I-OSB yenziwe ngamapulangwe amakhulu okhuni anomumo ocacisiwe nobukhulu ngemuva kokunamathisela nokuwabeka ngendlela eqondisayo, bese icindezelwa ngokushisa ukuze kwakhiwe ibhodi lesakhiwo esinezingqimba eziningi, futhi ukushefa okungaphezulu kuqondiswe ngobude noma ububanzi bebhodi. .
Njengebhodi lesakhiwo, i-OSB iyamukelwa kancane kancane ngabathengi baseShayina ngenxa yamandla ayo aphezulu (eseduze ne-plywood), ukuzinza okuhle kwe-dimensional, ukuvikelwa kwemvelo, ububanzi bezinhlelo zokusebenza nokusebenza okuhle kokucubungula, okubuye kukhuthaze i-OSB e-China. ukuthuthukiswa kwe.
1. Ukulungiswa kwezinto zokusetshenziswa kwe-OSB
Ukulungiswa kwezinto ezingavuthiwe kungenye yezinqubo ezibalulekile ekukhiqizeni i-OSB. Ngemva kokucwecwa nokukhipha ukungcola entweni eluhlaza yokhuni, icutshungulwa ibe yi-shavings edingekayo ekukhiqizeni. Ngokuvamile, ubude be-shavings esetshenziselwa ukukhiqiza i-OSB buyi-100-120 mm, ububanzi buyi-20-50 mm, futhi ubukhulu buba ngu-0.6 mm. .
Ihlukile kumalogi anobubanzi obukhulu asetshenziswa ekukhiqizweni kwe-OSB yangaphandle, imithombo yezinto ezingavuthiwe ezisetshenziselwa ukukhiqiza i-OSB e-China ibanzi uma kuqhathaniswa futhi izinhlobo ziyinkimbinkimbi uma kuqhathaniswa. Ikakhulukazi izingodo ezikhula ngokushesha ezinobubanzi obuncane kanye nenani elikhulu lezinsalela ezicutshungulwayo, njenge-poplar, i-eucalyptus kanye nokhuni lwamagatsha. Ubone izinsalela zamapulangwe, njll.
1.1. I-OSB ye-flaker yomkhiqizo omude ikhiqiza ukushefa okukhulu
Ukukhiqizwa kokushefa okukhulu ngohlobo lwendandatho olude lokhuni ukumiswa kwendabuko kwenqubo yokulungiselela impahla yomugqa wokukhiqiza we-OSB. Okokuqala, izingodo zithunyelwa emshinini wokucwecwa ukuze zicwecwe. Izingodo ezihlutshiwe zidlula kumtshina wensimbi ukuze zikhiphe izingodo eziqukethe insimbi. Izingodo ezifanelekile zingena okhunini olude I-wood planer batch feeder ende, bese ithunyelwa ekamelweni lokusika lenqwaba yepulani yokhuni ende ngenqwaba ukuze isike ibe yizinsika.
Amapulani omkhiqizo omude asetshenziswa kakhulu ikakhulukazi ahlanganisa iplanethi yomkhiqizo omude wohlobo lwendandatho yommese, i-cutter head type planer yomkhiqizo omude kanye neplani yomkhiqizo wommese wohlobo olude, okuphakathi kwawo ukusetshenziswa kweplanethi yomkhiqizo omude wommese kubanzi kakhulu. Ipulani yomkhiqizo omude wohlobo lwendandatho yommese yakhiwe izingxenye ezimbalwa ezifana nesistimu yokuphakela inqwaba, indlela yokuqondanisa, into yokucindezela, igumbi lokusika elihambahambayo kanye nenjini yokushayela eyinhloko.
Umgomo wayo wokusebenza ufana nokulola ipensela ngommese wepensela. Ngemva kokuba ugodo lungene ekamelweni lokusika, igumbi lokusika leplanethi emide yokhuni liqhubekela phambili eduze nomzila wesitimela ngesivinini esingaguquki, futhi izingcezu zommese ozungezayo wangaphakathi usika indandatho eduze kwe-eksisi yelogi. Imimese eqondisayo kanye neyokushaya ukuze ilawule ubude, ububanzi nobukhulu bokushefa. Ubukhulu be-shavings obukhiqizwa uhlobo lwendandatho olude lwezinkuni lufana nomfaniswano, ukwakheka kwe-shavings kuhle, futhi okukhiphayo kuphezulu, okufanelekile emigqeni yokukhiqiza ye-OSB enkulu.

1.2. Ubuchwepheshe be-OSB obunezigaba ezimbili ukukhiqiza izingcezu ezinkulu zokushefa
Ukuvela kobuchwepheshe bokukhiqiza ukushefa kwezigaba ezimbili kwe-OSB kushintshe umlando wangaphambili wokusebenzisa izinkuni ezinobubanzi obukhulu kuphela ekukhiqizeni i-OSB. Izinto ezincane ezinjengokhuni lwegatsha, ukhuni olugobile, nezinsalela zokhuni ezisahliweyo zingasetshenziswa ukucubungula ukushefa kwezinkuni okuhlangabezana nokukhiqizwa kwe-OSB, ukwenza izinto zokusetshenziswa ze-OSB Ububanzi bunwetshiwe, okuye kwadambisa ukushoda kwezinto zokusetshenziswa kubakhiqizi be-OSB ngezinga elithile.
Ubuchwepheshe bokulungiselela ama-shavings ezingxenyeni ezimbili buhlukaniswe ngezinyathelo ezimbili: isinyathelo sokuqala ukudlulisa izinto zokusetshenziswa zokhuni ngokusebenzisa i-chipper eklanywe ngokukhethekile ukuze kukhiqizwe amapulangwe amakhulu okhuni anobude obungaba ngu-150 mm; Isinyathelo sesibili ukuhlunga izingodo ezinkulu ezisikiwe Susa ukungcola, bese ucubungula ama-flakes amakhulu anogqinsi luka-0.6 mm nobude obungaba ngu-150 mm ngokusebenzisa i-ring flaker eyenziwe kahle.
Uma kuqhathaniswa ne-flaker yokhuni olude lwendabuko, isilinganiso sobude bobukhulu be-shavings ecutshungulwa ubuchwepheshe bokulungiselela ukushefa kwezingxenye ezimbili kungcono. Ukwengeza, ngokungafani nama-shavings angama-rectangular alungiselelwe umshini omude we-flaking wokhuni, emaphethelweni e-shavings alungiswe yi-flaking enezigaba ezimbili ajwayelekile futhi awekho kuma-engeli alungile, futhi abe noshintsho olufana kakhulu lokucindezeleka okufanayo.

2. Ukomiswa kwe-OSB shavings
Izikomisi ze-OSB ngokuvamile zisebenzisa ezomisi ezinesiteshi esisodwa. Ubuchwepheshe bokomisa obujwayelekile obuphakathi nendawo abukwazi nje ukuhlangabezana nezidingo zokomisa ze-OSB shavings evamile, kodwa futhi kusetshenziselwe ukomisa okuxubile kwama-shavings amahle kanye nama-shavings amakhulu angenalutho ku-OSB izinto zokusetshenziswa ezingahlotshiswa.
Yonke inqubo yokomisa ihlukaniswe yaba izigaba ezintathu: ingxenye yokomisa, ingxenye yokomisa, kanye nesigaba sokulinganisa ukuze kuqinisekiswe ukuthi umswakama wokushefa kokugcina ulawulwa cishe ku-2%. Ukusebenzisa ukugeleza komoya kwe-outlet fan ye-dryer, ama-shavings amahle adlula esomisi ngokushesha ngenxa yobukhulu bawo obuncane nesisindo esincane;
Ngaphansi kwesenzo esiphindwe kabili sefosholo ngaphakathi kwesomisi kanye nokugeleza komoya, ama-shavings aphakathi nendawo asesimweni sokumiswa mahhala ukuze aqedele ukomisa; kuyilapho ama-shavings amakhulu ejikeleziswa eduze kodonga lwangaphakathi lwe-dryer ukuqedela ukomisa. Isikhathi kanye nomzila odluliswayo zinde, ukuze umswakama we-shavings ophuma ekugcineni ufana.

3. Ukuhlungwa kwe-OSB shavings
Kunezinhlobo ezimbili zokuhlelwa kwe-shavings, enye iwukusebenzisa izindlela zemishini ukuhlunga ukushefa ngokosayizi wejometri ngokusebenzisa amagridi ezikhala ezihlukene noma izikhala ezibekiwe, kanti enye iwukuhlukanisa ukushefa ngokuqina okuhlukene kanye nezilinganiso zokumiswa ngokulungisa ukugeleza komoya. isivinini. ukuhlunga.
Ama-shaving aphuma ekomeni ngokuvamile ahlukaniswa ngezindlela ezimbili, enye iwukushefa okukhulu okwehla ngokuqondile ebhokisini lokukhipha okokomisa, kanti enye i-shavings emihle exutshwa igesi yomsila wokoma futhi ikhishwe futhi iqoqwe. ngesishingishane sokugaywa kabusha. Ukuze kuthuthukiswe ukusebenza kahle kokuhlunga, kuvame ukunconywa ukuhlukanisa imifudlana emibili yokushefa ukuze kuhlolwe.
Imishini esetshenziswa kakhulu yokuhlola ukushefa ihlanganisa izikrini zezigubhu, izisefo zamadiski, nezisefo zokushwiba. Ukukhethwa kwemishini yokuhlola ukushefa yemigqa yokukhiqiza ye-OSB kuncike kumthamo wokukhiqiza kanye nokuma kokushefa.

4. Usayizi we-OSB shavings
Ama-shaving ahlungiwe angena kusisele sokushefa esomile sengqimba ewumgogodla ongaphezulu ngokulandelanayo. Ukuze kuqinisekiswe ukuthi ama-shavings awabhubhisi ku-silo, impahla ikhishwa ngokushelelayo futhi ukuma kwe-shavings akukonakali, i-silo yokugcina ama-shavings iyimpahla evundlile eyenziwe ngokukhethekile. inqolobane.
Kukhona induku yokusekela phakathi nendawo yomshini wokuxuba i-roller glue, lapho inani elithile lamakhanda e-atomizing aklanyelwe futhi afakwe), iglue, i-emulsion kapharafini, i-ejenti yokwelapha nezinye izithasiselo zixutshwe nama-shavings emshinini wokuxuba iglue ngokusebenzisa. ikhanda le-atomizing.
Ibha yomhlahlandlela efakwe odongeni lwangaphakathi lwe-glue mixer iletha amandla amaphakathi we-shavings azungezisa isilinda ukuya ohlangothini lwewashi ngo-11:00. Ama-shavings aqeda ukulinganisa ngesikhathi senqubo yokuwa yamahhala, futhi ama-shavings kumxube weglue azolandela isiqondiso se-glue mixer. Ukuzungezisa kwesilinda kulethwa phezulu naphansi izikhathi eziningi ukuze kukangwe ngokuphindaphindiwe.
5. I-Pavement ye-OSB shavings
I-surface core shavings emva kokuxutshwa kweglue ithunyelwa ku-surface core layer metering silo yesiteshi sokugandaya, bese igandaywa ngekhanda ngalinye eligandayiwe. Indawo egandaywe yi-OSB yendabuko iyi-3-layer structure, okungukuthi, izingqimba eziphezulu nezingaphansi kanye ne-core layer. Phakathi kwazo, indlela yokugandaya yezingqimba ezingaphezulu nezingaphansi iwukuvula isiqondiso ekuqondeni kobude, kanti ama-shavings amakhulu abanzi futhi amade avulwa ngokuqondile phezu kongqimba olungaphezulu; indlela yokugandaya ye-core layer iwukugandaywa okuqondile okuqondile, futhi ama-shavings amancane ahlukaniswe kahle agandaywe ongqimbeni oluyisisekelo.
Iyunithi yokukala ingahlanganiswa ngaphansi kwesisele semitha yokushefa, futhi isikali sebhande lemitha elifakwe ngaphansi kwesisele semitha esigandayiwe singalungisa inani lokuphakela ngesikhathi ngokuya ngokuphambuka koshintsho lwenqwaba ye-shavings, ukuze finyelela ukulawula okunembile, okugcwaliswa ngokuqondile ngekhanda lokugandaya I-chipboard pavement yakha isakhiwo se-slab.
