixture, mobile txiav chamber thiab lub ntsiab tsav lub cev muaj zog.
Nws txoj hauv kev ua haujlwm zoo ib yam li kev ua kom cov cwj mem nrog rab riam. Tom qab lub cav nkag mus rau hauv lub txiav chamber, lub txiav chamber ntawm cov ntoo ntev planer nce mus raws cov kev taw qhia rail ntawm ib tug tas mus li ceev, thiab sab hauv rotating riam nplhaib hlais raws lub axis ntawm lub cav. Kev taw qhia thiab qhab nia riam los tswj qhov ntev, dav thiab tuab ntawm cov shavings. Lub thickness ntawm cov shavings tsim los ntawm lub nplhaib-hom ntev ntoo flaker yog ib yam nkaus, cov duab ntawm cov shavings yog zoo, thiab cov zis yog siab, uas yog haum rau loj-muaj peev xwm OSB ntau lawm kab.

1.2. OSB ob-section thev naus laus zis los tsim cov khoom loj ntawm shavings
Kev tshwm sim ntawm ob-theem OSB loj-scale shaving tshuab tau hloov cov keeb kwm yav dhau los ntawm tsuas yog siv cov ntoo loj hauv kev tsim OSB. Cov ntaub ntawv me me xws li cov ceg ntoo, khoov ntoo, thiab cov ntoo saws tuaj yeem siv los ua cov ntoo shavings uas ua tau raws li OSB ntau lawm, ua OSB raw cov ntaub ntawv tau nthuav dav, uas tau txo qis cov khoom siv raw rau OSB cov tuam txhab. ib qho twg.
Ob ntu shavings npaj tshuab tau muab faib ua ob kauj ruam: thawj kauj ruam yog kom dhau cov khoom siv ntoo los ntawm cov khoom siv tshwj xeeb tsim los tsim cov ntoo loj nrog qhov ntev txog 150 hli; Cov kauj ruam thib ob yog txhawm rau tshuaj xyuas cov txiav ntoo loj tshem tawm cov impurities, thiab tom qab ntawd ua cov flakes loj nrog lub thickness ntawm 0.6 hli thiab ntev li ntawm 150 hli los ntawm lub nplhaib zoo nkauj flaker.
Piv nrog rau cov tsoos ntev ntoo flaker, qhov ntev-thickness piv ntawm cov shavings ua tiav los ntawm ob ntu shaving npaj tshuab yog zoo dua. Tsis tas li ntawd, tsis zoo li cov duab plaub shavings npaj los ntawm lub cav ntoo ntev ntev, cov npoo ntawm cov shavings npaj los ntawm ob-theem flaking yog qhov tsis sib xws thiab tsis nyob ntawm cov ces kaum, thiab muaj qhov sib txawv ntawm qhov sib txawv.

2. Kev ziab ntawm OSB shavings
OSB tshuab ziab khaub ncaws feem ntau siv ib lub tshuab ziab khaub ncaws. Lub tshuab ziab khaub ncaws nruab nrab kub tsis tuaj yeem tsuas yog ua tau raws li qhov xav tau kom qhuav ntawm cov pa OSB shavings, tab sis kuj tseem siv rau kev sib xyaw kom qhuav ntawm cov shavings zoo thiab flaky loj shavings hauv OSB raw cov ntaub ntawv uas tuaj yeem dai kom zoo nkauj.
Tag nrho cov txheej txheem ziab yog muab faib ua peb theem: ntu ua ntej ziab, ntu kom qhuav, thiab ntu sib npaug kom ntseeg tau tias cov ntsiab lus noo noo ntawm qhov kawg shavings yog tswj ntawm li 2%. Siv cov cua ntws ntawm lub qhov hluav taws xob kiv cua ntawm lub tshuab ziab khaub ncaws, cov shavings zoo dhau los ntawm lub tshuab ziab khaub ncaws sai vim lawv qhov me me thiab lub teeb yuag;
Nyob rau hauv ob qhov kev txiav txim ntawm lub duav hauv lub tshuab ziab khaub ncaws thiab cov cua ntws, cov shavings nruab nrab yog nyob rau hauv lub xeev pub dawb kom ua tiav qhov ziab; thaum cov shavings loj yog tig raws phab ntsa sab hauv ntawm lub tshuab ziab khaub ncaws kom tiav cov ziab. Lub sij hawm thiab txoj kev dhau los kuj ntev, yog li ntawd cov dej noo ntawm cov shavings uas thaum kawg tuaj tawm ntawm lub tshuab ziab khaub ncaws yog uniform.

3. Kev txheeb xyuas ntawm OSB shavings
Muaj ob hom shavings sorting, ib qho yog siv cov cuab yeej siv los txheeb cov shavings raws li qhov loj me los ntawm cov kab sib txawv ntawm cov apertures los yog teeb qhov sib txawv, thiab lwm qhov yog cais cov shavings nrog qhov sib txawv ntawm qhov sib txawv thiab kev ncua kev sib piv los ntawm kev kho cov cua ntws. ceev. kev xaiv.
Cov shavings tawm ntawm lub tshuab ziab khaub ncaws feem ntau muab faib ua ob txoj hauv kev, ib qho yog cov shavings loj uas tuaj ncaj qha los ntawm lub thawv tso tawm ntawm lub tshuab ziab khaub ncaws, thiab lwm yam yog cov shavings zoo uas sib xyaw rau hauv cov roj cua kom qhuav thiab tawm thiab sau. los ntawm kev siv cyclone. Txhawm rau txhawm rau txhim kho kev ua haujlwm zoo, nws feem ntau pom zoo kom cais cov kwj ntawm ob lub shavings rau kev tshuaj ntsuam.
Feem ntau siv cov khoom siv tshuaj ntsuam xyuas rau kev tshuaj ntsuam shavings suav nrog cov ntxaij vab tshaus, disc sieves, thiab viav vias sieves. Kev xaiv cov khoom siv tshuaj ntsuam xyuas shavings rau OSB cov kab ntau lawm nyob ntawm qhov muaj peev xwm thiab cov duab ntawm cov shavings.

4. Sizing ntawm OSB shavings
Cov sorted shavings nkag mus rau qhuav shaving silo ntawm lub nto core txheej feem. Txhawm rau kom ntseeg tau tias cov shavings tsis txuas rau hauv lub silo, cov khoom siv tau tawm kom zoo thiab cov duab ntawm cov shavings tsis puas, lub silo rau khaws cov shavings yog cov khoom siv tshwj xeeb tsim kab rov tav. lub tsev khaws khoom.
Muaj cov pas nrig txhawb nqa hauv nruab nrab ntawm cov menyuam cov kua nplaum sib xyaw tshuab, uas muaj qee tus naj npawb ntawm atomizing lub taub hau tsim thiab ntsia), kua nplaum, paraffin emulsion, curing agent thiab lwm yam khoom siv ntxiv nrog cov shavings hauv cov kua nplaum sib tov los ntawm lub taub hau atomizing.
Daim ntawv qhia bar inlaid rau sab hauv phab ntsa ntawm cov kua nplaum sib tov coj cov centrifugal quab yuam ntawm cov shavings tig nrog lub tog raj kheej mus rau clockwise kev taw qhia ntawm 11:00. Cov shavings tiav sizing thaum lub caij nplooj zeeg dawb, thiab cov shavings hauv cov kua nplaum tov yuav ua raws li cov kev taw qhia ntawm cov kua nplaum tov. Kev sib hloov ntawm lub tog raj kheej yog nqa tuaj thiab nqis ntau zaus rau kev rov ua dua.
5. Pavement ntawm OSB shavings
Cov core nto shavings tom qab cov kua nplaum sib tov yog xa mus rau cov tub ntxhais txheej txheej metering silo ntawm qhov chaw nres tsheb paving, thiab tom qab ntawd paved los ntawm txhua lub taub hau paving. Cov tsoos OSB pavement yog 3-txheej qauv pavement, uas yog, sab sauv thiab sab saum toj txheej thiab cov tub ntxhais txheej. Ntawm lawv, txoj kev paving ntawm cov khaubncaws sab nraud povtseg ntawm sab sauv thiab sab hauv qab yog kev taw qhia paving nyob rau hauv qhov ntev kev taw qhia, thiab qhov dav thiab ntev loj shavings yog ncaj qha paved ntawm txheej txheej; txoj kev paving ntawm cov tub ntxhais txheej yog kab rov tav directional paving, thiab cov finely faib sub-me shavings yog paved ntawm cov tub ntxhais txheej.
Lub ntsuas qhov hnyav tuaj yeem ua ke rau hauv qab ntawm shavings metering silo, thiab metering siv nplai ntsia rau hauv qab ntawm pavement metering silo tuaj yeem kho tus nqi noj nyob rau lub sijhawm raws li qhov sib txawv ntawm qhov sib txawv ntawm cov shavings bulk ntom, thiaj li. ua tiav kev tswj hwm, uas ncaj qha ua tiav los ntawm lub taub hau paving Lub chipboard pavement tsim cov qauv slab.
